Heat exchangers are well known in the art. Heat exchangers are generally used when it is desired to transfer heat from a first heat exchange medium to a second heat exchange medium. The first heat exchange medium generally flows within the heat exchanger, while the second heat exchange medium flows outside of the heat exchanger. A tube and chamber type heat exchanger is a variant of a heat exchanger, typically characterized by having a medium directing insert disposed within a chamber of the heat exchanger, wherein the medium directing insert extracts as much performance out of any given heat transfer surface area by inducing mixing and agitating effect to the heat exchange medium flowing inside the heat exchanger, a mechanism known in the art to enhance heat transfer performance of the heat exchange medium by minimizing formation of boundary layers detrimental to effective heat transfer. The tube and chamber type heat exchangers are further characterized by enhancing the heat transfer performance without reverting to using surface enhancements, generally eliminating the need of having secondary surface extensions, such as fins, to realize enhanced heat transfer performance. Generally, a heat exchanger of this kind performs at a very high efficiency level, indicated by a higher overall heat transfer coefficient throughout its available surface area, lending to a smaller heat exchanger package compared to a conventional heat exchanger design known in the art. A smaller heat exchanger package lends itself to further benefits, such as lighter weight, less material usage, and lower overall assembly cost. Reduced parts count as a result further lends itself to an easier manufacturing process. A typical tube and chamber heat exchanger is characterized by having a distinct inlet and outlet sections, a chamber section, and a medium directing insert disposed within the chamber section.
The present invention is an improved tube and chamber heat exchanger utilizing an enhanced modular medium directing insert design, providing means to obtain desired performance characteristics while having a flexible modular medium directing assembly design allowing for means to minimize tooling costs. The enhanced modular medium directing assembly features a parallelepiped body, longitudinally disposed within a chamber section of the heat exchanger, extending longitudinally outwardly out of an inlet side frontal plane established by the chamber section, as well as extending longitudinally outwardly out of an outlet side backward plane established by the chamber section, whereby the longitudinal length of the medium directing insert assembly is distinctly longer than the longitudinal boundary established by the chamber section. A first end of the longitudinally extended medium directing assembly is coupled to a first sub-chamber section provided on the inlet side chamber section extending outwardly from the frontal plane established by the chamber section, while a second end of the longitudinally extended medium directing assembly is coupled to a second sub-chamber section provided on an outlet side of the chamber section, extending outwardly from the backward plane established by the chamber section.
In a tube and chamber heat exchanger design, the narrowest pathway typically found within the heat exchanger for the first heat exchange medium, and therefore the main cause for heat exchange medium flow pressure drop, may be generally found within the flow path provided within the medium directing insert. It may be desirable to minimize pressure drop effect to the heat exchange medium flow, as such effect may have detrimental effect to the heat exchanger performance. In order to minimize pressure drop effect to the heat exchange medium, the entire chamber section may be expanded volumetrically to expand the flow path available within the medium directing insert. However, doing so may detrimentally affect the performance of the heat exchanger. As the overall flow path within the chamber section is expanded, it may have an adverse effect of slowing the velocity of the heat exchange medium, which may negatively affect the performance of the heat exchanger.
The present invention provides for means to enlarging the narrowest pathway generally found within a tube and chamber heat exchanger, without expanding the entire flow space provided within the chamber section, therefore providing means to significantly reduce the pressure drop effect to the heat exchange medium while maintaining the highest performance yield available out of a tube and chamber type heat exchanger, by maintaining high heat exchange medium velocity within the chamber section of the heat exchanger. The desirable effect is achieved by extending the longitudinal axial length of the medium directing assembly over the longitudinal axial length of the chamber section, thereby expanding the flow path available within the medium directing assembly longitudinally, coupling a first end of the medium directing assembly within the first sub-chamber provided externally of the chamber section while coupling a second end of the medium directing assembly within the second sub-chamber, which is also provided externally of the chamber section. Furthermore, with the present invention, means to finely tune the velocity of the heat exchange medium flowing within the heat exchanger chamber section is provided, wherein desired velocity of the heat exchange medium may be achieved by varying the spatial separation between the two lateral sides of the medium directing assembly and the lateral wall of the chamber section. To further reduce the effect of the pressure drop to the heat exchange medium flowing within the heat exchanger, a sub-chamber anterior wall of the first sub-chamber and a sub-chamber posterior wall of the second sub-chamber may be omitted of planar material, providing for means to expand and maximize an inlet flow path for the heat exchange medium as well as expand and maximize the outlet flow path for the first heat exchange medium, greatly reducing the pressure drop effect to the heat exchange medium flowing within the heat exchanger.
In the present invention, the first sub-chamber may feature at least one planar panel member engagingly coupled to at least one exterior plane of the generally rectangular parallelepiped medium directing assembly. In a similar fashion, the second sub-chamber may feature at least one planar panel member engagingly coupled to at least one exterior plane of the generally rectangular parallelepiped medium directing assembly. It may be a desirable feature to have at least one planar panel member either on the first sub-chamber, the second sub-chamber, or on both the first sub-chamber and the second sub-chamber engagingly couple at least one exterior plane of the parallelepiped medium directing assembly, as such feature may prevent any rotational movement from taking place, wherein the medium directing assembly unintentionally rotates within the chamber section of the heat exchanger during assembly or during use. It is not desirable to have any rotational movement from taking place, as such movement may have detrimental effect to the heat exchanger performance, by diverting away from function as was designed and intended. Furthermore, movement of the medium directing assembly within the chamber assembly may lead to a premature failure of the heat exchanger, as friction between the respective components may lead to excessive wear of the components, potentially leading to a formation of a hole on the heat exchanger assembly body, leading to a catastrophic failure rendering the heat exchanger useless. Mechanical means to position and couple the medium directing assembly within the chamber allows for cost savings as bonding the components by separate means may be omitted, if desired. In the event some adhesive or bonding means are utilized to couple the two parts together, having the mechanical coupling means in addition to bonding or adhesive means provides added structural rigidity, especially desirable in high pressure heat exchanger applications, such as in applications requiring heat exchange medium with high operational pressure, such as with refrigerant gas or steam, for example.
The first sub-chamber section and the second sub-chamber section having a generally parallelepiped body with at least one generally planar panel, allows for means to positively engage the similarly shaped generally rectangular parallelepiped medium directing assembly in a specific manner. It may be desirable to have means to engage the medium directing assembly in a specific orientation, as it may allow easier means to orient the medium directing assembly as intended, assuring desired design to be obtained, and by extension, obtain desired performance characteristics.
The first sub-chamber section, the second sub-chamber section, combined with longitudinally extended medium directing insert assembly further provides for means to maximize the inlet flow path and the outlet flow path of the heat exchange medium, by longitudinally extending the medium directing assembly out from the longitudinal boundary established by the chamber section, thereby by extension, expanding the narrowest flow path for the first heat exchange medium within the heat exchanger. The expanded flow path contributes to less restrictive flow of the first heat exchange medium within the heat exchanger, minimizing pressure drop effect to the heat exchange medium, which is generally a desirable feature in a heat exchanger, by reducing the energy needed to pump the heat exchange medium within the heat exchanger. As the flow path permitted within the medium directing assembly is generally the most restrictive aspect to the flow of the heat exchange medium within the tube and chamber type heat exchanger, it is a desirable feature to expand the flow path of the heat exchange medium available within the medium directing assembly, minimizing pressure drop effect to the heat exchange medium flow. Similarly, having means to enlarge the heat exchange medium flow path within the medium directing assembly without enlarging the overall chamber section flow path may be desirable, as enlarging the overall chamber section to provide added flow area for the heat exchange medium may reduce the heat exchange medium velocity, which may be undesirable as reduced velocity generally reduces the heat transfer performance. The present invention provides means to enlarging the narrowest flow path of the heat exchange medium within the heat exchanger, generally found within the medium directing assembly, without enlarging the overall flow path found within the chamber section of the heat exchanger, assuring desired high heat transfer performance to be achieved.
The present invention features a modular medium directing assembly design wherein the medium directing assembly is generally divided into at least two components comprising of a first top half body and a second bottom half body, providing for means to minimize tooling costs. For cost effective manufacturing of a components generally comprising of planar materials, stamping process is generally utilized to maximize production efficiency and to lower component costs. As tooling costs generally increase incrementally as stamping stations are increased, tooling that can produce the medium directing insert in a single tooling may lead to a prohibitively expensive tooling, also resulting in manufacturing complications. Furthermore, a single tooling with high number of stamping stations generally require production machines to run at a lower production speed, generally increasing the production cost of a heat exchanger. Single tooling design further leads to less flexibility to accommodate more than one medium directing insert design. By dividing the medium directing insert into at least two halves, tooling complexity may be minimized by requiring reduced stamping stages, thereby drastically reducing the tooling costs. Reduced stamping stages permit higher production speed to be utilized, lending itself to cost efficiency and lower production costs. Tooling with less stages and complexity are generally very economical to procure, requiring less technical complexity or tooling specialization know-how, lending to an expanded pool of potential tooling suppliers, whereby with more competition lends to lower tooling costs. Having lower initial capital investment in tooling may allow for means to cater to a plurality of specific heat exchanger application use without incurring significant tooling investment expenditure, which may be a desirable feature to maximize profit margin or have means to cost effectively cater to a plurality of customer needs with a variety of product design catered to specific application use. By reducing the medium directing insert into two components, just one half of the medium directing insert may be changed over for another design, while leaving the second half as same, permitting means to cater to a variety of customer needs while reducing the investment required in tooling effectively in half Minimizing tooling costs further results in lower components cost, thereby resulting in cost competitive heat exchanger assembly by extension.
Improvements made to the medium directing insert design lends itself to improved heat transfer characteristics, which in turn offers opportunity to develop smaller heat exchanger assemblies while maintaining the same performance specifications. Smaller assemblies offer opportunities to save costs on raw materials, which directly translates to lower assembly costs and other cost savings.
The invention is directed to an improved tube and chamber type heat exchanger, which improves the heat transfer performance by minimizing pressure drop effect to a first heat exchange medium directed into the internal flow path of the heat exchanger. The pressure drop effect to the first heat exchange medium may be minimized by providing means to enlarging the pathway that is typically the narrowest flow path found within a typical tube and chamber type heat exchanger, generally found within the medium directing insert. The invention also provides means to reduce tooling cost as well as improve manufacturability of the heat exchanger, thereby by extension, reducing the overall cost of the heat exchanger.
The heat exchanger generally utilizes two heat exchange mediums with the first heat exchange medium flowing inside the heat exchanger, while a second heat exchange medium generally flowing outside of the heat exchanger.

Instead, one or more of the lateral or vertical sides of the second longitudinal end of the medium directing assembly may be positionally located and engage one or more of the lateral or vertical panels comprising the cavity within the second sub-chamber.
Disposed within the medium directing assembly is a medium directing panel. The medium directing panel is generally a planar body, having a first planar surface facing at an angle towards the medium directing inlet and the medium directing distribution outlet, while having a second planar surface facing at an angle towards the medium directing outlet and the medium collecting inlet. In an embodiment of the present invention, the medium directing panel has a first longitudinal end and a second longitudinal end, comprising a medium directing panel anterior termination edge and a medium directing panel posterior termination edge, respectively. The medium directing panel anterior termination edge generally engages the medium directing lower first lateral support while the medium directing panel posterior termination edge generally engages the medium directing upper second lateral support. A first lateral edge of the medium directing panel generally engages the medium directing first side wall, while a second lateral edge of the medium directing panel generally engages the medium directing second side wall. The medium directing panel is generally disposed at an angle in relationship to the longitudinal axial characteristics established by the generally rectangular parallelepiped body of the medium directing assembly, generally facing at an angle the medium directing inlet and the medium directing distribution outlet.
In an embodiment of the present invention, as the first heat exchange medium is introduced in to the medium directing assembly through the medium directing inlet, the first heat exchange medium generally initially flows in a first line of flow within the medium directing assembly following the longitudinal axial characteristic of the rectangular parallelepiped body of the medium directing assembly in a pathway comprising vertically of the medium directing upper first lateral support and the medium directing lower first lateral support, and laterally of the medium directing first side wall and the medium directing second side wall. As the first heat exchange medium flow travels through the medium directing assembly, the first heat exchange medium flow characteristics may be regulated to maximize the heat transfer efficiency as the first heat exchange medium is prepared for successive flow pattern prepared within the medium directing assembly. As the first heat exchange medium travels further inward within the medium directing assembly from the medium directing inlet, the first heat exchange medium flowing initially in the first line of flow is directed to collide into the first planar surface of the medium directing panel with maximal impact, improving heat transfer efficiency by minimizing formation of boundary layer to the first heat exchange medium. The action of disrupting formation of boundary layer to the heat exchange medium is known in the art to improve heat transfer efficiency.
As the first heat exchange medium is directed to flow into the first planar surface of the medium directing panel, the first heat exchange medium is disbursed on the first planar surface of the medium directing panel, resulting in a second flow pattern that is divergent from the first line of flow. Furthermore, as the first planar surface of the medium directing panel is coupled within the medium directing assembly at an angle in relation to the longitudinal axial characteristics of the medium directing assembly facing both the medium directing inlet and the medium directing distribution outlet, while laterally bound by the medium directing first side wall and the medium directing second side wall, the first heat exchange medium that was disbursed on the surface of the first planar surface of the medium directing panel in the second flow pattern is further directed to flow out of the medium directing assembly and into the main chamber through the medium directing distribution outlet, in a third line of flow. In the third line of flow, the first heat exchange medium is projected out of the medium directing distribution outlet in a focused stream into the main chamber.
In the third line of flow, the first heat exchange medium generally travels vertically upwardly from the medium directing assembly as the first heat exchange medium exits through the medium directing distribution outlet. As the third line of flow travels through the main chamber, the third line of flow terminates as the first heat exchange medium impacts the lateral wall of the main chamber comprising the first chamber wall and the second chamber wall, within a perimeter of the lateral wall of the main chamber vertically in line with the medium distribution outlet. As the third line of flow impacts the lateral wall of the main chamber, the disruption to the flow of the heat exchange medium further reduces the formation of boundary layer to the heat exchange medium, known in the art to improve heat transfer efficiency.
As the third line of flow contacts the lateral wall of the main chamber, the third line of flow terminates and a pair of fourth line of flow begins within the main chamber. The pair of fourth line of flow within the main chamber for the first heat exchange medium are divergent lateral flows within the main chamber. The first fourth line of flow travels from generally the top vertical area of the main chamber where the third line of flow terminates, traveling in the flow space provided between the lateral wall of the main chamber, comprising the first chamber wall and the second chamber wall, and the medium directing first side wall. The second fourth line of flow travels from the top vertical area of the main chamber where the third line of flow terminates, traveling in the flow space provided between the lateral wall of the main chamber, comprising the first chamber wall and the second chamber wall, and the medium directing second side wall. The pair of fourth line of flow are generally directed to travel to an area vertically generally directly below the medium directing collecting inlet, at which point the pair of fourth line of flow collide in to each other and merge into a singular flow, further causing disruption to the first heat exchange medium flow, minimizing formation of boundary layer to the first heat exchange medium that may negatively impact the heat transfer efficiency.
The merging of the pair of the fourth line of flow terminates the fourth line of flow and initiates a fifth line of flow, wherein the fifth line of flow is generally perpendicular to the plane established by the opening of the medium directing collecting inlet. In the fifth line of flow, the first heat exchange medium is discharged out of the main chamber and introduced back into the medium directing assembly through the medium directing collecting inlet, in a focused stream. As the fifth line of flow travels further into the medium directing assembly, the first heat exchange medium is directed to collide with the second planar surface of the medium directing panel, wherein the first heat exchange medium disburses on the surface of the second planar surface of the medium directing panel, initiating a sixth flow pattern. The action of disbursing the heat exchange medium on a planar surface is known in the art to minimize formation of boundary layer, greatly enhancing the heat transfer efficiency of the heat exchanger.

In an embodiment of the present invention, as the first heat exchange medium is introduced in to the medium directing assembly 220 through the medium directing inlet 410, the first heat exchange medium generally initially flows within the medium directing assembly 220 in a first line of flow following the longitudinal axial characteristic of the rectangular parallelepiped body of the medium directing assembly 220 in a pathway comprising vertically of the medium directing upper first lateral support 245 and the medium directing lower first lateral support 250, and laterally of the medium directing first side wall 240 and the medium directing second side wall 235. As the first heat exchange medium travels further inward within the medium directing assembly 220 from the medium directing inlet 410, the first heat exchange medium flowing initially in the first line of flow is directed to collide into the first planar surface of the medium directing panel 255.
As the first heat exchange medium is directed to flow into the first planar surface of the medium directing panel 255, the first heat exchange medium is disbursed on the first planar surface of the medium directing panel 255, resulting in a second flow pattern that is divergent from the first line of flow. Furthermore, as the first planar surface of the medium directing panel 255 is coupled within the medium directing assembly 220 at an angle in relation to the longitudinal axial characteristics of the medium directing assembly 220 facing both the medium directing inlet 410 and the medium directing distribution outlet 420, while laterally bound by the medium directing first side wall 240 and the medium directing second side wall 235, the first heat exchange medium that was disbursed on the surface of the first planar surface of the medium directing panel 255 in the second flow pattern is further directed to flow out of the medium directing assembly 220 and into the main chamber 215 through the medium directing distribution outlet 420, in a third line of flow. The third line of flow is generally perpendicular in relation to the plane established by the opening of the medium distribution outlet 420, as well as generally perpendicular in relation to the longitudinal axial flow characteristics established by the first line of flow.
As the third line of flow is generally perpendicular in relation to the initial line of flow established in the first line of flow, the first heat exchange medium generally travels vertically upwardly from the medium directing assembly 220 as the first heat exchange medium exits the medium directing assembly 220 through the medium distribution outlet 420. The first heat exchange medium is generally projected out of the medium directing assembly 220 in a focused stream through the medium directing distribution outlet 420 in to the main chamber 215. As the third line of flow travels through the main chamber 215, the third line of flow terminates as the third line of flow reaches the lateral wall of the main chamber 215 comprising the first chamber wall 115 and the second chamber wall 120, within a perimeter of the lateral wall of the main chamber 215 vertically in line with the medium distribution outlet 420. As the third line of flow contacts the lateral wall of the main chamber 215, the third line of flow terminates and a pair of fourth line of flow begins within the main chamber 215.
The pair of fourth line of flow within the main chamber 215 for the first heat exchange medium are divergent lateral flows within the main chamber 215. The first fourth line of flow travels from generally the top vertical area of the main chamber 215 where the third line of flow terminates, traveling in the flow space provided between the lateral wall of the main chamber 215, comprising the first chamber wall 115 and the second chamber wall 120, and the medium directing first side wall 240. The second fourth line of flow travels from the top vertical area of the main chamber 215 where the third line of flow terminates, traveling in the flow space provided between the lateral wall of the main chamber 215, comprising the first chamber wall 115 and the second chamber wall 120, and the medium directing second side wall 235. The pair of fourth line of flow are generally directed to travel to an area vertically generally directly below the medium directing collecting inlet 425, following the lateral wall contour of the main chamber 215. Once the pair of fourth line of flow travel to the area vertically generally directly below the medium collecting inlet 425 within the main chamber 215, the pair of fourth line of flow collide in to each other and merge into a singular flow.
The merging of the pair of fourth line of flow terminates the pair of fourth line of flow and initiates a fifth line of flow within the main chamber 215, wherein the fifth line of flow is generally vertically perpendicular to the plane established by the opening of the medium directing collecting inlet 425. In the fifth line of flow, the first heat exchange medium is discharged out of the main chamber 215 and introduced back into the medium directing assembly 220 through the medium directing collecting inlet 425, in a focused stream. As the fifth line of flow travels further into the medium directing assembly 220, the first heat exchange medium is directed to collide with the second planar surface of the medium directing panel 255, wherein the first heat exchange medium disburses on the surface of the second planar surface of the medium directing panel, initiating a sixth flow pattern.
As the second planar side of the medium directing panel 255 faces at an angle the medium directing collecting inlet 425 and the medium directing outlet 415, the first heat exchange medium that was disbursed on the surface of the second planar side of the medium directing panel 255 in a sixth flow pattern is further directed to flow in a seventh line of flow following the longitudinal axial characteristics of the medium directing assembly 220 in a pathway provided within the medium directing assembly 220 comprising vertically of the medium directing upper second lateral support 265 and the medium directing lower second lateral support 295, and laterally of the medium directing first side wall 240 and the medium directing second side wall 235. As the first heat exchange medium flows within the medium directing assembly 220 in a seventh line of flow, the first heat exchange medium is directed to flow towards the medium directing outlet 415. Once the first heat exchange medium reaches the medium directing outlet 415, the first heat exchange medium is further directed to the outlet 150, from which the first heat exchange medium is discharged out of the heat exchanger 100.

In yet another embodiment of the present invention, the medium directing assembly posterior edge 275A may not engage the first side of the sub-chamber posterior wall 170. Instead, one or more of the lateral or vertical sides of the second longitudinal end of the medium directing assembly 220A may matingly engage one or more of the lateral or vertical panels comprising the cavity within the second sub-chamber 130.
Referring again to
In another embodiment of the present invention, as the first heat exchange medium is introduced in to the medium directing assembly 220A through the medium directing inlet 410A, the first heat exchange medium generally initially flows in a first line of flow following the longitudinal axial characteristic of the rectangular parallelepiped body of the medium directing assembly 220A, flowing in a pathway formed jointly by the medium directing assembly 220A and the first sub-chamber 125. In an embodiment of the present invention, the first longitudinal end of the medium directing assembly 220A is coupled inside the cavity provided in the first sub-chamber 125. As such, a first and a second lateral walls, as well as a bottom vertical wall of the first heat exchange medium pathway may be formed by the medium directing assembly 220A, while the top vertical wall of the medium pathway may generally be provided by the first sub-chamber top wall 175. As the first heat exchange medium travels further inwards within the pathway provided within the medium directing assembly 220A from the medium directing inlet 410A, the first heat exchange medium flowing initially in the first line of flow is directed to collide into the first planar surface of the medium directing panel 255A.
When the first heat exchange medium is directed to flow into the first planar surface of the medium directing panel 255A, the first heat exchange medium is disbursed on the first planar surface of the medium directing panel 255A, resulting in a second flow pattern that is divergent from the first line of flow. Furthermore, as the medium directing panel 255A is coupled within the medium directing assembly 220A at an angle in relation to the longitudinal axial characteristics of the medium directing assembly 220A, the first planar face of the medium directing panel 255A facing both the medium directing inlet 410A and the medium directing distribution outlet 420A, while laterally bound by the medium directing first side wall 240A and the medium directing second side wall 235A, the first heat exchange medium that was disbursed on the surface of the first planar surface of the medium directing panel 255A in the second flow pattern is further directed to flow out of the medium directing assembly 220A and into the main chamber 215 through the medium directing distribution outlet 420A, in a third line of flow. The third line of flow is generally perpendicular in relation to the plane established by the medium directing distribution outlet 420A.
As the third line of flow is generally perpendicular in relation to the initial line of flow established by the first line of flow, the first heat exchange medium generally travels vertically upwardly away from the medium directing assembly 220A. The first heat exchange medium is generally projected out of the medium directing assembly 220A in to the main chamber 215 through the medium directing distribution outlet 420A in a focused stream. As the third line of flow travels within the main chamber 215, the third line of flow terminates as the third line of flow reaches the lateral wall of the main chamber 215, comprising the first chamber wall 115 and the second chamber wall 120, within a perimeter of the lateral wall of the main chamber 215 vertically in line with the medium distribution outlet 410A. As the third line of flow contacts the lateral wall of the main chamber 215, the third line of flow terminates and generally transitions the flow of the first heat exchange medium into a pair of fourth line of flow within the main chamber 215.
The pair of fourth line of flow within the main chamber 215 for the first heat exchange medium are divergent lateral flows within the main chamber 215. The first fourth line of flow travels from generally the top vertical area of the main chamber 215 where the third line of flow terminates, traveling in the flow space provided between the lateral wall of the main chamber 215, comprising the first chamber wall 115 and the second chamber wall 120, and the medium directing first side wall 240A. The second fourth line of flow travels from generally the top vertical area of the main chamber 215 where the third line of flow terminates, traveling in the flow space provided between the lateral wall of the main chamber 215, comprising the first chamber wall 115 and the second chamber wall 120, and the medium directing second side wall 235A. The pair of fourth line of flow are generally directed to travel to an area vertically generally below the medium directing collecting inlet 425, at which point the pair of fourth line of flow collide in to each other and merge into a singular flow.
The merging of the pair of fourth line of flow terminates the pair of fourth line of flow and transition the heat exchange medium flow into a fifth line of flow, wherein the fifth line of flow is generally vertically perpendicular with respect to the plane generally established by the opening of the medium directing collecting inlet 425. In the fifth line of flow, the first heat exchange medium is discharged out of the main chamber 215 and introduced back into the medium directing assembly 220A through the medium directing collecting inlet 425, in a focused stream. As the fifth line of flow travels further into the medium directing assembly 220A, the first heat exchange medium is directed to collide with the second planar surface of the medium directing panel 255A, wherein the first heat exchange medium disburses on the surface of the second planar side of the medium directing panel 255A, initiating a sixth flow pattern. As the second planar surface of the medium directing panel 255A faces at an angle the medium directing collecting inlet 425 and the medium directing outlet 415A, the first heat exchange medium that was disbursed on the surface of the second side of the medium directing panel 255A in a sixth flow pattern is further directed to flow in a seventh line of flow following the longitudinal axial characteristics of the medium directing assembly 220A. As the first heat exchange medium flows within the medium directing assembly 220A in a seventh line of flow, the first heat exchange medium is directed to flow towards the medium directing outlet 415. Once the first heat exchange medium reaches the medium directing outlet 415, the first heat exchange medium is discharged out of the heat exchanger 100 out of the outlet 150.
