This application claims priority of Taiwanese Invention Patent Application No. 111109259, filed on Mar. 14, 2022.
The disclosure relates to a cooling device, and more particularly to a heat exchange device and a heat exchange system having the same.
Referring to
High temperature gas is introduced into the barrel 11 through the inlet 121 of one of the end caps 12, and flows out of the barrel 11 through the outlet 122 of the other one of the end caps 12. Similarly, low temperature gas is introduced into the barrel 11 through the inlet 121 of the other one of the end caps 12, and flows out of the barrel 11 through the outlet 122 of the one of the end caps 12. The high temperature gas mixes with the low temperature gas in the barrel 11 at an area near an open end 131 of the guiding tube member 13 so that the temperature of the high temperature gas flowing out of the outlets 122 is reduced.
Although the high temperature gas can be cooled down after being mixed with the low temperature gas, the degree of temperature reduction still depends on the amount of the low temperature gas introduced into the heat exchanger 1 and cannot be controlled since a dimension of the open end 131 is not adjustable.
Therefore, an object of the disclosure is to provide a heat exchange device and a heat exchange system capable of alleviating at least the drawback of the conventional heat exchanger.

The cap unit 3 includes two end caps 31 (i.e., upper and lower end caps 31). The end caps 31 are detachably and respectively connected to the end portions 21 of the barrel member 2. Each of the end caps 31 has an inner tube body 312 extending along the axis (X) and defining a tube defined channel 311 therein, and an outer tube body 314 surrounding the inner tube body 312 and cooperating with the inner tube body 312 to define an annular channel 313 therebetween. The outer tube body 314 of each of the end caps 31 has two annular portions 315 spaced apart from each other. In this embodiment, the annular portions 315 of each of the end caps 31 are diametrically opposite to each other and each of the annular portions 315 defines an opening 316. For each of the end caps 31, one of the openings 316 is in fluid communication with the tube defined channel 311, and the other one of the openings 316 is in fluid communication with the annular channel 313. In this embodiment, the tube defined channel 311 is not in fluid communication with the annular channel 313.
It should be noted that the outer tube body 314 of the upper end cap 31 which is connected to the condensing unit 6 defines a heat absorbing path 317 that is in spatial communication with the first flow channel, and that is adapted to permit the fluid to flow therethrough. The cap unit 3 further includes a mounting seat 318 connected to the outer tube body 314 of the lower end cap 31.

The electric unit 7 is mounted to the lower end cap 31 and includes a motor 71 that is connected to the mounting seat 318, an internal threaded sleeve 72 that is driven by the motor 71 to rotate, a connecting shaft 73 that is rotatably inserted into the mounting seat 318 and that interconnects the internal threaded sleeve 72 and the motor 71 so as to drive the internal threaded sleeve 72 to rotate, and an external threaded shaft 74 that threadedly engages and is driven by the internal threaded sleeve 72 to move along the axis (X) when the internal threaded sleeve 72 is rotated, and that is connected to and co-movable with the outer conduit 415 of the lower conduit member 41 such that a portion of the one of the conduit members 41 is movable relative to the other one of the conduit members 41 along the axis (X) to adjust a dimension of the gap 40 along the axis (X). In this embodiment, the electric unit 7 includes a pin 75 extending into and interconnecting the external threaded shaft 74 and the outer conduit 415.
It is worth noting that the fluid may be liquid, gas, mixtures of liquid and gas, mixtures of liquid and particles, mixtures of gas and particles, or mixtures of particles, liquid and gas. An advantage of employing mixtures of liquid and gas in form of the fluid resides in that a flow velocity of the fluid is relatively high.
In addition, in this embodiment, the barrel member 2, the end caps 31, the conduit members 41, the annular vortex generating member 5, and the heat dissipating module 62 are made of aluminum or other metal materials having a relatively high thermal conductivity, e.g., cooper.

In this way, the heat dissipating plates 612 of the cooling chip modules 61 dissipate heat outwardly of the heat exchange devices 6. In this embodiment, the heat dissipated by the heat dissipating plates 612 is absorbed by the fluid flowing through the heat dissipating paths 621 so as to achieve a cooling effect.
As shown in
When the fluid (indicated by solid arrows shown in
As such, the fluid in the second flow channel will perform heat exchange with the heat absorbing plate 611, the end caps 31, and the inner sets of the fins 413 of the heat exchanger 4. In a case that the fluid indicated by the solid arrows has a relatively low temperature, the temperature of the fluid in the second flow channel can be further reduced. On the other hand, in a case that the fluid indicated by the solid arrows has a relatively high temperature, the purpose of cooling can also be achieved. Moreover, it is important to note that the fluids in the first and second flow channels can be mixed by virtue of the vortex so as to adjust the temperature of the fluids, and a flow velocity of the fluid in the first flow channel is increased because of the increased amount of fluid flowing therein, thereby achieving the purpose of quick and significant cooling.
It is worth noting that, since the temperature of the fluid can be significantly reduced by using this embodiment, in a case where the fluid is gas, the majority of the gas will be condensed into liquid so that humidity of the gas can be reduced.

It should be noted that the connection among the heat exchange devices and the connecting device 8 of the present disclosure is not limited to the examples shown in
Thus, the heat exchange system of the present disclosure can be widely applied in the field of cooling, filtration, or processing, and can be connected to a vacuum machine (not shown) or a mold unit (not shown) if desired. In the case that the heat exchange system is applied in a machining process, e.g., vacuum extrusion, vacuum forging, vacuum casting, or vacuum injection, in addition to reducing of the temperature of the fluid or the mold unit, the heat exchange system of the present disclosure can also condense the fluid in the form of gas into liquid so that dryness and cleanliness of the fluid is enhanced, and thus the quality of products being processed is improved.
Through the above description, the advantages of the embodiment can be summarized as follows:
First, the dimension of the gap 40 can be easily adjusted by the motor 71 using electric power, which is labor-saving, and is easy to use.
Second, by virtue of the design of the condensing unit 6, the heat dissipating plate 612 is not in contact with the end cap 31 and the barrel member 2 and thus quick and significant temperature reduction can be achieved.
Third, the present disclosure can be modularized to be widely applied in the field of cooling, filtration, or machining. Furthermore, the effect of reducing the temperature of the fluid can be achieved, and the cleanliness and dryness of the fluid is enhanced, so that the quality of the products being processed is improved.
