The present invention relates to a water-cooling type condenser configured to cool a refrigerant by exchanging heat between cooling water and the refrigerant flowing along an inner portion thereof and including a gas-liquid separator separating a gas-phase refrigerant and a liquid-phase refrigerant from each other and integrally formed.
A heat exchanger is a device that absorbs heat from one side and dissipates the absorbed heat to the other side between two environments having a temperature difference, and acts as a cooling system in a case where it absorbs heat of the interior and dissipates the absorbed heat to the exterior and acts as a heating system when it absorbs heat of the exterior and dissipates the absorbed heat to the interior. The cooling system basically includes an evaporator absorbing heat from the surrounding, a compressor compressing a heat exchange medium, a condenser dissipating heat to the surrounding, and an expansion valve expanding the heat exchange medium.
In a cooling device, an actual cooling action is generated by an evaporator in which a liquid-phase heat exchange medium is vaporized by absorbing an amount of heat corresponding to heat of vaporization from the surrounding. In addition, a gas-phase heat exchange medium introduced from the evaporator into a compressor is compressed at a high temperature and a high pressure in the compressor, heat of liquefaction is dissipated to the surrounding in a process in which the compressed gas-phase heat exchange medium is liquefied while passing through the condenser, the liquefied heat exchange medium passes through an expansion valve to become a low-temperature and low-pressure wet saturated steam state, and is then introduced again into the evaporator to be vaporized, thereby forming a cycle.
Here, the condenser may be divided into an air-cooling type condenser cooling a refrigerant by exchanging heat with air and a water-cooling type condenser cooling a refrigerant by exchanging heat with cooling water, and a conventional water-cooling condenser of the air-cooling type condenser and the water-cooling type condenser is illustrated in

However, the gas-liquid separator 20 is configured so that the refrigerant communicates with the core part 10 through a connection pipe 15. Accordingly, pressure loss of the refrigerant increases, and there is a difficulty in manufacturing the water-cooling type condenser in a case where a shape of the connection pipe is complicated. In addition, since the gas-liquid separator 20 is formed in a structure in which it is coupled to the core part 10 using separate fixing brackets 30 or the like in order to be firmly fixed to the core part 10, the structure becomes complicated and the number of components is increased, which is disadvantageous in manufacturing the water-cooling type condenser.
An object of the present invention is to provide a water-cooling type condenser in which a core part in which a fluid channel through which a refrigerant flows and a fluid channel through which cooling water flows are formed and a gas-liquid separator which is coupled to the core part, into which the refrigerant is introduced, and which is configured to separate the introduced refrigerant into a liquid-phase refrigerant and a gas-phase refrigerant and discharge only the liquid refrigerant are formed integrally with each other and the gas-liquid separator may be connected to the core part so that the refrigerant communicates with the core part while being coupled and fixed to the core part.

In addition, the first communication part and the second communication part of the end plate may be formed to protrude toward the gas-liquid separator.
In addition, the end plate may be a clad member of which a surface in contact with the core part is formed as a clad surface, and inner circumferential surfaces of the first communication part and the second communication part may be formed as a clad surface and be joined to the penetration connector and the non-penetration connector.
In addition, the gas-liquid separator may be a clad member having an outer circumferential surface formed as a clad surface, and the penetration connector and non-penetration connector may be joined to the outer circumferential surface of the gas-liquid separator.
In addition, the penetration connector and the non-penetration connector may include, respectively, step parts formed between both insertion parts thereof so as to protrude in an outer diameter direction.
In addition, both side surfaces of the step parts of the penetration connector and the non-penetration connector may be formed asymmetrically, one side surfaces of the step parts may be formed as flat surfaces so as to correspond to a shape of a surface of the end plate with which the one side surfaces of the step parts are in contact, and the other side surfaces of the step parts may be formed as arc-shaped curved surfaces so as to correspond to a shape of a surface of the gas-liquid separator with which the other side surfaces of the step parts are in contact.
In addition, one or more of the penetration connector and the non-penetration connector may include seating grooves concavely formed in side surfaces of the step parts facing the gas-liquid separator, and clad rings formed of a clad material may be inserted into the seating grooves.

As illustrated in
The core part 100 may be formed by stacking a plurality of plates, and refrigerant fluid channels and cooling water fluid channels may be formed by stacking the plurality of plates. As an example, the core part 100 may include a plurality of first plates 110 and a plurality of second plates 120, and may be formed in a shape in which the first plates 110 and the second plates 120 are alternately stacked. In addition, the refrigerant fluid channels and the cooling water fluid channels may be alternately formed so that a refrigerant and cooling water easily exchange heat with each other, by stacking the first plates 110 and the second plates 120. Here, the first plates 110 and the second plates 120 may include side parts of which peripheral portions are bent to one side, and the side portions of the first and second plates may be in close contact with each other. In addition, the first and second plates may be formed of double-sided clad members, such that side surfaces of the first and second plates may be joined to each other by brazing after the first plates 110 and the second plates 120 are alternately stacked. In addition, a cup part may be formed in the first plate 110 by protruding a periphery of a through hole penetrating through both surfaces of the first plate 110 toward the second plate 120, and the cup part of the first plate 110 may be joined to the second plate by brazing to form a fluid channel. In addition, a refrigerant inlet 130 through which the refrigerant is introduced may be formed at one side of the core part 100 and a refrigerant outlet 140 may be formed at the other side of the core part 100. In addition, an inlet pipe through which the cooling water is introduced and an outlet pipe may be formed in the core part 100, and in the core part 100, the cooling water fluid channel may be divided into two portions, such that two inlet pipes and two outlet pipes may be formed. In addition, the core part 100 may be formed in various shapes.
The end plate 200 may be coupled to the core part 100, and may be coupled to a surface of the core part 100 in a direction in which the first plates 110 and the second plates 120 are stacked. In this case, the end plate 200 may be formed of a clad member of which a surface in contact with the core part 100 is a clad surface, such that the end plate 200 may be joined and coupled to the core part 100 by brazing. In addition, a first communication part 210 corresponding to and communicating with the refrigerant outlet 140 of the core part 100 may be formed in the end plate 200 so as to penetrate through both surfaces of the end plate 200, and a second communication part 220 may be formed at a position spaced apart from the first communication part 210 above the first communication part 210 so as to penetrate through both surfaces of the end plate 200. In addition, the end plate 200 may be formed of a plate material thicker than the first plate 110 and the second plate 120 constituting the core part 100, such that structural rigidity of the core part 100 may be improved by the end plate 200. In addition, the first communication part 210 and the second communication part 220 of the end plate 200 may be formed to protrude from peripheral portions of openings penetrating through both surfaces of the end plate 200 toward the gas-liquid separator 300, respectively. In this case, the first communication part 210 and the second communication part 220 of the end plate 200 may be formed to protrude from the peripheral portions of the openings toward the gas-liquid separator 300 by pressing a single clad member of which a surface in contact with the core part 100 is a clad surface, and accordingly, an inner circumferential surface of the first communicating part 210 and an inner circumferential surface of the second communicating part 220 may be the clad surface.
The gas-liquid separator 300 may be disposed to be spaced apart from the end plate 200 by a predetermined distance, and may serve to separate the refrigerant introduced into a refrigerant inlet 320 formed at one side thereof into a liquid-phase refrigerant and a gas-phase refrigerant and discharge only the liquid-phase refrigerant through a refrigerant outlet 330 formed at the other side thereof. In addition, the gas-liquid separator 300 may have the refrigerant inlet 320 formed at a lower side of one side thereof, and may have a coupling hole 310 formed at an upper side thereof and penetrating through both surfaces of the gas-liquid separator 300. In addition, the gas-liquid separator 300 may be formed of a clad member having an outer circumferential surface formed as a clad surface.
The penetration connector 400 may be formed in a shape in which a step part 420 protrudes from a central portion of a pipe in an outer diameter direction, and insertion parts 410 may be formed on both sides of the step part 420. In addition, a communication hole 401 penetrating through both insertion parts 410 may be formed in the penetration connector 400. One insertion part 410 of the penetration connector 400 may be inserted into the first communication part 210 of the end plate 200, and the other insertion part 410 of the penetration connector 400 may be inserted into the refrigerant inlet 320 of the gas-liquid separator 300. In addition, after the penetration connector 400 is assembled with the end plate 200 and the gas-liquid separator 300, surfaces of the penetration connector 400 in contact with the end plate 200 and the gas-liquid separator 300 may be joined to the end plate 200 and the gas-liquid separator 300 by brazing. Thus, the refrigerant fluid channel of the core part 100 and a refrigerant fluid channel of the gas-liquid separator 300 may communicate with each other by the penetration connector 400, and at the same time, a lower side of the gas-liquid separator 300 may be coupled to and fixed to the end plate 200 coupled to the core part 100 by the penetration connector 400.
The non-penetration connector 500 may be formed in a shape in which a step part 520 protrudes from a central portion of a pipe in an outer diameter direction, and insertion parts 510 may be formed on both sides of the step part 520. In addition, the non-penetration connector 500 may be formed in a shape in which a space between both insertion parts 510 is blocked by a blocking part 530. One insertion part 510 of the non-penetration connector 500 may be inserted into the second communication part 220 of the end plate 200, and the other insertion part 510 of the non-penetration connector 500 may be inserted into the coupling hole 310 of the gas-liquid separator 300. In addition, after the non-penetration connector 500 is assembled with the end plate 200 and the gas-liquid separator 300, surfaces of the non-penetration connector 500 in contact with the end plate 200 and the gas-liquid separator 300 may be joined to the end plate 200 and the gas-liquid separator 300 by brazing. Thus, an upper side of the gas-liquid separator 300 may be coupled and fixed to the end plate 200 coupled to the core part 100 by the non-penetration connector 500.
Accordingly, the water-cooling type condenser according to the present invention may decrease pressure loss of the refrigerant and have a simple structure and a compact configuration because it is possible to firmly fix the gas-liquid separator to the core part while allowing the refrigerant fluid channels of the gas-liquid separator and the core part to communicate with each other.
In addition, the water-cooling type condenser according to the present invention may be formed without a separate bracket for connecting and fixing the gas-liquid separator to the end plate because the gas-liquid separator is coupled and fixed to the end plate coupled to the core part by the penetration connector and the non-penetration connector.
In addition, both side surfaces of the step parts 420 and 520 of the penetration connector 400 and the non-penetration connector 500 may be formed asymmetrically, one side surfaces of the step parts 420 and 520 may be formed as flat surfaces so as to correspond to a shape of a surface of the end plate 200 with which the one side surfaces of the step parts 420 and 520 are in contact, and the other side surfaces of the step parts 420 and 520 may be formed as arc-shaped curved surfaces so as to correspond to a shape of a surface of the gas-liquid separator 300 with which the other side surfaces of the step parts 420 and 520 are in contact. That is, one side surfaces of the step parts 420 and 520 of the penetration connector 400 and the non-penetration connector 500 may be formed as the flat surfaces and be in contact with the entire side surface of the first communication part 210 or the second communication part 220 of the end plate 200 that one side surfaces of the step parts 420 and 520 face. In addition, the other side surfaces of the step parts 420 and 520 of the penetration connector 400 and the non-penetration connector 500 may be formed as the arc-shaped curved surfaces and be in contact with an outer circumferential surface of the coupling hole 310 or the refrigerant inlet 320 of the gas-liquid separator 300 that the other side surfaces of the step parts 420 and 520 face. Thus, the penetration connector 400 and the non-penetration connector 500 may be joined to the end plate 200 and the gas-liquid separator 300 in a state in which they are in close contact with the end plate 200 and the gas-liquid separator 300, and areas in which the penetration connector 400 and the non-penetration connector 500 are joined to the end plate 200 and the gas-liquid separator 300 may be great, such that a coupling force of the penetration connector 400 and the non-penetration connector 500 to the end plate 200 and the gas-liquid separator 300 may be improved.
In addition, outer circumferential surfaces of both insertion parts 410 of the penetration connector 400 may be formed as a clad surface. That is, the penetration connector 400 may be formed by using a pipe having an outer circumferential surface formed as a clad surface and fitting and coupling the step part into a central portion of an outer circumferential surface of the pipe. Accordingly, since the outer circumferential surfaces of the both insertion parts 410 of the penetration connector 400 becomes the clad surface, even though the inner circumferential surface of the first communication part 210 of the end plate 200 and the outer circumferential surface of the gas-liquid separator 300 are not clad surfaces, the insertion parts 410 of the penetration connector 400 may be easily joined to the inner circumferential surface of the first communication part 210 of the end plate 200 and the refrigerant inlet 320 of the gas-liquid separator 300 by brazing.
In addition, in the non-penetration connector 500, both insertion parts 510, the step part 520, and the blocking part 530 blocking the space between the both insertion parts 510 may be formed integrally with each other by cutting a material having a block or rod shape. That is, the non-penetration connector 500 includes the blocking part 530 blocking the space between both insertion parts 510 unlike the penetration connector 400, and may thus be formed by cutting the material having the rod shape as an example.
In addition, the non-penetration connector 500 may include seating grooves 540 concavely formed in the side surface of the step part 520 facing the gas-liquid separator 300, and clad rings 550 formed of a clad material may be inserted into the seating grooves 540. Thus, when brazing is performed in a state in which the insertion part 510 of the non-penetration connector 500 is inserted into and assembled with the coupling hole 310 of the gas-liquid separator 300, the clad rings 550 are melted, such that the non-penetration connector 500 may be joined to the coupling hole 310 of the gas-liquid separator 300 and an outer circumferential surface of its main surface. That is, since it is difficult for outer circumferential surfaces of the insertion parts 510 to be formed as a clad surface due to a structure of the non-penetration connector 500, as described above, the seating grooves 540 may be formed on the side surface of the step part 520, and the clad rings 550 may be inserted into the seating grooves 540 to allow the non-penetration connector 500 to be easily joined to the gas-liquid separator 300 by brazing. In addition, similar to the non-penetration connector 500, also in the penetration connector 400, seating grooves may be concavely formed in the side surface of the step part 420 facing the gas-liquid separator 300 and clad rings formed of a clad material may be inserted into the seating grooves to allow the penetration connector 400 to be easily joined to the gas-liquid separator 300 by brazing even though the outer circumferential surface of the insertion part 410 is not a clad surface.
In addition, the penetration connector 400 and the non-penetration connector 500 may be formed to have the same external shape except whether or not inner portions thereof are in a penetration shape. That is, the penetration connector 400 and the non-penetration connector 500 may be formed to have the same appearance except for whether or not fluid channels penetrating through the inner portions of the penetration connector 400 and the non-penetration connector 500 are formed on both sides of the penetration connector 400 and the non-penetration connector 500.
The present invention is not limited to the embodiments described above, and may be applied to various fields. In addition, the present invention may be variously modified by those skilled in the art to which the present invention pertains without departing from the gist of the present invention claimed in the claims.
