Description

[0002] In related technologies, vehicle air conditioners or heat pump air conditioning systems mainly use air-cooled condensers or water-cooled integrated condensers to exchange heat with refrigerants. The heat dissipation effect of the air-cooled condenser is low, and it is arranged side by side with a motor radiator, thereby increasing the resistance on the air side. It is necessary to dissipate heat by increasing the power of the electronic fan and the mass and cost of the module. The water-cooled integrated condenser exchanges heat with the refrigerant through a plate heat exchanger, which requires the addition of a plate heat exchanger, cooling pipelines, a control water valve, and other components.

DETAILED DESCRIPTION

[0041] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0042] In the present disclosure, the orientation words such as "upper, lower, high, low, top, bottom" used without the opposite description generally refer to the orientation of the corresponding components or structures in the direction of gravity. "Inner, outer" refers to the inner and outer of the corresponding component contour.

In addition, in the description referring to the drawings, the same marks in different drawings represent the same elements. The above definitions are only for the interpretation and explanation of the present disclosure, and should not be understood as a limitation of the present disclosure.

[0043] For ease of understanding, the specific structure and working principle of the heat exchange module of the present disclosure will be described in detail below with reference to the accompanying drawings. Figures 1 to 6 For ease of understanding, the specific structure and working principle of the heat exchange module of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0044] The present disclosure relates to a heat exchange module capable of adjusting different heat exchange amounts according to actual heat load, referring to Figure 1 and Figure 5 The heat exchange module of the present disclosure includes a mounting seat 1 capable of providing a mounting base for the structure in the heat exchange module, and an air-cooled heat dissipation assembly 3 connected to the mounting seat 1, including a first housing 33, a first heat dissipation pipe assembly 31 and a second heat dissipation pipe assembly 32. The first housing 33 has a first flow collection chamber 331 and a second flow collection chamber 332 isolated from each other, wherein the first flow collection chamber 331 is used to introduce cooling liquid, and the second flow collection chamber 332 is used to introduce air conditioner refrigerant. One end of the first heat dissipation pipe assembly 31 is connected to the first housing 33 and communicates with the first flow collection chamber 331, which is used for air-cooled heat dissipation of the cooling liquid. One end of the second heat dissipation pipe assembly 32 is also connected to the first housing 33 and communicates with the second flow collection chamber 332, which is used for air-cooled heat dissipation of the air conditioner refrigerant.

[0045] By providing the first housing 33, the cooling liquid and the air conditioner refrigerant can be first gathered into the first flow collection chamber 331 and the second flow collection chamber 332 respectively before entering the first heat dissipation pipe assembly 31 and the second heat dissipation pipe assembly 32, and then uniformly distributed, so that the cooling liquid and the air conditioner refrigerant can be evenly introduced into the first heat dissipation pipe assembly 31 and the second heat dissipation pipe assembly 32, avoiding the situation that some of the first heat dissipation pipe assembly 31 and the second heat dissipation pipe assembly 32 do not enter the liquid, and reducing the heat dissipation efficiency of the air-cooled heat dissipation assembly 3.

[0046] Compared with the prior art, the heat exchange module disclosed herein integrates an air-cooled radiator and a condenser. When in use, the coolant and the air-conditioning refrigerant can enter the first heat dissipation pipe assembly 31 and the second heat dissipation pipe assembly 32 respectively through the first collecting chamber 331 and the second collecting chamber 332 in the first shell 33 and dissipate heat synchronously by the heat dissipation air source 6. Compared with traditional heat exchange modules, it can have a more compact structure, reduce complex piping, achieve lower costs, and also have better heat dissipation efficiency.

[0047] In one embodiment of the present disclosure, see Figure 1 and Figure 2 The heat exchange module of the present disclosure also includes a liquid-cooled heat exchange tube assembly 2. A liquid-cooled chamber 11 capable of receiving a coolant is provided on the mounting base 1. The liquid-cooled heat exchange tube assembly 2 is capable of receiving an air conditioning refrigerant and is connected to the mounting base 1 and at least partially located within the liquid-cooled chamber 11. After entering the liquid-cooled heat exchange tube assembly 2, the air conditioning refrigerant can exchange heat with the coolant in the liquid-cooled chamber 11, thereby heating or cooling the air conditioning refrigerant.

[0048] In order to facilitate the subsequent air-cooling and heat dissipation of the coolant and air-conditioning refrigerant, the first collecting chamber 331 is also connected to the liquid-cooling chamber 11. The communication method can be to set a second coolant inlet 39 connected to the first collecting chamber 331 on the first shell 33, so that the first collecting chamber 331 is connected to the liquid-cooling chamber 11 through the second coolant inlet 39, and the second collecting chamber 332 is also connected to the liquid-cooling heat exchange tube assembly 2. The communication method can be to set a second refrigerant inlet 38 on the first shell 33, so that the second collecting chamber 332 is connected to the liquid-cooling heat exchange tube assembly 2 through the second refrigerant inlet 38.

[0049] When in use, the air-conditioning refrigerant will pass into the liquid-cooled heat exchange tube assembly 2 and exchange heat with the coolant in the liquid-cooling chamber 11, which can either lower the temperature of the air-conditioning refrigerant or increase the temperature of the air-conditioning refrigerant. After that, the air-conditioning refrigerant that has completed the heat exchange with the coolant will enter the second heat dissipation tube assembly 32 and be dissipated by the heat dissipation air source 6 (if the heat dissipation air source 6 is not needed for heat dissipation, the heat dissipation air source 6 can also be turned off), and finally flow out of the second heat dissipation tube assembly 32 for subsequent circulation.

[0050] The cooling liquid is first introduced into the liquid cooling chamber 11. The first cooling liquid inlet 12 and the first cooling liquid outlet 13 are arranged on the mounting base 1, so that the cooling liquid can flow into the liquid cooling chamber 11 through the first cooling liquid inlet 12, exchange heat with the liquid cooling heat exchange pipe assembly 2 in the liquid cooling chamber 11, and then flow out of the liquid cooling chamber 11 through the first cooling liquid outlet 13 to the first heat dissipation pipe assembly 31 for heat dissipation by the heat dissipation air source 6 (if the heat dissipation air source 6 is not needed for heat dissipation, the heat dissipation air source 6 can also be closed), and finally flows out of the first heat dissipation pipe assembly 31 for subsequent circulation. The heat dissipation air source 6 can be a fan device or other forms of air flow driving devices, which are not limited in the present disclosure.

[0051] In other embodiments, the liquid cooling heat exchange pipe assembly 2 can also be arranged in the first flow collecting chamber 331 and communicated with the second flow collecting chamber 332, so as to save the space occupied by the liquid cooling heat exchange pipe assembly 2 in other positions.

[0052] In an embodiment of the present disclosure, referring to Figure 1 and Figure 3 The liquid cooling heat exchange pipe assembly 2 comprises a heat exchange part 21 and a connecting part 22. The heat exchange part 21 is at least partially located in the liquid cooling chamber 11, and the first refrigerant inlet 211 and the first refrigerant outlet 212 are arranged on the heat exchange part 21. The air conditioner refrigerant can enter the heat exchange part 21 through the first refrigerant inlet 211, exchange heat with the cooling liquid in the liquid cooling chamber 11, and then flow out of the heat exchange part 21 through the first refrigerant outlet 212 to the second heat dissipation pipe assembly 32 of the air cooling heat dissipation assembly 3 for subsequent heat dissipation. The connecting part 22 can detachably connect the liquid cooling heat exchange pipe assembly 2 to the mounting base 1. The detachable connection can be achieved by structural clamping, direct bonding, or other detachable connection methods known to those skilled in the art, which will not be described in detail here.

[0053] The detachable connection between the liquid cooling heat exchange pipe assembly 2 and the mounting base 1 through the connecting part 22 can replace different models of liquid cooling heat exchange pipe assemblies 2 according to the actual heat load generated during use, so that the liquid cooling heat exchange pipe assembly 2 can reach the optimal level of system performance, avoid the problem of low heat exchange performance of the liquid cooling heat exchange pipe assembly 2 or excessive performance, and waste of the assembly. The air cooling heat dissipation assembly 3 in the heat exchange module of the present disclosure can also simultaneously dissipate heat for the air conditioner refrigerant and the cooling liquid, so that the structure of the heat exchange module of the present disclosure can be simplified, the production and manufacturing are facilitated, and the cost is low.

[0054] In an embodiment of the present disclosure, referring to Figure 1 and Figure 3The liquid cooling chamber 11 has an opening 111, the heat exchange part 21 can enter the liquid cooling chamber 11 through the opening 111, the connecting part 22 comprises a connecting plate 221 connected to the heat exchange part 21, when connecting the liquid cooling heat exchange pipe assembly 2, first put the part of the heat exchange part 21 that needs to be put into the liquid cooling chamber 11 into the liquid cooling chamber 11 through the opening 111, until the connecting plate 221 moves to the position of the opening 111, the opening 111 can be blocked by the connecting plate 221, then the connecting plate 221 is fixedly connected to the mounting seat 1 through the fastening bolt 222, and the detachable connection of the liquid cooling heat exchange pipe assembly 2 is completed, and when disassembling, only the fastening bolt 222 needs to be removed to complete the disassembly, the whole installation and disassembly process is relatively simple and convenient, and has good connection effect.

[0055] Of course, in some other embodiments, a stepped groove matched with the connecting plate 221 can also be arranged at the opening 111, so as to facilitate the butt joint of the connecting plate 221, and a sealing strip can also be arranged on the side of the connecting plate 221 facing the opening 111 to assist connection and sealing, which can be determined according to actual conditions, and the present disclosure does not limit this.

[0056] In an embodiment of the present disclosure, referring to Figure 1 and Figure 3 , the heat exchange part 21 comprises a first flow collector 223, a second flow collector 224 and a heat exchange pipe assembly 225. A first cavity 226 is formed in the inside of the first flow collector 223, a second cavity 227 is formed in the inside of the second flow collector 224, one end of the heat exchange pipe assembly 225 is connected with the first flow collector 223 and communicates with the first cavity 226, the other end is connected with the second flow collector 224 and communicates with the second cavity 227, and one of the first flow collector 223 and the second flow collector 224 is provided with a first refrigerant inlet 211, and the other is provided with a first refrigerant outlet 212.

[0057] Specifically, taking the first refrigerant inlet 211 arranged on the first flow collector 223 as an example, in use, the air conditioner refrigerant first enters the first cavity 226 in the first flow collector 223 through the first refrigerant inlet 211, is then dispersed into the heat exchange pipe assembly 225 to exchange heat with the cooling liquid in the liquid cooling chamber 11, and after the heat exchange is completed, flows into the second flow collector 224 and is gathered into the second cavity 227, and finally flows out into the air cooling heat dissipation assembly 3 through the first refrigerant outlet 212 on the second flow collector 224. By arranging the first flow collector 223 and the second flow collector 224, the air conditioner refrigerant can be gathered in the first flow collector 223 and the second flow collector 224 before heat exchange and air cooling, and then uniformly flows into the heat exchange pipe assembly 225 and the second heat dissipation pipe assembly 32, so as to improve the heat exchange and heat dissipation effect.

[0058] When installing, the heat exchange pipe assembly 225, and the part of the first and second collecting pieces 223 and 224 connected with the heat exchange pipe assembly 225 are put into the liquid cooling chamber 11, and the first and second collecting pieces 223 and 224 are arranged outside the liquid cooling chamber 11, so as to facilitate the inflow and outflow of the air conditioner refrigerant.

[0059] In an embodiment of the present disclosure, referring to Figure 1 and Figure 5 The air-cooled heat dissipation assembly 3 further comprises a second shell 34, the third and fourth collecting chambers 341 and 342 are formed in the second shell 34 and are isolated from each other, the second cooling liquid outlet 35 is arranged in the second shell 34 and communicates with the third collecting chamber 341, and the second refrigerant outlet 36 is arranged in the second shell 34 and communicates with the fourth collecting chamber 342, one end of the first heat dissipation pipe assembly 31 is connected to the second shell 34 and communicates with the third collecting chamber 341, and one end of the second heat dissipation pipe assembly 32 is connected to the second shell 34 and communicates with the fourth collecting chamber 342.

[0060] By arranging the second shell 34, the cooling liquid and the air conditioner refrigerant can be collected into the third and fourth collecting chambers 341 and 342 after being dispersed into the first and second heat dissipation pipe assemblies 31 and 32 and being air-cooled, so that the cooling liquid and the air conditioner refrigerant can be discharged from the heat exchange module through the second cooling liquid outlet 35 and the second refrigerant outlet 36 respectively for subsequent circulation and use.

[0061] In an embodiment of the present disclosure, referring to Figure 1 and Figure 5 The air-cooled heat dissipation assembly 3 further comprises a cooling liquid supplement port 37, which is arranged on the first shell 33 and communicates with the first collecting chamber 331, or is arranged on the second shell 34 and communicates with the third collecting chamber 341. By arranging the cooling liquid supplement port 37, the cooling liquid can be supplemented in the heat exchange module in time, so as to avoid the decline of the heat exchange effect on the air conditioner refrigerant due to the lack of the cooling liquid. In the embodiment, the cooling liquid supplement port 37 is arranged on the second shell 34 and communicates with the third collecting chamber 341, so that the cooling liquid can be prevented from flowing back to the liquid cooling chamber 11 through the first shell 33 and affecting the heat exchange effect of the liquid cooling chamber 11.

[0062] In an embodiment of the present disclosure, referring to Figure 5 and Figure 6In the first shell 33 and the second shell 34, a partition structure is arranged between the first flow collection chamber 331 and the second flow collection chamber 332 to separate the first flow collection chamber 331 and the second flow collection chamber 332, and another partition structure is arranged between the third flow collection chamber 341 and the fourth flow collection chamber 342 to separate the third flow collection chamber 341 and the fourth flow collection chamber 342.

[0063] Specifically, the partition structure includes a first partition 333 and a second partition 334, and the first partition 333 and the second partition 334 are arranged close to each other and are spaced apart, and the first shell 33 and the second shell 34 are further provided with a vent hole 335 in communication with the spaced positions of the first partition 333 and the second partition 334. By arranging the first partition 333 and the second partition 334, the inner cavity of the first shell 33 can be divided into the first flow collection chamber 331 and the second flow collection chamber 332, and the spaced part of the first partition 333 and the second partition 334, and the inner cavity of the second shell 34 can be divided into the third flow collection chamber 341 and the fourth flow collection chamber 342, and the spaced part of the first partition 333 and the second partition 334, to ensure the isolation between different flow collection chambers in the first shell 33 and the second shell 34. By arranging the vent hole 335 on the first shell 33 and the second shell 34, when the first shell 33, the second shell 34, the first partition 333 or the second partition 334 is damaged, the air conditioner refrigerant or the cooling liquid in the flow collection chamber can flow out through the vent hole 335, without internal leakage causing damage to the entire system. By flowing out of the liquid, the user can early identify the failure problem of the system, and reduce the loss.

[0064] In one embodiment of the present disclosure, referring to Figure 5 The first heat dissipation pipe assembly 31 and the second heat dissipation pipe assembly 32 form a flat plate-shaped heat sink, and the ratio of the heat dissipation area of the first heat dissipation pipe assembly 31 to the heat dissipation area of the second heat dissipation pipe assembly 32 is X, and the value of X is in the range of 2≤X≤4.

[0065] The cooling effect of the refrigerant after being cooled by the liquid cooling is greatly affected by the temperature of the cooling liquid. In order to reduce the influence of the high temperature of the cooling liquid on the heat dissipation performance of the air conditioner, the first heat dissipation pipe assembly 31 is in communication with the liquid cooling chamber 11 in the mounting seat 1 to cool the cooling liquid by air cooling, and the second heat dissipation pipe assembly 32 is connected with the liquid cooling heat exchange pipe assembly 2 to increase the second stage of air cooling for the refrigerant of the air conditioner, thereby further reducing the temperature of the refrigerant close to the ambient temperature, and achieving the cooling performance level of the air conditioner under normal ambient temperature. The heat exchange area of the liquid cooling heat exchange pipe assembly 2 can be adjusted according to the actual situation to achieve the optimal performance level of the liquid cooling heat exchange pipe assembly 2. Those skilled in the art can define the heat dissipation area of the first heat dissipation pipe assembly 31 according to the heat exchange area of the liquid cooling heat exchange pipe assembly 2. The heat dissipation area of the first heat dissipation pipe assembly 31 is in a positive correlation with the heat exchange area of the liquid cooling heat exchange pipe assembly 2.

[0066] The ratio of the heat dissipation area of the first heat dissipation pipe assembly 31 to the heat dissipation area of the second heat dissipation pipe assembly 32 is X, and the value of X is in the range of 2≤X≤4. The air cooling heat dissipation demand for the cooling liquid and the refrigerant of the air conditioner can be reasonably considered, so that the total area of the above-mentioned flat plate-shaped heat sink is controlled within a reasonable range, which is beneficial to realize the miniaturization of the heat exchange module and reduce the installation space. In some embodiments, the value of X can be any value between 2 and 4. Preferably, the value of X is in the range of 2.8≤X≤3.2.

[0067] When the heat exchange module of the present disclosure is used, the liquid cooling heat exchange pipe assembly 2 needs to be installed on the mounting seat 1 first, and then the air cooling heat dissipation assembly 3 is also installed on the mounting seat 1. The communication between different assembly chambers is shown in Figure 4 It can be directly connected by butt joint and provided with a sealing ring or other sealing structure for connection, or it can be connected by pipes, which can be determined according to the actual situation, and the present disclosure does not limit it.

[0068] After the connection is completed, the heat exchange module of the present disclosure can be used for cooling or heating the air conditioner refrigerant according to the needs. When the vehicle is driving on a normal road, it is a normal or high temperature environment, and the cooling liquid temperature is about 30-50℃, which is slightly higher than the ambient temperature. When the air conditioner refrigerant is compressed to work and reaches a high temperature and high pressure state, the temperature can generally reach 80-100℃. At this time, the air conditioner refrigerant needs to be cooled. During the cooling process, the air conditioner refrigerant first enters the first chamber 226 in the first manifold 223 through the first refrigerant inlet 211 on the liquid cooling heat exchange pipe assembly 2, and then is dispersed into the heat exchange pipe assembly 225 in the first chamber 226 and exchanges heat with the cooling liquid in the liquid cooling chamber 11. After the heat exchange is completed, it converges into the second chamber 227 in the second manifold 224, and enters the second manifold chamber 332 through the first refrigerant outlet 212 on the second manifold 224 and the second refrigerant inlet 38 on the first shell 33, and then enters the second heat dissipation pipe assembly 32 through the second manifold chamber 332 and is air-cooled by the heat dissipation air source 6. Finally, it converges into the fourth manifold chamber 342 in the second shell 34 and flows out of the heat exchange module to the subsequent cycle through the second refrigerant outlet 36.

[0069] When the vehicle is driving in a low temperature environment, for example, the ambient temperature is -7℃. Because the vehicle motor assembly generates heat during work, the cooling liquid for heat dissipation of the motor assembly can reach a higher temperature, for example, the cooling liquid temperature can reach 0-10℃. When the air conditioner refrigerant needs to be heated, the heating process is as follows: the air conditioner refrigerant first enters the first chamber 226 in the first manifold 223 through the first refrigerant inlet 211 on the liquid cooling heat exchange pipe assembly 2, and then is dispersed into the heat exchange pipe assembly 225 in the first chamber 226 and exchanges heat with the cooling liquid in the liquid cooling chamber 11 to increase the temperature. At this time, the air conditioner refrigerant no longer needs to be air-cooled for heat dissipation, and the AGS can be closed to stop the operation of the heat dissipation air source 6 to avoid the low-temperature wind from taking away the heat. Then, the heat-exchanged air conditioner refrigerant passes through the second manifold chamber 332, the fourth manifold chamber 342, and the second shell 34, and finally flows out of the heat exchange module to the subsequent cycle through the second refrigerant outlet 36.

[0070] The flow of the cooling liquid is as follows: the cooling liquid flows into the liquid cooling chamber 11 through the first cooling liquid inlet 12 on the mounting seat 1, exchanges heat with the liquid cooling heat exchange pipe assembly 2 in the liquid cooling chamber 11, and then flows into the first manifold chamber 331 through the first cooling liquid outlet 13 on the mounting seat 1 and the second cooling liquid inlet 39 on the first shell 33. Then, it enters the first heat dissipation pipe assembly 31 through the first manifold chamber 331 and is air-cooled by the heat dissipation air source 6. Finally, it converges into the third manifold chamber 341 in the second shell 34 and flows out of the heat exchange module to the subsequent cycle through the second cooling liquid outlet 35.
