When the second heat exchange module is provided with a heat exchange groove, the opening of the heat exchange groove faces the first heat exchange module, and the heat exchange groove and the outer wall of the first heat exchange module cooperate to form a fourth heat exchange channel. When both the first heat exchange module and the second heat exchange module are provided with heat exchange grooves, the openings of the two heat exchange grooves are arranged opposite to each other, and the two heat exchange grooves cooperate to form a fourth heat exchange channel.

[0030] In the technical field of the thermal management system of new energy vehicles, heat exchange between media at different temperatures is usually involved. And generally, the existing thermal management system realizes heat exchange of more media by increasing the number of heat exchangers. However, with such a setting, the volume of the heat exchanger is greatly increased, which is not conducive to the integrated design of the heat exchanger.

[0031] Please refer to Figures 1 - 6, in order to solve the problems of the large volume and low integration degree of the existing heat exchangers, the present application provides an integrated heat exchange device. The integrated heat exchange device includes a first heat exchange part 100 and a second heat exchange part 200. The first heat exchange part 100 is provided with a first heat exchange channel 110 and a second heat exchange channel 120. The second heat exchange part 200 is provided with a third heat exchange channel 220 and a fourth heat exchange channel 230. The first medium can enter the first heat exchange part 100 through the first heat exchange channel 110, and the first medium can complete heat exchange with the second medium entering the second heat exchange channel 120 in the first heat exchange part 100. The first heat exchange channel 110 is communicated with the fourth heat exchange channel 230. The first medium can enter the fourth heat exchange channel 230 from the first heat exchange channel 110 and mix with the fourth medium in the fourth heat exchange channel 230, and the first medium and the fourth medium in the fourth heat exchange channel 230 can complete heat exchange with the third medium entering the third heat exchange channel 220 in the second heat exchange part 200.

[0032] In this way, by providing two heat exchange parts (the first heat exchange part 100 and the second heat exchange part 200), three heat exchanges among four media (the first medium, the second medium, the third medium and the fourth medium) are realized. Specifically, the first heat exchange between the first medium and the second medium in the first heat exchange part 100, the second heat exchange between the first medium and the third medium in the second heat exchange part 200, and the third heat exchange between the fourth medium and the third medium in the second heat exchange part 200. Compared with the prior art that at least three heat exchangers are required to meet the three heat exchanges of four media, the integrated heat exchange device provided by the present application has a smaller volume and higher integration degree, effectively solving the problems of the large volume and low integration degree of the existing heat exchangers.

[0033] In an embodiment, as Figure 1 and Figure 2 shown, the first heat exchange part 100 includes a throttling element 130 and a first heat exchanger 140. The high-temperature and high-pressure first medium can become a low-temperature and low-pressure state through the throttling element 130, and the low-temperature and low-pressure first medium can enter the first heat exchanger 140 through the first heat exchange channel 110 to absorb the heat of the second medium entering the first heat exchanger 140 through the second heat exchange channel 120.

[0034] At this time, the first heat exchanger 140 serves as an evaporator, and the first medium absorbs heat through a phase change within the first heat exchanger 140. That is, the first medium changes from a low-temperature and low-pressure liquid state to a low-temperature and low-pressure gaseous state. It should be noted that during the phase change process, the temperature of the first medium hardly changes. Moreover, the gaseous first medium will ultimately enter the compressor and, after being processed by the compressor, return to a high-temperature and high-pressure state, thus initiating the next cycle of the first medium. However, before the first medium enters the compressor, it may be in a certain degree of gas-liquid mixed form due to insufficient phase change, which may cause liquid slugging in the compressor and further damage the compressor.

[0035] To avoid liquid slugging in the compressor, in one embodiment, as Figure 5 shown, one of the first heat exchange part 100 and the second heat exchange part 200 is provided with a flow splitting channel 210 that respectively communicates with the first heat exchange channel 110 and the third heat exchange channel 220. A part of the high-temperature and high-pressure heat exchange medium can enter the first heat exchange channel 110 through the flow splitting channel 210 to form the first medium, and another part of the high-temperature and high-pressure heat exchange medium can enter the third heat exchange channel 220 through the flow splitting channel 210 to form the third medium.

[0036] In this way, the first medium in the fourth heat exchange channel 230 can complete heat exchange with the third medium entering the third heat exchange channel 220 within the second heat exchange part 200. That is, through the heating effect of the high-temperature and high-pressure third medium, the liquid first medium can be completely vaporized, thus effectively avoiding damage to the compressor caused by the liquid first medium entering the compressor and resulting in liquid slugging.

[0037] It should be noted that generally, the fourth medium in the fourth heat exchange channel 230 comes from other evaporators. Therefore, similarly, through the heating effect of the high-temperature and high-pressure third medium, the liquid fourth medium can be completely vaporized, thus effectively avoiding damage to the compressor caused by the liquid fourth medium entering the compressor and resulting in liquid slugging.

[0038] Specifically, in one embodiment, the throttling element 130 is an electronic expansion valve.

[0039] Furthermore, in one embodiment, as Figure 1 、 Figure 2 and Figure 7 shown, the first heat exchange part 100 further includes a mounting block 150, and the throttling element 130 is connected to the first heat exchanger 140 through the mounting block 150.

[0040] Even further, in one embodiment, as Figure 1 、 Figure 2 and Figure 7As shown, the mounting block 150 is provided with a first groove 151, and a throttling through-hole 152 is provided on the side wall of the first groove 151. The high-temperature and high-pressure first medium enters the throttling element 130 through the throttling through-hole 152.

[0041] In one embodiment, as Figure 1 and Figure 2 shown, the second heat exchange part 200 and the throttling element 130 are respectively arranged at two opposite ends of the first heat exchanger 140.

[0042] In this way, it is beneficial to reduce the assembly difficulty of the integrated heat exchange device and facilitate the installation of the integrated heat exchange device in the thermal management system.

[0043] In the prior art, the heat exchange between two media is usually realized through a plate heat exchanger or a concentric circle heat exchanger. Among them, after a large amount of heat release by the high-temperature and high-pressure third medium, the degree of undercooling will further increase. And at this time, the liquid third medium will settle under the action of gravity below the third heat exchange channel 220. In this way, the heat exchange effect of the fourth medium located above the third heat exchange channel 220 in the fourth heat exchange channel 230 will become worse, that is, the heat exchange uniformity of the fourth medium in the fourth heat exchange channel 230 will become worse.

[0044] To solve the problem of the poor heat exchange uniformity of the fourth medium in the fourth heat exchange channel 230, as Figures 2 - 6 shown, in one embodiment, the third heat exchange channel 220 is spirally wound around the outer periphery of the fourth heat exchange channel 230.

[0045] With this setting, even if the liquid third medium settles under the action of gravity, as long as the third medium continues to flow in the third heat exchange channel 220, the third medium can still make a 360-degree detour around the outer periphery of the fourth heat exchange channel 230 through the spiral third heat exchange channel 220. That is, it can ensure that the fourth medium still has a good heat exchange effect in the 360-degree circumferential direction, thereby improving the heat exchange uniformity of the fourth medium, and further improving the heat exchange performance of the integrated heat exchanger.

[0046] Furthermore, with this setting, the heat exchange amount of the third medium can also be controlled by setting the number of turns of the third heat exchange channel 220 wound around the fourth heat exchange channel 230, greatly improving the heat exchange accuracy of the integrated heat exchange device.

[0047] Furthermore, in one embodiment, as Figure 1 and Figure 2 shown, the second heat exchange part 200 includes a plurality of heat exchange modules, and the plurality of heat exchange modules are assembled to form the third heat exchange channel 220 and the fourth heat exchange channel 230.

[0048] In this way, the processing difficulty of the third heat exchange channel 220 and the fourth heat exchange channel 230 is greatly reduced, thereby improving the processing efficiency of the integrated heat exchange device.

[0049] Specifically, in one embodiment, as Figures 2 - 6 shown, the second heat exchange part 200 is provided with a first communication hole 221 and a second communication hole 222. The first communication hole 221 and the second communication hole 222 are distributed at opposite ends of the fourth heat exchange channel 230 along the width direction of the fourth heat exchange channel 230. A plurality of first communication holes 221 are spaced apart along the extending direction of the fourth heat exchange channel 230, and a plurality of second communication holes 222 are spaced apart along the extending direction of the fourth heat exchange channel 230. The second heat exchange part 200 is further provided with a first communication groove 223 and a second communication groove 224. The first communication groove 223 and the second communication groove 224 are distributed at opposite ends of the second heat exchange part 200 along the height direction of the fourth heat exchange channel 230. The first communication groove 223 and the second communication groove 224 respectively communicate with the relatively arranged first communication hole 221 and the second communication hole 222. The first communication groove 223, the first communication hole 221, the second communication groove 224 and the second communication hole 222 are connected end to end in sequence to form the third heat exchange channel 220.

[0050] With such a setting, the processing difficulty of the third heat exchange channel 220 is greatly reduced.

[0051] More specifically, in one embodiment, as Figures 2 - 6 shown, the second heat exchange part 200 includes a first heat exchange module 240 and a second heat exchange module 250. One or both of the first heat exchange module 240 and the second heat exchange module 250 are provided with heat exchange grooves 231. And when the first heat exchange module 240 is provided with heat exchange grooves 231, the openings of the heat exchange grooves 231 face the second heat exchange module 250, and the heat exchange grooves 231 and the outer wall of the second heat exchange module 250 cooperate to form the fourth heat exchange channel 230. When the second heat exchange module 250 is provided with heat exchange grooves 231, the openings of the heat exchange grooves 231 face the first heat exchange module 240, and the heat exchange grooves 231 and the outer wall of the first heat exchange module 240 cooperate to form the fourth heat exchange channel 230. When both the first heat exchange module 240 and the second heat exchange module 250 are provided with heat exchange grooves 231, the openings of the two heat exchange grooves 231 are arranged opposite to each other, and the two heat exchange grooves 231 cooperate to form the fourth heat exchange channel 230.

[0052] In this way, the processing difficulty of the fourth heat exchange channel 230 is greatly reduced.

[0053] Furthermore, in one embodiment, as Figure 2 and Figure 4 shown, the first communication groove 223 is arranged at one end of the first heat exchange module 240 close to the first heat exchange part 100, and the opening of the first communication groove 223 is in sealed cooperation with the outer wall of the first heat exchange part 100.

[0054] In this way, it is possible to prevent the third medium from leaking from the opening of the first communication groove 223.

[0055] In one embodiment, as Figure 2 and Figure 6 shown, the second heat exchange part 200 further includes a third heat exchange module 260. The second communication groove 224 is provided in the third heat exchange module 260, and the opening of the second communication groove 224 is in sealing cooperation with the outer wall of the second heat exchange module 250. The first communication hole 221 and the second communication hole 222 sequentially penetrate through the first heat exchange module 240 and the second heat exchange module 250 to communicate the first communication groove 223 and the second communication groove 224.

[0056] Through the modular design of the second heat exchange part 200, the processing difficulty of the third heat exchange channel 220 and the fourth heat exchange channel 230 in the second heat exchange part 200 is greatly reduced, and the processing efficiency of the second heat exchange module 250 and the entire integrated heat exchange device is greatly improved.

[0057] In one embodiment, as Figure 2 and Figure 4 shown, a connection groove 241 is provided at one end of the first heat exchange module 240 facing away from the second heat exchange module 250, and the first heat exchange channel 110 communicates with the fourth heat exchange channel 230 through the connection groove 241.

[0058] It should be noted that, in one embodiment, as Figure 2 shown, the first heat exchange module 240, the second heat exchange module 250, the third heat exchange module 260 and the first heat exchange part 100 are welded together.

[0059] As Figure 2 shown, the high-temperature and high-pressure first medium changes from the shunt channel 210 to a low-temperature and low-pressure state through the throttling and pressure-reducing action of the throttling element 130. After that, the first medium completes heat exchange with the second medium in the first heat exchanger 140, and the first medium partially or completely changes from liquid to gas by absorbing heat. Then, the gaseous first medium leaves the first heat exchange channel 110 of the first heat exchange part 100 and enters the fourth heat exchange channel 230 of the second heat exchange part 200, and the first medium mixes with the fourth medium in the fourth heat exchange channel 230. At the same time, the high-temperature and high-pressure third medium enters the third heat exchange channel 220 of the second heat exchange part 200 from the shunt channel 210, and under the heating of the third medium, the first medium and the fourth medium all absorb heat and change into gas. Finally, the first medium and the fourth medium enter the compressor through the fourth heat exchange channel outlet 233. The third medium enters the next electronic expansion valve through the third heat exchange channel outlet 225.

[0060] It should be noted that, as Figure 2As shown, the integrated heat exchange device further includes a connecting member 300. The connecting member 300 is provided at one end of the third heat exchange module 260 facing away from the second heat exchange module 250. Moreover, the fourth heat exchange channel inlet 232, the fourth heat exchange channel outlet 233, and the third heat exchange channel outlet 225 are all provided on the connecting member 300. And, two fixing members 400 are inserted at one end of the connecting member 300 away from the third heat exchange module 260, and the integrated heat exchange device is assembled to the thermal management system through the fixing members 400.

[0061] The present application also provides a thermal management system, which includes the integrated heat exchange device described in any one of the above embodiments.

[0062] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0063] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
