[0037] like Figure 1-Figure 8 As shown, a heat exchanger 100 according to an embodiment of the present utility model includes: a shell 1, a heat exchange core 2 and an elastic member 3.

[0038] The shell 1 is provided with a cooling water inlet 111, a cooling water outlet 112, a refrigerant inlet 113 and a refrigerant outlet 114. The heat exchange core 2 is installed in the shell 1. The heat exchange core 2 includes an intermediate heat exchange member 21 and two end heat exchange members 23. The two end heat exchange members 23 are respectively connected to the two ends of the intermediate heat exchange member 21 and are plugged and matched with the intermediate heat exchange member 21.

The refrigerant at the refrigerant inlet 113 is suitable for flowing between the end refrigerant flow channels 24 of the two end heat exchangers 23 through the middle refrigerant flow channel 22 and flowing to the refrigerant outlet 114. The refrigerant in the middle refrigerant flow channel 22 is suitable for heat exchange with cooling water. The refrigerant inlet 113 and the refrigerant outlet 114 are both connected to the end refrigerant flow channel 24 of one of the two end heat exchangers 23, and the elastic member 3 is elastically pressed between the other of the two end heat exchangers 23 and the shell 1.

[0039] Among them, the heat exchanger 100 is arranged inside the vehicle. When the vehicle is in actual working state, the refrigerant with lower temperature can enter the heat exchanger 100 through the pipeline, and then exchange heat with the cooling water passed into the heat exchanger 100 through the heat exchange core 2 in the heat exchanger 100. Then, the cooling water with lower temperature can flow to the outside of the heat exchanger 100 to exchange heat with structures such as the vehicle battery, and then the vehicle battery and the vehicle's electric drive system can be cooled to ensure the reliability of vehicle operation. The heat exchanger 100 is provided with a cascade type and a parallel flow type. The cascade heat exchanger 100 can be used in an environment with lower operating pressure, and the parallel flow heat exchanger 100 can be used in an environment with higher operating pressure, thereby meeting different usage requirements and having a wider range of applications.

[0040] Specifically, the heat exchanger 100 is provided with a shell 1, which is arranged at the outermost side of the heat exchanger 100. The shell 1 can be set to an aluminum material, thereby improving the lightweight of the heat exchanger 100. The shell 1 can provide an installation space for the components inside the heat exchanger 100, and can provide support and protection for the components inside the heat exchanger 100, thereby ensuring the operational reliability of the heat exchanger 100.

[0041] The shell 1 is provided with a cooling water inlet 111 and a cooling water outlet 112, that is, cooling water with a higher temperature can enter the heat exchanger 100 through the cooling water inlet for heat exchange, thereby reducing the cooling water temperature, and the cooled cooling water can flow to the outside of the heat exchanger 100 through the cooling water outlet 112 to cool the vehicle battery and the vehicle's electric drive system, etc., to ensure the reliability of vehicle operation. The shell 1 is also provided with a refrigerant inlet 113 and a refrigerant outlet 114. The low-temperature refrigerant can enter the heat exchanger 100 through the refrigerant inlet 113 to exchange heat with the cooling water, thereby reducing the cooling water temperature. At this time, the refrigerant temperature rises, and the heated refrigerant can flow to the outside of the heat exchanger 100 through the refrigerant outlet 114.

[0042] Furthermore, the heat exchanger 100 is provided with a heat exchange core 2, which can be installed in the heat exchanger 100, and the heat exchange core 2 is provided with an intermediate heat exchanger 21 and an end heat exchanger 23, two end heat exchangers 23 are provided, the intermediate heat exchanger 21 is provided between the two end heat exchangers 23, and the two ends of the intermediate heat exchanger 21 are respectively plugged into and matched with the two end heat exchangers 23, thereby fixing the two end heat exchangers 23 and the intermediate heat exchanger 21 in fixed connection.

[0043] The heat exchange core 2 is provided with an inlet area 25 and an outlet area 26 that are spaced apart and distributed. The inlet area 25 and the outlet area 26 are connected, the cooling water inlet 111 is connected to the inlet area 25, and the cooling water outlet 112 is connected to the outlet area 26, that is, the cooling water can enter the inlet area 25 through the cooling water inlet 111, and then flow to the outlet area 26, and then flow out of the heat exchanger 100 through the cooling water outlet 112.

[0044] At the same time, the two end heat exchangers 23 are each provided with an end refrigerant flow channel 24, and the middle heat exchanger 21 is provided with a middle refrigerant flow channel 22. The end refrigerant flow channels 24 and the middle refrigerant flow channel 22 are connected, and the refrigerant can flow into the end refrigerant flow channels 24 through the refrigerant inlet 113, so as to flow between the two end refrigerant flow channels 24 through the middle refrigerant flow channel 22. The refrigerant after heat exchange can flow out of the heat exchanger 100 through the refrigerant outlet 114, and when the refrigerant flows to the middle refrigerant flow channel 22, it can exchange heat with the cooling water in the inlet area 25 and the outlet area 26. The refrigerant at the refrigerant inlet 113 is in a two-phase state, and when the refrigerant absorbs heat, the refrigerant at the refrigerant outlet 114 is in a gaseous state.

[0045] In addition, an elastic member 3 is also provided in the heat exchanger 100, and the elastic member 3 can be set as an elastic sheet, etc. The shell 1 is provided with a refrigerant inlet 113, and the refrigerant can enter the heat exchanger 100 through the refrigerant inlet 113 to exchange heat with the cooling water, and the refrigerant after heat exchange can flow to the outside of the heat exchanger 100 through the refrigerant outlet 114. The refrigerant inlet 113 and the refrigerant outlet 114 are both arranged near one of the two end heat exchangers 23, and the refrigerant inlet 113 and the refrigerant outlet 114 are both connected to the end refrigerant flow channel 24 of the end heat exchanger 23.

[0046] At the same time, the elastic member 3 can be arranged between the other end heat exchange member 23 of the two end heat exchange members 23 and the shell 1, and pressed between the end heat exchange member 23 and the shell 1, that is, the elastic member 3 is arranged between the end heat exchange member 23 and the shell 1 away from the connection between the inlet area 25 and the outlet area 26. When the heat exchanger 100 is installed, the elastic member 3 is in a compressed pre-tightened state between the end heat exchange member 23 and the shell 1. When a gap is generated between the end heat exchange member 23 and the inner end surface of the shell 1 due to welding or the like, the elastic member 3 can still be pressed against the end heat exchange member 23 and the inner end surface of the shell 1 respectively under the action of elastic force to close the gap between the end heat exchange member 23 and the inner end surface of the shell 1, thereby preventing cooling water that has not been fully heat exchanged from flowing through the gap, thereby improving the heat exchange effect of the heat exchange core 2, and further improving the heat exchange efficiency of the heat exchanger 100.

[0047] According to the heat exchanger 100 of the embodiment of the utility model, an elastic member 3 is provided between the end heat exchange member 23 and the shell 1 on the side away from the refrigerant inlet 113 and the refrigerant outlet 114, thereby closing the gap between the end heat exchange member 23 and the shell 1, avoiding cooling water bypass, and improving the heat exchange effect of the heat exchange core 2, thereby improving the heat exchange efficiency of the heat exchanger 100, achieving better use effect and wider application range.

[0048] In some embodiments, the shell 1 includes an upper cover 11, a side panel 12 and a bottom cover 13, the upper cover 11 and the bottom cover 13 are respectively connected to the upper and lower sides of the side panel 12, and an elastic member 3 is provided between at least one of the two end heat exchange components 23 and the inner wall of the side panel 12.

[0049] Specifically, Figure 3As shown, the heat exchanger 100 is provided with a shell 1, which can provide installation space for the components inside the heat exchanger 100 and provide support and protection for the components inside the heat exchanger 100, and the shell 1 is provided with an upper cover 11, a side panel 12 and a bottom cover 13, the side panel 12 is set as an annular plate structure, the upper cover 11 is connected to one side of the side panel 12, and the middle part of the upper cover 11 can protrude toward the side panel 12, so that the upper cover 11 can be interference fit with the side panel 12, the bottom cover 13 is connected to the other side of the side panel 12, and the middle part of the bottom cover 13 can also protrude toward the side panel 12, so that the bottom cover 13 can be interference fit with the side panel 12, and when the upper cover 11 and the bottom cover 13 are tightly fitted with the heat exchange core 2 inside the shell 1, a certain gap is still maintained between the bottom cover 13 and the side panel 12, thereby ensuring the reliability of the installation of the heat exchange core 2.

[0050] Furthermore, an elastic member 3 is provided between at least one of the two end heat exchangers 23 and the inner wall of the side panel 12, that is, an elastic member 3 is provided between only one end heat exchanger 23 and the inner wall of the side panel 12, or an elastic member 3 is provided between both end heat exchangers 23 and the inner wall of the side panel 12. The elastic member 3 can be set as an elastic sheet, etc., and when the heat exchanger 100 is installed, the elastic member 3 is in a compressed and pre-tightened state between the end heat exchanger 23 and the inner wall of the side panel 12. The two ends of the intermediate heat exchanger 21 are respectively connected to the end heat exchanger 23 by plugging, and the elastic member 3 is provided between the end heat exchanger 23 and the inner wall of the side panel 12 to apply an elastic force to the end heat exchanger 23 toward the intermediate heat exchanger 21, so that the end heat exchanger 23 can be plugged and pre-tightened toward the intermediate heat exchanger 21 to ensure the reliability of the plug-in between the end heat exchanger 23 and the intermediate heat exchanger 21.

[0051] In addition, an elastic member 3 is arranged between the end heat exchange member 23 and the inner wall of the side panel 12 away from the connection between the inlet area 25 and the outlet area 26. When a gap is generated between the end heat exchange member 23 and the inner wall of the side panel 12 due to welding or the like, the elastic member 3 can still be pressed against the end heat exchange member 23 and the inner wall of the side panel 12 respectively under the action of elastic force to close the gap between the end heat exchange member 23 and the inner wall of the side panel 12, thereby preventing cooling water that is not undergoing heat exchange from flowing through the gap, thereby improving the heat exchange effect of the heat exchange core 2, and further improving the heat exchange efficiency of the heat exchanger 100.

[0052] In some embodiments, the elastic member 3 is constructed as an elastic sheet, and at least a portion of the elastic member 3 is constructed in a wave shape, one of the crests and troughs of the elastic member 3 presses against the inner wall of the side panel 12 and the other presses against the end heat exchange member 23 .

In this embodiment, as Figure 1-Figure 2 as well as Figure 4 As shown, the elastic member 3 is constructed in a wave shape as a whole. The elastic member 3 is constructed in a wave shape so that when a force is applied to the crests and troughs of the elastic member 3, the crests and troughs of the elastic member 3 can generate elastic forces in opposite directions for restoring deformation.

[0054] When the elastic member 3 is arranged between the end heat exchange member 23 and the inner wall of the side panel 12, one of the wave crests and wave troughs of the elastic member 3 presses against the inner wall of the side panel 12 and the other presses against the end heat exchange member 23, so that one of the wave crests and wave troughs of the elastic member 3 can apply an elastic force to the inner wall of the side panel 12, and the other of the wave crests and wave troughs can apply an elastic force to the end heat exchange member 23, so that the elastic member 3 is fixed between the end heat exchange member 23 and the inner wall of the side panel 12 to close the gap between the end heat exchange member 23 and the inner wall of the side panel 12, thereby ensuring the reliability of the plug-in connection between the end heat exchange member 23 and the intermediate heat exchange member 21 and avoiding the bypass of cooling water, thereby improving the heat exchange effect of the heat exchange core 2.

The number of peaks L1 and the number of troughs L2 of the elastic member 3 are set to satisfy: L1≥3, L2≥3, so that the elastic member 3 can be pressed between the end heat exchange member 23 and the intermediate heat exchange member 21 at multiple locations, thereby ensuring the reliability of the elastic member 3.
