DETAILED DESCRIPTION

[0056] Embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0057] The heat exchange assembly 1 according to an embodiment of the present application is described below with reference to Figures 1 to 7. The heat exchange assembly 1 is mainly used to exchange heat between batteries in a battery pack, thereby reducing the temperature of the battery pack and allowing the battery pack to operate normally.

[0058] As shown in Figures 1-7, a heat exchange assembly 1 according to an embodiment of the present application includes a heat exchange component 10. The heat exchange component 10 includes at least two heat exchange channel groups 111, which are independently disposed. The heat exchange component 10 also includes at least two converging flow channel groups 21, which are independently disposed. Each heat exchange channel group 11 is in communication with a corresponding converging flow channel group 21.

[0059] Specifically, as shown in Figures 3 and 7, the heat exchange assembly 10 includes a heat exchanger 11 and a conduit 20. The heat exchanger 11 mainly plays the role of heat exchange. The heat exchanger 11 can exchange heat for the battery pack, so that the battery pack can work normally. There are multiple heat exchangers 11, and each heat exchanger 11 is provided with a heat exchange channel group 111. The two heat exchange channel groups 111 in any two heat exchangers 11 are independently arranged. The conduit 20 mainly plays the role of diversion and confluence. At least two confluence flow groups 21 are provided on the conduit 20, and the two confluence flow groups 21 are independently arranged. The heat exchange medium can circulate in the heat exchange channel group 111 and the confluence flow group 21. The heat exchange medium can be a liquid heat exchange medium or a gas heat exchange medium.

[0060] It should be noted that different parts of the battery may generate different amounts of heat, and at least two heat exchange channel groups 111 correspond to different heat-generating parts of the battery. Providing at least two heat exchange channel groups 111 allows the heat exchange element 11 to provide more comprehensive heat exchange for the battery.

[0061] In general, at least two heat exchange channel groups 111 are provided, and the heat exchange temperatures between the two heat exchange channel groups 111 are different. In other words, the flow rate of the heat exchange medium flowing through each heat exchange channel group 111 is different. For example, the heat exchange channel group 111 where the heat exchange medium with a higher flow rate is located corresponds to the location where the battery generates more heat, while the heat exchange channel group 111 where the heat exchange medium with a lower flow rate is located corresponds to the location where the battery generates less heat. In this way, heat exchange can be better performed on the batteries according to the heat generation of the batteries in different heat exchange channel groups 111, thereby achieving temperature uniformity of the battery components.

[0062] In some embodiments of the present application, the multiple heat exchange elements 11 are integrally formed, such as stamped and brazed heat exchange plates, and the heat exchange elements 11 are part of the integral structure. The multiple heat exchange channels are divided into multiple independent heat exchange channel groups, thereby achieving independent heat dissipation or temperature reduction. Furthermore, in other embodiments of the present application, the multiple heat exchange elements 11 can be independent components, thereby achieving independent separation from each other.

[0063] As shown in Figure 1, the conduit 20 is arranged on the heat exchanger 11, and each heat exchange channel group 1,1 is connected to a corresponding conduit group 21. The conduit 20 is arranged on the heat exchanger 11, so that the conduit 20 can be fixed, making the arrangement of the conduit 20 more secure and stable, so that the conduit 20 can work better. It should be noted that the heat exchange medium flows into the heat exchanger 11 through the conduit 20, and after exchanging heat with the battery, it will flow back into the conduit 20. Therefore, the conduit 20 is arranged on the heat exchanger 11, which facilitates the coordination between the conduit 20 and the heat exchanger 11, thereby facilitating the circulation of the heat exchange medium.

[0064] The converging channel group 21 primarily guides the flow of the heat exchange medium. Positioning the converging channel group 21 on the converging member 20 allows the heat exchange medium to circulate within the converging member 20, thereby facilitating the diversion or convergence of the heat exchange medium within the converging member 20. Providing at least two converging channel groups 21, each independently positioned, is more rational, increasing the number of channels for diversion and convergence, and preventing interference between adjacent converging channel groups 21.

[0065] Each heat exchange channel group 111 is connected to a corresponding confluence channel group 21. It should be noted that the flow rates of the heat exchange medium entering different confluence channel groups 21 are different. Connecting each heat exchange channel group 111 to a corresponding confluence channel group 21 allows heat exchange mediums of different flow rates to flow into the desired heat exchange channel group 111. This allows the heat exchange temperatures between at least two heat exchange channel groups 111 to differ, thereby better cooling the battery.

[0066] Therefore, by connecting each heat exchange channel group 111 to a converging channel group 21, heat exchange media of different flow rates can correspond to the heat generation areas at different positions of the battery, that is, the flow rate of the heat exchange medium at different positions of the battery in the battery pack can be independently adjusted, which is beneficial to the cooling and heat dissipation of the battery. Moreover, the heat exchange component 10 can divert and converge the heat exchange medium flowing through, avoiding the setting of multiple connecting pipes to pass the heat exchange medium into at least two heat exchange channel groups 111, reducing the number of parts, and improving the integration of the heat exchange assembly 1, thereby reducing the volume of the heat exchange assembly 1 and saving the installation space of the heat exchange assembly 1.

[0067] In addition, in some embodiments of the present application, the heat exchange component 10 can ensure independent control of each heat exchange channel group 111 by independently arranging the two heat exchange channel groups 111 to independently adjust the flow rate of the heat exchange medium in each heat exchange channel group 111, thereby ensuring heat exchange at different positions of the battery assembly to achieve temperature uniformity between different positions of the battery assembly.

[0068] It should be noted that in some embodiments of the present application, as shown in FIG10 , the heat exchange assembly 10 includes a flow channel plate 12 and a first mounting plate 13 , with a heat exchange channel group 111 defined between the flow channel plate 12 and the first mounting plate 13 . The flow channel plate 12 may form flow channels for the heat exchange channel group 111 , while the first mounting plate 13 may seal the flow channels to prevent leakage of the heat exchange medium, thereby defining the overall structure of the heat exchange channel group 111 .

[0069] Similarly, as shown in Figure 10, the heat exchange assembly 10 further includes a manifold 120 and a second mounting plate 14. A converging flow channel group 21 is defined between the manifold 120 and the second mounting plate 14. The converging flow channel group 21 is connected to the heat exchange channel group 111. The converging flow channel of the converging flow channel group 21 is formed on the manifold 120, and the second mounting plate 14 can seal the flow channel to prevent leakage of the heat exchange medium, thereby defining the overall structure of the converging flow channel group 21.

[0070] Furthermore, as shown in FIG10 , in some embodiments of the present application, the first mounting plate 13 and the second mounting plate 14 are arranged opposite each other, the flow channel plate 12 is arranged on the side of the first mounting plate 13 away from the second mounting plate 14, and the manifold 120 is arranged on the side of the second mounting plate 14 away from the first mounting plate 13. In other words, the flow channel plate 12 and the manifold 120 are arranged away from each other, which is more reasonable and can save installation space. Moreover, when the heat exchange channel group 111 is designed on the flow channel plate 12, it does not interfere with the arrangement of the manifold 120. In addition, in the above-mentioned embodiment, the arrangement of the flow channel plate 12, the first mounting plate 13, the second mounting plate 14, and the manifold 120 can improve the utilization of the heat exchange assembly 10 in the thickness direction, thereby adapting to different battery packs and saving space in the length or width direction.

[0071] Furthermore, as shown in Figure 10, in some embodiments of the present application, the first mounting plate 13 and the second mounting plate 14 are arranged in a close fit, and the first mounting plate 13 is provided with a first through hole 131 connected to the heat exchange channel group 111, and the second mounting plate 14 is provided with a second through hole 141 connected to the confluence flow channel group 21. The first through hole 131 is connected to the second through hole 141 so that the heat exchange channel group 111 is connected to the corresponding confluence flow channel group 21. The heat exchange channel group 111 is arranged on the flow channel plate 12. The first mounting plate 13 is provided with a first through hole 131 connecting to the heat exchange channel group 111. The second mounting plate 14 is provided with a second through hole 141 connecting to the converging flow channel group 21. Since the first mounting plate 13 and the second mounting plate 14 are arranged between the flow channel plate 12 and the converging plate 120, the first through hole 131 and the second through hole 141 can connect the corresponding converging flow channel group 21 and the heat exchange channel group 111. Therefore, the external heat exchange medium can enter the heat exchange channel group 111 through the converging flow channel group 21, the second through hole 141 and the first through hole 131 in sequence, thereby achieving heat exchange for the battery. After heat exchange, the heat exchange medium can also flow back to the converging flow channel group 21 through the corresponding first through hole 131 and the second through hole 141, thereby forming a heat exchange circuit for the heat exchange medium.

[0072] Optionally, in some embodiments of the present application, as shown in FIG10 , the first mounting plate 13 and the second mounting plate 14 are integrally formed. Providing the first mounting plate 13 and the second mounting plate 14 as an integral structure can improve the integration of the heat exchange assembly 1 , facilitate the installation of the first mounting plate 13 and the second mounting plate 14 , improve the assembly efficiency of the heat exchange assembly 1 , and reduce the manufacturing cost of the heat exchange component.

[0073] In some embodiments of the present application, as shown in FIG1 , the manifold 120 includes a main plate 22 and multiple partitions 23. The main plate 22 and the second mounting plate 14 together form a cavity. The multiple partitions 23 are spaced apart within the cavity to divide the cavity into at least two converging flow channel groups 21. The main plate 22 is the main body of the manifold 120, primarily serving as a mounting and support mechanism, while the partitions 23 primarily serve as a barrier. The cavity primarily guides the flow of heat exchange medium. The main plate 22 and the second mounting plate 14 together form the cavity, and the multiple partitions 23 are spaced apart within the cavity. It is understood that the multiple partitions 23 can divide the cavity into at least two smaller cavities, each of which serves as a converging flow channel group 21. This allows different flow rates of heat exchange medium to flow into the at least two converging flow channel groups 21, thereby enabling different heat exchange temperatures between the at least two converging flow channel groups 21 and improving battery cooling.

[0074] In some embodiments of the present application, as shown in FIG3 , the heat exchange channel group 111 is provided with a first inlet 1211 and a first outlet 1212, and the confluence channel group 21 includes an inlet channel 211 and an outlet channel 212. The first inlet 1211 of the heat exchange channel group 111 is connected to the inlet channel 211 of the corresponding confluence channel group 21, and the first outlet 1212 of the heat exchange channel group 111 is connected to the outlet channel 212 of the corresponding confluence channel group 21. The first inlet 1211 primarily serves to guide the inflow of the heat exchange medium, and the first outlet 1212 primarily serves to guide the outflow of the heat exchange medium. Similarly, the inlet channel 211 primarily serves to guide the inflow of the heat exchange medium, and the outlet channel 212 primarily serves to guide the outflow of the heat exchange medium.

[0075] The first inlet 1211 of the heat exchange channel group 111 is connected to the inlet channel 211 of the corresponding confluence channel group 21, and the first outlet 1212 of the heat exchange channel group 111 is connected to the exhaust channel 212 of the corresponding confluence channel group 21. In this way, the heat exchange medium in the inlet channel 211 of the confluence channel group 21 will be diverted to the first inlet 1211 of the corresponding heat exchange channel group 111, and the heat exchange medium after heat exchange will flow from the first outlet 1212 of the heat exchange channel group 111 into the exhaust channel 212 of the corresponding confluence channel group 21, thereby ensuring the accuracy of the flow path of heat exchange media with different flow rates.

[0076] In some embodiments of the present application, the first inlet 1211 of the heat exchange channel group 111 and the first outlet 1212 of the heat exchange channel group 111 are located on the same side. By arranging the first inlet 1211 and the first outlet 1212 of the heat exchange channel group 111 on the same side, the manifold 120 can be arranged on one side of the first inlet 1211 and the first outlet 1212 of the heat exchange channel group 111. This facilitates communication between the manifold 120 and the first inlet 1211 and the first outlet 1212 of the heat exchange channel group 111, facilitates the design and layout of the convergent channel group 21, and improves the integration rate of the heat exchange assembly.

[0077] In some embodiments of the present application, as shown in FIG3 , the heat exchange channel group 111 is provided with a plurality of heat exchange channels 121, and the plurality of heat exchange channels 121 are spaced apart along the first direction. The heat exchange channel group 111 is provided with a plurality of heat exchange channels 121, and the plurality of heat exchange channels 121 are spaced apart along the first direction. This arrangement is more reasonable, can avoid interference between two adjacent heat exchange channels 121, and can make the arrangement of the heat exchange channels 121 more comprehensive, thereby improving the heat exchange effect of each heat exchange channel group 111.

[0078] Moreover, compared with setting only one heat exchange channel 121, setting multiple heat exchange channels 121 can shorten the flow distance of the heat exchange medium in the heat exchange channel 121 while ensuring that the total heat exchange distance and heat exchange area are similar. The pressure drop of the heat exchange medium is smaller and more energy-efficient, and the problem of reduced cooling effect due to temperature rise of the heat exchange medium after long-distance heat exchange can be avoided.

[0079] In addition, in some embodiments of the present application, as shown in FIG3 , in two adjacent heat exchange channels 121, the first inlet 1211 of one heat exchange channel 121 is disposed adjacent to the first outlet 1212 of the other heat exchange channel 121. It is understandable that, since the heat exchange medium exchanges heat with the battery in the heat exchange channel 121, the temperature of the heat exchange medium at the first inlet 1211 is lower than the temperature of the heat exchange medium at the first outlet 1212. Therefore, disposing the first inlet 1211 of one heat exchange channel 121 adjacent to the first outlet 1212 of the other heat exchange channel 121 can enhance heat exchange between the higher-temperature heat exchange medium and the lower-temperature heat exchange medium, thereby improving the temperature uniformity of the battery pack.

[0080] It should be noted that the first inlet 1211 and the first outlet 1212 of the same heat exchange channel 121 are located on the same side, and are staggered along the first direction. The first inlet 1211 and the first outlet 1212 of the same heat exchange channel 121 are arranged on the same side, so that after the manifold 120 is installed, it can be simultaneously connected to the first inlet 1211 and the first outlet 1212 of the same heat exchange channel 121, thereby facilitating the overall installation of the manifold 120. The first inlet 1211 and the first outlet 1212 of the same heat exchange channel 121 are staggered along the first direction, so that the first inlet 1211 of the same heat exchange channel 121 can correspond to the inlet channel 211 on the manifold 120, and the first outlet 1212 can correspond to the outlet channel 212 on the manifold 120. In addition, the first inlet 1211 and the first outlet 1212 of the same heat exchange channel 121 are staggered along the first direction, and the manifold 120 can be arranged regularly, reducing the difficulty of manufacturing the manifold 120 and improving the integration efficiency of the manifold channel group.

[0081] Furthermore, in some embodiments, the heat exchange channel 121 extends along the second direction, and in the second direction, the distance between the first inlet 1211 and the first outlet 1212 of the same heat exchange channel 121 is within a range of 5 mm to 8 mm. That is, within the same heat exchange channel 121, there is a certain spacing between the first inlet 1211 and the first outlet 1212 in the second direction, and the range of this spacing is relatively reasonable. This facilitates distinguishing the positions of the first inlet 1211 and the first outlet 1212 and also facilitates the corresponding arrangement of the inlet channel 211 and the outlet channel 212 on the manifold 120. Furthermore, the above arrangement can also avoid the problem of the overall volume of the manifold 120 being excessively large after the inlet channel 211 and the outlet channel 212 on the manifold 120 are connected to the first inlet 1211 and the first outlet 1212, thereby making the manifold 120 inconvenient to arrange and increasing costs. Furthermore, the above arrangement can ensure that the heat exchange channel group has sufficient heat exchange area, thereby improving the heat exchange efficiency of the entire battery pack.

[0082] Furthermore, the first inlets 1211 of the plurality of heat exchange channels 121 are spaced apart along a first straight line, and the first outlets 1212 of the plurality of heat exchange channels 121 are spaced apart along a second straight line. In other words, the first inlets 1211 of the plurality of heat exchange channels 121 are all arranged along the first straight line, and the first outlets 1212 of the plurality of heat exchange channels 121 are all arranged along the second straight line. Thus, when the inlet channels 211 and the outlet channels 212 are provided on the manifold 120, the inlet channels 211 can also be arranged along the first straight line, and the outlet channels 212 can be arranged along the second straight line, thereby facilitating the processing and arrangement of the inlet channels 211 and the outlet channels 212 on the manifold 120.

[0083] The first straight line is arranged in parallel with the second straight line. That is, the first inlets 1211 of the plurality of heat exchange channels 121 are arranged in the first straight line, and the first outlets 1212 of the plurality of heat exchange channels 121 are arranged in the second straight line. The first straight line is arranged in parallel with the second straight line, so that the arrangement of the first inlets 1211 and the first outlets 1212 of the plurality of heat exchange channels 121 is more orderly.

[0084] Alternatively, the first straight line and the second straight line both coincide with the first direction. When the first straight line and the second straight line both coincide with the first direction, the first straight line is vertically arranged along the first direction, and the second straight line is also vertically arranged along the first direction. This can make the arrangement of the first inlets 1211 and the first outlets 1212 of the multiple heat exchange channels 121 more orderly, and also facilitate the processing and arrangement of the inlet channels 211 and the outlet channels 212 on the manifold 120, thereby reducing the overall volume of the manifold 120.

[0085] In addition, in the embodiment of the present application, as shown in Figures 4 to 6, the heat exchange assembly 1 also includes a valve body assembly 30, and the valve body assembly 30 is provided with a plurality of second inlets 31 and a plurality of second outlets 32. The confluence channel group 21 includes an inlet channel 211 and an outlet channel 212. One second inlet 31 is connected to the outlet channel 212 of a confluence channel group 21, and one second outlet 32 ​​is connected to the inlet channel 211 of a confluence channel group 21. Among them, the valve body assembly 30 is mainly used to control the flow rate of the heat exchange medium. The second inlet 31 mainly plays the role of guiding the heat exchange medium to flow into the valve body assembly 30, and the second outlet 32 ​​mainly plays the role of guiding the heat exchange medium to flow out of the valve body assembly 30. Similarly, the inlet channel 211 mainly plays the role of guiding the inflow of the heat exchange medium, and the outlet channel 212 mainly plays the role of guiding the outflow of the heat exchange medium.

[0086] It should be noted that the valve body assembly 30 can be a single integral structure, on which multiple second inlets 31 and multiple second outlets 32 are provided. The valve body assembly 30 can also be a split structure, for example, the valve body assembly 30 includes a first valve body and a second valve body, the first valve body is provided with multiple second inlets 31, and the second valve body is provided with multiple second outlets 32.

[0087] Furthermore, in the above embodiment, the valve body assembly 30 may be provided with a plurality of second outlets 32, and the second inlet 31 may be provided with one or more, wherein the second inlet 31 only needs to be in communication with one exhaust channel 212. Specifically, for the heat exchange assembly, it is only necessary to control the flow rate at the inlet to control the flow rate within the heat exchange channel group 111. Therefore, this application does not limit the number of second inlets 31 of the valve body assembly 30.

[0088] Specifically, a second inlet 31 is connected to the exhaust channel 212 of a confluence flow channel group 21, that is, the exhaust channel 212 of each confluence flow channel group 21 has a corresponding second inlet 31 connected thereto, so that the heat exchange medium in each exhaust channel 212 can flow into the interior of the valve body assembly 30 through the corresponding second inlet 31 after heat exchange, thereby discharging the heat exchange medium from the confluence flow channel group 21. Similarly, the second outlet 32 ​​is connected to the inlet channel 211 of the confluence flow channel group 21 in a one-to-one correspondence, that is, the inlet channel 211 of each confluence flow channel group 21 has a corresponding second outlet 32 ​​connected thereto. In this way, the external heat exchange medium of different flow rates flows into the corresponding inlet channel 211 through the corresponding second outlet 32 ​​after flowing into the valve body assembly 30, and can then enter the corresponding heat exchange channel group 111, thereby better exchanging heat and cooling the battery.

[0089] Furthermore, in some embodiments of the present application, the heat exchange assembly 1 further includes a second connecting pipe and a first connecting pipe, wherein the second connecting pipe is connected between the second inlet 31 and the discharge channel 212 of the converging flow channel group 21, and the first connecting pipe is connected between the second outlet 32 ​​and the inlet channel 211 of the converging flow channel group 21. Both the second connecting pipe and the first connecting pipe can function as a communication channel. By connecting the second connecting pipe between the second inlet 31 and the discharge channel 212 of the converging flow channel group 21, the second inlet 31 and the discharge channel 212 can be connected by the second connecting pipe, thereby allowing the heat exchange medium in the converging flow channel group 21 to flow from the discharge channel 212 into the interior of the valve body assembly 30.

[0090] Similarly, the first connecting pipe is connected between the second outlet 32 ​​and the inlet channel 211 of the converging flow channel assembly 21. In this way, the second outlet 32 ​​and the inlet channel 211 can be connected by the first connecting pipe, so that the external heat exchange medium can flow from the valve body assembly 30 into the converging flow channel assembly 21. The second connecting pipe and the first connecting pipe can be set and selected according to actual working conditions. For example, the second connecting pipe and the first connecting pipe can both be nylon tubes, and of course other suitable materials can also be used.

[0091] In addition, in the above embodiment, for the heat exchange component, it is only necessary to control the flow at the inlet to control the flow in the heat exchange channel group 111, so the present application does not limit the number of second connecting pipes.

[0092] In addition, as shown in Figures 5 and 6, the heat exchange assembly 1 also includes an adjusting member 40, which is movably disposed at the second outlet 32 ​​to adjust the flow area at the second outlet 32, or the adjusting member 40 is movably disposed in the first connecting pipe to adjust the flow area in the first connecting pipe.

[0093] The regulating member 40 primarily serves to regulate the flow rate of the heat exchange medium flowing through the valve body assembly 30. It should be noted that the valve body assembly 30 is further provided with a third inlet 33 and a third outlet 34. The third inlet 33 is connected to the second outlet 32, and the second inlet 31 is connected to the third outlet 34. The heat exchange medium can enter the valve body assembly 30 through the third inlet 33 and flow into the second outlet 32, or it can enter the valve body assembly 30 through the second inlet 31 and flow into the third outlet 34, thereby being discharged from the valve body assembly 30.

[0094] The regulating member 40 is movably disposed at the second outlet 32. When the regulating member 40 does not block the second outlet 32, the flow area at the second outlet 32 ​​does not change, and the heat exchange medium entering the valve body assembly 30 from the outside through the third inlet 33 can flow normally from the second outlet 32 ​​into the converging flow channel group 21. When the regulating member 40 begins to move toward the second outlet 32, it can block the second outlet 32. The blocking of the regulating member 40 gradually reduces the flow area at the second outlet 32, thereby controlling the flow rate of the heat exchange medium at the second outlet 32. When the cross-sectional dimensions of the regulating member 40 are set to be the same as the cross-sectional dimensions of the second outlet 32, and the regulating member 40 completely blocks the second outlet 32, the heat exchange medium cannot pass through the second outlet 32, thereby preventing the heat exchange medium from entering the converging flow channel group 21. Of course, the adjusting member 40 can also be movably disposed within the first connecting tube. By varying the length or cross-sectional area of ​​the adjusting member 40 extending into the first connecting tube, the cross-sectional area of ​​the heat exchange medium flowing through the first connecting tube can be adjusted, thereby controlling the flow rate of the heat exchange medium. In this way, the flow rate of the heat exchange medium entering the different converging flow channel groups 21 can be controlled, thereby achieving better heat exchange and cooling of the battery.

[0095] In addition, as shown in Figures 4 and 6, the heat exchange assembly 1 also includes a control component 50, which includes a driving member and a transmission member. The driving member and the transmission member are driven in conjunction with each other, and the transmission member and the adjustment member 40 are driven in conjunction with each other. Among them, the control component 50 mainly plays a controlling role and can control the movement of the adjustment member 40. The driving member mainly plays a driving role, and the transmission member mainly plays a transmission role. The driving member and the transmission member are driven in conjunction with each other, so that the driving member can provide power to the transmission member, so that the transmission member can perform corresponding actions. The transmission member and the adjustment member 40 are driven in conjunction with each other, so that the transmission member can be used to drive the adjustment member 40 to move. The movement of the adjustment member 40 can then control the flow area at the second outlet 32 ​​or in the first connecting pipe, thereby achieving control of the flow rate of the heat exchange medium. In addition, the movement of the adjustment member 40 can also be controlled by spring control. Of course, other suitable control methods can also be used.

[0096] Furthermore, as shown in Figure 9, the heat exchange assembly 1 also includes a heater 60. The heater 60 is disposed within the passage of the valve body assembly 30 connected to the second outlet 32, and / or within the first connecting pipe. The heater 60 primarily serves a heating function. Placing the heater 60 within the passage of the valve body assembly 30 connected to the second outlet 32 ​​heats the heat exchange medium flowing into the valve body assembly 30. This heated heat exchange medium then enters the confluence flow channel assembly 21 through the second outlet 32, where it can then heat the battery. This configuration is suitable for use in cold weather. Alternatively, the heater 60 can be disposed within the first connecting pipe to heat the heat exchange medium flowing through it. Alternatively, the heater 60 can be disposed within both the passage of the valve body assembly 30 connected to the second outlet 32 ​​and the first connecting pipe to further heat the heat exchange medium. The heater 60 can be a heating wire.

[0097] Specifically, for example: under low-temperature heating conditions or active insulation conditions, the heat exchange medium in the edge battery area is additionally heated for a second time, thereby realizing the regulation function of different areas and different temperatures. In this way, in the entire power consumption system, fine-grained regulation of thermal management of different temperatures and different flow rates of the heat exchange medium can be achieved, so that the battery always operates at an appropriate temperature and reduces the temperature difference between each battery in the battery pack system.

[0098] As an optional embodiment, the heat exchange assembly 10 includes a first heat exchange member 110 and a second heat exchange member, and the valve body assembly 30 has a first side and a second side arranged opposite to each other, and the first side and the second side are both provided with multiple second inlets 31 and multiple second outlets 32, and the multiple second inlets 31 and the multiple second outlets 32 located on the first side are respectively connected to the manifold 20 arranged on the first heat exchange member 110, and the multiple second inlets 31 and the multiple second outlets 32 located on the second side are respectively connected to the manifold 20 arranged on the second heat exchange member.

[0099] The first heat exchange element 110 and the second heat exchange element can both perform heat exchange, thus achieving a double-layer heat exchange effect. This double-layer heat exchange arrangement can better heat the battery. Multiple second inlets 31 and multiple second outlets 32 are provided on opposite sides of the valve body assembly 30. Heat exchange medium flowing from the outside into the valve body assembly 30 can flow into the manifold 20 through the multiple second outlets 32. Similarly, heat exchange medium within the manifold 20 can also flow into the valve body assembly 30 through the multiple second inlets 31.

[0100] The multiple second inlets 31 and the multiple second outlets 32 located on the first side are respectively connected to the manifold 20 provided on the first heat exchanger 110, and the multiple second inlets 31 and the multiple second outlets 32 located on the second side are respectively connected to the manifold 20 provided on the second heat exchanger. Specifically, the heat exchange medium entering the interior of the valve body assembly 30 can flow into the first heat exchanger 110 through the second outlets 32 on the first side, and then flow into the interior of the valve body assembly 30 through the second inlet 31 on the first side after heat exchange, and then be discharged. Similarly, the heat exchange medium entering the interior of the valve body assembly 30 can flow into the second heat exchanger through the second outlet 32 ​​on the second side, and then flow into the interior of the valve body assembly 30 through the second inlet 31 on the second side after heat exchange, and then be discharged. This can save layout space while providing heat exchange medium to the first heat exchanger 110 and the second heat exchanger. It should be noted that the flow rate and opening and closing time of the heat exchange medium entering the first heat exchange element 110 and the second heat exchange element from the valve body assembly 30 can be individually controlled by the above-mentioned adjustment element 40.

[0101] Alternatively, a plurality of second outlets 32 are provided on one side of the valve body assembly 30. The second outlets 32 include a first heat exchange outlet 321 and a second heat exchange outlet. The plurality of first heat exchange outlets 321 are respectively connected to the manifold 20 provided on the first heat exchange element 110, and the plurality of second heat exchange outlets are respectively connected to the manifold 20 provided on the second heat exchange element. In other words, all the second outlets 32 can be provided on one side of the valve body assembly 30, and then the second outlets 32 can be divided into the first heat exchange outlet 321 and the second heat exchange outlet. The plurality of first heat exchange outlets 321 are respectively connected to the manifold 20 provided on the first heat exchange element 110, and the plurality of second heat exchange outlets are respectively connected to the manifold 20 provided on the second heat exchange element. In this way, the heat exchange medium can also be respectively introduced into the first heat exchange element 110 and the second heat exchange element through the valve body assembly 30, thereby achieving joint heat exchange between the first heat exchange element 110 and the second heat exchange element.

[0102] Among them, the above-mentioned first heat exchange element 110 and the second heat exchange element both include multiple heat exchange channel groups 111 and multiple converging channel groups 21. Therefore, the provision of the first heat exchange element 110 and the second heat exchange element can ensure heat exchange for objects such as batteries in different directions and positions, thereby improving cooling efficiency.

[0103] As an optional embodiment, the valve assembly 30 is a solenoid valve. This allows for easier control of the flow of heat exchange medium within the valve assembly 30. Furthermore, solenoid valves are typically smaller, saving installation space and offering faster response times.

[0104] As shown in Figure 7, it should be noted that the heat exchange assembly 10 can also be divided into multiple module areas. For example, the upper portion of Figure 7 represents the first module area 2, and the lower portion represents the second module area 3. In this way, the flow rate and opening and closing times of the heat exchange medium in the first module area 2 and the first module area 3 can be independently controlled through the coordination between the manifold 20 and the multiple heat exchange channel groups 111. This allows for independent control of the flow rate at different battery locations within the first module area 2 and the first module area 3. In other words, the flow rate at different battery locations within the first module area 2 and the first module area 3 can be regulated.

[0105] In addition, a plurality of heat exchange channel groups 111 are provided in the first module area 2 or the second module area 3 , and each heat exchange channel can correspond to an independent control flow, thereby achieving temperature regulation at different positions of the battery assembly.

[0106] According to an embodiment of the present application, a battery pack 100 , as shown in FIG13 , includes the heat exchange assembly 1 according to any one of the above embodiments.

[0107] The heat exchange assembly 1 is used to exchange heat for battery components, thereby improving the performance of the battery components. Specifically, during charging and discharging or under other operating conditions, the battery components may have some areas with inconsistent temperatures from other areas, resulting in different temperature zones in the battery, which in turn limits the performance of the battery components. By using the heat exchange assembly 1 disclosed in the embodiment of the present application, the flow rate of the heat exchange medium in different heat exchange channel groups 111 can be independently adjusted, thereby achieving temperature control of battery components in different temperature zones, thereby reducing the temperature difference between different positions of the battery components and improving the temperature uniformity of the battery components.

[0108] As shown in FIG8 , the battery pack 100 further includes a battery assembly 70, which includes at least a first temperature zone and a second temperature zone. A heat exchange channel group 111 of the heat exchange assembly 10 is provided corresponding to the first temperature zone, and another heat exchange channel group 111 is provided corresponding to the second temperature zone, so as to independently adjust the battery temperatures in the first and second temperature zones. That is, at least a first temperature zone and a second temperature zone with different temperatures are formed on the battery assembly 70. One heat exchange channel group 111 is provided corresponding to the first temperature zone, and the heat exchange channel group 111 can perform heat exchange and cooling on the battery assembly 70 in the first temperature zone. Another heat exchange channel group 111 is provided corresponding to the second temperature zone, and the heat exchange channel group 111 can perform heat exchange and cooling on the battery assembly 70 in the second temperature zone. In this way, the battery temperatures in the first and second temperature zones can be independently adjusted, thereby improving the heat exchange and cooling effect of the battery assembly 70.

[0109] In addition, the battery pack 100 also includes multiple heat exchange parts 11, and the battery assembly 70 includes multiple single cells, which extend along a first direction and are arranged along a second direction, wherein the single cells are provided with poles, and the area of ​​the battery assembly 70 adjacent to the pole of each single cell is a first temperature zone, and the remaining areas of the battery assembly 70 except the first temperature zone are a second temperature zone. A heat exchange channel group 111 of the heat exchange assembly 10 is opposite to and heat-exchanges with part of the battery assembly 70 corresponding to the first temperature zone in a third direction, and another heat exchange channel group 111 of the heat exchange assembly is opposite to and heat-exchanges with part of the battery assembly 70 corresponding to the second temperature zone in the third direction, and the third direction is perpendicular to the first direction and the second direction.

[0110] It should be noted that one heat exchange channel group 111 of the heat exchange assembly is a first heat exchange channel group, and the other heat exchange channel group 111 of the heat exchange assembly is a second heat exchange channel group. Specifically, the temperature of the single battery cell is higher at the position adjacent to the pole, that is, the first temperature zone, while the temperature at other positions is relatively low, that is, the second temperature zone. Both the first heat exchange channel group and the second heat exchange channel group can play a role in heat exchange. The first heat exchange channel group is directly opposite and exchanges heat with the part of the battery assembly 70 corresponding to the first temperature zone, and the second heat exchange channel group is directly opposite and exchanges heat with the part of the battery assembly 70 corresponding to the second temperature zone. In this way, the flow rates in the first heat exchange channel group and the second heat exchange channel group can be independently adjusted to ensure the temperature uniformity of the battery components and improve the overall heat exchange effect of the battery assembly 70.

[0111] Of course, each single cell has at least two poles, which are located at the two ends of the corresponding single cell along the first direction. The first temperature zone has a first sub-temperature zone and a second sub-temperature zone. The portion of the battery assembly 70 corresponding to the pole on one side is the first sub-temperature zone, and the portion of the battery assembly 70 corresponding to the pole on the other side is the second sub-temperature zone. The second temperature zone is located between the first and second sub-temperature zones. A heat exchange channel group 111 in the heat exchange assembly has a first heat exchange sub-channel group and a second heat exchange sub-channel group. The first heat exchange sub-channel group performs heat exchange with the portion of the battery assembly 70 corresponding to the first sub-temperature zone, and the second heat exchange sub-channel group performs heat exchange with the portion of the battery assembly 70 corresponding to the second sub-temperature zone.

[0112] That is to say, poles are provided at both ends of the single cell along the first direction, and correspondingly, a first sub-temperature zone and a second sub-temperature zone are respectively formed at both ends of the single cell along the first direction, and the second temperature zone is between the first sub-temperature zone and the second sub-temperature zone, and the first heat exchange component 110 is divided into a first heat exchange sub-channel group and a second heat exchange sub-channel group. The first heat exchange sub-channel group exchanges heat for part of the battery assembly 70 corresponding to the first sub-temperature zone, and the second heat exchange sub-channel group exchanges heat for part of the battery assembly 70 corresponding to the second sub-temperature zone. In this way, it can be ensured that effective heat exchange and cooling are performed on the positions of the two poles of the single cell, so that the battery assembly 70 can work normally and stably.

[0113] In addition, the first heat exchange element 110 forms a first heat exchange zone, which corresponds to the first temperature zone, and the second heat exchange element forms a second heat exchange zone, which corresponds to the second temperature zone. The first heat exchange zone includes a first region and a second region, which are arranged on opposite sides of the second heat exchange zone. Based on the above, it can be seen that the first heat exchange zone has a better heat exchange effect than the second heat exchange zone. The first heat exchange zone corresponds to the positions of the battery assembly 70 at both ends along the first direction, that is, the first region and the second region correspond to the positions of the battery assembly 70 at both ends along the first direction. Correspondingly, the second heat exchange zone is located in the middle of the first region and the second region. In this way, the battery assembly 70 can be better heat exchanged and cooled.

[0114] In addition, in the embodiment of the present application, the heat exchange component is arranged on one side of the battery assembly 70 to exchange heat for the entire battery assembly 70, thereby improving the temperature uniformity of the battery assembly 70.

[0115] According to an embodiment of the present application, the power consumption system 1000 includes the battery pack 100 of the above embodiment, as shown in Figure 14. The power consumption system 1000 includes a vehicle, an energy storage system, or an energy storage cabinet.
