[0085] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0086] The battery cannot work properly when the temperature is too high or too low, so the battery temperature needs to be controlled.

[0087] In some cases, the battery uses a heat exchange element to dissipate heat from the battery cells, thereby achieving the purpose of battery temperature control; the battery is usually equipped with multiple heat exchange elements and multiple rows of battery cells, and the multiple heat exchange elements and multiple rows of battery cells are arranged alternately, and a row of battery cells is arranged between two adjacent heat exchange elements. A row of battery cells includes multiple battery cells, but the heat exchange effects of each battery cell are different, resulting in temperature differences between the battery cells in the same row of battery cells.

[0088] The applicant found that one of the main reasons why the heat exchange effects of each battery cell in the same row of battery cells are different is that: in the heat exchange elements located on opposite sides of the same row of battery cells, the heat exchange medium flows into the heat exchange elements from the first end of the same side of the two heat exchange elements, and then flows out from the second end of the same other side of the two heat exchange elements; and in the process of the heat exchange medium flowing from the first end to the second end, the heat exchange medium exchanges heat with each battery cell in the row of battery cells in turn, and the heat exchange effect becomes worse and worse, resulting in the heat exchange effect of the battery cell close to the first end being better than the heat exchange effect of the battery cell close to the second end, which in turn leads to a large temperature difference between the battery cells in the same row of battery cells, thereby affecting the performance of the battery.

[0089] Specifically, when the temperature of the heat exchange medium flowing into the heat exchange element is lower than the temperature of the battery cell, the heat exchange medium absorbs the heat of each battery cell in turn during the process of flowing from the first end to the second end, and the temperature of the heat exchange medium becomes higher and higher. In this way, the temperature of the heat exchange medium that exchanges heat with the battery cell near the first end is low, the heat exchange effect is good, the cooling effect is good, and the temperature is low; while the temperature of the heat exchange medium that exchanges heat with the battery cell near the second end is high, the heat exchange effect is poor, the cooling effect is relatively poor, and the temperature is high. Similarly, when the temperature of the heat exchange medium that flows into the heat exchange element is higher than the temperature of the battery cell, the heat exchange medium exchanges heat with each battery cell in turn during the process of flowing from the first end to the second end, and the temperature of the heat exchange medium gradually decreases. In this way, the temperature of the heat exchange medium that exchanges heat with the battery cell near the first end is high, the heat exchange effect is good, the heating effect is good, and the temperature is high; while the temperature of the heat exchange medium that exchanges heat with the battery cell near the second end is low, the heat exchange effect is poor, the heating effect is relatively poor, and the temperature is low. This leads to a temperature difference between the battery cells in the same row of battery cells.

[0090] In order to reduce the temperature difference between the battery cells in the same row of battery cells, the applicant has designed a heat exchange component after in-depth research, in which the first inflow end of the first heat exchange element and the second outflow end of the second heat exchange element are located on the same side of the first heat exchange element, and the second inflow end of the second heat exchange element and the first outflow end of the first heat exchange element are located on the other side of the first heat exchange element, so that the flow direction of the heat exchange medium in the first heat exchange element is opposite to the flow direction of the heat exchange medium in the second heat exchange element, and the heat exchange effect on the two sides of this row of battery cells increases in opposite directions, so that the comprehensive heat exchange effect of a row of battery cells is uniformed, thereby improving the temperature difference between the battery cells in the same row of battery cells and improving the performance of the battery.

[0091] The heat exchange assembly, battery, and electrical device using the battery as a power source disclosed in the embodiments of the present application may be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery-powered vehicle, an electric car, a ship, a spacecraft, and the like. The electric toy may include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, and the spacecraft may include airplanes, rockets, space shuttles, and spacecraft, and the like.

[0092] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0093] Please refer to Figure 1, which is a schematic structural diagram of a vehicle 1000 provided in some embodiments of the present application. The vehicle 1000 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 1100 is provided inside the vehicle 1000, and the battery 1100 can be provided at the bottom, head or tail of the vehicle 1000. The battery 1100 can be used to power the vehicle 1000. For example, the battery 1100 can serve as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 1200 and a motor 1300. The controller 1200 is used to control the battery 1100 to power the motor 1300, for example, for starting, navigating and driving the vehicle 1000.

[0094] In some embodiments of the present application, the battery 1100 can serve not only as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0095] Referring to Figure 2 , as an embodiment of a battery 1100 , battery 1100 includes a housing 10 and battery cells, with the battery cells being housed within the housing 10 . The battery housing 10 is used to provide a storage space for the battery cells and can have various structures. In some embodiments, the battery housing 10 can include a first portion 11 and a second portion 12 , which overlap with each other and together define a storage space for the battery cells. The second portion 12 can be a hollow structure with one end open, and the first portion 11 can be a plate-like structure, overlapping the open side of the second portion 12 so that the first portion 11 and the second portion 12 together define a storage space. Alternatively, the first portion 11 and the second portion 12 can each be a hollow structure with one end open, with the open side of the first portion 11 overlapping the open side of the second portion 12. Of course, the battery housing 10 formed by the first portion 11 and the second portion 12 can have various shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0096] In battery 1100, there may be multiple battery cells, which may be connected in series, in parallel, or in a hybrid configuration. A hybrid configuration refers to multiple battery cells connected in both series and parallel. Specifically, a battery cell may be a battery cell 20 or a battery module. A battery module is a modular component formed by assembling multiple battery cells 20.

[0097] In one embodiment, multiple battery cells 20 may be directly connected in series, parallel, or hybrid, and the entire battery cell 20 may then be housed within the housing 10. Alternatively, the battery 1100 may be constructed by first connecting multiple battery cells 20 in series, parallel, or hybrid to form a battery module, which is then connected in series, parallel, or hybrid to form a complete battery module, and then housed within the housing 10. The battery 1100 may also include other structures, such as a busbar assembly for electrically connecting the multiple battery cells 20.

[0098] Each battery cell 20 may be a secondary battery or a primary battery, and may also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 may be cylindrical, flat, rectangular, or in other shapes.

[0099] As another embodiment of the battery 1100 , the battery 1100 may not include the housing 10 , but may be assembled into an electrical device by electrically connecting a plurality of battery cells 20 and forming a whole with necessary fixing structures.

[0100] Please refer to Figure 3, which is a schematic diagram of the exploded structure of a battery cell 20 provided in some embodiments of the present application. A battery cell 20 is the smallest unit that makes up a battery. As shown in Figure 3, a battery cell 20 includes an end cap 21, a housing 22, an electrode assembly 23, and other functional components.

[0101] The end cap 21 is a component that covers the opening of the outer shell 22 to isolate the internal environment of the battery cell 20 from the external environment. Without limitation, the shape of the end cap 21 can be adapted to the shape of the outer shell 22 to match the outer shell 22. Optionally, the end cap 21 can be made of a material with a certain hardness and strength (such as an aluminum alloy). This makes the end cap 21 less likely to deform when subjected to compression or collision, allowing the battery cell 20 to have higher structural strength and improved safety performance. Functional components such as electrode terminals can be provided on the end cap 21. The electrode terminals can be used to electrically connect to the electrode assembly 23 for outputting or inputting electrical energy into or out of the battery cell 20. In some embodiments, the end cap 21 can also be provided with a pressure relief mechanism for relieving internal pressure when the internal pressure or temperature of the battery cell 20 reaches a threshold. The end cap 21 can also be made of a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application are not particularly limited in this regard. In some embodiments, an insulating member may be provided inside the end cap 21 to isolate the electrical connection components in the housing 22 from the end cap 21 to reduce the risk of short circuit. For example, the insulating member may be made of plastic, rubber, or the like.

The outer shell 22 can be made of a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and this embodiment of the present application does not impose any particular limitations on this.

The electrode assembly 23 is mainly formed by winding or stacking positive and negative electrode sheets. The parts of the positive and negative electrode sheets with active materials constitute the main body of the electrode assembly 23, and the parts of the positive and negative electrode sheets without active materials each constitute a tab. The positive and negative electrode tabs may be located together at one end of the main body or respectively at both ends of the main body. During the charge and discharge process of the battery, the positive electrode active material and the negative electrode active material react with the electrolyte, and the tabs connect the electrode terminals to form a current loop.

The first heat exchange member 100 is configured with a first heat exchange space 1001, a first inlet end 111 and a first outlet end 131. The first heat exchange space 1001 is for the heat exchange medium to flow, and the first inlet end 111 and the first outlet end 131 are both connected to the first heat exchange space 1001; the second heat exchange member 200 is configured with a second heat exchange space 210, a second inlet end 220 and a second outlet end 230. The heat exchange medium flows through the space 210, and the second inlet end 220 and the second outlet end 230 are both connected to the second heat exchange space 210; the first heat exchange element 100 and the second heat exchange element 200 are arranged alternately, and an accommodating space 1002 is constructed between adjacent first heat exchange elements 100 and second heat exchange elements 200; the first inlet end 111 and the second outflow end 230 are located on the same side of the first heat exchange element 100, and the second inlet end 220 and the first outflow end 131 are located on the other side of the first heat exchange element 100; the first inlet end 111 and the second inflow end 220 are both connected to the inlet pipe assembly 300; the first outflow end 131 and the second outflow end 230 are both connected to the outflow pipe assembly 400.

[0106] The first heat exchange element 100 is a component made of a heat-conducting material. The heat-conducting material is a material that can transfer heat, so that the heat exchange medium in the first heat exchange space 1001 can exchange heat with the battery unit through the heat-conducting material.

[0107] At least one first heat exchange element 100. It can be understood that a heat exchange component 1 can include one or more first heat exchange elements 100. For example, as shown in Figures 4 and 5, the heat exchange component 1 includes five first heat exchange elements 100, and the five first heat exchange elements 100 are arranged at intervals along the thickness direction of the first heat exchange element 100, but is not limited to this. The number of first heat exchange elements 100 can be one, two, three or four, or six or even more.

[0108] The second heat exchange element 200 is a component made of a heat-conducting material. The heat-conducting material is a material that can transfer heat, so that the heat exchange medium in the second heat exchange space 210 can exchange heat with the battery unit through the heat-conducting material.

[0109] At least one second heat exchange element 200. It can be understood that a heat exchange component 1 can include one or more second heat exchange elements 200. For example, as shown in Figures 4 and 5, the heat exchange component 1 includes five second heat exchange elements 200, and the five second heat exchange elements 200 are arranged at intervals along the thickness direction of the second heat exchange element 200, but is not limited to this. The number of second heat exchange elements 200 can be one, two, three or four, or six or even more.

[0110] The thickness direction, for example, as shown in Figures 4 and 5, is the Y direction. The description of the length direction and height direction will also appear in the following content. For example, as shown in Figures 4 and 5, the height direction is the Z direction and the length direction is the X direction.

[0111] The first heat exchange elements 100 and the second heat exchange elements 200 are arranged alternately. It is understood that a second heat exchange element 200 is provided between two adjacent first heat exchange elements 100, and a first heat exchange element 100 is provided between two adjacent second heat exchange elements 200. A receiving space 1002 is constructed between adjacent first heat exchange elements 100 and second heat exchange elements 200. It is understood that the receiving space 1002 can accommodate a row of battery cells, and the opposite sides of the battery cells exchange heat with the first heat exchange element 100 and the second heat exchange element 200 respectively. For example, as shown in Figures 4 and 5, the first heat exchange elements 100 and the second heat exchange elements 200 are alternately arranged along the thickness direction, and the gaps between adjacent first heat exchange elements 100 and second heat exchange elements 200 constitute the receiving space 1002. The first heat exchange elements 100 and the second heat exchange elements 200 can be parallel or non-parallel. The specific arrangement can be designed according to the shape of the battery and is not limited here.

[0112] A row of battery cells may include one or more battery cells; when a row of battery cells includes one battery cell, the heat exchange effects at different locations of the battery cell are different, resulting in a temperature difference between different locations of the battery cell, and the heat exchange assembly 1 can improve the temperature difference between different locations on the battery cell; when a row of battery cells includes multiple battery cells, the multiple battery cells are arranged along the length direction of the first heat exchange element 100, but the heat exchange effects of the battery cells are different, resulting in a large temperature difference between the battery cells, and the heat exchange assembly 1 can improve the temperature difference between the battery cells. For ease of description, the embodiments of the present application are described as an example of a row of battery cells including multiple battery cells, wherein a row of battery cells may include two, three, or more than four battery cells.

[0113] The first heat exchange space 1001 refers to the cavity space constructed in the first heat exchange element 100 for the flow of heat exchange medium. When the heat exchange medium flows in the first heat exchange space 1001, heat is exchanged with the battery unit through the first heat exchange element 100, thereby realizing heat exchange of the battery unit.

[0114] The first inflow end 111 refers to one of the two opposite ends of the first heat exchange element 100. For example, as shown in Figure 4, one of the two opposite ends of the first heat exchange element 100 distributed along the length direction, that is, the first inflow end 111 is the right end of the first heat exchange element 100.

[0115] The first outflow end 131 refers to the other end of the two opposite ends of the first heat exchange element 100, for example, as shown in Figure 4, the other end of the two opposite ends of the first heat exchange element 100 distributed along the length direction; that is, the first inflow end 111 is the left end of the first heat exchange element 100.

[0116] The first inflow end 111 and the first outflow end 131 are both connected to the first heat exchange space 1001; it can be understood that the heat exchange medium flows into the first heat exchange space 1001 from the first inflow end 111, and then flows out of the first heat exchange element 100 from the first outflow end 131 after passing through the first heat exchange space 1001 and exchanging heat with the battery unit; that is, for example, as shown in Figure 4, the heat exchange medium flows into the first heat exchange element 100 from the right end and then flows out from the left end of the first heat exchange element 100.

[0117] The second heat exchange space 210 refers to the cavity space constructed in the second heat exchange element 200 and for the heat exchange medium to flow. When the heat exchange medium flows in the second heat exchange space 210, heat is exchanged with the battery unit through the second heat exchange element 200 to achieve heat exchange of the battery unit.

[0118] The second inflow end 220 refers to one of the two opposite ends of the second heat exchange element 200. For example, as shown in Figure 4, one of the two opposite ends of the second heat exchange element 200 distributed along the length direction, that is, the second inflow end 220 is the left end of the second heat exchange element 200.

[0119] The second outflow end 230 refers to the other end of the two opposite ends of the second heat exchange element 200. For example, as shown in Figure 4, the other end of the two opposite ends of the second heat exchange element 200 distributed along the length direction, that is, the second outflow end 230 is the right end of the second heat exchange element 200.

[0120] The second inlet end 220 and the second outlet end 230 are both connected to the second heat exchange space 210; it can be understood that after the heat exchange medium flows into the second heat exchange space 210 from the second inlet end 220, and then passes through the second heat exchange space 210 and exchanges heat with the battery unit, it flows out of the second heat exchange element 200 from the second outlet end 230. That is to say, for example, as shown in combination with Figures 4 and 5, the heat exchange medium flows into the second heat exchange element 200 from the left end and then flows out from the right end of the second heat exchange element 200.

[0121] The first inflow end 111 and the second outflow end 230 are located on the same side of the first heat exchanger 100, and the second inflow end 220 and the first outflow end 131 are located on the other side of the first heat exchanger 100; for example, as shown in Figures 4 and 5, the first inflow end 111 and the second outflow end 230 are located on the right side of the first heat exchanger 100, and the second inflow end 220 and the first outflow end 131 are located on the left side of the first heat exchanger 100.

[0122] The inflow pipe assembly 300 refers to a pipe assembly through which the heat exchange medium flows before flowing into the first inflow end 111 and the second inflow end 220 .

[0123] The outflow pipe assembly 400 refers to a pipe assembly through which the heat exchange medium flows after flowing out from the first outflow end 131 and the second outflow end 230 .

[0124] The first inflow end 111 and the second inflow end 220 are both connected to the inflow pipe assembly 300; the first outflow end 131 and the second outflow end 230 are both connected to the outflow pipe assembly 400. It is understood that a portion of the heat exchange medium flowing out of the inflow pipe assembly 300 flows into the first inflow end 111, then enters the first heat exchange space 1001, exchanges heat with one side of the battery cell, then flows into the outflow pipe assembly 400 through the first outflow end 131, and finally flows out through the outflow pipe assembly 400; another portion may flow into the second inflow end 220, then enter the second heat exchange space 210, exchange heat with the other side of the battery cell, then flow into the outflow pipe assembly 400 through the second outflow end 230, and finally flows out through the outflow pipe assembly 400. The heat exchange medium can be a medium with good thermal conductivity and good fluidity, such as water, air, or coolant.

[0125] In the heat exchange assembly 1 of the embodiment of the present application, when working, a row of battery cells is located between the adjacent first heat exchange element 100 and the second heat exchange element 200, and part of the heat exchange medium flowing out of the inflow pipe assembly 300 flows into the first inflow end 111, then flows into the first heat exchange space 1001 and exchanges heat with one side of the battery cell, and finally flows out through the first outflow end 131 and the outflow pipe assembly 400; at the same time, another part of the heat exchange medium flows into the second inflow end 220, then flows into the second heat exchange space 210 and exchanges heat with the other side of the battery cell, and finally flows out through the second outflow end 230 and the second outflow pipe 420, thus completing the heat exchange of a row of battery cells; in this process, the heat exchange medium in the first heat exchange element 100 flows from the first inflow end 111 to the first outflow end 131, and the heat exchange medium in the second ... The heat exchange medium in the heat element 200 flows from the second inlet end 220 to the second outlet end 230. Since the first inlet end 111 and the second outflow end 230 are located on the same side of the first heat exchange element 100, the second inlet end 220 and the first outflow end 131 are located on the other side of the first heat exchange element 100. Therefore, the flow direction of the heat exchange medium in the first heat exchange element 100 is opposite to the flow direction of the heat exchange medium in the second heat exchange medium 200. The heat exchange effect on one side of this row of battery cells decreases from the first inlet end 111 to the first outflow end 131, and the heat exchange effect on the other side increases from the first inlet end 111 to the first outflow end 131, so that the comprehensive heat exchange effect of a row of battery cells is uniformed, thereby improving the temperature difference between the battery cells in the same row of battery cells and improving the performance of the battery.

[0126] In another embodiment of the present application, in combination with Figures 4, 5, 6 and 11, the first outflow end 131 of the heat exchange component 1 provided is higher than the first inflow end 111; and / or, the second outflow end 230 is higher than the second inflow end 220.

[0127] In one possible design, as shown in Figure 6, the first outflow end 131 is higher than the first inflow end 111. It can be understood that the first outflow end 131 is located above the first inflow end 111. Such a design is beneficial for the liquid heat exchange medium to be discharged upward when it flows in the first heat exchange element 100, thereby helping to improve the heat exchange efficiency of the first heat exchange element 100.

[0128] In another possible design, as shown in Figure 7, the second outflow end 230 is higher than the second inflow end 220. It can be understood that the second outflow end 230 is located above the second inflow end 220. Such a design is beneficial for the liquid heat exchange medium to be discharged upward when it flows in the second heat exchange element 200, thereby helping to improve the heat exchange efficiency of the second heat exchange element 200.

[0129] In another possible design, as shown in Figures 4 and 5, the first outflow end 131 is higher than the first inflow end 111; the second outflow end 230 is higher than the second inflow end 220; this design is beneficial to the discharge of gas in the liquid heat exchange medium in the first heat exchange element 100 and the second heat exchange element 200, thereby helping to improve the heat exchange efficiency of the first heat exchange element 100 and the second heat exchange element 200.

[0130] In another embodiment of the present application, in combination with Figures 6, 8, 11 and 13, the first heat exchange component 100 and the second heat exchange component 200 of the heat exchange assembly 1 are rotationally symmetrical.

[0131] The first heat exchange element 100 is rotationally symmetrical to the second heat exchange element 200; it can be understood that the structure of the first heat exchange element 100 is the same as the structure of the second heat exchange element 200, and the second heat exchange element 200 can be obtained by rotating the first heat exchange element 100 around a straight line. For example, as shown in Figures 8 and 13, after the first heat exchange element 100 is rotated 180° around the center line EE, a heat exchange element identical to the second heat exchange element 200 can be obtained, wherein the center line EE refers to the equidistant line from the first inlet end 111 and the first outflow end 131, that is, the distance between the center line EE and the first inflow end 111 is equal to the distance between the center line EE and the first outflow end 131.

[0132] In the heat exchange assembly 1 of the embodiment of the present application, the structure of the first heat exchange element 100 is the same as that of the second heat exchange element 200, which increases the versatility of the components and reduces the difficulty and cost of production. In addition, the heat exchange medium flows in the first heat exchange element 100 and the second heat exchange element 200 in the same manner, so the heat exchange effects on the opposite sides of the same row of battery cells are the same and symmetrical. In this way, the heat exchange effects of the battery cells on the left and right sides of the same row of battery cells are the same, and the comprehensive heat exchange effects of each battery cell are similar or the same, which better improves the temperature difference effect of the battery cells in the same row, which is beneficial to improving the performance of the battery. In addition, the flow distribution of the heat exchange medium in the first heat exchange element 100 is also completely symmetrical with the flow distribution of the second heat exchange element 200. In this way, for the battery cells in the same row between the adjacent first heat exchange elements 100 and the second heat exchange element 200, the total flow of the heat exchange medium on the opposite sides of each battery cell is similar, so the heat exchange effect of each battery cell in the same row is basically the same, thereby effectively improving the temperature difference between the battery cells in the same row.

[0133] 8 and 13 , the heat exchange medium in the first heat exchange element 100 flows from right to left, and the heat exchange medium in the second heat exchange element 200 flows from left to right. In this way, the flow directions of the heat exchange media on opposite sides of the same row of battery cells are opposite, thereby reducing the temperature difference between the battery cells.

[0134] The following description will be made by taking the first heat exchange element 100 as an example.

[0135] In another embodiment of the present application, in combination with Figures 7 and 8, a first heat exchange element 100 is provided, which includes a first fluid collector 110, a heat exchange body 120 and a second fluid collector 130. The heat exchange body 120 is connected between the first fluid collector 110 and the second fluid collector 130. A first heat exchange space 1001 is constructed in the heat exchange body 120. The first fluid collector 110 is constructed with an inlet channel 112 and a first inlet end 111. The second fluid collector 130 is constructed with an outlet channel 132 and a first outflow end 131. The inlet channel 112 connects the first inflow end 111 and the first heat exchange space 1001, and the outflow channel 132 connects the first outflow end 131 and the first heat exchange space 1001.

[0136] The first current collector 110 , as shown in FIG. 4 and FIG. 6 , refers to a component connecting the first heat exchange element 100 and the inlet pipe assembly 300 .

[0137] The inlet channel 112 refers to a channel disposed in the first current collector 110 .

[0138] The second current collector 130 , as shown in FIG. 4 and FIG. 6 , refers to a component connecting the first heat exchange element 100 and the outflow pipe assembly 400 .

[0139] The outflow channel 132 refers to a channel disposed in the second current collector 130 .

[0140] The heat exchanger 120 refers to a component located between the first current collector 110 and the second current collector 130. It can be understood that the first current collector 110 and the second current collector 130 are located on opposite sides of the first heat exchange member 100, respectively.

[0141] The inflow channel 112 connects the first inflow end 111 and the first heat exchange space 1001, and the outflow channel 132 connects the first outflow end 131 and the first heat exchange space 1001; it can be understood that the heat exchange medium flowing out of the first inflow end 111 flows into the inflow channel 112, then flows into the first heat exchange space 1001 for heat exchange, and then flows into the first outflow end 131 through the outflow channel 132, and finally flows out through the first outflow end 131, thereby realizing the flow of the heat exchange medium in the first heat exchange element 100.

[0142] In the heat exchange assembly 1 of the embodiment of the present application, the first heat exchange member 100 adopts a structure of a first current collector 110, a heat exchange body 120 and a second current collector 130, which has a simple structure and is easy to process and manufacture.

[0143] In another embodiment of the present application, in combination with Figures 6 and 8, the first heat exchange space 1001 of the heat exchange component 1 is provided with a plurality of heat exchange channels 122 for connecting the inlet channel 112 and the outlet channel 132, and the inlet channel 112, the heat exchange channel 122 and the outlet channel 132 are arranged along the height direction of the first heat exchange member 100; the inlet channel 112 extends from the first inlet end 111 along the length direction of the first heat exchange member 100 and toward the first outflow end 131, and the outflow channel 132 extends from the first outflow end 131 along the length direction of the first heat exchange member 100 and toward the first inflow end 111, and the plurality of heat exchange channels 122 are arranged at intervals along the length direction of the first heat exchange member 100.

[0144] The heat exchange channel 122 refers to a channel formed in the heat exchange body 120 . For example, as shown in FIG. 8 , a plurality of spaced partitions 123 are provided in the first heat exchange space 1001 , and the heat exchange channel 122 refers to a channel formed between two adjacent partitions 123 .

[0145] The heat exchange channel 122 connects the inlet channel 112 and the outlet channel 132; it can be understood that the heat exchange medium flowing out from the first inlet end 111 flows into the inlet channel 112 and is then divided into multiple streams. The multiple streams of heat exchange medium flow into each heat exchange channel 122 one by one and flow into the outlet channel 132 through each heat exchange channel 122 and merge, and finally flow out from the first outlet end 131, realizing the flow of the heat exchange medium in the first heat exchange element 100; and the setting of multiple heat exchange channels 122 divides the heat exchange medium into multiple streams, thereby increasing the heat exchange area between the heat exchange medium and the first heat exchange element 100, which is beneficial to improving the heat exchange effect of the battery unit.

[0146] The inlet channel 112, the heat exchange channel 122, and the outlet channel 132 are arranged along the height direction of the first heat exchange element 100. It is understood that the inlet channel 112, the heat exchange channel 122, and the outlet channel 132 are arranged sequentially from bottom to top or from top to bottom. Of course, in other embodiments, the inlet channel 112, the heat exchange channel 122, and the outlet channel 132 can also be arranged sequentially from left to right or from right to left.

[0147] The inlet channel 112 extends from the first inlet end 111 along the length direction of the first heat exchange element 100 and toward the first outlet end 131 . For example, as shown in FIG. 8 , the inlet channel 112 extends from left to right until it communicates with the first inlet end 111 on the left.

[0148] The outflow channel 132 extends from the first outflow end 131 along the length direction of the first heat exchange element 100 and toward the first inflow end 111. For example, as shown in FIG. 8 , the outflow channel 132 extends from right to left until it communicates with the first outflow end 131 on the right side.

[0149] Multiple heat exchange channels 122 are arranged at intervals along the length direction of the first heat exchange element 100. For example, as shown in Figure 8, the heat exchange channels 122 are arranged at intervals from left to right or from right to left, and the two ends of the heat exchange channels 122 are respectively connected to the inlet channel 112 and the outlet channel 132.

[0150] When the heat exchange assembly 1 of the embodiment of the present application is working, the heat exchange medium flowing out from the first inlet end 111 flows into the inlet channel 112, and flows along the length direction of the first heat exchange element 100 in the inlet channel 112. During the flow, the heat exchange medium gradually enters each heat exchange channel 122, and then exchanges heat with the battery unit while flowing along each heat exchange channel 122, and then flows into the outflow channel 132 and merges, and finally flows out from the first outflow end 131, thus realizing the flow of the heat exchange medium in the first heat exchange element 100. In this flow process, the heat exchange medium can It flows along the entire length direction of the first heat exchange element 100, so that it can exchange heat with all battery cells in the same row of battery cells; in addition, in specific applications, the heat exchange medium in the inflow channel 112 may not exchange heat with the battery cells or may exchange heat with the battery cells in a small amount, so that the initial temperature of the heat exchange medium flowing from the inflow channel 112 into each heat exchange channel 122 is the same or has little difference, and the initial temperature of the heat exchange medium that exchanges heat with each battery cell in the same row of battery cells is the same or has little difference, thereby effectively improving the temperature difference between the battery cells in the same row of battery cells.

[0151] In addition, it should be noted that since the structure of the first heat exchange element 100 is the same as that of the second heat exchange element 200, similarly, the temperature of the heat exchange medium flowing into each heat exchange channel 122 through the inflow channel 112 in the second heat exchange element 200 is the same or has little difference, thereby more effectively improving the temperature difference between the battery cells in the same row of battery cells.

[0152] In another embodiment of the present application, as shown in FIG. 7 and FIG. 8 , the heat exchange channel 122 of the heat exchange assembly 1 is provided to extend along the height direction of the first heat exchange element 100 .

[0153] The heat exchange channel 122 extends along the height direction of the first heat exchange element 100; for example, as shown in FIG8 , the heat exchange channel 122 extends vertically, the structure of the first heat exchange element 100 is regular, and the processing and manufacturing of the first heat exchange element 100 is simple.

[0154] Of course, in other embodiments, the heat exchange channel 122 may also be arranged to extend obliquely.

[0155] In another embodiment of the present application, as shown in FIG8 , the widths H of the multiple heat exchange channels 122 of the heat exchange component 1 are the same.

[0156] The width of the heat exchange channel 122 , for example, as shown in FIG. 8 , the width H of the heat exchange channel 122 may refer to the distance between two adjacent partitions 123 .

[0157] The widths of the plurality of heat exchange channels 122 are the same; it is understandable that the plurality of partitions 123 are evenly spaced apart and arranged in the heat exchange body 120 .

[0158] In the heat exchange assembly 1 of the embodiment of the present application, the width H of the plurality of heat exchange channels 122 is the same, and the structure of the first heat exchange element 100 is regular, which is convenient for processing and manufacturing.

[0159] As shown in Figure 8, in the first heat exchange element 100, the heat exchange medium flowing in from the first inlet end 111 flows into the inlet channel 112 and flows from right to left along the inlet channel 112. In the process of the heat exchange medium flowing from right to left in the inlet channel 112, the heat exchange medium will be divided into multiple streams and flow into each heat exchange channel 122 one by one and exchange heat with the battery cells, and then flow out from the outflow channel 132. The flow path of the heat exchange medium in the first heat exchange element 100 can be referred to the path shown by the hollow arrow in Figure 8. However, the closer the heat exchange medium enters the heat exchange channel 122 to the first inflow end 111, the smaller the resistance is, and the closer the heat exchange medium enters the heat exchange channel 122 to the first outflow end 131, the greater the resistance is. Therefore, the closer to the first inflow end 111, the more heat exchange medium is in the heat exchange channel 122, and the closer to the first outflow end 131, the less heat exchange medium is in the heat exchange channel 122. In other words, the flow distribution of the heat exchange medium in the heat exchange channel 122 in the first heat exchange element 100 is more on the right and less on the left.

[0160] Since the first heat exchange element 100 and the second heat exchange element 200 are rotationally symmetrical, the structure of the second heat exchange element 200 is as follows: As shown in Figures 12 and 13, in the second heat exchange element 200, the heat exchange medium flowing in from the second inlet end 220 flows into the inlet channel 112 and flows from left to right along the inlet channel 112. In the process of the heat exchange medium flowing from left to right in the inlet channel 112, the heat exchange medium will be divided into multiple streams and flow into each heat exchange channel 122 one by one and exchange heat with the battery unit, and then flow out through the second outflow end 230; wherein, the flow path of the heat exchange medium in the second heat exchange element 200 can refer to the path shown by the hollow arrow in Figure 13. However, the closer the heat exchange medium enters the heat exchange channel 122 to the second inlet end 220, the smaller the resistance is, and the closer the heat exchange medium enters the heat exchange channel 122 to the second outlet end 230, the greater the resistance is. Therefore, the closer to the second inlet end 220, the more heat exchange medium is in the heat exchange channel 122, and the closer to the second outlet end 230, the less heat exchange medium is in the heat exchange channel 122. In other words, the flow distribution of the heat exchange medium in the heat exchange channel 122 in the second heat exchange element 200 is more on the left and less on the right.

[0161] The flow distribution of the heat exchange medium in the first heat exchange element 100 is more on the right and less on the left, and the flow distribution of the heat exchange medium in the second heat exchange element 200 is more on the left and less on the right. In this way, for the battery cells in the same row between the adjacent first heat exchange elements 100 and the second heat exchange elements 200, the total flow of the heat exchange medium on the opposite sides of each battery cell is similar, and the initial temperature of the heat exchange medium flowing into each heat exchange channel 122 of the first heat exchange element 100 is the same or has little difference, and the initial temperature of the heat exchange medium flowing into each heat exchange channel 122 of the second heat exchange element 200 is the same or has little difference, so the heat exchange effect of each battery cell in the same row is basically the same, thereby effectively improving the temperature difference between the battery cells in the same row.

[0162] In another embodiment of the present application, in combination with Figure 8, a blocking piece 510 is provided in part of the heat exchange channel 122 of the heat exchange component 1, and the blocking piece 510 blocks the heat exchange channel 122; the heat exchange body 120 is divided into multiple heat exchange sections 121, and the heat exchange sections 121 are arranged along the length direction of the first heat exchange element 100; in the flow direction of the heat exchange medium flowing into the flow channel 112, the number of blocking pieces 510 in the heat exchange section 121 gradually decreases.

[0163] The blocking member 510 refers to a component that blocks the heat exchange channel 122. When the heat exchange channel 122 is blocked by the blocking member 510, the heat exchange medium cannot flow from the heat exchange channel 122 into the outflow channel 132. Specifically, the blocking member 510 may be, but is not limited to, a plug or a blocking plate horizontally arranged in the heat exchange channel 122.

[0164] It can be understood that some of the heat exchange channels 122 in the first heat exchange element 100 are provided with blocking parts 510, while other parts of the heat exchange channels 122 are not provided with blocking parts 510. The heat exchange channels 122 without blocking parts 510 can connect the inlet channel 112 and the outlet channel 132.

[0165] The heat exchanger 120 is divided into a plurality of heat exchange segments 121, which are arranged along the length of the first heat exchange element 100. As shown in FIG8 , a heat exchange segment 121 refers to the projected area of ​​the corresponding battery cell in the corresponding row of battery cells projected onto the heat exchanger 120 along the Y direction, and each heat exchange segment 121 corresponds to each battery cell in the corresponding row of battery cells. In another embodiment, a heat exchange segment 121 may also refer to one of the multiple segments into which the heat exchanger 120 is divided along the length of the first heat exchange element 100 according to a preset length. The specific length can be selected based on actual needs and is not limited here. Of course, the segments can be divided at equal or unequal intervals, which is not limited here.

[0166] The flow direction of the heat exchange medium in the inflow channel 112 , for example, is the direction indicated by the hollow arrow in the inflow channel 112 in FIG. 8 , and can also refer to the negative direction of the X-axis in FIG. 8 .

[0167] It should be noted here that the more sealing parts 510 there are in the heat exchange section 121, the greater the resistance of the heat exchange medium in the flow channel 112 to flow into the heat exchange channel 122 in the heat exchange section 121. The greater the resistance, the more heat exchange medium will flow into the subsequent heat exchange channel 122.

[0168] In the heat exchange component 1 of the embodiment of the present application, since the number of sealing parts 510 in the heat exchange section 121 gradually decreases in the flow direction of the heat exchange medium in the inflow channel 112, the resistance of the heat exchange medium to the heat exchange channel 122 on the left side is reduced in the flow direction of the heat exchange medium in the inflow channel 112 from right to left. Therefore, the heat exchange medium flowing into the heat exchange channel 122 on the right side can be reduced, and more heat exchange medium will flow into the heat exchange channel 122 on the left side, thereby improving the situation in which the heat exchange medium flow distribution in the heat exchange channel 122 of the first heat exchange component 100 is more on the right and less on the left, improving the uniformity of the heat exchange medium flow distribution in the heat exchange body 120, and improving the temperature difference between battery cells in the same row.

[0169] In addition, since the first heat exchange element 100 and the second heat exchange element 200 are rotationally symmetrical, the arrangement of the sealing member 510 in the first heat exchange element 100 is symmetrical with the arrangement of the sealing member 510 in the second heat exchange element 200, so as to ensure that the total flow rate of the heat exchange medium participating in the heat exchange on both sides of each battery cell in the same row is basically similar, and the heat exchange effect between each battery cell and the heat exchange medium is basically the same, thereby improving the temperature difference between the battery cells in the same row.

[0170] In another embodiment of the present application, as shown in FIG8 , the blocking members 510 in at least one heat exchange section 121 of the heat exchange assembly 1 are evenly spaced.

[0171] The blocking pieces 510 in at least one heat exchange section 121 are arranged at even intervals. It can be understood that the blocking pieces 510 in the heat exchange section 121 are arranged at even intervals. In a heat exchange body 120, there can be one heat exchange section 121 with blocking pieces 510 that are evenly spaced, or there can be other heat exchange sections 121 with blocking pieces 510 that are evenly spaced; that is, the blocking pieces 510 in some heat exchange sections 121 in the heat exchange body 120 can be evenly spaced, or the blocking pieces 510 in all heat exchange sections 121 can be evenly spaced. In addition, the blocking pieces 510 are evenly spaced, and it can be understood that the spacing between two adjacent blocking pieces 510 is the same.

[0172] In the heat exchange assembly 1 of the embodiment of the present application, the blocking members 510 are evenly distributed, which facilitates processing and manufacturing.

[0173] In another embodiment of the present application, as shown in combination with FIG. 10 and FIG. 15 , the heat exchange component 1 is provided, in which the width H of the heat exchange channel 122 gradually increases in the flow direction of the heat exchange medium flowing into the flow channel 112 .

[0174] In the flow direction of the heat exchange medium in the inflow channel 112, the width H of the heat exchange channel 122 gradually increases. For example, as shown in Figure 10, in the first heat exchange element 100, the width H of the heat exchange channel 122 gradually increases from right to left. It should be noted that the larger the spacing between the heat exchange channels 122, the smaller the resistance of the heat exchange medium flowing into the heat exchange channel 122, and the easier it is to flow into the heat exchange channel 122. Therefore, when the heat exchange medium flows from right to left along the inflow channel 112, the resistance of the heat exchange medium flowing into the heat exchange channel 122 on the left is reduced, so that the heat exchange medium flowing into the heat exchange channel 122 on the right can be reduced, and more heat exchange medium will flow into the heat exchange channel 122 on the left, thereby improving the heat exchange medium flow distribution in the heat exchange channel 122 of the first heat exchange element 100, which is more on the right and less on the left, improving the uniformity of the heat exchange medium flow distribution in the heat exchange body 120, and improving the temperature difference between battery cells in the same row.

[0175] Similarly, in combination with Figure 15, in the second heat exchange element 200, the width H of the heat exchange channel 122 gradually increases from left to right; it should be noted here that the larger the spacing between the heat exchange channels 122, the smaller the resistance of the heat exchange medium flowing into the heat exchange channel 122, and it is easier to flow into the heat exchange channel 122. Therefore, when the heat exchange medium flows from left to right along the inlet channel 112, the resistance of the heat exchange medium flowing into the heat exchange channel 122 on the right is reduced, then the heat exchange medium flowing into the heat exchange channel 122 on the left can be reduced, and at the same time, more heat exchange medium will flow into the heat exchange channel 122 on the right, thereby improving the situation where the heat exchange medium flow distribution in the heat exchange channel 122 of the second heat exchange element 200 is more on the left and less on the right, improving the uniformity of the heat exchange medium flow distribution in the heat exchange body 120, and improving the temperature difference between battery cells in the same row.

[0176] In addition, since the first heat exchange element 100 and the second heat exchange element 200 are rotationally symmetrical, the spacing distribution of the heat exchange channels 122 in the first heat exchange element 100 is symmetrical with the spacing distribution of the heat exchange channels 122 in the second heat exchange element 200, thereby ensuring that the total flow rate of the heat exchange medium participating in the heat exchange on both sides of each battery cell in the same row is basically similar, ensuring that the heat exchange effect between each battery cell and the heat exchange medium is basically consistent, thereby improving the temperature difference between the battery cells in the same row.

[0177] In another embodiment of the present application, as shown in FIG6 and FIG8 , the outflow channel 132 of the heat exchange component 1 is provided to be located above the heat exchange channel 122 , and the inflow channel 112 is located below the heat exchange channel 122 .

[0178] The outflow channel 132 is located above the heat exchange channel 122, and the inflow channel 112 is located below the heat exchange channel 122. It can be understood that, in conjunction with FIG8 , the outflow channel 132, the heat exchange channel 122, and the inflow channel 112 are arranged sequentially from top to bottom. This design allows the liquid heat exchange medium to flow from bottom to top, which is beneficial for the discharge of gas in the liquid heat exchange medium and helps improve the heat exchange efficiency of the first heat exchange element 100.

[0179] In another embodiment of the present application, as shown in FIG10 , the first current collector 110 and the heat exchange body 120 of the provided heat exchange assembly 1 are split structures; and / or the second current collector 130 and the heat exchange body 120 are split structures.

[0180] In a possible design, the first current collector 110 and the heat exchanger 120 are separate structures.

[0181] The first current collector 110 and the heat exchanger 120 are split structures. It can be understood that the first current collector 110 and the heat exchanger 120 are connected by a connecting structure, which can be a screw structure, a snap structure, an adhesive structure, a magnetic adsorption structure, or other structures that can connect and fix the two components; in addition, during the production of the first heat exchanger 100, the inflow channel 112 and the heat exchange channel 122 are processed on the first current collector 110 and the heat exchanger 120 respectively, and after the processing is completed, the first current collector 110 and the heat exchanger 120 are assembled together to obtain the first heat exchanger 100; with this split structure, the processing difficulty of the inflow channel 112 and the heat exchange channel 122 is low, and the processing and production of the first heat exchanger 100 is simple and convenient.

[0182] In another possible design, the second current collector 130 and the heat exchanger 120 are separate structures.

[0183] The second fluid collector 130 and the heat exchanger 120 are split structures. It can be understood that the second fluid collector 130 and the heat exchanger 120 are connected by a connecting structure, which can be a screw structure, a snap structure, an adhesive structure, a magnetic adsorption structure, or other structures that can connect and fix the two components; in addition, during the production of the first heat exchanger 100, the outflow channel 132 and the heat exchange channel 122 are processed on the second fluid collector 130 and the heat exchanger 120 respectively, and after the processing is completed, the second fluid collector 130 and the heat exchanger 120 are assembled together to obtain the first heat exchanger 100; with this split structure, the processing difficulty of the outflow channel 132 and the heat exchange channel 122 is low, and the processing and production of the first heat exchanger 100 is simple and convenient.

[0184] In another possible design, the first current collector 110 and the heat exchanger 120 are split structures, and the second current collector 130 and the heat exchanger 120 are split structures.

[0185] In the heat exchange assembly 1 of the embodiment of the present application, during the production of the first heat exchange component 100, the inlet flow channel 112, the heat exchange channel 122 and the outlet flow channel 132 are respectively processed on the first collector 110, the heat exchange body 120 and the second collector 130. After the processing is completed, the first collector 110, the second collector 130 and the heat exchange body 120 are assembled together to obtain the first heat exchange component 100; with this split structure, the processing difficulty of the inlet flow channel 112, the outflow flow channel 132 and the heat exchange channel 122 is low, and the processing and production of the first heat exchange component 100 is simple and convenient.

[0186] In another embodiment of the present application, as shown in Figure 10, the end of the first current collector 110 of the heat exchange assembly 1 provided protrudes out of the heat exchange body 120 to form a first inflow end 111; and / or, the end of the second current collector 130 protrudes out of the heat exchange body 120 to form a first outflow end 131.

[0187] In one possible design, the end of the first current collector 110 protrudes out of the heat exchanger 120 to form a first inlet end 111. For example, as shown in Figures 4, 5 and 6, the right end of the first current collector 110 protrudes out of the right side of the heat exchanger 120 to form the first inlet end 111. The space above the first inlet end 111 can accommodate the outflow pipe assembly 400, which can reduce the volume of the heat exchange assembly 1 and help improve the energy density of the battery.

[0188] In another possible design, the portion of the second current collector 130 that protrudes beyond the heat exchanger 120 forms the first outflow end 131. For example, referring to Figures 4, 5, and 6, the portion of the left end of the first current collector 110 that protrudes beyond the left side of the heat exchanger 120 forms the first outflow end 131. This allows the space below the first outflow end 131 to accommodate the inflow pipe assembly 300, reducing the volume of the heat exchange assembly 1 and facilitating improved battery energy density.

[0189] In another possible design, the portion of the end of the first current collector 110 that protrudes outside the heat exchanger 120 forms the first inlet end 111; the portion of the end of the second current collector 130 that protrudes outside the heat exchanger 120 forms the first outlet end 131. For example, referring to Figures 4, 5, and 6, the portion of the right end of the first current collector 110 that protrudes outside the right side of the heat exchanger 120 is the first inlet end 111, and the portion of the left end of the first current collector 110 that protrudes outside the left side of the heat exchanger 120 is the first outlet end 131. In this way, the space above the first inlet end 111 can accommodate the outlet pipe assembly 400, and the space below the first outlet end 131 can accommodate the inlet pipe assembly 300. Furthermore, the volume of the heat exchange assembly 1 can be reduced, which is beneficial for improving the energy density of the battery.

[0190] It should be noted that the above embodiments are specifically described using the structure of the first heat exchanger 100 as an example. In other embodiments, it is understandable that by designing the structures of the first heat exchanger 100 and the second heat exchanger 200 to be identical, and rotating the first heat exchanger 100 180° around EE, a heat exchanger with the same structure as the second heat exchanger 200 can be obtained, thereby ensuring that the heat exchange effects on the left and right sides of the same row of battery cells are exactly the same. This will not be described in detail here. Of course, in other embodiments, the first heat exchanger 100 and the second heat exchanger 200 may also adopt different structures. Their specific structures can be set according to actual needs and are not limited here.

[0191] In another embodiment of the present application, in combination with Figures 4 and 5, the inlet pipe assembly 300 of the heat exchange component 1 provided includes a first inlet pipe 310 and a second inlet pipe 320, the first inlet pipe 310 is connected to the first inlet end 111, and the second inlet pipe 320 is connected to the second inlet end 220.

[0192] The first inflow pipe 310 refers to a pipe through which the heat exchange medium flows before flowing into the first inflow end 111 .

[0193] The second inflow pipe 320 refers to a pipe through which the heat exchange medium flows before flowing into the second inflow end 220 .

[0194] In the heat exchange component 1 of the embodiment of the present application, the first inflow end 111 and the second inflow end 220 are located on opposite sides of the heat exchange component 1, and the heat exchange medium flows out of the first inflow pipe 310 and flows into each first inflow end 111, and the second inflow pipe 320 flows into each second inflow end 220. The first heat exchange element 100 and the second heat exchange element 200 are supplied with flow separately, which facilitates the pipeline distribution of the inflow pipe assembly 300.

[0195] In another embodiment of the present application, in combination with Figures 4 and 5, the heat exchange component 1 provided is multiple in number with respect to the first heat exchange elements 100, and multiple in number with respect to the second heat exchange elements 200; the alternating arrangement direction of the first heat exchange elements 100 and the second heat exchange elements 200 is the first direction (see the Y direction); the first inflow pipe 310 extends along the first direction and is sequentially connected to each first inflow end 111; the second inflow pipe 320 extends along the first direction and is sequentially connected to each second inflow end 220.

[0196] There are multiple first heat exchange elements 100. It can be understood that in a heat exchange component 1, the number of first heat exchange elements 100 is two, three or more than four. For example, as shown in Figures 4 and 5, the number of first heat exchange elements 100 is five.

[0197] There are multiple second heat exchange components 200. It can be understood that in a heat exchange assembly 1, the number of second heat exchange components 200 is two, three or more than four. For example, as shown in Figures 4 and 5, the number of second heat exchange components 200 is five.

[0198] The first direction, as shown in FIG. 4 and FIG. 5 , may refer to the Y direction, that is, the first heat exchange element 100 and the second heat exchange element 200 are alternately arranged along the Y direction.

[0199] The first inflow pipe 310 extends along a first direction and is sequentially connected to each first inflow end 111. It is understood that after the heat exchange medium flows into the first inflow pipe 310, it flows sequentially along the first direction into each first inflow end 111. As shown in Figures 4 and 5 , the first inflow pipe 310 is sequentially connected to each first inflow end 111 from front to back.

[0200] The second inflow pipe 320 extends along the first direction and is connected to each second inflow end 220 in sequence. It can be understood that after the heat exchange medium flows into the second inflow pipe 320, it flows into each second inflow end 220 in sequence along the first direction; as shown in Figures 4 and 5, the second inflow pipe 320 is connected to each second inflow end 220 in sequence from front to back.

[0201] In the heat exchange component 1 of the embodiment of the present application, the first inflow pipe 310 extends along the first direction and is connected to each first inflow end 111 in sequence. The layout of the first inflow pipe 310 is simple; similarly, the second inflow pipe 320 extends along the first direction and is connected to each second inflow end 220 in sequence. The layout of the second inflow pipe 320 is simple, which makes the processing and manufacturing of the heat exchange component 1 simple.

[0202] In another embodiment of the present application, in combination with Figures 4 and 5, the first inflow pipe 310 of the heat exchange component 1 provided is configured with a first inflow port 311, and a first inflow space 1111 is configured in the first inflow end 111. The first inflow space 1111 connects the first inflow pipe 310 and the first heat exchange space 1001. A first baffle 520 is provided in the first inflow space 1111 near the first inflow port 311. The first baffle 520 is used to increase the resistance of the heat exchange medium flowing into the first heat exchange space 1001; and / or, the second inflow pipe 320 is configured with a second inflow port 321, and a second inflow space 221 is configured in the second inflow end 220. The second inflow space 221 connects the second inflow pipe 320 and the second heat exchange space 210. A second baffle 530 is provided in the second inflow space 221 near the second inflow port 321. The second baffle 530 is used to increase the resistance of the heat exchange medium flowing into the second heat exchange space 210.

[0203] In one possible design, the first inflow pipe 310 is configured with a first inflow port 311, and a first inflow space 1111 is configured in the first inflow end 111. The first inflow space 1111 connects the first inflow pipe 310 and the first heat exchange space 1001. A first baffle 520 is provided in the first inflow space 1111 near the first inflow port 311. The first baffle 520 is used to increase the resistance of the heat exchange medium flowing into the first heat exchange space 1001.

[0204] The first inlet 311, it can be understood that the heat exchange medium can flow into the first inlet pipe 310 from the first inlet 311. For example, as shown in Figure 4, the first inlet 311 is an opening on the front end face of the first inlet pipe 310. After the heat exchange medium flows into the first inlet pipe 310 from the first inlet 311, it flows backward along the first inlet pipe 310 and flows into each first inlet end 111.

[0205] The first inflow space 1111 refers to a cavity space formed in the first inflow end 111 .

[0206] The first inflow space 1111 connects the first inflow pipe 310 and the first heat exchange space 1001. It can be understood that the heat exchange medium flowing in the first inflow pipe 310 can flow into the first inflow space 1111 and flow into the first heat exchange space 1001 through the first inflow space 1111, thereby realizing heat exchange of the battery unit.

[0207] A first baffle 520 is provided in the first inflow space 1111 near the first inflow port 311. For example, as shown in FIG4 , the first heat exchange elements 100 are arranged from front to back, and the first inflow ends 111 are also arranged from front to back. The second inflow space 221 near the first inflow port 311 may refer to the first inflow space 1111 of one or more first inflow ends 111 located in front. For example, the number of the first heat exchange elements 100 is five, and the first inflow spaces 1111 of the first three first inflow ends 111 are provided with the first baffle 520, and the first inflow spaces 1111 of the last two first inflow ends 111 are provided with the first baffle 520. The first inflow space 1111 may not have a first baffle 520 installed. Alternatively, the first inflow space 1111 of the first, first two, or first four first inflow ends 111 may have a first baffle 520 installed, while the first inflow spaces 1111 of the remaining first inflow ends 111 may not have a first baffle 520 installed. Alternatively, any one or any two of the first inflow spaces 1111 of the first three first inflow ends 111 may have a first baffle 520 installed, while the first inflow spaces 1111 of the remaining first inflow ends 111 may not have a first baffle 520 installed. Of course, in other embodiments, the number of first heat exchange elements 100 may also be two, three, four, or more than six, and the arrangement of the first baffle 520 may be selected according to actual conditions and is not limited here.

[0208] The first baffle 520 is used to increase the resistance of the heat exchange medium flowing into the first heat exchange space 1001. It can be understood that the first baffle 520 can reduce the flow area of ​​the heat exchange medium flowing through the first inflow space 1111, thereby increasing the resistance of the heat exchange medium flowing through the first inflow space 1111 and reducing the heat exchange medium flowing into the first heat exchange space 1001.

[0209] It should be noted here that, in the process of the heat exchange medium flowing from front to back along the first inlet pipe 310, the resistance of the heat exchange medium flowing into the first heat exchange space 1001 located on the front side is small, while the resistance of the heat exchange medium flowing into the first heat exchange space 1001 located on the rear side is large, so that the flow distribution of the heat exchange medium in the first heat exchange element 100 is more in the front and less in the back, and the flow rate of the heat exchange medium participating in the heat exchange between different rows of battery cells is different, resulting in a large temperature difference between different rows of battery cells.

[0210] The heat exchange component 1 of the embodiment of the present application increases the resistance of the heat exchange medium to the first heat exchange space 1001 located at the front side by setting a first baffle 520 in the first inflow space 1111 near the first inlet 311. In this way, more heat exchange medium will flow into the first heat exchange space 1001 located at the rear side, thereby improving the uneven distribution of the heat exchange medium before and after, improving the uniformity of the distribution of the heat exchange medium before and after, and improving the temperature difference between different rows of battery cells.

[0211] In another possible design, the second inflow pipe 320 is configured with a second inflow port 321, and a second inflow space 221 is configured in the second inflow end 220. The second inflow space 221 connects the second inflow pipe 320 and the second heat exchange space 210. A second baffle 530 is provided in the second inflow space 221 near the second inflow port 321. The second baffle 530 is used to increase the resistance of the heat exchange medium flowing into the second heat exchange space 210.

[0212] The second inlet 321, it can be understood that the heat exchange medium can flow into the second inlet pipe 320 from the second inlet 321. For example, as shown in Figure 4, the second inlet 321 is an opening on the front end face of the second inlet pipe 320. After the heat exchange medium flows into the second inlet pipe 320 from the second inlet 321, it flows from front to back along the second inlet pipe 320 and flows into each second inlet end 220.

[0213] The second inflow space 221 refers to a cavity space formed in the second inflow end 220 .

[0214] The second inflow space 221 connects the second inflow pipe 320 and the second heat exchange space 210. It can be understood that the heat exchange medium flowing in the second inflow pipe 320 can flow into the second inflow space 221 and flow into the second heat exchange space 210 through the second inflow space 221, thereby realizing heat exchange of the battery unit.

[0215] A second baffle 530 is provided in the second inflow space 221 near the second inflow inlet 321. For example, as shown in FIG4 , the second heat exchange elements 200 are arranged from front to back, and the second inflow ends 220 are also arranged from front to back. The second inflow space 221 near the second inflow inlet 321 may refer to the second inflow space 221 of one or more second inflow ends 220 located in the front. For example, the number of the second heat exchange elements 200 is five, and the second inflow spaces 221 of the first three second inflow ends 220 are provided with a second baffle 530, and the second inflow spaces 221 of the last two second inflow ends 220 are not provided with a second baffle 530. It may also be the front A second baffle 530 is provided in the second inflow space 221 of one, the first two or the first four second inflow ends 220, and no second baffle 530 is provided in the second inflow space 221 of the remaining second inflow ends 220; it can also be that any one or any two of the second inflow spaces 221 of the first three second inflow ends 220 are provided with a second baffle, and no second baffle 530 is provided in the second inflow space 221 of the remaining second inflow ends 220. The specific selection can be made according to actual conditions and is not limited here; in addition, the number of second heat exchange elements 200 can be two, three, four or more than five, which is not limited here.

[0216] The second baffle 530 is used to increase the resistance of the heat exchange medium flowing into the second heat exchange space 210. It can be understood that the second baffle 530 can reduce the flow area of ​​the heat exchange medium flowing through the second inflow space 221, thereby increasing the resistance of the heat exchange medium flowing through the second inflow space 221 and reducing the heat exchange medium flowing into the second heat exchange space 210.

[0217] It should be noted here that, in the process of the heat exchange medium flowing from front to back along the second inlet pipe 320, the resistance of the heat exchange medium flowing into the second heat exchange space 210 located on the front side is small, while the resistance of the heat exchange medium flowing into the second heat exchange space 210 located on the rear side is large, so that the flow distribution of the heat exchange medium in the front-to-back direction is more in the front and less in the rear, which will result in different flow rates of the heat exchange medium participating in the heat exchange between different rows of battery cells, resulting in large temperature differences between different rows of battery cells.

[0218] The heat exchange component 1 of the embodiment of the present application is capable of increasing the resistance of the heat exchange medium to the second heat exchange space 210 located at the front side by arranging a second baffle 530 in the second inlet space 221 near the second inlet 321. In this way, more heat exchange medium will flow into the second heat exchange space 210 located at the rear side, thereby improving the uneven distribution of the heat exchange medium in the front and rear, improving the uniformity of the distribution of the heat exchange medium in the front and rear, and improving the temperature difference between different rows of battery cells.

[0219] In another possible design, the first inflow pipe 310 is constructed with a first inflow port 311, and a first inflow space 1111 is constructed in the first inflow end 111. The first inflow space 1111 connects the first inflow pipe 310 and the first heat exchange space 1001. A first baffle 520 is provided in the first inflow space 1111 near the first inflow port 311. The first baffle 520 is used to increase the resistance of the heat exchange medium flowing into the first heat exchange space 1001; the second inflow pipe 320 is constructed with a second inflow port 321, and a second inflow space 221 is constructed in the second inflow end 220. The second inflow space 221 connects the second inflow pipe 320 and the second heat exchange space 210. A second baffle 530 is provided in the second inflow space 221 near the second inflow port 321. The second baffle 530 is used to increase the resistance of the heat exchange medium flowing into the second heat exchange space 210. Similarly, the heat exchange medium of the embodiment of the present application can simultaneously improve the uniformity of the front-to-back distribution of the heat exchange medium flowing through the first heat exchange element 100 and the heat exchange medium flowing through the second heat exchange element 200, improve the uniformity of the front-to-back distribution of the heat exchange medium in the entire heat exchange assembly 1, and more effectively improve the temperature difference between different rows of battery cells.

[0220] In another embodiment of the present application, as shown in FIG16 , the flow direction of the heat exchange medium in the first inflow pipe 310 of the heat exchange assembly 1 is opposite to the flow direction of the heat exchange medium in the second inflow pipe 320 .

[0221] The flow direction of the heat exchange medium in the first inflow pipe 310, for example, referring to FIG16 , is that the heat exchange medium in the first inflow pipe 310 flows from back to front, so that the flow distribution of the heat exchange medium flowing through the first heat exchange element 100 is less in the front and more in the back.

[0222] The flow direction of the heat exchange medium in the second inlet pipe 320, for example, as shown in Figure 16, the heat exchange medium in the first inlet pipe 310 flows from front to back, so that the flow distribution of the heat exchange medium flowing through the second heat exchange element 200 is more in the front and less in the back.

[0223] In the heat exchange assembly 1 of the embodiment of the present application, the flow direction of the heat exchange medium in the first inflow pipe 310 is opposite to the flow direction of the heat exchange medium in the second inflow pipe 320. The flow distribution of the heat exchange medium flowing through the first heat exchange element 100 is less in the front and more in the back, and the flow distribution of the heat exchange medium flowing through the second heat exchange element 200 is more in the front and less in the back. For different rows of battery cells, the total flow rate of the heat exchange medium flowing through the first heat exchange element 100 and the second heat exchange element 200 relative to each row of battery cells is similar, so the heat exchange effects of different rows of battery cells are basically the same, thereby improving the temperature difference between different rows of battery cells.

[0224] In another embodiment of the present application, in combination with Figure 16, the heat exchange component 1 provided also includes a connecting pipe 610, the first inflow pipe 310 is configured with a first inflow port, the first inflow port is for heat exchange medium to flow into the first inflow pipe 310, the second inflow pipe 320 is configured with a second inflow port 321, the second inflow port 321 is for heat exchange medium to flow into the second inflow pipe 320; one end of the connecting pipe 610 is connected to the first inflow port, and the other end of the connecting pipe 610 and the second inflow port 321 are located on the same side of the heat exchange component 1.

It can be understood that the heat exchange medium flows into the first inlet pipe 310 from the opening on the rear end face of the first inlet pipe 310 and flows forward along the first inlet pipe 310.

[0227] The second inlet 321, for example, as shown in Figure 16, the second inlet 321 is an opening opened on the front end surface of the second inlet end 220; the second inlet 321 is for the heat exchange medium to flow into the second inlet pipe 320. It can be understood that the heat exchange medium flows into the second inlet pipe 320 from the opening on the front end surface of the second inlet pipe 320 and flows backward along the second inlet pipe 320. In this way, the flow direction of the heat exchange medium in the first inlet pipe 310 is from back to front, and the flow direction of the heat exchange medium in the second inlet pipe 320 is from front to back, so that the flow direction of the heat exchange medium in the first inlet pipe 310 is opposite to the flow direction of the heat exchange medium in the second inlet pipe 320.

[0228] One end of the connecting pipe 610 is connected to the first inlet. It can be understood that the heat exchange medium flows into the first inlet pipe 310 after flowing into the connecting pipe 610 .

[0229] In the heat exchange component 1 of the embodiment of the present application, since the other end of the connecting pipe 610 and the second inlet 321 are located on the same side of the heat exchange component 1, the heat exchange medium can be introduced into the connecting pipe 610 and the second inlet 321 from the same side of the heat exchange component 1, which facilitates the distribution of the pipelines and reduces the difficulty of assembly.

This design can reduce the space occupied by the first outflow pipe 410, the connecting pipe 610, and the second inflow pipe 320 in the length direction of the first heat exchange element 100, resulting in a compact structure of the heat exchange assembly 1 and improving the energy density of the battery.

[0236] The bent end 611 refers to a bent section on the connecting pipe 610, wherein the bent end 611 can be in the shape of a broken line, a curve, etc.; wherein, the bent end 611 is in the shape of a semicircular arc, so that the shape of the bent end 611 is smooth, and the heat exchange medium flows smoothly in the bent end 611; in addition, the regular shape also facilitates processing and manufacturing.
