Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the utility model.

[0044] See also Figure 1 , which is a three-dimensional schematic diagram of a partial structure of the heat exchange component proposed in the utility model. In this exemplary embodiment, the heat exchange component proposed in the utility model is described by taking the application to a vehicle-mounted battery as an example. It is easy for those skilled in the art to understand that in order to apply the relevant design of the utility model to other types of battery devices, various modifications, additions, substitutions, deletions or other changes are made to the specific embodiments described below, and these changes are still within the scope of the principle of the heat exchange component proposed in the utility model.

[0045] like Figure 1 As shown, in one embodiment of the present invention, the heat exchange component provided by the present invention is suitable for exchanging heat for a battery device, and the heat exchange component includes a main channel portion 110 and a diverter portion 120. Figure 2 and Figure 3 , Figure 2 A representative example is shown in Figure 1 3D exploded schematic diagram, in which a diversion portion 120 is separated from the main channel portion 110, and the relevant area is enlarged and displayed; Figure 3 Representatively shown in Figure 1 The following will be combined with the above drawings to explain in detail the structure, connection method and functional relationship of the main components of the heat exchange component proposed by the utility model.

[0046] like Figures 1 to 3 As shown, in one embodiment of the present invention, the main channel portion 110 has a first chamber 111 for accommodating a heat exchange medium. The flow divider 120 and the main channel portion 110 are relatively independent separate components, and at least a portion of the flow divider 120 is spliced ​​and connected to the main channel portion 110. Figures 1 to 3In the embodiment shown, the diverter 120 is completely spliced ​​to the main channel 110. When the main channel 110 is provided with an assembly groove 112, according to the different relationship between the diverter 120 and the assembly groove 112, it can also be not less than the above-mentioned design of full splicing connection. Figure 5 In the embodiment shown, the flow divider 120 is partially spliced ​​to the main channel portion 110. The flow divider 120 at least includes a first flow divider 1201, and the first flow divider 1201 is provided with a flow divider hole 121, and the flow divider hole 121 is connected to the first chamber 111. Accordingly, the flow divider hole 121 can allow the heat exchange medium to flow from the first chamber 111 to other locations, such as to Figure 7 The second chamber for accommodating the battery 300 is shown, and the flow to Figure 5 and Figure 8 The inner cavity of another main channel portion 110 is shown. Through the above structural design, since the function of the diverter portion 120 is to divert the heat exchange medium so that the heat exchange medium enters different spaces to realize heat exchange, the utility model adopts a design of splicing and connecting the main channel portion 110 and the diverter portion 120, which enables the heat exchange component to flexibly assemble the diverter portion 120 in a variety of schemes according to different heat exchange requirements, improves the flexible disassembly and replacement of the parts of the heat exchange component, and expands the application range of the heat exchange component. In addition, since the diverter portion 120 can be flexibly replaced, the utility model can select and replace the diverter portion 120 of multiple box structures, and there is no need to replace the main channel portion 110 when responding to different heat exchange requirements, which is conducive to reducing the mold opening cost of parts.

[0047] like Figure 2 As shown, in one embodiment of the present invention, the main channel portion 110 may be provided with an assembly groove 112, and the assembly groove 112 is connected to the first chamber 111 of the main channel portion 110. On this basis, the diverter portion 120 is at least partially accommodated in the assembly groove 112, so as to realize the splicing connection between the diverter portion 120 and the main channel portion 110. Through the above structural design, the present invention realizes the splicing connection between the main channel portion 110 and the diverter portion 120 by setting the assembly groove 112 in the main channel portion 110, which has a simple structure, is easy to process and assemble, and has a reliable connection.

[0048] like Figure 2As shown, based on the structural design that the main channel portion 110 is provided with an assembly groove 112, in one embodiment of the present utility model, a fitting structure 113 may be provided between the groove wall of the assembly groove 112 and the side wall of the portion of the diverter portion 120 accommodated in the assembly groove 112, and the fitting structure 113 includes a protrusion and a recess, that is, the protrusion may be provided on the groove wall of the assembly groove 112 or the side wall of the portion of the diverter portion 120 accommodated in the assembly groove 112, and the corresponding area of ​​the side wall or the groove wall may be provided with a recess that fits with the protrusion. Through the above structural design, the present utility model can use the fitting structure 113 to achieve the limitation of the main channel portion 110 and the diverter portion 120 in the direction parallel to the first surface 114, thereby improving the assembly connection effect of the main channel portion 110 and the diverter portion 120 and improving the assembly stability.

[0049] like Figure 2 As shown, based on the structural design that the interlocking structure 113 is provided between the groove wall of the assembly groove 112 and the side wall of the diverter 120, in one embodiment of the utility model, multiple groups of interlocking structures 113 can be provided between the groove wall of the assembly groove 112 and the side wall of the portion of the diverter 120 accommodated in the assembly groove 112, and the multiple groups of interlocking structures 113 are arranged at intervals along the circumference of the assembly groove 112. Through the above structural design, the utility model can further improve the assembly connection effect of the main channel portion 110 and the diverter 120, and further improve the assembly stability.

[0050] See also Figure 4 , Figure 4 1 represents an enlarged schematic diagram of a partial structure of a heat exchange component in another exemplary embodiment that can embody the principle of the present invention in a decomposed state, wherein specifically a diverter portion 120 is separated from a main channel portion 110 and a partial enlargement is performed.

[0051] like Figure 4 As shown, in one embodiment of the present invention, taking the structural design that the main channel portion 110 is provided with the assembly groove 112 as an example, a limited retaining wall 1121 can be provided at one end of the groove wall of the assembly groove 112 close to the first chamber 111, and a side surface portion of the diverter portion 120 facing the first chamber 111 abuts against the limited retaining wall 1121. Through the above structural design, the present invention can use the limited retaining wall 1121 to limit the main channel portion 110 and the diverter portion 120 in a direction perpendicular to the first surface 114, thereby improving the assembly connection effect of the main channel portion 110 and the diverter portion 120, improving the assembly stability, and preventing the diverter portion 120 from being excessively inserted into the assembly groove 112 and invading the first chamber 111.

[0052] Based on the structural design of the groove wall of the assembly groove 112 being provided with the limited retaining wall 1121, in an embodiment not shown in the figure of the present utility model, a limited step can be provided on the side surface of the diverter 120 facing the first chamber 111, and the limited step matches the shape of the limited retaining wall 1121, and the diverter 120 abuts against the limited retaining wall 1121 with the limited step. Through the above structural design, the present utility model can further optimize the limited matching effect between the diverter 120 and the limited retaining wall 1121, and further improve the assembly connection effect.

[0053] like Figure 1 and Figure 2 As shown, based on the structural design that the main channel portion 110 is provided with the assembly groove 112, in one embodiment of the present invention, the shunt portion 120 can be completely accommodated in the assembly groove 112. Through the above structural design, when the heat exchange component proposed by the present invention is applied to, for example, an immersion battery device, it can avoid that the shunt portion 120 occupies the space for accommodating the battery 300, which is conducive to improving the energy density of the battery device.

[0054] like Figure 1 and Figure 2 As shown, based on the structural design that the diverter 120 is completely accommodated in the assembly groove 112, in one embodiment of the present invention, the side surface of the diverter 120 facing away from the first chamber 111 can be flush with the side surface of the main channel portion 110 facing away from the first chamber 111 (for example, the first surface 114 shown in the figure). Through the above structural design, the present invention can ensure the flatness of the heat exchange component on the side of the first surface 114, and improve the structural integrity of the combination of the main channel portion 110 and the diverter 120. In some embodiments, the side surface of the diverter 120 facing away from the first chamber 111 can also be recessed relative to the side surface of the main channel portion 110 facing away from the first chamber 111, which is not limited to this embodiment.

[0055] See also Figure 5 , Figure 5 2 represents a three-dimensional exploded schematic diagram of a heat exchange component in another exemplary embodiment that can embody the principle of the present invention, in which a main flow channel portion 110 is separated.

[0056] Different from Figures 1 to 3 In the embodiment shown, the diverter 120 is completely accommodated in the assembly groove 112. Figure 5 As shown, in one embodiment of the present invention, when the main channel portion 110 is provided with an assembly groove 112 for assembling and connecting the diverter portion 120, the diverter portion 120 may also partially extend out of the assembly groove 112, and the diverter hole 121 extends to the portion of the diverter portion 120 extending out of the assembly groove 112, so that the portion of the diverter portion 120 extending out of the assembly groove 112 is a heat exchange structure.

[0057] It should be noted that in Figures 1 to 4 , Figure 6 In the illustrated embodiments, the component indicated by the reference numeral "110" shown in the drawings is actually only a portion of the main channel portion 110. The heat exchange components in these embodiments can be applied, for example, to Figure 7 For example, in an immersed battery device, the main channel portion 110 may be a cavity structure enclosed by a portion of the battery 300 housing 200 and a channel plate. The channel plate may be understood as Figures 1 to 4 , Figure 6 Furthermore, in Figure 5 In the embodiment shown in the figure, the component indicated by the number "110" is actually the main channel portion 110 itself. The heat exchange component in this embodiment can be applied to, for example, Figure 8 For example, in a battery device with contact heat exchange, the main channel portion 110 may be a first heat exchange plate 116, which may be understood as Figure 5 The component marked as "110" in.

[0058] like Figures 1 to 3 As shown, in one embodiment of the present invention, the heat exchange component proposed by the present invention may include at least one main channel portion 110 and at least two diverter portions 120, and at least one main channel portion 110 is spliced ​​and connected with at least two diverter portions 120. Through the above structural design, the present invention can use at least two diverter portions 120 to achieve the distribution of heat exchange medium to at least two different positions.

[0059] like Figure 3 As shown, in one embodiment of the present invention, the heat exchange component provided by the present invention may include at least two first flow diversion parts 1201 arranged along the first direction X, and the opening areas of the at least two first flow diversion parts 1201 are not equal. Through the above structural design, the present invention can use at least two first flow diversion parts 1201 to divert the heat exchange medium to at least two different positions, thereby realizing the diversion control of at least two different positions.

[0060] like Figure 3As shown, based on the structural design that the heat exchange component includes at least two first diverter parts 1201, in one embodiment of the utility model, the areas of the diverter holes 121 of at least two first diverter parts 1201 may not be equal. The so-called area of ​​the diverter hole 121 can be understood as the sum of the areas of the orthographic projection figures of all the diverter holes 121 on one first diverter part 1201 on the first surface 114. On this basis, for two first diverter parts 1201 with unequal opening areas (i.e., the areas of the diverter holes 121), the number of openings (i.e., the number of diverter holes 121) of the two may be equal or unequal, and the area of ​​a single diverter hole 121 of the two may be equal or unequal. Through the above structural design, the utility model can achieve different diversion rates by using the first diverter parts 1201 corresponding to different positions.

[0061] like Figure 3 As shown, based on the structural design that the heat exchange component includes at least two first flow dividers 1201, in one embodiment of the utility model, the heat exchange component is connected to a medium inlet 130, and the medium inlet 130 is suitable for allowing the heat exchange medium to enter the first chamber 111. Figure 3 The medium inlet 130 is not shown in the figure, and can be used according to Figure 7 The medium inlet 130 of the submerged battery device shown is understood in conjunction with this. Figure 3 The relative position of the medium inlet 130 is understood as being located on the left side of the heat exchange component along the first direction X. On this basis, along the first direction X, for any two first shunt parts 1201, the opening area of ​​the one closer to the medium inlet 130 can be greater than or equal to the opening area of ​​the other. Through the above structural design, the utility model increases the shunt rate of the area relatively close to the medium inlet 130. Taking a battery pack composed of multiple batteries arranged along the first direction X as an example, for any two batteries 300 in the battery pack, the utility model can make the heat exchange efficiency of one relatively close to the medium inlet 130 higher than or at least not lower than the heat exchange efficiency of the other, which is conducive to ensuring the balance of the overall heat exchange effect of the battery pack.

[0062] like Figure 3As shown, based on the structural design that the opening area of ​​the first diverter 1201 close to the medium inlet 130 is greater than or equal to the opening area of ​​the first diverter 1201 far from the medium inlet 130, in one embodiment of the utility model, the area of ​​each diverter hole 121 can be equal, that is, the area of ​​all diverter holes 121 set by each first diverter 1201 itself is equal, and the area of ​​the single diverter hole 121 set by all first diverters 1201 is equal. On this basis, along the first direction X, for any two first diverters 1201, the number of openings of one close to the medium inlet 130 is greater than or equal to the number of openings of the other. Through the above structural design, the utility model designs the area of ​​all diverter holes 121 to be equal, which can facilitate the processing and manufacturing of the first diverter 1201, and by using the difference design of the number, the difference design of the opening area of ​​each first diverter 1201 can be achieved. On this basis, the shapes of all diverter holes 121 can also be the same. In some embodiments, the number of diversion holes 121 provided in each first diversion portion 1201 may also be equal. On this basis, along the first direction X, for any two first diversion portions 1201, the area of ​​the diversion hole 121 of one closer to the medium inlet 130 may be greater than or equal to the area of ​​the diversion hole 121 of the other, and is not limited to this embodiment.

[0063] like Figures 1 to 3 As shown, based on the structural design that the opening area of ​​the first diverter 1201 close to the medium inlet 130 is greater than or equal to the opening area of ​​the first diverter 1201 far from the medium inlet 130, in one embodiment of the utility model, the diverter 120 may also include a second diverter 1202, which does not have a structure connected to the first chamber 111. For example, the second diverter 1202 can be understood as a component that does not have a diverter hole 121 and has the same other structural forms as the first diverter 1201. On this basis, along the first direction X, any second diverter 1202 is arranged farther away from the medium inlet 130 than any first diverter 1201. Through the above structural design, the utility model can realize the interception of the heat exchange medium in a partial area, blocking the heat exchange medium from directly entering the partial area, and of course does not limit the heat exchange medium from flowing to other areas after being diverted to the partial area via the first diverter 1201. Based on this, the utility model can be further adapted to the differentiated heat exchange characteristics of the battery pack in different areas, which is beneficial to ensure the balance of the overall heat exchange effect of the battery pack.

[0064] In one embodiment of the utility model, the main channel portion 110 has a first surface 114 facing away from the first chamber 111. The plane where the first surface 114 is located is used as a reference plane. On this reference plane, for any first diversion portion 1201, the sum of the areas of the orthographic projections of all the diversion holes 121 may account for 1.74% to 10.44% of the total area of ​​the orthographic projection of the first diversion portion 1201, for example, 1.74%, 2%, 5%, 10%, 10.44%, etc. The so-called total area of ​​the orthographic projection of the first diversion portion 1201 refers to the area of ​​the figure enclosed by the outline of the orthographic projection of the first diversion portion 1201, that is, the area of ​​the orthographic projections of all the diversion holes 121 set in the first diversion portion 1201. Through the above structural design, the utility model can avoid the opening area of ​​the first diverter 1201 being too small to provide a sufficient diverter rate, and can also avoid the opening area of ​​the first diverter 1201 being too large to make the diverter rate too high or affect the structural strength of the first diverter 1201. In some embodiments, the sum of the above areas may account for less than 1.74% of the above total area, or may be greater than 10.44%, such as 1.73%, 10.45%, and is not limited to this embodiment.

[0065] See also Figure 6 , Figure 6 , a three-dimensional exploded schematic diagram of a partial structure of a heat exchange component in another exemplary embodiment that can embody the principle of the present utility model is representatively shown, in which specifically one assembling part 115 is separated from other assembling parts 115 .

[0066] Different from Figures 1 to 3 , Figure 5 In the embodiment shown, the main channel portion 110 (or the above-mentioned channel plate) is used as a structural design of an integral component, such as Figure 6 As shown, in one embodiment of the present invention, the main channel portion 110 includes at least two assembling portions 115, at least two assembling portions 115 are relatively independent split components and are spliced ​​and connected in sequence, and the main channel portion 110 is assembled and connected with the assembling portion 115 and the diverter portion 120, for example, the assembling portion 115 can be provided with the above-mentioned assembly groove 112. On this basis, each assembling portion 115 is provided with a diverter portion 120. Through the above-mentioned structural design, the present invention can use the assembling portion 115 to realize the modular and unitized design of the main channel portion 110, which can be suitable for flexible assembly of a variety of different application scenarios, and improve the flexibility of replacement and disassembly of the parts of the heat exchange component.

[0067] like Figure 6As shown, based on the structural design that the main channel portion 110 includes at least two assembling portions 115, in one embodiment of the present invention, the number of diverter portions 120 provided in each assembling portion 115 can be equal. Through the above structural design, the present invention can further optimize the modular and unitized design of the main channel portion 110. In some embodiments, when the main channel portion 110 includes at least two assembling portions 115, the number of diverter portions 120 provided in different assembling portions 115 may also be unequal, and is not limited to this embodiment.

[0068] like Figure 6 As shown, based on the structural design that the number of diverter portions 120 provided on each assembly portion 115 is equal, in one embodiment of the utility model, each assembly portion 115 is provided with at least two diverter portions 120. For example, each assembly portion 115 shown in the drawings is provided with four diverter portions 120. On this basis, the structures of the diverter portions 120 provided on the same assembly portion 115 are completely the same. For example, in Figure 6 In the order from left to right along the first direction X, the five assembling parts 115 on the left are all provided with the first diverter part 1201, and for any one of the five assembling parts 115, the structures of the first diverter parts 1201 provided therein are completely the same, that is, the number, position, shape and size of the diverter holes 121 are all the same. In addition, the diverter parts 120 provided in the rightmost assembling part 115 are all second diverter parts 1202. On this basis, the numbers of the diverter holes 121 of the diverter parts 120 provided in different assembling parts 115 are not equal. For example, for the five assembling parts 115 on the left, one of any two relatively close to the medium inlet 130 is provided with more openings of the first isolating part than the other. Through the above structural design, the utility model can further realize modular and unitized design for each assembly part 115. For any assembly part 115, the diversion parts 120 configured therein are all components with the same structure, which has high flexibility in replacement and disassembly and is conducive to mass production.

[0069] like Figure 6 As shown, based on the structural design that the main channel portion 110 includes at least two assembling portions 115, in one embodiment of the utility model, two adjacent assembling portions 115 can be engaged with each other via an engaging structure 1151. The engaging structure 1151 can, for example, include an engaging protrusion and a slot. Further, the engaging protrusion and the slot can be dovetail-shaped with matching shapes.
