Detailed Implementation
[0058] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0059] With the rapid development of electric vehicles, on-board battery packs have become an important component of automobiles. During charging and discharging, battery packs generate a significant amount of heat; therefore, heat dissipation is necessary to maintain the battery pack's temperature within a reasonable range.
[0060] In existing technologies, a heat exchange assembly is typically installed at the top of the battery pack to achieve heat dissipation. This heat exchange assembly includes a heat spreader, a flow channel plate, an annular support, and a sealing plate connected in sequence. The heat spreader is connected to the upper surface of the battery pack, the flow channel plate is fitted to the heat spreader, the annular support is sandwiched between the edge of the heat spreader and the edge of the sealing plate, and the side of the sealing plate facing away from the support is connected to the first side of the sealing foam, while the second side of the sealing foam is connected to the vehicle body, thus achieving a sealed connection between the battery pack and the vehicle body.
[0061] This heat exchange component not only achieves heat dissipation for the battery pack but also ensures a sealed connection between the battery pack and the vehicle body, preventing compression of the flow channels on the flow plates. However, the heat exchange component comprises many parts, resulting in a complex structure. Consequently, its manufacturing process is more complex and consumes more raw materials, leading to higher production costs for the heat exchange component and, consequently, higher production costs for the battery pack.
[0062] Based on the aforementioned technical problems, the flow channel plate provided in this application has a flow channel and a mating portion. The mating portion is used to accommodate a sealing element, which is used to achieve a seal between the flow channel plate and the vehicle body. The mating portion does not have a flow channel, allowing the first contact portion of the sealing element to connect with the mating portion without compressing the flow channel, and the second contact portion of the sealing element to achieve a sealing connection with the vehicle body. When this flow channel plate is installed in a heat exchange structure, it can replace the combination of flow channel plates, annular support members, and sealing plates in existing heat exchange components. Compared to existing heat exchange components, this heat exchange structure includes fewer components, has a simpler structure, and consequently lower production costs, thus reducing the production cost of the battery pack.
[0063] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.
[0064] The following provides a detailed description of the specific structure of the aforementioned flow channel plate and various possible implementation methods.
[0065] Figure 1 This is a schematic diagram of the structure of a flow channel plate 111 provided in an embodiment of this application. Figure 2 for Figure 1 A partial structural diagram of the central flow channel plate 111. Figure 3 This is a schematic diagram of the structure of a heat exchange structure 110 and a sealing element 200 provided in an embodiment of this application. Figure 4 for Figure 3 Schematic diagram of the structure of the temperature distribution plate 112. Figure 10 for Figure 1 A structural diagram showing the connection between the flow channel plate and the vehicle body. Figure 11 for Figure 1 A schematic diagram of the structure when the flow channel plate is separated from the main body of the vehicle.
[0066] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 The flow channel plate 111 has a flow channel 1111 and a mating part 1112 is formed on the flow channel plate 111. The mating part 1112 is used to accommodate the seal 200, and the seal 200 is used to achieve a seal between the flow channel plate 111 and the vehicle body 300.
[0067] In this embodiment, the mating part 1112 does not have a flow channel 1111. The first contact part of the seal 200 can connect with the mating part 1112 without compressing the flow channel 1111, and the second contact part of the seal 200 can be sealed to the vehicle body 300. When the flow channel plate 111 is installed on the heat exchange structure 110, it can replace the combination of flow channel plates, annular support members, and sealing plates in the heat exchange assembly of the prior art. Compared with the heat exchange assembly of the prior art, the heat exchange structure 110 includes fewer components and has a simpler structure, thus reducing the production cost of the heat exchange structure 110 and reducing the production cost of the battery pack 100.
[0068] It should be noted that the flow channel 1111 is filled with a liquid heat-conducting medium. When the heat-conducting medium flows through the flow channel 1111, it can dissipate the heat it carries to the outside air through the wall of the flow channel 1111, thereby achieving the effect of heat dissipation.
[0069] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 The flow channel plate 111 includes a plate body 1115, and a mating part 1112 is located on at least one side of the plate body 1115 along the thickness direction.
[0070] When the first contact portion of the seal 200 is connected to the mating portion 1112, the mating portion 1112 can apply a supporting force to the seal 200. When the second contact portion of the seal 200 is sealed to the vehicle body 300, the supporting force can compress the seal 200, thereby making the second contact portion of the seal 200 more firmly connected to the vehicle body 300, thus improving the sealing effect of the seal 200.
[0071] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The flow channel 1111 is provided on at least one side of the plate surface of the plate body 1115 along the thickness direction.
[0072] In this way, the flow channel plate 111 can provide sufficient area to set the flow channels 1111, which is conducive to the heat dissipation of the flow channels 1111, thus improving the heat dissipation effect of the flow channel plate 111. In addition, the plate surface of the flow channel plate 111 without the flow channels 1111 can be connected to the heat spreader 112.
[0073] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The plate 1115 has a first plate surface and a second plate surface that are arranged opposite to each other along the thickness direction; the flow channel 1111 and the mating part 1112 are both located on the first plate surface.
[0074] In this way, the flow channel 1111 and the mating part 1112 are both located on the same plate surface of the plate body 1115, which facilitates the spatial arrangement of the flow channel plate 111. Specifically, the second plate surface of the flow channel plate 111 can be directly connected to the cell module 120, and the first plate surface of the flow channel plate 111 can be separated from the cell module 120, which facilitates the installation of the flow channel plate 111.
[0075] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11 The mating part 1112 is a clearance part, which is located on the surface of the flow channel plate 111 at a position offset from the flow channel 1111.
[0076] This facilitates the connection between the clearance portion and the seal 200. Specifically, the first contact portion of the seal 200 can directly connect with the clearance portion without squeezing the flow channel 1111, thereby ensuring a more stable operation of the flow channel plate 111 while maintaining a sealed connection between the flow channel plate 111 and the vehicle body 300.
[0077] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 The mating part 1112 includes a clearance groove 11121; the clearance groove 11121 is formed on at least one side of the flow channel plate 111 along the thickness direction.
[0078] When the first contact portion of the seal 200 is connected to the bottom of the clearance groove 11121, the bottom of the clearance groove 11121 can apply a supporting force to the seal 200. When the second contact portion of the seal 200 is sealed to the vehicle body 300, this supporting force can compress the seal 200, thereby making the second contact portion of the seal 200 more firmly connected to the vehicle body 300, thus improving the sealing effect of the seal 200.
[0079] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11 The clearance groove 11121 is located on the first surface of the plate 1115.
[0080] Thus, the clearance groove 11121 and the flow channel 1111 are located on the same surface of the plate 1115, which further facilitates the spatial arrangement of the flow channel plate 111. Specifically, when the flow channel plate 111 is installed on the battery pack 100, the flow channel 1111 is set on the first surface of the flow channel plate 111, and the first surface can be connected to the vehicle body 300.
[0081] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11 The bottom of the clearance groove 11121 is located on the surface of the flow channel plate 111 at a position offset from the flow channel 1111, and the bottom of the clearance groove 11121 is a plane.
[0082] This facilitates the connection between the bottom of the clearance groove 11121 and the seal 200. Specifically, the first contact portion of the seal 200 can directly connect with the bottom of the clearance groove 11121 without squeezing the flow channel 1111. This ensures a sealed connection between the flow channel plate 111 and the vehicle body 300, and also makes the flow channel plate 111 operate more stably.
[0083] Furthermore, since the bottom of the clearance groove 11121 is flat, when the first contact portion of the seal 200 is connected to the bottom of the connecting groove and the second contact portion of the seal 200 is connected to the vehicle body 300, the deformation of the seal 200 at various positions is more uniform, thereby making the connection between the flow channel plate 111 and the vehicle body more stable. Since the battery pack 100 is generally rectangular, when the plate 1115 is a flat plate 1115, it is convenient for the flow channel plate 111 to be connected to the battery pack 100.
[0084] It should be noted that the aforementioned clearance groove 11121 is formed by the plate body 1115 of the flow channel plate 111 and the flow channel 1111 walls of the two flow channels 1111, that is, the side wall of the clearance groove 11121 is the flow channel 1111 wall of the flow channel 1111.
[0085] It should also be noted that the aforementioned plate 1115 is a flat plate. This facilitates the connection between the battery pack 100 and the vehicle body 300, thereby reducing the space occupied by the battery pack 100.
[0086] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 The mating part 1112 includes a clearance hole, which penetrates through the flow channel plate 111 along the thickness direction of the flow channel plate 111.
[0087] At this time, the seal 200 is connected to the wall of the clearance hole, and the second contact part of the seal 200 is sealed to the body body 300, so that the flow channel plate 111 and the body body 300 can be sealed to each other.
[0088] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11 The clearance hole is located on the surface of the flow channel plate 111 at a position offset from the flow channel 1111.
[0089] This facilitates the connection between the wall of the clearance hole and the seal 200. Specifically, the first contact portion of the seal 200 can directly connect with the wall of the clearance hole without compressing the flow channel 1111. This ensures a sealed connection between the flow channel plate 111 and the vehicle body 300, and also makes the flow channel plate 111 operate more stably.
[0090] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The dimensions of the clearance hole along the surface of the flow channel plate 111 are the same as the dimensions of the seal 200 along the surface of the flow channel plate 111. This facilitates the integral insertion of the seal 200 into the clearance hole and its connection with the hole wall.
[0091] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 There are multiple flow channels 1111, including a first flow channel 1113 and a second flow channel 1114. Along the plate surface direction of the flow channel plate 111, the first flow channel 1113 and the second flow channel 1114 are located on opposite sides of the mating part 1112.
[0092] That is, the first flow channel 1113 and the second flow channel 1114, which are located on the same straight extension line, can be regarded as being formed by being cut off by the mating part 1112. This ensures that the flow channel 1111 is not provided at the position of the mating part 1112, so that the first contact part of the seal 200 can connect with the mating part 1112 without squeezing the flow channel 1111. This ensures the sealing connection effect of the seal 200 while ensuring that the flow channel 1111 is not damaged, thus making the flow channel plate 111 operate more stably.
[0093] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The flow channel plate 111 is used to connect with the heat spreader 112; the first flow channel 1113 and the second flow channel 1114 are both used to communicate with the auxiliary flow channel 113 of the heat spreader 112.
[0094] In this embodiment, the flow channel plate 111 is used to connect with the heat spreader plate 112. When the flow channel plate 111 and the heat spreader plate 112 are connected, the heat spreader plate 112 can disperse and evenly transfer the heat generated by the battery module 120 to the flow channel plate 111. This makes the heating of various parts of the flow channel plate 111 more uniform, thus improving the heat dissipation effect of the flow channel plate 111. Since both the first flow channel 1113 and the second flow channel 1114 are used to communicate with the auxiliary flow channel 113 of the heat spreader plate 112, the first flow channel 1113 and the second flow channel 1114, which are cut off by the mating part 1112, are connected again through the auxiliary flow channel 113 of the heat spreader plate 112. This reduces the impact of the mating part 1112 on the length of the flow channel 1111, thereby improving the heat dissipation effect of the flow channel plate 111.
[0095] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11 The first flow channel 1113 is located in the middle region of the flow channel plate 111, and the second flow channel 1114 and the mating part 1112 are both located on the side of the first flow channel 1113 near the edge of the flow channel plate 111.
[0096] Since the first flow channel 1113 is located in the central region of the flow channel plate 111, the first flow channel 1113 in the central region of the flow channel plate 111 is complete, thus ensuring the heat dissipation effect of the flow channel plate 111. Since both the second flow channel 1114 and the mating part 1112 are located on the side of the first flow channel 1113 near the edge of the flow channel plate 111, when the mating part 1112 is connected to the seal 200, the seal 200 is also located on the side of the first flow channel 1113 near the edge of the flow channel plate 111, thus making the connection between the flow channel plate 111 and the vehicle body 300 more secure.
[0097] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11 The mating part 1112 includes a first connecting part 11122, which is used to connect with the heat spreader 112.
[0098] Some of the seals 200 can be connected to the first connecting part 11122, which increases the connection area between the flow channel plate 111 and the vehicle body 300, thus making the connection between the flow channel plate 111 and the vehicle body 300 more secure. Since the first connecting part 11122 is used to connect with the heat exchange plate 112, it is convenient to install the flow channel plate 111 in the heat exchange structure 110.
[0099] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The first connecting part 11122 is an annular connecting part located at the edge of the flow channel plate 111, and the flow channel 1111 is located in the area enclosed by the annular connecting part.
[0100] In this way, the first connecting part 11122 will not occupy the middle area of the flow channel plate 111, and the flow channel 1111 can be set in the middle area of the flow channel plate 111, avoiding the first connecting part 11122 from cutting off the flow channel 1111, thus facilitating the layout of the flow channel 1111.
[0101] Since the first connecting part 11122 is an annular connecting part, the flow channel 1111 is located within the area enclosed by the annular connecting part. In this way, the edge of the flow channel plate 111 can be connected to the heat exchange plate 112 around its perimeter, thereby enhancing the stability of the heat exchange structure 110.
[0102] The first connecting portion 11122 is provided with a plurality of first connecting holes 111221, which are spaced apart along the extending direction of the first connecting portion 11122.
[0103] The connector of the heat exchange structure 110 can pass through the first connection hole 111221 and connect to the tray of the battery pack 100, thereby enhancing the stability of the heat exchange structure 110.
[0104] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11 The mating part 1112 includes a clearance groove 11121, which extends to the position of the first connecting part 11122.
[0105] In this way, when setting the seal 200, the seal 200 connected to the clearance groove 11121 and the seal 200 connected to the first connecting part 11122 can be connected as a whole. That is, the seal 200 can extend continuously from the connecting groove to the first connecting part 11122, thereby increasing the total length of the seal 200, and thus making the flow channel plate 111 more firmly connected to the vehicle body 300.
[0106] This application embodiment also provides a heat exchange structure 110, see [link]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11 The heat exchange structure 110 includes any of the above-mentioned flow channel plate 111 and heat spreader plate 112. The heat spreader plate 112 is connected to the flow channel plate 111.
[0107] Since the flow channel plate 111 does not have a flow channel 1111 at the mating part 1112, the first contact part of the seal 200 can connect with the mating part 1112 without compressing the flow channel 1111, and the second contact part of the seal 200 can be sealed to the vehicle body 300. When the flow channel plate 111 is installed on the heat exchange structure 110, it can replace the combination of flow channel plates, annular support members, and sealing plates in the heat exchange assembly of the prior art. Compared with the heat exchange assembly of the prior art, the heat exchange structure 110 includes fewer parts and has a simpler structure, thus reducing the production cost of the heat exchange structure 110 and reducing the production cost of the battery pack 100.
[0108] Because the heat spreader 112 is connected to the flow channel plate 111, the heat spreader 112 can distribute and evenly transfer the heat generated by the battery module 120 to the flow channel plate 111. This makes the heat distribution of each part of the flow channel plate 111 more uniform, thus improving the heat dissipation effect of the flow channel plate 111.
[0109] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The temperature distribution plate 112 is provided with an auxiliary flow channel 113, and the two ends of the auxiliary flow channel 113 are connected to the flow channel 1111 on the flow channel plate 111.
[0110] Specifically, the auxiliary flow channel 113 connects the first flow channel 1113 and the second flow channel 1114 formed by the cutting of the flow channel plate 111 by the mating part 1112, thereby reducing the influence of the mating part 1112 on the length of the flow channel 1111 and thus improving the heat dissipation effect of the flow channel plate 111.
[0111] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11 The first end of the auxiliary flow channel 113 is connected to the first flow channel 1113 of the flow channel plate 111; the second end of the auxiliary flow channel 113 is connected to the second flow channel 1114 of the flow channel plate 111.
[0112] In this embodiment, when the heat spreader 112 is connected to the flow channel plate 111, the first end and the second end of the auxiliary flow channel 113 are respectively connected to the first flow channel 1113 and the second flow channel 1114. Specifically, the ends of the first flow channel 1113 and the second flow channel 1114 located on opposite sides of the mating part 1112 are also located on opposite sides of the mating part 1112. This connects the first flow channel 1113 and the second flow channel 1114 located on opposite sides of the mating part 1112, thus reducing the influence of the mating part 1112 on the length of the flow channel 1111 and improving the heat dissipation effect of the flow channel plate 111.
[0113] Furthermore, by providing an auxiliary flow channel 113 to the heat exchange plate 112, the structural strength of the edge of the heat exchange structure 110 can be enhanced when the heat exchange plate 112 is connected to the flow channel plate 111. Thus, when the seal 200 is connected to the first connecting part 11122, the seal 200 has a good compressibility, thereby achieving a sealed connection between the flow channel plate 111 and the vehicle body 300, and thus achieving a sealed connection between the battery pack 100 and the vehicle body 300.
[0114] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The temperature distribution plate 112 includes a first surface and a second surface that are disposed opposite to each other along the thickness direction. The first surface of the temperature distribution plate 112 is connected to the second surface of the flow channel plate 111.
[0115] Since the first plate surface of the flow channel plate 111 is provided with flow channels 1111, and the heat equalization plate 112 is connected to the second plate surface of the flow channel plate 111, it can be ensured that the heat equalization plate 112 will not squeeze the flow channels 1111 on the first plate surface of the flow channel plate 111, thereby ensuring the normal operation of the flow channel plate 111.
[0116] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The auxiliary flow channel 113 is disposed on the second surface of the heat spreader 112.
[0117] Since the first surface of the heat exchange plate 112 is connected to the second surface of the flow channel plate 111, the auxiliary flow channel 113 will not affect the connection between the heat exchange plate 112 and the flow channel plate 111, thus facilitating the spatial arrangement of the heat exchange structure 110.
[0118] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The auxiliary flow channel 113 is located at the edge of the second surface of the heat spreader 112.
[0119] When the heat spreader 112 is connected to the cell module 120, the auxiliary flow channel 113 is located in the gap 140 between the battery frame 130 and the cell module 120. As a result, the auxiliary flow channel 113 will not occupy the effective space of the battery pack 100, which is beneficial to the overall spatial arrangement of the battery pack 100.
[0120] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9 The axis of the auxiliary flow channel 113 is parallel to the edge of the heat spreader 112 closest to it.
[0121] In this way, when the second surface of the heat spreader 112 is connected to the cell module 120 of the battery pack 100, it is easier to set the auxiliary flow channel 113 in the gap 140 between the battery frame 130 and the cell module 120, thereby reducing the probability of the auxiliary flow channel 113 colliding with the battery frame 130 and thus improving the assembly efficiency of the battery pack 100.
[0122] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The auxiliary flow channel 113 includes a flow groove 1131, and the heat spreader 112 is provided with a connecting hole 1121, which penetrates the heat spreader 112. The side of the flow groove 1131 with an opening is detachably connected to the second surface of the heat spreader 112 so that the flow groove 1131 communicates with the connecting hole 1121.
[0123] Compared to the design of integrating the flow channel 1131 and the heat spreader 112, this design allows for the detachable connection of the open side of the flow channel 1131 to the second surface of the heat spreader 112. This enables the heat spreader 112 and the flow channel 1131 to be produced separately and then connected together, thereby reducing the cost of developing large-size stamping dies and further reducing the production cost of the heat exchange structure 110.
[0124] It should be noted that the above-mentioned flow channel 1131 and the second surface of the heat spreader 112 can be detachably connected by welding, bonding, or other connection methods, and this application embodiment does not limit this. In addition, the auxiliary flow channel 113 on the heat spreader 112 can also be formed in one step by stamping the heat spreader 112.
[0125] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The size of the connecting hole 1121 is the same as the size of the opening of the flow channel 1131.
[0126] In this way, the size of the opening of the flow channel 1131 can be matched with the size of the connecting hole 1121, thus avoiding waste of material in the flow channel 1131. In addition, the opening of the flow channel 1131 can be smoothly connected to the wall of the connecting hole 1121, which allows the heat transfer medium to flow more smoothly in the flow channel 1131, thereby improving the heat dissipation effect of the flow channel plate 111.
[0127] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The second connecting part 1122 is located at the edge of the heat exchange plate 112.
[0128] Since the first connecting part 11122 of the flow channel plate 111 is located at the edge of the first flow channel 1113 plate 111, the second connecting part 1122 is disposed at the edge of the heat equalization plate 112 to facilitate the connection of the first connecting part 11122 and the second connecting part 1122.
[0129] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The second connecting part 1122 is provided with a second connecting hole 11221, and the heat exchange structure 110 includes a connector, which passes through the first connecting hole 11221 and the second connecting hole 11221.
[0130] In this embodiment, by simultaneously passing the connector through the first connection hole 111221 and the second connection hole 11221 to achieve the tray connection between the heat exchange structure 110 and the battery pack 100, the heat exchange structure 110 can be more stably assembled into the battery pack 100.
[0131] It should be noted that the aforementioned connectors may be bolts or rivets, or other connectors with the same function; this application does not limit this.
[0132] This application also provides a battery pack 100, see [link to previous document]. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The battery pack 100 includes a battery pack body and any of the above-mentioned heat exchange structures 110 or any of the above-mentioned flow channel plates 111, with the flow channel plate 111 disposed on the battery pack body.
[0133] Since the flow channel plate 111 does not have a flow channel 1111 at the mating part 1112, the first contact part of the seal 200 can connect with the mating part 1112 without squeezing the flow channel 1111, and the second contact part of the seal 200 can be sealed to the vehicle body 300. When the flow channel plate 111 is installed on the heat exchange structure 110, it can replace the combination of flow channel plates, annular support members, and sealing plates in the heat exchange assembly of the prior art. Compared with the heat exchange assembly of the prior art, the heat exchange structure 110 includes fewer parts and has a simpler structure, thus reducing the production cost of the heat exchange structure 110 and thereby reducing the production cost of the battery pack 100.
[0134] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 9 The battery pack body includes a cell module 120. When the battery pack 100 includes a heat exchange structure 110, the second surface of the heat exchange structure 110's heat spreader 112 is connected to the cell module 120.
[0135] Since the heat spreader 112 is connected to the flow channel plate 111, the heat spreader 112 can distribute and evenly transfer the heat generated by the cell module 120 to the flow channel plate 111. This makes the heat distribution of each part of the flow channel plate 111 more uniform, thus improving the heat dissipation effect of the flow channel plate 111 and thereby improving the heat dissipation effect of the battery pack 100.
[0136] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 9 The battery pack body includes a battery frame 130 with an opening, a cell module 120 located inside the battery frame 130, and a heat spreader 112 located on the side of the battery frame 130 with the opening; there is a gap 140 between the cell module 120 and the side wall of the battery frame 130, and the auxiliary flow channel 113 of the heat spreader 112 is located inside the gap 140.
[0137] In this embodiment, since the cell module 120 is located inside the battery frame 130, the battery frame 130 can protect the cell module 120, thereby making the battery pack 100 operate more stably. Because the heat spreader 112 is located on the side of the battery frame 130 with an opening, and the second surface of the heat spreader 112 is also connected to the cell module 120, the heat dissipation function of the battery pack 100 can be guaranteed.
[0138] Because there is a gap 140 between the cell module 120 and the side wall of the battery frame 130, the auxiliary flow channel 113 of the heat spreader 112 is located within the gap 140. Thus, when the heat spreader 112 is connected to the cell module 120, the auxiliary flow channel 113 is precisely located within the gap 140 between the battery frame 130 and the cell module 120. Consequently, the auxiliary flow channel 113 does not occupy the effective space of the battery pack 100, which is beneficial for the overall spatial arrangement of the battery pack 100 and thus helps to reduce the volume of the battery pack 100.
[0139] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 9 The gap 140 is filled with an insulating medium. In this way, the cell module 120 and the side wall of the battery frame 130 are isolated by the insulating medium, thereby preventing the battery frame 130 from becoming charged and thus improving the safety of the battery pack 100.
[0140] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 9 The battery frame 130 is provided with a cavity 131.
[0141] The existing battery pack 100 typically has a gap 140 for placing brackets or wiring harnesses, etc. This application utilizes this gap 140 to provide space for the auxiliary flow channel 113, thereby improving the space utilization of the battery pack 100.
[0142] The number of cavities 131 can be multiple, and multiple cavities 131 are spaced apart in the battery frame 130.
[0143] This application also provides a vehicle, see [link to example]. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The vehicle includes a body body 300 and any of the aforementioned battery packs 100. The flow channel plate 111 of the battery pack 100 is connected to the body body 300.
[0144] Since the battery pack 100 includes any of the aforementioned heat exchange structures 110, and the heat exchange structure 110 includes any of the aforementioned flow channel plates 111, the flow channel plate 111 does not have a flow channel 1111 at the mating part 1112. The first contact part of the seal 200 can connect with the mating part 1112 without compressing the flow channel 1111, and the second contact part of the seal 200 can be sealed to the vehicle body 300. When the flow channel plate 111 is installed on the heat exchange structure 110, it can replace the combination of flow channel plates, annular support members, and sealing plates in the heat exchange assembly of the prior art. Compared with the heat exchange assembly of the prior art, the heat exchange structure 110 includes fewer components and has a simpler structure, resulting in lower production costs. Therefore, the production cost of the battery pack 100 can be reduced, which in turn reduces the production cost of the vehicle.
[0145] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The vehicle includes a seal 200, which has a first contact portion and a second contact portion; the first contact portion of the seal 200 is connected to the mating portion 1112 of the flow channel plate 111, and the second contact portion of the seal 200 is connected to the vehicle body 300.
[0146] In this way, the flow channel plate 111 and the body body 300 can be sealed and connected by the seal 200, thereby achieving a sealed connection between the battery pack 100 and the body body 300.
[0147] It should be noted that the aforementioned sealing element 200 can be sealing foam, rubber, or silicone, or it can be a sealing element 200 made of other materials. This application embodiment does not limit this.
[0148] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11 When the mating part 1112 includes a relief groove 11121, the first contact portion of the seal 200 is connected to the inner wall of the relief groove 11121. Or when the mating part 1112 includes a relief hole, the first contact portion of the seal 200 is connected to the hole wall of the relief hole.
[0149] Both the aforementioned clearance groove 11121 and clearance hole can connect to the seal 200. However, the bottom of the clearance groove 11121 can exert a squeezing effect on the seal 200, which is beneficial to the connection between the flow channel plate 111 and the body body 300. Therefore, the solution of setting clearance groove 11121 is generally adopted.
[0150] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 10 and Figure 11 The first contact portion of the seal 200 is connected to the first connection portion 11122.
[0151] Thus, the first connecting portion 11122 of the flow channel plate 111 can be used not only to connect the heat exchange plate 112, but also to connect the first contact portion of the seal 200. Furthermore, the seal 200 can extend continuously from the relief groove 11121 to the first connecting portion 11122, increasing the total length of the seal 200 and thus increasing the connection area between the flow channel plate 111 and the seal 200, thereby making the sealing connection between the flow channel plate 111 and the vehicle body 300 more reliable.
[0152] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 10 and Figure 11 The sealing element 200 is a sealing foam element.
[0153] Since the sealing foam is an elastic and flexible material, when the sealing foam is connected to both the body body 300 and the runner plate 111, it will undergo elastic deformation due to compression, thus achieving a better sealing effect.
[0154] It should be noted that the aforementioned sealing element 200 can be a sealing foam element, a rubber element, a silicone element, or a sealing element 200 made of other materials. This application embodiment does not limit this.
[0155] It should be noted that the aforementioned vehicles may be sedans, SUVs, trucks, or buses, or other types of vehicles; this application embodiment does not limit this.

Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.
[0157] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "one" or "" can also be understood to convey either singular or plural usage.
[0158] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something,” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “above something” or “on top of something,” but also “on something” or “on top of something” without an intermediate feature or layer therebetween, i.e., directly on something.
[0159] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures.

The device may have other orientations rotated 90° or be in other orientations, and the spatially relative descriptive terms used herein may be interpreted accordingly.
[0160] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
