Description

Technical Field

[0001] This application relates to the field of power battery technology, and in particular to a heat exchange component, a battery pack, and a vehicle. Background Technology

[0002] The battery pack in an electric vehicle generates heat during operation, causing its temperature to rise. The longer the battery pack operates, the more heat accumulates, and the higher the temperature becomes. If the battery pack is not cooled down in a timely manner, its performance and lifespan will be affected.

[0003] In existing technologies, battery packs typically include a frame, cell modules housed within the frame, and a cold plate. The cell modules are mounted on the cold plate, which has internal flow channels. Cooling medium flows through these channels to cool the individual cells within the cell modules. Since the cooling medium enters the cold plate's flow channels from outside the battery pack, clearance holes need to be created in the frame to direct the cold plate's inlet outside the frame to receive the cooling medium.

[0004] However, in the above structure, the sealing performance between the frame and the cold plate is difficult to guarantee, which will affect the cooling effect of the cold plate. Utility Model Content

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0051] The terms “first,” “second,” “third,” and “fourth,” etc. (if present), in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0052] As described in the background section, a battery pack typically includes a frame, battery cell modules housed within the frame, and a cold plate. The battery cell modules are mounted on the cold plate, which has internal flow channels. Cooling medium flows through these channels to cool the individual cells within the battery cell modules. Since the cooling medium enters the flow channels of the cold plate from outside the battery pack, clearance holes need to be provided in the frame to direct the cold plate's inlet outside the frame to receive the cooling medium.

[0053] However, by leading the cold plate's inlet and outlet out of the frame through clearance holes, it is difficult to guarantee the sealing performance between the frame and the cold plate, which will affect the cooling effect of the cold plate.

[0054] To address the aforementioned problems in the prior art, this utility model provides a heat exchange component, a battery pack, and a vehicle. The heat exchange component includes a frame, a mounting base, a cold plate, a bottom guard plate, and a seal. The mounting base is disposed on one side of the frame, the cold plate is disposed within the frame, and the bottom guard plate has a receiving portion on one side. The bottom guard plate is disposed on the frame and covers the cold plate, and the mounting base is connected to the receiving portion. The cold plate has an inlet channel and an outlet channel, both of which are connected to an external cooling system via the mounting base. The seal has a clearance portion. By providing a clearance portion on the seal, when the seal is arranged, the clearance portion can be positioned between the mounting base and the receiving portion, and avoid the inlet and outlet channels on the cold plate, thereby providing a comprehensive seal for the cold plate and the frame, and improving the sealing performance between the frame, cold plate, and bottom guard plate.

[0055] The following describes exemplary application scenarios of this utility model.

[0056] The heat exchange component provided by this utility model can be applied to battery packs of new energy vehicles, such as battery packs for pure electric vehicles and battery packs for plug-in hybrid vehicles. Specifically, the heat exchange component provided by this utility model provides a clearance position on the seal. When the seal is arranged, the clearance position can be set between the mounting base and the receiving part and avoid the inlet and outlet channels on the cold plate, so as to provide a comprehensive seal for the cold plate and the frame, thereby improving the sealing performance between the frame, the cold plate and the bottom guard plate.

[0057] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0058] Reference Figure 1 and Figure 2 As shown, the heat exchange assembly 100 provided in this application includes a frame 110, a mounting base 120, a cold plate 130, a bottom protective plate 140, and a seal 150.

[0059] Mounting base 120 is disposed on one side of frame 110, cold plate 130 is disposed inside frame 110, bottom guard plate 140 has a receiving part 141 on one side, bottom guard plate 140 is disposed on frame 110 and covers cold plate 130, mounting base 120 is connected to receiving part 141.

[0060] The cold plate 130 is provided with a feeding channel 131 and a discharging channel 132. Both the feeding channel 131 and the discharging channel 132 are connected to the external cooling system through the mounting base 120.

[0061] The seal 150 has a clearance position 151. The seal 150 is disposed between the frame 110 and the bottom guard plate 140. The clearance position 151 is disposed between the mounting base 120 and the receiving part 141 to avoid the feed channel 131 and the discharge channel 132.

[0062] It is understood that the heat exchange assembly 100 provided in this application can be used in a battery pack, in which the battery cell assembly 200 is installed in the frame 110 and positioned above the cold plate 130, and the cold plate 130 cools the battery cell assembly 200.

[0063] Reference Figure 2As shown, the bottom guard plate 140 is connected to the bottom of the frame 110. The cold plate 130 is disposed at the bottom of the frame 110 through the bottom guard plate 140. The feed channel 131 and the discharge channel 132 on the cold plate 130 are both led out of the frame 110 through the mounting base 120 provided on the frame 110 for connection with an external cooling system. The cooling medium output from the external cooling system enters the cold plate 130 through the feed channel 131 to absorb the heat generated by the battery cell assembly 200, and then flows back to the cooling system through the discharge channel 132.

[0064] The receiving portion 141 on the bottom protective plate 140 is used to connect with the mounting base 120. The feed channel 131 and discharge channel 132 of the cold plate 130 are both located between the receiving portion 141 and the mounting base 120, which facilitates the cold plate 130 to be led out of the frame 110 and improves the stability of the installation. The sealing element 150 is disposed between the frame 110 and the bottom protective plate 140 to increase the sealing performance. The clearance portion 151 is disposed between the mounting base 120 and the receiving portion 141 and avoids the feed channel 131 and the discharge channel 132, thereby improving the sealing performance between the feed channel 131 and the discharge channel 132 and the mounting base 120.

[0065] This application provides a clearance 151 on the seal 150. When the seal 150 is arranged, the clearance 151 can be set between the mounting base 120 and the receiving part 141 and avoid the feeding channel 131 and the discharge channel 132 on the cold plate 130, so as to fully seal the cold plate 130 and the frame 110, thereby improving the sealing performance between the frame 110, the cold plate 130 and the bottom guard plate 140.

[0066] For example, refer to Figure 2 and Figure 5 As shown, the seal 150 can be a sealing gasket with an annular structure that matches the shape of the cold plate 130. The sealing gasket has a protruding clearance 151. Alternatively, the seal 150 can be a sealant, applied along the frame 110 and the bottom protective plate 140, and clearance is provided between the mounting base 120 and the receiving portion 141. Of course, the seal 150 can also have a structure similar to the above types; this embodiment does not impose excessive limitations on this.

[0067] The shape of the clearance 151 can be a rectangle, a square, or a parallelogram, as long as the shape of the clearance 151 matches the shape of the mounting base 120 and the receiving part 141. This application embodiment does not impose too many restrictions on this.

[0068] For example, the cold plate 130 can be connected to a water cooling system, a refrigerant system, or other similar cooling systems, as long as a cooling medium can be supplied to the cold plate 130 so that the cold plate 130 can cool the battery cell assembly 200. This application embodiment does not impose too many restrictions on this.

[0069] In some embodiments, refer to Figure 2 , Figure 3 and Figure 4 As shown, a docking part 133 is provided on one side of the cold plate 130, and the feeding channel 131 and the discharging channel 132 are both provided on the docking part 133.

[0070] The mounting base 120 is provided with a first through hole 121 and a second through hole 122. The mounting base 120 is provided with a mounting groove 123 on the side facing the bottom guard plate 140. The mating part 133 is provided in the mounting groove 123. The first through hole 121 is connected to the feeding channel 131, and the second through hole 122 is connected to the discharging channel 132.

[0071] In the above embodiment, the first through hole 121 and the second through hole 122 are respectively connected to the mounting groove 123. The mounting groove 123 is used for the installation of the docking part 133 and can play a positioning role, so that the first through hole 121 can be quickly connected to the feeding channel 131 and the second through hole 122 can be quickly connected to the discharging channel 132. The first through hole 121 and the second through hole 122 on the mounting base 120 can be used to connect to an external cooling system, so as to realize the connection between the cold plate 130 and the cooling system through the mounting base 120.

[0072] Among them, reference Figure 3 and Figure 4 As shown, the mating part 133 is disposed between the mounting base 120 and the receiving part 141, and the clearance part 151 of the sealing element 150 is arranged between the mounting base 120 and the receiving part 141, and avoids the mating part 133, thereby avoiding the feeding channel 131 and the discharging channel 132 of the cold plate 130 to improve the sealing performance.

[0073] Furthermore, referring to Figure 4 As shown, the mating part 133 is disposed in the mounting groove 123 so that the side surface of the mounting seat 120 facing the receiving part 141 is flat, avoiding gaps or uneven contact, so as to facilitate the arrangement of the clearance part 151 of the sealing element 150 between the mounting seat 120 and the receiving part 141, thereby improving the sealing performance.

[0074] For example, refer to Figure 3 and Figure 4 As shown, the first through hole 121 and the second through hole 122 can both be provided on the same side of the mounting base 120, which facilitates connection with the cooling system and reduces the complexity of the piping.

[0075] For example, refer to Figure 2 , Figure 3 and Figure 4 As shown, the bottom guard plate 140 and the receiving part 141 can be extruded integrally formed, and the cold plate 130 and the butt joint 133 can also be extruded integrally formed to ensure the strength of the connection.

[0076] In some embodiments, refer to Figure 4 As shown, a mounting position 111 is provided on the side of the frame 110 facing the bottom guard plate 140, and the cold plate 130 is disposed in the mounting position 111.

[0077] In the above embodiment, the mounting position 111 is used for the installation of the cold plate 130 and can play a positioning role to facilitate the installation of the cold plate 130 into the frame 110.

[0078] Specifically, refer to Figure 1 , Figure 2 and Figure 4 As shown, the frame 110 is formed by a number of side plates 112. Each side plate 112 has a recess on its inner side, and each recess forms a mounting position 111. The cold plate 130 is placed in the mounting position 111, and then the bottom guard plate 140 is placed on the side of each side plate 112 with a recess, thereby fixing the cold plate 130.

[0079] The shape of the mounting position 111 can be adapted to the shape of the cold plate 130 to avoid a large gap between the mounting position 111 and the cold plate 130, which would affect the sealing effect.

[0080] It is understandable that the cold plate 130 is set in the mounting position 111 so that the side surfaces of each side plate 112 of the frame 110 facing the bottom guard plate 140 are flat, avoiding gaps or uneven contact, so as to facilitate the arrangement of the seal 150 and thus improve the sealing performance.

[0081] In some embodiments, refer to Figure 4 and Figure 5 As shown, the seal 150 is arranged along the gap between the cold plate 130 and the mounting position 111, and the clearance position 151 is arranged along the gap between the mating part 133 and the mounting groove 123.

[0082] In the above embodiments, the seal 150 can effectively fill the gap between the cold plate 130 and the mounting position 111, and the clearance position 151 can effectively fill the gap between the mating part 133 and the mounting groove 123 to provide a better sealing effect.

[0083] For example, the mounting position 111 of the cold plate 130 and the frame 110, and the mating portion 133 of the cold plate 130 and the mounting seat 120 on the frame 110 can be connected by friction stir welding to improve the connection strength. The weld area is ground smooth, and the seal 150 can seal along the friction stir weld between the mounting position 111 of the cold plate 130 and the frame 110, and the clearance portion 151 can seal along the friction stir weld between the mating portion 133 and the mounting seat 120 to improve the sealing performance.

[0084] In some embodiments, refer to Figure 3 and Figure 4 As shown, the cold plate 130 includes a cold plate body 134 and a cooling channel 135 disposed within the cold plate body 134. The cooling channel 135 is used to cool the battery cell assembly 200.

[0085] The docking part 133 is located on one side of the cold plate body 134, and the feeding channel 131 and the discharging channel 132 are respectively connected to the cooling channel 135.

[0086] In the above embodiment, the cooling medium enters the cooling channel 135 in the cold plate body 134 through the feeding channel 131. The cooling medium flows in the cooling channel 135 and absorbs the heat generated by the battery cell assembly 200. Then it flows out through the discharge channel 132. This cycle is repeated to cool down the battery cell assembly 200.

[0087] Specifically, refer to Figure 4 As shown, the cold plate body 134 can be disposed within the mounting position 111 of the frame 110, and the sealing member 150 is arranged along the gap between the cold plate body 134 and the mounting position 111. In the battery pack, the cell assembly 200 can be disposed on the cold plate body 134 and aligned with the cooling channel 135, thereby cooling the cell assembly 200 through the cooling channel 135.

[0088] It is understood that the attached drawings only show a partial structure of the cooling channel 135. The cooling channel 135 can be a single-channel meandering shape, a multi-channel branch shape, or other types of shapes, as long as the cooling channel 135 can cool down multiple battery cell groups 200. This application embodiment does not impose too many restrictions on this.

[0089] In some embodiments, refer to Figure 3 As shown, the bottom guard plate 140 is provided with a first clearance groove 142 on the side facing the cold plate 130, and the receiving part 141 is provided with a second clearance groove 143 on the side facing the cold plate 130.

[0090] The cooling channel 135 is located in the first clearance groove 142, and the feeding channel 131 and the discharging channel 132 are both located in the second clearance groove 143.

[0091] In the above embodiment, by providing a first clearance groove 142 on the bottom protective plate 140, the bottom protective plate 140 avoids the cooling channel 135, and the bottom protective plate 140 does not directly contact the cooling channel 135, thereby reducing the heat conduction loss of the bottom protective plate 140. This can prevent heat from being transferred from the cooling channel 135 to the bottom protective plate 140, and maintain the cooling efficiency of the cooling channel 135.

[0092] It is understandable that the second clearance groove 143 provided on the receiving part 141 is also used to avoid the feeding channel 131 and the discharging channel 132, so as to reduce the heat conduction loss when the feeding channel 131 and the discharging channel 132 are in direct contact with the receiving part 141 and improve the cooling effect.

[0093] In some embodiments, refer to Figure 5 and Figure 6 As shown, the heat exchange assembly 100 provided in this application also includes a first fastener 160 and a second fastener 170.

[0094] The frame 110, seal 150 and bottom guard plate 140 are connected by a first fastener 160.

[0095] Mounting base 120 is connected to receiving part 141 by second fastener 170, and the second fastener 170 is located on the side of clearance 151 away from cold plate 130.

[0096] In the above embodiment, the frame 110, the seal 150, and the bottom guard plate 140 are connected by a first fastener to improve the stability of the connection between the three and prevent the seal 150 from loosening and affecting the sealing effect. The second fastener 170 is used to connect the mounting base 120 and the receiving part 141. The second fastener 170 does not contact the clearance part 151 and is located on the side of the clearance part 151 away from the cold plate 130. This can prevent additional gaps from being generated between the mounting base 120 and the receiving part 141, which would affect the sealing effect of the clearance part 151.

[0097] For example, refer to Figure 6 As shown, the first fastener 160 can be a rivet nut, the seal 150 can be a sealing gasket, and the frame 110 near the bottom guard plate 140, the seal 150 and the bottom guard plate 140 are all provided with fixing holes. The first fastener 160 passes through these fixing holes in sequence to connect the frame 110, the seal 150 and the bottom guard plate 140.

[0098] The second fastener 170 can also be a rivet nut. Both the mounting base 120 and the receiving part 141 have fixing holes to connect them. A wire threaded insert can be press-fitted into the fixing hole on the mounting base 120 to ensure reliable assembly and disassembly. Furthermore, the wire threaded insert is not exposed outside the fixing hole, making the surface of the mounting base 120 facing the receiving part 141 flush, facilitating the installation of the mounting base 120 and the receiving part 141. In actual use, the mounting base 120 and the receiving part 141 can be positioned on the windward side of the vehicle body; the use of an embedded wire threaded insert reduces corrosion.

[0099] Of course, the first fastener 160 and the second fastener 170 can also be other similar structures, and this application embodiment does not impose too many restrictions on them.

[0100] Specifically, refer to Figure 2 , Figure 3 and Figure 4 As shown, the edge of the bottom guard plate 140 is connected to the edge of the frame 110 by a first fastener 160. On the side of the bottom guard plate 140 away from the frame 110, the edge of the bottom guard plate 140 is recessed inward toward the frame 110 to form the mounting position 111 of the first fastener 160, so that the first fastener 160 does not protrude outward from the bottom guard plate 140 when installed, ensuring that the surface of the bottom guard plate 140 away from the frame 110 is flat.

[0101] In some embodiments, a mounting hole is provided on one side of the frame 110, and the mounting base 120 is inserted into the mounting hole.

[0102] In the above embodiments, the mounting holes are mainly used to set the mounting base 120 on the frame 110 to improve the stability of the installation.

[0103] Specifically, one side panel 112 of the frame 110 has a mounting hole, and the mounting base 120 is inserted into the mounting hole. The mounting base 120 and the side panel 112 can be connected by welding to improve the stability of the installation.

[0104] Reference Figure 7 As shown, this application provides a battery pack, including a cell assembly 200 and a heat exchange assembly 100 as described above. The cell assembly 200 is disposed within the frame 110 of the heat exchange assembly 100, and the cell assembly 200 is connected to the cold plate 130 of the heat exchange assembly 100.

[0105] In this embodiment, since the battery pack uses the heat exchange component 100 in the above embodiment, it also has the advantages and benefits brought by the heat exchange component 100, namely, good sealing effect.

[0106] Among them, reference Figure 7As shown, the battery pack may also include a top cover 300, which is disposed on the side of the frame 110 away from the bottom cover 140, and encapsulates the cell assembly 200 and the cold plate 130 through the bottom cover 140, the frame 110 and the top cover 300.

[0107] This application provides a vehicle including a vehicle body and the battery pack described above, the battery pack being disposed within the vehicle body.
