[0075] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure.

Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0076] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0077] See Figure 1 The illustration shows a representative perspective view of the heat exchange plate 100 proposed in this disclosure. In this exemplary embodiment, the heat exchange plate 100 proposed in this disclosure is described with an example of its application to an on-board power battery. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of this disclosure to other types of battery devices, and these changes are still within the scope of the principles of the heat exchange plate 100 proposed in this disclosure.

[0078] like Figure 1 As shown, in one embodiment of this disclosure, the heat exchange plate 100 includes a body 200 and a mounting structure 300. (See also...) Figures 2 to 7 , Figure 2 The exploded three-dimensional view of the heat exchange plate 100 is shown in the figure. Figure 3 A schematic plan view of the heat exchange plate 100 is shown in the figure. Figure 4 China representatively shows Figure 1 An enlarged schematic diagram of part A in the diagram; Figure 5 China representatively shows Figure 2 An enlarged schematic diagram of part B in the diagram; Figure 6 The middle section represents the direction along Figure 3 A schematic diagram of the cross-section made by the straight line CC in the diagram; Figure 7 China representatively shows Figure 6 An enlarged schematic diagram of part E in the figure. The structure, connection method, and functional relationship of the main components of the heat exchange plate 100 proposed in this disclosure will be described in detail below with reference to the above figures.

[0079] like Figures 1 to 7As shown, in one embodiment of this disclosure, the body 200 includes two stacked plates 210, each plate 210 having a central region 211 and an edge region 212 surrounding the central region 211. The two plates 210 together form a flow channel 201 in the central region 211. In the edge region 212, the opposing surfaces of the two plates 210 are respectively provided with corresponding grooves 213, and the two corresponding grooves 213 of the two plates 210 together form an assembly groove 202. The groove 213 opens at the periphery of the plate 210, so that the opening of the assembly groove 202 formed by the two grooves 213 is located at the periphery of the body 200. The mounting structure 300 includes a connecting portion 310 and a mounting portion 320, and the thermal conductivity of the material of the mounting structure 300 is less than that of the material of the body 200. The connecting portion 310 of the mounting structure 300 is disposed within the assembly groove 202. The mounting part 320 is connected to the connecting part 310 and is located around the periphery of the main body 200, that is, outside the assembly slot 202. The mounting part 320 is used to mount the battery box of the battery pack via a mounting member. That is, the heat exchange plate 100 is connected to the battery box (e.g., frame, beam, or other beam structure 400) via the mounting part 320 of the mounting structure 300. In the existing design of the battery pack, since the edge area where the heat exchange plate connects to the battery box is made of metal, the thermal conductivity of the material is high, resulting in more heat exchange between the heat exchange plate and the battery box through the edge area, causing heat loss and affecting the heat exchange efficiency between the heat exchange plate and the battery cells, which is not conducive to the cooling or heat preservation effect of the battery pack. Through the above design, the heat exchange plate 100 proposed in this disclosure is connected to the battery pack via the mounting structure 300. Utilizing the low thermal conductivity of its material, heat exchange between the heat exchange plate 100 and the battery pack is reduced, heat loss from the heat exchange plate 100 is minimized, and a high heat exchange efficiency is maintained between the heat exchange plate 100 and the battery cells, which is beneficial for the cooling or insulation effect of the battery pack. Furthermore, the heat exchange plate 100 proposed in this disclosure uses two plates 210 each with grooves 213 to jointly form an assembly groove 202 that accommodates part of the mounting structure 300. Simultaneously, the mounting structure 300 is injection molded, ensuring that its connecting part 310 is firmly bonded to the assembly groove 202, achieving a stable connection between the body 200 of the heat exchange plate 100 and the mounting structure 300. This improves the stability and reliability of the heat exchange plate 100 when installed in the battery pack via the mounting structure 300. For example, by adopting the heat exchange plate 100 proposed in this disclosure, the heat preservation performance of the battery pack in low-temperature static scenarios can be improved, and the driving range of the vehicle can be increased after restarting in cold northern regions or after being idle in winter.

[0080] like Figure 7As shown, in one embodiment of this disclosure, along the thickness direction of the plate 210 (e.g., referring to direction D2 shown in the accompanying drawings), the depth H1 of the groove 213 in the thickness H2 of the plate 210 can be 1 / 3 to 4 / 5, such as 1 / 3, 2 / 5, 1 / 2, 3 / 5, 5 / 8, 4 / 5, etc. Through the above design, this disclosure adopts a suitable range of proportions for the depth H1 of the groove 213, avoiding the difficulty or poor effect of the connection between the mounting structure 300 and the body 200 due to the groove depth H1 being too small, while avoiding the structural strength of the edge region 212 of the plate 210 being too large. In other embodiments of this disclosure, the depth H1 of the groove 213 in the thickness H2 of the plate 210 can also be less than 1 / 3 or greater than 4 / 5, such as 3 / 10, 5 / 6, etc., and is not limited to this embodiment.

[0081] In one embodiment of this disclosure, the depth H1 of the groove 213 along the thickness direction of the plate 210 can be greater than or equal to 0.2 mm, for example, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, etc. Through the above design, this disclosure uses a suitable numerical range for the depth H1 of the groove 213, avoiding situations where the depth H1 of the groove 213 is too small, making the connection between the mounting structure 300 and the body 200 difficult or resulting in poor connection. In other embodiments of this disclosure, the depth H1 of the groove 213 can also be less than 0.2 mm, for example, 0.19 mm, etc., and is not limited to this embodiment.

[0082] like Figure 7 As shown, in one embodiment of this disclosure, along a first direction parallel to the plate 210 and perpendicular to its periphery (referring to direction D1 in the accompanying drawings), the width W1 of the groove 213 can be 5mm to 15mm, such as 5mm, 6mm, 8mm, 10mm, 11mm, 13mm, 15mm, etc. Through the above design, this disclosure uses a suitable numerical range for the width W1 of the groove 213, avoiding a situation where the width W1 is too small, resulting in poor bonding between the mounting structure 300 and the body 200, while also avoiding a situation where the width W1 is too large, ensuring that the heat exchange plate 100 has sufficient space for arranging the flow channel 201. In other embodiments of this disclosure, the width W1 of the groove 213 can also be less than 5mm or greater than 15mm, such as 4.5mm, 16mm, etc., and is not limited to this embodiment.

[0083] It should be noted that the periphery of the plate 210 includes multiple edges, which do not extend in the same direction. When defining the first direction in this specification, the so-called "perpendicular to the periphery of the plate 210" can be understood as the direction that is parallel to the plate 210 and perpendicular to the extension direction of the edge corresponding to the groove 213.

[0084] See Figure 8 and Figure 9 , Figure 8 The diagram shows a three-dimensional exploded view of the heat exchange plate 100, which embodies the principles of this disclosure, in another exemplary embodiment. Figure 9 China representatively shows Figure 8 The diagram shown is a partially enlarged view of the cross-sectional structure of the heat exchange plate. For details, please refer to [reference needed]. Figure 7 Regarding Figure 6 The magnified area.

[0085] like Figure 8 and Figure 9 As shown, in one embodiment of this disclosure, the connecting portion 310 of the mounting structure 300 and the mounting groove 202 can be in a snap-fit ​​engagement. For example, the dimensions of different areas of the mounting groove 202 can be designed differently along the thickness direction of the plate 210 to achieve a snap-fit ​​engagement between the mounting groove 202 and the connecting portion 310. Alternatively, the dimensions of different areas of the mounting groove 202 can be designed differently along the width direction or other directions of the plate 210 to achieve a snap-fit ​​engagement.

[0086] like Figure 9 As shown, in one embodiment of this disclosure, in the two grooves 213 that together form the assembly groove 202, each groove 213 has a first groove portion 2131 and a second groove portion 2132. Along a first direction parallel to the plate body 210 and perpendicular to the periphery of the plate body 210, the first groove portion 2131 is closer to the opening of the assembly groove 202 than the second groove portion 2132. Along the thickness direction of the plate body 210, the groove depth of the second groove portion 2132 is greater than the groove depth of the first groove portion 2131. Based on this, the first groove portions 2131 of the two grooves 213 together form the communicating groove portion 2021 of the assembly groove 202, and the second groove portions 2132 of the two grooves 213 together form the limiting groove portion 2022 of the assembly groove 202. Furthermore, the connecting portion 310 includes a communicating portion located in the communicating groove portion 2021 and a limiting portion located in the limiting groove portion 2022, the limiting portion engaging with the limiting groove portion 2022.

[0087] like Figure 9As shown, based on the design that both grooves 213 forming the assembly groove 202 have a first groove portion 2131 and a second groove portion 2132, in one embodiment of this disclosure, the structures of the two grooves 213 forming the assembly groove 202 can be identical. For example, the cross-sectional shape and size of the two grooves 213 are exactly the same. Accordingly, the assembly groove 202 has a mirror-symmetric structure, and the plane of symmetry is the plane where the interface of the two plates 210 is located. Through the above design, this disclosure can achieve a design where the grooves 213 of the two plates 210 have the same structure, which is suitable for the two plates 210 to be manufactured using the same or similar processes, which helps to reduce production costs and improve the efficiency of mass production.

[0088] Furthermore, based on the identical structure of the two grooves 213 that jointly form the assembly groove 202, in one embodiment of this disclosure, the thickness of the two plates 210 can be equal. Through the above design, this disclosure can achieve a design where the two plates 210 have the same structure. Of course, the above description of the identical structure of the two plates 210 refers to the identical structure of the edge regions 212 of the plates 210. To form the flow channel 201, the two plates 210 can be provided with the same channel 214, or they can be provided with different channels 214, or only one of them can be provided with a channel 214 while the other is not provided with a channel 214. Furthermore, if the channel 214 is further integrally stamped into the plate 210, then before the process of stamping out the channel 214, based on the above-mentioned identical structure of the two plates 210, the raw material plates of the two plates 210 can still be produced and processed using the same process.

[0089] like Figure 8 and Figure 9 As shown, in one embodiment of this disclosure, the assembly groove 202 may have a communicating groove portion 2021 and a limiting groove portion 2022. Along a first direction, the communicating groove portion 2021 is closer to the opening of the assembly groove 202 than the limiting groove portion 2022. For example, one end of the communicating groove portion 2021 communicates with the limiting groove portion 2022, and the other end opens at the edge of the body 200 to form the opening of the assembly groove 202. Along the thickness direction of the plate body 210, the dimension H3 of the limiting groove portion 2022 may be larger than the dimension H4 of the communicating groove portion 2021. Correspondingly, the connecting portion 310 may include a communicating portion located in the communicating groove portion 2021 and a limiting portion located in the limiting groove portion 2022. Along the thickness direction, the thickness of the limiting portion is greater than the thickness of the communicating portion. Through the above design, this disclosure can utilize the dimensional difference between the two grooves of the assembly groove 202 along the thickness direction of the plate 210 to achieve the limiting and anti-reverse functions, making the connection and fixation between the mounting structure 300 and the assembly groove 202 more secure, and achieving locking of the mounting structure 300, making it less likely to be pulled out.

[0090] It should be noted that, with Figure 9Taking the rectangular cross-sectional shapes of the connecting groove 2021 and the limiting groove 2022 as examples, the dimensions H3 of the limiting groove 2022 and H4 of the connecting groove 2021 can be understood as their dimensions at their respective positions. It should be understood that when a portion of the assembly groove 202 adopts a non-uniform cross-sectional shape, such as a triangle or a circle, the dimensions H3 and H4 can be understood as the dimensions at the maximum size of the corresponding groove, that is, the maximum size in the thickness direction of the plate 210.

[0091] like Figure 9 As shown, based on the design of the assembly groove 202 including the connecting groove 2021 and the limiting groove 2022, in one embodiment of this disclosure, along the thickness direction, the ratio of the dimension H3 of the limiting groove 2022 to the dimension H4 of the connecting groove 2021 can be 6 / 5 to 2 / 1, for example, 6 / 5, 5 / 4, 4 / 3, 3 / 2, 8 / 5, 7 / 4, 2 / 1, etc. Through the above design, this disclosure adopts a suitable ratio range for the dimensions of the limiting groove 2022 and the connecting groove 2021, avoiding the ratio being too large. When the ratio is too large, the dimension H4 of the connecting groove 2021 may be too small, which will increase the difficulty of joining the mounting structure 300. The dimension H3 of the limiting groove 2022 may be too large, resulting in poor structural strength of the part of the plate 210 where the limiting groove 2022 is provided. Meanwhile, this disclosure avoids the aforementioned ratio being too small. If the ratio is too small, the thickness difference between the connecting groove 2021 and the limiting groove 2022 will not be significant enough, which may affect the limiting and anti-reverse function. In other embodiments of this disclosure, the ratio of the dimension H3 of the limiting groove 2022 to the dimension H4 of the connecting groove 2021 may also be less than 6 / 5 or greater than 2 / 1, such as 7 / 6, 13 / 6, etc., and is not limited to this embodiment.

[0092] like Figure 9As shown, based on the design of the assembly groove 202 including the connecting groove portion 2021 and the limiting groove portion 2022, in one embodiment of this disclosure, along the first direction, the ratio of the width W2 of the limiting groove portion 2022 to the width W3 of the connecting groove portion 2021 can be 1 / 2 to 2 / 1, for example, 1 / 2, 3 / 5, 3 / 4, 4 / 5, 5 / 4, 4 / 3, 5 / 3, 2 / 1, etc. Through the above design, this disclosure adopts a suitable ratio range for the widths of the limiting groove portion 2022 and the connecting groove portion 2021, avoiding the ratio being too small. If the ratio is too small, the limiting groove portion 2022 will be too small (i.e., the limiting portion is too small), which may affect the limiting and anti-reverse function. At the same time, this disclosure avoids the ratio being too large, as a large ratio will lead to an increase in the amount of raw materials used in the mounting structure 300. In other embodiments of this disclosure, the ratio of the width W2 of the limiting groove 2022 to the width W3 of the connecting groove 2021 may be less than 1 / 2 or greater than 2 / 1, for example, 2 / 5, 5 / 2, etc., and is not limited to this embodiment.

[0093] Furthermore, in one embodiment of this disclosure, the ratio of the width W2 of the limiting groove 2022 to the width W3 of the connecting groove 2021 can be specifically 1 / 1, that is, the width W2 of the limiting groove 2022 is equal to the width W3 of the connecting groove 2021.

[0094] like Figure 9 As shown, based on the design of the assembly groove 202 including the connecting groove portion 2021 and the limiting groove portion 2022, in one embodiment of this disclosure, the cross-sectional shape of the limiting groove portion 2022 can be rectangular.

[0097] like Figure 10 As shown, in one embodiment of this disclosure, the assembly groove 202 includes a limiting groove 2022 as an example. The cross-sectional shape of the limiting groove 2022 can also be triangular, and the large end of the triangle is connected to the connecting groove 2021.

[0099] like Figure 11 As shown, in one embodiment of this disclosure, the assembly groove 202 includes a limiting groove 2022 as an example. The cross-sectional shape of the limiting groove 2022 can also be trapezoidal, and the small end of the trapezoid is connected to the communicating groove 2021.

[0102] See Figure 13 , Figure 13 The diagram shows a partially enlarged cross-sectional view of the heat exchange plate 100, which embodies the principles of this disclosure, in another exemplary embodiment. See also: Figure 7 Regarding Figure 6 The magnified area.

[0103] like Figure 13 As shown, in one embodiment of this disclosure, taking the assembly groove 202 including the limiting groove portion 2022 as an example, the cross-sectional shape of the limiting groove portion 2022 can also be elliptical, and one end of the ellipse in the major axis direction is connected to the communicating groove portion 2021. In other embodiments, the cross-sectional shape of the limiting groove portion 2022 can also be circular.

[0104] See Figure 14 , Figure 14 The diagram shows a partially enlarged cross-sectional view of the heat exchange plate 100, which embodies the principles of this disclosure, in another exemplary embodiment. See also: Figure 7 Regarding Figure 6 The magnified area.

[0105] like Figure 14 As shown, different from Figures 7 to 13In the various embodiments shown, the grooves 213 of the two plates 210 are each provided with a first groove 2131 and a second groove 2132. In one embodiment of this disclosure, for the two grooves 213 of the two plates 210 that together form the assembly groove 202, only one of them may be provided with a first groove 2131 and a second groove 2132, while the other may be a groove structure with a uniform depth.

[0106] like Figure 7 As shown, in one embodiment of this disclosure, along the first direction, the ratio of the width W4 of the mounting portion 320 to the width of the connecting portion 310 (the width of the connecting portion 310 is equal to the width of the mounting groove 202, i.e., equal to the width W1 of the recess 213) can be 1 / 1 to 3 / 1, for example, 1 / 1, 5 / 4, 7 / 5, 3 / 2, 9 / 5, 2 / 1, 5 / 2, 3 / 1, etc. Through the above design, this disclosure adopts a suitable ratio between the widths of the connecting portion 310 and the mounting portion 320, which can avoid the mounting portion 320 being too small, making it difficult to install with the battery box, and at the same time, it can avoid the mounting portion 320 being too large, causing space waste, or the connecting portion 310 being too small, affecting the connection between the mounting structure 300 and the mounting groove 202. In other embodiments of this disclosure, the ratio of the width W4 of the mounting portion 320 to the width of the connecting portion 310 may be less than 1 / 1 or greater than 3 / 1, for example 9 / 10, 10 / 3, etc., and is not limited to this embodiment.

[0107] like Figure 7 As shown, in one embodiment of this disclosure, the width W4 of the mounting portion 320 along the first direction can be 10mm to 30mm, such as 10mm, 15mm, 20mm, 25mm, 30mm, etc. Through the above design, this disclosure uses a suitable width range for the mounting portion 320, avoiding the difficulty of installing it with the battery housing due to an excessively small width W4, while also avoiding the space occupation or impact on the overall strength of the heat exchange plate 100 due to an excessively large width W4. In other embodiments of this disclosure, the width W4 of the mounting portion 320 can also be less than 10mm or greater than 30mm, such as 9mm, 32mm, etc., and is not limited to this embodiment.

[0108] like Figure 7 As shown, in one embodiment of this disclosure, along the thickness direction of the plate 210, the two side surfaces of the mounting portion 320 can be flush with the opposite side surfaces of the two plates 210, respectively. For example, the thickness of the mounting portion 320 can be equal to the thickness of the main body 200, that is, equal to the sum of the thicknesses of the two plates 210.

[0109] In one embodiment of this disclosure, the thickness H2 of a single plate 210 can be 1mm to 2mm, such as 1mm, 1.3mm, 1.5mm, 1.6mm, 1.8mm, 2mm, etc. Through the above design, this disclosure avoids situations where the thickness H2 of the plate 210 is too small, making it difficult to arrange the groove 213 or resulting in insufficient structural strength of the plate 210. Simultaneously, it avoids situations where the thickness H2 of the plate 210 is too large, leading to material waste, increased weight, and impaired heat exchange between the heat exchange medium and the battery cells. In other embodiments of this disclosure, the thickness H2 of a single plate 210 can also be less than 1mm or greater than 2mm, such as 0.9mm, 2.1mm, etc., and is not limited to this embodiment.

[0110] like Figure 7 As shown, in one embodiment of this disclosure, the mounting portion 320 may be provided with a mounting hole 321 for mounting a mounting component, which may be a rivet. In other embodiments of this disclosure, the connecting component may also be a bolt or a pin, etc. Of course, when the mounting structure 300 adopts... Figure 7 In the structure shown, the portion of the mounting structure 300 located outside the assembly slot 202 may also be provided with mounting holes 321.

[0111] In one embodiment of this disclosure, the mounting structure 300 can be made of plastic, and the mounting structure 300 is formed by injection molding so that the connecting part 310 is engaged in the assembly groove 202. It should be noted that, because plastic raw materials have fluidity in the injection molding process, the injection and shaping of the plastic raw material can be achieved through a mold. For example, the mounting part 320 can be formed through a mold, while the connecting part 310 can be formed through the assembly groove 202. Through the above design, the heat exchange plate 100 proposed in this disclosure is connected to the battery box through the plastic mounting structure 300. Utilizing the low thermal conductivity of plastic, the heat exchange between the heat exchange plate 100 and the battery box is effectively reduced, while ensuring insulation performance.

[0112] In one embodiment of this disclosure, the mounting structure 300 can be made of PP, PBT, PA6, or PA66. Alternatively, the mounting structure 300 can also be made of PP, PBT, PA6, or PA66 with added glass fiber. Through the above design, this disclosure uses a plastic material with good flowability and wettability to form the mounting structure 300, which is beneficial for its molding effect in the injection molding process.

[0113] like Figure 6As shown, in one embodiment of this disclosure, a channel 214 is provided on the surface of one plate 210 facing another plate 210. This channel 214 and the opposite surface of the other plate 210 together form a flow channel 201. Specifically, taking the heat exchange plate 100 being disposed at the bottom of the battery housing as an example, the two plates 210 are stacked vertically. Based on this, a downwardly recessed channel 214 can be provided on the lower plate 210, and this channel 214 and the lower surface of the upper plate 210 together form the flow channel 201. In other embodiments of this disclosure, channels 214 can also be provided on the opposing surfaces of the two plates 210, and the channels 214 of the two plates 210 together form the flow channel 201.

[0114] like Figures 1 to 5 As shown, in one embodiment of this disclosure, the body 200 may be provided with an assembly groove 202, and the assembly groove 202 is arranged around the body 200. In other words, the assembly groove 202 is an annular groove surrounding the periphery of the body 200. Based on this, when the assembly groove 202 includes a limiting groove portion 2022 and a communicating groove portion 2021, the limiting groove portion 2022 is also an annular groove, and the communicating groove portion 2021 is also an annular groove (or an annular channel). Based on this, the heat exchange plate 100 may include a mounting structure 300, which includes a connecting portion 310 and a mounting portion 320, the mounting portion 320 being arranged around the body 200. In other words, the mounting structure 300 can be an annular structure, and both the connecting portion 310 and the mounting portion 320 are annular structures. The mounting portion 320 is arranged around the periphery of the plate body 210 and is fixed to the annular assembly groove 202 via the annular connecting portion 310. Through the above design, this disclosure can reduce structural complexity, reduce the number of parts, reduce manufacturing costs, and help improve production efficiency.

[0115] In other embodiments of this disclosure, taking the example of a body 200 having an annular assembly groove 202 and a heat exchange plate 100 including a mounting structure 300, the mounting structure 300 may include an annular connecting portion 310 and multiple mounting portions 320. The multiple mounting portions 320 are respectively connected to the connecting portion 310 and arranged at intervals along the circumference of the body 200. Furthermore, the body 200 may also have multiple assembly grooves 202, which are arranged at intervals along the circumference of the body 200. Based on this, the heat exchange plate 100 may include a mounting structure 300, which includes multiple connecting portions 310 and a mounting portion 320. The multiple connecting portions 310 are respectively arranged corresponding to the multiple assembly grooves 202, and the mounting portion 320 is arranged around the body 200 and simultaneously connects to the multiple connecting portions 310. In other words, the mounting structure 300 can be a ring structure, surrounding the periphery of the plate 210, and is connected and fixed to the plate 210 via multiple connecting parts 310. Furthermore, taking the body 200 as an example with multiple mounting slots 202, the heat exchange plate 100 may also include multiple mounting structures 300, which are arranged corresponding to the multiple mounting slots 202.

[0116] It should be noted that the heat exchanger 100 shown in the accompanying drawings and described in this specification is merely a few examples among many heat exchangers 100 capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the heat exchanger 100 shown in the accompanying drawings or described in this specification.

[0117] For example, taking a heat exchange plate 100 used in a certain type of battery pack as an example, the specific dimensions of each main component of the heat exchange plate 100 are as follows: along the thickness direction, the thickness H2 of the two plates 210 is equal, and the thickness H2 is 1.2mm each. The grooves 213 provided on the two plates 210 have the same structure, and the grooves 213 include a first groove 2131 and a second groove 2132, that is, the assembly groove 202 includes a connecting groove 2021 and a limiting groove 2022. Among them, the depth of the first groove 2131 is 0.5mm, the depth of the second groove 2132 is 0.8mm, that is, the dimension H4 of the connecting groove 2021 is 1mm, and the dimension H3 of the limiting groove 2022 is 1.6mm. Furthermore, along the first direction, the width W1 of the groove 213 is 10mm, meaning the width of the assembly groove 202 is 10mm. Based on this, the width W2 of the limiting groove 2022 is equal to the width W3 of the connecting groove 2021, meaning the width W2 of the limiting groove 2022 is 5mm and the width W3 of the connecting groove 2021 is 5mm. Additionally, along the first direction, the width W4 of the mounting portion 320 is 22mm, and the width of the connecting portion 310 is equal to the width of the assembly groove 202 (i.e., the width W1 of the groove 213), which is 10mm. Since the mounting structure 300 adopts a design where its two side surfaces are flush with the opposite side surfaces of the two plates 210, the thickness of the mounting structure 300 is the sum of the thicknesses H2 of the two plates 210, which is 2.4mm.

[0118] Based on the above detailed description of several exemplary embodiments of the heat exchange plate 100 proposed in this disclosure, an exemplary embodiment of the battery pack proposed in this disclosure will be described below.

[0119] like Figure 15 As shown, in one embodiment of this disclosure, the battery pack proposed in this disclosure includes the heat exchange plate 100 proposed in this disclosure and described in detail in the above embodiments.

[0120] like Figure 16 As shown, in one embodiment of this disclosure, the battery pack housing includes a beam structure 400, which can be a frame, an internal beam (e.g., a crossbeam), etc. The mounting structure 300 of the heat exchange plate 100 is connected to the beam structure 400 via connectors (e.g., rivets). Based on this, the body 200 and the beam structure 400 have a projected overlap. A heat-insulating sealing layer 420 can be provided at this projected overlap location between the body 200 and the beam structure 400 to prevent direct contact between the body 200 of the heat exchange plate 100 and the beam structure 400, further reducing heat loss and achieving a sealing function. In other embodiments of this disclosure, the body 200 and the beam structure 400 can also be staggered, for example, on the plane where the plate 210 is located. The body 200 of the heat exchange plate 100 and the beam structure 400 do not have an overlapping area, and this is not limited to this embodiment.

[0121] In one embodiment of this disclosure, the heat insulation sealing layer 420 may be made of a heat insulation material with a cushioning function, such as cushioning foam.

[0122] It should be noted that the battery packs shown in the accompanying drawings and described in this specification are merely a few examples among many battery packs capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the battery packs shown in the accompanying drawings or described in this specification.

[0123] Based on the above detailed description of an exemplary embodiment of the battery pack proposed in this disclosure, an exemplary embodiment of the vehicle proposed in this disclosure will be described below.

[0124] In one embodiment of this disclosure, the vehicle proposed in this disclosure includes the battery pack proposed in this disclosure and described in the above embodiments.

[0125] Figure 17 This is a block diagram illustrating a vehicle 600 according to an exemplary embodiment. For example, vehicle 600 may be a hybrid vehicle, an electric vehicle, a fuel cell vehicle, or other types of vehicle. Vehicle 600 may be an autonomous vehicle, a semi-autonomous vehicle, or a non-autonomous vehicle.

[0126] Reference Figure 17 The vehicle 600 may include various subsystems, such as an infotainment system 610, a perception system 620, a decision control system 630, a drive system 640, and a computing platform 650. The vehicle 600 may also include more or fewer subsystems, and each subsystem may include multiple components. Furthermore, each subsystem and each component of the vehicle 600 can be interconnected via wired or wireless means.

[0127] In some embodiments, the infotainment system 610 may include a communication system, an entertainment system, and a navigation system, etc.

[0128] The perception system 620 may include several sensors for sensing information about the environment surrounding the vehicle 600. For example, the perception system 620 may include a global positioning system (which may be GPS, BeiDou, or other positioning systems), an inertial measurement unit (IMU), lidar, millimeter-wave radar, ultrasonic radar, and a camera device.

[0129] The decision control system 630 may include a computing system, a vehicle controller, a steering system, a throttle, and a braking system.

[0130] The drive system 640 may include components that provide powered motion to the vehicle 600. In one embodiment, the drive system 640 may include an engine, an energy source, a transmission system, and wheels. The engine may be one or a combination of internal combustion engines, electric motors, and compressed air engines. The engine is capable of converting energy provided by the energy source into mechanical energy. The energy source may include the battery pack disclosed herein.

[0131] Some or all of the functions of vehicle 600 are controlled by computing platform 650. Computing platform 650 may include at least one processor 651 and memory 652, processor 651 can execute instructions 653 stored in memory 652.

[0132] Processor 651 can be any conventional processor, such as a commercially available CPU. Processors may also include graphics processing units (GPUs), field-programmable gate arrays (FPGAs), systems-on-chips (SoCs), application-specific integrated circuits (ASICs), or combinations thereof.

[0133] The memory 652 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, magnetic disk or optical disk.

[0134] In addition to instruction 653, memory 652 can also store data, such as road maps, route information, vehicle position, direction, speed, and other data. The data stored in memory 652 can be used by computing platform 650.

[0135] It should be noted that the vehicles shown in the accompanying drawings and described in this specification are merely a few examples among many vehicles capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the vehicles shown in the accompanying drawings or described in this specification.

[0136] In summary, the heat exchange plate 100 proposed in this disclosure includes a body 200 and a mounting structure 300. The body 200 includes two stacked plates 210. In the edge region 212 of the plates 210, the opposing surfaces of the two plates 210 are respectively provided with corresponding grooves 213, and the two corresponding grooves 213 of the two plates 210 together form an assembly groove 202. The grooves 213 open at the periphery of the plates 210, so that the groove opening of the assembly groove 202 is located at the periphery of the body 200. The mounting structure 300 includes a connecting part 310 and a mounting part 320. The thermal conductivity of the material of the mounting structure 300 is less than that of the material of the body 200. The connecting part 310 is disposed in the assembly groove 202. The mounting part 320 is connected to the connecting part 310 and is located at the periphery of the body 200. The mounting part 320 is used to be mounted to the battery box of the battery pack via a mounting member. Through the above design, the heat exchange plate 100 proposed in this disclosure is connected to the battery pack via the mounting structure 300. Utilizing the low thermal conductivity of its material, heat exchange between the heat exchange plate 100 and the battery pack is reduced, heat loss from the heat exchange plate 100 is minimized, and a high heat exchange efficiency is maintained between the heat exchange plate 100 and the battery cells, which is beneficial for the cooling or insulation effect of the battery pack. Furthermore, the heat exchange plate 100 proposed in this disclosure uses two plates 210 each with grooves 213 to jointly form an assembly groove 202 that accommodates part of the mounting structure 300. Simultaneously, the mounting structure 300 is injection molded, ensuring that its connecting part 310 is firmly bonded to the assembly groove 202, achieving a stable connection between the body 200 of the heat exchange plate 100 and the mounting structure 300. This improves the stability and reliability of the heat exchange plate 100 when installed in the battery pack via the mounting structure 300.

[0137] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0138] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”

[0139] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0140] It should be understood that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein according to the specific circumstances.

[0141] Although terms such as “first” and “second” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0142] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0143] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
