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

[0045] The heat exchange structure 100 proposed in the present invention is described by taking the application in a vehicle battery as an example. It is easy for those skilled in the art to understand that in order to apply the relevant design of the present invention to other types of battery devices, various modifications, additions, substitutions, deletions or other changes are made to the specific implementations described below, and these changes are still within the scope of the principle of the heat exchange structure 100 proposed in the present invention.

[0046] See also Figures 1 to 4 , Figure 1 A three-dimensional structural schematic diagram of a heat exchange structure 100 that can embody the principle of the utility model is representatively shown in FIG. Figure 2 , a three-dimensional exploded schematic diagram of the heat exchange structure 100 in a viewing angle (eg, a top view) is representatively shown; Figure 3 , a three-dimensional exploded schematic diagram of the heat exchange structure 100 in another viewing angle (eg, a bottom viewing angle) is representatively shown; Figure 4 A partial cross-sectional view of the heat exchange structure 100 (e.g., a top view), which specifically shows the cross-sectional structure at the edge of the heat exchange structure 100. The structure, connection method and functional relationship of each main component of the heat exchange structure 100 proposed by the utility model will be described in detail below in conjunction with the above drawings.

[0047] like Figures 1 to 4As shown, in one embodiment of the present invention, the heat exchange structure 100 proposed by the present invention includes a heat exchange plate 110, a honeycomb plate 120, a protective plate 130 and an encapsulation layer 140. Specifically, the heat exchange plate 110 has a heat exchange flow channel for circulating a heat exchange medium. For example, the heat exchange plate 110 may include two plates that are relatively combined, one of which is a channel plate 111. The surface of the channel plate 111 facing the other plate is provided with a channel 1111. The other plate may be, for example but not limited to, a flat plate. The channel 1111 of the channel plate 111 and the other plate together form the heat exchange flow channel of the heat exchange plate 110. In order to clearly show the heat exchange flow channel (channel 1111), the other plate of the heat exchange plate 110 is hidden in each figure and only the channel plate 111 is shown. Accordingly, the honeycomb plate 120 is disposed on the first surface 1101 of the heat exchange plate 110 in the first direction X (i.e., the surface of the channel plate 111 facing away from another plate), and the honeycomb plate 120 has a second surface 1201 facing away from the heat exchange plate 110. The protective plate 130 is disposed on the second surface 1201 of the honeycomb plate 120, and the protective plate 130 has a third surface 1301 facing away from the honeycomb plate 120. The material hardness of the protective plate 130 is greater than the material hardness of the honeycomb plate 120. A portion of the encapsulation layer 140 is disposed on the third surface 1301 of the protective plate 130. On this basis, the area of ​​the protective plate 130 is smaller than the area of ​​the second surface 1201 of the honeycomb panel 120, and the plane where the second surface 1201 is located is taken as the reference plane. On this reference plane, the orthographic projection of the protective plate 130 is located within the range of the second surface 1201, the orthographic projection edge of the encapsulation layer 140 exceeds the orthographic projection edge of the protective plate 130, and the portion of the encapsulation layer 140 that exceeds is at least connected to the area of ​​the second surface 1201 that is not covered by the protective plate 130. Through the above structural design, the utility model can use the protective plate 130 to provide protection for the honeycomb panel 120, so that the heat exchange structure 100 has better anti-ball hitting ability. On this basis, the utility model uses the encapsulation layer 140 to cover the gap between the honeycomb panel 120 and the protective plate 130, thereby avoiding the intrusion of foreign matter or water vapor, and further avoiding the intrusion into the heat exchange plate 110, thereby ensuring the buffering effect of the honeycomb panel 120, while ensuring the heat exchange effect of the heat exchange plate 110.

[0048] like Figure 3 and Figure 4As shown, in one embodiment of the present invention, the encapsulation layer 140 has a first portion 141 and a second portion 142, the first portion 141 being the portion where the encapsulation layer 140 overlaps with the orthographic projection of the protective plate 130, and the second portion 142 being the portion where the encapsulation layer 140 exceeds the orthographic projection edge of the protective plate 130 and is connected to the second surface 1201. On this basis, the second portion 142 of the encapsulation layer 140 can cover the entire area of ​​the second surface 1201 that is not covered by the protective plate 130. Through the above structural design, the present invention can ensure that the encapsulation layer 140 covers all gaps between the protective plate 130 and the honeycomb panel 120. Furthermore, when the axial direction of the honeycomb pores of the honeycomb panel 120 is arranged along the first direction X, that is, along the stacking direction of the heat exchange plate 110, the honeycomb panel 120, and the protective plate 130, the encapsulation layer 140 can ensure full coverage of the pores of the honeycomb panel 120 in the area not covered by the protective plate 130, further preventing foreign matter or water vapor from invading the honeycomb pores of the honeycomb panel 120 and thus affecting the heat exchange plate 110.

[0049] See also Figure 5 , Figure 5 2 is a partial cross-sectional view of another exemplary embodiment of a heat exchange structure 100 that can embody the principle of the present invention.

[0050] like Figure 5 As shown, still taking the encapsulation layer 140 having the first part 141 and the second part 142 as an example, in one embodiment of the present invention, the honeycomb panel 120 has a second side surface 1202, and the second side surface 1202 is parallel to the first direction X and perpendicular to the second surface 1201 of the honeycomb panel 120. On this basis, the second part 142 of the encapsulation layer 140 can also cover the second side surface 1202 of the honeycomb panel 120. Through the above structural design, the present invention can further enhance the encapsulation effect and protective effect of the encapsulation layer 140.

[0051] See also Figure 6 , Figure 6 2 is a partial cross-sectional view of another exemplary embodiment of a heat exchange structure 100 that can embody the principle of the present invention.

[0052] like Figure 5 As shown, still taking the encapsulation layer 140 having the first portion 141 and the second portion 142 as an example, in one embodiment of the present utility model, the heat exchange plate 110 has a first side surface 1102, and the first side surface 1102 is parallel to the first direction X and perpendicular to the first surface 1101. In order to more completely show the first side surface 1102 of the heat exchange plate 110, Figure 6FIG. 1 shows another plate 111 of the heat exchange plate 110. On this basis, the second portion 142 of the encapsulation layer 140 can also cover the first side surface 1102 of the heat exchange plate 110. Specifically, Figure 5 In the structure shown, the edge of the honeycomb panel 120 exceeds the edge of the heat exchange plate 110, and accordingly, the second portion 142 of the encapsulation layer 140 also covers the edge portion of the honeycomb panel 120 on the side of the surface facing the heat exchange plate 110 that exceeds the edge. In some embodiments, the edge of the honeycomb panel 120 may also be flush with the edge of the heat exchange plate 110, or the edge of the heat exchange plate 110 may also exceed the edge of the honeycomb panel 120, and the present invention is not limited thereto. Through the above structural design, the utility model can further enhance the encapsulation effect and protective effect of the encapsulation layer 140.

[0053] See also Figure 6 , Figure 6 2 is a partial cross-sectional view of another exemplary embodiment of a heat exchange structure 100 that can embody the principle of the present invention.

[0054] like Figure 6 As shown, still taking the encapsulation layer 140 having the first part 141 and the second part 142 as an example, in one embodiment of the present utility model, the heat exchange plate 110 has a fourth surface 1103 facing away from the honeycomb plate 120, that is, a side surface of the heat exchange plate 110 facing away from the channel plate 111. In order to more completely show the first side surface 1102 of the heat exchange plate 110, Figure 6 1 shows another plate 111 of the heat exchange plate 110, and the fourth surface 1103 of the heat exchange plate 110 is the surface of the plate 111 facing away from the channel plate 111. On this basis, the second portion 142 of the encapsulation layer 140 can also cover the edge area of ​​the fourth surface 1103 of the heat exchange plate 110. Through the above structural design, the utility model can further improve the encapsulation effect and protective effect of the encapsulation layer 140.

[0055] In one embodiment of the present invention, the material of the protective plate 130 can be metal, such as but not limited to steel plate, and can further be alloy materials such as stainless steel, thereby ensuring sufficient material hardness to meet protection needs while taking into account rust prevention and corrosion resistance.

[0056] In one embodiment of the present invention, the packaging layer 140 may be a cover made of insulating material, which is convenient for arrangement, has better ductility and conformability, and can also take into account insulation performance.

[0057] In one embodiment of the present invention, the encapsulation layer 140 and the honeycomb panel 120 may be connected by gluing or hot-melt pressing. For example, some existing honeycomb panels 120 have a layer of adhesive film on their surface, and the encapsulation layer 140 may be directly glued to the desired position of the honeycomb panel 120 through the adhesive film.

[0058] In one embodiment of the present invention, the encapsulation layer 140 can be connected to the third surface 1301 of the protective plate 130. On this basis, the encapsulation layer 140 and the protective plate 130 can be connected by gluing or hot-melt pressing. In some embodiments, the encapsulation layer 140 and the protective plate 130 may also have no connection relationship, that is, the encapsulation layer 140 can only be connected to the honeycomb panel 120 to achieve encapsulation and fixation in the heat exchange structure 100, which is not limited to this embodiment.

[0059] It should be noted that the heat exchange structures 100 shown in the drawings and described in this specification are only a few examples of the many types of heat exchange structures 100 that can adopt the principles of the present invention. It should be clearly understood that the principles of the present invention are by no means limited to any details or any components of the heat exchange structures 100 shown in the drawings or described in this specification.

[0060] In summary, the heat exchange structure 100 proposed in the utility model includes a heat exchange plate 110, a honeycomb plate 120, a protective plate 130 and a packaging layer 140 stacked in sequence. The material hardness of the protective plate 130 is greater than the material hardness of the honeycomb plate 120. A portion of the packaging layer 140 covers the protective plate 130, and the other portion exceeds the edge of the protective plate 130 and is connected to the area of ​​the honeycomb plate 120 that is not covered by the protective plate 130. Through the above structural design, the utility model can use the protective plate 130 to provide protection for the honeycomb plate 120, so that the heat exchange structure 100 has better anti-ball hitting ability. On this basis, the utility model uses the packaging layer 140 to cover the gap between the honeycomb plate 120 and the protective plate 130, thereby avoiding the intrusion of foreign matter or water vapor, and further avoiding the intrusion into the heat exchange plate 110, thereby ensuring the buffering effect of the honeycomb plate 120, while ensuring the heat exchange effect of the heat exchange plate 110.

[0061] Based on the above detailed description of several exemplary embodiments of the heat exchange structure 100 proposed in the present invention, an exemplary embodiment of the battery device proposed in the present invention will be described below.

[0062] See also Figure 8 , Figure 81 represents a three-dimensional exploded schematic diagram of a battery device that can embody the principle of the present invention, in which the encapsulation layer 140 is separated from the heat exchange structure 100 from a top view. The battery device proposed in the present invention is described by taking a vehicle-mounted battery as an example. It is easy for those skilled in the art to understand that in order to apply the relevant design of the present invention to other types of battery devices, various modifications, additions, substitutions, deletions or other changes are made to the specific embodiments described below, and these changes are still within the scope of the principle of the battery device proposed in the present invention.

[0063] like Figure 8 As shown, in one embodiment of the present invention, the battery device proposed by the present invention includes a box 200, a battery (not shown in the drawings), and a heat exchange structure 100 proposed by the present invention and described in detail in the above embodiments. Specifically, the battery is disposed in the box 200, and the heat exchange structure 100 is disposed in the box 200 and is used to exchange heat with the battery. For example, Figure 8 The illustrated embodiment is described by taking the heat exchange structure 100 disposed at the bottom of the battery as an example. In some embodiments, the heat exchange structure 100 may also be disposed at the top or side of the battery, which is not limited to this embodiment.

[0064] like Figure 8 As shown, in one embodiment of the present invention, the box 200 may have a mounting point 210, and the mounting point 210 may be used for mounting the battery device. On this basis, the protective plate 130 of the heat exchange structure 100 may have a reinforcement portion 131, and the position of the reinforcement portion 131 is arranged corresponding to the position of the mounting point 210. Through the above structural design, since the mounting point 210 is the connection between the battery device and the whole vehicle, that is, it is a weak point of the battery device, and the mounting point 210 protrudes from the box 200 and is more susceptible to external impact, when the mounting point 210 is impacted, the position of the box 200 corresponding to the mounting point 210 is prone to deformation, and the part of the heat exchange structure 100 corresponding to the above position will also be deformed accordingly. Accordingly, the present invention can improve the structural strength of the corresponding position of the protective plate 130 through the above reinforcement portion 131, so that the corresponding position of the protective plate 130 is not easy to deform, and the protective effect is further ensured.

[0065] like Figure 8As shown, based on the structural design that the box body 200 has the mounting point 210 and the protective plate 130 has the reinforcement part 131, in one embodiment of the present invention, the plane where the second surface 1201 of the honeycomb panel 120 is located is used as the reference plane, on which the orthographic projection of the reinforcement part 131 can be in the shape of a long strip extending along a straight path, and the orthographic projection of the mounting point 210 can be located on the extension line L of the straight path. Through the above structural design, the present invention can further ensure the positional correspondence between the reinforcement part 131 and the mounting point 210, so as to use the reinforcement part 131 to provide a structural reinforcement function for the corresponding position of the protective plate 130 in a more targeted manner.

[0066] like Fig. 9 As shown, Fig. 9 The cross-sectional structure of the heat exchange structure 100 at the reinforcement part 131 is representatively shown in FIG. Based on the structural design that the box body 200 has the mounting point 210 and the protective plate 130 has the reinforcement part 131, in one embodiment of the utility model, the reinforcement part 131 can be a boss formed by the integral bending of the protective plate 130, and the boss can protrude toward the honeycomb panel 120. In other words, when observed from the third surface 1301 of the protective plate 130, the reinforcement part 131 can be a groove-shaped structure. Through the above structural design, the utility model can simplify the processing technology of the boss on the basis of ensuring that the protective plate 130 forms a boss, while ensuring the flatness of the third surface 1301, thereby reducing the packaging difficulty of the packaging layer 140 and avoiding damage to the packaging layer 140 at the reinforcement part 131. Furthermore, the position of the honeycomb panel 120 corresponding to the boss may have a depression of matching shape, so that the boss extends into the depression and ensures the fit with the heat exchange plate 110, thereby further increasing the contact area between the protective plate 130 and the honeycomb panel 120 and improving the support strength. In some embodiments, when the reinforcing portion 131 is a boss, the boss may also protrude away from the honeycomb panel 120. In other words, when observed from the third surface 1301 of the protective plate 130, the reinforcing portion 131 may be a convex rib-like structure. In addition, the reinforcing portion 131 is not limited to the formation method of integrally bending the protective plate 130. The reinforcing portion 131 may also be separately provided on the protective plate 130, and the connection method between the reinforcing portion 131 and the protective plate 130 may be, for example, integrally formed, welded, or connected with a connector, etc., which are not limited to the present embodiment.

[0067] It should be noted that the battery devices shown in the drawings and described in this specification are only a few examples of many battery devices that can adopt the principles of the present invention. It should be clearly understood that the principles of the present invention are by no means limited to any details of the battery devices shown in the drawings or described in this specification or any components of the battery devices.

[0068] In summary, the battery device proposed in the present invention, by adopting the heat exchange structure 100 proposed in the present invention, can make the heat exchange structure 100 have better anti-ball impact ability, and at the same time can ensure the buffering effect of the honeycomb panel 120 and the heat exchange effect of the heat exchange plate 110.
