Along the first direction, the thickness dimension of the first metal layer is set to D1, and the thickness dimension of the second metal layer is set to D2. The thickness D1 and the thickness D2 satisfy: D1>D2.

The heating module includes a heating layer, a first metal layer, and a second metal layer. The heating layer is configured to convert electrical energy into thermal energy. The heating layer has a first wall surface and a second wall surface that are arranged relatively along its own thickness direction. The first metal layer abuts the first wall surface. The second metal layer abuts the second wall surface. The heat of the heating layer is guided to each single-cell battery through the first metal layer.

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiment is only a component embodiment of the present application, rather than an embodiment of the entire component. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship and movement status of the components under a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0055] In addition, when an element is said to be "fixed to" another element, it can be directly on the other element, or one or more intervening elements can exist between them. When an element is said to be "connected to" another element, it can be directly connected to the other element, or one or more intervening elements can exist between them.

[0056] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0057] In the prior art, the heating assembly includes a heating layer and a heat-conducting layer, and the battery is arranged on the side of the heat-conducting layer away from the heating layer. The heat generated by the heating layer will be conducted in the direction away from the heat-conducting layer, causing the heat generated by the heating layer to be lost, thereby reducing the drying rate of each battery. In addition, due to the uneven distribution of the heat source of the heating layer, the heat acting on the battery through the heat-conducting layer is unevenly distributed, so that the drying rates of batteries at different positions of the heat-conducting layer are different, thereby reducing the drying rate of each battery.

[0058] To solve the above problems, see Figures 1 to 8 The present application proposes a heating module 10. The heating module 10 is used for a carrier 20. The carrier 20 is used to load multiple single batteries 30. The heating module 10 includes a heating layer 100, a first metal layer 200, and a second metal layer 300. The number of single batteries 30 loaded on the carrier 20 can be determined according to actual conditions. For example, the number of single batteries 30 loaded on the carrier 20 can be two, three, four, five, etc. The heating module 10 is used to dry the multiple single batteries 30 loaded on the carrier 20 to process the single batteries 30.

[0059] The heating layer 100 is configured to convert electrical energy into thermal energy, and the heating layer 100 is also configured to provide thermal energy to the first metal layer 200. The outer contour of the heating layer 100 can be in a variety of structures. In some embodiments, the heating layer 100 can be a rectangular parallelepiped. In other embodiments, the heating layer 100 can be a cylindrical body. In other embodiments, the heating layer 100 can be a polygon, etc., depending on the actual situation. The embodiment of the present application takes the rectangular parallelepiped heating layer 100 as an example. The heating layer 100 has a first wall 110 and a second wall 120 arranged relatively along its thickness direction. The outer contours of the first wall 110 and the second wall 120 can be in a variety of structures, depending on the actual situation. The embodiment of the present application takes the first wall 110 of the plane wall and the second wall 120 of the plane wall as an example. In some embodiments, the first wall 110 is perpendicular to the first direction X. In other embodiments, the second wall 120 is perpendicular to the first direction X. Furthermore, the first wall surface 110 and the second wall surface 120 are parallel to each other, and the first wall surface 110 is perpendicular to the first direction X.

[0060] The first metal layer 200 abuts against the first wall 110. The outer contour of the first metal layer 200 can be in a variety of structures. In some embodiments, the first metal layer 200 can be in a rectangular parallelepiped. In other embodiments, the first metal layer 200 can be in a cylindrical shape. In other embodiments, the first metal layer 200 can be in a polygonal shape, etc., depending on the actual situation. The embodiment of the present application takes the rectangular first metal layer 200 as an example. In some embodiments, the first metal layer 200 is connected to the heating layer 100. Furthermore, the first metal layer 200 and the heating layer 100 are connected by welding.

[0061] The second metal layer 300 abuts against the second wall 120. The outer contour of the second metal layer 300 can be in a variety of structures. In some embodiments, the second metal layer 300 can be in the form of a rectangular parallelepiped. In other embodiments, the second metal layer 300 can be in the form of a cylinder. In other embodiments, the second metal layer 300 can be in the form of a polygon, etc., depending on the actual situation. The embodiment of the present application takes the rectangular second metal layer 300 as an example. In some embodiments, the second metal layer 300 is connected to the heating layer 100. Further, the second metal layer 300 is connected to the heating layer 100 by welding. It should be noted that in some embodiments, the length dimension of the second metal layer 300 is the same as the length dimension of the first metal layer 200. In other embodiments, the width dimension of the second metal layer 300 is the same as the width dimension of the first metal layer 200.

[0062] The first direction X is set as the direction from the first metal layer 200 to the second metal layer 300, and the heat of the heating layer 100 is directed to the battery 30 of each unit through the first metal layer 200. Figures 2 to 7. In the present application, the second metal layer 300 is disposed on the side of the heating layer 100 away from the first metal layer 200 along the first direction X. When the heat of the heating layer 100 is directed to the batteries 30 of each monomer through the first metal layer 200, the heat generated by the heating layer 100 along the direction away from the first metal layer 200, that is, along the first direction X, is insulated by the second metal layer 300, thereby preventing heat loss, improving the efficiency of using the heat generated by the heating layer 100, and improving the working efficiency of the heating module 10 in drying the batteries 30. In some embodiments, the heat of the heating layer 100 diffuses in the first metal layer 200 in the opposite direction of the first direction X. Along the first direction X, the thickness dimension of the first metal layer 200 is set to D1, and the thickness dimension of the second metal layer 300 is set to D2. The thickness D1 and the thickness D2 satisfy: D1>D2, see Figure 3 . It should be noted that the thickness D1 and the thickness D2 can be in a variety of relationships. For example, the thickness D1 and the thickness D2 can satisfy D1=1.2D2, D1=1.5D2, D1=2D2, D1=2.5D2, D1=3D2, etc. In the present application, by making the thickness dimension D1 of the first metal layer 200 and the thickness dimension D2 of the second metal layer 300 satisfy: D1>D2, the thickness of the first metal layer 200 is increased, so that the heating layer 100 can be completely diffused in the first metal layer 200, so that the heat can be evenly conducted to the battery 30, the drying efficiency of the battery 30 is improved, and the working efficiency of the heating module 10 is improved. It should be noted that the thickness dimension of the first metal layer 200 is set to D1, and different parts of the first metal layer 200 are measured multiple times along the first direction X to obtain multiple thickness dimensions, and the average value of each thickness dimension is taken to obtain the thickness dimension D1. It should be noted that the thickness dimension of the second metal layer 300 is set as D2. Different parts of the second metal layer 300 are measured multiple times along the first direction X to obtain multiple thickness dimensions, and the average value of each thickness dimension is taken to obtain the thickness dimension D2.

[0063] In some embodiments, the thickness D1 and the thickness D2 satisfy: D1 ≥ 1.5D2. It should be noted that the thickness D1 and the thickness D2 can be in a variety of relationships. For example, the thickness D1 and the thickness D2 can satisfy D1 = 1.5D2, D1 = 2D2, D1 = 2.5D2, D1 = 3D2, etc. It should be noted that the thickness D1 of the first metal layer 200 should be moderate.

[0064] The materials of the first metal layer 200 and the second metal layer 300 are both metal materials with good thermal conductivity. Exemplarily, the material of the first metal layer 200 can be aluminum alloy, metal aluminum, iron alloy, metal iron, etc., and the material of the second metal layer 300 can also be aluminum alloy, metal aluminum, iron alloy, metal iron, etc. In some embodiments, the material of the first metal layer 200 is the same as that of the second metal layer 300, and the material of the first metal layer 200 and the second metal layer 300 is metal aluminum.

[0065] The first projection plane is set to be a plane perpendicular to the first direction X, see Figure 7 , the heating layer 100 forms a first orthographic projection on the first projection plane, the first metal layer 200 forms a second orthographic projection on the first projection plane, and the first orthographic projection coincides with the second orthographic projection. That is, the first metal layer 200 includes a fifth wall surface, the fifth wall surface is configured to abut the first wall surface 110, and the fifth wall surface is attached to the first wall surface 110, so that the wall surface attached to the heating layer 100 and the first metal layer 200 forms a larger orthographic projection area on the first projection plane, thereby increasing the area of ​​heat transfer between the heating layer 100 and the first metal layer 200, and increasing the rate of heat transfer between the heating layer 100 and the first metal layer 200. Moreover, when the heat generated by the heating layer 100 remains unchanged, the area of ​​heat transfer between the heating layer 100 and the first metal layer 200 is increased, so as to further increase the diffusion rate of the heating layer 100 in the first metal layer 200, so that the heat can be evenly conducted to the battery 30, further improving the drying efficiency of the battery 30, and further improving the working efficiency of the heating module 10. Furthermore, the area of ​​the second orthographic projection is larger than the area of ​​the first orthographic projection. Since the heating layer 100 includes a central area and surrounding areas, and the rate of heat conduction caused by the surrounding areas contacting the outside world is greater than the rate of heat conduction caused by the central area through the surrounding areas, the rate of heat loss in the surrounding areas is greater than the rate of heat loss in the central area. By making the area of ​​the second orthographic projection larger than the area of ​​the first orthographic projection, the volume of the central area is expanded, so that the heat is concentrated in the central area. When the heat generated by the heating layer 100 remains unchanged, the rate of drying the batteries 30 is further improved, and the working efficiency of the heating module 10 is further improved.

[0066] The second metal layer 300 forms a third orthographic projection on the first projection plane, and the first orthographic projection overlaps with the third orthographic projection. That is, the second metal layer 300 includes a sixth wall surface, and the sixth wall surface is configured to abut the second wall surface 120, and the sixth wall surface is attached to the second wall surface 120, so that the wall surface attached to the heating layer 100 and the second metal layer 300 forms a larger orthographic projection area on the first projection plane, thereby increasing the area of ​​heat transfer between the heating layer 100 and the second metal layer 300, and the area of ​​the insulation effect provided by the second metal layer 300 to the heating layer 100, further improving the use efficiency of the heat generated by the heating layer 100, and further improving the working efficiency of the heating module 10 in drying the battery 30. Furthermore, the area of ​​the third orthographic projection is larger than the area of ​​the first orthographic projection. Since the heating layer 100 includes a central area and surrounding areas, and the rate of heat conduction caused by the surrounding areas contacting the outside world is greater than the rate of heat conduction caused by the central area through the surrounding areas, the rate of heat loss in the surrounding areas is greater than the rate of heat loss in the central area. The area of ​​the third orthographic projection is larger than the area of ​​the first orthographic projection to expand the volume of the central area so that the heat is concentrated in the central area, and the heat generated by the heating layer 100 is further enhanced. The insulation effect of the second metal layer 300 is further enhanced to prevent heat loss, further improve the utilization efficiency of the heat generated by the heating layer 100, and further improve the working efficiency of the heating module 10 in drying the battery 30.

[0067] The heating layer 100 includes a first peripheral wall 130, see Figure 4 as well as Figure 5In some embodiments, the first peripheral wall 130 includes four walls perpendicular to the first wall 110. The first peripheral wall 130 is disposed between the first wall 110 and the second wall 120, the second metal layer 300 includes a working groove 310 and a third wall 320, the working groove 310 is disposed on the third wall 320, and the length direction of the working groove 310 is perpendicular to the first direction X. In some embodiments, the third wall 320 is perpendicular to the first direction X. The working groove 310 includes a second peripheral wall 311 and a fourth wall 312. In some embodiments, the second peripheral wall 311 includes four walls perpendicular to the first wall 110. In other embodiments, the fourth wall 312 is perpendicular to the first direction X. The fourth wall 312 abuts against the second wall 120, the second peripheral wall 311 is disposed between the third wall 320 and the fourth wall 312, and the heating layer 100 is configured to be disposed in the working groove 310, and the first peripheral wall 130 abuts against the second peripheral wall 311. The first peripheral wall 130 is in contact with the second peripheral wall 311, so that when the heat of the heating layer 100 is directed to each single battery 30 through the first metal layer 200, the heat generated by the heating layer 100 is dissipated outward through the first peripheral wall 130. The heat is isolated by the second peripheral wall 311 of the second metal layer 300, thereby further preventing the heat generated by the heating layer 100 from being dissipated, further improving the utilization efficiency of the heat generated by the heating layer 100, and further improving the working efficiency of the heating module 10 in drying the battery 30.

[0068] See also Figure 4, the thickness dimension of the working groove 310 is set to D3, the thickness dimension of the heating layer 100 is set to D4, and the thickness D3 and the thickness D4 satisfy: D3<D4, so that when the heat generated by the heating layer 100 is dissipated outward through the first peripheral wall 130, the heat insulation effect of the second peripheral wall 311 of the second metal layer 300 is further improved, and the heat generated by the heating layer 100 is further prevented from being lost, and the working efficiency of the heating module 10 in drying the battery 30 is further improved. It should be noted that the thickness D3 and the thickness D4 can be in a variety of relationships. For example, the thickness D3 and the thickness D4 can satisfy D4=1.2D3, D4=1.5D3, D4=2D3, D4=2.5D3, D4=3D3, etc. It should be noted that the thickness dimension of the working groove 310 is set to D3, and multiple measurements are performed on different parts of the working groove 310 along the first direction X to obtain multiple thickness dimensions, and the average value of each thickness dimension is taken to obtain the thickness dimension D3. It should be noted that the thickness dimension of the heating layer 100 is set to D4, and different parts of the heating layer 100 are measured multiple times along the first direction X to obtain multiple thickness dimensions, and the thickness dimensions are averaged to obtain the thickness dimension D4. In some embodiments, the second projection plane is set to a plane parallel to the first direction X, the first peripheral wall 130 forms a fourth orthographic projection on the second projection plane, and the second peripheral wall 311 forms a fifth orthographic projection on the second projection plane, and the third projection plane is set to a plane parallel to the first direction X and perpendicular to the second projection plane, the first peripheral wall 130 forms a sixth orthographic projection on the third projection plane, and the second peripheral wall 311 forms a seventh orthographic projection on the second projection plane, the fourth orthographic projection coincides with the fifth orthographic projection, and the sixth orthographic projection coincides with the seventh orthographic projection, so that the area of ​​the first peripheral wall 130 and the second peripheral wall 311 is larger, further improving the use efficiency of the heat generated by the heating layer 100, and further improving the working efficiency of the heating module 10 in drying the battery 30.

[0069] The heating layer 100 includes an energy harvesting device 140, see Figure 6 . In some embodiments, the energy harvesting device 140 includes a power interface. In other embodiments, the energy harvesting device 140 includes a contact pin. The energy harvesting device 140 is configured to obtain electrical energy to provide electrical energy to the heating layer 100 for conversion into thermal energy, and the energy harvesting device 140 is located on the second wall 120. The second metal layer 300 includes a working through hole 330, the direction of the axis of the working through hole 330 intersects with the first direction X, and the working through hole 330 is used to place the energy harvesting device 140. In some embodiments, the direction of the axis of the working through hole 330 is co-directional with the first direction X.

[0070] The second aspect of the present application also provides a carrier 20, see Figure 1 as well as Figure 8The carrier 20 includes any one of the heating modules 10 and the housing 40 of the above embodiments.
