[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the scope of protection of the present utility model.

[0022] The embodiments of the present utility model provide a heat conducting device to solve the problem of potential safety hazards caused by overheating of electrical devices due to large current in the prior art. Refer to Figure 1 and Figure 3, including the body 6 to be cooled, further including a heat conducting plate 1. One side of the heat conducting plate 1 is fixedly connected to the body 6 to be cooled through a connecting component 7; the other side of the heat conducting plate 1 is connected to a heat insulating body 2, and a cooling device 4 is arranged on the heat insulating body 2; the heat conducting plate 1 is used to fix and conduct heat for the body 6 to be cooled. Heat is transferred from the heat conducting plate 1 to the heat insulating body 2 and then neutralized with the cooling device 4 to dissipate heat from the body 6 to be cooled.

[0023] In one embodiment, a groove 8 is formed in the heat insulating body 2, and the other side of the heat conducting plate 1 is located in the groove 8. The heat conducting plate 1 is connected to the groove 8 through a heat conducting medium; by placing one end of the heat conducting plate 1 in the groove 8, different length positions of the heat conducting plate 1 can be placed in the groove 8 according to the length requirement of the heat conducting plate 1, and then the heat conducting plate 1 is fixed to the heat insulating body 2 through the heat conducting medium, so that different heights can be presented after the heat conducting plate 1 is connected to the heat insulating body 2. Thus, according to the size of the internal space during the assembly process, the heat conducting plate 1 can be connected to the body 6 to be cooled at different positions, improving the application range of the heat conducting device and absorbing assembly errors.

[0024] In one embodiment, the heat conducting medium is heat conducting glue; the heat conducting glue has good heat conduction and electrical insulation properties, and the heat conducting glue has adhesive properties with high bonding strength, which can realize the stable connection between the heat conducting plate 1 and the heat insulating body 2; after the heat conducting glue is cured, it becomes an elastomer, having the effects of shock resistance and vibration resistance, and having good heat conduction and heat dissipation functions.

[0025] A bracket 3 is arranged between the heat insulating body 2 and the cooling device 4. The bracket 3 fixes the heat insulating body 2, and the bracket 3 and the cooling device 4 are fixedly connected through a heat conducting buffer zone 5; the heat insulating body 2 is fixed by the bracket 3, and the heat conducting buffer zone 5 also has a certain buffering effect to further protect the body 6 to be cooled, ensure the stability of the heat insulating body 2 during the heat conduction process, and then dissipate heat through the cooling device 4.

[0026] The heat conducting buffer zone 5 is heat conducting structural glue; the lower end of the heat insulating body 2 is adhered to the surface of the cooling device 4 through the heat conducting structural glue, and the thickness of the heat conducting structural glue can be adjusted adaptively. The heat conducting structural glue plays the roles of fixing between the bracket 3 and the cooling device 4, as well as heat transfer and absorbing assembly tolerances.

[0027] The heat conducting plate 1 is of an L-shaped structure; the L-shaped heat conducting plate 1 can connect one side of the heat conducting plate 1 to the body 6 to be cooled, and the other side of the heat conducting plate 1 contacts the heat insulating body 2 for heat conduction and fixing, which is convenient for fixing and conducting heat for the body 6 to be cooled.

[0028] The different height positions of the second side of the heat conduction plate 1 are connected to the heat conduction insulator 2; by adjusting the length of the vertical side of the heat conduction plate 1 fixed to the heat conduction insulator 2, the height of the heat conduction plate 1 above the heat conduction insulator 2 can be adjusted, so as to meet the requirements of different usage environments and improve the scope of use.

[0029] The connecting component 7 is a bolt; the heat conduction plate 1 and the body 6 to be cooled are fixed by bolts, which is convenient for installation operation and can be disassembled conveniently.

[0030] The heat conduction insulator 2 is a heat conduction ceramic, refer to Figure 2 , the bracket 3 includes a bottom plate 31, a fixing block 32 and an adjusting strip 33, and the adjusting strip 33 has elasticity; the heat conduction insulator 2 is preferably a heat conduction ceramic. The heat conduction ceramic can not only achieve the heat conduction effect but also is a high-insulation material. The heat conduction ceramic has high hardness, good wear resistance and light weight. By using the heat conduction ceramic, the insulation and voltage resistance problems in a humid environment can be solved; the bottom of the bracket 3 is hollowed out. Fixing blocks 32 are fixedly arranged on the opposite sides of the upper end of the bracket 3, and adjusting strips 33 are fixedly arranged on the other two sides of the upper end of the bracket 3. The adjusting strip 33 has elasticity. The whole bracket 3 can be integrally formed by plastic; when the heat conduction insulator 2 needs to be fixed, an external force is applied to the adjusting strip 33 on both sides from the upper end of the bracket 3 to make the adjusting strip 33 deformed. After the heat conduction insulator 2 is placed on the bottom plate 31 of the bracket 3, the adjusting strip 33 is released, and the adjusting strip 33 returns to its original state and fits the side surface of the heat conduction insulator 2 and the upper end is stuck on the top of the heat conduction insulator 2. The heat conduction insulator 2 is fixed by the fixing block 32 and the adjusting strip 33 to ensure the stability of the heat conduction insulator 2 during the working process.

[0031] In a specific implementation, the body 6 to be cooled is connected to the first side ( Figure 1 the horizontal side in Figure 1Insert the vertical edge of the heat conduction plate 1 into the groove 8 of the heat conduction insulator 2. The heat conduction insulator 2 is preferably a heat conduction ceramic. The heat conduction ceramic can not only achieve the heat conduction effect but also is a high-insulation material. The heat conduction ceramic has high hardness, good wear resistance and light weight. According to the different height positions of the body 6 to be cooled and the different internal spaces of the installation position, adjust the length of the vertical edge of the heat conduction plate 1 fixed in the groove 8 to adapt to different internal spaces and different positions of the body 6 to be cooled. Then, pour heat conduction glue into the groove 8, and fix the corresponding position of the heat conduction plate 1 in the groove 8 through the solidification of the heat conduction glue. When pouring the heat conduction glue, the groove 8 cannot be filled completely, so that the top of the groove 8 is used to collect a very small amount of condensed water to prevent the condensed water from flowing down, resulting in a decrease in insulation withstand voltage. Then, fix the heat conduction insulator 2 through the bracket 3 to restrain the heat conduction insulator 2 (it is also possible to fix the heat conduction plate 1 and the body 6 to be cooled after fixing the heat conduction insulator 2 through the bracket 3 first). Then, bond the lower end of the heat conduction insulator 2 to the surface of the cooling device 4 through heat conduction structural glue. During the heat conduction process, the heat conduction plate 1 conducts the heat of the body 6 to be cooled to the heat conduction insulator 2, and then the cooling device 4 neutralizes the heat to achieve the heat dissipation of the body 6 to be cooled.

[0032] The utility model solves the problems of insulation withstand voltage under high voltage in the battery system and overheating of devices under excessive current through the cooperation of the heat conduction plate 1, the heat conduction ceramic and the cooling device 4, and is easy to install and has generalization.

[0033] In an embodiment, the heat conduction medium is a heat conduction pad. First, put the vertical edge of the heat conduction plate 1 into the groove 8. According to the required length of the heat conduction plate 1, put the part of the vertical edge of the heat conduction plate 1 corresponding to the length into the groove 8, and then arrange the heat conduction pad on the inner wall of the groove 8. The heat conduction plate 1 is surrounded and extruded by the heat conduction pad to realize the fixation of the heat conduction plate 1. The heat conduction pad conducts heat while fixing the heat conduction plate 1.
