Description

Technical Field

[0001] This utility model relates to the field of automotive battery technology, specifically to a high thermal conductivity aluminum alloy plate for automotive batteries. Background Technology

[0002] A car battery box is a box-shaped or frame structure that houses a car battery. It is used to protect the battery and provide a mounting location. The car battery is an important part of the vehicle's electrical system, providing electrical energy to start the engine and power electrical equipment.

[0003] Among them, an automotive battery box with announcement number CN209232857U includes a holding box, airbags are fixedly installed around the holding box, partitions are evenly installed inside the holding box, helical springs are evenly installed on the left and right sides of the partitions, a sliding rod is sleeved inside the helical spring, a top block is fixedly installed at the outer end of the sliding rod, a temperature sensing sheet is fixedly installed on the outer side of the top block, and a display screen is fixedly installed on the surface of the top block.

[0004] However, most existing aluminum alloy plates are single-layer flat structures, which only transfer the heat of the battery to the outside through the heat conduction of the plate itself. They lack structural designs to enhance heat conduction and heat dissipation. When the battery is fast charging or discharging under high load, the heat generated per unit time is high. The single-layer aluminum alloy plate cannot quickly dissipate the heat, resulting in excessively high local temperature of the battery, which affects the battery's service life. Utility Model Content

[0005] In view of the problems existing in the current automotive batteries, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a high thermal conductivity aluminum alloy plate for automotive batteries, which solves the problem that most existing aluminum alloy plates are single-layer flat structures that only transfer battery heat to the outside through the heat conduction of the plate itself, lacking a structure to enhance heat conduction and heat dissipation. When the battery is fast charging or discharging under high load, the heat generated per unit time is high, and the single-layer aluminum alloy plate cannot quickly dissipate the heat, resulting in excessively high local temperature of the battery, thus affecting the battery's service life.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high thermal conductivity automotive battery aluminum alloy plate includes an aluminum alloy substrate, a heat conduction platform, and a battery carrier plate. The heat conduction platform is fixedly connected to one side of the aluminum alloy substrate and has a honeycomb-like interior. The battery carrier plate is fixedly connected to one side of the heat conduction platform. A protective plate is fixedly connected around the battery carrier plate and the aluminum alloy substrate. A filling cavity is provided between the protective plate and the heat conduction platform, and a filling layer is provided inside the filling cavity.

[0009] Preferably, one side of the aluminum alloy substrate is fixedly connected to a heat dissipation fin assembly, the heat dissipation fin assembly including horizontal fins and vertical fins, the horizontal fins and vertical fins being vertically and intersecting to form a grid-like heat dissipation channel.

[0010] Preferably, the filling layer is a thermally conductive silicone pad.

[0011] Preferably, the battery carrier plate has multiple mounting holes on one side, and each mounting hole has an internal thread.

[0012] Preferably, the heat-conducting stage is circular in shape, and the honeycomb holes of the heat-conducting stage have a regular hexagonal structure.

[0013] Preferably, the edges and corners of the aluminum alloy substrate, battery carrier plate, and protective plate are all chamfered.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. In this utility model, the heat generated by the battery during operation is first transferred to the honeycomb heat conduction platform through the battery carrier plate. The heat is quickly dispersed along the hole wall and conducted to the aluminum alloy substrate. The thermally conductive silicone pad of the filling layer can fill the gap between the heat conduction platform and the protective plate, reduce thermal resistance, and assist in heat conduction. Finally, the heat is transferred to the grid-shaped heat dissipation fin assembly through the aluminum alloy substrate. The turbulent channels formed by the fins accelerate the exchange of heat with the outside air. Compared with the traditional single-layer aluminum alloy plate, the overall thermal conductivity is improved.

[0016] 2. The protective plate forms a closed structure that can resist the intrusion of dust and moisture during vehicle operation. At the same time, the thermally conductive silicone pad in the filling layer is elastic and can absorb the vibration and impact generated by vehicle bumps, thereby improving the battery's service life.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a high thermal conductivity aluminum alloy plate for automotive batteries.

[0025] This utility model provides, for example Figure 1-3 The high thermal conductivity automotive battery aluminum alloy plate shown includes an aluminum alloy substrate 1, a heat conduction platform 2, and a battery support plate 3. The heat conduction platform 2 is fixedly connected to one side of the aluminum alloy substrate 1, and the interior of the heat conduction platform 2 is honeycomb-shaped. The battery support plate 3 is fixedly connected to one side of the heat conduction platform 2. A protective plate 4 is fixedly connected around the battery support plate 3 and the aluminum alloy substrate 1. A filling cavity is provided between the protective plate 4 and the heat conduction platform 2. A filling layer 5 is provided inside the filling cavity. Multiple mounting holes are opened on one side of the battery support plate 3, and each mounting hole has an internal thread.

[0026] The car battery is stably installed through the mounting holes on the battery carrier plate 3. The heat generated when the battery is working is transferred to the surface of the heat conduction platform 2 through the carrier plate 3 and dispersed to prevent heat from accumulating locally on the surface of the battery.

[0027] like Figure 1-2 As shown, one side of the aluminum alloy substrate 1 is fixedly connected to a heat dissipation fin assembly 6, which includes horizontal fins and vertical fins. The horizontal fins and vertical fins are vertically intersected and connected to form a grid-like heat dissipation channel.

[0028] The heat transferred from the aluminum alloy substrate 1 is transferred to the fins through thermal conduction. The fins come into contact with the outside air and release the heat into the air through natural convection. The mesh-like channels can guide the air to form turbulence between the fins, which improves the heat dissipation efficiency compared to traditional parallel fins.

[0029] like Figure 2 As shown, the filling layer 5 is a thermally conductive silicone pad.

[0030] A thermally conductive silicone pad is installed inside the filling cavity between the protective plate 4 and the heat conduction platform 2. While playing an auxiliary role in heat conduction, it can also play a role in buffering and shock absorption, and can absorb the vibration and impact during vehicle operation.

[0031] like Figure 1-2As shown, the heat-conducting stage 2 is circular in shape, and the honeycomb holes of the heat-conducting stage 2 have a regular hexagonal structure.

[0032] The interior of the heat conduction stage 2 has a regular hexagonal honeycomb structure. The regular hexagonal honeycomb structure has the characteristics of large surface area and structural stability. On the one hand, it can increase the contact area between the heat conduction stage and the support plate 3 and the aluminum alloy substrate 1, and accelerate the heat transfer from the support plate 3 to the aluminum alloy substrate 1. On the other hand, the walls of the honeycomb holes can form dense heat conduction channels, and heat is quickly conducted along the hole walls, thereby improving the heat conduction efficiency.

[0033] like Figure 1-3 As shown, the aluminum alloy substrate 1, the battery carrier plate 3, and the protective plate 4 all have chamfered edges.

[0034] The aluminum alloy substrate 1, the support plate 3, and the protective plate 4 all have chamfered edges. On the one hand, this can prevent workers from being scratched by sharp edges during installation, thus improving operational safety. On the other hand, it can adapt to the internal space of the car battery box, avoiding structural damage caused by collisions between the edges and the inner wall of the box, thus improving the overall adaptability of the device.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
