Description

Technical Field

[0001] This utility model belongs to the field of battery equipment, and specifically relates to a square power battery module with a graphdiyne thermal conductive layer. Background Technology

[0002] Square power battery modules are core components commonly used in energy storage devices and other fields, primarily for storing and providing electrical energy. Currently, square power battery modules suffer from insufficient heat dissipation. During charging and discharging, the internal chemical reactions of the cells release a significant amount of heat. The square structure results in a relatively long path for heat conduction from the cells to the module casing, and the tightly packed cells further hinder rapid heat dissipation. Heat easily accumulates inside the module, forming localized high-temperature areas that affect battery performance and lifespan. To address this, a common approach is to add traditional thermally conductive materials between the cells, relying solely on these materials in conjunction with the external casing for heat conduction, such as thermally conductive silicone pads. However, these materials have limited thermal conductivity and cannot dissipate heat as quickly as ideal materials. Increasing the thickness of the thermally conductive material can improve heat conduction to some extent, but it occupies more internal space within the casing, leading to a decrease in the battery module's energy density. Therefore, a new structure is needed to solve the aforementioned technical problems. Utility Model Content

The shell assembly includes a shell body for mounting the battery assembly, the battery assembly includes a battery cell for power supply, and the heat dissipation assembly includes a heat sink and a cooling fan. The cooling fan is installed on the surface of the heat sink.

[0005] In a preferred embodiment, a convex shell is integrally formed on the upper surface of the outer casing, and a power interface is provided on the upper surface of the convex shell. The power interface is electrically connected to the battery assembly. A battery cell is installed inside the outer casing, and a fixing bracket is installed on the outer surface of the battery cell.

[0006] In a preferred embodiment, the outer shell body is made of aluminum alloy, and an insulating layer is installed on the inner wall surface of the outer shell body. The insulating layer is made of ceramic, and the structure of the insulating layer matches the structure of the inner wall of the outer shell body.

[0007] In a preferred embodiment, a graphyne layer is integrally formed on the left, right, front, and rear surfaces of the battery cell. The inner surface of the graphyne layer is connected to the outer surface of the battery cell, and the side of the graphyne layer away from the battery cell is connected to the inner surface of the insulating layer. In use, in a square power battery module with a graphyne thermal conductive layer, the graphyne layer integrally formed on all four sides of the battery cell, with its ultra-high thermal conductivity, can quickly conduct the heat of the battery cell to the outer casing, reducing interfacial thermal resistance. Combined with the heat dissipation components on the outer surface of the outer casing, this effectively extends the battery life and ensures stable operation of the device.

[0010] In a preferred embodiment, the surface of the heat sink away from the cooling fan is connected to the outer surface of the outer casing. Thermal grease is applied at the connection between the heat sink and the outer casing. The heat dissipation assembly is electrically connected to the internal battery cell assembly via wires. In use, the heat dissipation assembly is installed in the square power battery module with the graphdiyne thermal conductive layer. This fully utilizes the high thermal conductivity of the graphdiyne layer. The heat sink is tightly attached to the battery module casing, quickly absorbing the heat conducted by the graphdiyne layer and expanding the heat dissipation area. Then, the cooling fan is used to force convection and accelerate airflow, rapidly dissipating the heat and effectively reducing the operating temperature of the battery module, thus ensuring the stable operation of the new energy equipment.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting up a shell assembly, a battery assembly for providing power is installed inside the shell assembly. The shell assembly includes a shell body for installing the battery assembly. An insulating layer is installed on the inner wall surface of the shell body. The left, right, front, and rear surfaces of the battery cell are integrally formed with a graphdiyne layer. In use, in the square power battery module with a graphdiyne thermal conductive layer, the graphdiyne layer integrally formed on all four sides of the battery cell can quickly conduct the heat of the battery cell to the shell body with ultra-high thermal conductivity, reducing the interface thermal resistance. Combined with the heat dissipation components on the outer surface of the shell body, it effectively extends the battery life and ensures stable operation of the equipment.

[0012] By setting up a heat dissipation component, a heat dissipation component for cooling the battery module is installed on the outer surface of the outer casing component.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3As the first embodiment of this utility model: a square power battery module with a graphdiyne thermal conductive layer, including: a shell assembly, a battery assembly and a heat dissipation assembly. The battery assembly for providing power is installed inside the shell assembly, and a heat dissipation assembly for dissipating heat from the battery assembly is installed on the outer surface of the shell assembly. The shell assembly includes a shell body 100 for installing the battery assembly, the battery assembly includes a cell 210 for providing power, and the heat dissipation assembly includes a heat dissipation plate 300 and a heat dissipation fan 320. The heat dissipation fan 320 is installed on the surface of the heat dissipation plate 300.

[0022] A convex shell 110 is integrally formed on the upper surface of the outer shell 100. A power interface 120 is provided on the upper surface of the convex shell 110. The power interface 120 is electrically connected to the battery assembly. A battery cell 210 is installed inside the outer shell 100. A fixing bracket 230 is installed on the outer surface of the battery cell.

[0023] The outer shell 100 is made of aluminum alloy, and an insulating layer 200 is installed on the inner wall surface of the outer shell 100. The insulating layer 200 is made of ceramic, and the structure of the insulating layer 200 matches the structure of the inner wall of the outer shell 100.

[0024] A graphdiyne layer 220 is integrally formed on the left, right, front, and rear surfaces of the battery cell 210. The inner surface of the graphdiyne layer 220 is connected to the outer surface of the battery cell, and the side of the graphdiyne layer 220 away from the battery cell 210 is connected to the inner surface of the insulating layer 200.

[0025] During use, the battery cell 210 is installed inside the outer casing 100. When the battery cell 210 is discharging or charging through the power interface 120, it generates heat. This heat accumulates inside the battery cell 210 and is then dissipated outwards. This dissipated heat comes into contact with the graphyne layer 220, rapidly dissipating heat to its outer surface. This prevents heat accumulation near the battery cell 210 (the graphyne layer 220 is existing technology; its specific structure and working principle are not detailed here). The heat is then transferred to the outer surface of the graphyne layer 220. When the heat is discharged to the insulating layer 200, the insulating layer 200 transfers the heat to the outer shell 100 according to the same principle. Then, the outer shell 100, together with the heat dissipation components, exchanges heat with the outside air to achieve the effect of heat dissipation and heat conduction for the battery cell 210. During use, in the square power battery module with the graphdiyne thermal conductive layer, the graphdiyne layer 220 integrally formed on all four sides of the battery cell 210 has ultra-high thermal conductivity, which can quickly conduct the heat of the battery cell 210 to the outer shell 100 in a directional manner, reducing the interface thermal resistance. Together with the heat dissipation components on the outer surface of the outer shell 100, it effectively extends the battery life and ensures the stable operation of the equipment.

[0026] Please see Figures 1 to 3 As a second embodiment of the present invention: based on the description in the above embodiments, further, two sets of heat dissipation components are provided, the two sets of heat dissipation components have the same structure, the two sets of heat dissipation components are respectively installed on the front surface and the rear surface of the outer shell body 100, and the heat dissipation plate 300 has heat dissipation pipes 310 installed in a serpentine structure inside.

[0027] Both the heat pipe 310 and the heat sink 300 are made of brass. The inlet and outlet ends of the heat pipe 310 are connected to external cooling equipment. A cooling fan 320 is installed on the front surface of the heat sink 300, and the exhaust end of the cooling fan 320 is aligned with the front surface of the heat sink 300.

[0028] The side surface of the heat sink 300 away from the cooling fan 320 is connected to the outer surface of the housing body 100. Thermal grease is provided at the connection between the heat sink 300 and the housing body 100. The heat dissipation component is electrically connected to the internal battery cell 210 component through wires.

[0029] In use (the user can install a sensor at the heat-generating point of the battery cell 210 inside the outer casing 100, and connect the sensor to the external heat dissipation component battery cell 210 through a control program and wires, so that when the battery cell 210 heats up, it can automatically start the external heat dissipation component for auxiliary heat dissipation; the circuit connection principle and structure are not described in detail here), after the heat is conducted to the outer surface of the outer casing 100 through the operation steps of the first embodiment, the heat dissipation component is activated, the cooling fan 320 on the front surface of the heat sink 300 rotates, and then the heat sink 300 absorbs the heat conducted from the outer casing 100. Then, the heat dissipation pipe 310 inside the heat sink 300 will input circulating coolant through the external cooling device, and then the heat is dissipated through the heat dissipation pipe 310 in conjunction with the external cooling device. (External cooling equipment is existing technology; users can choose a suitable model of external cooling equipment. The specific working principle and structure will not be elaborated here.) When the heat sink 300 dissipates heat, the cooling fan 320 on the surface of the heat sink 300 also dissipates heat from the heat sink 300, thereby improving the heat dissipation effect of the heat sink 300. At this time, the heat dissipation component is set in the square power battery module with the graphdiyne thermal conductive layer. The high-efficiency thermal conductivity of the graphdiyne layer 220 can be fully utilized. By tightly fitting the heat sink 300 with the battery module shell, the heat conducted by the graphdiyne layer 220 is quickly absorbed, expanding the heat dissipation area. Then, the cooling fan 320 is used to force convection and accelerate air flow, quickly dissipating the heat and effectively reducing the operating temperature of the battery module, ensuring the stable operation of the new energy equipment.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
