Introduction to the heat dissipation method of the air-cooled structure of the power lithium battery pack

Power lithium battery pack air-cooled structure heat dissipation method 1. Install a heat dissipation fan at one end of the battery pack, and leave a ventilation hole at the other end to speed up the flow of air between the gaps of the battery core and take away the high heat generated during the operation of the battery core. 2. Add thermally conductive silicone gaskets to the top and bottom of the electrode points, so that the heat that is not easy to emit from the top and bottom is conducted to the metal shell through the TIF thermally conductive silicone sheet to dissipate heat. At the same time, the high electrical insulation and anti-puncture function of the silicone sheet affect the battery. The group has a very good maintenance effect. The heat dissipation method of the liquid-cooled structure of the power lithium battery pack 1. The heat of the battery cell is transferred to the liquid-cooled tube through the thermally conductive silicone sheet, and the heat is carried away by the free circulation of the coolant thermal expansion and contraction, so that the temperature of the entire battery pack is consistent. The strong specific heat capacity absorbs the heat generated during the operation of the battery cell, so that the entire battery pack can operate at a safe temperature. 2. The excellent insulation function and high resilience of thermal conductive silicone film can effectively prevent the sensational conflict between the cells and the hidden danger of short-circuit between the cells. It is the best auxiliary material for water cooling plans. Natural convection heat dissipation method for power lithium battery pack 1. This type of battery pack has a large space and excellent contact with air. The exposed part can pass through the natural heat exchange of the air, and the bottom part that cannot naturally exchange heat passes through the radiator to dissipate heat. The thermal conductive silicone sheet fills the radiator and the battery The gap between the group, heat conduction, shock absorption and insulation. 2. The heating film plan is mostly used in the new energy automobile market. The heat of the battery preheating heating film before startup is transferred to the battery pack through the thermally conductive silicone film. The preheating battery and the thermally conductive silicone film have outstanding thermal conductivity and insulation functions. Wear resistance function can effectively transfer heat and protect against wear and short circuit caused by the conflict between the battery pack and the heating plate.
