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

Heat dissipation method of air-cooled structure of power lithium battery pack 1. Install a heat dissipating fan at one end of the battery pack and leave a vent hole at the other end to speed up the flow of air between the gaps of the battery cell and take away the high heat generated during the operation of the battery cell. 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 through the TIF thermally conductive silicone sheet to the metal shell for heat dissipation. At the same time, the high electrical insulation and anti-puncture function of the silicone sheet will affect the battery. The package has a 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, enabling the entire battery pack to operate at a safe temperature. 2. The excellent insulation function and high resilience of thermal conductive silicone sheet can effectively prevent the sensational conflict and damage between the cells and the hidden danger of short circuit between the cells. It is the best auxiliary material for the water cooling plan. 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 through the air, and the bottom part cannot pass through the radiator to dissipate heat. The thermal silica gel fills the radiator and the battery The gap in the middle of the package provides 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 starting is transferred to the battery pack through the thermal conductive silicone film. The preheating battery and thermal conductive silicone film have outstanding thermal conductivity and insulation functions. Wear-resistant function, can effectively transfer heat and protect against wear and short circuit caused by the conflict between the battery pack and the heating plate.
