What are the heat dissipation methods for new energy vehicle power lithium battery packs?

Two heat dissipation methods for power lithium battery packs for new energy vehicles ●Air-cooled structure for power lithium ion battery packs for heat dissipation 1. Install a cooling fan at one end of the battery pack, and leave vents at the other end to accelerate the air flow between the gaps of the batteries , Take away the high heat that occurs when the battery cell is working; 2. Add thermally conductive silicone gaskets to the top and bottom of the electrode end, so that the heat that is not easy to dissipate 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 silicone The high electrical insulation and puncture resistance of the film have a good protective purpose for the battery pack. ●The heat dissipation method of the liquid cooling structure of the power lithium-ion battery pack 1. The heat of the battery cell is transferred to the liquid cooling 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 unified. The strong specific heat capacity of the coolant absorbs the heat generated when the battery cell is working, so that the entire battery pack can operate at a safe temperature. 2. The thermal silica gel has good insulation properties and high resilience, which can effectively prevent the vibration and friction damage between the cells and the hidden danger of short-circuit between the cells. It is the best auxiliary material for the water cooling method. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
