Lithium-ion power batteries can pay more attention to temperature changes, especially large-capacity high-power lithium-ion batteries for vehicles, which have large working current and large heat output, which will lead to battery temperature rise. If thermal runaway occurs, the situation can be very dangerous.
JOJUN 6500 series silicone thermal pads are used to fill the air gap between the heating device and the radiator or metal base. Their flexibility and elasticity make it possible to cover very uneven surfaces. Heat is transferred from the separator or the entire printed circuit board to the metal case or diffusion plate, thereby increasing the efficiency and service life of the heated electronic components.
Thermal pad are used for filling the two contact surfaces. Thermal pad are ultra soft and have good resilience, so effectively exclude air from the contact interface. The thermal pad are naturally tacky, can be die-cut into various shapes, easy to operate. The thermal conductivity can reach 1.0-12.0w/mk.
Battery heat dissipation mainly adopts air cooling structure, liquid cooling structure and natural convection. Several methods of heat dissipation require heat-conducting silicone sheets. In the air-cooled structure, the thermal conductive silicone sheet is added at the top and bottom of the electrode, so that the heat at the top and bottom is not easy to heat dissipation through the thermal conductive silicone gasket to the metal shell heat dissipation. At the same time, the thermal conductive silicone sheet has a good protection effect on the battery pack due to its high electrical insulation and puncture resistance.
Natural convection heat dissipation, large battery space, good contact with air. The exposed part can be natural heat transfer through air, and the bottom can not be natural heat transfer through the heat sink. The thermal conductive silicone sheet fills the gap between the radiator and the battery, which acts as heat conduction, shock absorption and insulation.
