Thermal material application in Battery cooling

      The heat dissipation of the battery is preferably a thermally conductive phase change material. Thermal phase change is a kind of material that can absorb and release the latent heat of phase change. It has important applications in energy storage. Phase change materials have been paid more and more attention in the heat pipe force system of power battery.

      The thermal management technology of automotive battery using thermally conductive phase change materials has been widely studied. Using the phase change latent heat of phase change materials to control the temperature of the battery can effectively reduce the battery temperature rise under high rate working conditions and improve the temperature uniformity.

      Thermal conductive phase change material is the main principle of temperature control. Using phase change to absorb heat without significant change in its own temperature. Thermal conductive phase change materials are widely used in aerospace, building energy conservation, solar energy utilization, cold chain transportation and other fields. In the application case of battery thermal management, the advantages and disadvantages of air cooling, liquid cooling and phase change temperature control are compared. Thermal conductive phase change materials have attracted much attention because of their excellent performance, high reliability and low cost.

      Generally speaking, the maximum temperature to be solved for battery heat dissipation does not exceed the working temperature and temperature uniformity. In order to make the battery play a good performance and prolong its service life, it is necessary to optimize the structure of the battery, increase heat dissipation facilities, control the temperature environment of battery operation, and the material with heat conduction phase change is conducive to the battery.
