Heat conduction silica gel coated phase change material heat dissipation plate and battery heat management system

The invention relates to a heat conduction silica gel coated phase change material heat dissipation plate and a battery heat management system. The heat conduction silica gel coated phase change material heat dissipation plate comprises a composite heat dissipation plate and a plurality of battery monomers, the composite heat dissipation plate comprises heat-conducting silica gel and a phase-change material, the heat-conducting silica gel coats the surface of the phase-change material, and the battery monomers and the composite heat dissipation plate are attached alternately in a sandwich structure. According to the heat-conducting silica gel coated phase-change material heat dissipation plate prepared by the invention, the contact thermal resistance between the battery and the composite heat dissipation plate is reduced, the temperature control and equalization capabilities of a battery heat management system are improved, the leakage of the phase-change material can be effectively prevented, the impact resi
