As a passive heat dissipation medium, silicone thermal pad only plays a heat conduction role in the battery pack, which has no direct relationship with the heat dissipation mode and packaging mode of these new energy vehicle battery packs. When the battery of the new energy vehicle is in operation, it keeps discharging and charging. In the whole working process, the temperature of the battery pack of the new energy vehicle changes at any time, and the change is uneven. There will often be local temperature is too high or local cooling is uneven, and the internal temperature of the battery pack needs to be solved immediately. Whether it is between the cell and the cell, between the battery module and the battery module, or between the battery module and the battery shell, the thermal conductive silicone sheet can be embedded. As long as there is a temperature difference or a large thermal resistance in any location, the thermal conductive silicone sheet can transfer the temperature from high to low through its good heat conduction, and reduce the temperature difference as far as possible. Until new energy vehicles reach a safe operating temperature.
The reliability of thermal conductivity of thermal conductive silica gel sheet is equally important with the life of thermal conductive silica gel sheet. Because its thermal conductivity and reliability are determined to ensure the normal operation of new energy vehicles. The general requirements of thermal conductivity of thermal conductive silica gel sheet are between 1.0-3.0W/ (m·K), which can be met by many manufacturers, but the same thermal conductivity, to ensure 10 years of life at the same time, and in the whole process to maintain high stability of thermal performance of thermal conductive silica gel sheet requires strong technical backing from the manufacturer.
