Wireless charging technology is derived from wireless power transmission technology. This technology breaks the traditional connecting wire charging, improves the efficiency and convenience of charging, and the usage rate is increasing. Due to the small size of the wireless charger, the working temperature of the internal electronic components must be solved. Thermally conductive graphite sheets and heat dissipation materials such as gaskets can provide a complete set of heat dissipation solutions for the research and development and production of wireless chargers, and solve the heat aggregation of the electromagnetic wave emitters in the enclosed space.
