NOVELTY - A heat-dissipating wireless charger has a casing. The entire surface of the outer casing is provided with a heat dissipating coating. The heat dissipating coating is obtained by forming liquid-phase coating using 13-30% silica sol, 13-30% graphene oxide dispersion and 40-75% polystyrene emulsion, immersing to-be-dissipated carrier in the coating, removing after 8-10 minutes, drying at room temperature, repeating the process thrice, and heat-treating at 300 degrees C. USE - Heat-dissipating wireless charger. ADVANTAGE - The heat-dissipating coating transfers the heat inside the charger to the casing through heat-dissipating coating on the inner surface of the casing, and the outer surface of the heat dissipation layer is transmitted to the surrounding environment, thus heating of wireless charging equipment is prevented.
