Abstract
A wireless charger includes an upper housing assembly, a lower housing assembly, a magnetic sheet coil, and a heat dissipation ring. A concave structure is provided on an upper surface of the lower housing assembly, and the concave structure is coupled to the upper housing assembly to form a cavity structure. The cavity structure accommodates the magnetic sheet coil and the heat dissipation ring. The heat dissipation ring is embedded in the magnetic sheet coil and is in contact with the magnetic sheet coil. An upper surface of the heat dissipation ring is coupled to the upper housing assembly. A lower surface of the heat dissipation ring is coupled to a bottom of the concave structure of the lower housing assembly. The heat dissipation ring may transfer heat in the upper housing assembly to the bottom of the lower housing assembly.
