Abstract
A wireless charging device includes a shell, a coil assembly, a main board assembly and a heat dissipation assembly. The shell is defined with first and second air ports, the coil assembly and the main board assembly are located in the shell, the heat dissipation assembly is used for dissipating heat of the coil assembly and the main board assembly. The heat dissipation assembly includes a heat sink and a fan, the heat sink includes a first side and a second side facing away from each other, the coil assembly is arranged on the first side, the fan is arranged on the second side, and the fan is defined with third and fourth air ports. The first air port, the second air port, the third air port and the fourth air port are in communication with one another to form a heat-dissipation air passage located on the second side.
