Abstract
Embodiments of the present invention relate to a wireless charging device. The wireless charging device includes a housing, an induction coil, a ferrite, a printed circuit board (PCB), and a fan. The housing includes a first surface and a second surface, a protrusion is disposed on the first surface, and the protrusion is configured to: support a to-be-charged device, and leave a gap between the to-be-charged device and the first surface when the to-be-charged device is installed on the wireless charging device. At least one first air guiding opening and at least one second air guiding opening are disposed on the housing. When the fan runs, the first air guiding opening, the fan, and the second air guiding opening form an air duct that passes through the ferrite and the PCB.
