PROBLEM TO BE SOLVED: To provide a wireless charging device which has favorable sealing effect and maintains the temperature within a safe value range.SOLUTION: A wireless charging device includes a circuit board, a heat-absorbing plate, an inductive transmitter coil, and a casing. The inductive transmitter coil is disposed on the heat-absorbing plate. The casing covers the circuit board, the heat-absorbing plate and the inductive transmitter coil. The heat-absorbing plate includes at least one opening for increasing the entropy of the heat-absorbing plate itself to enhance heat-absorbing capability of the heat-absorbing plate. |
