WIRELESS POWER TRANSMISSION DEVICE
First Claim
1. A wireless power transmission device for transmitting an electric power to a closed receiver coil of an electronic device, said wireless power transmission device comprising:
- a circuit board;
a heat-dissipating plate disposed on said circuit board for facilitating removing heat that is generated by said circuit board;
a closed transmitter coil disposed on said heat-dissipating plate and connected with said circuit board, wherein in response to an electric current flowing through said circuit board, said closed transmitter coil results in an electromagnetic effect, wherein in response to said the electromagnetic effect, said closed transmitter coil outputs said electric power to said closed receiver coil; and
an encapsulation member for sealing said circuit board, said heat-dissipating plate and said closed transmitter coil, wherein said encapsulation member has a rectangular solid profile, wherein said heat-dissipating plate is partially exposed outside said encapsulation member.

Abstract
A wireless power transmission device includes a circuit board, heat-dissipating plate, a closed transmitter coil, and an encapsulation member. The closed transmitter coil is disposed on the circuit board. The heat-dissipating plate is disposed on the circuit board. The circuit board, the heat-dissipating plate and the closed transmitter coil are sealed by the encapsulation member. Since no gaps are formed in the encapsulation member, the foreign liquid and dust are prevented from being introduced into the encapsulation member. Moreover, since portions of the heat-dissipating plate are partially protruded outside the encapsulation member and partially exposed outside the encapsulation member, the wireless power transmission device of the present invention has enhanced heat-dissipating efficiency.
