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. |
