Document Type and Number:
WIPO Patent Application WO/2010/026805
Kind Code:
A1
Abstract:
Provided is a wireless power transmission device wherein heat dissipating efficiency is improved without causing size increase of a structure. In a wireless power transmission device (1), a case body (31) for a primary side recharging table (3), and a case body (21) for a secondary side terminal (2) are mounted. The case body (31) houses a coil (35), and the case body (21) houses a coil (25). In such state, the coil (35) and the coil (25) are arranged at positions where the coils electromagnetically couple with each other and are permitted to perform power transmission. The wireless power transmission device (1) is provided with a fan (34). The fan (34) generates an air-cooling air current. The air-cooling air current is permitted to flow inside the case body (31) and inside the case body (21) in a state where a case body pass-through port (37) and a case body pass-through port (27) overlap with each other.
