Electronic component cooling apparatus

Abstract

A radiator, a heat sink and a tank are disposed on circulating paths. The radiator includes a fan. The tank includes a pump for forcedly circulating fluid. A pump-fan drive unit is provided between the tank and the radiator. The fan and the pump are directly connected to a single motor so that they can be driven by the motor. The pump has a magnet rotor, and a rotor driver. The magnet rotor is accommodated in the tank so as to be rotatable. The rotor driver is fixedly provided in an end portion of an output shaft of the motor. The magnet rotor is magnetically driven to rotate by the rotor driver.
