DOUBLE FAN TYPE HEAT RADIATOR PROVIDED WITH DUST REMOVING FUNCTION, CONTROL CIRCUIT THEREOF, AND FIN ASSEMBLY UNIT

摘要

PROBLEM TO BE SOLVED: To provide a double fan type heat radiator provided with a dust removing function including a fin assembly unit, cover, a first fan, a second fan, and control circuit.;SOLUTION: The control circuit starts up the first and second fan when receiving a running signal and performs steps (a) and (b) described later respectively for a fixed time when receiving a dust removal signal. The step (a) includes a step to start up the first fan and to stop simultaneously the second fan. The step (b) includes a step to start up the second fan and to stop simultaneously the first fan. Thus the first and second fan can remove dust alternatively and perform dust removal and heat radiation for a fin assembly unit.;COPYRIGHT: (C)2012,JPO&INPIT
