Abstract

PURPOSE:To facilitate incorporation into an equipment by installing a semiconductor circuit for power supply to a heat sink with a fan and a fan motor and changing these apparatus into a unit including even a board having a connecting terminal with an external circuit. CONSTITUTION:A fan 2 belongs to one kind of centrifugal fans, and air is sucked to the upper section of the fan 2 bored to a heat-sink upper plate 8 from a suction hole, and forwarded to the outer circumferential section of the fan 2. Air fed by the fan 2 is introduced to a semiconductor circuit 5 for power supply along the flow path of a heat sink 1 with cooling fins. Air cools the semiconductor circuit 5 for power supply and the heat sink 1 with the cooling fins in a process in which air passes through the fin section for the heat sink 1 with the cooling fins and is discharged outside a semiconductor circuit unit for power. Accordingly, the semiconductor circuit for power supply is incorporated easily into an equipment, thus miniaturizing a device, then simplifying maintenance.
