ABSTRACT:
A rectifying unit is disposed axially adjacent to a rear cooling fan. The rectifying unit has a plus-pole heat dissipating fin and a minus-pole heat dissipating fin integrally connected by a terminal plate. The plus-pole heat dissipating fin has an elongation extending axially around the rear cooling fan to have direct cooling air from the fan. The minus-pole heat dissipating fin is fixed to the housing directly or via a heat conductive material to be electrically grounded. Slits are formed on the elongations of the plus-pole heat dissipating fin to have discharging cooling air therethrough. Further, elongations are formed on the both dissipating fins at their inner periphery proximate to an intake window of the housing. Thus, cooling capacity of the rectifying unit is enhanced.
