ASSEMBLY OF FAN AND SHROUD

摘要

PURPOSE: An assembly of a fan and a shroud is provided to improve the efficiency of a motor by preventing the reduction of the durability for the motor and smoothly flowing air into the motor. CONSTITUTION: A shroud(60) has a housing portion(62) and a motor support portion(63). The motor support portion is supported by a fixing member to be extended from the edge of the housing portion. A fan(50) is rotated by a motor to be fixed in the motor support portion. A heat shield member(70) is installed in the rear face of the motor and contains an air guide portion. The air guide portion guides an air current from the rotation of the fan toward the motor by inclining toward the radius of the fan. Thereby, the cooling efficiency of the motor is doubled and the reliability of a heat shield is increased.
