AN AXIAL FLOW FAN ASSEMBLY

摘要

An axial flow fan assembly is provided to improve heat radiation efficiency of a heat exchanger by adjusting an angle of an axial flow fan at a slipstream of the axial flow fan such that air flow is bent. An axial flow fan assembly comprises a blade(110) that is rotated by a motor(111) such that air is introduced into the axial flow fan assembly, a shroud(120), and a heat exchanger(200). The shroud includes a plenum portion(121), which has a box shape with an open lower portion and guides the air introduced by the blade. The plenum portion is provided at the top surface thereof with an air exhaust port(122) to discharge the introduced air. A motor installing portion(123) is disposed at the center of the air exhaust port to fixedly install the motor. The motor installing portion is supported by a support(124) connected to the plenum portion.
