AXIAL FLOW FAN ASSEMBLY FOR PREVENTING COUNTER FLOW BETWEEN PERFORATED HOLE AND FAN SHROUD

摘要

PURPOSE: An axial flow fan assembly is provided to prevent air from inversely flowing through a space formed between a perforated hole and an axial flow fan by installing a back-flow prevention protrusion at an outer portion of a fan shroud. CONSTITUTION: An axial flow fan assembly includes a driving motor(30) for generating rotational force, an axial flow fan(10) rotated by the driving motor so as to allow air to flow along an axial direction of the axial flow fan(10), and a mounting panel(20) for installing the axial flow fan(10). The mounting panel(20) has a resting section(22) for installing the driving motor(30) thereon and a plurality of support members(23) fixed to the mounting panel(20). The axial flow fan(10) has a cylindrical shape and includes a boss(11) and a plurality of blades(12).
