ABSTRACT:
An axial flow fan shroud fixes and supports the axial flow fan and a driving motor while surrounding the axial flow fan. The shroud includes a housing having a ventilation hole at the center of the housing and surrounding the axial flow fan; a motor fixing part at the center of the ventilation hole; and air guide vanes or duct between the housing and the motor fixing part for deflecting a part of air blown by the axial flow fan parts needing cooling. The shroud prevents overheating of parts sensitive to heat due to heat of an engine by guiding air blown by the axial flow fan to an area where the parts are installed while avoiding the heated engine. Therefore, low-price products having inferior thermal property can be used so manufacturing costs can be reduced and the degree of freedom in design can be improved.
