Abstract
A fan guide including a guide body, a central frame positioned at a central portion of the guide body and having an outer circumferential region, a plurality of motor fixtures formed at the outer circumferential region of the central frame for fixing a motor coupled with a fan, and at least three straight connecting frames for connecting the guide body and the central frame to each other, wherein one of intersection points among imaginary lines extending the three straight connecting frames is inside the outer circumferential region and the other intersection points among imaginary lines extending the three straight connecting frames are outside the outer circumferential region. By this arrangement, it is possible to decrease the degree of noise resulting from a blade passing frequency while destroying the regularity of a vortex shedding formed at each frame to reduce the interaction between a vortex flow and fan blades, thereby achieving a reduction in noise and flow loss.
