FANS FOR AIR CONDITIONERS

摘要

A blower has a sirocco fan of a substantially cylindrical shape and a fan case containing the fan. A motor for driving the fan is arranged outside the case. The case has a pair of inlets formed opposite to each other at both ends of the fan and an outlet so that outside air is sucked through the inlets into the case and diffused from the outlet by the rotation of the fan. A first wind direction plate is mounted on the outer surface of the case and extends substantially to the center of one of the inlet, thereby straightening the flow of the air from the exterior of the case into the inlet. A second wind direction plate extends from the first plate through the inlet into the fan along the axial and radial directions of the fan, thereby straightening the flow of the air in the case.
