Abstract
A fan orifice structure and cover intended for use in conjunction with the outside enclosure, usually containing the outside heat exchanger and compressor, of an air conditioning system. The orifice features relatively complex contours that enhance fan efficiency and reduce radiated noise. The cover in which the orifice structure is incorporated can include a plurality of fan motor support brackets and a motor mount. The orificed cover is intended for fabrication from plastic materials by a molding process to minimize cost and weight, maximize strength and durability and to present an aesthetically pleasing appearance. The entire assembly can be molded into a single piece unit.
