Abstract
Fan efficiency problems are substantially reduced in a cooling system having a plurality of heat exchangers ( ), ( ), ( ), ( ) positioned with respect to each other to define a housing in the form of a polygonal solid with certain of the heat exchangers being employed in heat exchange fluid while others may be utilized to cool one or more other heat exchange fluids different from the first. A radial fan ( ) is disposed within a space ( ) within the housing and provided with blades ( ) for flowing air generally radially outward through the heat exchangers ( ), ( ), ( ), ( ). The ratio of the location of the center line (d) of the fan blade outer edges ( ) with respect to the front ( ) of the heat exchanger to the diameter (D) of the fan ( ) at the outer edges ( ) is in the range of about 0.20 to about 0.36.
