Abstract:
A cooling system, particularly for a vehicle, comprising:a plurality of at least three heat exchangers, each having two headers and in proximity to each other and positioned to define a housing in the form of a polygonal solid and with the headers of one heat exchanger being in substantial abutment with a respective header of two different, adjacent heat exchangers, at least one of said heat exchangers being adapted to receive a first heat exchange fluid different from a second heat exchange fluid received by at least one other heat exchanger; a radial fan rotatable about an axis and having an impeller within said housing and provided with blades for flowing air generally radially outward through said heat exchangers; a front panel on said housing including an inlet nozzle coaxial with said axis and focused on said impeller; a rear panel on said housing; a shaft extending rearwardly from said rear panel along said axis and coupled to said impeller; and a journal for at least one of said impeller and said shaft to provide for said rotation about said axis; and characterized by the center line of the radially outer part of said blades taken in a plane transverse to said axis being located between said front panel and the center line of said housing and the ratio of the distance from said front panel to said center line of said blades to the diameter of said impeller at the radially outer part of said blades is in the range of about 0.20 to about 0.36.
