FIELD: mechanical engineering; engine cooling systems.
SUBSTANCE: in proposed fan cooling unit of car engine use is made of pair of overlapping fans to provide uniform flow through radiator of heat exchanger and maximum capacity of fans at limited sizes of electric motors. One fan of each pair has support members placed in front in direction of air flow, and the other has support members placed behind in direction of air flow aimed at minimization of axial sizes of unit.
EFFECT: increased capacity of fans, reduced noise level.
