Abstract
The air flow between the outlet of a centrifugal fan and the inlet of a surrounding annular radiator or heat exchanger for cooling an internal combustion engine is made uniform by rounding the peripheral edges of the fan wheel support discs so as to enlarge the effective outlet channel for the air and to guide the air in the direction of the lateral regions of the radiator. One or more baffle rings controls the short circuit flow to the inlet of the fan as well as the leakage flow at the shaft side of the fan.
