Cooling apparatus for combustion engine

摘要

An air guide ring arrangement is disclosed for guiding air flow around an axial fan of a liquid cooled internal combustion engine having a radiator through which air is drawn by the fan. To facilitate construction of a minimal sized air gap between the air guide ring and the fan blades, the air guide ring is supported by a gibbet or bracket arm fixed to the engine and by a spoked support wheel rotatably borne at the outer circumference of the fan hub.
