Abstract
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.
Claims11
Cooling apparatus for liquid cooled internal combustion engine and the like, comprising:
- a heat exchanger;
- an internal combustion engine;
- an axial blower fan drivingly connected to the engine and disposed between the engine and the heat exchanger, said blower fan having an axle fan blade extending radially from the axle and with a centrally disposed hub means;
- and
- an air guide ring for guiding air flow around the periphery of the fan blades,
- wherein said air guide ring is supported in position by at least one support bracket arm attached to the engine and spoked support wheel means rotatably connected to the outer circumference of the hub means, and wherein the spoked support wheel means is supported at the hub means by roller bearing means and vulcanized rubber at the periphery of the roller bearing.
