ABSTRACT:
This invention is directed to a fan assembly for use with temperature exchange units and heat exchange units such as a radiator, a heater, an oil cooler, etc. Most automotive vehicles are powered by an internal combustion engine having water, oil and other fluids to be cooled. And, most of the internal combustion engines are associated with a radiator or a heat exchanger unit for cooling fluid in the engine, transmission or other oils and hydraulic fluids. An automotive vehicle operating at a low speed usually requires a fan to assist the radiator or heat exchanger unit in cooling the cooling fluids. However, at higher ram air speed a fan is not normally required to assist the radiator or heat exchanger in cooling the cooling fluids as there is sufficient cooling due to the natural passage of air over the cooling surfaces of the heat exchange units. This invention is directed to a fan assembly which can be used in vehicles having a requirement to dissipate excess heat and a radiator or heat exchanger unit with which a fan assembly can be operated when the automotive vehicle is traveling at a low speed and which fan assembly ceases to operate when the automotive vehicle fluids are sufficiently cooled at a relatively high speed.
