Description:FIELD OF INVENTION
[0001] Embodiments of a present disclosure relate to a field of cooling fans in vehicles and more particularly to a fan assembly for radiators and a method to assemble the same.
BACKGROUND
[0002] Frequently, vehicles are used for long drives (a period that lasts for at least thirty minutes) at a relatively high speed. An example of driving a high-speed vehicle is on a highway. When such vehicles are driven at relatively high speeds, motion of the vehicle is generally enough to cool the internal combustion engine. At times, the vehicles may employ a clutching mechanism that selectively disconnects the fan from the engine drivetrain in order to minimize parasitic power losses. The engines of the vehicles with clutching mechanism such as trucks may become very hot, especially when trucks are idling, like in a traffic jam. An engine cooling system absorbs heat from the engine is stored in the radiator. For blowing away the heat a cooling fan which is attached to the clutching mechanism is used. The fan helps to pull air in, through the radiator to cool the engine.
[0003] Currently, the existing fan named NF430 is used with T12Nm viscous clutch, having large size fan and the clutch with high cost. NF is a nomenclature named to 11 open blade fan and 430 is the total diameter of the fan. There is need of a fan with reduced hub diameter, reduced total diameter and which is less in weight. The existing fans are not economically beneficial. Also, the existing fan system does not provide correct mounting of the fan on the clutch.
[0004] Hence, there is a need for a fan assembly for radiators and a method to assemble the same which addresses the aforementioned issues.
