A fan clutch is a thermostatically-controlled device that exists as an integral component of the automotive cooling system. The automotive industry is the industry involved in the design development manufacture marketing and sale of Motor vehicles In 2007 more than 73 million motor vehicles When the engine is cool or even at normal operating temperature, the fan clutch partially disengages the engine's mechanically-driven radiator cooling fan, generally located at the front of the water pump and driven by a belt and pulley connected to the engine's crankshaft. Radiators and convectors are types of Heat exchangers designed to transfer Thermal energy from one medium to another for the purpose of cooling A mechanical fan is an electrically powered device used to produce an airflow for the purpose of creature comfort (particularly in the heat ventilation, exhaust For information on Wikipedia project-related discussions see WikipediaVillage pump. A pulley (also called a sheave or block) is a Wheel with a groove between two Flanges around its Circumference The crankshaft, sometimes casually abbreviated to crank, is the part of an Engine which translates reciprocating Linear This saves power since the engine does not have to fully drive the fan.
However, if engine temperature rises above the clutch's engagement temperature setting, the fan becomes fully engaged, thus drawing a higher volume of ambient air through the vehicle's radiator which in turn serves to maintain or lower the engine coolant temperature to an acceptable level. A coolant is a fluid which flows through a device in order to prevent its overheating transferring the heat produced by the device to other devices that utilize or dissipate it
Most fan clutches are viscous or "fluid" couplings combined with a bi-metallic sensory system similar to that in a thermostat. Viscosity is a measure of the resistance of a Fluid which is being deformed by either Shear stress or Extensional stress. Bi-metal refers to an object that is composed of two separate Metals joined together A thermostat is a device for regulating the Temperature of a System so that the system's temperature is maintained near a desired setpoint
Normally fan clutches are fairly reliable, but sometimes they fail. A common symptom of fan clutch failure is overheating at idle or in heavy traffic. Bad fan clutches can also cause poor performance of the car's air conditioning system because the fan also cools the air conditioner's condenser, which is directly in front of the radiator. The term air conditioning refers to the cooling and dehumidification of indoor air for Thermal comfort.
Another potential symptom of fan clutch failure (always drawing air at a high rate) in a cold weather climate is that the heating system blows lukewarm air never delivering sufficient hot air.
