Viscous coupling for IC engine fan - responds to coolant temp. change and includes heat pump

Heat from circulating coolant is conducted to a control element (4). This element expands and contracts in response to temp. change, thus operating the coupling (1). The conductor can be an externally insulated copper element, or, preferably, a heat pipe (7) located in the drive shaft (2) between th...

More Information
Summary:Heat from circulating coolant is conducted to a control element (4). This element expands and contracts in response to temp. change, thus operating the coupling (1). The conductor can be an externally insulated copper element, or, preferably, a heat pipe (7) located in the drive shaft (2) between the coolant pump (3) and coupling (1). USE/ADVANTAGE - The cooling fan for an IC engine is controlled directly by coolant temp.; and is simple and reliable.
