The common example of a heat exchanger is found in an internal combustion engine, in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, cooling the coolant and releasing the heat generated by the engine, into open air.
One with any experience of Basic Training or being a freshmen at an Academy cannot help but be amused at such passages, "All the grooming tasks seem silly, arbitrary, a waste of her time, just like learning the parts of an Army tank or cleaning radiator coils with a toothbrush because an admiral will be walking through the halls.
Heat is recovered from the VC-5's air-cooled engine using a custom-designed, patent pending heat exchanger by Super Radiator Coils. The VC-15 gen-set uses a more efficient system that recovers the heat from the engine jacket water.
