Scientific definitions for heat exchanger
heat exchanger
A device used to transfer heat from one fluid to another without direct contact of the fluids. Heat exchangers usually maximize the transfer of heat by maximizing the contact surface area between fluids, as when the warmer fluid is passed through a series of coils or thin plates. A car radiator is a heat exchanger, transferring the heat in a liquid that has circulated through the engine to the air.
