any device, as a radiator or a condenser, for transferring heat energy to a cooler medium from a warmer one, for heating or cooling purposes
A device, such as an automobile radiator, used to transfer heat from a fluid on one side of a barrier to a fluid on the other side without bringing the fluids into direct contact.
parallel flow 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.
(plural heat exchangers)
- (physics) Any device (such as a radiator) that transfers heat from one fluid to another via a separating wall
