Heat Exchanger

Device to transfer heat between two physically separated fluids * Counterflow heat exchanger: Heat exchanger in which fluids flow in opposite directions approximately parallel to each other * Cross-flow heat exchanger: Heat exchanger in which fluids flow perpendicular to each other * Heat pipe heat exchanger: See heat pipe * Parallel-flow heat exchanger: Heat exchanger in which fluids flow approximately parallel to each other and in the same direction * Plate heat exchanger or plate liquid cooler: Thin plates formed so that liquid to be cooled flows through passages between the plates and the cooling fluid flows through alternate passages
