ABSTRACT:
A compact heat exchanger for adjusting the temperature of a stream of liquid of unknown temperature. The heat exchanger includes a hollow core element provided with a passageway which extends therethrough. The core element has an outer surface extending therealong adjacent the passageway. A plurality of thermal electric elements are spaced apart along the outer surface of the core element for providing heating or cooling to the core element. Each thermal electric element has a heat transfer surface which generally conforms to the outer surface of the core element. An assembly is provided for clamping the plurality of thermal electric elements to the outer surface of the core element and includes a heat transfer member for each thermal electric element. The clamping assembly permits the heat transfer members to move independent of each other. The relative independent movement of the heat transfer members facilitates full engagement of the heat transfer surfaces of the thermal electric elements with the outer surface of the core element during expansion and contraction of the core element.
