HEAT EXCHANGE UNIT Russian patent published in 2015 - IPC F25B21/02 

FIELD: heating.

SUBSTANCE: heat exchange unit consisting of air and water heat exchangers tightened with screws, between which there installed in thermal contact are thermoelectric coolers located in the form of a rectangle and enveloped with a safety barrier; in addition, it is equipped with a terminal box that is located on the outer side of the water heat exchanger and connected to a cavity in which thermoelectric coolers and temperature sensors are located by means of passages made in the wall of the water heat exchanger. In the above passages there located are electrical wires of coolers and sensors, the outputs of which are fixed on the terminal plate installed in the terminal box, to which a cable for external connections is connected through a packing seal.

EFFECT: increasing air tightness of the structure, improving reliability and service life, increasing control efficiency due to possible variation of current-carrying circuits of coolers.
