HEAT EXCHANGER OF THERMOELECTRIC HEATING-COOLING DEVICES Russian patent published in 2013 - IPC F25B21/00 F28F1/04 H01L35/00 F28D21/00 

FIELD: heating.

SUBSTANCE: heat exchanger is designed for heating-cooling of circulating flows of liquid or gas by thermoelectric batteries and may find application in power, chemical, petrochemical, food and other industries. The heat exchanger is made in the form of a forward-flow pipe from a rectangular profile, the width of which complies with width of contact plates of the thermoelectric battery, and inner surfaces are used for heat transfer to a heated (cooled) flow, with transverse partitions installed inside the pipe, which partially cover its throughout section. In the heat exchanger a rectangular profile is applied with the ratio of inner section sides within the limits of 0.2-1, and transverse partitions are made in the form of a bundle of cylindrical rods that close thermal flows of opposite walls of the pipe and installed in a corridor or staggered order perpendicularly to flow direction, besides, the rods are either tightly mounted into opposite walls of the pipe, or are installed on one or several longitudinal plates, pressed with rods into the inner cavity of the pipe.

EFFECT: high ratio of heat transfer from plates of a thermoelectric battery to a heated flow without considerable increase of aerohydrodynamic resistance to its motion.
