COUNTERFLOW RECUPERATOR FOR HIGH-EFFICIENCY HEAT EXCHANGE

摘要

FIELD: heat exchange.;SUBSTANCE: invention relates to heat engineering and can be used in recuperative heat exchangers. In the counterflow recuperator for high-efficiency heat exchange, consisting of inner(s) and external pipes of arbitrary cross-section, located one(s) in the other, as well as supply and discharge headers to them for hot and cold heat carriers, pipes consist of heat conducting pipe sections and heat-insulating spacers located between them, preventing heat propagation along pipes, wherein its outer pipe is either additionally heat-insulated from the outside, or completely made of heat-insulating material.;EFFECT: technical result is higher efficiency of heat transfer.;1 cl, 3 dwg
