摘要

FIELD: heat power engineering. ^ SUBSTANCE: regenerative power heater comprises at least two sections which receive at least two heat exchanging units and diffuser and contraction pipe for supplying and discharging fluid to be cooled, and collectors for supplying and discharging the fluid to be heated. The heat exchangers are composed of four branches of heat exchanging pipes. The collectors are connected with the heat exchange pipes through individual pipe plates embedded directly into the wall of the corresponding collector for supplying and discharging air. Each of the heat exchanging pipes is provided with four or five or six bends. ^ EFFECT: enhanced efficiency. ^ 21 cl, 2 ex, 2 tbl
