FIELD: mechanical engineering; heat recuperation. ^ SUBSTANCE: recuperator incorporates channels for two heat-carriers formed by two metal tapes with their surface having unvarying irregularities of preset height, the said tapes being imposed one on and rolled up. Edges of the tapes forming the first heat-carrier channel are tightly coupled, all along the tapes length on one end face of the roll, while the edges of the tapes forming the second heat-carrier channel are tightly coupled on the opposite end face of the roll, both end faces being closed by the walls adjoining to the tapes ends. The aforesaid walls have appropriate heat-carrier inlet into the said channels and outlet thereof. ^ EFFECT: lower production costs, higher reliability and longer life of heat exchangers. ^ 5 cl, 5 dwg |
