FIELD: heating.
SUBSTANCE: heat-exchanger contains tube profile with heat-exchange fins on outer surface. The tube profile is provided with coupling flange on at least one end with at least one flow hole for one of both fluid media, for hot gas in particular. In order to provide optimum structural ratio, it was proposed to use shaped pipe as a profile from folded metal sheet, which heat-exchange fins arranged in profile longitudinal direction are formed by corrugated profile, by corrugated surfaces of folded metal sheet in particular.
EFFECT: providing heat-exchanger suitable for creation of high dynamic temperature fluctuation.
