FIELD: heating.
SUBSTANCE: invention relates to heat exchangers and can be used in power engineering and allied industries. Heat exchanger is composed by spiral flexible pipe with turbulence promoters spaced apart at its inner surface and composed of circular ledges. Spiral radius R makes 0.05≤D/R≤0.25, where D is pipe ID, R is spiral radius. Note here that ID d of said ledges makes 0.85≤d/D≤0.98, while spacing t between ledges is 0.45≤t/D≤0.6.
EFFECT: higher efficiency.
