Abstract RU 2031348 C1

FIELD: heat exchange apparatuses. SUBSTANCE: wave-form heat exchange surface is made in form of alternation of protrusions and grooves. They have the same sizes relatively axial line. Adjacent surfaces form diffuser-converging tube channels. Protrusions are made with acute edge and have height h= (1,5. ..2)δ, where d is thickness of boundary layer. Distance between adjacent protrusions is equal to (12...150)h. EFFECT: improved efficiency. 1 dwg
