HEAT EXCHANGE PIPE Russian patent published in 2001 - IPC

FIELD: heat engineering, applicable in heat exchangers of various constructions. SUBSTANCE: the heat exchange pipe has external transverse fins with bosses and cavities in the form of waves arranged in the plane of the fin concentrically relative to the pipe, the transverse fins are made on a spiral path, and the adjacent fins have bosses and cavities forming waves of different depth and width; besides, the waves are asymmetric relative to the fin plane. EFFECT: intensified heat exchange due to the increased specific area of diffusion and heat transfer coefficient. 2 dwg
