Heat-Exchange Devices With Radiators And Conduit Assemblies
(AREA)
Abstract
A heat exchanger device comprising, in combination with a tube, a flat strip of the same material as the tube, which carries its inner longitudinal edge wound helically in direct contact with the surface of the tube and joined to the tube by means of a joint weld continues along said edge with the same material as the band and the tube, the outer longitudinal edge of the band being provided with interspaced transverse grooves, with the grooves of one turn in an axially stepped relationship with respect to the grooves of the belt. Adjacent turn of the band; the spacing of the adjacent turns being in the ratio of 1 to 5 times the thickness of the band. (Machine-translation by Google Translate, not legally binding)
