Effect Of Height Of Helical Fin On Convective Heat Transfer And Energy And Volume Characteristics Of heat-exchange Sections In Air-cooling Equipment

摘要

Experimental data on coefficients of convective heat transfer of staggered bundles of bimetallic knurled fins, the parameters of which correspond to the heat-exchange sections of third-generation air-cooling equipment, are codified. The thermal-energy expediency of an increase in the height of the fin to 16.5-17 mm as opposed to the 15.2 mm currently employed for a bearing tube with an outside diameter of 25 mm is substantiated.
