A method for evaluating the efficiency of heat transfer from the outer surface of finned heat exchange pipes to atmospheric air in air cooling apparatus is considered

A variant of reconstruction of the tube bundle of an air-cooling apparatus designed for propane con-densation is considered in order to increase the intensity of heat transfer from the outer surface of finned tubes to atmospheric air.

The method of estimation of efficiency of heat transfer of air in air coolers at different values of the coefficient of finned heat exchanger tubes.

The influence of the structural material of heat exchange pipes and the thermal resistance of contamination of the heat transfer surface on the intensity of heat exchange is considered. The necessity of taking these factors into account when designing heat exchangers is shown
