Results are presented for an experimental investigation of heat exchange and loss of air pressure in staggered six-row banks of air coolers (AC). Curves are presented for the coefficient of convective heat transfer of the fifth transverse row and the aerodynamic drag of six-row banks versus air velocity. It is pointed out that the results obtained can be used in optimizing tube spacing in the heat-exchange sections of AC.
