Abstract

On an experimental post exploiting parameters of oil-air heat exchanger, made of aluminium pipes, with cross-circular fines were identificated. Simplified method of calculations of oil-air heat exchangers was elaborated. The method includes: heat transfer ratio, mean temperaturę difference, finning ratio, over-all heat transfer coefficient, convective heat transfer coefficients on oil and air sides. The calculation results were compared with ones by Mean Temperature Difference method.
