Effect of Row Numbers of Automobile Radiator on Heat Transfer Performance

Abstract

This research work studies the effect of the number of tube rows on heat transfer performance of the automobile radiator. The numbers of tube row of the specimens are 2.3 and 4 rows. Each of heat exchanger is setting in a wind tunnel and exchanges heat between hot water flowing in the tube-side and cold air flowing across the tube bank. From the experiment. It is found that the heat transfer row. Moreover, the models for evaluating the heat transfer and the frictional characteristic are developed and the results agree well with the experimental data.
