Abstract

Abstract—In order to find the effect of radiator oil channel structure, size of the oil passage, oil passage arranged and single-channel allocation small oil passages on the characteristics of radiator heat transfer. In the paper, S imulation for different oil passage of piece radiator, to determine the variation of the heat transfer characteristics and heat transfer efficiency. Studies have shown that small oil passages has a better thermal performance than large oil channel, with the increasing size of oil passage heat transfer efficiency of the radiator increase and decrease then. Keywords-radiator; simulation; oil channel structure I.
