The author used the FLUENT software, established fluid-solid coupled finite element models of the multi-channel flat tubes in the parallel flow air-air intercooler, adopted three-dimensional numerical analysis for heat transfer process of hot side based on the SIMPLE algorithm, And selected the different channel numbers, hydraulic diameter, respectively, and compared the heat transfer rate, surface heat transfer coefficient and the friction factor. the Calculation results showed that the heat transfer performance and the resistance performance of multi-channel flat tubes, By comparing the heat transfer coefficient with the theoretical calculation value, the friction coefficient and the correlation equation results, respectively, the errors are uniformly in six percentage and six-thirteen percentage, respectively, these data were well correlated. Consequently, this method be able to provide important reference for improving the heat transfer performance of the cooling tubes, and optimizing its structural design.
