CFD, intercooler, fin structure, heat transfer characteristics, resistance characteristics

Taking the L6230ZLC-10 high-speed diesel engine produced by Zichai Machinery Co., Ltd. as the original engine, the intercooler is modeled and simulated by CFD, and the fin structure with five thicknesses and spacings is used to study the different structures of the intercooler. The influence of heat transfer characteristics and resistance characteristics. The results show that with the new fin size intercooler, the temperature difference between the inlet and outlet of the pressurized air can be increased by a maximum of 17.4%, the pressure drop can be reduced by a maximum of 39.6%, and the overall performance is increased by an average of 39.333%. Provide a certain theoretical design basis.
