Research of Intercooler Heat Transfer Based on CFD

摘要

The research object of this paper is intercooler used in vehicle. In the paper, the intercooler’s work area is divided into internal flow field and exterior flow field. The author analyzed the structure characteristics of the intercooler fin, and established finite element model in computational fluid dynamics software-Fluent. The unstructured grid is used to mesh. The finite element model is imported to Fluent before simulation. The temperature and pressure of intercooler is shown in result nephogram, and the results show the temperature in exit is higher than requirement. The paper provides scientific basis for structure and performance optimization to intercooler.Key words: Intercooler / CFD / Flow / temperature
