摘要：

A charged air cooler (CAC) with good thermal-hydraulic performances is the guarantee for vehicular turbo charged air system. Mullti-porus media model is adopted in this study to investigate the thermal-hydraulic performance of a CAC and the effect of its structure on the performance. The detailed fin structure can be simplified and thus computational workload can be reduced greatly by this way, and the overall thermal-hydraulic performance investigation of a CAC is possible. The study results show that the inlet and outlet locations of hot-channel have a significant effect on thermal-hydraulic performance and through changing the locations, heat transfer can be enhanced and flow resistance can be reduced.
