摘要：
In order to study the influence of the charge air and the coolant on the intercooler heat dissipation performance and the resistance properties, fluid-solid coupling heat transfer model and heat exchanger model were used. Three-dimensional numerical simulation was carried out in order to obtain the water-cooled intercooler internal flow field and temperature field of a heavy diesel engine. The simulation results were verified through the bench test. The results show that return air flow is larger at the inlet and air flow resistance and flow nonuniformity increase. The heat dissipation performance is better with greater charge air flow rate. Outlet temperature is controlled at 30-40 ℃. The cooling effect is better, and meets the requirement. The different cooling water temperature has a greater influence on the cooling performance of the intercooler. The power conversion efficiency can be reduced by 5%-10% with coolant temperature raised 10 ℃. © 2016, Central South University of Technology. All right reserved.
