Abstract: To better combine the charge air cooler and radiator into turbo engine, a research was proposed to influence the performance of cooling system and the engine itself. The various layouts of charge air cooler with different cooling mediums and radiators were tested via wind tunnel and engine cooling system bench. The result shows that the layout is a vital factor to cooling efficiency, thermal distribution and wind resistance, etc. As for air medium, parallel arrangement has better wind resistance and cooling efficiency than that of cascade arrangement, which, however, is well-distributed. As for water medium, the effect is insignificant. The optimal layout form can be selected based on the cooling medium and installing space.

Key words: engine, cooling performance, charge air cooler, radiator, transmission medium
