摘要/Abstract

摘要： 为了解决增压内燃机中冷器和散热器布置匹配问题，研究中冷器和散热器不同布置形式的散热特点及对内燃机冷却系统性能的影响.利用风洞试验和内燃机冷却性能台架试验，结合中冷器中不同的流动介质，针对不同的布置形式进行研究.试验结果表明:布置形式不同，对各自散热效率、热分布、模块整体风阻等的影响较大；风冷式传导介质，串联式风阻较并联式大，并联式散热效率优于串联式，但串联式热分布更均匀；水冷式传导介质，两种形式各方面差异较小.在实际设计中，根据内燃机中冷器不同的冷却介质、整体空间等选择最优的布置形式.

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
