摘要
对光管冷却器和翅片管冷却器的冷却效率进行了对比实验研究 ,结合 Star- CD软件数值模拟的结果 ,指出了原翅片管冷却器的不合理结构参数设计 ,提出了翅片管冷却器结构的改进设计方案 ,实验结果表明 ,改进后的翅片管冷却器的冷却效率明显提高。
The required effectives of EGR-coolers and two EGR-coolers were tested in order to determine their relative efficiencies. The influence of coolant flow characteristics and soot on EGR-coolers was also studied. Based on analysis of testing results and numerical results by Star-CD software, the improving design of the flex-fin cooler was put forward and it is proved to be high efficiency.
