摘  要：
为提高车辆冷却系统中多散热器模块匹配的性能,对某装载机散热器模块在风洞测试平台上进行试验研究。试验散热器模块第1排是中冷器和液压油冷却器,第2排为水箱,第3排是变矩器油冷器。在风洞上对模块原型和在原型基础上互换变矩器油冷器进出油口位置的变型进行对比试验。试验结果表明,调整进出油口位置,能提高总的散热量,且对模块中单个散热器的性能影响更大。在设计中可以合理布置散热器进出油口位置,使得模块性能更加优异。

摘  要：
To solve the match problem of multi-heat-exchangers module for vehicle cooling system, an extensive experimental investigation on the effects of inlet-outlet-tube location of heat exchanger module for a loader was carried out in Yinlun wind tunnel. Test results discussed are relatted to 2 inlet-outlet-tube location prototypes, having the same heat exchangers, which includes charge air cooler(CAC), hydraulic oil cooler (HOC), radiator, transmission oil cooler (TOC). In the A type, radiator is up-down stream, and the inlet tube of the other three coolers are in the same side, the outlets in the other side. In the B type, only the inlet and outlet tube of TOC exchanged based on the A type. The analysis shows that if the inlet location changed, the heat transfer will be increased by about 3% in the design air velocity, and pressure drop changed a little. So, the modulation of inlet-outlet-tube location of heat exchangers is a choice for heat exchanger module match design. And in-depth research of heat transfer and pressure loss of cooling module based on test bench is very important for cooling system performance evaluation and matching design at present.
