摘  要：
柴油发电机组冷却组的中冷器与水散热器相比相对较小,其上端多与水散热器上端平齐,这种布置方式通常不能充分发挥冷却组的冷却能力。将中冷器布置位置下移,使其下端与水散热器平齐,风洞试验研究表明,在风速1.61~4.66m/s范围内,水散热器传热性能可提高0%~5.7%,冷却组风阻下降0%~5.5%,风速3.4m/s时传热性能提高程度最大。风速越大,压降下降幅度越大。

摘  要：
For a diesel generator, the cooling package is usually composed of radiator and charge air cooler (CAC). The front face of the CAC is usually less than the radiator, and the top of the CAC is equal with the radiator, the assemblage of this kind will not reach the maximum performance of the cooling package. Wind tunnel tests showed that, if the bottom of the CAC was leveled with the radiator, when the cooling air speed was between 1.61～4.66 m/s, the heat exchange ability of radiator would rise by 0%～5.7% and the pressure drop of the cooling package would reduce by 0%～5.5%. At the cooling air speeded of 3.4 m/s, the radiator had the best heat exchange performance. The pressure drop of the cooling package decreased with the wind speed.
