增压空气的冷却可使增压柴油机热负荷降低,这在增压柴油机的工作过程中已被充分证实〔1〕。但是高参数的增压空气中冷系统的获得是与中冷器尺寸的增大和提供冷却空气的风扇尺寸的增大分不开的〔2〕。由此可见,增压空气中冷系统热效率的状况,取决于一些互相矛盾的因素的协调,比如在中冷器和中冷系统的其它元件的尺寸既要满足布置条件,又要符合经济观点的情况下,达到增压空气冷却的最佳效果。 Turbocharged air cooling turbocharged diesel engine can reduce the thermal load, which Turbocharged diesel engine in the work process has been fully confirmed 〔1〕. However, the acquisition of a high-parameter charge air cooling system is inseparable from the increase of the size of the intercooler and the increase of the fan size to provide the cooling air [2]. It can be seen that the condition of the thermal efficiency of the cold system in charge air depends on the coordination of some contradictory factors. For example, the dimensions of other components in the intercooler and the intercooler must satisfy both the layout conditions and economic considerations In the case, the best effect of charge air cooling is achieved.
