The efficiency of turbocharged diesel engines can be increased by cooling the charge air. A design approach is presented for liquid-coupled indirect-transfer heat exchanger systems to perform the air-cooling function. The two advantages most commonly cited for this approach to charge-air cooling are (1) the heat exchangers involved are easily packaged so that their shapes can be controlled by judicious design, and (2) simple gas ducting allows for compact machinery arrangements and relatively low charge-air pressure drop. An analytical approach to the design of liquid-coupled indirect-transfer heat exchanger systems is presented. Performance curves are constructed on the basis of this analysis. Four important design conditions, evident from observing these performance curves, are outlined. These performance curves serve as a guide for the design of a liquid-coupled charge-air cooling system.
