The cooling module consisted of intercooler and radiator in a sidemounted heavy duty diesel engine compartment was researched and 3D internal flow and heat transfer numerical simulation model was established. Coupled simulations of the cooling air flow and heat transfer were carried out to estimate the heat dissipation performance of the intercooler and radiator under two different layout forms of frontandrear layout and upanddown layout. The results indicate that the upanddown layout of cooling module brings about less change of the coolant outlet temperature of radiator than the frontandrear layout. The hot air outlet temperature of intercooler decreases by 24% with the upanddown layout. In addition, the upanddown arrangements of intercooler and radiator can not only reduce the heat load of engine but also cut down the taking space of radiator and intercooler, which is beneficial to the optimization of the engine cabin space layout.
