Abstract

The temperatures at the inlet and outlet of the heat exchanger located inside an engine room are an important design variable which has much effect on the engine room cooling performance of a vehicle and heavy machinery. This study carried out the numerical simulation to investigate three-dimensional thermal and flow characteristics inside the engine room and also to predict the temperatures at the inlet and outlet of the heat exchanger located inside of the engine room that can evaluate the engine room cooling performance of a medium size excavator. The effects of the change in distance between the fan located inside the engine room and heat exchanger, the shroud tip clearance to the fan, and the fan immersion depths of box type shroud and bell mouth type shroud on three-dimensional thermal flow inside the engine room and cooling performance are presented in this paper.
