Abstract: In order to improve the thermal environment of the loader engine cabin and the heat transfer performance of the radiators to ensure the stable vehicle performance, a 3-D physical model of the loader was built. Virtual wind tunnel and numerical simulation were used to predict the influence of the exhaust system on the cabin thermal environment and radiator performance. The heat transfer power of the radiators was compared under two kinds of exhaust system. Analysis results show reasonable agreement with experiment results, which proves the accuracy of the model. Simulation results show that using insulated exhaust system could significantly reduce the air temperature in the engine cabin. The thermal environment of the engine cabin was improved. The heat transfer performances of the hydraulic oil radiator, the water radiator and the transmission oil radiator ware increased by 9.0%, 7.3% and 6.8%, respectively. The results of this work may provide guidance for vehicle thermal management of the loader.

Key words: vehicle engineering, wheel loader, virtual wind tunnel, numerical analysis, vehicle thermal management
