Thermal analysis and optimization of radiator coupling in internal combustion forklift truck cooling system
The cooling system of internal combustion forklift truck consists of engine coolant circulation,trans-mission oil cooling circulation and hydraulic oil cooling circulation.Its performance directly affects the running stability of the whole vehicle.In order to improve the heat dissipation performance of the cooling system and reduce energy consumption,a 1D simulation model of the cooling system is established using AMESim.The influence of the windward area and thickness of the engine radiator,the spatial layout of the radiator and the coolant on the heat dissipation performance of the cooling system is analyzed,and the structural parameters of the radiator are optimized.The results of simulation and experimental study show that the inlet temperature of the engine coolant radiator is reduced by 1.46 ℃ with the optimized cooling system;during the cooling cy-cle of transmission oil,the inlet temperature of the radiator decreases by 20.29℃,and the temperature difference between inlet and outlet increases by 0.35 ℃;during the hydraulic oil cooling cycle,the inlet tem-perature of the radiator decreases by 9.30 ℃.
