| Abstract: | An electronic Hydraulic driving fan cooling system was designed to solve the problem of overheating and overcooling in the construction machinery. The driving system＇s pressure and flow was adjusted by a proportional relief valve. Quantity of dissipation heat varied with the fan＇s rotation speed. The cooling system was applied to construction machinery, including engine coolant cooler and torque converter fluid cooler and hydraulic oil cooler. The experiment shows the cooling medium in the three coolers is kept on the best range. The system has the advantages such as a good fuel economy, low noises, easy to fix. |
