Abstract and Keywords

Abstract: This paper introduces the basic principle of construction machinery vehicle engine cooling system as well as the performance of the main parts, sets up a simulation model for the cooling system using AMESim, and verifies the accuracy of the model by wind tunnel test. The paper analyzes the influence of ambient temperature, pump transmission ratio and radiator fin wave distance on the cooling system to optimize the performance of the cooling system. The study finds that the excessive ambient temperature will make a significant reduction in the performance of the cooling system. The cooling performance of the cooling system can be improved by appropriately increasing the pump transmission ratio and decreasing the fin wave distance of the radiator. Two modified radiators are presented in the paper, and the cooling system performance is improved by optimizing the fin wave distance of the radiators.

Keywords: engine; cooling system; ambient temperature; pump transmission ratio; fin wave distance
