中小型挖掘机液压油箱的热平衡研究

摘要

This articles takes the 20t Hitachi excavator hydraulic oil tank as the research object,and depending on the analysis of the heat-sinking principle of it,this paper studied the heat-sinking capacity according to the principle of heat balance theory.And based on the series of CFD-ACE+ fluid simulation software,this article simulated the flow and heat transfer characteristics of the oil in the tank.This paper provided a reference for the structure optimization of the excavator hydraulic tank and the heat-balance research,the energy-saving study of the excavator hydraulic system.%以日立20t挖掘机液压油箱为研究对象,在分析其散热原理的基础上,根据热平衡原理,对液压油在油箱中的流动和传热特性进行分析,并依托CFD-ACE+系列流体仿真软件,对其散热能力进行分析仿真,为挖掘机液压油箱的结构优化,以及挖掘机液压系统的热平衡分析和整体的节能优化提供了参考.
