摘　　要：提出利用半导体冷却器对液压油箱的油液进行冷却,设计出集油液冷却和油箱隔板功能为一体的半导体冷却隔板和油箱结构。利用CFD软件对油箱内无隔板和分别安装有常规隔板、新型半导体冷却隔板时油箱内部油液的流动进行数值模拟,得到三种情况下油箱内部油液的速度分布云图、速度矢量图和油液流动迹线图。分析了加入常规隔板和新型半导体冷却隔板后对油箱内部油液流动的影响规律,为半导体冷却型油箱的设计和优化提供参考。The semiconductor cooler is used to cool the oil in hydraulic tank,and the baffle plate with semiconductor cooling function and the oil tank are designed,which integrates the functions of the oil cooling and the oil tank partition.CFD software is used to simulate the oil flow inside the tank when there is no baffle plate,conventional baffle plate and new semiconductor cooling baffle plate.The velocity distribution cloud diagram,velocity vector diagram and oil flow trace diagram are obtained in three cases.The influence laws of oil flow in the tank after adding conventional baffle plate and new type of semiconductor cooling baffle plate are analyzed,which provides reference for the design and optimization of semiconductor cooling tank.
