摘要
为强化轻量化液压油箱的散热能力,基于传热学原理,利用热管高效传热的特性,配合多层螺旋折流板,设计了一种储油散热一体化的轻量化液压油箱,完成了样机加工和试验台的搭建。以样机散热功率和总传热系数为研究目标,探究了不同冷却风量、加热温度和水流量对油箱散热性能的影响,针对试验中的新发现进行了样机改进试验。结果表明,在一定范围内增加冷却风量、提升加热温度和水流量均能强化油箱的散热性能。在研究工况范围内,样机最高散热功率达到了1.13 kW,散热功率密度为22 kW/m^(3)。
In order to strengthen the heat dissipation capability of the lightweight hydraulic tank,a lightweight hydraulic tank with integrated oil storage and heat dissipation was designed based on the principle of heat transfer,utilizing the efficient heat transfer characteristics of heat pipes,and incorporating multi-layer spiral deflectors,and the prototype machining and test rig construction are completed.The tests investigate the effects of different cooling air volume,heating temperature and water flow rate on the heat dissipation performance of the tank,using the cooling power and total heat transfer coefficient of the prototype as the research objectives,and the prototype improvement test is carried out according to the new findings of the test.The results show that increasing the cooling air volume,heating temperature and water flow rate within a certain range can enhance the heat dissipation performance of the tank.The maximum cooling power of the prototype reached 1.13 kW and the cooling power density was 22 kW/m^(3) over the range of operating conditions studied.
