摘　　要：液压动力系统具有压力自补偿、高能源密度特点,适用于深海装备驱动,但大功率、高集成及深海特殊工况下集成液压源过热的问题,则会降低装备可靠性。针对深海集成液压源温控问题,提出并研究了基于深海环境低温回流介质散热的液压源无源热控方法。通过Fluent对构建的液压源耦合传热模型开展了稳态特性分析,揭示了其内部液压油稳态温度由回流介质温度控制。提出了无源热控系统结构,构建了其AMESim数值模型和实验台以开展数值仿真设计及实验验证。结果显示:热控系统数值仿真与实验的误差不超过±5%,并实现了将常温水中的液压源油温控制在45℃左右。所提出的无源热控方法能够有效控制深海液压源油温、改善深海装备可靠性。With the advantages of pressure self-compensating and high energy density,the hydraulic power supply system makes itself a good driver for deep-sea equipment.However,the deep-sea hydraulic power would be easily overheated to decrease the reliability of deep-sea equipment because of its large power,high integration and special working conditions.Aimed at the temperature control problem of deep-sea integrated hydraulic power supply,a novel thermal control method based on low temperature reflux heat dissipation under deep-sea environment is proposed and studied.Firstly,a coupled heat transfer model is established and analyzed to obtain steady-state heat transfer characteristics with Fluent.The result shows that steady state temperature of internal hydraulic oil is determined by the reflux oil temperature.Then,a passive thermal control system is proposed and its AMESim dynamic model and experimental facilities are constructed.The results show that the error between the simulation and experimental results of the thermal control system oil temperature does not exceed±5%,and the final temperature of fluid can be controlled at 45 C in normal temperature water.The proposed method can effectively control fluid temperature of integrated hydraulic power supply and improve the reliability of deep-sea equipment.
