Heat Transfer Characteristics and Passive Thermal Control Method of Deep-sea Integrated Hydraulic Power Supply
摘要
Abstract
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℃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.关键词
