Abstract:	In view of the contradiction of “difficult low temperature start up” and “low high temperature heat dissipation efficiency” in the hydraulic system, the overall improvement of the performance of hydraulic system equipment is affected. A new hydraulic tank structure constructed by phase change composite material was designed, and ANSYS software was used to model and simulate a new type of tank with composite phase change material successively, and simulation cloud maps such as radial heat transfer and transient heat transfer were obtained, and the changes of heat transfer gradients were analyzed and compared. The simulation results confirm that the phase change composite material can quickly absorb the heat of the oil, so that the heat dissipation effect is higher than that of ordinary oil tanks. The simulation results show that using the high energy storage and high thermal conductivity characteristics of phase change composites, the hydraulic oil can be quickly and uniformly heated in the tank and efficiently dissipated under high temperature conditions, improve the heat exchange efficiency of the oil tank, reduce the volume of the oil tank, and make it have the advantages of “small volume, fast heat conduction, large heat exchange area, uniform oil heating, and strong adaptability to extreme temperature conditions”. It is of great significance to extend the service life of hydraulic oil and hydraulic components, and improve the working reliability and viability of hydraulic system equipment.
