    摘要:

    对相变材料的储放热过程进行了仿真,获得了某型相变材料吸热、散热工作过程的温度变化曲线,验证了相变材料的储放热特性。针对油箱散热问题设计了可更换换热板的油箱,仿真获得了油箱内油液流动的流线图。仿真分析了无换热板、有换热板和更换换热板后的油箱内温度变化曲线。结果表明:添加换热板后油箱内平衡温度下降3.1 K,更换换热板后,油箱内温度在335 K以下的时间延长1 000 s。通过换热板的添加与更换,有利于液压系统的工作。

    Abstract:

    The heat storage and release process of the phase change material are simulated to obtain the temperature change curves of the heat absorption and heat dissipation process of the phase change material, which verifying the heat storage and release characteristics of the phase change material. A replaceable heat exchanger plate of fuel tank was designed for the heat dissipation problem of the fuel tank. The streamline diagram of oil flow in the fuel tank was obtained. The temperature varying curves of the fuel tank without heat exchanger plates, with heat exchanger plates and after replacing the heat exchanger plate were simulated. The result shows that the equilibrium temperature in the fuel tank drops by 31 Kelvin after adding the heat exchanger plate. After replacing the heat exchanger plate, the temperature in the fuel tank is extended by 1 000 second for less than 335 Kelvin. The addition and replacement of the heat exchanger plates facilitate the operation of the hydraulic system.
