斯特林发动机热交换装置的设计与研究

Design and Research of Stirling Engine Heat Exchange Device

热交换装置作为斯特林发动机核心部件,是热能循环的载体。它构成封闭回路,使工质在该循环系统中热胀冷缩,从而推动活塞做功。工质在循环流动过程中总量不变,以fluent软件详细模拟工质流过热交换装置循环运动状态,包括速度、压力和温度,为优化热交换装置内部结构,提高发动机性能提供理论依据。

Heat exchange device as a core component of the Stirling engine is a heat cycle carrier. It forms a closed loop so that the working fluid can be expanded and contracted in the circulatory system, pushing the piston acting. The total mass of working fluid in circulating flow does not change. The fluent software was used to simulate circulation of the working fluid through the heat exchanger means for circulating motion, including velocity, pressure and temperature, to provide a theoretical basis for optimizing the internal structure of the heat exchange device and improve engine performance.
