高温蓄热技术是太阳能热动力发电系统的关键技术之一,通常利用相变材料(PCM)固液相变时的熔化潜热来蓄热。在轨道的日照期,聚能器将截取的太阳能聚集到吸热器圆柱形腔内,被吸收转化成热能,其中一部分热能传递给循环工质以驱动热机发电,其余的热能被封装在单元换热管上多个小容 High-temperature heat storage technology is one of the key technologies of solar thermal power generation system, which usually uses the latent heat of fusion (PCM) during solid-liquid phase change (PCM) to store heat. During orbital sunshine, the concentrator collects the intercepted solar energy into the cylindrical cavity of the heat absorber, absorbs and converts it into heat energy, a part of the heat energy is transferred to the circulating working medium to drive the heat engine to generate electricity, and the remaining heat energy is encapsulated in the unit exchange Heat pipe more than a small capacity
