【摘要】 设计采用三种管路结构的PV/T集热器，对夏季与冬季的PV/T系统进行实验测试，通过COMSOL对三种管道形状的PV/T集热器进行温度场仿真分析。结果表明：夏季室外温度为24℃时，采用圆角方管的太阳能集热器光热效率可达到44.29%，直角方管41.78%，传统的圆管38.43%；冬季室外温度为1℃时，圆角方光热管效率38.74%，直角方管36.45%，圆管35.16%；采用方管时可更有效的降低光伏板温度，使光伏板温度6min左右降至平稳，圆管集热器需8min左右，并提升光伏板的光电效率。更多还原

【Abstract】 PV/T collectors with three pipe structures were designed and tested in summer and winter. The temperature field of PV/T collectors with three pipe shapes was simulated and analyzed by COMSOL. The results show that when the outdoor temperature is 24 ℃ in summer, the photothermal efficiency of the solar collector using square tube with rounded corner, square tube with rectangular Angle and traditional round tube can reach 44.29%, 41.78% and 38.43%. When the outdoor temperature is 1℃ in winter, the efficiency of rounded square tubes is 38.74%, rectangular square tubes 36.45% and round tubes 35.16%. Square tube can reduce the temperature of photovoltaic panel more effectively, so that the temperature of photovoltaic panel can be reduced to a stable about 6min, round tube collector needs about 8min, and improve the photovoltaic efficiency of photovoltaic panel.更多还原
