| 摘 要： | 太阳能光伏电–热（photovoltaic-thermal,PV-T）一体化系统将光伏组件与太阳能热利用系统组合在一起,具有较高的太阳能综合利用效率。针对热管具有高效传热和均温性能的特点,提出一种采用热管冷却技术的太阳能光伏电-热一体化系统;基于光伏电池板传热过程特点及换热器的传热有效度——传热单元数（ε-NTU）法,对热管式PV-T系统的电池板温度、冷却流体出口温度以及系统电效率和热效率等热电转换性能进行了理论分析和计算。结果表明,热管式PV-T系统的电池温度变化幅度在2.5℃以内,系统电效率和热效率分别达到6.99%～7.46%和51.0%～63.2%。该文提出的理论方法为研究热管式PV-T系统热电转换性能提供了一种新的途径,可用来分析和讨论相关参数对热管式PV-T系统性能的影响。
