摘　　要：以太阳能真空集热管为研究对象,基于其几何结构,分析其传热特性,建立了散热量和工质出口温度的计算模型,通过C++编程对比验证模型。最后,利用计算程序,分析一些有机工质的出口温度、吸热量与接收管温度、工质流量之间的关系。Based on the geometric structure of e- vacuated solar collector tube and heat transfer charac- teristics, the calculation model of the working fluids＂ heat release and the outlet temperature is established. A calculation model of heat output and working fluid outlet temperature is established and verification mod- els are compared using C＋＋ computer programming language. Furthermore, the relationships between outlet temperature, heat absorption, heat loss rate and mass flow - rate are analyzed.
