There is provided a solar collector comprising a solar heat absorber plate thermally conductively connected to the evaporator section of a metal heat pipe. The absorber plate and the evaporator section are surrounded by an evacuated glass envelope joined to the heat pipe at the open end of the evaporator section by a glass-metal seal. The condenser section of the heat pipe is spaced from the evaporator section and is formed for installation in a heat transport system. A flexible portion joins the respective open ends of the evaporator section and the condenser section, such flexible portion having an outer diameter smaller than the inner diameter of the evaporator section and that of the condenser section. The moment of resistance of this flexible portion is smaller than the moment that can be withstood by the glass-metal seal. |
