Example Embodiment

[0025] In the description of the present invention, unless otherwise specified, "plurality" means two or more. The orientation or positional relationship indicated by the terms "inner", "upper", "lower", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying what is meant. The device or element must have a specific orientation, be configured and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral Ground connection; it can be a mechanical connection or an electrical connectio

Abstract

The invention relates to the technical field of solar heat collection tubes and discloses a Fresnel solar and wind power complementation type heat collection tube. An expander in the Fresnel solar and wind power complementation type heat collection tube is connected with the end of an external tube through an expander flange and a second external tube flange, an internal tube is sleeved with the external tube, a gap is reserved between the internal tube and the external tube, a screw panel is arranged between the internal tube and the external tube, a selective absorption coating is arranged on the outer surface of the external tube, and an electric heating element is arranged in the internal tube. According to the Fresnel solar and wind power complementation type heat collection tube, water serves as a heat carrier and flows in the Fresnel solar and wind power complementation type heat collection tube in a spiral mode, even heating is achieved, and local phase change is avoided; furthermore, due to the fact that the electric heating element is arranged and driven through wind power generation, the Fresnel solar and wind power complementation type heat collection tube can provide steam even at night and in rainy days.
