Beschreibung
Zusammenfassung:	The invention relates to a solar heat collecting pipe. The solar heat collecting pipe is characterized in that: an inner pipe is installed inside an outer pipe; a vacuum layer is formed between the inner pipe and the outer pipe; the inner wall of the inner pipe is provided with a heat absorption layer; and the outside of the outer pipe is provided with a reflection plating layer. The solar heat collecting pipe has the advantages that: the heat absorption layer is arranged on the inner wall of the inner pipe and is used for absorbing sunlight heat, and the reflection plating layer is arranged outside of the outer pipe and is used for refracting the light which can not irradiate the inner wall of the inner pipe to the inner pipe so as to carry out secondary heating on the heat collecting pipe, thus the heat absorption effect is greatly enhanced and the utilization rate of solar energy is improved.
