Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution:

referring to fig. 1, the inner container of the solar heat collecting tube comprises a heat collecting tube 1, an inner container 2 is arranged in an inner cavity of the heat collecting tube 1, the inner container 2 is made of a metal material with a heat absorption effect, and if an aluminum tube has a strong heat absorption effect, the weight is light. Keep apart through connector 3 and shutoff lid 5 between thermal-collecting tube 1 and the inner bag 2 and avoid touching, the center of inner bag 2 is close to the one side that thermal-collecting tube 1 was shone, increases the heat absorption effect by sunshine irradiation.

An air interlayer 4 is formed between the inner container 2 and the heat collecting tube 1, and the sunlight can irradiate the inner side of the heat collecting tube 1 and the heat rising speed is high in the process that the air interlayer 4 receives the sunlight irradiation; when the sunshine can not be irradiated, the air interlayer 4 is used for isolating the inner container from the outside, the heat loss speed is low, and the heat preservation effect is improved.

Referring to fig. 2 and 3, the cross section of the inner container 2 is in a convex-moon shape, and the convex-moon shape is used for increasing the area of the inner container which can be irradiated, so that the heat absorption effect is improved.

The one end that inner bag 2 is located thermal-collecting tube 1 inboard is provided with shutoff lid 5, and the external diameter of shutoff lid 5 is less than the internal diameter of thermal-collecting tube 1 slightly, avoids inner bag 2 to rock.
