Abstract
The utility model discloses a solar heat collecting pipe. The technical proposal of the utility model is that the open end between a metal inner pipe and a transparent outer pipe are connected by a telescopic end cover. As the inner pipe is made of metal material, the inner pipe has reliable performance and is difficult to fracture with temperature change. Due to the telescopic end cover, the inner pipe and the outer pipe are not easily interactional under the conditions of heat expansion and cold contraction so as to ensure the normal use of the utility model.
Description
Technical field
The utility model is a kind of solar energy heat collection pipe.
Background technology
Solar energy heat collection pipe commonly used at present is generally the double-glass evacuated tube that is made as one, and the sealing of one end.This vacuum tube is when adding cold water, if the body self-temperature is higher, because hurried cold and hot variation can cause interior pipe to split cruelly.And at this moment whole thermal-collecting tube can only be scrapped, cause use cost higher.
Summary of the invention
The purpose of this utility model is: design a kind of dependable performance, long service life, low, the solar energy heat collection pipe for ease of maintenaince of use cost.
The technical solution of the utility model is to make it by metal inner pipe and transparent outer tube, and open end between the two connects by scalable end cap.Because interior pipe is a metal material, thereby its performance is comparatively reliable, generally is difficult for rupturing when variations in temperature.And, owing to used scalable end cap, also make inner and outer pipes when expanding with heat and contract with cold, be not easy to influence each other, thereby guarantee normal use of the present utility model.
Metal inner pipe of the present utility model and transparent outer tube can be an end opening, the structure of end sealing or the siphunculus of both ends open respectively.
When two pipes were siphunculus, the two ends of metal inner pipe and transparent outer tube were connected by the flexible end cap of annular respectively.
Each annular end cap specifically can be following structure, and it comprises telescopic end face, and edge and outer have the sidewall that cooperates with interior pipe and outer tube respectively in the end face, between sidewall and the inner and outer pipes sealant are arranged.
In addition, receive thermal effect, generally can on the outer wall of metal inner pipe, spray heat absorbing coating for strengthening.

Fig. 1 is the cutaway view of the utility model embodiment;
Wherein, 1, end cap, 2, interior pipe, 3, heat absorbing coating, 4, outer tube, 5, valve.
The specific embodiment
As shown in the figure, present embodiment comprises metal inner pipe 2, transparent outer tube 4, and they are siphunculus.Its two ends respectively have an annular end cap 1 that the space between interior pipe 2 and the outer tube 4 is sealed.The end face of each annular end cap 1 is the extension type structure, and edge and outer have the sidewall that cooperates with interior pipe 2 and outer tube 4 respectively in the end face, and sidewall cooperates with the inner surface of interior pipe 2 and the outer surface of outer tube 4 respectively, and between the mating surface sealant is arranged.Have the valve 5 that is used to vacuumize on one of them end cap 1.
