Abstract
The utility model discloses a novel solar energy vacuum heat collection tube. The solar energy vacuum heat collection tube comprises an inner metal tube, an outer glass tube, a metal glass transition element and a taper-shaped ripple sealing metal assembly, wherein the outer glass tube and the metal glass transition element are in molten sealing connection; the inner metal tube is sheathed into the outer glass tube; an annular sealing space is formed between the inner metal tube and the outer glass tube; and the taper-shaped ripple sealing metal assembly is completely arranged out of the annular sealing space. The solar energy vacuum heat collection tube disclosed by the utility model has the advantages of simple structure and excellent sealing performance and has the expansion compensation function of a corrugated tube structure.
Description
Technical field
The utility model relates to a kind of new type solar energy vacuum heat collection pipe.
Background technology
Solar energy receives in recent years the increasing concern of people and uses as a kind of new forms of energy of cleanliness without any pollution.And hanker high-temperature field at solar energy, particularly in the slot type collecting system, the heat collector that generally adopts at present is solar vacuum heat-collecting pipe.The slot type collecting system is by the parabolic type solar radiation reflection unit that can follow the tracks of running track from sun, solar radiation to be focused on the vacuum heat collection pipe that the focus of parabolic type reflection unit settles, and is born by vacuum heat collection pipe and collects and the function of transmission heat.
Summary of the invention
The purpose of this utility model is to provide a kind of new type solar energy vacuum heat collection pipe.Characteristics simple in structure, applied range that this solar vacuum heat-collecting pipe has.
Described solar vacuum heat-collecting pipe comprises metal inner pipe, glass outer tube, described metal inner pipe is inserted among the glass outer tube, metal inner pipe and welding are connected by ripple sealing metal assembly at the glassy metal transition element of glass outer tube end, form annular sealed space between metal inner pipe and glass outer tube, be provided with getter element in annular sealed space.Described ripple sealing metal assembly is taper, and all is positioned at the outside of annular sealed space.Described annular sealed space is vacuum.
Characteristics of the present utility model are that described sealing device structure is simple, and sealing property is superior, have the expansion compensation function of bellows structure.
Description of drawings
Fig. 1 is a kind of middle temperature solar vacuum heat-collecting tube structural representation of the utility model.
In figure:
1. metal inner pipe; 2. glass outer tube; 3. glass metal transition element; 4. ripple sealing metal assembly.
The specific embodiment
The utility model provides a kind of solar vacuum heat-collecting pipe, as shown in Figure 1, comprise a glass outer tube 2 and a metal inner pipe 1, coaxial and metal inner pipe 1 passes the inside of glass outer tube 2 to this metal inner pipe 1 with glass outer tube 2, and the outer wall of metal inner pipe 1 has absorber coatings; Glass outer tube 2 is connected with ripple sealing metal assembly 4 by glass metal transition element 3 two ends, then is connected with metal inner pipe 1 by this ripple sealing metal assembly 4, makes and forms a ring vaccum seal cavity between metal inner pipe 1 and glass outer tube 2.The ring vaccum seal cavity is provided with the getter construction package.Wherein take sealing by fusing to be connected between glass outer tube 2 and glassy metal transition element 3.Metal inner pipe 1 and 4 welding of ripple sealing metal assembly.Glassy metal transition element 3 and 4 welding of ripple sealing metal assembly.
Wherein said ripple sealing metal assembly 4 is pyramidal structure, and as shown in Figure 1, the tip of pyramidal structure is towards the two ends of metal inner pipe 1, and the bottom surface is towards glass metal transition element 3.The metal inner pipe 1 that described ripple sealing metal assembly 4 can be caused by thermal expansion by self flexible compensation and the relative displacement of glass outer tube 2, this ripple sealing metal assembly 4 all is positioned at the outside of annular sealed space.
Claims (2)
