Abstract
A double-layered coaxial double-pass all-glass solar collector tube comprises an outer tube and an inner tube which are arranged coaxially. The outer tube is made of glass. The double-layered coaxial double-pass all-glass solar collector tube is characterized in that the outer tube and the inner tube are fixedly arranged through a fixed supporting part, and a solar absorbing coating is coated on the outer surface of the inner tube. The double-layered coaxial double-pass all-glass solar collector tube has the advantages that two ends of each of the inner tube and the outer tube of the solar collector tube do not have seal or adhesive structures, and the solar collector tube is a double-pass structure and is simple in structure and convenient and easy in production, processing and assembly. The solar collector tube absorbs sunlight, can heat working media such as water or air therein, forms a heat source with temperature ranging from 40 DEG C to 80DEG C, and can be used for vegetable greenhouse warming, sea water desalinization, household solar simple heaters and the like. The double-layered coaxial double-pass all-glass solar collector tube which utilizes the double-pass structure brings convenience for circulation flow and heat exchange of the working media therein.
Description
Technical field
The utility model relates to a kind of double-layer coaxial bilateral full glass solar thermal-collecting tube, belongs to solar energy heat utilization field.Can be used for occasions such as green house of vegetables heating, desalinization, the simple and easy heating installation of household solar energy.
Background technology
Complete glass vacuum sun thermal-collecting tube in the prior art (hereinafter to be referred as thermal-collecting tube) is the core parts of solar energy vacuum tube water heater, and its basic structure is straight shape outer tube, and vacuum chamber and single radial cut formula inner tube structure are mainly used in conventional solar water heater.For enlarging the application of thermal-collecting tube, improve thermal-arrest, heat exchange property, the double-layer coaxial vacuum solar collector tubes has appearred, the double-layer coaxial complete glass vacuum sun thermal-collecting tube of two ends glass inner and outer pipe sealing by fusing structures has been proposed as patent CN200310114503.3, but there is a problem in this kind thermal-collecting tube, promptly when pipe absorbs sunshine in the thermal-collecting tube, interior pipe temperature raises, and produce the temperature difference between the outer tube, at this moment, interior pipe expanded by heating speed causes the excessive and broken inefficacy of thermal-collecting tube two ends ring seal mouth stress greater than outer tube expanded by heating speed.Even adopt ripple struction also to be not enough to solve the different problem that expands between the thermal-collecting tube inner and outer pipes.Patent CN200910096274.4 has proposed a kind of straight way type solar collector tube, this thermal-collecting tube adopts flexible member to carry out transition at two ends, to weaken the different problem that causes that expands between the inner and outer pipes, between the inner and outer pipes of two ends, adopt gluing method simultaneously, will form confined space between the inner and outer pipes.The problem of different generation has also improved production cost and production difficulty simultaneously though this thermal-collecting tube solution inner and outer pipes expands, and is unfavorable for the large-scale production and the marketization.
Summary of the invention
The purpose of this utility model provides a kind of double-layer coaxial bilateral full glass solar thermal-collecting tube, different broken inefficacy of causing of expanding between the inner and outer pipes that the solution prior art exists; Or thermal-collecting tube adopts flexible member to carry out transition to cause production cost high and the production difficulty is big, be unfavorable for large-scale production and market-oriented problem at two ends.
The technical solution of the utility model is: comprise coaxial mounted outer tube and interior pipe, this outer tube and made by glass is characterized in that: fixedly mount by securing supports between described outer tube and the interior pipe; Be coated with sun absorber coatings at described inner tube outer surface.
Described securing supports is elastic supporting member for supporting optical member or non-resilient support member.
Pipe is glass material or metal material in described.
Described outer tube is concordant with the two ends of interior pipe.
The two ends that outer tube is longer than at the pipe two ends in described.
The two ends of pipe in be longer than at described outer tube two ends.
The beneficial effects of the utility model are: these thermal-collecting tube inner and outer pipes two ends do not have sealing-in or bonded structure, are dual channel structure, and are simple in structure, production, processing, easy row easy to assembly.Thermal-collecting tube absorbs sunshine, can be to intraductal working medium such as water or air heat, and the thermal source between forming 40～80 ℃ can be used for green house of vegetables heating, desalinization, the simple and easy heating installation of household solar energy etc.Adopt dual channel structure to be convenient to circulating of intraductal working medium and heat exchange.

The specific embodiment
Referring to Fig. 1～Fig. 4, the utility model thermal-collecting tube is by the interior pipe 4 of outer tube 2, outer surface coating sun absorber coatings 3, and the securing supports between the inner and outer pipes of thermal-collecting tube two ends 1 is formed.
Described securing supports 1 is elastic supporting member for supporting optical member (corrugated elastic sheet metal as shown) or non-resilient support member.
Described outer tube 2 is a glass material, and interior pipe 4 is glass material or metal material, and the outer surface of interior pipe 4 has sun absorber coatings 3, and this coating can be a coating for selective absorption, also can be non-coating for selective absorption.
Described outer tube 2 concordant with the two ends of interior pipe 4 (referring to Fig. 1).
The two ends (referring to Fig. 3) that outer tube 2 is longer than at pipe 4 two ends in described.
The two ends (referring to Fig. 4) of pipe 4 in be longer than at described outer tube 2 two ends.
The two ends of inner and outer pipes of the present utility model do not have sealing-in or bonding, are dual channel structure.
