Abstract

The invention provides an anti-explosion double-vacuum glass heat collection tube. When blank tubes of an inner tube or an outer tube of the anti-explosion double-vacuum glass heat collection tube are processed, reinforced undulated lines or reinforced protuberant lines are processed on single surface or both surfaces of the blank tubes along the axial direction, and the lines have the advantages of effectively improving strength of the heat collection tube, avoiding explosion of the heat collection tube to improve the rate of finished products; moreover, an anti-explosion screen can be added at the heat dissipation stage of the heat collection tube to effectively avoid the damage to human bodies due to the explosion of the heat collection tube.

Description

Anti-explosion double-vacuum glass heat collection tube

Affiliated technical field

The present invention relates to a kind of solar energy heat collection pipe, belong to and utilize the solar energy hot applied technical field.

Background technology

Present solar energy heat collection pipe kind is a lot, and glass heat-collecting vacuum tube, fast heat core type thermal-collecting tube, the two vacuum heat collection pipes of full glass, heat pipe-type glass heat-collecting vacuum tube and special-shaped magnetic thermal-collecting tube etc. are arranged, and the present invention is an anti-explosion double-vacuum glass heat collection tube; And the low easy booster of two its intensity of vacuum heat collection pipe of existing full glass because the stress that the two vacuum heat collection pipes of full glass are produced in process is easy to fragmentation and causes yield rate low, highly according to the set price is not easy to popularize.

Summary of the invention

The invention provides anti-explosion double-vacuum glass heat collection tube, the interior pipe or the outer tube that will have the two vacuum heat collection pipe invalid patent technology of full glass by technological innovation are bellows by technological improvement, and the common tube blank makes single or double increase reinforcement ripple lines when drawing process or strengthens stupefied lines; Also can increase explosion-proof screen, can effectively prevent the explosion of this pipe and can reduce breakage in process of production and increase economic efficiency at the radiating segment of anti-explosion double-vacuum glass heat collection tube.

Technical scheme of the present invention is: anti-explosion double-vacuum glass heat collection tube is made up of outer tube, interior pipe, working solution, it is characterized in that: an end of outer tube and interior pipe is a hot melting cohesion, heat absorption plated film layer is arranged was endotherm section the surface of pipe in its gap vacuumized and cuts, and the section of exposing of interior pipe is a radiating segment; Outer tube and interior pipe are fixed by clamp, and getter is arranged on the clamp; The inner chamber filling working solution of interior pipe also vacuumizes; Outer tube and interior pipe can be bellowss, and lines or distracted lines are strengthened in axially having of single surface of bellows or two surfaces; It is characterized in that: can place working solution prevapourising body in the tube chamber of interior pipe; It is characterized in that: the revealed section of interior pipe can install explosion-proof screen additional.

The invention has the beneficial effects as follows: the outer tube of anti-explosion double-vacuum glass heat collection tube or interior pipe are for being bellows, because single surface of bellows or two surfaces axially has the lines of reinforcement or distracted lines can effectively increase its intensity to prevent booster, particularly again for radiating segment increases explosion-proof screen, even booster can not injure human body yet; Not only can reduce breakage rate in process of production and increase economic efficiency, can also have been reached the purpose of popularizing market fast by consumer group's approval; Because this pipe is difficult for booster, the tube chamber non-scaling of not intaking, be difficult for agingly for this reason, have tangible economic benefit and social benefit.

The specific embodiment

Be illustrated the embodiment of anti-explosion double-vacuum glass heat collection tube with reference to Fig. 1 figure, Fig. 2, Fig. 3 and Fig. 4: anti-explosion double-vacuum glass heat collection tube is made up of outer tube 1, interior pipe 2, working solution 3, with interior pipe 2 inject outer tubes 1 tube chamber in, by the high temperature hot melting cohesion, interior pipe 2 injects outer tubes 1 gap and vacuumizes, it is endotherm section that there is heat absorption plated film layer on the surface of interior pipe 2, and the section of exposing of interior pipe 2 is a radiating segment; Outer tube 1 is fixing by clamp 4 with interior pipe 2, has getter 5 to play the effect that absorbs residual gas on the clamp 4; Vacuumize behind the inner chamber filling working solution 3 of interior pipe 2; The outer tube 1 of anti-explosion double-vacuum glass heat collection tube and interior pipe 2 can be bellowss, also can be bellows and the combining of common tube, lines or distracted lines are strengthened in axially having of single surface of bellows or two surfaces, and this lines draw out when producing the chunk glass pipe; In the tube chamber of interior pipe 2, can place working solution prevapourising body; Can install explosion-proof screen 7 additional at the revealed section of interior pipe 2 and can prevent effectively that booster from injuring human body.

When solar irradiation is mapped to anti-explosion double-vacuum glass heat collection tube, working solution heat absorption vaporization and be with heat to rise to radiating segment in the tube chamber of pipe 2 in it, because the bottom of tube chamber is flowed back in the effect of gravity, and then be subjected to thermal cycle to reach the purpose of heat absorption and heat radiation, non-scaling through heat radiation working solution condensation.
