Abstract

The utility model discloses a glass heating pipe vacuum pipe solar energy collector, which is a glass heating pipe vacuum pipe solar energy collector that made up of a glass heating pipe with a spectrum selective coating surface and an external glass, which are pumped to be a vacuum. The heat collector adopts the solar energy as the energy and is suitable for water heating, boiled water, heating, drying, sun house, conditioning, ice making, electricity generating and ocean water desalination these fields, and further can be used as the heat collecting element for all day collection to the solar energy. The utility model has the advantages of vacuum thermal insulating, anti frost, antifouling, high thermal efficiency and greatly reduced producing cost.

Description

Glass heat pipe vacuum tube solar heat-collecting device

Technical field:

The utility model relates to a kind of heat-pipe vacuum-tube solar heat collector, it is applicable to and utilizes solar energy as the energy, to hot water, boiling water, heating, drying, solar energy housing, air-conditioning, ice making be provided, draw water, field such as generating and desalinization, can be used as the heat-collecting element device of round-the-clock collection solar energy.

Background technology:

Existing heat-pipe vacuum-tube solar heat collector is by glass tube and has and add heat sealing between the metal heat pipe of metal heat-conducting fin that appearance applies spectral selective absorbing coating and vacuumize and constitute, because the coefficient of expansion of glass tube and metal is different, thereby add between the two its difficulty of heat sealing greatly, burst easily, qualification rate is low, cost is high, the life-span is short, thereby this technology and products thereof can't extensively be promoted the use of in the every field of solar energy utilization.

The utility model by retrieval and market survey finds to have the technology and the product of the glass heat pipe vacuum tube solar heat-collecting device of same technical characterictic both at home and abroad so far.

Summary of the invention:

The purpose of this utility model is the glass heat pipe vacuum tube solar heat-collecting device that a kind of cheapness will be provided, be utilize the sealing-in of glass and glass simple, reliable, make it that handling ease, cost are low, dependable performance, the life-span is long, the thermal efficiency is high, thereby help in the every field of solar energy, extensively promoting the use of.

The technical solution of the utility model is such:

It applies the inner layer glass tube of spectral selective absorbing coating and high reflection low layer by the scorification sealing-in by outer layer glass tube, outer surface, the elastic support that will have getter before sealing-in is placed on outer layer glass tube lower support inner layer glass tube, inner layer glass tube exposes outer layer glass tube when sealing-in, chews interlayer with outer layer glass tube and inner layer glass tube with the outer tube exhaust and vacuumizes the back scorification and shut; In the inner layer glass tube and do not adorn or the imbibition core is housed, and after vacuumizing, fill an amount of working medium or fill an amount of working medium, chew scorification with interior pipe exhaust and shut with boiling method.

Description of drawings:

Fig. 1 is the utility model structural representation

The specific embodiment mode:

As shown in the figure, a kind of glass heat pipe vacuum tube solar heat-collecting device, it applies the inner layer glass tube [2] of spectral selective absorbing coating [5] and high reflection low layer [4] by the scorification sealing-in by outer layer glass tube [6], outer surface, the elastic support [8] that will have getter before sealing-in is placed on outer layer glass tube lower support inner layer glass tube [2], inner layer glass tube exposes outer layer glass tube when sealing-in, chews [9] with the outer tube exhaust and the interlayer of outer layer glass tube [6] and inner layer glass tube [2] is vacuumized the back scorification shuts; Inner layer glass tube [2] is interior and do not adorn or be equipped with imbibition core [3], and fills an amount of working medium [8] or fill an amount of working medium [7] with boiling method after vacuumizing, and chews [1] scorification with interior pipe exhaust and shuts.

Tube core [3] can be the imbibition tube core of being made by woven wire, or by the imbibition tube core that spongy porous non-metallic material is made, and also can be the stem stem made by resistant material or the hollow pipe of closed at both ends.

Working medium [7] can be liquid, for example distilled water, methyl alcohol, ethanol, or solution, for example salt solution.

The coated spectral selective absorbing coating of outer surface [5] of inner layer glass tube [2] and highly reflective low layer [4] can be vacuum evaporation sedimentation type, magnetron sputtering type, chemical conversion and electrochemical deposition type, chemical vapor deposition type, brushing type or spectral selective absorbing coating and the highly reflective low layer that fuses type.

Elastic support [8] with getter can be one or both of long-acting type getter and evaporable getter, the evaporable getter needs chew in the outer layer glass tube exhaust and vacuumizes, it is evapotranspired after the sealing-in.
