Abstract
The utility model relates to a vacuum glass tube for a metallic heat collector, which comprises double-layer glass vacuum tubes, a metallic tube, a metallic heat collecting fin and heat preservation covers. The utility model is characterized in that a glass tube is made of transparent glass, openings of the double-layer glass vacuum tubes are externally and internally sealed by glass, and middle gaps of the double-layer glass vacuum tubes have vacuums. Further, a metallic communicating tube passes through the middle of the glass tube, the metallic heat collecting fin is fixed onto the metallic communicating tube, a heat absorbing layer is coated on the metallic heat collecting fin, the heat preservation covers fixed onto two ends of the glass tube are used to support and fix the metallic communicating tube, a small hole which is an outside discharging one-way opening is disposed at one end of each heat preservation cover, and two ends of the metallic communicating tube can be screw threads, locking sleeves and conical screw caps. The utility model has the advantages of being convenient to be combined and connected, capable of bearing relatively large pressure and tolerating thermal shock with comparatively large temperature difference, adaptable to large-area heating and hot water projects and being hard to be broken.
Description
Technical field
The utility model relates to a kind of solar vacuum glass tube, especially a kind of glass tube with vacuum with the collector metal device.
Background technology
In existing solar water heater, thermal-collecting tube is most to be the double-deck glass tube that vacuumizes, inner surface at glass tube scribbles heat-sink shell, disclose in the patent 200420011599 at a kind of solar water heater combined metal thermal-collecting tube, metal tube is installed in glass tube with vacuum, heat-sink shell is coated on the metal tube, the major defect of this structure has: one, the surface area of heat-sink shell is little, two, the connection of two vacuum tubes is very difficult, be not suitable for large-area applications, and the air in the vacuum tube can't be discharged.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art and a kind of solar-energy water heater vacuum glass pipe of providing.
The technical scheme that the utility model adopted is: collector metal device glass tube with vacuum, by double-glass evacuated tube, metal tube, the collector metal fin, insulation cover is formed, glass tube is that clear glass is made, the inside and outside glass-dead seal of double-glass evacuated tube, intermediate gaps is a vacuum, a metallic communication pipe is passed in the centre of glass tube, fix a collector metal fin on the metallic communication pipe, scribble heat-sink shell on the collector metal fin, the two ends of glass tube are fixed with insulation cover, insulation cover support fixation metallic communication pipe, one end of insulation cover has aperture, for effluxing unidirectional mouthful, the two ends of metallic communication pipe can be screw threads, cutting ferrule, tapered cup nut, the aperture on the insulation cover.
Compared with prior art, put the metallic communication pipe in the middle of the utility model has the advantages that, be convenient to be connected, can bear big pressure and the bigger thermal shock of the tolerance temperature difference, be applicable to large tracts of land heating and hot water engineering, be difficult for broken.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 is glass-vacuum tube, and 2 is metal tab, and 3 is the metallic communication pipe, and 4 is insulation cover, and 5 for effluxing unidirectional mouthful.
The specific embodiment
Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
Collector metal device glass tube with vacuum, by double-glass evacuated tube 1, UNICOM's metal tube 3, collector metal fin 2, insulation cover 4 is formed, glass tube 1 is made for clear glass, diameter is between 30～200 millimeters, length is between 1000～3000mm, double-glass evacuated tube 1 inside and outside glass-dead seal, and intermediate gaps (3～10mm) air extraction, reach the purpose of insulation, a metallic communication pipe 3 is passed in the centre of glass tube 1, welding (or bonding) collector metal fin 2 on the metallic communication pipe 3, scribble heat-sink shell on the collector metal fin 2, the two ends of glass tube 1 are fixed with insulation cover 4, insulation cover 4 supports, fixing metal cross over pipe 3, an end of insulation cover 4 has aperture, for effluxing unidirectional mouthful 5, the heat absorption of air in the inner chamber is expanded in use, and the back is automatic discharges, and the type of attachment of metallic communication pipe 3 is designed to variation: can be the screw thread screw thread, cutting ferrule connection or tapered cup nut connection etc.
