Description
Technical field
The utility model relates to a kind of glassware, particularly a kind of Special Glass Vacuum Tube for Solar Water Heater.
Background technology
The solar water heater is just entering huge numbers of families as a kind of energy-conserving product.As Fig. 1, Fig. 2, shown in Figure 3, solar water heater's core component is the glass-vacuum tube that is made of interior pipe 1 and outer tube 2, the same end of interior pipe 1 and outer tube 2 seals from body respectively, the other end of outer tube 2 links to each other with interior pipe 1 frit seal, between the body blind end, be provided with jump ring 3 and getter 4 at interior pipe from body blind end and outer tube, be used for the relative position of inner and outer pipes is positioned between the inwall of the closed end of pipe and outer tube in wherein jump ring 3 is fixed on, interlayer between the inner and outer pipes is evacuated, getter 4 is used for sponging remaining air after vacuumizing sealing, prior art generally is the end that getter 4 is fixed on jump ring 3.Solar water heater's the thermal efficiency is decided by the effective endotherm area of glass-vacuum tube and the ratio of the gross area.The glass-vacuum tube of prior solar water heater comprises as Fig. 1, Fig. 2, three kinds of versions shown in Figure 3.Glass-vacuum tube shown in Figure 1 is connect to vacuumize by two simple glass pipe boxes and forms, and interior pipe is used to adorn water.This glass-vacuum tube is installed in the solar water heater when going up, and leaves a bigger gap between adjacent two glass-vacuum tube outer tubes, and so, the luminous energy by this gap just can not be absorbed by vacuum tube and participate in the photo-thermal conversion, but quilt has been missed.Therefore, the thermal efficiency by the solar water heater of such glass-vacuum tube assembling is lower.And, when using, cold district is easy to be damaged by frost because interior pipe is equipped with water.Glass-vacuum tube shown in Figure 2 is also connect to vacuumize by two simple glass pipe boxes and forms, but its interior pipe also has been pumped into vacuum, and outer wall of inner tube is coated with one deck photo-thermal conversion film, becomes outer plated film endothermic tube, does not adorn water in the pipe but heat conduction with phase change medium 5 is housed.This glass-vacuum tube is not adorned water because of interior pipe, and good low-temperature characteristics is arranged, and can use at cold district.But because of the caliber of its inner and outer pipes all belongs to the equal diameter pipe, do not have anything to change, still need between tube and tube, reserve the gap when mounted, have the low problem of photo-thermal conversion efficiency equally.Glass-vacuum tube shown in Figure 3 is also connect to vacuumize by two simple glass pipe boxes and forms, but its inner and outer pipes is used to be installed in an end of water tank has carried out the undergauge processing, when being assembled into the solar water heater, distance between the tube and tube can be contracted to zero, thereby has a very high photo-thermal conversion efficiency, but, still have at cold district and use the freezing problem of possibility because pipe still is used to adorn water in it.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and a kind of Special Glass Vacuum Tube for Solar Water Heater of new structure is provided.
To achieve these goals, the utility model has adopted following technical scheme: a kind of Special Glass Vacuum Tube for Solar Water Heater, pipe and outer tube in comprising, the same end of interior pipe and outer tube seals from body respectively, the other end of outer tube links to each other with interior pipe frit seal, between the body blind end, be provided with jump ring and getter at interior pipe from body blind end and outer tube, in wherein jump ring is fixed between the inwall of the closed end of pipe and outer tube, interlayer between the inner and outer pipes is evacuated, pipe is equipped with the heat conduction with phase change medium for sealed at both ends outer plated film vacuum heat absorbing pipe in described in the pipe; Pipe and outer tube are reduced pipe in described, in pipe and the link reduced of outer tube formation undergauge section and link to each other in this undergauge section frit seal, the undergauge segment length of interior pipe in the undergauge section of outer tube and extend to form can contact with the water in solar water heater's water tank touch the water heat pipe.
The diameter of Guan Daduan is more than or equal to the diameter of outer tube undergauge end in described.
Described getter is fixed on the slide glass, can slide in the inner and outer pipes crack, place in pipe from body blind end and outer tube between the body blind end.
Pipe, outer tube all are global formation structures in described.
The utility model Special Glass Vacuum Tube for Solar Water Heater combines the advantage of various glass-vacuum tubes in the prior art, photo-thermal efficient height also has good low-temperature characteristics, be a kind of environmentally friendly machine of assembling energy-efficient water heater, be adapted at using under the various environment.In addition, owing to adopted the inventor's whole reducing forming technique during fabrication, the outside diameter of interior pipe can be made and equal even, thereby help increasing substantially photo-thermal conversion efficiency greater than the undergauge end diameter of outer tube.
