Background technology
Vacuum heat collection pipe solar thermal collector is the new type solar collecting device growing up on flat-plate solar heat collector basis.Material according to absorber is classified, and vacuum heat collection pipe can be divided into glass absorber vacuum heat collection pipe (or being called all-glass vacuum thermal-collecting tube) and VACUUM HEAT TUBE WITH METALLIC HEAT ABSORBER (or being called glass-metal vacuum heat collection pipe) two large classes.VACUUM HEAT TUBE WITH METALLIC HEAT ABSORBER is quite ripe so far since the eighties development in last century, and especially glass-to-metal seal formula heat-tube vacuum solar collector pipe, has announced national standard in 2005, and implements on November 1st, 2005.Although the temperature rise of glass-to-metal seal formula vacuum solar collector tubes is fast, efficiency is high, there is not bombing hidden danger, but due to glass-to-metal seal complex operation, streamline automatization level is low, and the reasons such as glass-to-metal seal place easily causes gas leakage, and metal copper pipe is expensive, are difficult to promote on a large scale.
Utility model content
The utility model object is to provide a kind of finned all-glass heat pipe evacuated solar collecting tube, can simplified processing process when guaranteeing the conversion efficiency of vacuum heat collection pipe, reduce energy consumption, and reduce cost, and make it to be promoted the use of on a large scale.
The utility model is realized above-mentioned technical purpose by following technological means.
A kind of finned all-glass heat pipe evacuated solar collecting tube, by condensation segment, glass inner tube, glass outer tube, support, absorber plate, connector and getter form, the openend of described condensation segment and glass inner tube is tightly connected, glass inner tube is placed in glass outer tube, absorber plate is wrapped on glass inner tube outer wall, between absorber plate and glass outer tube, be provided with support, absorber plate and glass outer tube are connected and fixed by connector, described getter is welded on above support, the openend of described glass outer tube is connected with glass inner tube sealing by fusing, between glass outer tube and glass inner tube, form vacuum interlayer, described condensation segment is glass tube.
Preferably, described condensation segment is connected with glass inner tube sealing by fusing.
Preferably, described condensation segment and glass inner tube are formed in one.
Preferably, the caliber of described condensation segment is between outer tube caliber and inner tube diameter.
Preferably, described absorber plate is two, and two absorber plates are staggered relatively, be coated on glass inner tube outer surface.
The finned all-glass heat pipe evacuated solar collecting tube that the utility model provides, adopts glass tube as condensation segment, compared to glass-to-metal seal heat pipe, utilizes the technical maturity of glass and glass head seal, easy to operate, reduces the leak rate of glass-to-metal seal place; And adopt glass tube can greatly reduce the cost of raw material as condensation segment, enable to be promoted the use of on a large scale.Glass outer tube makes to form airtight vacuum interlayer between glass inner tube and glass outer tube together with glass inner tube sealing by fusing, has avoided the glass-to-metal seal of heat-pipe vacuum-tube to have all-glass vacuum tube and can bear the advantages such as high vacuum pressure and long service life.
In addition, absorber plate of the present utility model is two, two absorber plates are staggered relatively, be coated on glass inner tube outer surface, the structure of this two-sided absorber plate, absorber plate area is greater than the endotherm area of glass inner tube, compared to all-glass vacuum thermal-collecting tube, has strengthened the endotherm area of whole arm, more solar irradiation can be converted to heat, improve heat absorption efficiency.
Accompanying drawing explanation
Fig. 1 is finned all-glass heat pipe vacuum solar collector pipe schematic diagram described in the utility model.
Fig. 2 be in Fig. 1 A-A to cross sectional plan view.
In figure:
1-condensation segment, 2-sealing by fusing place, 3-glass inner tube, 4-glass outer tube, 5-support, 6-absorber plate, 7-connector, 8-getter.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, but protection domain of the present utility model is not limited to this.
Fig. 1, Figure 2 shows that and an embodiment of finned all-glass heat pipe evacuated solar collecting tube provided by the utility model comprise condensation segment 1, glass inner tube 3, glass outer tube 4, support 5, absorber plate 6, connector 7 and getter 8 that glass tube is made.The caliber of described condensation segment 1 is between outer tube caliber and inner tube diameter.Described condensation segment 1 is connected with the openend sealing by fusing of glass inner tube 3, adopts glass tube as condensation segment 1, and the technical maturity of glass and glass head seal is easy to operate, reduces the leak rate of glass-to-metal seal place; And can greatly reduce the cost of raw material.Preferably, in order to omit the step of sealing by fusing condensation segment 1 and glass inner tube 3, it is one-body molded that described condensation segment 1 and glass inner tube 3 are preferably, can simplified processing process, reduce energy consumption, and reduce cost.Described absorber plate 6 adopts two, and two absorber plates 6 are staggered relatively, be coated on glass inner tube 3 outer surfaces, forms the structure of two-sided absorber plate 6, has strengthened endotherm area, more solar irradiation can be converted to heat, has improved heat absorption efficiency.Glass inner tube 3 is placed in glass outer tube 4, between absorber plate 6 and glass outer tube 4, support 5 is set, for supporting absorber plate 6, between described absorber plate 6 and glass outer tube 4, by connector 7, be fixedly connected with, described getter 8 is welded on to the end of support 5.The openend of described glass outer tube 4 is connected with glass inner tube 3 sealings by fusing, glass outer tube 4 is positioned at the position near described glass inner tube 3 openends with the sealing by fusing place 2 of glass inner tube 3, between glass outer tube 4 and glass inner tube 3, form vacuum interlayer, avoided the glass-to-metal seal of heat-pipe vacuum-tube to have advantages of that all-glass vacuum tube can bear high vacuum pressure and long service life.
