Abstract
The utility model relates to vacuum tube heat collector, in particular to a multi-cavity glass vacuum heat-collecting tube, comprising an outer tube and an inner tube, wherein one end of the inner tube is connected with the outer tube while another end of the inner tube is supported in the outer tube via a supporting bracket, the outer surface of the inner tube is coated with a solar selective absorption coating, and the inner tube contains a sealed vacuum glass tube, while the vacuum glass tube is supported in the inner tube via the supporting cards on two ends. The utility model is further provided with a vacuum glass inner tube-cavity, thereby reducing the quantity of the heated water to improve the rising speed of the water temperature in the inner tube effectively and improve the heat starting speed of the water heater.
Description
Technical field
The utility model relates to a kind of vacuum tube collector, relates in particular to a kind of multi-cavity glass heat-collecting vacuum tube, mainly uses solar energy heat collection equipment.
Background technology
Existing glass heat-collecting vacuum tube all includes only glass outer tube and interior pipe usually, vacuum between outer tube and the interior pipe, inner tube outer surface scribbles solar selective absorbing coating, in the interior pipe is recirculated water, water adds heat flow through the sun, but the heating of water heats to interior tube hub direction one by one along inner tubal wall, and the capacity of interior Guan Shui is big, water temperature rising speed is slower, causes the thermal starting of water heater slow.
Summary of the invention
The utility model provides a kind of multi-cavity glass heat-collecting vacuum tube at the problems referred to above, and this thermal-collecting tube has thermal starting advantage faster.
The technical solution adopted in the utility model is:
A kind of multi-cavity glass heat-collecting vacuum tube, comprise outer tube and interior pipe, interior Guan Yiduan links to each other with outer tube, the other end is supported in the outer tube by bracing frame, inner tube outer surface scribbles solar selective absorbing coating, go back the glass tube with vacuum of a sealing of suit in the interior pipe, this glass tube with vacuum is supported in the interior pipe by the support card at two ends.
The glass tube with vacuum of described sealing is suitable with the profile of inner and outer pipe, is the mobile space of recirculated water between the glass tube with vacuum of sealing and the interior pipe.
In being no more than, the volume of the glass tube with vacuum of described sealing manages 2/3 of tube chamber volume.
Vacuum between the utility model outer tube and the interior pipe, inner tube outer surface scribbles solar selective absorbing coating, is recirculated water in the interior pipe, owing to increased tube chamber in the vacuum glass, cause the quantitative change of heated water little like this, the pipe water temperature rate of climb in effectively improving, the thermal starting of water heater is fast.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, wherein 1 is outer tube, and 2 is interior pipe, and 3 is glass tube with vacuum, and 4 is support card.Multi-cavity glass heat-collecting vacuum tube of the present utility model comprises outer tube 1 and interior pipe 2, interior pipe 2 one ends link to each other with outer tube 1, the other end is supported in the outer tube 1 by bracing frame 4, interior pipe 2 outer surfaces scribble solar selective absorbing coating, vacuum between outer tube 1 and the interior pipe 2, in pipe be recirculated water in 2,2 li of interior pipes also have pipe 3 in the vacuum glass of a sealing, by 4 supports of stainless steel support card.Owing to increased a glass tube with vacuum 3, make the quantitative change of heated water little like this, the rate of climb of pipe 2 water temperatures in effectively improving, the thermal starting of water heater is fast.
Claims (3)
1,, a kind of multi-cavity glass heat-collecting vacuum tube, comprise outer tube and interior pipe, interior Guan Yiduan links to each other with outer tube, the other end is supported in the outer tube by bracing frame, inner tube outer surface scribbles solar selective absorbing coating, go back the glass tube with vacuum of a sealing of suit in it is characterized in that in the pipe, this glass tube with vacuum is supported in the interior pipe by the support card at two ends.
2, multi-cavity glass heat-collecting vacuum tube according to claim 1 is characterized in that the profile of the glass tube with vacuum of described sealing and inner and outer pipe is suitable, is the recirculated water space of flowing between the glass tube with vacuum of sealing and the interior pipe.
