Abstract
The utility model relates to a solar collector especially relates to a glass evacuated collector tube. The utility model provides a glass evacuated collector tube, includes outer tube and inner tube, and inner tube one end links to each other with the outer tube, and the other end passes through the support frame to be supported in the outer tube, and the inner tube surface scribbles the solar selectivity and absorbs the coating, and the inner tube is eccentric setting in the outer tube downwards, and the outer tube inner wall scribbles the sunlight reflectance membrane in the mounted position lower part. When the device is installed, the gap between the inner pipe and the outer pipe is large and the inner pipe faces the sun. The utility model discloses multiplicable daylighting area improves glass evacuated collector tube's heat absorption capacity.
Description
Technical field
The utility model relates to a kind of solar thermal collector, relates in particular to a kind of glass heat-collecting vacuum tube, is mainly used in collecting apparatus such as solar water heater.
Background technology
At present, the known glass heat-collecting vacuum tube structure that is used for solar vacuum tube collector is made up of interior pipe and outer tube two glass tubes, bracing frame and accessories, it between the inner and outer pipe vacuum, inner tube outer surface is a solar selective absorbing coating, the daylighting area of this kind thermal-collecting tube is absorber area (projected area of interior pipe), daylighting area is little, and it is few that thermal-collecting tube absorbs heat.
Summary of the invention
At above deficiency, the utility model provides a kind of glass heat-collecting vacuum tube, can increase daylighting area, improves the caloric receptivity of glass heat-collecting vacuum tube.
The technical solution adopted in the utility model is:
A kind of 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, the downward off-centre of interior pipe is arranged in the outer tube, and outer tube wall scribbles the sunshine reflectance coating in the bottom, installation site.
Interior pipe is 3-3.5mm with the clearance distance of outer tube at the minimum clearance place, and the eccentric distance in the interior pipe and the outer tube center of circle is 4-7mm.
Outer tube is coated with the sunshine reflectance coating in 150 ° of scopes on inwall.
The described outer tube wall that is coated with the sunshine reflectance coating partly is reflective mirror.
Vacuum between the utility model outer tube and the interior pipe, inner tube outer surface scribbles the sunshine coating for selective absorption, interior pipe has bracing frame to support, original product structure and production technology are not changed, just interior outer glass pipe is placed with one heart and changed into the eccentric plating reflectance coating technology of placing and having increased outer tube, production technology is simple, realizes easily.
Description of drawings
Fig. 1 is the transverse cross-sectional view of the utility model vacuum heat collection pipe.
Fig. 2 is the longitudinal sectional drawing of the utility model vacuum heat collection pipe.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1 and Figure 2,1 is bracing frame, and 2 is interior pipe, and 3 is outer tube, and 4 is solar selective absorbing coating, 5 sunshine reflectance coatings.Interior pipe 2 downward off-centre are positioned in the outer tube 3, one end sintering, the other end is with stainless steel frame 1 supporting and vacuumize sealing, interior pipe 2 outer walls scribble solar selective absorbing coating 4, interior pipe 2 is 3mm with the clearance distance of outer tube 3 at the minimum clearance place, in pipe 2 be 6mm with the center of circle eccentric distance of outer tube 3, outer tube 3 is coated with sunshine reflectance coating 5 in 150 ° of scopes on the wall within it, outer tube 3 inner wall section that are coated with sunshine reflectance coating 5 are reflective mirror.The pipe 2 direction Chaoyang big in during installation with outer tube 3 gaps.The inwall that outer tube scribbles reflectance coating 5 parts can reflex to the light of penetrating solar selective absorbing coating 4 absorptions of interior pipe, thereby increases daylighting area, improves the caloric receptivity of glass heat-collecting vacuum tube.
Claims (4)
1, a kind of 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, the downward off-centre of pipe is arranged in the outer tube in it is characterized in that, outer tube wall scribbles the sunshine reflectance coating in the bottom, installation site.
