The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of improvement of glass heat collection tube of apparatus for heating water by solar energy is provided, and it should have heat absorption efficiency height, windage characteristics less, easy to installation and maintenance.
The utility model has adopted following technical scheme:
Focus type high temp glass thermal-collecting tube, pipe and outer tube in comprising, interior pipe interts in outer tube, and the outer surface of interior pipe scribbles heat-absorbing material; The two ends of outer tube are the links that is used to install, and an end of two pipes is all made closed, and the other end is airtight to link together, and the cavity between two pipes is in vacuum state; On the outer surface of described outer tube except that the link at two ends, the diameter of the external peripheral surface at all the other positions evenly increases outwards outstanding, and be equipped with the focusing reflector between two pipes, other has some snap ring cards to push down the inner surface that described focusing reflector is fixed in outstanding position; Described focusing reflector occupies half inner circumferential surface of outer tube.
The middle part of the cross section of described focusing reflector is shaped on a prominent rafter, this prominent rafter and outer axial tube line parallel and extend to whole focusing reflector.
The spacing that the summit of described prominent rafter and interior tube-surface keep is the 1-2 millimeter.
Described snap ring is a metal spring.
Described focusing reflector is the metal reflective sheet.
The utility model only needs to rotate thermal-collecting tube when mounted, makes focusing reflector in each thermal-collecting tube all be positioned at the back side of glass heat collection tube in a row; During use, the front hemicycle side face of the interior pipe of all glass heat collection tubes still can directly absorb the heat of solar light irradiation; And pass through the spacing between two two glass heat collection tubes and sunshine excessively, then absorb by the back side hemicycle side face of each focusing reflector reflect focalization to the interior pipe of glass heat collection tube.
The technique effect that the utility model brings is: focusing on 1, that reflector is hidden between the inner and outer pipe not can laying dust incrustation, thereby can guarantee that the long-term maintenance of reflecting effect can not reduce.Though the spacing after 2, outer tube diameter enlarges between two two glass heat collection tubes reduces, and still has certain spacing and is used for circulation of air; This just makes the windage of glass heat collection tube less (comparing with original reverse reflector structure is significantly to reduce), and the probability of generation accident thus is corresponding to be reduced, the then corresponding raising of safety coefficient.3, owing to the pitch enlargement between interior pipe and the outer tube, the spacing between two two glass heat collection tubes is corresponding to be reduced, and it is little to focus on the sunshine and the poor distance of existing reflector that can shine on the reflector; But do not have dust and incrustation owing to focus on reflector, the efficient that solar energy utilizes is high all the better.4, owing to the pitch enlargement between interior pipe and the outer tube, thereby have the focusing reflector that reflective usefulness can be installed in enough spaces, it is easily simple that installment work becomes, and maintenance is also convenient.
