Abstract
The utility model provides a vacuum solar energy heat collection tube, belongs to the technical field of solar thermal application, and in particular relates to the technical field of vacuum solar energy heat collection tube manufacturing. The vacuum solar energy heat collection tube comprises an inner glass tube, an outer covered glass tube, a butt tube and locating rings, wherein a vacuum interlayer is formed between the inner glass tube and the outer covered glass tube, the inner glass tube is coated with a heat collection coating layer, and the butt tube is sealed at the sealed ends of the inner glass tube and the outer covered glass tube; unpainted sections, which are not painted with heat collection coating layer, are arranged on the inner glass tube close to the annular sealed ends, and the locating rings are arranged on the unpainted sections of the inner glass tube in a sleeved manner. The arrangement of the vacuum solar energy heat collection tube guarantees that the two tubes are coaxially arranged and are more stable, reduces damage in production, improves percent of pass, facilitates mechanical mass production, and can realize production automation.
Description
Technical field
The utility model belongs to solar energy utilization technique field, particularly a kind of manufacturing technology field of vacuum heat collection pipe of solar energy.
Background technology
Existing all-glass heat tube type evacuated solar collector tube comprises inner glass tube, cover glass pipe, butt tube, locating ring, be provided with vacuum interlayer between described cover glass pipe and inner glass tube, scribble the thermal-arrest coating on described inner glass tube, described butt tube is sealedly connected on the loop seal end of described cover glass pipe and inner glass tube, described locating ring is nested with on inner glass tube, and be supported on described inner glass tube and cover glass pipe, the chances are at 1/2nd places of distance loop seal less than or equal to whole support heat pipe pipe range in the position of present locating ring; Locating ring generally is positioned on the thermal-arrest coating, the thermal-arrest coating that such layout is blocked, the daylighting area of the pipe of impact, the retainer ring position at middle part partially in addition, due to the effect of potential energy, affect the locating effect of locating ring after use, namely affected the concentricity of its inner and outer pipe.
In addition, inner glass tube is when plating thermal-arrest coating, and due to the restriction of existing technique, the blank space of about 35mm can appear in its openend, and the blank space on vacuum heat collection pipe Cheng Guanhou inner glass tube still exists.
Summary of the invention
The utility model provides a kind of vacuum heat collection pipe of solar energy, and purpose is to solve the position of existing locating ring, blocks coating, and affects to a certain extent the problem of the concentricity of inner glass tube and cover glass pipe.
The utility model comprises inner glass tube, cover glass pipe, butt tube, locating ring, between described inner glass tube and described cover glass pipe, vacuum interlayer is set, be coated with the thermal-arrest coating on described inner glass tube, described butt tube is sealedly connected on the loop seal end of described inner glass tube, cover glass pipe; Described inner glass tube is provided with one section clear band of not plating the thermal-arrest coating near described loop seal end, and described locating ring is nested with in the above clear band of described inner glass tube.
The utility model is arranged on locating ring the clear band of inner glass tube, can not block the thermal-arrest coating like this, does not affect the daylighting area of inner glass tube, has guaranteed endothermic effect; Have locating ring to be supported on the top of inner glass tube and cover glass pipe again, guaranteed that two pipes are coaxial, also more stable, reduced breakage during production, qualification rate improves, and is convenient to simultaneously the mechanization batch production, can realize the production automation.
Locating ring described in the utility model is not more than 35mm apart from the distance of loop seal end.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
