Abstract
A specially-shaped solar energy glass vacuum tube comprises an inner tube and an outer tube, wherein the backlight surface of the inner tube is designed into the shape of an inwardly concave circular arc; the cross section of the inner tube is crescent, and the amount of water stored in the inner tube is greatly reduced under the condition that the illuminated area of the inner tube is not changed, so as to greatly improve the heat collection and transmission efficiencies; and a part of the upper end of the inner tube is round still to be conveniently sealed with the outer glass tube. The specially-shaped solar glass vacuum tube is manufactured in that way that part of the inner glass tube is heated to be softened, the softened part is pressed into a crescent through a die, the outer surface of the inner glass tube which is pressed into a crescent is plated with an infrared highly reflective metallic film and a selective absorption coating, and the inner tube is encapsulated in the outer glass tube and vacuumized to achieve the purpose of efficient heat collection.
Description
Technical field
The utility model relates to a kind of sun and utilizes technology, particularly a kind of special-shaped solar glass-vacuum tube.
Background technology
Its interior outer glass pipe of common solar energy glass vacuum pipe all is round, and use finds that the water amount in the interior pipe is too many, causes overall efficiency lower.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of special-shaped solar glass-vacuum tube of efficient heat-collecting.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of special-shaped solar glass-vacuum tube, and pipe and outer tube in comprising are characterized in: the circular arc that the shady face of pipe is set to concave in described.
The utility model compared with prior art, the original shady face of the interior pipe of the solar water heater glass-vacuum tube circular arc that is set to concave, the cross section of interior pipe forms crescent, do not changing under its light-receiving area condition, water amount in significantly reducing in the pipe, thus the efficient of its thermal-arrest transmission significantly improved.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
The specific embodiment
A kind of special-shaped solar glass-vacuum tube, pipe 1 and outer tube 2 in comprising, the circular arc that the shady face 3 of described interior pipe 1 is set to concave.In pipe 1 cross section form crescent, the light-receiving area of interior pipe is constant, interior pipe 1 upper end some be still circularly, is beneficial to seal with outer glass pipe.Its preparation method is: earlier the inner layer glass tube portion is heated to it and softens, with mould it is pressed into crescent again; Plate anti-metal film of infrared height and coating for selective absorption being pressed into meniscate glass inner tube outer surface, encapsulation is advanced in the outer glass pipe and is vacuumized, and makes it to reach the purpose of efficient heat-collecting.
Claims (1)
1. a special-shaped solar glass-vacuum tube is managed and outer tube in comprising, it is characterized in that: the circular arc that the shady face of pipe is set to concave in described.
