Abstract
The utility model discloses a whole-glass solar vacuum heat collecting pipe with reflective function, which has high heat collecting efficiency. The utility model is provided with an outer pipe (1) and an inner pipe (2). A vacuum chamber (4) is formed between the outer pipe (1) and the inner pipe (2) and a black body absorbing layer (3) is coated on the outer wall of the inner pipe. The utility model is characterized in that a specular reflection layer (5) is coated on the lower semi-circular arc surface of the outer wall of the outer pipe. The utility model is applicable for being used as the heat collecting pipe of a solar water heating system.
Description
Technical field
The utility model relates to solar hot water system's heat-collecting part, particularly vacuum heat collection pipe.
Background technology
Full-glass solar energy collecting vacuum tube, the inner and outer pipe interlayer has vacuum chamber, and the heat in can stoping in the pipe distributes to the external world.And because the existence of vacuum chamber, comprise the whole vacuum tube of outer tube relatively, and effectively the solar energy collecting face just reduces, and just, a part of sunshine transmission is crossed vacuum chamber and is not shone outer wall of inner tube.As φ 47 full-glass solar energy collecting vacuum tubes commonly used, its diameter of inner pipe that has that black matrix is coated with rete is φ 37, and invalid collecting region accounts for 21% of total collection area.Solar thermal collector manufactory, though can remedy by the method for additional reflection plate, owing to be subjected to the restriction of all environmental factors, its minute surface reflecting effect is very limited, because of exposing surperficial laying dust dust stratification, loses reflecting effect as reflecting plate.
Summary of the invention
The utility model will solve its active set hot side of solar vacuum heat-collecting pipe and reduce, and the problem of additional reflection plate poor effect, the full-glass solar energy collecting vacuum tube that reflection function is arranged of the present utility model is provided for this reason, and this vacuum heat collection pipe can effectively compensate the problem of the collecting efficiency reduction that reduces to cause because of heat collector surface.
For addressing the above problem, the technical solution adopted in the utility model comprises and is provided with outer tube and interior pipe, have vacuum chamber between outer tube and the interior pipe, outer wall of inner tube is coated with the black matrix absorbed layer, and its special character is to be coated with specular layer on the lower half circle cambered surface of outer tube outer wall.
Described specular layer is coated in the lower half circle cambered surface of outer tube outer wall, and the reflecting surface in reflecting layer is inside, makes the lower half circle cambered surface inner face of outer tube outer wall become minute surface.
The upper semi-circle cambered surface of outer tube is crossed in the sunshine transmission, shines the black matrix layer of outer wall of inner tube, and interior pipe absorbs the solar energy heating interior media.The sunshine (as vertical direction) that vacuum chamber is crossed in part transmission does not shine interior pipe, if outer tube lower half circle cambered surface does not have specular layer, this part sunshine promptly sees through the lower half circle cambered surface.There is specular layer in outer tube lower half circle cambered surface, but this part sunshine just reflected illumination to interior pipe.
The utility model is owing to be coated with specular layer on the lower half circle cambered surface of outer tube outer wall, the sunshine of pipe in not shining so vacuum chamber is crossed in transmission just can be shone interior pipe by the reflection of outer tube lower half circle cambered surface, is absorbed by interior pipe, thereby improves collecting efficiency.Apply specular layer at outer tube lower half circle cambered surface outer wall and realize that easily because minute surface is inside, towards vacuum chamber, extraneous dust can not stain this minute surface.
Description of drawings
Fig. 1 is the radially cross-sectional schematic of the utility model vacuum heat collection pipe.
The specific embodiment
The full-glass solar energy collecting vacuum tube that reflection function is arranged is provided with outer tube 1 and interior pipe 2, has vacuum chamber 4 between outer tube 1 and the interior pipe 2, and outer wall of inner tube is coated with black matrix absorbed layer 3, is coated with specular layer 5 on the lower half circle cambered surface of outer tube outer wall.
Claims (1)
