Abstract
The invention discloses a solar energy heat collecting tube. A port (3) of the heat collecting tube is opened, and a port (4) of the heat collecting tube is sealed or both the port (3) and the port (4) of the heat collecting tube are opened. The heat collecting tube comprises an outer tube (1) and an inner tube (2); the space between the outer tube (1) and the inner tube (2) is vacuous; the cross section of the outer tube (1) is circular; and the cross section of the inner tube (2) is elliptic. On the premise that the diameter of the outer tube (1) of the heat collecting tube is definite, the effective light-receiving area of the elliptic inner tube is larger, the heat absorption efficiency of sunlight within the unit area is higher, and the water temperature is more quickly risen compared with the circular inner tube. In addition, the solar energy thermal-collecting tube can be interchanged and used with the prior common heat collecting tube, thereby facilitating the market promotion.
Description
Technical field
The present invention relates to solar water heater, relate in particular to thermal-collecting tube of solar water heater.
Background technology
Pipe and outer tube in thermal-collecting tube of solar water heater is divided into, thermal-collecting tube one open-ended or two-port are open, thermal-collecting tube comprises outer tube and interior pipe, outer tube and interior pipe two ends collapsed seal are vacuum, prior solar water heater thermal-collecting tube outer tube and interior pipe are coaxial pipe, and promptly the cross section of outer tube and interior pipe is concentric circle.Though this thermal-collecting tube manufacturing process is simple, under the certain situation of outer tube diameter, owing to be subjected to the qualification of its diameter of inner pipe, its effective light-receiving area is restricted, and the efficient that receives sunshine is not high.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of effective light-receiving area is big, and extinction is effective, and water temperature promotes fast solar energy heat collection pipe.
Technical solution of the present invention is: a kind of solar energy heat collection pipe, and the port 3 of thermal-collecting tube is open, port 4 sealings, thermal-collecting tube comprises outer tube 1 and interior pipe 2, be vacuum between outer tube 1 and the interior pipe 2, described outer tube 1 cross section is circular, and described interior pipe 2 cross sections are oval.
A kind of solar energy heat collection pipe, the port 3 of thermal-collecting tube and 4 is opened, and thermal-collecting tube comprises outer tube 1 and interior pipe 2, is vacuum between outer tube 1 and the interior pipe 2, and described outer tube 1 cross section is circular, and described interior pipe 2 cross sections are oval.
Technique effect of the present invention is: because the interior pipe cross section of thermal-collecting tube of the present invention is oval, under the certain situation of outer tube diameter, the effective light-receiving area of pipe was big than pipe in circular in it was oval, therefore, unit are sunshine heat absorption efficiency height, the water temperature lifting is fast.Because the outer tube of thermal-collecting tube of the present invention still adopts circle, do not influence the supporting of thermal-collecting tube and existing water container heat collection pipe jack, can directly utilize existing water container heat collection pipe jack, promptly existing common thermal-collecting tube and thermal-collecting tube of the present invention can exchange use, help marketing.
