Embodiment Construction

[0012] figure 1 An example of the present invention is given. figure 1 In this method, two glass tubes with round mouths at one end are used to cover the glass tube 1 and the inner glass tube 2 in a concentric nesting arrangement, and the outer surface of the inner glass tube 2 is made of a selective absorption film by vacuum sputtering, and at the openings of the two glass tubes 1 and 2 Melting and forming a vacuum between the two layers of glass tubes to form a vacuum heat collecting tube with corner scale marks. The corner scale bar mark 3 uniformly distributed according to the 360-degree circumferential angle is formed by not coating the outer surface area of ​​the inner glass tube 2 to form chromatic aberration. The end point 4 of part of the bar mark 3 is marked with a text corner scale mark. Usually these words are 4, 7, 10, 1, can formulate standard regulation: in 4, 7, 10, January, make 4, 7, 10, 1 be at the topmost of heat collecting tube. The surface of the coati...

Abstract

The invention discloses a method for marking a corner of a vacuum heat collecting tube by using corner scales. The vacuum heat collecting tube manufactured according to the method and provided with corner scale marks is characterized by being provided with the corner scale marks uniformly distributed according to the circumference angle of 360 degrees. The method has the advantages that: the vacuum heat collecting tube is provided with the corner scale marks and additional marks; and when the heat collecting tube is horizontally arranged to collect heat and scales formed non-uniformly according to the circumference angle of 360 degrees are formed on the inner wall of an inner glass tube, the scales can be arranged continuously or relatively uniformly by rotating the heat collecting tube, and water is lifted by using the capillarity of the continuously or relatively uniformly arranged scales, so that the inner wall of the heat collecting tube carries water uniformly to realize heat exchange of two-phase flow by the capillarity of the scales when the water level in the horizontally arranged heat collecting tube cannot reach the top. An embodiment is provided by combining the drawing.

Description

technical field [0001] The invention relates to a method and a product for marking the corner of a vacuum heat collecting tube with a corner scale. Background technique [0002] Existing vacuum heat collecting tubes are mostly used in domestic intubated solar water heaters, and some advantages such as low heat loss have not been fully utilized. For example, the manufacture of products that use horizontal vacuum heat collecting tubes for steam generation. Contents of the invention [0003] The purpose of the present invention is to provide a method and product for marking the corners of vacuum heat collecting tubes with corner scales [0004] The method adopted by the present invention to solve the technical problem is to make a corner scale mark on the vacuum heat collecting tube, and use additional markings for marking to make a vacuum heat collecting tube with a corner scale mark. The corner scale marks include patterns and characters; by agreement, the rotation state ...
