Embodiment Construction

[0029] The present invention will be described in more detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] Such as Figure 1~3 As shown, the composition of the straight-through all-glass vacuum solar collector tube of the present invention includes an outer glass tube 1 and an inner glass tube 2; the outer glass tube 1 is a transparent glass tube, and the outer surface of the inner glass tube 2 is attached with a selective solar absorbing coating , or the whole tube is directly made of heat-absorbing glass; the inner and outer tubes are ring-sealed together along the nozzle to form a lumen with openings at both ends; the interlayer between the two tubes is in a vacuum state after exhaust; in order to improve its Vacuum degree, support 3 with getter can be installed in the interlayer.

[0031] It is characterized in that: at least one of the two ends of the heat collecting tube is a special-shaped end with the following structure (for ...

Abstract

The present invention discloses one kind of novel all-glass vacuum solar heat collecting tube and its manufacture process. The vacuum solar heat collecting tube includes inner and outer glass tube with two end ring sealed, and features that at least one end is specially shaped end comprising inner and outer tubes, rotary deformed transition section and short tube and with at least one thin-wall transition part easy to deform elastically. During the manufacture process, the ring hole in some end between the inner and the outer tubes is used in vacuum deairing and vacuum sealing before being processed into the tube mouth. There are no special deairing tube and no conic sealing joint. The present invention has simple structure, easy manufacture and low damage probability, and may be used widely in various kinds of solar water heater.

Description

technical field [0001] The invention relates to an all-glass vacuum solar heat-collecting tube for a vacuum-tube solar heat collector and a vacuum-tube solar water heater / system, especially a straight-through all-glass vacuum solar heat-collecting tube. [0002] The present invention also relates to the manufacturing process of the above-mentioned all-glass vacuum solar heat-collecting tube, especially the straight-through all-glass vacuum solar heat-collecting tube. Background technique [0003] In the mid-1970s, Owens Illinois (Owens Illinois) Company of the United States first developed an all-glass vacuum solar collector (the tube has an opening at one end; for the sake of distinction, this article is called the traditional all-glass vacuum solar collector. Heat pipe). [0004] Based on the introduction of American vacuum heat collectors, my country began to develop all-glass vacuum solar heat collectors in the late 1970s. In the 1980s, scientific research units repres...
