Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and examples.
[0023] see Figure 1-Figure 4 , the present invention is mainly made up of glass inner tube 1, glass outer tube 2, absorption coating 3, vacuum interlayer 4, heat conducting medium 5, support frame 6 and metal thermal accelerator 1.
[0024] The glass outer tube 2 of the present invention is set outside the glass inner tube 1, leaving a gap between the two. One end of the glass inner tube 1 passes through one end of the glass outer tube 2 and is sealed with each other, and the end of the glass inner tube 1 passes through. The inner glass tube 1 is filled with a heat-conducting medium 5, and a heat-absorbing coating 3 is attached to the outside of the glass inner tube 1; both the glass inner tube 1 and the glass outer tube 2 are evacuated to form a vacuum interlayer 4 ; The support frame 6 is fixed with the glass inner tube 1.

The invention relates to a solar evacuated collector tube provided with a heat accelerator, belonging to an improved all-glass double-evacuated collector tube. The solar evacuated collector tube comprises a glass inner tube, a glass outer tube, an absorbing coating, a vacuum interlayer, heat-conducting medium and a support frame; wherein, the glass outer tube is arranged outside the glass inner tube, a gap is arranged between the glass inner tube and the glass outer tube, one end of the glass inner tube penetrates through and is sealed and connected with one end of the glass outer tube, and the end of glass inner tube is a condensing head; the glass inner tube is internally filled with the heat-conducting medium, and the outer side of the glass inner tube is attached with the absorbing coating; both the glass inner tube and the glass outer tube are vacuumized. The solar evacuated collector tube is characterized in that the glass inner tube is internally provided with the metal heat accelerator which is positioned at the sealing joint between the glass inner tube and the glass outer tube. The invention has reasonable structural design, accelerates the vaporization process of the heat-conducting medium, and improves the thermal efficiency of the collector tube; furthermore, cold water can be fed at any time without explosion and scale formation, and the solar evacuated collectortube is simple and convenient in installation and maintenance, and long in service life.
Description
technical field [0001] The invention relates to a heat collecting tube, especially a solar vacuum heat collecting tube with a thermal accelerator, which belongs to an improved all-glass double vacuum heat collecting tube; it is mainly suitable for using solar energy to absorb heat so as to provide In case of hot water. Background technique [0002] There are many structures of solar heat collecting tubes in the technology, but the solar vacuum heat collecting tubes with thermal accelerators that can accelerate the vaporization of heat transfer medium have not yet been retrieved. [0003] Existing solar collector tubes mainly include glass inner tube, glass outer tube, absorbing coating, vacuum interlayer, heat conduction medium and support frame. One end passes through one end of the glass outer tube and is sealed with each other, and the end that passes through the glass inner tube is a condensation head; the glass inner tube is filled with a heat-conducting medium, and a ...
