Problems solved by technology

The single-tube heat collection efficiency of the vacuum tube collector is high, and the effect is good in winter, but it is cumbersome to install one by one, and the combination effect with the building is poor
Focusing reflector has high heat collection efficiency at high temperature, but it is not easy to integrate with buildings, and usually requires an independent installation space
[0003] In addition, the shock absorption and impact resistance of each glass tube should be specially considered during the transportation of the vacuum tube collector, resulting in waste of packaging materials and waste of transportation space
[0004] Therefore, how to overcome the shortcomings of low efficiency and high cost of the existing flat plate collectors, how to overcome the shortcomings of conventional vacuum tube collectors, such as waste of packaging materials in transportation, cumbersome installation process, and difficulty in combining with buildings, is an important issue in this field. important topic

Embodiment Construction

[0024] Such as Figure 1 to Figure 4 As shown, the evacuated tube solar thermal collector plate 1 includes multiple (at least two) vacuum thermal collector tubes 10 .

[0025] Such as Figure 4 As shown, the vacuum heat collecting tube or vacuum tube 10 includes an inner tube 102 and an outer tube 101 , a vacuum layer 103 between the inner and outer tubes 102 , 101 and a circulation channel 104 in the inner tube 102 . The circulation channel 104 in the inner tube 102 of the vacuum heat collecting tube 10 is a straight-through flow channel that enters from one side and exits from the other side. Figure 4 The reference numeral 40 in the middle indicates the external connecting pipeline.

[0026] A plurality of vacuum heat collecting tubes 10 are arranged in parallel, and there is an interval between two adjacent vacuum heat collecting tubes 10, the interval is, for example, 0.1mm to 10mm, because the interval is too small, in Figure 4 is not shown in . Adjacent vacuum heat...

Abstract

The invention aims to provide a vacuum tube solar heat collecting panel, which is convenient to mount. The vacuum tube solar heat collecting panel is characterized by including at least two parallel vacuum heat collecting tubes; a gap is reserved between the two neighboring vacuum heat collecting tubes and adhered through an adhesive material, so as to enable the at least two vacuum heat collecting tubes to form the vacuum panel; and the adhesive material is arranged to the gap.

Description

technical field [0001] The invention relates to a solar heat collecting device. Background technique [0002] Solar collectors are available in the form of flat plate collectors, vacuum tube collectors, and focused reflective collectors. Flat-plate collectors are easy to integrate with buildings, but usually have low heat collection efficiency. The single-tube heat collection efficiency of the vacuum tube collector is high, and the effect is good in winter, but it is cumbersome to install one by one, and the combination effect with the building is poor. Focusing reflectors have high heat collection efficiency at high temperature, but they are not easy to integrate with buildings, and usually require an independent installation space. [0003] In addition, the shock absorption and impact resistance of each glass tube should be specially considered during the transportation of the vacuum tube collector, resulting in waste of packaging materials and waste of transportation sp...
