Embodiment 1
[0040] Such as figure 1 , 3 , 4, the connecting conductive tool 3 is horizontally fixed on the bracket 2, and the connecting conductive tool 3 is a semi-cylindrical body with an outer radius equal to the inner radius of the metal inner tube 11 (e.g. image 3 , 4 (Shown), the surface is flat without pits, stainless steel, the same material as the metal inner tube 11; the main body of the bracket 2 is stainless steel, and the insulating part is ceramic to ensure the rigidity and insulation of the bracket 2; install the medium and high temperature solar collector tube in On the bracket 2, the connecting conductive tool 3 is fixed in close contact with the inner wall of the metal inner tube 11. Adjust the position to ensure that the tail pipe 13 is vertically downward; the wire 10 is embedded in the connecting conductive tool 3 and fixed with bolts, and the wire 10 is made of copper tape Or copper rod, plug both ends of the medium and high temperature solar collector tube 1 with asbe...
Embodiment 2
[0042] Such as figure 2 , 5 As shown, the heat preservation tool 5 is fixed on the bracket 2. The heat preservation tool 5 is made of high temperature resistant mica board, filled with 10mm thick insulation cotton, the main body of the bracket 2 is stainless steel, and the contact between the bracket 2 and the glass outer tube 12 is wrapped with asbestos tape Wrap; install the medium and high temperature solar collector tube on the bracket 2, adjust the position to ensure that the tail pipe 13 is vertically downward; plug the two ends of the medium and high temperature solar collector tube 1 with asbestos plug 4, and use the heat preservation tool 5 to remove the medium and high temperature solar energy The heat collection tube 1 is wrapped; one side of the connecting conductive tool 3 is in close contact with the outer wall of the metal inner tube 11, and the other side is connected to the wire 10. The connecting conductive tool 3 is two semicircles similar to flanges (such as ...
