Embodiment Construction
[0013] Such as figure 1 , 2 As shown, a stainless steel insulation pipe for solar collectors of the present invention includes an L-shaped stainless steel inner pipe 1, one end of which is provided with a flange connected to the oil circuit, and the other end is a vacuum tube connection end, which is close to the flange. The stainless steel inner tube 1 is covered with two layers of corrugated tubes 2, and the space between the two layers of corrugated tubes 2 is filled with an airgel layer 4. The rest of the stainless steel inner tube 1 is covered with a stainless steel outer tube 5, and the stainless steel outer tube 5 and the stainless steel inner tube 1 Airgel layers 4 are filled in between. The airgel layer 4 has better thermal insulation effect. The stainless steel outer tube 5 is seamlessly welded to the junction of the outer corrugated tube 2 , and the outer port of the corrugated tube 2 and the outer port of the stainless steel outer tube 5 are sealed and connected ...
