Embodiment Construction

[0045] As shown in Figure 1, Figure 2, Figure 3, and Figure 4: the outer glass tube 1 of the vacuum heat collecting tube and the inner glass tube 3 of the vacuum heat collecting tube are aligned, and the vacuum heat collecting tube is coated on the inner glass tube 3 of the vacuum heat collecting tube to absorb heat After the film 2 is processed with the outer glass tube 1 of the vacuum heat collecting tube to form a glass tube with one end open and one end closed, a metal spring bracket 13 is installed in the interlayer of the closed end, and the outer glass tube 1 of the vacuum heat collecting tube and the inner glass tube of the vacuum heat collecting tube are installed. The interlayer of 3 is evacuated to form the vacuum chamber 14 of the heat collecting tube.

[0046] The conductive film electrically connects the spring 6, the metal molybdenum sheet 7, the lead wire 8 of the glass package, the electrode connector contact point 9 and the electrode connector 10 to form a con...

Abstract

The one-way or two-way electrostatically antiscale vacuum solar heat collecting tube has one-way vacuum solar heat collecting tube made through conventional steps or two-way corrugated vacuum solar heat collecting tube. The making process of the vacuum solar heat collecting tube includes the steps of making glass sealed electrode, making telescopic glass tube, welding glass, annealing, deairing, etc. The glass sealed electrode is made through either heating and extruding while introducing protective gas or sintering glass bead onto metal wire and secondary smelting to seal in exhausted pipe. The vacuum heat collecting tube has exhaust tail pipe and electrode welded. The two-way corrugated vacuum heat collecting tube has inner tube and corrugated tube. The electrode has one end connected electrically to the heat absorbing film and the other end led out and is provided with electrode protecting sleeve and electrode connector.

Description

technical field [0001] The invention relates to a method for manufacturing an electrostatic anti-scaling solar vacuum heat collecting tube, which belongs to the field of solar energy applications. Background technique [0002] At present, the vacuum heat collection tube is an inner tube coated with a light-absorbing film and one end sealed, and a transparent outer tube sealed at one end. A stainless steel carrier card with a getter is installed at the bottom, arranged concentrically, and packaged together. The open ends of the two tubes pass through The glass lathe is welded together to form a casing with one end fixed and the other end free. After the exhaust is exhausted through the exhaust pipe located at the tail, the glass is welded and sealed to form a glass vacuum heat collector with one end open; or the vacuum heat collector is coated with light The inner tube of the absorption film and the transparent outer tube are arranged concentrically, and they are packaged tog...
