摘要：A method for manufacturing an all-glass solar heat collecting tube without a

tail pipe. The bottom of one end of an inner glass tube plated by a selective absorbingcoating layer is rounded, the other end is connected to a first glass outer tube. Thebottom of one end of a second glass outer tube is rounded and the other end is flared.The connected inner glass tube/first glass outer tube is inserted into the second glassouter tube. A gap is formed between the first glass outer tube and the second glassouter tube to serve as an air exhausting channel. The first glass outer tube is insertedinto the flared opening of the second glass outer tube. The contact point between thefirst glass outer tube and the second glass outer tube is heated to frit seal and butt joint.
