Heating tube forming process

Abstract

The invention relates to a heating tube forming process. A heating tube comprises a quartz glass tube, the inside of the quartz glass tube is coated with an electrode silver paste ring which is electrically connected with an electrode collar, a copper wire is welded onto the electrode collar, the head of the copper wire is welded onto a screw, the opening of an electrothermal film carrier is sealed through a seal cover in which a through hole is formed, and screw penetrates the through hole. The heating tube forming process comprises the steps of spraying a heating film, cleaning the glass tube, drying the glass tube, coating sliver paste, solidifying the sliver paste, welding electrodes, assembling the heating tube, testing the heating tube and capping a plastic connector. The film layer of the heating tube is stable within 5000 hours, and the heating tube is highly reliable; an electrothermal film covers the surface of the electrothermal film carrier, so that the heating surface of the electrothermal film is large, the heat transfer effect is good, the warming is fast, and the heat efficiency is high.

Description

technical field [0001] The invention relates to an installation, forming and testing process, in particular to a heat pipe forming process. Background technique [0002] The heating elements of existing electric tea stoves, water heaters, etc. generally use electric heating wires. Because the electric heating wire is a wire heating element, the heating area is small, and the area in contact with the material to be heated is also small, the heat transfer effect is poor, and the temperature rises slowly; The temperature difference of the material to be heated is large, and the heating wire often needs a very high temperature, so that the material to be heated can reach the required temperature. The surface layer of the heating wire is easily oxidized when the heating wire works at high temperature for a long time, and its life is shortened, and the falling oxides will pollute the material to be heated ; The electric heating wire generates heat through resistance, the electroth...
