Large power carbon fiber electric heating tube for industrial use

Abstract

The invention provides a large power carbon fiber electric heating tube for industrial use, which comprises an outer electrode, electrode packing heads, electric heater bodies, an electrode wire, internal racks, a tubular case, and an exhaust hole. Two or more electric heating bodies are connected in series in the tubular case, an internal rack is disposed between the electric heating body and the tubular case, an internal sleeved tube runs through the electric heating body having electric wire penetrating therein, an internal rack is disposed between the internal sleeved tube and the electric heating body, sleeve shaped electrodes are disposed on both ends of the electric heating body, which are connected with the electrode wire through connection wires. Electrode packing heads equipped with outer electrodes are disposed on both ends of the tubular case, and the electrode wire is connected with the outer electrode through high temperature tolerant metal connection plates. Comparing with technique in prior art, the electric heating tube has uniform working temperature, stable electric heating performance, long life, and heating efficiency reaches over 98%, consequently has great propagation and application value.

Description

1. Technical field [0001] The invention relates to an electric heating tube in electrical equipment, in particular to an industrial high-power carbon fiber electric heating tube used for heating in electrical equipment. 2. Background technology [0002] As we all know, the quartz electric heating tubes in the prior art generally use metal electric heating elements, such as molybdenum wire, tungsten wire and the like. During the electric heating process, the surface of the metal electric heating element is easily oxidized due to high temperature, and there are problems of damage and burnout. Therefore, it is difficult to make the above-mentioned metal materials into a durable and high thermal efficiency electric heating tube, which affects the application range of the electric heating tube to a certain extent. Therefore, in recent years, products with non-metallic carbon fiber as the electric heating body have been more and more widely used, because it not only has high ther...

AI Technical Summary

Problems solved by technology

Metal electric heaters are easy to cause surface oxidation due to high temperature during the electric heating process, and there are problems of damage and burnout. The mission life is short and the thermal efficiency is low; at the same time, the electric energy is converted into light energy, which consumes a lot of power.

Therefore, it is difficult to make the above-mentioned metal materials into a durable and high thermal efficiency electric heating tube, which affects the application range of the electric heating tube to a certain extent.
