Problems solved by technology

Although the electrothermal film made in this way already has high electrothermal conversion efficiency, the upper and lower insulating materials are non-transparent non-metallic materials. When the graphene film is wrapped around it, it will still block part of the heat. The far-infrared waves generated when the electrothermal film is energized will also be partially blocked by it, resulting in a partial loss of its conversion rate.

Embodiment Construction

[0019] The specific implementation of the graphene electrothermal film quartz heating tube of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] See attached figure 1 The graphene electric heating film 3 quartz heating tube includes a quartz tube 1 and a mica sheet 2 is fixedly arranged in the quartz tube 1, and a graphene electric heating film 3 is arranged on the mica sheet 2. Terminals 4 are designed at both ends of the graphene electric heating film 3. Terminals 4 at the end extend from both ends of the quartz tube 1 through molybdenum rods 5 and are connected to the power supply.

[0021] In addition to mica sheets, supports such as quartz sheets and ceramic sheets can also be used.

[0022] The mica sheet can be fixed in the quartz tube after being tensioned by the molybdenum rod, or the mica sheet can be fixed on the inner wall of the quartz tube. The graphene electrothermal film can also be directly tighten...

Abstract

The invention relates to the technical field of graphene, and discloses a graphene electrothermal film quartz heating tube which comprises a quartz tube and a graphene electrothermal film arranged inthe quartz tube, terminals are designed at the two ends of the graphene electrothermal film, molybdenum rods are connected to the terminals at the two ends, and the molybdenum rods extend out of the two ends of the quartz tube and are connected to a power supply. According to the invention, the graphene film is arranged in the quartz tube, so that the electro-thermal conversion efficiency of the graphene film is greatly improved, and the far infrared transmission efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of graphene, in particular to a graphene electrothermal film quartz heating tube. Background technique [0002] The general application method of graphene electrothermal film is to encapsulate the graphene film between the upper and lower insulating materials, and then electrify the positive and negative electrodes, and the graphene material converts electrical energy into heat energy. Although the electrothermal film made in this way already has high electrothermal conversion efficiency, the upper and lower insulating materials are non-transparent non-metallic materials. When the graphene film is wrapped around it, it will still block part of the heat. The far-infrared waves generated when the electrothermal film is energized will also be partially blocked by it, resulting in a partial loss of its conversion rate. Contents of the invention [0003] The purpose of the present invention is to solve the abo...
