Description

Metallized carbon fiber heating wiring device, application and wiring method Technical Field The invention relates to the technical field of installation of electric heating equipment, in particular to a metallized carbon fiber heating wiring device, and an application and wiring method thereof. Background In the field of electrothermal conversion, heating elements manufactured by using a resistance heating principle are widely used. Currently, the main current resistance heating element is mainly based on two types of materials, namely a metal heating wire and a pure carbon fiber heating element. In order to ensure electrical safety and use reliability, an insulating layer is generally sleeved on the periphery of the heating element, so that a long heating wire bundle is formed. When in field installation, the heating wire harness is arranged on the loading body according to a preset path, then the loading body is installed and fixed, and the end part of the heating wire harness is connected to the power supply circuit to form a closed loop. When the electric energy is electrified, the electric charge flows in the metal heating wire or the pure carbon fiber heating body to be blocked, and the electric energy is converted into internal energy and heat radiation, so that the electric energy generates heat. In order to achieve uniform heat distribution in the target area, the heating wire harness may be routed in a wound form along the loading body. The common construction mode is that a plurality of fixing pieces distributed in a winding form are arranged on a loading body, and a worker pulls a heating wire harness to enable the heating wire harness to be laid along the plurality of fixing pieces in a sequential winding mode, namely the heating wire harness needs to pass through the plurality of fixing pieces. This arrangement requires the heating wire strands to be sequentially pressed through the plurality of fixing members, and friction force is generated between the heating wire strands. After the heating wire harness bypasses a certain length along a plurality of fixing pieces, the bending parts formed by the heating wire harness are more, frictional resistance can continuously accumulate along the way, so that traction force requirements are increased, and pulling, tensioning or fine adjustment of the later-stage heating wire harness becomes difficult. And too much friction between the heating wire harness and the fixing piece during pulling also easily causes abrasion of the insulating layer of the heating wire harness, so that potential safety hazards are left. In view of this, we provide a metallized carbon fiber heat-generating wiring device, and applications and wiring methods.
