Description

Technical Field

[0001] This utility model relates to the field of graphene spraying device for heating cable surface, specifically an automatic graphene spraying system for finned heating cable surface. Background Technology

[0002] Heating cables are an important type of electric underfloor heating system, with advantages such as fast heating speed, stable performance, convenient control, and long lifespan. They play an irreplaceable role in modern life. Heating cables use electricity as an energy source and energize alloy resistance wires or carbon fiber heating elements. The alloy resistance wires or carbon fibers start to heat up and then transfer heat to the floor surface through heat conduction and heat radiation.

[0003] Improving the heat transfer efficiency of heating cables is an effective way to reduce their operating costs. Therefore, a finned heating cable was designed to increase the heat exchange area per unit time. Simultaneously, a graphene coating with a high heat transfer coefficient was applied to the fin surface to further enhance heat utilization. Graphene is a carbon atom-based heating cable... 2 Two-dimensional carbon nanomaterials with hexagonal honeycomb lattice composed of hybrid orbitals allow for rapid heat transfer between atoms. Spraying graphene onto the outer surface of the cable effectively improves the thermal conductivity and radiation capacity of the heating cable, resulting in better heat transfer performance and faster heating.

[0004] Currently, there is no automated device on the market capable of spraying finned heating cables. The surface spraying of finned heating cables is often done by applying graphene to the fin surface. This method is not only too costly, but also results in uneven surface coating and low thermal conductivity. Automated spraying devices are needed for finned heating cables to reduce costs and improve coating accuracy. Therefore, this invention is proposed. Utility Model Content

The system aims to automatically and uniformly coat the outer surface of the heating cable fins, thereby enhancing the heat transfer performance of the heating cable and solving the problem of poor heat dissipation and energy loss caused by the current finned heating cables during actual operation.
