Description

technical field [0001] The invention relates to an infrared heating module, in particular to an infrared plane reflection carbon fiber cable heating module and a preparation method thereof. Background technique [0002] In recent years, electric heating in non-traditional heating areas has developed rapidly. In particular, carbon fiber cables are favored by the market because they use carbon fiber as a heating element, and their electrothermal conversion efficiency is as high as 90% during work, and produce far infrared rays that are beneficial to the human body. . However, the current carbon fiber heating cables have the following problems: [0003] 1) Chinese Patent Publication No. CN104981037A discloses a radiation-proof carbon fiber heating cable, which shields electromagnetic radiation by setting a shielding layer inside the cable. When the carbon fiber is energized, the dimensionless reluctance and magnetic field of the carbon fiber are under the action of Lorentz fo...

AI Technical Summary

Problems solved by technology

After testing by the National Infrared Center, the electric-thermal radiation conversion efficiency of the carbon fiber heating cable in the working state is 30-40%, but after being laid in the concrete environment, its electric-thermal radiation conversion efficiency is only about 15%, so in the concrete environment When working, the carbon fiber cable mainly transfers heat in the form of heat conduction, rather than in the form of radiation, which greatly reduces the efficiency of heat transfer.
