The length of each carbon fiber heating wire 6 is 12.5 meters, and the carbon fiber heating wires 6 are connected to the internal power supply wire of the compensation type electric heater in parallel end to end. In the embodiment, a carbon fiber material is used as a heating material, carbon fiber heating cables are heating bodies of the carbon fiber electric heater, each heating cable is composed of about 2.4 ten thousand carbon fiber heating wires, the resistance temperature coefficient is small, and the electric-heat conversion efficiency is high; the service life is long, the performance is stable, the safety and the reliability are realized, the temperature distribution uniformity and the comfort in the carriage can be improved, the carriage is clean and sanitary, the energy is saved, and the development direction of environmental protection and energy is met.
