The electric heating pipe has the advantages of small thermal inertia, high temperature control precision and good heating effect, and can intensively generate a large amount of heat energy in a tiny range, so that the electric heating pipe can heat at a high speed, thereby easily reaching a preset temperature and quickly finishing the work of deicing and defrosting. The chassis 1 is divided into a plurality of areas, and each area is provided with one heating device 2, for example, the chassis 1 is divided into four areas, and each area is provided with one heating device 2.
