Abstract

The invention discloses an electric heater with low electromagnetic radiation. The electric heater comprises a tube body, a U-shaped electric heating wire arranged in the tube body, and a cold needle connected with the two ends of the U-shaped electric heating wire; one end of the cold needle protrudes outside of the tube body via one end of the tube body, and the other end of the tube body is closed; and the direction of rotation of coils in the U-shaped electric heating wire is consistent. The electric heater with the low electromagnetic radiation provided by the invention solves the problem that electromagnetic radiation of electric heaters in the prior art is higher.

Description

technical field [0001] The invention relates to the field of electric heaters, in particular to an electric heater with low electromagnetic radiation. Background technique [0002] Electric heating products widely exist in our daily life, and the most common application is the armored electric heating technology. The principle is to install the electric heating wire in the metal tube, and fill the insulating material between the heating wire and the metal tube. When working, a working voltage is applied to both ends of the resistance wire, and the resistance wire generates heat W=I 2 R, heat is transferred to the metal outer tube by thermal conduction. [0003] From the principle of magnetic induction of current, it can be known that current can induce electromagnetic field, and there is a continuous magnetic field around the metal tubular electric heating tube. The direction of the magnetic field changes with the direction of the current, and the strength of the magnetic f...
