When the electromagnetic wave generator works, alternating current is introduced into the current-carrying conductor, an alternating electromagnetic field is generated around the current-carrying conductor, and the metal magnetizer and the beam-collecting tube are in the alternating electromagnetic field, so that induced electromotive force is generated by cutting magnetic lines of force, eddy current is generated, and electric energy is converted into joule heat.
The number of the electromagnetic heat pipes of the cluster electromagnetic heat pipe is less than that of the existing single-turn electromagnetic heat pipe, so that the welding points between the pipe plate and the heat pipes are reduced, and the welding quality of products is improved.
After alternating current is introduced into the current-carrying conductor, an alternating electromagnetic field generated around the current-carrying conductor is restrained inside the metal magnetizer and the bundling tube, and magnetic lines of force are cut by the metal magnetizer and the bundling tube to generate induced electromotive force, so that eddy joule heat is generated and is conducted outwards along the radial direction of the metal magnetizer and the bundling tube. The metal magnetizer and the bundling tube are both heating bodies and shields of electromagnetic fields, and have double functions of heating and shielding.
The cluster electromagnetic heat pipe is composed of a plurality of electromagnetic heat pipes and a cluster pipe, and is connected into a whole through a left pipe plate and a right pipe plate to form an equivalent potential, so that electromagnetic radiation generated by induced electromotive force can be effectively shielded.
The cluster electromagnetic heat pipe is connected with a superaudio power supply, superaudio vibration is generated on the electromagnetic heat pipe, and impurities in a heating medium are not easy to attach to a metal magnetizer of a heating element; when water is heated, no scale is formed on the metal magnetizer of the heating element, the heat transfer between the heat pipe and the heating medium is effectively ensured, and the long-term safe and stable operation of equipment is fully ensured.
Compared with the existing single-turn electromagnetic heat pipe, the multi-turn electromagnetic heat pipe has the advantages that the heat exchange area is 20-80% smaller, and the heating medium is heated quickly.
