An energy-saving intermediate frequency electric furnace with heat dissipation function

Abstract

The invention discloses an energy-saving type medium-frequency electric furnace with a heat radiation function. The energy-saving type medium-frequency electric furnace comprises a furnace shell. A water tank is arranged on the right side of the furnace shell. An air pump is arranged on the right side of the water tank. A heat exchange circulation pipe is arranged at the top of the water tank. Two fixed plates are mounted at the top of the water tank. The heat exchange circulation pipe is mounted on the fixed plates. A plurality of cooling fins are arranged at the position, located between the two fixed plates, of the heat exchange circulation pipe. A water inlet pipe is mounted at the bottom of the right side of the furnace shell. A water outlet pipe is mounted at the top of the left side of the furnace shell. The end, away from the water outlet pipe, of the heat exchange circulation pipe communicates with the water tank through the top of the water tank. According to the energy-saving type medium-frequency electric furnace with the heat radiation function, heat generated when the medium-frequency electric furnace works can be effectively reduced, the heat radiation effect is better, heat radiation requirements are met, meanwhile, consumption of water resources and electric resources can be effectively reduced, and the use cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of intermediate frequency electric furnaces, in particular to an energy-saving intermediate frequency electric furnace with heat dissipation function. Background technique [0002] The intermediate frequency electric furnace is a power supply device that converts the power frequency 50HZ AC into an intermediate frequency (above 300HZ to 20K HZ). The medium-frequency alternating current flowing through the capacitor and the induction coil generates high-density magnetic force lines in the induction coil, and cuts the metal material contained in the induction coil, generating a large eddy current in the metal material. This eddy current also has some properties of the intermediate frequency current, that is, the free electrons of the metal itself flow in the metal body with resistance to generate heat. [0003] Since the intermediate frequency electric furnace will generate a large amount of heat during opera...
