Electro-magnetic induction heating device

Abstract

The invention relates to an electro-magnetic induction heating device. An electro-magnetic induction control circuit controls a heat conduction device, the heat conduction device comprises a casing which is a cylindrical sealed empty cavity, the centers of the upper bottom and the lower bottom of the empty cavity are respectively provided with fitting interfaces, and the empty cavity is separated by an upper partition plate and a lower partition plate into heat conduction oil chambers. Spaces of the upper end and the lower end inside the casing are water chambers. The electro-magnetic induction control circuit comprises two electro-magnetic control plates and two groups of electro-magnetic heating coils, wherein the electro-magnetic heating coils are formed by winding mica insulation leads. The electro-magnetic induction heating device adopts the heat conduction device with a novel structure and enables heat conduction oil which does not flow in the heat conduction oil chambers to be heated directly, the heat conduction oil is a relatively stable heat source, then heat is transmitted to flowing circulation water through a oil-water heat exchanging mode to achieve heating, heat dissipating capacity is reduced to the most extent, and accordingly energy consumption is reduced.

Description

technical field [0001] The invention relates to electric heating equipment, in particular to an electromagnetic induction heater and its realization method. Background technique [0002] Electric heating is a high-quality, comfortable and environmentally friendly heating method that converts clean electrical energy into heat energy. At present, resistance wire / quartz heating is more common in the electric heating method of electric heating devices. However, resistance wire / quartz heating has low thermal efficiency and many other disadvantages. This heating method mainly relies on contact conduction to transfer heat energy. Only one surface of various heating plates and rings made of resistance wires touches the parts that need to be heated, which causes a large part of heat energy to be dissipated in the air. . Theoretically speaking, half of the heat is transferred inside and outside the traditional heating circle, so we say that 50% is dissipated in the air. Of cours...

[0004] Electromagnetic induction heating products have the characteristics of high thermal efficiency, no radiation, and long life. Eddy current generates heat. However, since the cold water circulates in the circuit, it takes a long time for the water in the heating circuit to turn from cold to hot to a certain temperature. To keep the temperature of the water in the circuit constant, more complicated temperature control is required. device realization
