Zero-radiation high-efficient electric heating energy converter

Abstract

The invention discloses an electromagnetic induction heating device and particularly relates to a zero-radiation high-efficient electric heating energy converter. The zero-radiation high-efficient electric heating energy converter structurally comprises a heating inner cavity and a heating outer cavity, wherein the heating inner cavity is formed by sealing the inner wall of an inner cavity heating pipe, the heating outer cavity is formed by sealing the outer wall of the outer cavity heating pipe and the inner wall of an outer casing pipe, an electromagnetic induction coil is placed between the inner cavity heating pipe and the outer cavity heating pipe, and insulating materials are placed between the inner cavity heating pipe and the electromagnetic induction coil as well as between the outer cavity heating pipe and the electromagnetic induction coil. The electromagnetic induction heating device provided by the invention adopts a structural form of an inner and outer combined heating cavity, under the condition of same power, the volume of the heater can be reduced by a half. Moreover, since the magnetic circuit, except the end part, of the electromagnetic induction coil is completely sealed through heating pipe, magnetic flux loss is avoided, zero electromagnetic radiation is realized, and the electric heating energy conversion efficiency is improved.

Description

technical field [0001] The invention discloses an electromagnetic induction heating device, in particular to a zero-radiation high-efficiency electrothermal energy converter. Background technique [0002] Under the impetus of countries vigorously advocating the use of clean, efficient and renewable energy policies, the traditional thermal energy production methods fueled by coal and oil will be replaced by high-tech thermal energy production methods characterized by high efficiency and energy saving. [0003] Electromagnetic induction heating is to generate high-frequency alternating magnetic field through electromagnetic induction coil, and generate eddy current in the heating body through high-frequency alternating magnetic field to complete electrothermal energy conversion. The existing electromagnetic induction heating devices generally have the problems of electromagnetic radiation and heat loss.

Problems solved by technology

[0005] Since the magnetic strip is discretely assembled outside the coil, it is difficult for the magnetic circuit thus formed to completely seal the leakage of the high-frequency magnetic field; when the high-frequency magnetic field passes through the magnetic strip, the magnetic strip itself will also generate heat, which will cause energy loss; this The structure is bulky and the space utilization rate is low
