An electromagnetic induction heating plate with uniform surface temperature

Abstract

The invention relates to an electromagnetic induction heating panel uniform in surface temperature, and can effectively solve the problems of high power consumption and poor temperature uniformity of existing equipment. The invention adopts the technical scheme that the heating panel comprises a housing, a metal panel, an upper thermal insulating layer, magnetic pillars, a magnetic material layer, a lower thermal insulating layer, induction coils and an intermediate-frequency power supply; the housing is of a hollow structure which is made of a nonmagnetic material and of which the upper part is open; the lower thermal insulating layer is arranged at the bottom inside the housing; the magnetic material layer is arranged on the lower thermal insulating layer; the magnetic pillars uniformly distributed are arranged on the magnetic material layer; the upper thermal insulating layer is arranged on the magnetic pillars; the metal panel is arranged on the upper thermal insulating layer; and the induction coil is arranged outside each magnetic pillar. The electromagnetic induction heating panel disclosed by the invention is novel, unique, simple, reasonable, easy to operate, low in cost, high in uniformity of the surface temperature, high in heating efficiency and low in energy consumption, and is an innovation on the electromagnetic induction heating panel.

Description

technical field [0001] The invention relates to heating equipment, in particular to an electromagnetic induction heating flat plate with uniform surface temperature. Background technique [0002] Electromagnetic induction heating is to use the conversion between electricity, magnetism and heat to achieve the effect of heating the heated object itself. Electromagnetic induction heating has been widely used in industry and life fields, such as induction cooker, drying equipment, curved plate forming of large ship hull, production of seamless steel pipe for bearing, rapid heating of local surface of workpiece and other application fields. Many scholars at home and abroad have conducted a series of studies on heating mechanism, theoretical modeling, electromagnetic thermal coupling, temperature field distribution, etc., and applied them to practical engineering problems, achieving good social and economic benefits. [0003] Electromagnetic induction heating plate is a kind of e...
