Electromagnetic heating liner

Abstract

The invention discloses an electromagnetic heating liner, comprising: a small pipe, a middle pipe and a large pipe; a water inlet chamber is formed between the middle pipe and the large pipe; a heating pipe structure is arranged between the middle pipe and the small pipe; the heating pipe structure It includes a first pipeline, an electromagnetic heating coil and a second pipeline. The electromagnetic heating coil is located between the first pipeline and the second pipeline, and is wound on the outer surface of the first pipeline; a second heat conduction coil is formed between the second pipeline and the middle pipeline. The small pipe has a water outlet channel, and both the second heat conduction chamber and the water outlet channel communicate with the water inlet chamber; the inner wall of the first pipe and the outer wall of the small pipe form the first heat conduction chamber, and a plurality of water flow holes are opened on the wall of the small pipe. The water flow hole communicates with the first heat conduction cavity and the second heat conduction cavity. The electromagnetic heating liner of the present invention can maximize the heat generated by the heated pipeline and the electromagnetic heating coil to be taken away by the water flow, thereby improving the service life of the electromagnetic heating coil and the pipeline, and greatly improving the utilization rate of energy.

Description

technical field [0001] The invention relates to a heating inner container, in particular to an electromagnetic heating inner container. Background technique [0002] The principle of electromagnetic heating is to generate an alternating magnetic field through the components of the electronic circuit board. When a ferrous container is placed on it, the surface of the container cuts the alternating magnetic force lines and generates an alternating current (ie eddy current) at the metal part of the bottom of the container. The iron atoms at the bottom of the container move at high speed and irregularly, and the atoms collide and rub against each other to generate heat energy, thereby heating the object. [0003] The existing electromagnetic heating liner often directly wraps the electromagnetic heating coil on the outer surface of the pipeline to heat the pipeline, which will cause the heat of the electromagnetic heating coil to be difficult to dissipate, thereby reducing the s...

Problems solved by technology

[0005] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art, and to provide an electromagnetic heating liner to overcome the fact that the existing electromagnetic heating liner often directly wraps the electromagnetic heating coil around the outer surface of the pipeline to heat the pipeline, resulting in The heat of the electromagnetic heating coil is difficult to dissipate and the heat on the outer surface of the pipeline is not fully transferred to the inside of the pipeline, which reduces the service life of the electromagnetic heating coil and pipeline and the technical defects of low heat utilization
