A built-in electromagnetic heating device and heating method

Abstract

The invention relates to a built-in type electromagnetic heating apparatus and heating method. The apparatus comprises a working medium container, electromagnetic heating coils and a power supply circuit, wherein a through hole penetrating through a pipeline is formed in the working medium container; the working medium container after the through hole penetrates through the pipeline is a container with a sealed structure; a working medium is stored in the working medium container; the electromagnetic heating coils are built in the working medium container; the electromagnetic heating coils are wound around the outer surface of the partial pipeline in the working medium container; the electromagnetic heating coils are connected with the power supply circuit; the power supply circuit is led out of the working medium container; the connection and isolation of the working medium in the working medium container and a working medium in the pipeline are controlled through a switch; and the electromagnetic heating coils heat the working medium in the pipeline, and directly or indirectly heat the working medium stored in the working medium container. According to the heating apparatus provided by the invention, the electromagnetic heating coils can directly or indirectly heat the working medium stored in the working medium container, so that the tube pass of the circulation pipeline is shortened, the thermal loss in the conveying circulation pipeline is lowered, the safety and reliability are improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of heating and heating, in particular to a built-in electromagnetic heating device and a heating method. Background technique [0002] At this stage, electric heating has gradually replaced the traditional heating methods such as firewood, charcoal and coal, which have serious environmental pollution and high safety hazards, and become the mainstream heating technology due to its convenience and environmental protection. The heating and heating system using electric heating and heating can be deployed in any place with heating demand without being restricted by environmental conditions, especially suitable for places with large spaces. It only uses and consumes environmentally friendly electric energy of non-polluting substances, so It has been widely promoted and applied. At present, the widely used heating system usually adopts the circulation pump to drive the high-temperature circulating fluid to circul...
