Description

Technical Field

[0001] This utility model relates to the field of electromagnetic heating, and in particular to an electromagnetic air heater structure. Background Technology

[0002] With the development of industry and agriculture, technologies such as hot air circulation drying, vacuum drying, and airflow drying have been developed. Heating methods include finned electric heating tubes, circulating hot water, steam, thermal oil, and heat pumps. The disadvantage of these technologies is the separation of the heat source and the material, requiring an intermediate medium (such as air or water) to transfer heat between the heat source and the material being dried. This method has theoretical flaws because as the heat transfer medium passes through the material, the material continuously absorbs heat, and the medium temperature gradually decreases, creating a temperature difference between the front and back ends of the material (if there is no temperature difference, it means the material has not absorbed heat, and the drying process cannot be achieved). This temperature difference leads to a large difference in drying time between the front and back ends. The front end material is over-dried, losing too much water, while the back end material has too much moisture, making it difficult to accurately control the moisture content, reducing product quality, requiring constant rewinding, resulting in a large workload and wasted energy. Electromagnetic heaters are currently the most widely used heating method in industrial and civilian equipment. They eliminate the hazards and interference of open flames during the heating process, using an electromagnetic field to create eddy currents on the surface of the workpiece for heating. The existing electromagnetic air heater structure has a linear heat flow channel structure with electromagnetic coil layout, which results in rapid energy dissipation and low concentrated heat energy storage performance. Utility Model Content

[0003] The purpose of this invention is to provide an electromagnetic air heater structure that solves the problem of rapid energy loss diffusion in existing linear heat flow air duct structures.

[0006] An installation connection frame assembly is provided between the electromagnetic feeder housing structure and the movable base.

[0007] The insulation material layer is an insulation cotton layer.

[0008] The beneficial effects of this invention are as follows: The electromagnetic coil that generates the magnetic field in this electromagnetic air heater structure is located on the outer surface of the bent hot air duct. When a high-frequency current passes through the electromagnetic coil, eddy currents are generated in the hot air duct, achieving uniform heating and concentrated energy discharge. The hot air duct can be multi-layered with large-area uniform heating and can be made into any shape; the heat of the electromagnetic coil plate is also utilized, thus saving energy.
