Conduit-type high-frequency electric heater unit, heating device, and heating method

Abstract

The invention provides a conduit-type high-frequency electric heater unit, a heating device, and a heating method, and belongs to the technical field of heating. The conduit-type high-frequency electric heater unit comprises at least a heating tube. The heating tube is made of a magnetic conductive metal material. At least a high-frequency electromagnetic wire passes through the heating tube. The high-frequency electromagnetic wire is connected with a high-frequency power supply. The conduit-type high-frequency electric heater unit, the heating device, and the heating method improve heating speed by using a high-frequency electromagnetic heating method of threading a wire in a conduit. The device and the method are high in working efficiency, wide in application range, and heating is safer and more reliable, service life is longer, energy consumption is reduced, and the device and the method protect environment and have no pollution.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a threaded tube type high-frequency electric heating device, heating equipment and a heating method. Background technique [0002] Heating technology is often used in various mechanical equipment, such as jigsaw machines, boilers, water heaters, etc. The commonly used heating method is mostly combustion heating, that is, coal, wood, gas and other fuels are used for combustion, and then the object to be heated is heated. However, the way of burning and heating consumes a lot of energy and causes serious pollution. [0003] The existing electric heating method can greatly reduce energy consumption and pollution. Among them, the high-frequency electromagnetic heating method is a commonly used heating method. The existing high-frequency electromagnetic heating method is generally to wind the high-frequency electromagnetic wire outside the metal container to form a high-frequency e...

Problems solved by technology

[0004] However, because the existing high-frequency electromagnetic heating method adopts the method of winding coils, when the water outside the metal container needs to be heated, the high-frequency electromagnetic wire wound outside the metal container will be directly immersed in the water, which is likely to cause leakage Dangerous; and, if it is applied to larger equipment, such as a boiler, the high-frequency electromagnetic wire needs to be wound outside the boiler for heating, which not only requires high-frequency electromagnetic wire laying, but also consumes a lot of power and has low heating efficiency

Therefore, the existing high-frequency electromagnetic heating method has a small application range, low safety, high power consumption, and low heating efficiency.
