Description

[0001] Eddy current induction heating equipment [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heating device for generating warm air, hot water or steam using an eddy current, and more particularly, to a heating device using a plurality of ring-shaped permanent magnets in which N- and S- And is a eddy current induced by the rotation of the permanent magnet due to the driving of the rotor to generate heat of a metal pipe formed around the rotor and to heat the water introduced into the water pipe to provide hot air, hot water, or steam And more particularly to an eddy current induction heating device which minimizes the input energy for driving the rotor.

Generally, most of the devices that make steam such as hot air fan, water heater, etc. supply hot water and warm air using briquet, gas or light oil. When boiling water or air by burning such fossil fuels, Causing energy efficiency problems.

Efforts to reduce the use of fossil fuels are also found in the Kyoto Protocol, an international agreement on global warming regulation and prevention. According to the Kyoto Protocol, developed countries (38 countries) average 5.2% Of greenhouse gases.

Korea is also not free from the Kyoto Protocol, and Korea is highly likely to become a target country for second obligation reduction, and it is expected to reduce greenhouse gas emissions by 2013 ~ 2017

To reduce the use of such fossil fuels, technologies have been developed that transfer energy sources used in homes, companies, factories, etc. from depleted fossil fuels to de-petroleum energy such as solar energy and solar energy, In addition to technologies to burn fossil fuels, boiling technology has developed various technologies that convert electrical energy into thermal energy as it is.

Electromagnetic induction heating is a typical technique. Typically, a heating device for a boiler using high frequency induction heating (registration number: 20-0405016) can be mentioned. However, since induction coil, insulation, and heating tube are inserted into the heating unit to heat the heating tube to boil the water, problems such as the premixed water and the water entering the inlet pipe cause energy consumption There is a problem that the efficiency is very low.

Another technology is "a heat generating device using a high frequency induction coil and a manufacturing method thereof (Publication No. 10-2011-0089945)". However, this technique is based on the fact that induction current flows in the induction heating coil, There is a problem in that energy loss is very high in the process of transferring the heat of the metal pipe to the hollow portion and the energy efficiency is very low due to the technique of boiling water flowing in the hollow portion of the pipe.

Also, as a technique using induction heating, there is a "high frequency induction heating type electric boiler (registration number: 10-0827468)". This technique contains a technical idea of fixing the induction coil to the bobbin and heating the heating body by induction current. However, due to the space in which the hot water and the cold water are mixed with each other and flowed without directionality by the heating body contained in the heating cylinder, The energy efficiency is low and the temperature of the water discharged to the drain port is not uniform as in the case of 'heating device for boiler using high frequency induction heating (registration number: 20-0405016)'.

As another technique, 'electric boiler using induction heating (Publication No. 10-2004-0041130)' uses a method in which an internal core is induction-heated by an eddy current when power is applied to a coil, but an electromagnetic field But also lost to the outside, resulting in low energy efficiency.

As a result, it has been proved through various studies that the heated technique is similar to the conventional method using heat resistance by induction heating using an eddy current, and in particular, the eddy current is generated by using a permanent magnet, Have been proposed by various researchers.

Examples thereof include a permanent magnet type eddy current heating device, which is disclosed in Korean Patent Registration No. 554218 entitled " Energy Conversion Using Rotational Force ", Japanese Unexamined Patent Publication No. 2005-174801, and " Induction Heating Device Using Magnet ", Korean Patent Application No. 2010-22802, And is composed of a rotor and a magnet array made of permanent magnets, which are basic components of the heat generating device, and a heat generating metal made of a cylindrical shape.

However, the above-mentioned conventional devices have a problem that a large amount of input energy is required to drive a rotor made of a permanent magnet.

This is because when the magnetic flux is alternated in the conductor, the eddy current is induced and heat is generated by the joule heat, but at the same time, the force which obstructs the movement of the magnetic flux acts strongly. It is the eddy current brake that utilizes the disturbing force.

Therefore, in order to induce heat generation using an eddy current, it is necessary to overcome the braking force generated by the eddy current and to drive the rotor, so that a very large amount of energy is required.

This fact is reflected in the recently published academic paper entitled "Development of Heat Exchanger Using Eddy Current" (Journal of the Korean Society of Mechanical Engineers, Vol. 33, No. 8, Aug. 28, 2009 (Aug. 2009) pp.565-572 1226-4881 KCI) In the above paper, the thermal efficiency of the heater manufactured by using the electric motor as the power source was measured to be 94.8 ~ 99% between 118 ~ 230 rpm RPM.

The fact that the thermal efficiency of a heater using an eddy current is similar to that of a general electric heater using thermal resistance means that the amount of input energy required for a heater using an eddy current is the same as the amount of electric energy for converting an ordinary electric heater to thermal energy.

Therefore, heaters using eddy currents are comparatively simple devices, and they are inferior in competitiveness to heaters that can be converted into heat energy.

In the above-mentioned paper entitled " Development of a heat generator using eddy currents ", the measured RPM does not exceed 230, and the Korean patent application No. 2010-22802, entitled " There was a problem that the cylindrical heating element and the entire system were severely fluctuated.

As a result, although the existing technology has to minimize the brake force generated by the eddy current, it can not overcome it, and thus there is a problem in development of economical and efficient technology.

(Practical Literature 0001) Korean Utility Model Registration No. 20-0405016 Korean Patent Publication No. 10-2011-0089945 Korea Patent No. 10-0827468 Japanese Patent Application Laid-Open No. 2005-174801
