Description

Induction heating device using magnetic.

The present invention relates to a heating device for producing warm air, hot water or steam by using a magnet, and more particularly, to drive a rotor made of a permanent magnet by using power, and a metal configured around the rotor by rotation of the permanent magnet. In particular, the present invention relates to an induction heating apparatus using a magnet that provides hot air, hot water, or steam by using copper or aluminum metal having high thermal conductivity as a heat exchanger.

When the magnetic field (or the magnet 20) approaches the conductor 10, the conductor generates hysteresis loss and eddy current loss, and Joule heat is generated.

In particular, ferromagnetic materials that adhere well to magnets have higher resistance and Joule heat increases. Iron loss generated from generators, motors, and transformers is a representative example of induction heating by magnetic fields.

Since the iron loss is the main cause of lowering the thermal efficiency of generators, motors, transformers, etc., the use of a stratified iron core or an amorphous iron core with little eddy current is used to reduce the iron loss, but iron loss reduction remains a major problem. .

9 is a basic structure in which iron loss occurs in a conventional generator or transformer.

Iron loss in the structure is proportional to the square of the current and resistance since Joule heat is a base, and a metal with high resistance, that is, steel, nickel, nichrome wire, etc. Heat is also generated in metals such as copper, aluminum, and silver.

In general, iron loss is a combination of hysteresis loss and eddy current loss, and it is known that hysteresis loss is responsible for 70% of the total iron loss and eddy current loss is responsible for 30% of the total iron loss.

Therefore, the iron loss is basically proportional to the square of the magnet density of the rotor and the square of the frequency, so that the larger the size of the rotor, the higher the RPM of the rotor, and the more the number of magnetic poles constituting the rotor, the heat generation increases by four times. Will be.

On the other hand, it is a conventional high frequency induction heating device to obtain a high temperature instantaneously using the iron loss, a high frequency induction heating device is a device for generating Joule heat to the adjacent conductor by using an induction coil that generates a high frequency of 20khz instead of a magnet In order to obtain high Joule heat, it is generally used for metal materials with high resistance, that is, steel, nickel, nichrome wire, etc., and high frequency of 60khz or higher should be used to generate Joule heat for copper or aluminum metal with low resistance.

At present, high frequency induction heating devices are mainly used in electric boilers or induction, and are widely used in various industries such as metal heating and partial heating, but the heat conversion efficiency is 50%, which is more significant than the heater method having 95% or more heat conversion efficiency. Since it is known to be low, there is a need for a technology for providing an induction heating device with high heat conversion efficiency.

Therefore, the present invention has been proposed in view of the problems of the prior art as described above, but an object of the present invention is to apply the principle of induction heating by a magnetic field, but does not generate heat at high frequency by using resistance, and has high current conductivity. The electrical resistance is to provide a heat generating device having a very high heat conversion efficiency because it can be used as a heat exchanger by heating low aluminum or copper metal.

In the present invention, the energy conversion efficiency is particularly high when the magnet part constituting the rotor is used as a permanent magnet having a high magnetic flux density. This is because the heating value of the heating element metal is the highest compared to the input energy when driving the rotor composed of permanent magnets.

Another object of the present invention is to produce a hot water or steam by heating the liquid obtained by forming a liquid receiving space or a liquid passage in the metal when the heating element metal is used as aluminum or copper metal, and the steam produced at this time drives the generator turbine The purpose is to drive the engine by generating electricity or supplying it to the steam engine.

Induction heating device using a magnet of the present invention to achieve the problem to be solved by the present invention is a rotating shaft; A magnet part formed on the rotation shaft and having at least one pair of N poles and S poles alternately arranged; The magnet part is formed in the inner space, the heating element is formed to be spaced apart from the magnet portion; formed, including, in particular, formed of any one of copper or aluminum, a metal having a high thermal conductivity of the heating element metal directly used as a heat exchanger It is characterized by.

The induction heating apparatus using the magnet according to the present invention is an induction heating method using a permanent magnet, but not a high frequency induction heating method which requires the use of magnetic field induction.

In addition, the use of paramagnetic copper or aluminum as the heating element metal has no merit with the rotor made of permanent magnets, and there is no load at initial start-up.The above metal has high thermal conductivity and can be used directly as a heat exchanger without a separate device. Can be.

The induction heating device using the magnet of the present invention becomes a hot air fan when air passes through the heated heating element metal, and when the water is heated or produces steam with the heating element metal, it becomes a boiler.

Therefore, it can provide the side effect that the range of application is extended.

In addition, by forming a liquid receiving space or a liquid passage in the heating element metal to supply the steam generated by heating the liquid obtained to the generator turbine, or to supply the steam engine to provide power to drive the engine to provide a wide range of steam It becomes usable.

In addition, it is possible to produce hot water or steam by heating the liquid obtained by forming a liquid receiving space or a liquid passage in the heating element metal, wherein the produced steam is generated by driving a generator turbine or supplying a steam engine to the engine. By providing the driving power, steam can be used extensively.
