As shown in the figure, when a small amount of energy is supplied to the fluid to pass through the heater portion to obtain high thermal energy, the length of the flow path is increased and the passage time is increased to obtain high fluid energy.

In order to obtain a large amount of fluid, the fluid introduced into the fluid inlet opens the first electromagnetic opening / closing valve 330 formed on the upper part of the upper first partition 330, flows into the lower collector pipe 210, The third electromagnetic opening and closing part 370 formed in the second partition 420 is opened and the water introduced into the upper collecting pipe 220 through the heater part is formed so as to be able to discharge a large amount of water quickly to the fluid outlet 160 .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view illustrating a heating device of an induction boiler according to the present invention. As shown in the figure, a discharge port 203 for discharging a fluid heated to the upper part of the housing 201 having a cylindrical or quadratic columnar structure is provided, and an inlet 203 for injecting a circulating fluid is provided in the lower part of the housing 201 And a wiring line 207 for guiding the wiring of the induction coil installed inside the housing 201.

A mounting bracket 209 for mounting the induction heating device 200 is provided on the side of the housing 201.

An induction coil for magnetic induction is provided at an inner center of the housing 201, and a heat storage portion is formed at an outer periphery of the induction coil. Therefore, the fluid introduced through the inlet 205 is supplied through the inner circumferential space of the induction coil, and then discharged to the outlet 203 through the heat storage unit provided in the outer circumferential space of the induction coil.

In this process, the fluid is heated by the magnetic induction of the induction coil, and heating of the fluid is accelerated in the heat accumulating portion. Accelerating the fluid heating is to increase the temperature of the fluid rapidly during the initial process and to maintain the latent heat of the fluid. That is, activation of water molecules by magnetic induction is induced to increase the temperature of the fluid, and heat energy that is latent in the heat storage portion can be continuously supplied in the process of heating the inside of the heat storage portion.

The heat storage unit accelerates the heat storage of the fluid passing through the heat storage unit by using a material having a high thermal expansion coefficient and a high thermal conductivity. That is, even if the power of the induction heating apparatus 200 is interrupted for a long time, for example, for 4 to 5 hours, the heat storage unit temporarily generates a heating phenomenon while the fluid introduced through the inlet 205 is discharged through the outlet 203 do. This provides an effect of rapidly raising the temperature of the fluid at the start of the induction heating device 200. [

Such a heat storage portion is made of magnesium oxide (MgO) powder having high melting point, high basic resistance and electrical insulation, high thermal expansion coefficient and high thermal conductivity. It is preferable that magnesium oxide and sand are mixed and loaded in the heat storage portion, and magnesium oxide is loaded in an amount of 5 wt% to less than 10 wt%. This is because the weight of the magnesium oxide is very low, so that there is a problem of sintering and generation of residual chlorine when the magnesium oxide is 10 wt% or more. When the amount of magnesium oxide is less than 5% by weight, the heat storage function is weakened and the energy efficiency is lowered.

The magnesium oxide used in the present invention has a purity of 99.8% and a low purity, and impurities such as CaO, SiO 2, AI 2 O 3, Fe 2 O 3, and B 2 O 3 are present, and such impurities lower the high temperature strength. The lowering of the high temperature strength means that the heat storage efficiency can be lowered because it relates to the heat storage. However, in the induction heating apparatus 200 applied in the present invention, the purity of the magnesium oxide is increased so as to eliminate the heat accumulating effect which is unlikely to increase, thereby lowering the production cost. If the purity of the magnesium oxide is increased as required, the loading ratio of the magnesium oxide may be changed.

In addition, the magnesium oxide is mixed with the sand in powder form to increase the surface area of the magnesium oxide to enhance the heat storage effect, and the powder diameter of the magnesium oxide is preferably approximately 1 mm or less.

3 is a cross-sectional view illustrating an operation principle of the induction heating apparatus 200 according to the present invention. The cross section of the induction heating device 200 may be somewhat changed depending on the capacity of the induction coil, but the structure in which the heat storage portion is provided as the outer circumferential space of the induction coil will remain unchanged.

The induction coil 301 is wound around the outer circumferential surface of the installation pipe 303 having a hollow structure and communicated with the inlet 205 to the lower portion of the installation pipe 303, And a first accumulating portion 305 is provided between the induction coil 301 and the mounting cover 309. The first accumulating portion 305 is disposed between the induction coil 301 and the mounting cover 309, And a second heat accumulating portion 307 is formed between the housing 201 and the mounting cover 309 to receive the mounting cover 309. The second heat accumulating portion 307 is disposed between the housing 201 and the mounting cover 309, So that the fluid introduced through the first accumulator 305 and the second accumulator 307 is discharged to the outlet 203.

In addition, the separator 311 may include a separator 311 to prevent the heat storage material stored in the first accumulator 305 from being discharged through the installation tube 303.

As described above, the first storage portion 305 and the second storage portion 307 are mixed with magnesium oxide and sand, and the magnesium oxide is loaded from 5% by weight to less than 10% by weight. In addition, the purity of the magnesium oxide is approximately 99.5% to 99.9%, preferably 99.8%.

The second heat accumulating portion 307 according to the present invention has a structure in which the second heat accumulating portion 307 is separated from the first heat accumulating portion 305 by the mounting cover 309, The influence of magnetic induction may be insignificant. However, the energy stored in the first heat accumulating unit 305 is transferred to the second heat accumulating unit 307 to increase heat storage efficiency. It is possible to maintain only the first heat storage portion 305 by excluding the heat storage material loaded on the second heat storage portion 307 as needed. Particularly, in the case of a small-capacity induction heating device, only the first heat storage portion 305 can be formed without the second heat storage portion 307.

Since the induction coil 301 is a base device for generating heat by magnetic induction, when the coil is wound on the outer circumferential surface of the installation tube 303, its efficiency is lowered. Therefore, in the present invention, Thereby eliminating the gap between the coils. That is, since the gap between the coils is formed in the winding process of the induction coil 301, the magnetic field is canceled when the magnetic field is diverged by the magnetic induction, and the efficiency of the magnetic induction is lowered.

Therefore, in the present invention, after the induction coil 301 is wound by the installation tube 303, the wound coil is pressed and compressed to remove the gap between the coils. 4, after the induction coil is wound on the outer circumferential surface of the installation tube 303, the induction coil is drawn between the two plate-like pressurizing devices to press the two plates upward and downward, and at the same time, The above process is repeated to wind the induction coil.

Here, the pressing force and the feeding speed of the plate-like pressing device are different depending on the coil material and the diameter, and may be assumed to be an empirical value for pressing the coil to remove the inter-coil gap. In addition, it is preferable that the induction coil 301 is wound on the outer circumferential surface of the installation tube 303 and then the glass fiber coating is performed to remove the inter-coil gap of the induction coil.

The glass fiber coating may cause a gap between the coils even when the induction coil is pressurized. The coiling is minimized by performing glass fiber coating at each winding of the coils, thereby removing the coil vibration. Such a glass fiber coating uses a conventional coating agent to increase the moisture-proofing effect of the induction coil 301 having a large electrical influence and to prevent the occurrence of inter-coil gap due to heat generation of the winding coil.

FIG. 5 is a view showing boiler test operation data using the induction boiler heating device according to the present invention, and FIG. 6 is a sheet showing test operation data of a third party electric boiler.

First, the test according to the present invention was an induction boiler, and the fluid temperature was measured in 12KW capacity, 610 liters of fluid and 5 minutes in 1 hour. The temperature of the tank was measured at the central temperature of the tank. The temperature of the tank was assumed to be the reference temperature for the experiment equality, as the system structure of the electric boiler and the induction boiler were different.

The induction boiler according to the present invention started at an initial temperature of 37.6 ° C and was measured at 59.5 ° C at the end of the test, and the wattage per second increased from 864.7W to 11.7KW. This is because the induction coil 301 of the induction heating device used as the induction boiler of the present invention uses only 12KW of capacity.

On the other hand, the electric boiler used for the experiment was 7.5 KW dedicated to measure the thermal efficiency between the electric boiler and the induction boiler of the present invention with the highest efficiency among the electric boilers. The fluid capacity of the electric boiler was 408 liters, the initial temperature was 35.7 ° C, and the temperature of the fluid rose to 50.2 ° C at the end of the experiment.

Of course, the electric boiler and the induction boiler according to the present invention should have the same capacity, but there is no boiler of the same capacity, and an experiment by separate production causes a problem of deteriorating the efficiency of the product. Therefore, the best efficiency 7.5 KW boiler among the electric boilers sold and the 12 KW induction boiler which is the most commercially available product according to the present invention are compared. Of course, in measuring the efficiency of thermal energy, the capacity of the boiler will not be a problem.

Fig. 7 is a sheet summarizing each experimental data. The efficiency of the boiler corresponding to a substantial temperature rise was calculated. The calculation formula for the boiler efficiency is calculated based on the programmed calculation formula based on the control screen shown in FIG. That is, the conventional efficiency calculation method is applied based on the power consumption, the temperature change, the fluid capacity, and the time corresponding to the induction heating device (located in the center of the screen) of 12 KW capacity based on the tank central temperature of the monitor screen.

As can be seen, the initial temperature of the induction boiler of the present invention increased to 40.0 ° C after 5 minutes at 37.6 ° C, and the efficiency of the boiler was calculated to be 14%. On the other hand, the electric boiler started at 35.7 ° C and after 5 minutes it was 37 ° C, and the electric boiler efficiency was calculated as 8%. After 10 minutes, the efficiency of the induction boiler was measured as 49%, while the efficiency of the electric boiler was measured as low as 15%.

The reason why the efficiency of the induction boiler according to the present invention is calculated at an early stage is that power is supplied to the induction coil 301 and heat energy is accumulated in the first accumulator 305. The temperature of the fluid supplied to the first storage unit 305 is increased during circulation and heating of the fluid by the pump, and it is understood that the storage efficiency is high. On the other hand, the electric boiler maintains the efficiency of 15% for 10 minutes because the energy efficiency is very low in the circulation process and heating process of the fluid, and it is judged that the heat storage function does not exist.

In the induction boiler according to the present invention, the efficiency of the boiler is indicated to be 109% at the point of 25 minutes after starting, and the electric boiler is maintained at 36%. This is due to the continuous supply of energy stored during the continuous circulation of the fluid, which continuously reduces the difference between the storage temperature and the actual temperature of the fluid.

In the present invention, when the boiler efficiency is more than 100%, it is not a violation of the energy conservation law. Instead, the efficiency is calculated by measuring every 5 minutes, and the energy of the heat storage portion is received in the process of calculating based on the present temperature and the initial temperature Because. However, even in this calculation method, the electric boiler to be prepared was also experimented under the same conditions, and it was made according to a general calculation formula.

On the other hand, at 60 minutes after the experiment, the fluid temperature of the induction boiler according to the present invention was 59.5 ° C, the fluid temperature of the electric boiler was 49.3 ° C, and the energy efficiency of the induction boiler was calculated as 129% , Electric boilers were calculated as 86%. That is, in the present invention, a temperature rise of 21.9 ° C is induced by heating 610 liters of fluid at 12KWh for 1 hour, and a 408 liters of fluid is heated at 7.5KWh for 1 hour to induce a temperature rise of 13.6 ° C Respectively.
