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

The eddy current boiler according to an embodiment of the present invention includes a rotary shaft 110 for transmitting power, a plurality of induction heaters (not shown) formed at regular intervals along the circumferential direction, In the groove 123, two or more disk-shaped rotors 120 in which permanent magnets 125 are arranged alternately in the radial direction of N and S poles, a plurality of disk-shaped rotors 120 spaced apart from the disk- An eddy current heat exchanger (100) including a coil-type heating tube (130) surrounding the heating coil (130); And the left and right support panels 310 and 320 for supporting the eddy current heat exchanger 100 from both sides, wherein the coil-shaped heating pipe 130 is connected to the disk-shaped rotors 120 at a predetermined angle (?).

As shown in FIG. 4, one metal supply pipe is inclined at a predetermined angle? With the disk-shaped rotors 120 so that the permanent magnets 125 are wound around the metal- The braking force according to the rotation of the rotor is reduced by reducing the area intersecting with the coil-type heating tube 130, and the water introduced into the inlet connection tube 132 is heated sufficiently through the coil-type heating tube 130 (In FIG. 1, reference numeral 134 may be used as an inlet connection pipe, and 132 may be used as an outlet connection pipe, hereinafter the same).

At this time, the angle? Between the coil-shaped heating tube 130 and the disk-shaped rotors 120 is preferably 5 to 15 degrees. When the permanent magnet 125 is rotated at a speed less than 5 degrees, there is a problem in that the number of turns of the coils that cross each other when the permanent magnet 125 rotates is small, so that it is difficult to lower the braking force according to the rotation of the rotor. There is a problem that a space to be wasted at both ends of the heating tube 130 becomes large and it is difficult to rotate the disk-shaped rotors 120 on the inner side.

4 to 6, the permanent magnets 125 are disposed in a plurality of grooves 123 formed in the rim of each disk-shaped rotor 120 in a direction parallel to the axial direction of the rotating shaft 110 And the length of the permanent magnet in the axial direction is equal to the outer edge thickness t of the disk-shaped rotor 120 and the outer edge thickness t of the disk-shaped rotor 120 is equal to the thickness of the coil- (Pitch: p) of the center of gravity. This is because the center distance (pitch: p) of the coil-type heating tube 130 is smaller than the center-to-center distance (t) of the annular heating tube 130 in a state where the outer diameter of the metal- When the outer peripheral edge of the disk-shaped rotor 120 is tightly closed to a thickness smaller than the outer edge thickness t of the disk-shaped rotor 120, the braking force due to the rotation of the rotor is difficult to lower.

The coil-type heating tube 130 may be disposed at a distance d of 3 to 7 mm from the disk-shaped rotors 120 in the radial direction. If the distance is less than 3 mm, there is a problem that the heat of the coil-type heating tube 130, which is 150 to 200 ° C, is transferred to the permanent magnet 125 as it is, There is a problem that the efficiency deteriorates.

In this case, the means for disposing the coil-type heating tube 130 at a constant distance d from the disk-shaped rotors 120 may be varied. However, as shown in FIGS. 1 and 2, Three or more fixing rods 140 may be fastened to the left and right support panels 310 and 320 which are inserted and supported from the left and right sides so as to be in contact with the outside of the coiled heating tube 130. 1 and 2, six fixing rods 140 are supported and fixed through the outside of the coil-type heating tube 130. However, at least two of the fixing rods 140 are provided on the outer side of the coil- It is enough. Preferably, at least one of the three or more fixing rods 140 has a means for adjusting the inner radius formed by the three or more fixing rods 140. For example, a long groove (not shown) is formed in the left and right support panels 310 and 320 to which the fixing rod 140 for adjusting the inner radius is fastened, toward the rotary shaft 110, So that both ends of the bolt 140 are inserted and fastened by the bolts 142.

As another example of arranging the coil-shaped heating tube 130 at a constant distance d from the disk-shaped rotors 120, as shown in FIG. 16, The left and right support panels 310 and 320 can be supported through the inlet connection pipe 132 and the outlet connection pipe 134 connected to the left and right support panels 310 and 320, respectively. Although the six fixing rods 140 are shown together in FIG. 16, only the inlet connection pipe 132 and the outlet connection pipe 134 pass through the left and right support panels 310 and 320, ) May be fixed.

As shown in FIGS. 1 and 2, a plurality of spacing rods 200 are separately fastened between the left and right support panels 310 and 320 so as to maintain a predetermined gap between the left and right support panels 310 and 320. [ However, the above-described three or more fixing rods 140 may replace the role of the spacing rods 200.

The rotation shaft 110 is inserted and supported through the through holes 312 and 322 formed in the left and right support panels 310 and 320 as shown in FIG. It is preferable that bearing members 330 and 340 are further inserted into the through holes 312 and 322 and both ends of the rotating shaft 110 are inserted and supported in the bearing members 330 and 340.

5 and 6, the rotor having the conventional permanent magnet is divided into a plurality of disk-shaped rotors 120 and inserted into the rotary shaft 110 at regular intervals, So that it is easy to carry and replace parts, and heat transfer is facilitated by the disk-shaped rotor body 122 or the like, so that the life of the permanent magnet 125 can be increased. Here, as shown in FIG. 11, one or more air blowing through holes 122a are formed in each of the disk-shaped rotor bodies 122 so as to effectively remove the heat of the disk-shaped rotor body 122 and utilize the heat for heating or the like .

The permanent magnets are roughly divided into ferrite magnets, AlNiCo magnets, and rare earth magnets. Ferrite magnets include barium ferrite (BaFe) and strontium ferrite (SrFe) Has a higher coercive force (Hr) than an alnico magnet, but has a lower residual magnetic flux density (Br). The rare-earth magnets include a samarium cobalt (SmCo) magnet and a neodymium (NdFeB) magnet, both of which have higher coercive force and residual magnetic flux density than ferrite magnet and alnico magnet. However, coercivity and residual magnetic flux density It is important to pay attention to high-temperature irreversible potatoes because they have a decreasing property. In particular, neodymium magnets have a higher coercive force and residual magnetic flux density than samarium cobalt magnets, but have a lower temperature dependency and a lower magnetic flux density, which is difficult to use in an environment exceeding 80 ° C and is easily oxidized to require coating treatment .

Therefore, in designing the eddy current heat exchanger 100 with a rare-earth magnet, the temperature of the permanent magnet 125 disposed around the inside of the coil-shaped heating tube 130 should not exceed 80 ° C.

When the permanent magnets 125 are rotated by disposing the disk-shaped rotors 120 so as to be spaced apart by a predetermined distance d from the inside of the coil-type heating tube 130, It is necessary to replace the permanent magnets 125 from time to time as long as the heat is easily transferred into the irreversible potato state due to the hysteresis loss in the permanent magnet 125 and the heat due to the eddy current loss in the magnet, There is a problem.

3, the permanent magnets are cut into a plurality of disk-shaped rotors 120, and the permanent magnets are cut at a predetermined interval (one body) in the longitudinal direction of the rotating shaft, The heat of the permanent magnets 125 attached to the peripheries of the respective rotors 120 is inserted into the rotary shaft 110 so that the heat of the permanent magnets 125 attached to the rotary bodies 122 And then to the outside through the rotary shaft 110. [ According to the embodiment described later, the heat transferred to the rotor body 122 more effectively by the at least one ventilation hole 122a and / or the exhaust fan 160 formed in the disk-shaped rotor body 122 It is possible to solve the problem that the life of the permanent magnet 125 is shortened due to overheating of the permanent magnet 125.

Therefore, it is preferable that the disk-shaped rotary body 122 and the rotary shaft 110 are formed of a material having high thermal conductivity.

In each of the embodiments described above, a neodymium magnet may also be used as the permanent magnet 125. [ However, since neodymium magnets are easy to drive due to a weak load at the initial stage of driving, there is a problem that a large load is required during high-speed rotation, and it is preferable to use the neodymium magnet when the power is transmitted to the rotary shaft 110 at low speed by natural force such as wind power. It is preferable to use it as a samarium cobalt magnet.

Hereinafter, specific configurations of the respective embodiments of the above-described embodiments will be described with reference to the accompanying drawings.
