In addition, in The technology of U.S. Patent No. 4,107,935 also discloses a refrigerator using a rotating magnetic material, which mainly circulates a working fluid through a pump through a specially designed rotating 1243884 magnetic heating device. This rotating magnetic step is loaded with magnetocaloric material and continuously rotates unidirectionally in a strong magnetic field and a weak magnetic field, and the working fluid is sent into the rotating magnetic device. …, The complex flow path of the inner sigh leaf in the farm is exchanged with the magnetocaloric material to achieve the purpose of magnetic cooling. In the related magnetocaloric effect research, 'magnetic field intensity and magnetic field control are the fields that need to be researched, and & The use of hydro-magnets as the magnetic source has gradually replaced the design of super-conducted materials for super-conducted materials, which can simplify the needs of low-temperature operating environments. However, the current permanent magnets In terms of materials, its magnetic strength is much smaller than UTesla '. Therefore, for most applications of magnetic refrigerators, its magnetic heating effect is insufficient.

The permanent magnet u, 21 is provided in the rotor 10 and the stator 20 to increase the magnetic field strength when the magnetocaloric material 30 is magnetized. In the embodiment of the present invention, the geometry of the permanent magnet Η built into the rotor 10 The design is similar to the horseshoe type. Its geometric dimensions are designed to match the position of the salient poles of the stator. When any two adjacent magnetic supply coils 40 surrounding the salient poles of 1 to 8 are alternately supplied with current, When an electromagnetic field is generated, magnetic reluctance and electromagnetic torque effects similar to those of a rotating electric motor are generated to attract the permanent magnet η built in the rotor 10, thereby driving the rotor 10 to rotate repeatedly, and by being built in the rotor 10 and the stator 2 The magnetic circuit formed by the permanent magnets η, 2 丨 and the magnetic supply coil 40 surrounding the magnetocaloric material 30 can not only magnetize the magnetocaloric material 30, but also enhance the magnetocaloric material. 30 Magnetic field strength for performing the magnetization operation. In the preferred embodiment shown in the figure, there are a total of eight stator salient poles 〜 ~ 8, and the horseshoe-shaped permanent magnets embedded in the rotor 10 are two η and 11, and any one of the horseshoe-shaped Permanent magnets 丨 丨 or u each have two permanent magnetic poles ΠA, ΠB or 12A, 12B, so there are 4 permanent magnetic poles 12A, 12B, 12A ', 12B'. The shape design, 1243884 makes the two permanent magnet poles 12A, 12B of any permanent magnet 11 at the same time facing any two stator salient poles that are closest to each other but not adjacent (such as stator salient poles 1, 3) 'So At the same time, the four permanent magnetic poles 12A, 12B, 12A, and 12B of the two permanent magnets u and u, will be respectively connected with four stator salient poles (such as stator salient poles 1, 3, and 5). 7) The electromagnetic field generated by the magnetic supply coil 40 attracts each other. By causing the magnetic circuit to flow, the magnetocaloric material 30 provided on the surface of the stator salient pole is magnetized. According to this principle, the stator salient pole The total number is even, and the total number of permanent type magnetic poles of the permanent magnet u embedded in the rotor 10 is Half of the total number of stator salient poles. For example, when the permanent magnets embedded in the rotor 10 (three, and the total number of permanent magnetic poles is six, the total number of stator salient poles should be i 2, In order to strengthen the circulation of the magnetic circuit, the salient poles of the stator are directly opposite the horseshoe-shaped permanent magnets 11 or 11, and the permanent magnetic poles 12A, 12B, or 12 are at one end, and 128 are added. Fluxconce material body 60 (fluxconce, as shown in the figure, the size of the magnetic flux material material 60 can be larger than the size of one of the stator salient poles 1 to 8 and is equal to the permanent magnet 丨 丨 or u The permanent magnetic poles 12A, 12B or 12A ', 12B, have the same size to increase their magnetic induction capacity. Regarding the repeated rotation of the rotor 10 and how to use the magnetocaloric effect to achieve cooling in the process of repeated rotation The effect is described with the action of "Figure 2A ~ 2B"; in the case of "Figure", the four permanent magnetic poles 12A, 12B, 12a, and i2b of the horseshoe-shaped permanent magnets 11 and 11 ', * Don't directly face the salient poles of the stator 2,4,6,8 , 3,5,7 10 1243884 The current is supplied by the magnetic coil 40 (the current supply coil 40 is shown in the figure. The color of the magnetic coil 40 is shown in the color chart, and the magnetic coil 40 that is not supplied with current is white) And the generation—electromagnetic field 'thereby attracts the horseshoe-shaped permanent magnet 11 # σ „, and rotates in the direction of the arrow (clockwise) according to the figure. At this time, the magnetic heat set on the surface of the stator salient poles U, 5, 7 The material 30 will increase its temperature due to the operation of magnetization, which will produce an exothermic effect. ^ Μ Your brother's picture, "Nihon," and "J w" causes the magnetic coil 40 to supply an electric current to generate an electromagnetic field, thereby attracting a horseshoe. "The bodies η and η follow the directions shown by the arrows in the figure (the direction of the counterclockwise" movement 'at this time, the magnetocaloric material 30 disposed on the surface of the stator salient poles 2,4,6,8 will greatly increase: Operating to increase its temperature 'produces an exothermic effect; on the other hand, the magnetic supply coil 4G around the stator salient poles 1'3'5,7 of g stops supplying current to live. The magnetocaloric material 3 () placed on the surface of the salient salient poles 1, 3, 5, and 7 also reduces the temperature due to the demagnetization, resulting in the effect of heat absorption. In this way, through the magnetization and demagnetization operation of the magnetocaloric material 3 {) disposed on the surface of any two adjacent stator salient poles (ι, 3, 5, 7, or 2, 4'6, 8), it can promote The magnetocaloric material 30 generates a magneto-caloric effect of exothermic and endothermic heat, that is, through the first heat pipe 51 and the second heat pipe 52 having thermal contact with the magnetocaloric material 30, the magneto-caloric material 30 is caused to perform heat exchange with the outside world and achieve Cold effect. The role of the heat leaflet 7L · is to promote the magnetic heat material 30 to achieve heat exchange and cooling with the outside world. The first heat pipe 51 and the second heat pipe are a siphon type micro heat pipe structure. They both have Part of the length is attached to the surface of the magnetocaloric material 3 on both sides of the stator salient poles 1 ~ 8 (as shown in the "i" figure), while the other part extends to the repeatedly rotating magnetic field. The heat transfer effect of the cooling device 1243884 p 9 '1 heat pipe 51, 52 urges the magnetocaloric material 30 to perform heat exchange and cooling operation with the outside world.
