    DESCRIPTION
    HEAT GENERATION DEVICE THROUGH MAGNETIC INDUCTION Technical sector
    The present invention is related to the generation of heat for heating applications, proposing a device that allows to produce heat by magnetic induction in cost-effective conditions for heating fluids or similar applications.
    State of the art
    It is known that when an electric conductive material element is disposed within the scope of a moving magnet, the influence of the variable magnetic field acting on said element generates heat that produces heating.
    Based on this phenomenon, solutions oriented to the heating of circulating fluids by a copper tube or other electrical conductive material have been developed, with a tube carrying a magnet carrier associated with a rotating drive motor being arranged in relation to the tube.
    Solutions of this type are described, for example, in documents ES1077579U, US2549362A, US20090223948A1, US5012060A, US7339144B2, US8408378B1o
    US20110272399A1, all based on approaches that use a magnet carrier support rotatably driven by a motor, to create a variable magnetic field by means of moving magnets in relation to a metal circulation tube of a fluid to be heated. These solutions have not, however, been successful in practical implementation, due to the low heat production performance they offer in relation to the energy consumption needed to rotate the carrier support of the magnets.
    Object of the invention
    In accordance with the present invention a heat generating device is proposed by

    magnetic induction, based on the movement of magnets, with which an efficiency is achieved that improves the performance of the solutions known in that sense and, consequently, the application performance.
    The device for generating heat by magnetic induction comprises an element of thermal conductive material with a channel for the circulation of a fluid to be heated, and a set of discs with permanent magnets that face the element of thermal conductive material and which are configured to exert a variable magnetic field on the element of thermal conductive material. The set of discs comprises first motorized discs and at least a second free spin disk, where the first discs are arranged around the second disc, such that the second disc is rotated by the magnetic influence exerted by the permanent magnets of The first albums.
    The heat generated on the element of thermal conductive material is a function of the number of magnetic field changes and therefore of the number of permanent magnets incorporated in the discs and the speed of rotation thereof. In this regard, the device and the invention proposes to use at least a second disk that rotates due to the magnetic influence exerted by the first discs that are arranged around the second disk, which allows reducing the energy consumption necessary to rotate the whole of the disks, thus increasing the functional performance of the device.
    The channel for the circulation of fluid is a groove that is directly made on one side of the element of thermal conductive material, so that the fluid is in direct contact with the element to be heated. Preferably, the channel has a rough surface to increase the area of contact with the fluid, and thus create a turbulent flow of the fluid that optimizes thermal transfer.
    On the face of the element of thermal conductive material that has the channel there is a closing lid with a sealing gasket that establishes a tight seal between the element and the closing lid, and therefore avoids possible losses that may occur in the channel through which the fluid to be heated circulates. The closure lid may be of a thermal conductive material, such as aluminum.
    The thermal conductive material element has a grooved distribution on the face

    opposite to where the channel is, so that the surface exposed to the variable magnetic field generated by the permanent magnets is increased, while said grooved area heats faster than the rest of the element material. Preferably, the slotted distribution has a reciprocal circular shape in the shape of the disk assembly that facilitates the rotation of the discs.
    Preferably, the disk set comprises four first disks arranged according to a quadrangular peripheral distribution and a second disk that is arranged in the center of the distribution formed by the first disks.
    The discs comprise a disk body with housings for permanent magnets, a pivot shaft and a first and second brackets that retain permanent magnets in the housings. The first support has a first internal threaded surface that threads onto a reciprocal external threaded surface of a first end of the axis of rotation, while the second support has a second internal threaded surface that threads onto a reciprocal external threaded surface of the disk body.
    The axis of rotation of the first discs has a second end with a grooved area for receiving a transmission means that connects the first discs in rotation, while the axis of rotation of one of the first discs is coupled to a drive motor, so that one of the first discs is driven directly by the motor while the rest of the first discs are driven through the transmission medium, the second disc being driven in rotation by the magnetic influence exerted by the first magnets of the first discs.
    Therefore, the heat generating device object of the invention results from constructive and functional characteristics that make it advantageous for the function for which it is intended, with its realization becoming a life of its own and preferential character with respect to conventional devices thereof. application.

    Detailed description of the invention
    The object of the invention relates to a magnetic induction heat generating device comprising an element (1) of thermal conductive material such as aluminum and a set of discs (2) with permanent magnets (3) that are arranged facing the element (1) of thermal conductive material, where the disks (2) with permanent magnets (3) are rotated, causing a variable magnetic field that expands on the element (1) of thermal conductive material by heating it. The element (1) of thermal conductive material has a channel (4) in the form of a coil through which a fluid to be heated circulates.

    The permanent magnets (3) of each disk (2) are arranged radially according to a distribution of alternating polarities, so that they exert a variable magnetic field that causes successive magnetizations and demagnetizations of the thermal conductive material of the element (1), which translates in an electromagnetic loss that produces heat that by thermal transmission heats the fluid in the channel (4).
    Said element (1) of thermal conductive material is a block preferably of a flat configuration that has one of its major faces the channel (4) for the circulation of fluid. The channel (4) is for example a groove that is directly made in the element (1) of thermal conductive material, so that the fluid to be heated flowing through the channel (4) is in direct contact with the thermal conductive material, maximizing thermal transfer. An inlet (5) and an outlet (6) of fluid to the channel (4) are arranged on one of the smaller faces of the element (1) of thermal conductive material.
    On the main face of the element (1) of thermal conductive material having the channel (4) there is a closing cover (7) with a seal (8) that establishes a tight seal between the element (1) of material thermal conductor and the closing cover (7) to avoid fluid losses from the channel (4). The closing cover (7) is made of a thermal conductive material, for example of the same material as the element (1), so that heat transfer to the channel fluid (4) is optimized.
    Advantageously, the channel (4) has a rough surface that allows to increase the area of contact with the fluid circulating through the channel (4), thus improving the transmission of heat to the fluid. The rough surface of the channel (4) can be bulges, fins, or any other form that causes a turbulent flow of the fluid circulating inside the channel (4), thus increasing the heating efficiency.
    As can be seen in Figure 5 and in the sectional views of Figures 6 and 7, the element (1) of thermal conductive material has a grooved distribution (9) on the larger face opposite the other major face where it is arranged the channel (4), said grooved distribution increases the surface and allows faster heating of the element (1). Preferably, and as seen in Figure 5, the slotted distribution (9) has a reciprocal circular shape to that of the disks (2), which favors the rotation of the disks (2) thus reducing the energy consumption for its actuation .

    The set of discs (2) with permanent magnets (3) comprises first motorized discs (2.1) and at least a second free spin disk (2.2). The first discs (2.1) are arranged around the second disc (2.2), so that the permanent magnets (3) of the first discs (2.1) generate a magnetic influence on the permanent magnets of the second disc (2.2) causing their rotation, with which it is possible to optimize the energy consumption of the device to drive the set of disks (2).
    Preferably, and as seen in Figure 3, the device comprises four motorized discs (2.1) and a free-rotating disc (2.2), thus the set of discs (2) is formed by four first discs (2.1) arranged according to a quadrangular peripheral distribution surrounding a second disk (2.2) that is arranged in the center of said quadrangular distribution close to the first discs (2.1).
    As can be seen in Figure 3, the number of permanent magnets (3) incorporated in each disk (2) is an even number, so that a distribution of alternate polarities in each disk (2) is obtained. Also, as seen in Figure 11, the permanent magnets (13) have a polarity on their upper face and a polarity opposite on their lower face, so that the generated magnetic field is directed in a direction perpendicular to the faces of the permanent magnets (3), and therefore the magnetic field is directed towards the element (1) to be heated since the disks (2) are arranged facing and parallel to the element (1) to be heated.
    As shown in Figures 8 to 11, the first discs (2.1) comprise a disc body (10) with housings (11) for permanent magnets (3) on its upper face, a rotation axis (12) that it extends in the axial direction of the disk (2.1) and supports (13, 14) of the permanent magnets (3) that close the housings (11) of the disk body (10).
    The axis of rotation (12) has a first end (12.1) that is available in a housing (15) of the element (1) of thermal conductive material (see figure 5) and a second end (12.2) that is available in a housing (16) of a support plate (17) of the device (see figure 1), so that the disks (2) are arranged with the possibility of rotation between the element (1) of thermal conductive material and the support plate (16).
    The axis of rotation (12) has at its second end (12.2) a grooved area (18) to receive
    5
    10

    twenty
    25
    30
    35
    a transmission means (19), such as a belt, distribution chain or the like, which rotates the first discs (2.1) in rotation. Thus, as seen in Figure 2, the axis of rotation (12) of one of the first discs (2.1) is directly coupled to a drive motor (20) disposed on the support plate (17), so that the rest of the first discs (2.1) are motorized through the transmission means (19) that transmits the rotation of the drive motor (20). It is also possible that each first disk (2.1) has an independent drive motor (20), but always the rotation of the second disk (2.2) is caused by the magnetic influence exerted by the permanent magnets (3) of the first discs (2.2) that are located nearby.
    The first support (13) has a first internal threaded surface that threads onto a reciprocal external threaded surface of the first end (12.1) of the rotation shaft (12), while the second support (14) has a second internal threaded surface that threads on a reciprocal external threaded surface of the disk body (11), so that the permanent magnets (3) are retained in the housings (11) of the disk body (10) by means of the supports (13, 14) making it impossible to movement, which is especially relevant to avoid deviations in the magnetic field lines and therefore misalignments in the axis of rotation (12) of the disks (2) that can adversely affect the performance of the device.
    The housings (11) have a reciprocal rectangular shape in the form of the permanent magnets (3) that are arranged in the housings (11). Said rectangular configuration of the permanent magnets (3) allows magnetizing a larger surface of the element (1), and therefore improving the heating efficiency.
    The configuration of the second disc (2.2) is identical to that of the first discs (2.1) except that it does not require having a grooved area (18) at the second end (12.2) of the rotation axis (12), since the rotation of the second disk (2.2) is carried out by the magnetic influence exerted by the permanent magnets (3) of the first discs (2.1).
    It is envisioned that the diameter of the second disk (2.2) is smaller than the diameter of the first discs (2.1), to facilitate its movement by magnetic influence, however the second disk diameter (2.2) could be equal to less than or greater than the diameter of the first discs (2.1).
