    HEAT GENERATION SYSTEM BY MAGNETIC INDUCTION
    5 Technical sector
    The present invention is related to the generation of heat for heating applications, proposing a system that allows to produce heat by magnetic induction in cost-effective conditions for heating fluids or applications
    10 similar.
    State of the art
    It is known that when in the field of the magnetic field a moving magnet is
    15 has an element of electrical conductive material, the influence of the variable magnetic field that acts on said element generates in it a heat that produces a heating.
    Based on this phenomenon, heating-oriented solutions have been developed
    20 of circulating fluids through a copper tube or other electrical conductive material, a magnet bearing disc associated with a rotating drive motor being arranged in relation to the tube.
    Solutions of this type are described, for example, in the Spanish Utility Model
    25 ES 1077579U and in US Patents 2549362, US 20090223948, US 5012060, US 7339144, US 8408378 and US 20110272399, all based on approaches using a magnet carrier support rotatably driven by a motor, to create by moving magnets a variable magnetic field in relation to a metal circulation tube of a fluid to be heated. These solutions have not, however, been successful in
    30 practical implementation, due to the low heat production performance they offer in relation to the energy consumption that is needed to rotate the carrier support of the magnets.
    Object of the invention
    In accordance with the present invention a heat generation system is proposed by -2


    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.
    This system object of the invention comprises two or more magnet bearing discs, arranged consecutively next to each other in the same plane, the discs being related to a motor drive that rotates the consecutive discs in opposite directions.
    On the carrier discs, the magnets incorporated therein are arranged circularly close to the periphery of the discs, so that when rotating the consecutive discs, there is a magnetic influence between the magnets thereof, whereby each of the Discs tend to spin counterclockwise consecutively adjacent.
    Thus, by applying the drive on the disks so as to rotate the disks consecutively adjacent in opposite directions, the force of the drive of rotation of the disks is added to the force of the drive by the magnetic influence between the magnets of the same, so that the force of the motor drive to rotate the disks at certain revolutions is reduced in the proportion that affects the action of the magnetic influence between the disks, thus resulting in the lowest necessary energy consumption.
    Under these conditions, if an electric conductive element is arranged in front of the consecutive magnet-bearing discs, such as a copper coil or the like through which a fluid circulates, said element is heated by the influence of the variable magnetic field of the magnets. of the rotating discs, under conditions that improve the heating performance obtained in relation to the energy consumption of the disk drive. For this, the motor drive of the magnet bearing discs can be operated by independent motors or by a common drive motor related to the discs by means of appropriate transmissions, without altering the object of the invention.
    The number of magnets incorporated in each rotating disk can be variable, keeping said number of magnets in relation to the speed of rotation of the discs to obtain a certain amount of heat by magnetic influence on a conductive element


    electrical position in front of the disks, so that with a greater number of magnets on the disks, the speed of rotation of the disks may be lower, which reduces the energy consumption of the drive, therefore it is important to establish a suitable combination distribution of magnets on the disks and the speed of their rotation drive, to optimize system performance.
    On the other hand, it is an important factor for the efficiency of heat production due to the magnetic influence on an electric conductive element located in front of the rotating magnets, the distance between the element to be heated and the magnets incorporated in the rotating disks , having proved experimentally that the greatest effectiveness is obtained with a distance between 2 millimeters and 4.5 millimeters, since with greater distance the yield is reduced to unprofitable values, while with distances smaller than those indicated the performance remains practically constant without improving, the adjustment of the assembly being more difficult.
    On the element to be heated, a block of electrically conductive material can also be arranged, in relation to which the optimum distance of the magnets incorporated in the rotating discs is established, with this arrangement being achieved that the heat generated by the magnetic influence of the magnets incorporated in the rotating discs accumulate in said block arranged on the element to be heated, from which the heat is transmitted more efficiently to the element to be heated, so that the functional performance is improved. Said block arranged on the element to be heated is provided to have a grooved surface in front of the rotating disks bearing the magnets, thereby also improving the heat generation that is produced by the magnetic influence.
    Therefore, the system of the invention results from characteristics that make it efficient and cost effective for the heating function to which it is intended, acquiring its own life and preferential character with respect to the known systems that have been developed for the same function.

    Figure 2 is a front view of two adjacent magnet bearing discs, located -4


    according to the arrangement of the system of the invention.
    Figure 3 is a schematic of an example of the system of the invention in relation to acoil on which a heat accumulator block that is generated by5 magnetic influence.
    Detailed description of the invention
    The object of the invention relates to a heat generation system by induction
    10 magnetic on an element (1) of electrical conductive material, for use in applications such as the heating of a circulating fluid by a copper coil or other electrical conductive material, which in such case is the element (1) to be heated, without this application being limiting.
    15 The recommended system consists of the arrangement of two or more disks (2) located consecutively next to each other in the same plane, each disk (2) having on it a distribution of magnets (3) and establishing in relation to said disks ( 2) a rotary actuation drive of the consecutively adjacent discs (2) in opposite directions of rotation.
    20 Thus, having that functional assembly in front of an element (1) of electrical conductive material, such as a copper coil or the like through which a fluid circulates, by rotating the disks (2) the movement of the magnets ( 3) causes a variable magnetic field to be created on the element (1) with each of the magnets (3), whereby
    25 generates a heat that heats said element (1).
    Under these conditions, the rotational operation of the disks (2) also makes each of them create by means of their magnets (3) a magnetic influence on each consecutively adjacent disc (2), tending to rotate it in the opposite direction, so that
    Between the consecutively adjacent discs (2), a rotating actuating force is added reciprocally, by magnetic influence between them, which is added to the driving force of the rotary drive, so that to obtain a given rotation speed a lower driving force and, consequently, lower energy consumption.


    It is a function of the number of magnetic field changes on said element (1), which in turn depends on the number of magnets (3) incorporated in the discs (2) and the speed of rotation of the latter, as less force is required. motor drive to obtain a speed of rotation of the disks (2), the energy consumption necessary to obtain a certain heating of the element (1) to be heated is also lower, which means an increase in functional performance.
    In that sense, through experimental tests it has been proven that, with disks (2) each provided with twelve magnets (3) in a circular distribution near the periphery of the disks (2), a cost-effective functional performance is obtained for practical applications of heating, with speed of rotation of the disks (2) between 2800 rpm and 5000 rpm, since with speeds of rotation below that range the functional performance is very small, while above that range the heat energy that is obtained in the element (1) to be heated is practically constant, so that increasing the speed above 5000 rpm the energy consumption of the drive is greater to obtain practically the same heat, so that the yield is reduced.
    The effectiveness of heat generation on the element (1) to be heated, is also dependent on the distance between said element (1) to be heated and the magnets that are incorporated in the disks (2), having been experimentally proven that the highest performance it is obtained with a distance between 2 mm and 4.5 mm, since if the distance is greater than that range the magnetic induction on the element (1) to be heated is very small and the performance is not acceptable, while if the distance It is less than that range, it does not practically improve heat production by magnetic induction on the element (1) to be heated.
    In the practical arrangement, the rotary drive of the disks (2) carrying the magnets (3), can be carried out individually by means of independent motors (4) actuators of the different disks (2), as the solution represented in Figures 1 and 3; but in the same way, without altering the object of the invention, the drive can be carried out in common by means of a motor (4) coupled to the different discs (2) by means of respective transmissions.
    The disks (2) carrying the magnets (3), can be two or more and be arranged in a successive linear distribution or according to any other distribution in which they are consecutively arranged in the same plane and so that all the disks (2 )


    consecutively adjacent turn in opposite directions. On the other hand, the number of magnets (3) incorporated in each disc (2) must be even, since the set of magnets
    (3) on each disk (2) they must alternately have opposite polarities.
    5 According to a practical embodiment, the element (1) to be heated is expected to gocovered by a block (5) of electrical conductive material, in the area facing the disks
    (2) magnet carriers (3), as seen in Figure 3, whereby the heat generated by the magnetic induction of the magnets (3) of the disks (2), accumulates in the block (5), from which it is transferred to the element (1) housed inside, thus being more efficient
    10 the use of heat generated by the system. In this case the distance of the magnets
    (3) incorporated in the disks (2) is established with respect to said heat accumulator block (5) that is disposed on the element (1) to be heated.
    The heat accumulation block (5) is also provided with a surface facing the
    15 discs (2) carrying the magnets (3), provided with a striatum (6), which also favors the use of magnetic influence for heat generation, while improving the functional performance of the system.
