Definitions

  • the present invention relates to a fluid-handling system comprising a device to change the temperature of fluid flowing through the system, said device relying on the magnetocaloric effect of magnetic materials to effect temperature changes. More particularly, the present invention concerns the means for imposing a magnetic field on said magnetocaloric material, i.e. magnetic material exhibiting a magnetocaloric effect.
  • fluid-handling systems such as ventilation/air- conditioning or chemical processing units
  • One of the functions of fluid-handling systems is to provide fluid at the right temperature for a particular environment.
  • regenerative heat exchangers in which incoming fluid is heated or cooled by thermal contact with material previously heated or cooled by outgoing fluid, are often used in such fluid-handling systems.
  • Refrigeration systems today are based on the gas compression cooling process.
  • the efficiency of these conventional refrigeration systems is only about 40% of the Carnot refrigeration cycle and the refrigerants used in these systems, such as chlorofluorocarbons, hydrofluorocarbons and ammonia, are harmful for the environment.
  • Magnetic refrigeration which has higher efficiency and is more environmentally friendly, compact and cost-effective, is being considered as an alternative technique to gas compression technology.
  • the magnetocaloric effect is the ability of certain materials to heat up in the presence of a magnetic field and cool down when the field is removed.
  • a magnetic material such as a ferromagnet or paramagnet
  • the magnetic moments of its atoms become aligned, making the material more ordered and thus decreasing the magnetic entropy of the material. If the magnetic field is applied adiabatically, the total entropy of the material must be conserved, so the material's atoms vibrate more rapidly, consequently raising the lattice entropy of the material and the material's temperature.
  • magnetocaloric material is magnetized by placing it in a magnetic field, which causes the material to warm up. Heat is removed from the magnetocaloric material while it is in the magnetic field, by bringing the magnetocaloric material into thermal contact with a heat-conducting fluid, for example. The magnetocaloric material cools upon its removal from the magnetic field. Heat can be absorbed from a thermal load by bringing the thermal load into thermal contact with the cooling magnetocaloric material immediately after it is taken out of the magnetic field. Continuous refrigeration of a thermal load can be achieved by repeating the described refrigeration cycle.
  • the temperature change arising due to the magnetocaloric effect depends on the magnetocaloric material used; it is proportional to the intensity of the applied magnetic field; and it's magnitude decreases with increasing difference between the material's temperature and it's Curie temperature.
  • the magnetocaloric effect reaches its maximum for a ferromagnetic material at the material's Curie temperature, the transition point above which thermally induced disorder overcomes the alignment of magnetic dipole moments of the material's atoms.
  • the magnetocaloric effect is relatively weak in most ferromagnetic materials at room temperature. Gadolinium is an exception as it's Curie temperature is 21 °C.
  • These new materials have been developed exhibiting an enhanced magnetocaloric effect, two to three times that of pure gadolinium.
  • These new materials include intermetallic alloys comprising lanthanides, such as gadolinium-germanium-silicon alloys, and Al-Ni alloys.
  • An 8 Tesla magnetic field such as that produced by a superconducting magnet, can produce a magnetocaloric temperature change of up to 15°C in some of these materials.
  • a common configuration of AMR devices is to incorporate magnetocaloric material into a wheel, ring, piston or the like and cyclically move the magnetocaloric material through a stationary magnetic field to alternately magnetize and demagnetize said material.
  • Rotary devices of this type give rise to the inevitable problem concerning fluid tightness since a heat- conducting fluid has to be brought into thermal contact with a moving body. Although this problem is not insurmountable, the components of the system transporting a heat-conducting fluid to, through and from the moving body have to be manufactured to within very close tolerances to avoid fluid leakage and thus a decrease in the thermal efficiency of the system. Furthermore, as friction is generated by the means of rotating the magnetocaloric material, the efficiency of such a system used as a refrigerator is lowered.
  • US 4532770 discloses a magnetic refrigerator utilizing a plurality of coils arranged on the outer peripheral surface of a hollow cylindrical rotor. Magnetocaloric material is arranged in a stator around the outer or inner periphery of said rotor and an air gap separates said rotor and stator. A current flows through said coils, to form a distributed magnetic field around the periphery of the rotor and when the rotor rotates a magnetic field is periodically applied to and removed from the magnetocaloric material in the stator, which is magnetized and demagnetized respectively.
  • superconducting coils are used to increase the intensity of the magnetic field to which said magnetocaloric material is subjected.
  • US 5182914 describes an AMR refrigerator comprising first and second elongated regenerative beds of magnetocaloric material positioned end to end and within fixed first and second inner dipole magnets respectively.
  • the two inner dipole magnets are connected in opposition so that the field produced by one is in the opposite direction to that of the other.
  • An outer dipole magnet that rotates around the longitudinal axis on which said regenerative beds are located, surrounds the magnetized regenerative beds.
  • the outer dipole magnet produces a magnetic field of the same magnitude as the inner dipole magnets transverse to its axis of rotation.
  • Said beds of magnetocaloric material are magnetized and demagnetized as the vector sums of the magnetic fields of the inner dipole magnets and the outer dipole magnet are added together upon rotation of the outer dipole magnet.
  • constructive interference increases the intensity of the magnetic field imposed on the first bed of magnetocaloric material positioned within the first inner dipole magnet.
  • anti-alignment of the magnetic fields of the outer dipole magnet and the second inner dipole magnet cancel each other out yielding zero intensity.
  • the field of the first inner dipole magnet is anti-aligned with the magnetic field of the outer dipole magnet which causes the magnetic fields to essentially cancel each other out while the intensity of the magnetic field experienced by the second inner dipole magnet is increased.
  • Said regenerative beds are brought into contact with a heat-conducting fluid.
  • a heat-conducting fluid In order to achieve a large temperature change of said fluid it is preferable to make the fluid to flow axially along the regenerator beds and to make them as long as possible so as to increase heat transferring time.
  • a system housing two beds of magnetocaloric material along a common longitudinal axis would be relatively large.
  • a large outer magnet as well as sufficiently powerful means to rotate said magnet would be required.
  • any imbalances in the system would give rise to an uneven rotation of the outer dipole magnet if attraction forces, arising when unlike magnetic poles separate, and repulsion forces, arising when like poles meet, were not overcome. Said imbalances would result in irrecoverable energy losses as the magnets were rotated.
  • a device that includes two components in the form of a stator and a rotor, which are rotatable with respect to each other around a common axis and radially separated by an annular gap.
  • One of said components contain at least one element comprising magnetocaloric material.
  • the other component comprises means to impose a magnetic field on said magnetocaloric material and is adapted to alternately magnetize said material contained in the other component in order to increase the material's temperature and demagnetize said material in order to decrease the material's temperature.
  • the device also comprises means to bring said at least one element comprising magnetocaloric material into direct thermal contact with a fluid to change the temperature of that fluid.
  • the component containing means to impose a magnetic field comprises a plurality of pairs of elongated permanent magnets, that are arranged substantially radially around said axis and magnetized so that unlike poles of each magnet pair face each other and like poles of adjacent permanent magnet pairs face each other. Since the resultant magnetic field at any point and time is the sum of all individual magnetic fields at that point and time, as the magnetic fields from adjacent magnet pairs are in phase and act in the same direction across said gap, the magnetic fields superimpose constituting constructive interference and thus providing an intensified magnetic field that extends substantially radially across said annular gap.
  • This arrangement of magnets is a very effective way to increase the magnetic flux density across the gap and in the magnetocaloric material, which consequently increases the magnetocaloric temperature change obtained and the heating/cooling capacity of the temperature-changing device.
  • the use of permanent magnets allows more reliable, simple and portable systems to be constructed. Furthermore, no electricity is consumed to produce a magnetic field leading to savings in operational costs.
  • the permanent magnets comprise neodymium-boron-iron, samarium-cobalt or ferrite and the term substantially radially is, here and as it stands in claim 1 , intended to also include elongated permanent magnets arranged parallel to each other in a pair.
  • the magnets are arranged either in the rotor or the stator of said temperature-changing device. Said rotor revolves either inside or around said stator. Arranging the magnets in the rotor and magnetocaloric material in the stator is however advantageous in that it simplifies the construction of a fluid tight system for the fluid that is brought into thermal contact with the magnetocaloric material.
  • the component comprising magnetocaloric material is encased in a magnetically soft material, such as iron, that contains the magnetic flux in a localized area.
  • said component comprising magnetocaloric material comprises laminated members, separated by insulating material for example, around said magnetocaloric material to hinder thermal conduction.
  • said stator comprises a substantially cylindrical member containing at least one element comprising magnetocaloric material around its inner or outer periphery, through which said fluid flows axially.
  • said stator comprises a substantially circular ring-like member containing at least one element comprising magnetocaloric material through which said fluid flows circumferentially i.e. via channels that are substantially parallel to the ring-like member's periphery.

  • said rotor is adapted to impose magnetic fields of different magnitudes on said plurality of elements comprising magnetocaloric material.
  • a fluid flows into direct thermal contact with each of said plurality of elements of magnetocaloric material. The temperature change of the fluid flowing past each element is determined by the choice of magnetocaloric material constituting the element and the intensity of the magnetic field to which said element is exposed.
  • Each element can therefore be used to provide a different amount of heating or cooling to fluids in a plurality of channels simultaneously using the same temperature changing device and thus achieve distributed heating or cooling, for example for different rooms in a building.
  • the fluid that is brought into thermal contact with said at least one element of magnetocaloric material is the fluid flowing through the fluid-handling system whose temperature is to be changed.

  • This grading of magnetocaloric material along an element is advantageous as the different magnetocaloric materials are arranged to correspond to the temperature profile that arises during the fluid-handling system's operation.
