Abstract:
1. A device ( 10 ) for generating cold and heat by a magnetic effect, the device comprising: at least one magnetic field generator ( 13 ; 130 ) being arranged in at least one crown segment and defining an annular space through which passes a coaxial circular element ( 11 ), the circular element being provided with transverse radial cavities ( 31 ) and containing at least one magneto-calorific material, the transverse radial cavities being arranged so as to convey a heat-carrying fluid in contact with the magneto-calorific material; means for introducing the heat-carrying fluid in an axial direction into the coaxial circular element ( 11 ); means for introducing the heat-carrying fluid along a radial direction into the transverse radial cavities ( 31 ); the means for introducing the heat-carrying fluid in the axial direction into the coaxial circular element ( 11 ) and the means for introducing the heat-carrying fluid along the radial direction into the transverse cavities ( 31 ) comprising at least one fluid circulating element ( 27 , 27 a , 27 b ) arranged to circulate the heat-carrying fluid; at least one first collector ( 33 ) arranged to receive the heat-carrying fluid after passing through the transverse radial cavities ( 31 ) into a zone containing the magnetic field generator ( 13 ); and at least one second collector ( 34 ) arranged to receive the heat-carrying fluid after passing through transverse radial cavities ( 31 ) into a zone located outside the magnetic field generator ( 13 ) and the magnetic field generator ( 13 ; 130 ) is fixed and the coaxial circular element ( 11 ) with the transverse radial cavities ( 31 ) is rotated about an axis by a drive motor (M) which is mounted coaxially with the coaxial circular element ( 11 ).
