A fluid-handling system including a stator (14) and a rotor (10) which are rotatable with respect to each other around a common axis (13) and radially separated by an annular gap (17), where one of said components contains at least one element comprising magnetocaloric material (15, 16) and the other component comprises means to impose a magnetic field on said magnetocaloric material and is adapted to alternately magnetize and demagnetize said material, and means to bring said material into thermal contact with a fluid to change the temperature of that fluid, where the component containing means to impose a magnetic field comprises a plurality of pairs (11) of elongated permanent magnets (12), 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 magnet pairs face each other, in order to provide an intensified magnetic field that extends radially across said annular gap (17). |
