Abstract
The present disclosure relates to a magnetocaloric material property evaluation device that may substantially accurately analyze an adiabatic temperature change in a magnetocaloric material applied to a magnetic cooling system without relying on thermodynamic calculations.
Claims14
A magnetocaloric material property evaluation device, comprising:
- a base plate;
- a holder unit installed on an upper surface of the base plate, and including therein a specimen receiving depression formed to receive a specimen to be evaluated;
- a magnetic field applying unit installed rotatably in a double magnet structure on an outer circumferential surface of the holder unit, and configured to selectively apply/remove a magnetic field to/from the specimen depending on a rotating angle;
- a temperature control unit configured to control a temperature of the specimen by circulating fluid within the holder unit;
- and
- a temperature measurement unit configured to measure an adiabatic temperature change in the specimen to/from which the magnetic field is applied/removed by the magnetic field applying unit.
