Abstract:
A magnetic refrigerator comprises a working material (23) radiating heat when a magnetic field is applied thereto and absorbing heat when the magnetic field is removed therefrom, and magnetic coil (23) which is movable for selectively applying or removing the magnetic field to or from the working material. Directional heat pipes are disposed between the working material and an object (28) of cooling, whereby heat from the object of cooling is transmitted to the working material when the working material absorbs the heat, and whereby heat from the working material is prevented from being transmitted to the object of cooling when the working material radiates the heat.
