1. A magnetic refrigerating device, comprising:
- at least one set of double-structured Halbach type magnet including a ring-shaped inner Halbach type magnet and a ring-shaped outer Halbach type magnet which are coaxially arranged one another so that a magnetic field generated from said inner Halbach type magnet is superimposed with a magnetic field generated from said outer Halbach type magnet;
a magnetic refrigerant or a magnetic refrigeration working chamber including said magnetic refrigerant therein disposed in a bore space of said inner Halbach type magnet; and
a rotating mechanism to rotate said outer Halbach type magnet while said inner Halbach type magnet is stationed.

Abstract
A magnetic refrigerating device includes: at least one set of double-structured Halbach type magnet including a ring-shaped inner Halbach type magnet and a ring-shaped outer Halbach type magnet which are coaxially arranged one another so that a magnetic field generated by the inner Halbach type magnet is superimposed with a magnetic field generated by the outer Halbach type magnet; a magnetic refrigerant or a magnetic refrigeration working chamber including the magnetic refrigerant therein disposed in a bore space of the inner Halbach type magnet; and a rotating mechanism to rotate the outer Halbach type magnet while the inner Halbach type magnet is stationed.

11. A magnetic refrigerating method, comprising:
-
disposing a magnetic refrigerant or a magnetic refrigerating working chamber including said magnetic refrigerant therein in a bore space of at least one set of double-structured Halbach type magnet including a ring-shaped inner Halbach type magnet and a ring-shaped outer Halbach type magnet which are coaxially arranged one another so that a magnetic field generated from said inner Halbach type magnet is superimposed with a magnetic field generated from said outer Halbach type magnet; and rotating said outer Halbach type magnet while said inner Halbach type magnet is stationed so that a first magnetic field with a first intensity is applied to said magnetic refrigerating material and a second magnetic field with a second intensity smaller than said first intensity is applied to said magnetic refrigerant, thereby generating a magneto-caloric effect in said magnetic refrigerant and thus, conduct a heat transfer. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
