Patent ID: 7621046

Claim:
A molding process of a composite material including forming a high-thermal conductor and a room temperature magnetic refrigerant material, wherein said room temperature magnetic refrigerant material is nested with said high-thermal-conductor to obtain said composite material; and wherein said room temperature refrigerant material is processed to a shape of particle, sheet, or filament having a diameter or thickness greater than 0.001 mm, and the composite material is in a shape of particle, sheet unit, or filament having a diameter or thickness smaller than 1 mm, wherein the melting point of said high-thermal conductor is lower than that of said room temperature magnetic refrigerant material; melting said high-thermal-conductor under a vacuum or an inert atmosphere; adding said room temperature magnetic refrigerant material to said melted high-thermal conductor; cooling said melted high-thermal conductor containing said room temperature magnetic refrigerant material under a vacuum or inert atmosphere and forming a solid; and machining said solid to small balls having diameters of less than 0.5 mm.
