Publication number: 20130319012Abstract: A magnetic cooling device is provided, including a magnetocaloric module and a magnetic unit movably disposed around the magnetocaloric module. The magnetocaloric module comprises a bed, a first magnetocaloric member, a second magnetocaloric member, and a third magnetocaloric member received in the bed, wherein the first and third magnetocaloric members are respectively close to a cold end and a hot end of the magnetocaloric module. Specifically, the first, second, and third magnetocaloric members are arranged along a central axis of the magnetocaloric module, and the weight of the third magnetocaloric member exceeds that of the first and second magnetocaloric members. A thermal fluid sequentially flows through the first, second, and third magnetocaloric members to transfer heat from the cold end to the hot end of the magnetocaloric module.Type: ApplicationFiled: May 29, 2012Publication date: December 5, 2013Inventors: Chung-Jung KUO, Tze-Chern MAO, Chieh-Shih CHANG, Tiao-Yuan WU, Sheng-Fan HSIEH, Min-Chia WANG
