High-frequency magnetocaloric modules with heat gates operating with the Peltier effect
چکیده انگلیسی


• A new alternative method for magnetic refrigeration.
• High-frequency device is more efficient and economical.
• Applicable to magnetic heating, refrigeration and energy conversion.

Magnetic heat pumps, refrigerators and energy conversion prototypes, with an operation based on the magnetocaloric effect, usually show a restriction in their frequency of operation to a few Hertz. In 2010 it was proposed to apply thermal switches to overcome this barrier. In this article thermal switches built with Ni-nanowire Peltier elements are presented and the performance of such elements is discussed on a theoretical and experimental basis. Finally an approximate estimate of the performance of a magnetic refrigerator of the types built up to present is compared to that of a magnetic refrigerator applying nanowire thermal switches.
