Abstract

We demonstrated considerable reduction of thermal contact resistance (TCR) in microscale using carbon nanotubes (CNTs), and applied this technology to a micro thermal switch for magnetic refrigeration. A micro thermal contactor with a PECVD-grown 10 μm long "CNT carpet" shows a TCR of ca. 600 mm2K/W at a contact pressure of 20 kPa. The reliability of this data was confirmed by the extrapolation of published data in macroscale based on an empirical equation. The Off/On thermal resistance ratio of the thermal switch was ca. 7.3.
