Abstract

A small-scale thermal diode for operation near room temperature was designed from a heat pipe with an asymmetrical structure, and its operational characteristics were investigated. Directional control of heat flow was achieved with a heat flow ratio of about 42 and an overall heat transfer coefficient of 1.1×103 W/m2K even in the case of a temperature difference of less than 1 degree.
