Abstract

The aim of this paper is to detail the heat transfer characteristics and transport power of the Self-Exciting Mode Oscillating Flow (SEMOS) Heat Pipe. The enhanced heat transfer performance of a non-uniform cross-section closed loop SEMOS HP is tested and compared with the uniform profile SEMOS HP under same heating conditions. As a result, the heat transfer rate of the SEMOS Heat Pipe with a non-uniform profile could be increased under certain conditions, which forms the basis for future research and development of new SEMOS Heat Pipes. Keywords: laser heating, non-uniform profile SEMOS Heat Pipe, heat transfer enhancement, experimental investigation. 1 Introduction A new era in heat pipes began with the Pulsating Heat Pipe, invented by H. Akachi in 1994, and later called the Self-Exciting Mode Oscillating-Flow Heat Pipe [1, 2] (SEMOS Heat Pipe). Although it has only been known about for ten years, the SEMOS Heat Pipe is attracting worldwide attention because of its
