Abstract

The miniature capillary pumped loop (CPL) has great application potentials in thermal management of microsatellite and electronic devices because of its unique performance of high efficiency, isothermal and lightweight feature. This paper is aimed at development and experimental investigation on operational characteristics of a miniature CPL. The experimental studies include different cases such as thermal behaviors of the miniature CPL corresponding to the start-up, abrupt variation of the heat load, frequent shut-down and start-up re-start, and frequent adjustment of the set-point temperature of the reservoir under the anti-gravity condition. The temperature oscillation phenomena are also studied. Through the experimental data, the main factors of affecting thermal feature of the miniature CPL are discussed and the possible approaches of improving the operating performance of the miniature CPL are suggested.
