INTRODUCTION
The CLOHP/CV is a very effective heat transfer device Akachi et al. (1): it has a simple structure and fast thermal- response. The CLOHP/CV consists of a long capillary tube bent into many turns and the evaporator section, adiabatic section and condenser section are located at these turns, with the ends joined to form a closed loop. It incorporates one or more direction-control one-way check valves in the loop so that the working fluid can circulate in specified direction only. Miyazaki et al. (2): studies the oscillating heat-pipe with check valves. It was found that the CHOHP/CV, as a high efficiency heat transfer. Pipatpaiboon et al. (3): studies ...
