Abstract:
A solar thermochemical coupling phase change reactor(STPCR)integrated with heat pipe technology was presented.The core part of the reactor was a high temperatures special-shaped heat pipe(HTSSHP)which was composed of a flat heat pipe in disk-shape and multiple cylindrical heat pipes.The start-up characteristics of HTSSHP prototype was primarily tested at different initial temperatures and various inclination angles.Results showed that the influence of initial temperature on the start-up characteristics could be almost neglected.The HTSSHP could be started up successfully at the inclination angles of 0°,15°,30° and 45°.In addition,the inclination angle had different effects on flat heat pipe section and cylindrical heat pipe section of HTSSHP.The best inclination angle for the flat heat pipe section was 0°,and 15° for cylindrical heat pipe section.The feasibility of operating HTSSHP under solar conditions was proven and the advantages of its special structure was confirmed.
