Experimental study of downward heat pipe using principle of heat-driven pump.

Author(s) : HIRANO S., YAMAMOTO T., TAKAMURA Y., KATSUTA M.

Summary

A device which transports heat downward without any mechanical driving force is considered and its behavior is experimentally characterised in the case of a closed loop. The driving force for the device is generated by a heat-driven pump. The heat driven pump transforms thermal energy into kinetic energy directly using the phase change of the working fluid. Experiments are conducted under various conditions of input energy and initial pressure. The total pump head of this apparatus is estimated at 3.6 m when the initial pressure is standard atmospheric. This head is much greater than that of ordinary heat pipes.
