Gravitational heat pipes for discontinuous applications.

Summary

The paper deals with the adaptation of gravitational heat pipes or thermosiphons (TS) to discontinuous or cyclic processes such as chemical heat pumps. Such TS must fulfil a two-mode working too: the TS working must be active/inactive according to the successive endothermal/exothermal phases of the cyclic process. Two kinds of TS blockage processes have been successfully experimented (on the liquid or on the vapour phase). A simple model demonstrates that realistic configurations of TS and reactor can easily reduce the drawbacks of the blockage process on the performances.
