Pulsated two-phase thermosyphons for electronic equipment thermal control

This work proposes some heat transfer pulsating devices as interesting alternative solution to the LHP (Loop Heat Pipe) and CPL (Capillary Pumped Loop). These devices, named pulsated two-phase thermosyphon (PTPT) by the authors, have been studied, classified and experimentally observed in previous works. In this paper the operating principles of the PTPT devices in comparison with LHPs or CPLs for thermal control applications are illustrated. Although the LHP and CPL operate in a steady state regime of heat transfer and PTPT operates in a stabilized periodic regime, some important comparisons are presented. In conclusion the application of a PTPT could become a possible cheap choice in future in case of the thermal management of electronic devices. Copyright © 2002 Society of Automotive Engineers, Inc.
