Abstract

Passive closed two-phase heat transfer elements as wicked heat pipes, wickless two-phase closed tubular and looped thermosyphons and wickless pulsating heat pipes represents a promising solution for dissipating and spreading heat from electronic equipment to an external coolant. The paper presents results and practical experience from the research of various designs of thermosyphons and pulsating heat pipes for thermal control of electronic equipment.
