Frequency Analysis on Pulsating Heat Pipe

ASME 2007 InterPACK Conference, Volume 1, 2007
The pulsating heat pipe should have one eigen frequency based on the temperature visualization of pulsating heat pipe. The preliminary model of pulsating heat pipe is established by the force balance between the driving force, the inertial force and the frictional force.

State of the Art on Pulsating Heat Pipes

ASME 2nd International Conference on Microchannels and Minichannels, 2004
In recent years, thermal management of microelectronics is becoming a major feasibility bottleneck and has shown the limitations and shortcomings of conventional solutions. Market expetations are posing a simultaneous challenge of increased power levels coupled with high heat fluxes.

Closed-loop pulsating heat pipe

Applied Thermal Engineering, 2001
Flow visualization was conducted for the closed-loop pulsating heat pipe (PHP) using a charge coupled device (CCD). It was observed that during the start-up period, the working fluid oscillates with large amplitude, however, at steady operating state, the working fluid circulates.

Experimental research on heat transfer of pulsating heat pipe

Journal of Thermal Science, 2008
Experimental research was conducted to understand heat transfer characteristic of pulsating heat pipe in this paper, and the PHP is made of high quality glass capillary tube. Under different fill ratio, heat transfer rate and many other influence factors, the flow patterns were observed in the start-up, transition and stable stage.

Research of heat emission in the pulsation heat pipe

2010
Розглянутий принцип роботи пульсаційної теплової труби. Розраховані середні коефіцієнти тепловіддачі в зонах нагріву та конденсації в залежності від параметрів охолодження та теплового потоку, що передається. Виявлена нерівномірність тепловіддачі в різних петлях ПТТ.
