Working Fluid Selection for Pulsating Heat Pipes

42nd AIAA Thermophysics Conference, 2011
The Pulsating Heat Pipe (PHP) is a novel, simply formed, wickless heat pipe that relies on the phase change induced motion of a contained working fluid to transport heat between the evaporator (hot end) and condenser (cold end). The improved heat transfer capability (effective conductivities of more than 18,000 W/m-K at 105 W/cm), simplicity, and ...

Heat Transfer Characteristics of Aluminum Plate Pulsating Heat Pipes

ASME 2011 Pacific Rim Technical Conference and Exhibition on Packaging and Integration of Electronic and Photonic Systems, MEMS and NEMS: Volume 2, 2011
Heat transfer characteristics of an aluminum plate pulsating heat pipe (PHPs) were investigated experimentally. Sizes, consisting of parallel and square channels as well as different cross-sections and different number of turns were considered. Acetone was used as working fluid.

Fabrication of polydimethylsiloxane (PDMS) pulsating heat pipe

Applied Thermal Engineering, 2009
Abstract This paper reports on the preliminary experimental results of using polydimethylsiloxane (PDMS) to manufacture a visual pulsating heat pipe with length, width and internal diameter of 56 mm, 50 mm and 2 mm, respectively, including the manufacturing process, the vacuuming management for filling and packaging.

Operating Characteristic Investigations in Pulsating Heat Pipe

Journal of Heat Transfer, 2006
Pulsating heat pipe (PHP) is an interesting heat transfer device. In this paper we focus on PHP heat transfer characteristics versus its operating temperature. In experiments of copper and stainless steel PHPs, results indicate that, at a same input power, both the total temperature differences (from the evaporator to condenser) and the evaporator ...

Bubble Nucleation in Pulsating Heat Pipes

In this work, experimental, and numerical investigations are presented that aim to allow further insights into the operational mechanisms of pulsating heat pipes. The focus is on the link between necessary wall superheat for bubble nucleation and thermal resistance.
