Water pulsating heat pipe [PDF]

EPJ Web of Conferences, 2019
The new experimental setup with copper-glass pulsating heat pipe has been constructed for investigation of the heat transfer problem. Pulsations of liquid slugs inside the heat pipe has been observed. It is demonstrated that with increasing of temperature difference between evaporator and condenser heat flux which can be removed is also increases.

Pulsating heat pipe and embedded heat pipe heat spreaders for modular electronics cooling

Case Studies in Thermal Engineering, 2023
Two-phase-based heat spreaders are highly sought electronics cooling solutions due to their superior thermal performance over conventional conduction plates. Along with good thermal performance, Pulsating Heat Pipes (PHPs) potentially have thickness, shape matching and cost benefits over Embedded Heat Pipe (EHP) heat spreader solutions.

A Review Paper on Thermal Performance of Pulsating Heat Pipe [PDF]

E3S Web of Conferences, 2023
In past few years, as indirect convection cooling equipment, heat pipes have grown in favour for a variety of uses, including heat recovery and electronics. A sensible heat is categorized as not having a filter arrangement as a “pulsating heat pipe”.

Chaotic behavior of pulsating heat pipes [PDF]

International Journal of Heat and Mass Transfer, 2009
Chaotic behavior of closed loop pulsating heat pipes (PHPs) was studied. The PHPs were fabricated by capillary tubes with outer and inner diameters of 2.0 and 1.20 mm. FC-72 and deionized water were used as the working fluids. Experiments cover the following data ranges: number of turns of 4, 6, and 9, inclination angles from 5 degrees (near horizontal)
