“…With its high performance, variety, and ease of construction, the pulsating heat pipe (PHP) has emerged as one of the most innovative, effective, and more convenient passive two-phase heat transfer systems since the early 1990s [15]. Visual investigation of ammonia PHP for start-up performance was conducted by [16].…”

Heat pipes are getting more popular as passively heat transmission technology, due to their excellent efficiency. It is popular in applications such as air conditioning, aviation, space technology, electronics etc. The performance, components, and applications of the most current heat pipe devices are completely analysed in this paper. The entire study objective was to improve people's understanding of heat pipes by gathering and organizing data that was easily and quickly available in a variety of forms across the material spectrum, displaying it in an ordered manner that went from basic to advanced knowledge about heat pipes, and contributing additional insight into the proficiency of considerations made during the design and fabrication of heat pipes as well as investigating how a change in heat pipe parameters affects performance. The study on heat pipes that has been done in terms of design and analysis is covered in this paper.

DEPLOY! Project aims at analysing the behaviour of Deployable Pulsating Heat Pipe (PHP) shaped as a helicoidal torsional spring in the adiabatic section on board a Parabolic Flight platform. A PHP is a passive thermal control device where the heat is efficiently transported by means of the self-sustained oscillatory fluid motion driven by the phase change phenomena. The microgravity environment allows to eliminate the buoyancy force contribution in the liquid phase momentum. Consequently, it is possible to isolate the contribution of the pressure drop caused by the 3D arrangement and infer on their effect on the PHP performance. As a result, a proper design based on the previous considerations would increase the flexibility of the PHP for use in space applications without significant reductions in efficiency. The goal of DEPLOY! is to demonstrate the functionality of a Deployable Pulsating Heat Pipe in various unfolding configurations by analysing its thermal-hydraulic response throughout a Parabolic Flight. The presented Deployable PHP is composed of an aluminium tube (inner/outer diameters 1.6mm/2.6 mm) and filled with HFE-7000. It is heated at the evaporator using a flat heater and cooled at the condenser with a water-cooled cold plate. T-type thermocouples are used to measure the wall temperature in several locations, while two pressure transducers (one located in the evaporator section and another in the condenser section of the same pipe) measure the local fluid pressure. Additionally, an IR Camera will be used to observe a section of the pipe for further analysis of the flow frequency. The device operation will be tested on ground and 0-g at different heat loads (24W, 34W), in multiple static positions corresponding to different opening angles (0°, 45°, 90°, 135°, 180°) and during its dynamic opening from 0° to 180°, thanks to a remotely controllable motion system.

“…Specifically, PHPs are achieving resounding interest within the scientific community due to their low manufacturing cost, good surface adaptability and high flexibility [5]. These fascinating features have been proven to be extremely useful in several thermal management applications, spanning from the automotive industry to the micro-electronics field [6,7], even though a large-scale employment of PHPs is nowadays undermined by a lack of knowledge concerning their working behaviour. This inevitably prevents the design of models able to reliably predict the PHP thermal performances.…”
