“…Liu et al [57] developed a hybrid cooling system that combines the dewpoint evaporative coolers with heat pipes and the average annual COP of the ideal systems was around 34, leading to annual energy savings of nearly 90% compared to vapour compression cooling system. Wang et al [58] designed the integrated heat pipe system which integrates the heat pipe cycle with the vapour compression cycle and operates simultaneously. The results showed that the power usage efficiency of the data centre using this system can be 0.3 lower than that using the conventional air-cooling systems in cold areas.…”

“…Studies can be found, for instance, for solar applications (Zhang et al, 2014b), HVAC applications (Zhenying Wang et al, 2015) or electronic cooling applications (Kim & Kim, 2014). Most of the time, this kind of study focuses on the transient behaviour of the systems and the authors often compare their measurements with the results of transient numerical models.…”

Despite the numerous studies on heat pipes over the last fifty years, the development of predictive tools for the design of heat pipes remains challenging, even for conventional technologies. As a result, heat pipes are still the object of more than 250 scientific articles a year. The present review aims to identify and understand the current scientific approaches followed by scientists in heat pipe science. The different types of heat pipe are reviewed in order to identify the main phenomena involved in these systems. A brief overview of the heat pipe history is given and the different applications are presented. A global review of the recent studies on heat pipes is then presented. Advances are identified in terms of heat pipe characterisation, scientific issues linked to the working fluid, understanding of phase-change heat transfer in thin liquid films and system modelling. Examples of recent works are detailed to highlight the strategies that can be followed to answer the current issues. This global review enables to highlight the main advances on heat pipe science of the last five years and to draw perspectives on the forthcoming scientific results.

Experimental Investigations of a Passive Cooling System Based on the Gravity Loop Heat Pipe Principle for an Electrical Cabinet

This paper deals with the experimental research and verification of a passive cooling system operating on the principle of a loop gravity heat pipe designed for cooling electrical cabinets. This type of cooling works automatically by changing the state of the working substance and thus saves energy consumption. Since the designed cooling system ensures heat transfer from the interior cabinet to the outdoor space, where the heat can naturally dissipate to the surroundings, it is dustproof. The heat pipe consists of an innovative evaporator concept designed to minimize liquid and vapour phase interference in the refrigeration circuit. The aim of the research was to experimentally determine the limit performance parameters of the refrigeration system for different volumes of working medium in the evaporator and decrease heat loss in the cabinet interior. The designed device was verified experimentally and by mathematical calculations as well. The greatest benefit of the work is that the cooling device was able to ensure temperature conditions inside the electrical enclosure at a heat load of 2000 W under 60 °C, 1500 W under 55 °C, 1000 W under 50 °C, 750 W under 45 °C and 500 W under 40 °C.
