Two-phase micro-scale cooling implemented with passive, gravity-driven closed-loop thermosyphons represents a highly-reliable solution to increase heat dissipation and to maximize energy efficiency of the next-generation electronics cooling technologies. T ...

In the present paper, a closed-loop thermosyphon cooling system for power electronics has been developed and tested. The evaporator is a multi-microchannel heat sink designed for high heat fluxes. The power electronics module is emulated by four independen ...

Passive, gravity-driven thermosyphons represent a stepchange in technology towards the goal of greatly reducing PUE (Power Usage Effectiveness) of datacenters by replacing energy hungry fans of air-cooling approach with a highly-reliable solution able to d ...

This paper advances the work presented at ITHERM 2020 where a novel passive two-phase technology was introduced for more efficient cooling of datacenters compared to air-based cooling solutions (e.g. In-Room, In-Row, etc.). The proposed hybrid two-phase co ...

This study is focused on the experimental characterization of two-phase heat transfer performance and pressure drops within an ultracompact heat exchanger (UCHE) suitable for electronics cooling applications. In this specific work, the UCHE prototype is an ...

This paper advances the work presented at ITHERM 2019 in which a novel thermal technology has been introduced to cool servers and datacenter racks more efficiently compared to the traditional air-based cooling solutions. As reported in the state-of-the-art ...

As data centers grow exponentially in size and number worldwide, it appears evident that more efficient and reliable cooling solutions are needed to reduce energy consumption and noise level significantly. Thermosyphon-based systems have been proven to res ...

This paper advances the state-of-the-art in novel passive two-phase systems for more efficient cooling of datacenters and telecom central offices compared to the traditional air-based cooling solutions (e.g. aisle-based containment systems). The proposed p ...

The pulsating nature of a closed loop pulsating heat pipe (CLPHP) makes the prediction of its thermal-hydraulic performance extremely challenging. Unfortunately, the design of CLPHPs is still quite an empirical process, requiring testing of many prototypes ...

Due to the local pulsating/transient nature and complex thermal-hydraulic coupling of a closed loop pulsating heat pipe (CLPHP), there is a need to develop an effective simulation code capable to design and predict the local and overall thermal performance ...

With the advancement of technologies such as Artificial Intelligence and 5G telecommunications, where computational rate is constantly pushing its limits, highly efficient and reliable cooling devices are starting to become an overly critical factor. Not o ...
