Abstract

This paper details an experimental investigation of the cooling capability of a novel air amplifier in direct comparison to traditional rotary fans for data centre server cooling applications. A heated foil is placed in a polycarbonate flow channel designed to replicate the dimensions of an Intel S2600TP blade server. An IR camera monitors the thermal behaviour from underneath the foil for cooling experiments involving Coandǎ flow from the air amplifier and turbulent flow from the fans. Results show that the air amplifier produced higher average heat transfer coefficients particularly for higher flow rates (64 W/m2K) where the device's cooling performance doubled that achieved by the fans (29 W/m2K) for the same outlet flow rates. The air amplifier also outperformed the fans based on theoretical input power, again achieving higher average heat transfer coefficients. This study highlights the potential for the air amplifier in data centre cooling applications to reduce costs and eliminate waste.
