Japanese firm NEC has developed a new cooling technology that eliminates heat produced by information and communications technology (ICT) equipment placed on the racks outside server rooms.
The technology applies phase change cooling technology, which eliminates heat when converting from liquid to vapour, therefore allowing efficient cooling.
Claimed to reduce the amount of air conditioning load in server rooms, the latest trials revealed that about 50% of the heat generated from the rack had been removed from the server room.
NEC said the new technology permits more ICT devices to mount on racks without boosting the air conditioning power and enhances processing capabilities without increasing their floor area.
The Japanese firm has also developed a multi-stage heat collection technology that removes the heat from each ICT device on the rack as required by converting liquid coolant to vapour.
Developed in line with the NEC Group Environmental Management Action Plan, the new cooling technology used research results from the New Energy and Industrial Technology Development Organization's (NEDO) "Research and Development Project for Green Network/System Technology".
