Danish Technological Institute and Heatflow have accomplished improvement of a 3D-printed cooling part for knowledge facilities by the AM2PC analysis undertaking. The system achieved a cooling capability of 600 watts throughout testing, exceeding the unique goal of 400 watts by 50 p.c. The answer makes use of passive two-phase cooling expertise that operates with out pumps or followers.
The cooling system addresses rising vitality calls for in knowledge facilities, the place GPU energy consumption has elevated from 100-200 watts to a number of hundred and even kilowatts in recent times. “Moreover the precise IT {hardware}, the corresponding cooling infrastructure is likely one of the main vitality customers in a knowledge middle – and due to this fact the best potential to enhance general system effectivity,” explains Simon Brudler, 3D-printing specialist and senior guide at Danish Technological Institute.
The expertise operates on a thermosiphon precept, the place coolant evaporates at sizzling surfaces and naturally rises on account of density variations. The vapor then condenses elsewhere and returns as liquid by gravity, requiring no vitality enter for the cooling course of. “With our two-phase resolution, we are able to take away warmth passively with out pumps or followers, which considerably reduces the vitality consumption for cooling,” says Paw Mortensen, CEO of Heatflow.
The 3D-printed aluminum evaporator integrates all essential capabilities right into a single part, decreasing meeting factors and leak dangers. The system removes warmth at temperatures between 60 and 80 levels Celsius, making it appropriate for district heating networks or industrial processes. Life cycle analyses point out the answer might scale back complete emissions by 25-30 p.c per unit.
The AM2PC undertaking obtained funding by M-ERA.NET with assist from Innovation Fund Denmark, working on a complete funds of DKK 10 million from 2023 to 2025. Companions embody Open Engineering from Belgium and Fraunhofer IWU from Germany alongside the Danish organizations.
