Data centres in Singapore consume about 7% of the electricity generated annually. A large proportion of the energy consumption (~50%) is for the cooling system necessary to keep the servers operating reliably under Singapore’s hot and humid ambient conditions. Current cooling systems rely on energy-demanding chillers and computer room air handlers to produce cold air which is passed through the IT equipment to mitigate the heat generated via sensible cooling.
The technology owner has developed a spray cooling system that aims to eliminate the need for chillers and reduce the energy requirements of the other associated equipment in the data centre cooling application. The spray cooling system uses dielectric coolant which is dispersed in small droplets through a spray nozzle that directly impinges on electronic components and absorbs heat from the operating heated server by evaporative or droplet impingement cooling mechanism. The vaporised coolant is then recovered by a condensing coil cooled by ambient temperature water (i.e. no cooling required by chillers) from a cooling tower, through which the heat is rejected to the environment.
The technology owner is seeking industry partners to co-develop and pilot the technology for data centre applications and in space or equipment that require high heat load cooling applications.
The patented spray cooling system design is applicable for following areas:
