“The World’s First Nucleate Boiling Vapour Chamber”

Who We Are

Privately owned spin-off from the National University of Singapore (NUS), founded in 2010.

Supported by SPRING Singapore, National Research Foundation (Singapore).

Developed a 2nd Generation enhanced vapor chamber heatsink to cool processors in the datacenter/server markets.

Awarded the 2010 SiTF New Emerging Technology Award.

“The World’s First Nucleate Boiling Vapour Chamber”

Technology (What is it, How it works)

Patent pending core that encourages nucleate boiling.

Unparalleled performance: up to 3 times more effective in heat spreading compared to plain surface vapor chambers.

Can be incorporated into various forms for different applications. Flat plate vapor chambers for IGBT cooling, CPU heatsinks etc

Application and Results (Server CPU cooling)

Gatekeeper built our enhanced vapor chamber into a 2U server heatsink to demo its performance against a typical heatpipe heatsink.

40% lower chip temperatures at 200W TDP heatload!

Applications

Cooling for Electric Vehicles/Motors

Solar

Other applications that require cooling for 50-100W/cm2

Gatekeeper Enhanced Two-Phase Heatsink

Decreasing Thermal Resistance with Increasing Heatloadcompared to OEM Heatpipe Heatsink
