Jet cooling technology

  Jet Cool, a start-up company born in the Lincoln Laboratory of MIT, has developed a cooling technology to provide data center servers and high-performance computing equipment with low energy consumption, high performance and reduced carbon emissions.

   The micro convection liquid cooling technology "SmartPlate" applied by JetCool in the server is similar to the integrated water cooler installed in some high-performance desktop computers, but the difference is that SmartPlate uses a small ejector to spray the coolant onto the hardware hot spot, eliminating the interface materials such as heat transfer paste that fill the gap between the chip and the radiator, which can minimize the thermal resistance. As a result, SmartPlate has achieved a significant improvement in heat transfer coefficient and is 10 times more efficient than traditional cooling systems.

    SmartPlate, which uses Jetcool micro convection jet cooling technology, makes the liquid cooling of the data center more efficient. This technology can transfer heat from the hardware more effectively, which is conducive to building a smaller cooling system. Deploying the JetCool cooling system to the server and HPC can cool chips with power consumption from 150W to 1000W, reducing the energy cost of the data center by 18% and water consumption by up to 90%.

     Jetcool compared and tested the performance of SmartPlate cold plates for copper microchannel cold plates from leading manufacturers. The results show that its thermal resistance has been reduced by three times. The significant improvement of thermal resistance is an important step towards promoting higher TDP processors. In addition, due to efficient fluid dynamics and hot spot positioning, SmartPlate achieves a high performance level with less pumping power than its competitors, providing a more sustainable solution for server liquid cooling.
