Thermal management of microprocessors by microfluidic phase-change cooling: ThermaSMART Project

Microprocessors are the basis of all electronical devices, but a constant cooling is necessary to durably maintain their speed. Microprocessor cooling can be achieved by using phase-change systems in which the condensation of a liquid leads to the production of cold. Ideally, the produced heat must be dissipated as fast as it was generated, but the current air-cooling systems are only 60% effective.

The complex fluid flows occurring in phase-change cooling systems are not yet fully understood and could be better optimized. This consortium gathers partners from 5 continents (Europe, Asia, Africa, North America and South America) in order to share knowledge about phase-change cooling within this multidisciplinary network, to develop theoretical models and experimental methods to better grasp phase-change cooling, and to design a new generation of cooling systems based on microchannels.

Elvesys will transfer its knowledge on microfluidics, microfabrication and entrepreneurship to the other members of the consortium in the frame of workshops and trainings. Our expertise in fluid handling, based on our fast and precise OB1 flow controller, as well as our experience in microfabrication, will be leveraged for designing the cooling microdevice.

Our sister company Cherry Biotech, also participating in this consortium, will share its experience in temperature control in microfluidic devices to develop an evaporator in microchannels, as a central brick for this new generation of phase-change cooling systems.


This project has received funding from the European Union’s Horizon 2020 MSCA-RISE under grant agreement No 778104 (ThermaSMART project).

Drop me a line

You have a research project in mind and you are looking for an industrial partner in microfluidics ?

I will study your proposition and come back to you quickly to find together the best way to collaborate on your project. If the submission deadline is coming soon, I will try to come back to you on the same day.

Since all of us initially came from public research lab, we are used to collaborate with research laboratories inside scientific consortium and new scientific projects are always welcomed.
