Important results from the project
The goal of MUCOOL has been to build a fully functional cooling plate that includes RF and digital feedthroughs as well as channels for fluid cooling. The project has manufactured such a cooling plate with a cooling capacity of >10 W per square centimeter and also validated its function in a testbed with automated control. The next step is to integrate electronics into the heatsink and validate its function at the system level.
Expected long term effects
The technology developed within the project is vital in radar and telecom systems. The understanding that has been built around modeling 3D printed materials and material systems where these materials are included will enable increased performance in telecom and radar components. The increased performance will in turn translate to significantly improved quality of service in future telecom systems as well as significantly improved reliability and precision in radar-based security systems.
Approach and implementation
The project has been carried out with four parties, two end users, a technology supplier and a university. Chalmers acted coordinator with operational project management from Saab, which in collaboration with the other end user (Ericsson) has designed the cooling plate. RISE has been responsible for manufacturing and has been involved in both the design work carried out by the end users Saab and Ericsson, as well as modeling work and the construction of a test rig, which took place at Chalmers.
