SBIR-STTR Award

Pumped refrigerant cooling systems offer significant improvements in size and power consumption when compared to single phase cooling systems for electronics cooling application. This work will improve pumps for low net inlet pressure available applictions, extend the application of microchannel condensers to non-traditional geometries and improve the ability to integrate pumped refrigerant to vapor compression cycles.

Benefit:
If successful these developments will increase the scope of applications for pumped refrigerant systems.

Pumped refrigerant cooling systems offer significant improvements in size, weight and power consumption when compared to single phase cooling systems for electronics cooling applications. This work will develop improved pumps for low net inlet pressure available applications and apply these improved pumps along with the balance of the pumped refrigerant hardware infrastructure to Active Denial Technology (ADT) and High-Power Radio-Frequency vehicle Stopper (RF) Systems.

Benefit:
If successful, these developments, especially refrigerant pumps will be used in commercial electronics cooling systems.
