A Highly Stable Two-Phase Thermal Management System

The Air Force, Navy, and Army all project increasing heat generation in military vehicles from advanced electronics systems and weapons systems. Advanced thermal management technology is needed to control the temperatures in these systems. We propose to develop a highly stable two-phase thermal management system to meet these requirements. Our innovative system and component designs will effectively suppress flow instability in the system. The highly stable system will be very reliable and will absorb heat from multiple components efficiently. The system will remain stable even when the evaporator heat loads change rapidly. In Phase I, we successfully proved the feasibility of the critical components through laboratory testing, designed the Phase II laboratory-scale system, and showed by analysis that the flows in the system will be very stable at prototypical operating conditions. In Phase II, we will design, build, and demonstrate a highly stable two-phase thermal management system with multiple evaporators.
