Cooling/Thermal Management System Development for Active Denial Technology (ADT) and High-Power Radio-Frequency vehicle Stopper (RF) Systems

The goal of this program is to develop compact, lightweight, low power thermal management systems for non-lethal weapons platforms, specifically the Radio Frequency Vehicle Stopper (RFVS) and the Active Denial Technology (ADT) system. In the Phase I effort, Mezzo designed thermal management systems for both applications which utilize Mezzo"s advanced micro tube heat exchangers and micro tube thermal energy storage (TES) devices. Micro tube thermal energy storage devices were shown to significantly reduce the power requirements of a radiator-cooled thermal management system bya factor of 10-20, but at the cost of weight. Micro tube TES devices reduced the power consumption (factor of 3 to 7) and weight (10% to 47%) of VCS-cooled systems. Mezzo considered several configurations for the TMS systems but determined that a split system with the low temperature components cooled by a vapor compression system and the high temperature components cooled by a radiator system was the most efficient. The thermal management systems designed in this program are simple, reliable, and robust and offer significant performance benefits over conventional heat exchanger technology. Mezzo looks forward to the opportunity to demonstrate the performance benefits of the micro tube heat exchanger technology on a full-scale thermal management system.
