Cooling technology for JTRS Ground Mobile Radio (GMR) Communications Systems

The primary objective of the proposed Phase II study is to implement a new high-performance cooling technology for thermal management of the Joint Tactical Radio System (JTRS) Ground Mobile Radio (GMR). Having successfully demonstrated the effectiveness of this cooling concept during the Phase I study, the proposed work will focus on determining all required cooling system hardware using an actual GMR frame, and verifying thermal performance using same frame. A complete cooling system will be designed and constructed that matches the power and geometrical constraints of the GMR. Tests will be performed in an environmental chamber capable of spanning the entire temperature range of the military tactical environment of the GMR to validate the performance of the cooling system. Findings from the study will be used to propose follow-up evaluation/commercialization plans.
