$GTCH ("GBT” or the “Company”), the design of its long range radio prototype design incorporates a thermal control system for efficient heat dissipation. Advanced thermal engineering efforts are invested to ensure reliable operation of the Infinia radio system. The design includes a forced air-cooling system that includes special intake, outtake and fanning components to maintain optimal operational temperature. The design includes a customized heat dissipating heat sink to be mounted within each component enclosure, with a specific orientation and shape. A unique cooling airflow path is designed to efficiently provide forced air venting keeping the circuitries at an optimal temperature. The design of the system contemplates taking into consideration the ambient air temperatures to enable efficient operations in hot regions around the world. A comprehensive design was developed to determine the thermal conditions for the radio transceivers within the mobile, base and repeater units. Experimental techniques and numerical simulations were used to study the various thermal paths to develop the optimal cooling airflow. The power and thermal management of the Infinia system are directly correlated to yield an optimal solution. A concurrent plant including topology, size and control optimization will be apply to both power and thermal domains to ensure reliability and high performance. An optimized thermal system is crucial especially if the system is targeted to be used for emergency and military applications worldwide.
