ACTIVE RADAR SYSTEM THERMAL MANAGEMENT

Beltran proposes an innovative thermal management system for high power solid-state lasers based on the Complex of Innovative Cooling Enhancement Technologies (CICET).CICET provides the highest reliability, flexibility of the thermal management with doubling of the sources of refrigeration, selectable for operational regimes:- Semi open cooling circuits.provide optional opportunities for full recirculating of the coolant or to blow out a fraction of the vapor of the coolant to cover peak demands of the refrigeration.- Ultra low frequency heat accumulation with Phase Changing Materials (PCM) for continuous operation of power radar system.- Planar microregenerators with PCM for the suppression of high frequency thermal pulsations.- Electrical intensification of coolant circulations, phase separation, boiling and condensation.- Ionization of the coolant for uniformity of its distribution.The expected combined increased cooling capacity will be in excess of 1000 Watt/cm2. Analysis of the experimental tests will be utilized for optimization and simulation of the intensified heat transfer for the Phase II design of the proof-of-principlehardware. Innovative cooling technique for high power radars will suppress overheating and excessive thermal cycling of space based high power electronic components. Application of the Cooling Enhancement technology will improve thermal management of powerfulspace- and ground-based computers, of microwave generators, space-based laser (SBL) and space-based radar (SBR). Experimental data and theoretical models and approximations will be utilized for the design and research of commercial, research and militaryproducts.
