Advanced Liquid Cooling System Navy SBIR FY2010.2 Sol No.: Navy SBIR FY2010.2 Topic No.: N102-114 Topic Title: Advanced Liquid Cooling System Proposal No.: N102-114-0546 Firm: Physical Optics Corporation Information Technologies Division 20600 Gramercy Place, Bldg. 100 Torrance, California 90501-1821 Contact: Vladimir Esterkin Phone: (310) 320-3088 Web Site: www.poc.com Abstract: To address the U.S. Navy's need for innovative thermoelectric cooling augmentation for the E 2D liquid cooling system, Physical Optics Corporation (POC) proposes to develop a solid-state Advanced Liquid Cooling System augmentation module based on TEC and an extended surface liquid heat sink. The design innovations provide an additional PAO temperature drop (delta T = 5�F) upstream of the existing E-2D LCS inlet. This drop results from innovations that significantly reduce parasitic energy losses in a semiconductor structure (up to 75%), optimization of the cooling medium rate in the TEC (25% of total PAO flow), improvements in the thermal performance of the heat sink (62.5% compared with conventional technologies) and a low system turn-on time. The ALCS's rugged modular design and reliance on mature fabrication technologies offers high reliability with a minimum MTBF of 6,800 hours. In Phase I, POC plans to design this module via CFD modeling and experimental research. A TRL-3 proof-of-concept prototype capable of removing 1,000 Btu/hr of thermal load will be assembled and tested to demonstrate feasibility of the ALCS. Refinement of this design will lead to a TRL 6 13,000 Btu/hr prototype in Phase II capable of accurately regulating the temperatures in the cooling loop Benefits: Military applications of the ALCS technology will include cooling for engines, laser sources, and virtually any air vehicles with available electric power that use a liquid cooling system and require additional cooling capabilities. Because ALCS helps solve the constant problem of removing heat from any power-consuming system, it has tremendous opportunities for application in the commercial sectors. For example, the ALCS can effectively cool electronics and improve heat removal in refrigeration cycles. Most systems with heat-exchanging technology will benefit greatly from the ALCS design. Return
