Lightweight, High Efficiency Cryogenic Heat Exchanger Navy SBIR FY2012.2 Sol No.: Navy SBIR FY2012.2 Topic No.: N122-128 Topic Title: Lightweight, High Efficiency Cryogenic Heat Exchanger Proposal No.: N122-128-0310 Firm: NanoTechLabs Inc. 409 W. Maple St. Yadkinville, North Carolina 27055 Contact: Matthew Craps Phone: (336) 849-7474 Web Site: www.nanotechlabs.com Abstract: Through this effort, NanoTechLabs Inc. will improve the efficiency and lower the mass of the cryogenic heat exchanger used in American Superconductor's High Temperature Superconducting Degaussing system. NanoTechLabs will achieve these goals by producing a Carbon Nanotube metal matrix composite. Carbon Nanotubes have a room temperature thermal conductivity of ~3000 W/m K and a density of ~1.3 grams per cubic centimeter. NanoTechLabs will work with American Superconductor to achieve the highest improvements in efficiency and mass reduction. American Superconductor will ensure that our test pieces produced will get the most relevant testing available. Benefits: NanoTechLabs anticipates this technology will allow for faster cooling of the cold finger, and lower operating temperatures. These lower temperatures will enable higher efficiency in the superconducting system. In addition to these benefits, there will be a weight savings and stronger impact resistance. By utilizing powder metallurgy techniques we will be able to easily reproduce many different cold components in cryogenic systems that will benefit from higher thermal conductivity. Return
