Abstract:

Aqwest proposes to investigate an innovative staged magnetocaloric refrigerator (SMCR) for thermal management of spacecraft payload electronics. SMCR offers a high-performance approach for thermal management of laser communication equipment and infrared (IR) sensors, while improving the overall payload energy efficiency and reducing its weight. The proposed project will leverage previous work by Aqwest in thermal management of electro-optical equipment and offers the following major benefits for Missile Defense Agency (MDA) and the Department of Defense (DOD): Improved electrical efficiency Reduced jitter Reduced weight of payload and platform Simple, compact, and lightweight hardware Materials robust to radiation ensure lifetime > 10 years In Phase I, we will validate the SMCR concept via modeling and experiments using existing magneto-caloric effect (MCE) materials and permanent magnets to show the concept potential for cooling spacecraft payloads. In particular, we will develop 3D finite element models and predict SMCR performance, scaling of temperature differential, and refrigeration power. Moreover, we will develop and characterize each a magnet assembly and a heat flow switching, which are critical elements of the SMCR, and experimentally demonstrate their performance. Plans to further develop and exploit the technology in Phase II will be developed.
