Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: S1.09
Budget: 06/10/16 - 12/09/16

Closed-cycle cryocooler alternatives currently available for space applications in the temperature range of 10 to 20 K are not well suited to the requirements of such applications. In many cases reliability is low and vibration high. In other cases, coolers are too massive and inefficient. However, such coolers are often important components in ...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: H2.04
Budget: 06/17/15 - 12/17/15

A passive Pulsating Heat Pipe (PHP) system is proposed to distribute cooling over broad areas with low additional system mass. The PHP technology takes advantage of the large latent heat associated with phase change of a working fluid that is confined to small capillaries to carry heat efficiently from evaporator regions to a condenser that is ...

Phase 2 SBIR

Agency: National Aeronautics and Space Administration
Topic: 12-2-S1.06
Budget: 01/01/14 - 12/31/14

The innovation is a high-frequency single-stage pulse tube cryocooler (PTC) that operates at a heat rejection temperature of 150 K. It employs a flexure-bearing cold compressor operating at that same heat rejection temperature. High frequency, low temperature pulse-tube cryocoolers are a promising technology for future NASA missions. Such missio...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 12-1-S1.06
Budget: 01/01/13 - 12/31/13

The unique built-in design features of the proposed mini pulse tube cryocooler avoid all thermal expansion issues enabling it to operate within a cold, 150 K environment. As such, the cooler addresses the need to prevent boiloff of cryogenic propellants on long duration remote missions.Due to its high heat capacity regenerator matrix, the coole...
