These include distributed cooling systems for zero boil off cryogenic storage tanks, in particular for actively cooled shields that may be used to eliminate the need for internal mixing with spray bars. The PHP could also be used to provide distributed cooling for radiation shields and large optical elements used in infrared space science missions.
There are also Missile Defense Agency applications, such as surveillance systems incorporating LWIR focal planes that require cooling of focal planes and optics to temperatures less than 40K. In addition, there are many commercial applications such as cooling superconducting power lines, superconducting magnets for power generation and energy storage and MRI magnets for medical applications.","description":"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 attached to the cold head of the cryocooler. This system will have an advantage over other distributed cooling approaches because it will be modular and can interface with any cooler that provides the required cooling power at the load temperature. The cooler may be a Stirling cooler, Pulse Tube cooler, reverse-Brayton cooler, Joule Thompson cooler, or some hybrid combination of these. Because the fluid flow is driven by fluid phase change caused by a temperature difference between the evaporators and the condenser, the loop is self-regulating. Flow is induced only when there is a thermal load. Also, because surface tension forces are dominant in the small capillaries of the PHP, this technology is suited for use in microgravity.","startYear":2015,"startMonth":6,"endYear":2015,"endMonth":12,"statusDescription":"Completed","principalInvestigators":[{"contactId":197258,"canUserEdit":false,"firstName":"James","lastName":"Maddocks","fullName":"James

The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
