TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Advanced Cooling Technologies, Inc. (ACT), supported by Hamilton Sundstrand, proposes to develop a heat pipe heat exchanger that is low mass and provides two levels of isolation between fluid streams. It has potential applications in thermal control of manned spacecraft and a number of military and commercial equipment and processes. Phase I has successfully demonstrated the feasibility of the heat exchanger technology in effectively exchanging heat between two fluid streams while providing reliable separation of the fluids. Components and subscale heat exchangers were tested and the results compared with the heat exchanger design model. The model demonstrated an accuracy of within 8% in its predictions. The principal Phase II objective is to fully demonstrate the proposed technology by refining and further developing the prototype heat exchanger into a qualified full scale design. The project will demonstrate the heat exchanger's long-term compatibility through life test of heat exchanger components and qualification test of engineering units at representative thermal, acceleration, shock and vibration conditions. The Phase II results will elevate the technology to a TRL 6: Prototype demonstration in a relevant environment. The follow-on Phase III will conduct flight qualification test of the technology to address micro gravity operation issues.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
NASA applications of the heat pipe heat exchanger technology include thermal control of manned spacecraft including the Shuttle, Space Station, and the planned CEV for Moon and Mars exploration missions.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Since manned spacecraft are not built in large quantities, Non NASA applications of the heat pipe heat exchanger technology include:

? Naval Turbine Bleed Air Coolers.
? Ammonia Refrigeration Plants.
? Food or Pharmaceutical Processing.
? Industrial Chemical Processing.
? Telecommunication outdoor cabinet cooling.
