ACT Delivers Satellite Thermal Control Products

Lancaster, Pennsylvania – February 11, 2008 – Advanced Cooling Technologies, Inc. (ACT) has delivered heat pipe components and assemblies for thermal control of civilian and military satellites.

ACT’s Aerospace Products Group was responsible for designing and manufacturing these heat pipe components and assemblies. The launch dates for these satellites range from 2008 to 2012. ACT’s deliverables included Constant Conductance Heat Pipes (CCHP), a CCHP Payload Deck, and a Loop Heat Pipe (LHP) Radiator. The CCHP deliverables covered a total of twenty-one different designs, some of which required up to five, highly precision, three-dimensional bends. In one of the thermal control assemblies, a number of CCHPs collect heat from the payload deck and transfer it to a LHP evaporator. The LHP further transports the heat to a radiator for eventual dissipation. The radiator employs additional CCHPs for effective heat spreading and radiation. The following photos show examples of the CCHPs, payload deck and LHP radiator. ACT is continuing the production of additional ship sets of the heat pipes and assemblies

The Aerospace Products Group maintains an extensive Aerospace Heat Pipe Life Test Program to demonstrate the long term reliability of ACT’s heat pipe products. The life test program includes conventional aluminum/ammonia CCHPs as well as advanced high temperature heat pipes using water and intermediate temperature working fluids. Many of the life test heat pipes have accumulated more than 26,000 hours of operation at elevated temperatures.

The Aerospace Products Group designs and manufactures aerospace heat pipes and assemblies following ACT’s ISO9001:2000 and AS9100-B certified quality system. ACT obtained a 100% perfect score during the most recent surveillance audit by Intertek in December 2007.

ACT is a developer and manufacturer of advanced heat pipes, pumped liquid and two-phase loops, and thermal storage devices. ACT specializes in technology development and custom thermal product design and manufacturing. ACT’s technologies have been used in applications from spacecraft thermal control to catalytic reactor cooling to medical surgery temperature control. ACT currently serves customers worldwide in Aerospace, Military, Commercial, and Government R&D markets. Many of these customers are in the Fortune Global 500 list.
