Advanced Cooling Technologies, Inc. (ACT) has a large portfolio of products for spacecraft thermal control, including Constant Conductance Heat Pipes (CCHPs), Space Copper Water Heat Pipes (SCWHPs), Variable Conductance Heat Pipes (VCHPs), Loop Heat Pipes (LHPs), Accumulators for Pumped Fluid Systems, Phase Change Material (PCM) Heat Sinks, SpaceVPX solutions and Cold Plates for Thermal Vacuum Testing. In addition, ACT conducts Advanced R&D for Spacecraft Thermal Control in Satellites, Landers, Rovers, Habitats and scientific missions.
Aluminum-ammonia and aluminum-ethane CCHPs are used for spacecraft thermal control.
Aluminum-ammonia and aluminum-ethane VCHPs are used to maintain electronics within a narrow temperature band, over wide variations in power and sink conditions.
Space Copper Water Heat Pipes are suitable for direct contact with electronics, as well as improving the thermal conductance of spacecraft electronics chasses.
Aluminum-ammonia and aluminum-propylene LHPs are used instead of CCHPs when higher powers and adverse elevations are required.
PCM heat sinks store heat during high power pulses or for cyclic operation, reducing the size and mass of the radiator required.
High conductivity plates with embedded heat pipes. Engineered for spacecraft thermal management.
When operating in the vacuum of space, heat must be transferred long distances to adequate radiator surface area.
Accumulators are used to accommodate changes in the volume of a pumped loop across the broad temperature range experienced in spacecraft applications, from -40°C to +55°C. ACT also has designed and fabricated custom fluid/thermal test systems for ground testing.
