Advanced Cooling Technologies, Inc. was founded in January 2003 to develop innovative thermal technologies and commercialize these innovations. 


ACT has grown into a company with large engineering and manufacturing groups that specialize in custom advanced thermal solutions, focusing on two-phase transfer technology.


ACT has provided solutions for industries ranging from Photonics to Defense, Medical to Space.  


While passive heat pipe assemblies and embedded solutions have historically been the backbone of ACT, as power densities rise, Loop Thermosyphons and Pumped Two Phase systems are becoming more common.


  Our current technology portfolio includes:

  • Advanced vapor compression systems for space and airborne systems thermal control

  • Higher temperature (250 to 400°C) heat pipes and loop heat pipes

  • Pressure Controlled Heat Pipe Furnaces capable of ± 5 mK control over a wide temperature range

  • High heat flux cooling (> 1000 W/cm2)

  • Capillary and mechanically pumped two-phase systems for electronics cooling

  • Vortex enhanced direct contact heat exchangers for HVAC applications

  • Surface engineering for erosion/corrosion protection as well as enhanced two-phase condensing heat transfer

Heat Pipes

ACT is one of the leading manufacturers and suppliers of heat pipes in the United States. We produce a wide variety of heat pipes, heat sinks and heat pipe assemblies for thermal management of electronics and applications such as LEDs, card chassis, lasers, radar systems and medical systems. Our heat pipes offer a high thermal conductivity range of 10,000 to 100,000 W/m K and excellent shock/vibration and freeze/thaw tolerance. They also provide an extremely cost-effective thermal control system

HiK Frames quickly spread heat or mo

The patented Isothermal Card Edge (ICE)-Lok™ is designed to enhance thermal performance for conduction cooled embedded computing systems.


HiK Frames quickly spread heat or move heat to an edge for dissipation


Copper-water heat pipes provide a cost effective, highly reliable heat transfer device to manage mission critical electronics


HiK Heat Sinks extend the limits of air-cooled applications for both forced and natural convection
