Thermal Solutions for Future Laser Weapon Systems

Advanced Cooling Technologies, Inc. announced today, Thursday, December 15, 2022, that the U.S. Air Force intends to fund ACT’s Phase I SBIR proposal, “Enabling Thermal Solutions for Future Laser Weapon Systems”.  Development will be supported by a commercial partner, who will provide industry knowledge on High Energy Laser (HEL) diode heat loads and general design guidance.

As the military continues to extend the power delivery of HEL systems, heat fluxes reaching hundreds of Watts per square centimeter are becoming commonplace.  Some researchers have reported heat fluxes even exceeding a kilowatt per square centimeter.  ACT’s proposed system was originally developed for high-frequency (> 100 GHz) Gallium Nitride (GaN) transistors and demonstrated successful heat flux management above 300 W/cm2.  In the Phase I program, ACT will extend this thermal management technology to HEL diode arrays and further push the limits of this approach.  The system combines the benefits of Pumped Two-Phase cooling, namely long transport distances and high heat transport capacity, with the high heat transfer performance of thin film evaporation.  Thin film evaporation is of particular importance as incredibly high heat transfer rates can be achieved.  However, this mechanism is often restricted by maintaining the film through sufficient liquid delivery.  ACT will address this through a unique porous media structure at the heated surface that will passively match the liquid delivery rate to the evaporation rate.

ACT Advances Energy Research with Over $1 Million from U.S. Department of Energy

Lancaster, Pennsylvania – Tuesday, July 5, 2022 Advanced Cooling Technologies, Inc. (ACT) announced today that it has been awarded six new Department of Energy (DOE) SBIR and STTR Phase I contracts, for a total of $1.2 million. The awards will advance research the following programs:

According to Jens Weyant, Vice President of R&D at ACT, “These awards demonstrate our commitment to expand into new and diverse energy-related research areas. The application of the Swiss-roll to ammonia reforming will allow us to further increase our competency in compact reformers and combustors.”

Ammonia (NH3) is a promising carbon-free energy source for future power generation. However, direct air-ammonia combustion has proven challenging to implement in gas turbine applications due to inherently slow reaction rates. ACT’s concept is to pre-crack part of the ammonia fuel into a hydrogen-rich reformate using a novel reformer and waste heat from the gas turbine. The partially cracked fuel will improve the reaction rates to levels that are on par with other carbon-based fuels.  More information on this and other related technologies can be found on our new web page, Combustion, Fuel Research, and Non-Thermal Plasma (

In 2011, ACT was awarded a Tibbets award from the Small Business Administration (SBA).  SBA presents the awards nationally to small companies and individuals that have advanced technical innovation and economic growth through its Small Business Innovation Research (SBIR) program.  “Many of ACT’s products were initially developed on SBIR and STTR programs.  Space Copper-Water Heat Pipes were originally developed on a NASA Marshall Phase II SBIR, while ICE-Lok™ an enhanced Wedge lock, was developed on an Air Force SBIR.” said Dr. William G. Anderson, Chief Engineer for R&D at ACT. “We continue to commercialize SBIR research, recently achieving product sales of $115 million from technology developed on SBIR and STTR programs.”
