Military Cooling Applications

Military vehicles are designed to operate in extreme conditions including a large range in ambient temperatures, as well as shock, vibration, blowing sand, and driving rain, to name a few.  Many of today’s weapon and communication systems must meet these same requirements as they are vehicle mounted or transported to remote locations.  This generally results in many electronic components being mounted in sealed transit cases or enclosures to protect them from the austere environment.  This leads to the requirement for thermal management systems that can not only handle the heating and cooling needs for the electronics but must also be designed to survive the aforementioned environmental challenges.  Aspen has a long track record of successfully developing and manufacturing thermal management systems for a range of military applications.  These products have been tested and qualified to all the necessary Military Standards.  We have thousands of systems currently in use by the U.S. military and our allies.  Below are some examples of our applications.

Environmental Control Units for Electronics Kits on JLTV

  • The ECU-550 deployed successfully on MATVs
  • Electronics Kits on JLTV also require cooling
  • Aspen modified its ECU-550 to meet JLTV requirements

Ruggedized Air Conditioning for Military Electronics Enclosures

  • For many years it was the goal of electronics integrators to use Commercial-Off-the-Shelf (COTS) electronics in Military systems.
  • The Warfighter Information Network -Tactical program needed to implement a COTS solutions with active cooling.
  • Aspen Systems developed and qualified a ruggedized miniature air conditioning system to meet the requirements of operation on a moving vehicle and in Operational Transit cases.

Cooling of Airborne Sensors

  • The Kestrel system is deployed on aerostats over forward operating bases and uses a combination of cameras and technology to automatically detect insurgent activities.
  • The problem faced by the customer was that the nighttime capability needed an Infrared (IR) camera with active cooling.
  • Within three months of project initiation, production cooling systems were delivered by Aspen Systems for deployment at forward operating bases in Afghanistan.

Multi-Cold Plate Direct Refrigerant Cooling System

  • Many new systems such as lasers, and antennas require cooling to function in the austere military environment.
  • Direct refrigerant cooling provides an efficient, effective, and reliable option for cooling these systems.
  • Aspen Systems developed a direct refrigerant cooling system with 6 cold plates measuring over 10 square feet to cool a phased array antenna on a ground vehicle.

Cooling of Data Centers for the Department of Defense

  • The Department of Defense deploys data centers in the field for communications or cyber warfare and security.
  • The servers require active cooling to maintain safe operation in field applications.
  • Aspen Systems ECU-1800 provides 1,800 Watts of cooling power.
