Thermal Management Components and Systems

TAI designs and fabricates custom cooling systems for cooling of critical system components for space, flight, and ground based applications. Below are examples of the systems that we have developed for past projects (though we no longer make these products):

Thermoelectric Cooler Interface

Thermoelectric Cooler Interface

Thermoelectric Cooler Interface

  • Assembled interface system and incorporated packaging of radar resonator.
  • Thermally isolating fiberglass supports (cylindrical vacuum housing not shown).
  • Uses two thermoelectric coolers (TEC) to cool to 250° K.
  • Demonstrated temperature stability of less than 0.001° K.

Initially developed for infrared-sensing satellite

  • All major components located in spacecraft bus
  • Compressor only active component
  • Flexible transfer lines route cooling fluid across busgimbaled optics
  • Requires no active control with variable load
  • Nearly constant temperature cooling
  • Accommodates thermal load leveling
  • Modular design for easy system integration
  • Potential cooling applications:
    • SBIRS-Low gimbal optics
    • ABL course pointing sensor
    • HTS resonator/waveform generator
    • Vibration sensitive systems

     

 

Cross-Gimbal Optical Bench Cooling Interface

Cross-Gimbal Optical Bench Cooling Interface

  • Flexible cooling loop demonstrated 110° K on-gimbal cooling for 15 W heat load.
  • Completed more than 73,000 full range gimbal cycles at operational temperature (equivalent 14-year on-orbit lifetime).
    • Azimuth axis: –180° to +180° and return.
    • Elevation axis: 0° to 90° and return.
  • Additional testing conducted to demonstrate cooling over an operational temperature range from 75 K to 125 K using:
    • Nitrogen
    • Methane
    • Argon.
