Spacecraft Radiators

Part of either passive or active satellite thermal control systems, spacecraft radiators are designed to eject excess heat from spacecraft hardware to as part of controlling system temperatures as they experience the extreme temperature fluctuations in space. TMT designs radiators to fit any client’s needs, but specializes in the hardware that is placed on small spacecraft.

Deployable Radiator

TMT has developed a passive thermal control technology for rapidly assembled, modular spacecraft that provides a highly uniform radiator surface in conjunction with a high thermal conductance hinge. The currently developed hardware covers ranges of heat loads up to 100 watts but may be adapted for various sizes. TMT has qualified the passive thermal control hardware to TRL 6 through a series of space qualification structural and thermal-vacuum tests.

  • Thermally efficient radiator surface

  • Low thermal resistance hinge

  • Passive

  • Can integrate with a variety of release and actuation mechanisms

Have a Question?

TMT welcomes the opportunity to answer your questions or address any concerns you may have. We look forward to hearing from you today!

Radiator panels can also be designed and built as fixed radiators.
