Thermal Products Case Study

Bringing Deep Space Communication Technologies Closer to Earth

NASA SmallSat missions are growing rapidly in the next decade.  In order to expand communication capacity with ground stations, NASA is adapting its DVB-S2 communications standard from larger deep space satellites to increase science data return and enable greater numbers of SmallSats.

Just like your cell phone that starts to burn hot when you download a video from the Internet, these compact high bandwidth radios are overheating. . . and there isn’t much room in the SmallSats for complicated cooling systems.

Roccor’s “FlexCool” conformable micro heat pipe may be the answer. Within just a few months of discovering the problem, we qualified and integrated a FlexCool onto a DVB-S2 demonstration radio that was launched July 13, 2020 on TechEdSat-10. Problem solved. Nimble. Fast. Simple.

 

Refreshing the typical aerospace approach

  • We engineered the smallest and lightest thermal management solution to enable the DVB-S2 radio to maintain safe operating temperatures.
  • We minimized risk by developing a high-performance design that could be integrated into the electronics chassis late during spacecraft buildup.
  • Our solution, a thin conformable micro heat pipe moves heat from the radio to the satellite walls creating a better passive heat rejection pathway: low risk, low price, higher performance, more effective.
