PALO ALTO, Calif., Aug. 25, 2015 /PRNewswire/ -- Lockheed
Martin (NYSE: LMT) scientists are packing three times the power
density into a key satellite cooling system whose previous design
is already the lightest in its class. This project continues the
company's effort to reduce component size, enabling compact,
higher-power spacecraft payloads and smaller sensor platforms back
on Earth.
Highly sophisticated electronics like satellite sensors and
cameras need to be cooled to detect what they're designed to
capture, even to temperatures as low as -320 F (-195 C). Smaller
cryocoolers mean more affordable satellites and launches, and they
have applications on Earth, too. With higher power, this
microcryocooler enables larger, more sensitive IR sensors, which is
especially useful for very high-resolution images. Despite its
increased capability, the component's power efficiency rating is
roughly the same as lower-power coolers.
"The High Power Microcryocooler is making a large impact for
small products," said Dr. Jeffrey
Olson, a research scientist at Lockheed Martin's Advanced
Technology Center. "Our previous design was a revolution in size,
and now we're taking it further and packing it with increased
power. This will make a difference for technology in space, on
naval ships and aboard aircraft."
The High Power Microcryocooler is a high-reliability system
designed for continuous operation over a lifespan in excess of 10
years.
The High Power Microcryocooler is the industry's highest power
density cryocooling system. It delivers more than 150 watts per
kilogram, a significant advancement from the 30-60 watts per
kilogram rating most space-rated cryocoolers deliver. It also
weighs less than a pound, which is less than half the weight of
similar cooling systems.
