Micro Cooling Device Now Gets Defense, Satellite Systems Up and Running 4x Faster



A new micro-size cryocooler from Lockheed Martin is enabling quick-startup infrared (IR) sensors for missile and sensor applications.

The Fast Cool Down micro-size cryocooler can cool an IR sensor in 3 minutes. It’s ultra-compact, too, with a cold head (right) that’s less than half the length of the previous model.

Cryocoolers are standard components in IR-sensing platforms, from space observation to weapons targeting, and this new highly-compact product enables faster activation and smaller packaging.

“The Fast Cool Down Micro Cryocooler makes sure our military can have rapid-reaction systems, from missile to passive sensor applications,” said Dr. Jeffrey Olson, a research scientist at Lockheed Martin’s Advanced Technology Center.

“We can cool an IR sensor in 3 minutes, versus the 12 to 15 minutes of current systems. That’s crucial when lives are on the line.”

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).

This micro cryocooler uses the same miniaturized compressor as the standard micro cryocooler but with a new cold head.

The innovative architecture allows engineers to reduce the cold head to just 54 mm long, less than half the length of the previous model.

And at just 320 grams the cooler still provides big capability even for compact, hand-carried weapon systems and small spacecraft, like cubesats. Plus, the Fast Cool Down Micro cryocooler delivers these capabilities with a decade-long design life.
