Скачать или смотреть New satellite cooling system from Lockheed Martin

Lockheed Martin scientists are packing three times the power density into a key satellite cooling system whose previous design is already the lightest in its class. The project is in line with 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 are designed to capture, even to temperatures as low as minus 320 Farenheit. Smaller cryo coolers 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.
