Fast Cool Down Thermoelectric Cooler.
Abstract
This report covers the design and fabrication of a fast cool thermoelectric module for cooling infrared detectors to 195-K in 10 seconds or less. This cooler represents the latest state-of-the-art thermoelectric capability in fast cool down modules. This report discusses device design techniques and test results for the fabricated units. Where standby electrical power is available, cool down time required to cool a substrate surface to 195 K in a 300 K ambient may be as low as 1.3 seconds. Where standby power was not available, the cool down time required to cool a substrate surface from 300 K to 195 K was 11.5 seconds. Two detector cooler assemblies including the vacuum housing were delivered to NVL, Fort Belvoir for evaluation. A 15 second power booster was also delivered. (Author)
