Abstract:

Progress is reported on the development of a Peltier effect device for the cooling of an infrared detector to -78 degrees C through the use of semiconductor materials. A test set was developed which enabled the thermoelectric device to be tested at pressures down to .0001 mm Hg. A prototype two stage cooler was designed and tested. Its performance confirmed the basic calculations and has allowed the final three stage design to be completed. In design optimization studies the performance of cascaded devices was treated. A Dewar flask for the detector has been designed. Techniques for reducing junction resistance of thermoelectric devices were studied. The design of the cooler power supply was chosen.
