Paper Abstract

An overview is presented of the status of a family of miniature linear coolers currently under development by Hughes Aircraft Co. for use in handheld, volume limited or power limited infrared applications. These coolers, representing the latest additions to the Hughes family of TOPTM (twin-opposed piston) linear coolers, have been fabricated and tested in three different configurations. Each configuration is designed to utilize a common compressor assembly resulting in reduced manufacturing costs. The baseline compressor has been integrated with two different expander configurations and has been operated with two different levels of input power. These various configuration combinations offer a wide range of performance and interface characteristics which may be tailored to applications requiring limited power and size without significantly compromising cooler capacity or cooldown characteristics.
