Recent developments at Thales Cryogenics have been aimed at improving the performances of 100 W and 200 W input power class flexure bearing Stirling coolers.
The aim of these developments has been threefold: To enable multi-year operation with a vanishingly small failure probability (high availability), to increase the available heat lift at 77 K (high power for zero boil-off), and to extend...
FLIR Systems has recently developed and begun manufacturing a miniature linear Stirling cryocooler, the FL-100, which has been designed to meet the needs of compact systems using High Operating Temperature (HOT) detectors. These include low cost, long life, high efficiency, and a very compact packaging size. A compact and efficient drive electronics board, the Cryogenic Cooler Controller...
Cryocoolers can experience near-periodic heaving or side-to-side motion and acceleration in some applications, in particular on moving platforms. In this work, the effect of heaving and side-to-side movement on a Stirling pulse tube cryocooler was experimentally studied. Periodic heaving and swaying motions having various amplitudes and frequencies were imposed on a Stirling pulse tube...
For a good cryocooler, besides high efficiency at working temperature, the cool-down speed is also important for some applications. Because of the difference in structure and operation mechanism, different cryocoolers have different characteristics of cool-down speed. This work introduces a Stirling type pulse tube cryocooler with ambient displacer which works at liquid nitrogen temperature...
High capacity Stirling type pulse tube cryocoolers (SPTCs) have promising prospect in high temperature superconductivity and gas liquefaction applications due to their definite potential of high reliability and high efficiency. However, impedance mismatching between the linear compressor and cold head in the high capacity SPTC becomes one of the main problems causing its inefficiency and...
