Drive and Control System for a Stirling Cryocooler
2002A drive and control system for a Stirling cryocooler has been developed. By accurately controlling the stroke, frequency, DC bias, and phase between compressor and displacer, the cooler can reach its lowest temperature of 43 K with no heat load. In order to minimize the induced vibration, two “Oxford type” single stage split Stirling cryocoolers are ...

Basic Limitations on the Performance of Stirling Cryocoolers
AIP Conference Proceedings, 2004The flow through the regenerator of a Stirling cryocooler is driven by differences in pressure at the warm and cold sides. These differences lead to power dissipation in the regenerator. The pressure distribution in the regenerator is found using linearized theory.

Miniature Stirling cryocoolers: trends in development
Cryogenics, 1986Abstract Following a lengthy period of development, Stirling refrigerators have emerged as the preferred system for the miniature cryocoolers used in infrared night-vision, missile guidance systems and other low capacity cryogenic sensors. Single stage expansion integral and split-Sterling refrigerators having capacities of 0.25-1 W at 80 K are in ...

Mathematical and Thermodynamical Analysis of Stirling Cryocooler
Research Journal of Engineering and Technology, 2017We envisage the bright future of Stirling crycoolers owing to its profitability in all respects. The piston free displacer (FPFD) an important type of miniature Stirling crycooler has been favored for the infrared sensors and electronic applications. Different devices like motor can control piston and displacer independently.

Magnetically Augmented Regeneration in Stirling Cryocooler
1994This paper describes how the magneto-caloric effect can be employed with direct entropy coupling between the magnetic entropy of the magnetic material and the pressure entropy of the gas in refrigeration cycle. A magnetic refrigerator generally works in the low temperature range below 4.2 K, rejecting heat to the higher temperature that is considered ...

Impedance match for Stirling type cryocoolers
Cryogenics, 2011Impedance match in Stirling type cryocoolers is important for the compressor efficiency and available acoustic power. This paper generalizes the basic principles concerning the efficiency and acoustic power output of the linear compressor. Starting from basic governing equations and mainly from the viewpoint of energy balance, the physical mechanisms ...

The Ball 12 K Stirling cryocooler
AIP Conference Proceedings, 2002At Ball we have been making progress towards the creation of a 12 K Space Stirling mechanical cryocooler. We describe our work in which we modified a 35 K cooler for use at lower temperatures. With this hardware we have attained temperatures below 14 K, and can provide 100 mW of cooling capacity at 16 K for less than 80 watts of input power. As part of

Development of Stirling Cryocooler for Use In Space
1995A cryocooler is designed for the second Bread Board Model (BBM2). This cryocooler is designed to overcome piston stroke shortage in the original Bread Board Model. The new cryocooler increases linear motor force and reduces flow resistance in the connected parts in the compression space. Magnetic bearings are installed to reduce bearing damping forces,

Development of a Long-Life Stirling Cryocooler
2002A Stirling cryocooler for high temperature superconducting devices has been developed. High efficiency and long lifetime are emphasized in the development. Its performance is 6 W at 70 K with 150 W input under 23°C ambient conditions; at 50°C ambient, it produces 5 W at 70 K with 150 W consumption. The mean time before failure for the design is over 40,
