Résumé

A miniature Joule-Thomson (J-T) cryocooler with a spiral finned recuperative heat exchanger is studied in this paper, based on the Visual Basic development platform employing finite difference method. Physical areas were divided according to the different characteristics of flow and heat transfer base on the structure of J-T cryocooler. Steady-state calculation model of J-T cryocooler using argon as working fluid was built through the equations of pressure drop and heat transfer in different physical areas. Calculation programs were developed, and the thermo-physical properties of working fluid can be dynamic updating though invoking the argon database. The influence of inlet gas parameters and surroundings temperature on the performance of argon J-T cryocooler is analyzed. The results of the investigation are useful for the structure optimization of J-T cryocooler, the improvement of its refrigeration effect, the cost reducing. The work of this paper provides reference to the design and application of argon J-T cryocooler.
