Performance Prediction and Experimental Investigations on Integral Pulse Tube Cryocooler for 15 W at 70 K Using Indigenously Developed Linear Compressor

摘要

Theoretical model based on cyclic analysis has been extended to design the integral pulse tube cryocooler. Cryocooler is developed to match with the indigenously developed opposed piston linear compressor of 30 cc swept volume. The design is carried for the Stirling type Pulse Tube cryocooler to develop 15 W at 70 K. The Pulse Tube cryocooler has been developed with due attention to the heat exchangers and regenerator. Experimental investigations have been carried out for study of the effect of pulse tube aspect ratio and to confirm the consistency of the model and suitability of the linear compressor. Experimental investigation confirmed consistent performance of the linear compressor as well as the Pulse Tube cryocooler.
