Description
A single-stage coaxial pulse tube cryocooler (PTC) has been designed, manufactured and tested at Shanghai Institute of Technical Physics (SITP), Chinese Academy of Sciences (CAS) for cooling an aerospace low temperature refrigerator (LTR) whose cooling volume is 20 liters. An experimental setup has been designed and fabricated and some experimental investigations have been carried out and analyzed after the PTC is coupled with the LTR. The results show that the PTC is capable of cooling the LTR down to173K around in a few hours and the input power is only 135W DC. The LTR system and the PTC are introduced respectively. In addition, the LTR cooling curve has also been presented and investigated in detail for a thorough understanding of this cooling system.
