Measurement Method of Phase Characteristics for High Frequency Pulse Tube Cryocooler

Abstract:

The phase characteristics of the high frequency pulse tube cryocooler which include the mass flows, the pressure amplitudes, and the phase angles between them significantly affect the cooler performance. A measurement method by using pressure sensors, temperature sensors and linear variable differential transformer rods is presented to evaluate and estimate the phase characteristics for the key components within the cooler such as the compressor, the regenerator, the inertance tube. etc, also the construction method of the phasor diagram based on the measurement is given. The constructed phasor diagram can be used to compare with the design values and provide the optimization direction of the prototype.
