We designed and constructed a dynamic experimental apparatus to measure the instantaneous velocity and pressure in the multi-bypass pulse tube refrigerator with two-bypass tube. DC-flow phenomena are observed from experimental results. The reasons of multibypass version improved the performance of pulse tube refrigerator were given.
