Double Inlet 맥동관 냉동기의 성능특성 실험에 관한 연구

The experimental results of three types of pulse tube refrigerators are presented in this paper. The pulse tube refrigerator, which has no moving parts at its cold section, is attractive for obtaining higher reliability, simpler construction and lower vibration than in any other small refrigerators. The objectives of this study are to develop the design technology of the double inlet pulse tube refrigerator and acquire its application method. As a preliminary experiment, the refrigeration performances of the basic, orifice and double inlet pulse tube refrigerator were investigated. The lowest temperature obtained in this experiment was 34.4K. The refrigeration capacity at the optimum operating condition of the double inlet pulse tube refrigerator was 23W at 80K.
