Experimental Study on the Performance Characteristics for the Three Types of the Pulse Tube Refrigerators

맥동관 냉동기의 유형별 성능특성에 관한 실험적 연구

lower vibration than in any other small refrigerators. The experimental results of three types of pulse tube refrigerators are presented in this paper. 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.
