中文摘要 本研究主要製作設計脈衝管式史特靈冷凍機,並且建立可預測冷凍機之理論模型與原型機開發。理論模型將冷凍機分成七個腔室,分別為壓縮室、冷卻器、再生器、製冷頭、脈衝管、次級冷卻器以及儲氣室,藉由初始條件求得汽缸內部體積變化量以及改變腔室之壓力,接著求得各個腔室中熱力性質後,將系統因內部產生的損失之影響代入能量方程式,計算出各腔室溫度變化及製冷頭無負載溫度,再藉由建立之理論模型進行參數分析並且觀察各項參數對製冷頭溫度之影響。本研究所開發之脈衝管式史特靈冷凍機於填充壓力為5 atm、工作流體為氦氣、慣性管長度為3公尺、脈衝管長度為15公分、儲氣室體積為1公升、操作頻率為35 Hz之條件下,可獲得無負載之製冷頭溫度為215 K;於相同條件下進行熱負載實驗量測,可獲得在平衡溫度240 K時2.0 W製冷量,性能係數為0.037。
英文摘要 This thesis is aimed to develop a pulse-tube Stirling cooler, and to build a thermodynamic model to predict the cooler’s performance. In the thermodynamic model, the cooler is divided into seven chambers for analysis, namely compressor, cooler, regenerator, cold head, pulse-tube, second cooler and reservoir. In the model, effects of the pressure losses and heat losses are considered. Instantaneous temperatures, heat transfer rates, temperatures, masses and pressures of air in all the chambers are predicted. A prototype cooler using helium as the working gas is developed, which is able to achieve a zero-loading temperature of 215K at operating frequency of 35Hz and charged 5 atm.
