本實驗主要針對低溫史特靈引擎再生器之材料與厚度進行研究，實驗中再生器類型選用滑塊型。引擎整體尺寸為120 mm × 120 mm × 165 mm，重量為380克，掃氣活塞尺寸大小為94 mm。研究中加熱方式採用電子式加熱器，冷凝方式採用自然對流，輸入功率為5 W、10 W、15 W，環境溫度為28±1℃，操作溫度為52℃至108℃。 再生器材料方面，選用活性碳濾網與珍珠板。實驗結果指出，當輸入相同功率下，以珍珠板為再生器材料之低溫史特靈引擎所輸出之轉速較高。厚度實驗部分，只針對珍珠板為再生器材料，厚度為1 mm至7 mm，實驗中量測低溫史特靈引擎所輸出之轉速來進行比較。相同功率下，引擎轉速隨著厚度增加而變快，而最佳厚度尺寸為6 mm。 The focus attention in this research is on the material and thickness of Low-Temperature Differential Stirling engine regenerator. The displacer regenerator was chosen. The activated carbon filter and formcores were chosen as the regenerator material. The dimension of the engine is 120 mm × 120 mm × 165 mm；the weight of the engine is 380 grams；the dimension of the displacer is 94 mm. Electron heater was adopted for heating；natural convection was adopted for cooling；the range of input power was 5 W, 10 W and 15 W；environment temperature was 28±1℃；operation temperature was 52℃ to 108℃. The range of formcore thickness is 1 mm to 7 mm. Engine speed was measured with different regenerator material and thickness. The research indicates that engine speed with formcore regenerator is faster than activated carbon filter regenerator. The increase of engine speed is caused by the increase of the thickness. The best thickness is 6 mm.
