| 摘 要： | 电子器件和芯片性能的提高带来电路及其芯片的散热问题日益突出，迫切需要开发研究高效的电子冷却系统，蒸汽压缩式制冷被认为是最具应用前景的制冷方式。针对一套用于电子冷却的微型蒸汽压缩制冷系统，在固定制冷负荷为101.4 W时，通过实验研究了制冷剂充注量和毛细管长度的不同匹配对系统压力、蒸发器侧的制冷效果、压缩机功耗及性能系数的影响关系。结果表明：增加充注量或减短毛细管长度都会导致蒸发压力升高，两热沉被冷却至平衡时的表面温度也升高，且压缩机功耗增大，系统性能系数下降。当充注量为120 g、毛细管长度为3 m时，实验系统的整体性能较好，两组热沉温度能维持在约12 ℃不变，压缩机功耗41 W，系统制冷COP能达到2.48。
