Comparative study on the degradation of phenol by a high-voltage pulsed discharge above a liquid surface and under a liquid surface

The degradation of phenol by pulsed discharge plasma above a liquid surface(APDP) and under a liquid surface(UPDP) was compared. The effects of discharge voltage, discharge distance,initial solution conductivity and initial p H on the removal of phenol were studied. It was concluded that the removal of phenol increases with increasing discharge voltage and with decreasing discharge distance in both APDP and UPDP systems. An increase in the initial solution’s conductivity has a positive effect in...     

高温共烧陶瓷微流道工艺特性

功率芯片kW/cm²量级的热流密度给其热管理带来了严峻挑战，液冷微流道散热技术是解决热管理问题的重要研究方向。针对陶瓷封装中的应用需求，对高温共烧陶瓷(HTCC)中微流道工艺特性进行了研究。通过微流道设计、工艺流程设计、制备加工和测试，分析了结构参数对加工质量的影响，明确了微流道与芯片之间的陶瓷体厚度为0.30 mm,微流道宽度应≥0.10 mm,微流道间距需根据不同微流道宽度进行设计，微流道长度为非敏感要素。选择适当的结构参数可保证微流道的成形质量和加工精度，为微流道设计和工程化应用提供参考。
