制冷剂闪蒸瞬态喷雾冷却表面温度的快速测量

制冷剂闪蒸瞬态喷雾冷却已经成为激光治疗葡萄酒色斑临床手术中重要的冷却辅助手段，能够保护表皮不受激光的热损伤，提高治疗激光能量，改善治疗效果。针对制冷剂闪蒸瞬态喷雾冷却表面温度快速准确测量的难点，建立了制冷剂闪蒸喷雾冷却实验系统，利用磁控溅射技术直接在被测表面沉积T型薄膜热电偶，对薄膜热电偶测量瞬态表面温度技术进行了详细研究，校核了薄膜热电偶的静态温度特性和动态反应时间，对测得的温度结果进行了巴特沃斯低通滤波处理，比较了滤波截止频率和采样率对滤波结果的影响。

Thin-film thermocouples for rapid measurement of transient surface temperature in cryogen spray cooling

Pulsed cryogen spray cooling(CSC) has become an effective method to protect the epidermis from non-specific thermal injuries in laser treatments of vascular malformation such as port wine stains.Cooling experiments with a skin phantom are usually conducted to quantify the heat transfer of CSC from a skin surface.Due to the high cooling ability of CSC and poor thermal conductivity of the skin phantom,the skin surface usually experiences a fast variation of the surface temperatures during CSC.It is therefore ...
