Abstract
本发明公开了一种冷却装置及光纤式叶尖定时传感器，冷却装置包括：主体，第一端用于与待测件匹配连接；第一端端部沿轴向开设安装孔，主体具有第一内腔，用于穿设光纤本体并使光纤本体的探头的端部穿设于安装孔，主体的第一端的端部还设置冷却构造；转接件，用于与主体的第二端可拆卸连接，具有第二内腔，用于穿设光纤本体以及冷却管，冷却管用于连接外部气源以将冷却气经冷却构造输出至光纤本体的探头的端部；密封组件，用于密封转接件并使冷却管的两端分别与外部与第一内腔连通。当传感器端面出现油雾污染时，通过将装置主体与转接盘拆卸，用清洗剂如酒精灯对光纤探头及主体的第一端端部进行全面的清洗擦拭；当光纤本体出现损坏时，同样可通过拆除密封组件及连接件的方式分解整个冷却装置，取出光纤本体进行维修或更换，然后重新装配，本装置结构精简、操作简便，可重复拆解装配，显著提高了实际测试过程中的工作效率。
