Abstract: A tool for coating a heat-conducting medium on penetrating holes of heat-dissipating fins mainly includes a hollow pipe body. One end of the pipe body has an annular recessed portion. The upper and lower ends of the recessed portion are formed respectively with an annular guiding slope. Further, on the recessed portion, a plurality of outlet holes is distributed in a circumferential manner. A plurality of supporting pillars is formed between adjacent outlet holes. When the tool penetrates into the penetrating holes of the heat-dissipating fins, a user may apply an external force to the other end of the pipe body, so as to cause the heat-conducting medium within the pipe body to overflow via the outlet holes. The overflowing heat-conducting medium fills the annular recessed portion first. Further, during the drawing operation of the tool, the heat-conducting medium is uniformly coated on the inner edge surfaces of the penetrating holes of the heat-dissipating fins, thereby filling the gap between the heat-conducting pipe and the fins.

Abstract translation: 用于在散热片的穿透孔上涂覆导热介质的工具主要包括中空管体。 管体的一端具有环状凹部。 凹部的上下端分别形成有环状的引导斜面。 此外，在凹部上，多个出口孔以圆周方式分布。 在相邻的出口孔之间形成多个支撑柱。 当工具穿透散热片的穿透孔时，使用者可以向管体的另一端施加外力，使得管体内的导热介质经由出口孔溢出 。 溢出的导热介质首先填充环形凹部。 此外，在工具的拉拔操作期间，导热介质均匀地涂覆在散热片的穿透孔的内边缘表面上，从而填充导热管和翅片之间的间隙。
