Embodiment 1
[0028] Such as Figure 1 to Figure 5 As shown, a heat conduction device includes a heat conduction block 1 and a heat pipe 2 . One side of the heat conduction block 1 is provided with a heat transfer boss 3 . A cavity 4 is arranged inside the heat conduction block 1 . The cavity 4 is filled with working fluid. Several heat exchange fins 5 are arranged on the inner wall of the cavity 4 near the heat transfer boss 3 . The heat exchange fins 5 are made of aluminum. The heat pipe 2 passes through the heat conduction block 1 . A section of the heat pipe 2 passing through the heat conduction block 1 is close to the cavity 4 .
[0029] The heat conduction block 1 is provided with a filling port 6 . The filling port 6 includes a first filling channel 7 arranged on the heat conduction block 1 . One end of the first filling channel 7 communicates with the cavity 4 , and the other end passes through the heat conducting block 1 . The heat conduction block 1 is provided with a colu...
Embodiment 2
[0032] Such as Figure 6 to Figure 7As shown, the difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the filling port 6 includes a second filling channel 23 , a tapered cavity 24 , a threaded hole 25 , and an elastic body 27 . The second filling channel 23 , the tapered cavity 24 and the threaded hole 25 are all arranged on the heat conducting block 1 . One end of the second filling channel 23 communicates with the cavity 4 , and the other end connects with the tapered cavity 24 . An end of the tapered cavity 24 away from the second filling channel 23 is connected with a threaded hole 25 . The threaded hole 25 passes through the heat conduction block 1 . The elastic body 27 is a cylinder. The elastic body 27 is made of silicone. One end of the elastic body 27 is close to the surface of the tapered cavity 24 , and a threaded sleeve 26 is threaded in the threaded hole 25 . The screw sleeve 26 is cylindrical, and one end of the screw sleeve 26 is close...
