Thereby, by the movement of the second pulley 22 on the slide rail structure 6, the heat sink 5 can be carried to a position where it is required to be installed, or the heat sink 5 which needs to be replaced can be removed.

Optionally, as shown in fig. 3, the replacing device further includes a supporting frame 8, the supporting frame 8 is mounted on the heat sink bracket 4, and the supporting frame 8 is used for mounting the sliding rail structure 6. Thereby, the rail structure 6 is attached to the radiator support 4 via the support bracket 8. As shown in fig. 4, one end of the supporting frame 8 is mounted on the heat sink bracket 4, and the other end of the supporting frame 8 is suspended for mounting the sliding rail structure 6.
