In actual implementation, the water-cooled heat sink 1 may include a shell 2. The shell 2 covers the upper shell seat 30 and is combined on the lower shell seat 10. The water-cooled heat sink 1 is described in more detail as follows.

[0059] The lower shell seat 10 includes a heat exchange space 11, a water collection space 12, and a connecting port 13 connecting the heat exchange space 11 and the water collection space 12.

In this embodiment, the water cooling plate assembly 20 includes a guide plate 21 and a plurality of fins 22 disposed on the guide plate 21, and the plurality of fins 22 are located in the heat exchange space 11.

[0061] The upper housing 30 includes an outer installation space 31 and an inner installation space 32 that are separated. The upper housing 30 is provided with a plurality of second threads 33, and is coupled to the lower housing 10 by screwing the plurality of second threads 33 and the plurality of first threads 15 together.
