In other embodiments, the locking member 34 can also be designed to be connected to the auxiliary card 20 through other fixing mechanisms, not limited to the above-mentioned guiding groove and rail mechanism, and can also change the supporting member 32 and the locking member 34. The vertical distance between the brackets 30 is fixed to the non-adjacent expansion card 10 and the auxiliary card 20, that is, other expansion cards can be inserted between the expansion card 10 and the auxiliary card 20.

Referring to FIG. 3 and FIG. 4 , the air blower 40 is fixed to the support member 32 through the four screws 42 and the four screw holes 322 of the support member 32 of the bracket 30 during assembly, and the bracket 30 is locked. Guide rail on firmware 34 The 342 is inserted into the guiding slot 22 through the introduction port 222 of the auxiliary card 20, and the clamping mechanism 324 on the supporting member 32 is clamped on the expansion card 10 away from one side of the blocking piece 16. The bracket 30 is moved along the extending direction of the guiding slot 22 of the auxiliary card 20 to align the air outlet of the air blower 40 with the heating element 12 on the expansion card 10, and a bolt (not shown) is transmitted through the auxiliary card 20. The guide groove 22 is threaded into the through hole 344 of the lock member 34 and screwed into a nut 346 to fasten the lock member 34 to the auxiliary card 20.

In the present embodiment, the power of the blower 40 is provided through a power pin on the pin 24 of the auxiliary card 20, that is, the power lead of the blower 40 is connected to the power pin of the pin 24 through a lead 50. In other embodiments, other power pins on the computer motherboard may also be externally connected.

After the expansion card heat sink is assembled with the expansion card 10, it can be inserted into two adjacent expansion card slots corresponding to the computer motherboard. When the computer motherboard is working, the expansion card 10 starts to work. The power pin on the pin 24 of the auxiliary card 20 provides power to the blower 40, and the blower 40 will dissipate the heat generating component on the expansion card 10, which not only improves the performance of the expansion card 10, but also indirectly The performance of other components on the computer motherboard is improved.
