[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 A heat dissipation connection structure for an aluminum water-cooled plate includes a water-cooled plate body 1, a connection plate 2 for connecting external hardware, and a connecting circular hole 3 passing through the connection plate.

[0023] Multiple wing plates 4 are formed circumferentially on the inner wall of the connecting circular hole 3. The length direction of the wing plates 4 is the same as the axis of the connecting circular hole 3, and the width direction of the wing plates 4 is the same as the axis of the connecting circular hole 3. There is a connecting space 5 between adjacent wing plates corresponding to the length direction of the connecting circular hole 3.

[0024] The wing plate 4 has a proximal side formed on the inner wall of the connecting circular hole 3 in the width direction, and a distal side close to the axis of the connecting circular hole 3. A shaft hole 6 is formed around the distal side of the plurality of wing plates, and the length direction of the shaft hole 6 is the same as the length direction of the connecting circular hole 3.

[0025] In this embodiment, a connecting pipe 7 is provided through the shaft hole 6, and a connecting bolt 8 and a connecting nut are also provided. The shank of the connecting bolt 8 passes through the connecting pipe 7, and the connecting nut is screwed to the threaded section of the shank that passes through the connecting pipe. The connecting nut is fastened to the connecting pipe 7 by cooperating with the cap of the connecting bolt 8.

[0026] The width of the connecting nut is greater than the width of the shaft hole, and the width of the connecting nut is less than the width (radial diameter) of the connecting hole. The width of the head of the connecting bolt is greater than the width of the shaft hole, and the width of the head of the connecting bolt is less than the width of the connecting hole. This design ensures that, while meeting the anti-loosening requirements, at least one end of the connecting space is not completely blocked.

[0027] When external hardware needs to be connected to the water-cooled plate body 1, the design of connecting nuts, connecting bolts 8, connecting pipes 7 and multiple wing plates 4 is used. Multiple wing plates 7 support the connecting pipes 7, and the rods of the connecting bolts 8 are inserted into the connecting holes of the corresponding hardware, and the hardware is fixed to the connecting pipes 7 in conjunction with the connecting nuts.

[0028] After connecting external hardware, the multiple wing plates 4 and the connecting space 5 formed by the wing plates 4 can form an additional heat dissipation structure on the aluminum water-cooled plate, thereby further improving the heat dissipation capacity of the aluminum water-cooled plate while still allowing for the connection of external hardware.

[0030] A limiting member 9 corresponding to the communicating space 5 is formed on the outer wall of the connecting pipe 7. When the connecting pipe 7 is inserted into the shaft hole 6 along its length direction, the limiting member 9 is inserted into the communicating space 5 from one end opening.

A heat dissipation gap exists between the limiting member 9 and the inner wall of the connecting circular hole 3. Through the design of the limiting member 9, the connecting pipe 7 and the limiting member 9 can also form a reinforced structure to enhance the damage resistance of the wing plate 4, making the wing plate less susceptible to damage.

[0032] Preferably, the outer wall of the connecting pipe 7 is formed with a plurality of limiting members 9 corresponding to a plurality of communicating spaces.

[0033] In some embodiments, the far side of the wing plate 4 is formed with a concave arc-shaped surface, wherein the dot of the arc-shaped surface is on the axis of the connecting hole, so that the shaft hole 6 has an arc-shaped inner wall. After the connecting pipe 7 is inserted into the shaft hole, the arc-shaped inner wall can better support the connecting pipe 7.
