Description

Technical Field

[0001] This utility model relates to the field of heat sinks, and in particular to heat dissipation modules. Background Technology

[0002] Components generate a lot of heat when they are working. If this heat is not dissipated in time, it can cause system crashes or even burn out the components. Component heat sinks are used to dissipate heat from components. However, the fans on existing heat sinks are fixed to the heat sink with fan mounts and fixing accessories, resulting in a stacked state on the heat sink. This makes disassembly and assembly inconvenient, and the assembled heat sink is also bulky. Furthermore, since the fans are fixed to the fan mounts with fixing accessories, if the fans are damaged, the entire fan mount needs to be replaced, which is wasteful. Therefore, a heat dissipation module is proposed. Utility Model Content

These connecting parts are distributed at the four corners of the heat dissipation fin surface. A fan is rotatably mounted on the upper end of the fan mounting bracket. The fan can rotate on the heat dissipation fins via the fan mounting bracket. When the heat dissipation fins dissipate heat from the components, the fan can diffuse the heat dissipated by the heat dissipation fins into the surrounding air. Through the detachable and detachable engagement between the fan mounting bracket and the connecting parts, the fan mounting bracket and the fan can be snapped onto the heat dissipation fins.

[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 Figure 1-6 In this embodiment of the utility model, the heat dissipation module includes a base plate 12. A heat dissipation fin 1 for dissipating heat from components is provided at the upper end of the base plate 12. A fan mounting bracket 6 is provided on the heat dissipation fin 1. The heat dissipation fin 1 is also provided with a connecting part that can be detached and assembled with the fan mounting bracket 6. The connecting parts are distributed at the four corners of the surface of the heat dissipation fin 1. A fan 2 is rotatably mounted on the upper end of the fan mounting bracket 6. The fan 2 can rotate on the heat dissipation fin 1 through the fan mounting bracket 6. When the heat dissipation fin 1 dissipates the heat emitted by the components, the fan 2 can diffuse the heat emitted by the heat dissipation fin 1 into the surrounding air. Through the detachable and assembled cooperation between the fan mounting bracket 6 and the connecting part, the fan mounting bracket 6 and the fan 2 can be snapped onto the heat dissipation fin 1, making the installation more convenient and time-saving.

[0023] The connecting portion includes a first protrusion 8 formed on the heat dissipation fin 1, a second protrusion 9 opposite to the first protrusion 8, and a gap (not shown in the figure) formed between the first protrusion 8 and the second protrusion 9. The fan mounting bracket 6 has a connecting rod (not shown in the figure) formed therein that is fitted into the gap. A first limiting block 10 is formed on one side of the first protrusion 8 to confine the connecting rod within the gap, and a second limiting block 11 is formed on one side of the second protrusion 9 to confine the connecting rod within the gap, opposite to the first limiting block 10. The first limiting block 10 and the second limiting block 11 are laterally staggered on both sides of the gap. Both the first limiting block 10 and the second limiting block 11 are made of plastic, allowing the fan to... When the fan mounting bracket 6 is installed on the heat sink fin 1 and the connecting rod is engaged in the gap between the first protrusion 8 and the second protrusion 9, the connecting rod will pass through the staggered first limiting block 10 and second limiting block 11, falling into the bottom of the gap. During this process, due to the physical properties of the materials of the first limiting block 10 and the second limiting block 11, the first limiting block 10 and the second limiting block 11 will deform when the connecting rod passes through. When the connecting rod has completely passed through and fallen into the bottom of the gap, the first limiting block 10 and the second limiting block 11 will return to their original shape and be horizontally supported on the connecting rod, thereby blocking and limiting the connecting rod, so that the fan mounting bracket 6 can be installed on the heat sink fin 1 together with the fan 2.

[0024] A heat pipe 3 is provided between the base plate 12 and the heat dissipation fins 1, with one end of the heat pipe 3 located at the bottom end of the base plate 12 and the other end of the heat pipe 3 inserted into the heat dissipation fins 1. The base plate 12 is either an aluminum base plate or a copper base plate.

[0025] The base plate 12 is provided with a first slot 14 for fixing one end of the heat pipe 3. The first slot 14 is formed at the bottom end of the base plate 12 and arches upward. One end of the heat pipe 3 is inserted into the first slot 14. The end of the heat pipe 3 is pressed so that its end face is at the same level as the bottom surface of the base plate 12 and the end of the heat pipe 3 can be fastened into the first slot 14. Thus, when the base plate 12 and the heat dissipation fins 1 are installed on the component, one end of the heat pipe 3 can be attached to the component. This allows the heat generated by the component during operation to be conducted and dissipated through the cooperation between the heat pipe 3, the heat dissipation fins 1 and the fan 2, thereby achieving heat dissipation.

[0026] The heat dissipation fin 1 is provided with a channel 7 for limiting the installation of the other end of the heat pipe 3, and the channel 7 is formed inside the heat dissipation fin 1, and the other end of the heat pipe 3 is inserted into the channel 7.

[0027] The bottom surface of the base plate 12 is provided with brackets 4 on both sides to mount the heat sink 1 and the fan 2 onto the components. The brackets 4 are provided with first fixing screws 5, and the first fixing screws 5 are all vertically located at the four corners of the brackets 4. The brackets 4 are also provided with washers 13 horizontally. Thus, the brackets 4 and the base plate 12 can be fixed to the components to be cooled by the first fixing screws 5, and the washers 13 prevent the components from being scratched when the brackets 4 and the base plate 12 are fixed to the components to be cooled.

[0028] The bottom surface of the base plate 12 is provided with second slots 16 on both sides for mounting and fixing the bracket 4. The support bracket 4 is provided with second fixing screws 15 to fix it together with the base plate 12 to the bottom surface of the heat dissipation fin 1. The second fixing screws 15 pass through the second slots 16, and the second slots 16 are formed with through holes 17 for the second fixing screws 15 to pass through.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
