Description

Technical Field

[0001] This utility model relates to the field of fan heat dissipation technology, and in particular to a fan heat dissipation and heat conduction structure. Background Technology

[0002] With the continuous development of industrial technology and electronic equipment, fans are being used more and more widely in various systems, and their power and operating load are constantly increasing. During the operation of fans, key components such as motors and controllers generate a lot of heat. If this heat cannot be dissipated in a timely and effective manner, the temperature of the components will rise, which will affect the performance, reliability and service life of the fan.

[0003] However, existing fan cooling structures have the following drawbacks:

[0004] 1. Traditional fan cooling structures often use a single metal material for heat conduction, resulting in delayed heat absorption and transfer, and an inability to quickly respond to the large amounts of heat generated instantaneously by the fan. Furthermore, some structures have poorly designed airflow paths, leading to low air utilization and difficulty in efficiently dissipating heat. Additionally, the air intake structure lacks sufficient dust protection, allowing dust to easily enter the fan and affect its lifespan.

[0005] 2. Traditional fan cooling structures require a variety of tools for cumbersome assembly, which is not only time-consuming and labor-intensive, but also not conducive to later maintenance and replacement. Utility Model Content

The diameter of the honeycomb holes in the air inlet grille 5 is smaller on the outside and larger on the inside. The side of the fan cover 2 has an installation groove 201, and a magnetic ring 6 is installed inside the installation groove 201.

[0030] The aforementioned structure, with its honeycomb-shaped hexagonal air intake grille 5, effectively filters the incoming air, blocking dust and other impurities from entering. The design of smaller outer and larger inner apertures further enhances the dustproof effect while ensuring smooth airflow.

[0031] An air outlet is provided at the bottom of the heat sink 4, a mounting base 8 is installed on the upper surface of the heat sink 4, a fan 7 is installed inside the mounting base 8, and several ventilation slots are provided on the side surface of the mounting base 8.

[0032] A ring of heat dissipation fins 401 is fixedly installed on the upper surface of the heat sink 4. The heat dissipation fins 401 have a spiral structure.

[0033] The surface of the heat dissipation fin 401 is coated with a graphene coating, and a connecting plate 3 is fixedly connected to the upper surface of the heat dissipation fin 401.

[0034] In the above structure, the side surface of the mounting base 8 has several ventilation slots to ensure airflow around the fan 7, which is beneficial for the heat dissipation of the fan 7 itself. A ring of heat dissipation fins 401 is fixedly installed on the upper surface of the heat dissipation plate 4. The heat dissipation fins 401 have a spiral structure, which increases the contact area with air and improves heat dissipation efficiency. The surface of the heat dissipation fins 401 is coated with a graphene coating. Graphene has excellent thermal conductivity, which can further enhance the thermal conductivity of the heat dissipation fins 401.

[0035] The outer surface of the connecting plate 3 has an installation opening, and the fan cover 2 is installed in the installation opening. The inner side surface of the connecting plate 3 is equipped with a second magnet ring 9. The second magnet ring 9 and the first magnet ring 6 are compatible with each other. Both the second magnet ring 9 and the first magnet ring 6 are embedded structures.

[0036] An air inlet is provided on the inner surface of the connecting plate 3, and the air inlet, air outlet, and air inlet grille 5 are opposite each other.

[0037] The connecting plate 3 and the heat sink 4 are made of aluminum and copper composite structure. The internal copper layer and heat sink fins 401 are attached together, and the external structure is an aluminum shell.

[0038] In the above structure, the outer surface of the connecting plate 3 has an installation port, the fan cover 2 is installed in the installation port, and the inner side surface of the connecting plate 3 is equipped with a second magnetic ring 9. The second magnetic ring 9 and the first magnetic ring 6 are compatible with each other. Both the second magnetic ring 9 and the first magnetic ring 6 are embedded structures.

[0040] The connecting plate 3 and the heat sink 4 are made of aluminum and copper composite structure. The internal copper layer and heat sink fins 401 are bonded together, and the external structure is an aluminum shell. Copper has good thermal conductivity and can quickly absorb the heat generated by the fan 7, while the aluminum shell is conducive to heat dissipation. This composite structure improves the overall thermal conductivity and heat dissipation efficiency.

[0041] Working Principle: When the fan 7 is running, the suction force it generates draws outside air in through the air inlet grille 5 on the fan cover 2. The air inlet grille 5 filters the air, blocking dust and other impurities. After passing through the air inlet grille 5, the air enters the heat dissipation body 1 through the air inlet of the connecting plate 3. The heat generated by the fan 7 is quickly absorbed by the copper layer inside the connecting plate 3 and the heat dissipation plate 4. The copper layer transfers the heat to the external aluminum shell and the heat dissipation fins 401 on the heat dissipation plate 4. The graphene coating on the surface of the heat dissipation fins 401 accelerates the heat conduction. Under the action of the fan 7, the air flows inside the heat dissipation body 1, making full contact with the heat dissipation plate 4 and the heat dissipation fins 401. After absorbing heat, the air is discharged from the air outlets around the heat dissipation fins 401, thus achieving effective heat dissipation for the fan 7.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
