Description

TECHNICAL FIELD

[0002] Heat dissipation fan is one of the fan types. The fan specifications and sizes range from 8mm to 280mm, and the voltage ranges from 5V, 12V, 24V, 48V, 110V, 220V, 380V, and the shape ranges from square, round, and olive-shaped.

[0003] The existing heat dissipation fan used in the heat generating parts such as chips and high-end electronic devices is generally directly locked to the required position by screws. For example, the existing technology (publication number: CN222719856U, publication date: 2025.04.04) discloses a computer heat sink, and for example, the existing technology (publication number: CN222748942U, publication date: 2025.04.11) discloses a heat sink with a new fan arrangement, and their fans are directly fixed to the heat sink by screws.

[0004] However, the heat dissipation fan will generate vibration to some extent during work. For high-end heat generating devices, the vibration is particularly strong when the fan power is high. The heat generating device needs to work in a vibrating environment for a long time, which affects its service life and causes the equipment to be easily damaged. The common replacement method on the market is to use water cooling for cooling, but the cost of water cooling is higher, and the water cooling pipeline is more prone to damage than air cooling.

[0005] Therefore, it is necessary to design a heat dissipation fan that can significantly reduce vibration transmission for high heat dissipation and low vibration requirements of electronic devices. INVENTION CONTENTS
