Embodiment Construction

[0006] Take the fan heat sink in the computer as an example. The original hard plastic or metal fan blades, the connection parts between the fan and the heat sink, the main board, and the casing (chassis) are changed into plastic and rubber respectively. Moreover, the blades of the fan are made of plastic materials with different hardness and properties, so that the root and leeward parts of the blades are made of relatively higher hardness materials, while the windward blades are made of correspondingly lower hardness materials. When designing a new fan, the possible deformation and impact of the fan during operation should be fully considered. Other kinds of rigid or non-rigid material cast in the part can be reinforced if necessary.

Abstract

The invention relates to a fan and an auxiliary system, whose parts comprise but are not limited to a fan blade, a shell, a protective cover, a blade, a bearing, a support and a motor and the like and other whole bodies or portions which are connected with a fan space and are make by a non-rigid material. According to environmental factors which are rotate speed and air density and the like when the fan normally works, the non-rigid material for making and the mechanical properties of the non-rigid material are properly selected, the amplitude of a port of the auxiliary system and the fan which produces a forced vibration is capable of being effectively reduced, the noise which is produced when the fan blade cuts air is capable of being reduced, simultaneously, the non-rigid material is further capable of reducing the vibration which is transported between the fan, a mating system and other portions which are physically connected with the fan and the mating system, and the resonance which is produced by other parts is prevented or reduced.

Description

Technical field [0001] The present invention relates to fans and accessory systems. technical background [0002] At present, during the operation of the fan, the vibration of the fan blade due to cutting air and its own center of mass deviation will generate a lot of noise and propagate vibration outward. At the same time, the motor of the fan and the auxiliary system of the fan (the auxiliary system refers to the components composed of fan blades, casings, protective covers, blades, bearings, brackets, motors, etc.) itself will vibrate accordingly, or transmit the vibration to the space connected to it. other parts. While these vibrations generate noise, they may also have adverse effects on other equipment or components. Moreover, some noise reduction measures such as improving the shape and size of fan blades and adopting soft suspension structures can only reduce the above-mentioned noise sources or isolate vibrations, but cannot well reduce the generation and transmi...
