Abstract
An object of the utility model is to provide a computer fan of low vibrations low noise, because the utility model discloses between fan blade stator base and frame seat, adopt spring or other elastic material to be connected, stopped the vibrations of fan and passed to quick-witted case through the frame seat and arouse quick-witted case resonance, eliminated the vibration noise of fan, simultaneously the utility model discloses still be equipped with fan rotational speed adjusting device, can be according to radiator temperature automatically regulated fan rotational speed, can suitably reduce the air current noise of fan.
Description
Affiliated technical field
The utility model relates to a kind of computer radiating apparatus, is meant a kind of low hot-tempered sound computer heat radiation fan with spring shock absorption especially.
Background technology
Known computer heat radiation fan, mainly contain fan blade, stator base, skeleton frame composition, generally all be fixed in heating radiator or computer housing during use with self-tapping screw, owing to the reason of making or after using a period of time, the transient equilibrium of fan blade is destroyed, vibrations that produce during rotation and noise are all by heating radiator or be directly conducted to cabinet, when serious even cause cabinet resonance.
Goal of the invention
The purpose of this utility model is to provide the computer fan of a kind of low vibrations, low noise, because the utility model is between fan blade stator base and skeleton frame, the employing resilient material connects, the vibrations of having stopped fan reach cabinet by skeleton frame, eliminated the vibrating noise of fan, the utility model also is provided with temperature control equipment simultaneously, can regulate rotation speed of the fan automatically according to radiator temperature, can suitably reduce the pneumatic noise of fan.
The purpose of this utility model is achieved in that a kind of elastic shock attenuation low noise computer fan, comprise: fan blade, stator base, spring, skeleton frame and rotation speed of the fan auto-adjusting circuit, it is characterized in that adopting spring to substitute the fixed support of known fan, utilize the damping characteristic of spring to vibrations, the vibrations of having stopped to produce when fan blade rotates conduct to housing and other fasteners; Simultaneously, the temperature sensor be close to heating radiator can be according to the temperature controlled fan power source voltage height of heating radiator, thereby reach the purpose that makes fan adjust rotating speed automatically according to need of work.
Description of drawings
Figure one is the structural representation of known computer fan.
Figure two is structure backplan of the present utility model.
Figure three is backplan and circuit connection diagrams of another embodiment of the present utility model.
Figure four is rotation speed of the fan auto-adjusting circuit schematic diagrams of the present utility model.
Embodiment
Below be according to embodiment, further specify of the present utility model:
Embodiment one: figure one, figure two, figure three are structural representations of the present utility model, (1) fan blade, (2) stator base fixed support, (3) skeleton frame, (4) stator base, (5) outer spring hook, (6) inner spring hook, (7) spring.For making fan blade (1) can stably be fixed in skeleton frame (3) central authorities, adopted 3,4 springs among the embodiment respectively, also can adopt more than 4, each bar spring is respectively by corresponding inside and outside spring carrier arm, with the pulling force of self, stator base (4) is fixed in skeleton frame (3) central authorities.Outer spring hook (5) is an outer frame bottom projection at an angle, and the relative direction at middle perforate and housing center has breach; Inner spring hook (6) is the outside projection at an angle of stator base (4), and middle perforate and center direction in opposite directions have breach.
Among this embodiment, do not adopt the rotation speed of the fan regulating circuit.
Embodiment two: figure two, figure three, figure four are structural representations of this embodiment, (3) skeleton frame, (4) stator base, (5) outer spring hook, (6) inner spring hook, (7) spring.Fan structure is described identical with embodiment one, figure four is circuit theory diagrams of rotation speed of the fan auto-adjusting circuit, the E utmost point of power adjustment pipe Q meets power voltage terminal V1 among the figure, C utmost point wind-receiving fan power voltage terminal V2, the B utmost point connects the sliding end of adjustable resistance VR, the end of adjustable resistance VR is connected with power voltage terminal V1 by resistance R, and the other end is connected with power supply ground by temperature sensor Rt, and temperature sensor Rt is close to spreader surface.According to diagram, when radiator temperature was low, the resistance of temperature sensor Rt increased, and the electric current of the adjustment pipe B utmost point of flowing through is less, and the pressure drop of adjusting pipe E, C two ends is big, and fan is lower with lower rotation speed operation because of the voltage that obtains; In like manner, when radiator temperature is high, voltage higher run up of fan because of obtaining.Suitably adjust VR the temperature of rotation speed of the fan and heating radiator is complementary, for example, when radiator temperature is 38 when spending, fan is with 70% running of rated speed, and when radiator temperature is 48 when spending, fan turns round with 95% of rated speed.
Figure three is circuit connection diagrams of the present utility model, (8) fan wiring board, and (9) connect lead, (10) lead fixed hole, (11) speed governing wiring board, (12) fixed orifice, (13) fan power supply plug.Shown in figure three, fan wiring board (8) adopts soft connection lead (9) to be connected with speed governing wiring board (11) through the lead fixed hole, and fan power supply is taken from the respective socket of computer main board by fan power supply plug (13).Speed governing wiring board (11) uses screw fixings in skeleton frame (3) side by fixed orifice (12), and temperature sensor Rt held against heat sink is fixed; Speed governing wiring board (11) also can be fixed with temperature sensor Rt one held against heat sink.
By above scheme, the utility model has improved known computer fan, has reached the purpose that makes the running of the low vibrations of computer fan low noise.
Claims (3)
1. an elastic shock attenuation low noise computer fan comprises skeleton frame, fan blade, stator base, it is characterized in that stator base is fixed in skeleton frame central authorities by several springs.
2. elastic shock attenuation low noise computer fan according to claim 1 also comprises the rotation speed of the fan regulating circuit, it is characterized in that rotation speed of the fan regulating circuit plate is fixed in skeleton frame one side or is fixed in spreader surface with the temperature sensor one.
