Abstract
The utility model discloses a kind of turbo type height rotating speed fan assembly, its structure comprises turbofan, blast fan, power supply interface, intake grill, exhaust outlet, turbosupercharging room, turbofan is positioned at fan neutral position, described blast fan is arranged in turbosupercharging room, described turbosupercharging room is annular, and the annular cross-sectional area be connected with exhaust outlet is greater than the section area away from exhaust outlet one end.The utility model reasonable in design, noise is little, and wind-force is powerful, and fast, turbofan is located at neutral position, outer surface on-bladed simultaneously, safe and reliable, and appearance is smooth surface, easily cleans in heat radiation.
Description
Technical field
The utility model relates to a kind of turbo type height rotating speed fan assembly.
Background technique
Fan refers to that hot day gets cool apparatus electric fan so as to raw wind, is the device producing air-flow by electric drive, and the fan energising of interior configuration was carried out rotating the effect changing into natural wind to reach and enjoy the cool afterwards.
Conventional fan is the one of axial fan, and motor position air-flow cannot pass, and therefore center airless has " blind area ", and air stream turbulence is more serious.The heat radiation of central position is bad.
The another name of centrifugal fan, is common in PC field of radiating, is accustomed to small-sized centrifugal cutter to be called turbofan.The gas flow of turbofan is perpendicular to rotating shaft, and common axial fan gas flow and shaft parallel.
Relatively traditional radiation fan, centrifugal cutter can export larger air quantity, improving radiating effect under less space hold.But the machining accuracy of centrifugal blower flabellum comparatively conventional fan requires higher, and the noise sent when impeller has dust stratification or runs up is also larger.Now along with the decline of CPU power consumption, CPU turbofan gradually replace by the common axial flow quiet fan of the bigbore slow-speed of revolution, but still often to use on the especially public version graphic card radiator of high performance video cards.
Centrifugal fan is by driven by motor vane rotary, blade in impeller forces gas rotating, to air work, its momentum is increased, and gas under the influence of centrifugal force, throw away to impeller surrounding, convert kinetic energy to pressure energy by whirlpool type casing, after the gas in impeller is discharged, the pressure in impeller is lower than air intake pipe internal pressure, new gas is intake impeller under the effect of pressure difference, and gas is just continuously discharged in fan.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of turbo type height rotating speed fan assembly.
The technological scheme that the utility model adopts is:
A kind of turbo type height rotating speed fan assembly, its structure comprises turbofan, blast fan, power supply interface, intake grill, exhaust outlet, turbosupercharging room, turbofan is positioned at fan neutral position, described blast fan is arranged in turbosupercharging room, described turbosupercharging room is annular, and the annular cross-sectional area be connected with exhaust outlet is greater than the section area away from exhaust outlet one end.The design that turbosupercharging room is up-small and down-big, can increase the raising of wind speed, makes the wind-force sent more powerful.
Described exhaust outlet tangentially position is arranged at the excircle place of turbosupercharging room, cross section is rectangular, be provided with grooved exhaust outlet in exhaust outlet, described grooved exhaust outlet is the cylindrical structure that some guide vanes are vertically formed, the corresponding air guide hole setting direction in the direction that each guide vane plane is arranged.The air quantity of exhaust outlet can be made so even, and air-supply is stable.
Described wind inlet of fan position is provided with some intake grill guide vanes.The air output of intake grill can be made like this to keep evenly, avoiding the vibration caused because air output is uneven, produce noise.
The beneficial effects of the utility model are: the utility model reasonable in design, and noise is little, and wind-force is powerful, and fast, turbofan is located at neutral position, outer surface on-bladed simultaneously, safe and reliable, and appearance is smooth surface, easily cleans in heat radiation.
