Abstract
The invention discloses a server based on bladeless silent fans and a noise reduction method. Blade fans in the positions where fans are mounted at the front end of the server are replaced with the bladeless silent fans, panel air inlet hole filter nets are replaced with casings made of the same material as the server, a plurality of air inlet holes are formed in the bottom end of a server panel, original air inlets are sealed, and the sound insulation function is performed. Airflow of the fans is uniform and flows in the same direction, accordingly, friction is very small, noise can be substantially reduced, most of the area of a front panel is sealed, a large filter is not required, a good sound insulation function is performed, and the noise reduction effect of the server is very remarkable under the double actions.
Description
Technical field
The present invention relates to server noise reduction technology field, be specifically related to a kind of based on without the server of leaf quiet fan and the method for noise reduction.
Background technology
Along with the computing capability of computer is required more and more universal by people, in the case of more and more higher, server or large-scale PC work station more and more obtain the purchase of small enterprise or individual and use, but these enterprises or individual seldom have independent space to remove to dispose these equipment, but the high noisy pollution that these equipment bring almost is difficult to allow them be placed in the middle of working environment.
Traditional method is to be provided with fan-leaf fan in server front end, it is used for dispelling the heat to server internal, but the server of generally large power be equipped with multiple rotating speed the highest have fan-leaf fan (such as blade server), such server is when start runs, multiple fan cooperation cutting air, server internal is caused to produce a large amount of random air-flows, these air-flow phase mutual friction can bring the biggest noise, designs and this can eliminate this not convenient property based on the server noise-reduction method without fan-leaf fan.
Summary of the invention
The technical problem to be solved in the present invention is: in place of the present invention is directed to the deficiencies in the prior art, it is provided that a kind of based on without the server of leaf quiet fan and the method for noise reduction.
The technical solution adopted in the present invention is:
A kind of method based on the server noise reduction without leaf quiet fan, the position installing fan in server front end will have fan-leaf fan to be changed to without flabellum quiet fan, and change panel fresh air inlet filter screen into server with material shell, make the mildest output in the same direction of air without fan-leaf fan by using thus reduce severe friction between air, reduce noise, and air inlet without fan-leaf fan is the least, only have 1/the tens of blade fan, need not opening as traditional server air inlet huge, occupy server panel major part space, as long as and output multiple fresh air inlet in bottom, former air inlet is shut and is played good deadening.
A kind of based on the server without leaf quiet fan, the structure of described server includes the quiet fan without flabellum being installed on server front end, the structure of described quiet fan without flabellum includes fan head and fresh air inlet and intake stack, fresh air inlet is arranged at the bottom of server front end panel, fan head is provided with fan mouth, it is connected by intake stack between fan mouth and fresh air inlet, intake stack is provided with cyclone accelerator, air is entered inside intake stack by fresh air inlet, after accelerating via cyclone accelerator, air passage rates increases to tens times.
Described fan mouth is annular, and the air-flow after acceleration is sprayed with circular trace by annular fan mouth, and the fan mouth of annular improves jet-impingement speed, expands the area of jet-impingement, it is possible to preferably promotes ventilation effect.
The structure of described fan head is made up of the housing of outer layer and the annular epipharynx of internal layer, fan mouth is positioned at the bottom of annular epipharynx, fan mouth position is provided with guide vane, air-flow annularly epipharynx is guided to spray with cyclone mode, the when of vortex gas-flow ejection, the air near fan mouth can be driven to enter fan head therewith, and blow out the most backward, uniformly and in the same direction cause because of air-flow rubbing each other the least, noise can significantly reduce, and front panel major part area is shut, large-scale filter screen is no longer had to play good deadening, server noise reduction can be made clearly under two aspect effects.
Described fan head, intake stack are individually fixed in server machine chamber interior wall, the air inlet of each quiet fan without leaf is several, scattering device is in cabinet panel lower end, each air inlet is connected to intake stack by a tiny pipeline, parts due to whole fan: fan head, intake stack is individually fixed in cabinet inwall, adds the foundation area with cabinet, fully reduces the noise caused because of fan vibration.
The invention have the benefit that
The present invention can allow fan airstream uniformly and in the same direction cause rubbing each other the least, and noise can significantly reduce, and front panel major part area is shut, and no longer has large-scale filter screen to play good deadening, can make server noise reduction clearly under two aspect effects.
Accompanying drawing explanation
Fig. 1 is that schematic diagram arranged by server front end fan of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, according to detailed description of the invention, the present invention is further described:
