Only, above-mentioned known radiator fan device 10 is owing to only have single fan 12, and its heat dissipation potential is quite limited.Along with central processing unit (CPU) (CPU) running speed and the heat that produced thereof increase significantly, this known radiator fan device 10 because of obtaining and better radiating efficiency, has been difficult to realistic demand.

Summary of the invention

The purpose of this utility model provides the radiator fan device that a kind of heat dissipation potential is good, radiating efficiency is high.

The utility model comprises housing and plural fan; Housing is provided with the putting chamber of ccontaining plural fan, is respectively equipped with intake grill and exhaust outlet in the putting chamber both sides; The opposite direction running of plural fan just to change clockwise respectively and to reverse counterclockwise.

Wherein:

The fan that is arranged at the clockwise respectively opposite direction running of just changeing and reversing counterclockwise of plural number in the putting chamber is the plural fan of even numbers.

Housing system is made up of lower casing and upper casing; Putting chamber system is arranged on the lower casing, and the putting chamber top is opening-like; Intake grill system is arranged on the upper casing; Upper shell cover places the lower casing top, and is locked on the lower casing by most bolts, is combined into housing.

Housing system is provided with two putting chambers, and is provided with between two putting chambers in order to two putting chambers are separated and becomes the dividing plate of separate space separately.

Housing is provided with most in order to increase the radiating fin of heat diffusion area.

The exhaust outlet of housing is to be to expand outwardly shape.

Housing putting chamber bottom is provided with open-work; Plural fan comprises pedestal respectively, be hubbed at flabellum body and the connection on the pedestal and drive the motor of flabellum body; Each fan is assembled in housing open-work inside with its pedestal, by most retaining screw lockings, and makes flabellum body be positioned at putting chamber inside.

The exhaust outlet of housing joins with the radiator that is arranged at its outside.

Because the utility model comprises housing and plural fan; Housing is provided with the putting chamber of ccontaining plural fan, is respectively equipped with intake grill and exhaust outlet in the putting chamber both sides; The opposite direction running of plural fan just to change clockwise respectively and to reverse counterclockwise.During assembling, the utility model device can be located at host computer inside, and make the radiator of housing exhaust outlet corresponding to central processing unit (CPU); When plural fan is turned round by motoring, can introduce cool air via the intake grill of housing, and cool air be sent by the exhaust outlet of housing, dispel the heat with central processing unit (CPU) and the radiator that is opposite to the exhaust outlet outside; Promptly, can produce bigger air quantity owing to have a plurality of fans, forced draft circulation effectively, heat dissipation potential is preferable, can obtain better radiating efficiency, so applicable to the higher central processing unit (CPU) of heating value; And because of these fan running directions of may command opposite, air-flow can be blowed to the adjacent side of its exhaust outlet when making these fan runnings, be that cool air can be sent by in the middle of the utility model, make cool air can concentrate on the highest neutral position of radiator temperature, so that obtain better radiating efficiency.Heat dissipation potential is good, radiating efficiency is high, thereby reaches the purpose of this utility model.

Embodiment

As Fig. 2, shown in Figure 3, the utility model comprises housing 20 and plural fan 40.

Housing 20 is flat hollow casing, and it is to be made up of lower casing 21 and upper casing 22.

Lower casing 21 is with thermal conductivity good metal material, make as aluminium material etc., which is provided with plural number, as two or four, preferably two is that roughly rounded putting chamber 23, two putting chambers 23 tops of even numbers are opening-like, and two putting chambers, 23 bottoms are respectively equipped with rounded open-work 24, be respectively equipped with in two putting chambers, 23 1 sides and be the exhaust outlet 25 that expands outwardly shape, being provided with in order to two putting chambers 23 are separated in 23 of two putting chambers becomes the dividing plate 26 of separate space separately.Lower casing 21 is provided with most in order to increasing the radiating

fins

27,28 of heat diffusion area, and lower casing 21 tops are provided with most in order to be combined into the attachment hole 29 of screw with upper casing 22.

Upper casing 22 is to make with thermal conductivity good metal plate body, in upper casing 22 be provided with two rounded and with 21 liang of putting chambers of lower casing, 23 corresponding intake grills 30, upper casing 22 be provided with lower casing 21 on attachment hole 29 corresponding attachment holes 31.

Upper casing 22 lid places lower casing 21 tops, and runs through it on attachment hole 31 mutually and spiral shell is located at lower casing 21 for the bolts in the screw attachment hole 29 32 lock by majority, is combined into housing 20.

Be two or four, the plural fan 40 that is preferably two comprises pedestal 41 respectively, be hubbed at the flabellum body 42 on the pedestal 41 and connect and drive the motor of flabellum body 42.

Two fans 40 are assembled in 21 liang of putting chambers of housing 20 lower casings, 23 open-works, 24 inside with its pedestal 41, and are locked on the housing 20 by the pedestal 41 of most retaining screws 43 with two fans 40, and make the flabellum body 42 of two fans 40 be positioned at two putting chambers, 23 inside.Two fans 40 are just to change clockwise respectively and the opposite direction running of counter-rotating counterclockwise, air-flow can be blowed to the adjacent side of two exhaust outlets 14 when making 40 runnings of two fans.
