For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
The described fan of the utility model specific embodiment, be arranged to few two exhaust outlets by housing side at fan, increase the quantity of exhaust outlet, make different exhaust outlets can take into account the interior different heat element of electronic equipment simultaneously, to its heat radiation, thereby can reach the purpose that improves radiating efficiency in the electronic equipment.
Below will the structure of the described fan of the utility model specific embodiment be described in detail.
The described fan of the utility model specific embodiment comprises:
Can be around a plurality of flabellums of stationary axle rotation;
Housing comprises:
One holding space, described flabellum are arranged in the described holding space;
Produce the intake grill of the described holding space of distinguished and admirable inflow when being used to described flabellum is rotated;
At least two exhaust outlets that are used to make the described holding space of described distinguished and admirable outflow.
Fig. 2 is the schematic appearance of the described fan of the utility model first embodiment, and Fig. 3 is the decomposing schematic representation of the described fan of the utility model first embodiment.In conjunction with consulting Fig. 2 and Fig. 3, this fan 10 specifically comprises:
Produce when flabellum 12 is rotated flow distinguished and admirable, the housing 11 of fan 10 is provided with intake grill and exhaust outlet, by intake grill and exhaust outlet, make the external communications of holding space and housing 11, and then when flabellum 12 rotates, cause the outside air disturbance, produce rough air flows into fan 10 from intake grill holding space, after flabellum 12 pressurizations through rotating, by the holding space of exhaust outlet outflow fan 10, can be with thinking that the heater element in the electronic equipment dispels the heat.
In order to make the distinguished and admirable of fan 10 can take into account a plurality of heater elements simultaneously, be a plurality of heater element heat radiations simultaneously, according to the placement position of each heater element in the electronic equipment, a plurality of exhaust outlets of suitable size are offered in the appropriate location on fan 10.
In the utility model specific embodiment, described fan 10 forms the blower fan, also promptly forms air inlet through hollow shaft, the form of air-out radially.As Fig. 2, the intake grill 14 of fan 10 is to be arranged on the vertical surface 111 of housing 11 and stationary axle 13, and exhaust outlet is arranged on housing 11 and surperficial 111 side surfaces that intersect, even also exhaust outlet to the connecting line of stationary axle 13 is positioned at the radial direction of fan 10, constitute radially air-out form along fan 10.
Consult Fig. 3, on housing 11, a side surface that intersects with surface 111 comprises barrel surface 112 and plane surface 113, wherein whole plane surface 113 is provided with opening, form first exhaust outlet 15, on barrel surface 112, also be provided with an opening, form second exhaust outlet 16.
By above-mentioned set-up mode, the opening that makes first exhaust outlet 15 is towards first direction, and the opening of second exhaust outlet 16 is towards second direction, and first direction is different with second direction.
And in the utility model specific embodiment, the area of first exhaust outlet 15 is far longer than the area of second exhaust outlet 16, first exhaust outlet 15 constitutes main exhaust outlet, produce distinguished and admirable flow field structure schematic representation as fan as described in Fig. 4 first embodiment 10, first exhaust outlet 15 produces air-flow and blows out perpendicular to plane surface 113, most of air-flow that fan 10 is produced is used for the heat radiation of critical piece such as central processing unit (CPU), the fraction air communication is crossed second exhaust outlet 16 and is flowed out, as Fig. 4, second exhaust outlet 16 produces air-flows along blowing out with the tangent direction (also promptly along tangent direction of flabellum 12 slewing circles week) of barrel surface 112, be used for the heat radiation of some heater elements of central processing unit (CPU) periphery, as be used to various field effect transistors (metal-oxide-semiconductor) heat radiation on the mainboard.
When on the described fan 10 second exhaust outlet 16 being set, be used for heat radiation in order to make second exhaust outlet 16 can blow out air-flow, this second exhaust outlet 16 should be arranged at the position that fan 10 horizontal radial directions and housing 11 intersects, this is because flabellum 12 is when stationary axle 13 rotates, in the holding space of housing 11, produce air-flow around stationary axle 13 rotations, when second exhaust outlet 16 is positioned at the position that fan 10 radial direction intersect, the swirling eddy that produces can constantly flow to this second exhaust outlet 16, blow out the continuous air-flow of radially air-out and flow.
In the utility model specific embodiment, best, fan 10 comprises barrel surface 112, to adapt to the flow direction of housing 11 swirling eddies that holding space is produced, can not produce flow-disturbing, based on above-mentioned, blow out radially air-out and the continuous air-flow of flow for making second exhaust outlet 16,16 of second exhaust outlets should be arranged on the barrel surface 112.Barrel surface 112 be provided with position and openings of sizes then need the heater element that dispels the heat as required the position is set and radiating requirements is determined, make second exhaust outlet 16 blow out air-flow and can have influence on this heater element, with to this heater element heat radiation.
Therefore, adopt the described fan 10 of the utility model specific embodiment, can utilize a fan 10 to be used to a plurality of heater element heat radiations, reach the effect of saving heat-dissipating space and heat radiation cost, especially be applied to the system of a plurality of heater elements in the little space, during as notebook computer, integrated machine formula computer, effect is more remarkable.
In addition, the utility model also provides second embodiment's fan 10, as shown in Figure 5, and in a second embodiment, housing 11 in the fan 10, flabellum 12, intake grill 14, first exhaust outlet 15 and second exhaust outlet 16 have the structure identical with first embodiment's fan 10, are not described in detail at this.
Different with first embodiment is, in the described fan 10 of second embodiment, also be provided with a guide vane 17 in the holding space of housing 11, be fixedly set on the housing 11, be used to play guide functions, make flabellum 12 rotate first distinguished and admirable distinguished and admirable guiding first exhaust outlet 15 that produces, second distinguished and admirable distinguished and admirable guiding second exhaust outlet 16 that produces, controlling the distinguished and admirable flow of second exhaust outlet 16, and make the distinguished and admirable more even of first exhaust outlet 15.
Consult Fig. 5, best, guide vane 17 forms the sheet structure of circular arc, and be arranged at described second exhaust outlet 16 places, being positioned at stationary axle 13 is on the circumference in the center of circle, towards stationary axle 13 bendings, like this, by guide vane 17 with respect to the crooked radian of second exhaust outlet 16 with the different of position are set, regulate the distinguished and admirable flow that flows to second exhaust outlet 16, make first exhaust outlet 15 distinguished and admirable evenly.
When for fan 10 as described in the utility model second embodiment guide vane 17 being set as Fig. 6, produce distinguished and admirable flow field structure schematic representation, by comparing with Fig. 4, as can be seen, more even by guide vane 17 being set, making the win flow of exhaust outlet 15, can not influence the radiating effect of main exhaust outlet because of the setting of second exhaust outlet 16.
It will be appreciated by those skilled in the art that, according to design principle of the present utility model, described exhaust outlet to be provided with that number is not limited to be two, on fan 10, be provided with first exhaust outlet (main exhaust outlet) 15, can be as required, on the barrel surface 112 of fan 10, offer a plurality of exhaust outlets, play the effect that heat radiation is dispelled the heat simultaneously to the diverse location heater element.
