Abstract
An axial-flow radiating fan is applied mainly in the mainframe of a computer, which consists of a housing and a fan wheel, wherein above and below the housing are provided with an air entrance, an air exit, a diversion frame and an electromagnetic induction stator. On the diversion frame are provided with diversion blades axially with unclose arrangement as well as the outer rim of the wheel hub of the fan wheel are provided with a plurality of fan blades and the inner rim are immovably provided with an electromagnetic induction stator and a rotary axis. The rotary axis is centrally arranged in the bearing in the centre of the housing and in the diversion frame. Therefore, apart from the air charging and discharging from the upper part of the housing, the space among the diversion blades of the diversion frame can increase the air charging volume for the axial-flow radiating fan so as to improve the working efficiency of the axial-flow radiating fan, prolong the service life and lower noise.
Description
Technical field
The utility model relates to radiation fan, especially refer to a kind of set firmly on the water conservancy diversion frame of axial-flow type radiator fan device be the guide vane that axially and does not connect airtight arrangement, can increase air output or reduce the fan revolution, to promote the axial-flow type radiator fan of fan running efficient, working life and reduction noise.
Background technique
Computer has been the equipment of quite popularizing, yet general user can run into a problem usually when using a computer, it also is the general computer manufacturing problem that manufacturer faced, can produce the too high problem of system temperature when especially this computer is carried out a lot of application programs or driven too much peripheral electronic equipment, usually such high temperature heat source is the heat that electrical assembly produced on the machine plate, and continuous lifting along with CPU usefulness and processing rate, along with and the heat dissipation problem that comes just seems important more, so how with heat that electrical assembly produced, the running that relies on fan has become an important topic to produce bigger air output.
Please refer to shown in Figure 1ly, the known axial-flow type radiator fan of using on general electronics or the computer installation mainly comprises: a housing 100 and an impeller 200; , respectively being provided with intake grill 101 and exhaust outlet 102 on the relative position of this housing 100, housing 130, central authorities that four end limits of this housing 100 are installed with fixed via 131 are fixed with electromagnetic induction stator (not shown); Be installed with several fan blade 220 on the wheel hub 210 of this impeller 200, be installed with electromagnetic induction rotor (not shown) in this wheel hub 210, and be provided with the rotating shaft (not shown) in the middle of this wheel hub 210; The rotating shaft of this impeller 200 is installed in the bearing of electromagnetic induction stator of housing 100; After the energising, this electromagnetic induction stator drives the rotation of electromagnetic induction rotor by electromagnetic induction, promptly drives this impeller 200 and rotates, and forces the axial flow of air along axial-flow type radiator fan, and electronics or electrical installations are dispelled the heat.Though, the housing 100 of the known axial-flow type radiator fan of this kind is one-body molded, simple and compact for structure, low cost of manufacture, but, its intake grill 101 and exhaust outlet 102, can only corresponding be arranged at the upper and lower of this axial-flow type radiator fan, under certain fan revolution, limit the air quantity of this axial-flow type radiator fan.Therefore, just have only and increase the fan revolution as increasing air quantity, but as increase the fan revolution and will inevitably increase noise and vibration, this is very unfavorable for needing peace and quiet, vibration being had the working environment of specific (special) requirements.Therefore, the known axial-flow type radiator fan of this kind has necessity of further improvement.
Summary of the invention
Main purpose of the present utility model is to provide an a kind of housing and impeller of mainly comprising; This housing is provided with the water conservancy diversion frame, and the periphery of this water conservancy diversion frame evenly is installed with the axial-flow type radiator fan of several guide vanes that are axially and do not connect airtight.Therefore, under the constant situation of fan revolution, can increase the air output of this axial-flow type radiator fan and promote running efficiency, perhaps, under the constant situation of air quantity, can reduce the revolution of this axial-flow type radiator fan.
Secondary objective of the present utility model, being provides a kind of intake grill to include: the intake grill of housing upper end and the space between water conservancy diversion frame periphery guide vane, can reduce the axial-flow type radiator fan of the revolution of this axial-flow type radiator fan; Therefore, must reduce the noise and the vibration of this axial-flow type radiator fan, enlarge the application area of this axial-flow type radiator fan, prolong its working life.
Another purpose of the present utility model is to provide a kind of guide vane can be the axial-flow type radiator fan at certain angle of inclination with the water conservancy diversion frame, therefore, can cooperate the air intake direction, makes air intake more smooth and easy.

Embodiment
For to the purpose of this utility model, technical characteristics and advantage thereof, can have and further understand and be familiar with, lift a preferred embodiment now, and conjunction with figs. is described in detail as follows:
Please refer to shown in Fig. 2-9, be the utility model one preferred embodiment, a kind of axial-flow type radiator fan mainly comprises: a housing 10 and an impeller 20; This housing 10 is provided with into, and air port 11, upper end, lower end exhaust outlet 12, water conservancy diversion frame 13, middle position are installed with bearing 14 and electromagnetic induction stator (not shown); These water conservancy diversion frame 13 periphery rings are connected to several and are axially and do not connect airtight arrangement guide vane 132, each guide vane 132 can or be certain angle of inclination (shown in Fig. 7,8) with water conservancy diversion frame 13 mutual vertical (as shown in Figure 4), and the air intake of each guide vane 132 has the level and smooth radian (as shown in Figure 9) bigger with corresponding end limit; Four end limits of this housing 10 have fixed via 131 respectively; This impeller 20 is provided with wheel hub 21, and being installed with several fan blade 22, this wheel hub 21 and fan blade 22 on this wheel hub 21 can be one-body molded; These wheel hub 21 inner edges are installed with electromagnetic induction rotor (not shown), in the middle of this wheel hub 21 bearing 23 (as shown in Figure 6) are housed; This impeller 20 is installed in bearing 14 ends of electromagnetic induction stator by rotating shaft 23, and is positioned at water conservancy diversion frame 13.
