Abstract
The utility model relates to a kind of air-conditioner centrifugal fans, including mainboard, the shield parallel with mainboard, multiple blades being evenly distributed between mainboard and shield and multiple by adjacent blade, the channel that mainboard and shield are constituted, shield is equipped with through-hole, channel has air inlet in through hole, channel has air outlet between mainboard and shield, mainboard includes circular substrate, positioned at the wheel hub at circular substrate center and the directing plate of connection circular substrate and wheel hub, directing plate is taper and is recessed to direction blade, directing plate is equipped with multiple guide holes, multiple guide holes are located in each channel.The beneficial effects of the utility model are: forming subflow road by circular substrate, directing plate and guide hole, make turbulent flow caused by primary air along sub- flow passage, reduce the noise that irregular turbulent flow causes, and the sub-stream nozzle flowed in subflow road is along fan surface flow, so having the effect for fan for cooling.
Description
Technical field
The utility model relates to air-conditioning more particularly to a kind of air-conditioner centrifugal fans.
Background technique
General air-conditioning needs centrifugal blower to suck room air in air-conditioning, and the air in air-conditioning is discharged.From
During the work of heart blower, the primary air of air flowing is formed.But primary air can form irregular turbulent flow in air-conditioning, make sky
Vibration is generated in adjusting to make a noise.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of air-conditioning from
Heart blower can guide turbulent flow, reduce noise.
The utility model is to be achieved by the following technical programs:
A kind of air-conditioner centrifugal fan, including mainboard, the shield parallel with mainboard, it is multiple be evenly distributed on mainboard and shield it
Between blade and multiple channels being made of adjacent blade, mainboard and shield, shield be equipped with through-hole, channel has in through hole
Air inlet, channel have air outlet between mainboard and shield, and mainboard includes circular substrate, the wheel hub positioned at circular substrate center
With the directing plate of connection circular substrate and wheel hub, directing plate is taper and is recessed to direction blade that directing plate is equipped with multiple guidance
Hole, multiple guide holes are located in each channel.
According to the above technical scheme, it is preferable that air-conditioning has air inlet, gas outlet and heat exchanger, the air inlet in channel
It is connect with air inlet, the air outlet in channel is sequentially connected heat exchanger and gas outlet.
The beneficial effects of the utility model are: forming subflow road by circular substrate, directing plate and guide hole, make primary air
Caused turbulent flow reduces the noise that irregular turbulent flow causes, and the sub- gas flowed in subflow road along sub- flow passage
Stream is along fan surface flow, so having the effect for fan for cooling.
Detailed description of the invention
Fig. 1 shows the schematic view of the front view of the embodiments of the present invention.
In figure: 1. shields, 2. blades, 3. through-holes, 4. air inlets, 5. air outlets, 6. circular substrates, 7. wheel hubs, 8. guidance
Plate, 9. guide holes, 10. heat exchangers, A. primary air, B. sub-stream nozzle.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing
The utility model is described in further detail with most preferred embodiment.
As shown, a kind of air-conditioner centrifugal fan of the utility model, including mainboard, the shield 1 parallel with mainboard, Duo Gejun
The even blade 2 being distributed between mainboard and shield 1 and multiple channels being made of adjacent blade 2, mainboard and shield 1, shield 1
Equipped with through-hole 3, channel has air inlet 4 at through-hole 3, and channel has air outlet 5 between mainboard and shield 1, and mainboard includes
The directing plate 8 of circular substrate 6, the wheel hub 7 positioned at 6 center of circular substrate and connection circular substrate 6 and wheel hub 7, directing plate 8 are cone
Shape and it is recessed to 2 direction of blade, directing plate 8 is equipped with multiple guide holes 9, and multiple guide holes 9 are located in each channel.
According to above-described embodiment, it is preferable that air-conditioning has air inlet, gas outlet and heat exchanger 10, the air inlet 4 in channel
It is connect with air inlet, the air outlet 5 in channel is sequentially connected heat exchanger 10 and gas outlet.Above structure discloses a kind of centrifugation wind
The installation site of machine.
The beneficial effects of the utility model are: forming subflow road by circular substrate 6, directing plate 8 and guide hole 9, make to lead
Turbulent flow caused by air-flow reduces the noise that irregular turbulent flow causes along sub- flow passage, and flowed in subflow road
Sub-stream nozzle is along fan surface flow, so having the effect for fan for cooling.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
