Abstract
The utility model discloses a wing type fan blade structure, which is used for being mounted in a radiator fan, and comprises a hub and a plurality of blades connected with the hub, wherein around flow structures are arranged on the blades and adopt a plurality of groove (rib) bodies arranged on the blades in an array layout, the groove (rib) bodies are gradually increased along expansion directions of blades, and arc transition is adopted between the adjacent groove (rib) bodies. By adopting the structure provided by the utility model, the wing type fan blade structure can generate around flow, and larger wind rate and lower noise are generated at the same time without needing to improve rotational speed of a motor, so as to achieve environment-friendly and energy-saving effects.
Description
Technical field
The utility model relates to a kind of blade structure, in particular a kind ofly is used for the blade structure that radiation fan is used.
Background technique
In recent years along with the development of electronic industry, the continuous lifting of the performance of electronic component, arithmetic speed is more and more faster, the arithmetic speed of its inside chip group constantly promotes, number of chips constantly increases simultaneously, the heat that is sent in the time of chip operation also increases thereupon, if untimely distributes heat, the function of electronic parts and components will greatly be influenced, the arithmetic speed of electronic parts and components is reduced, also can so that burn electronic parts and components, therefore must carry out effective radiating treatment along with the continuous accumulation of heat to electronic parts and components.
For this reason, radiation fan is installed near electronic parts and components usually, rotation by flabellum produces air-flow and directly blows to electronic parts and components or aim at radiator on the electronic parts and components, and it is effectively dispelled the heat, because the air quantity air quantity size that fan produces depends on the rotating speed with fan, for the radiating efficiency that makes fan is further improved, must increase the rotating speed of electric fan, but, rotation speed of the fan will cause fan to send bigger noise when improving, and the user is not felt well, can't stand even.Green can environmental protection with the requirement that improves quality of the life under, that the individual uses is electric, electronics except functional requirement with quality is constantly improved, environment requirement is also improved simultaneously.The minimizing in noise source is exactly one of them key project.Such as computer (table type, notebook type), microwave oven, dehumidifier, humidifier, warming and cooling fan, air-conditioning, electronic type refrigerator, air-conditioning or the like product device, the capital uses fan, also fan is wanted and can be obtained lower level of noise reaching under the same function in the requirement of using.
In view of this, be necessary to invent the flabellum that can produce big air quantity, noise was minimum when the fan of its composition can produce air flow.
The model utility content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of blade structure that produces circling gas flow to be provided, and increases air quantity when not improving motor rotary speed, reduce the blade structure of noise.
To achieve these goals, the utility model by the following technical solutions
The assistant blade structure is used to be installed in the radiation fan, and it comprises a wheel hub and blade some and that wheel hub is installed, and it is characterized in that: described blade is provided with and streams structure.
The described structure of streaming is that many strip arrays are arranged on the cell body on the blade, and this cell body increases gradually along the blade bearing of trend.
The described structure of streaming is that many strip arrays are arranged on the rib on the blade, and rib increases gradually along the blade bearing of trend.
Be the cambered surface transition between described adjacent cell body.
Be the cambered surface transition between described adjacent rib.
Assistant blade structure behind the employing said structure can produce circling gas flow, and reaches the blade structure that air flow produces when not improving motor rotary speed, can effectively reduce noise, offers convenience to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Assistant blade structure as shown in Figure 1, it comprises a wheel hub 1 and blade 2 some and that wheel hub is installed, and blade 2 is provided with many strip arrays and is arranged on cell body 3 on the blade, and cell body 3 increases gradually along blade 2 bearing of trends.3 of adjacent cell bodies is the cambered surface transition.The purpose that cell body 3 is set certainly is the result of streaming in order to produce, so cell body 3 also can substitute with the structure of similar rib.
Assistant blade structure behind the said structure can produce circling gas flow, and reaches the blade structure that air flow produces when not improving motor rotary speed, can effectively reduce noise, offers convenience to use.
The above does not just limit protection domain with this, so all trickle changes of making and equivalent variations are all in protection domain of the present utility model by the utility model in order better to illustrate under above-mentioned theory.
Claims (5)
1. the assistant blade structure is used to be installed in the radiation fan, and it comprises a wheel hub and blade some and that wheel hub is installed, and it is characterized in that: described blade is provided with and streams structure.
