The utility model is characterized in that the radiation fan is a centrifugal fan, and a fixing seat of the radiation fan is a fan center base. The periphery of a shaft base of the radiation fan is an inclined slope, and a plurality of wavy blades are arranged on the inclined slope of the shaft base. The utility model can attain the effect of increasing radiation via the wavy blades and the inclined slope-shaped shaft base, and the utility model can also attain the purpose of reducing the volume of borderline products and can be widely used for the heat radiation of various CPU and other electronic components.
Description
The utility model relates to a kind of radiation fan.
As shown in Figure 1 and Figure 2, known radiation fan mainly is that centrifugal radiation fan B is set among the closed wind-guiding cover body A, wherein closed wind scooper A includes a loam cake A1 and a base A2, and on loam cake A1, offer intake grill A11, on base A2, be provided with training wall A21, and on the appropriate location of training wall A21, offer an exhaust outlet A22.Wherein radiation fan B is centrifugal, and it mainly is that the blade B2 that plural number slightly is vertical angle is set on the periphery of radiation fan B fixed base B1.When gas is inhaled into closed wind-guiding cover body A, can form a choked flow in the bottom surface because of the gas bounce-back, and then air output is subtracted greatly, its heat sinking function also lowers greatly.In order to increase air output, the blade B2 area of radiation fan B certainly will will increase, but when increasing, the volume potential of entire heat dissipation device must increase relatively, and because of resistance increases, consumed power also improves relatively.Therefore can find, conventional construction can be because of gaseous exchange, and the phenomenon that generation is interfered mutually, and then can't be effectively with high temperature rapidly and smoothly row from, if when improving the air output of known radiation fan, the blade of radiation fan certainly will will improve its area, therefore make the related industry goods also can't effectively reduce height.
In sum, the shortcoming of known radiation fan is summarized as follows: 1, the structure of known radiation fan forms a gas rebound phenomena easily, and then produces choked flow, makes air output subtract greatly, makes radiating effect reduce relatively.If 2 will increase the air output of known radiation fan the time, the blade height of radiation fan and area certainly will be done an increase relatively, can increase its air output, therefore its overall volume will increase, for product is all towards the design direction development of mini exquisiteness now, conventional construction is a violation trend product.So known cooling fan structure will can't effectively and promptly shed high temperature it because of the choked flow phenomenon, and known radiation fan can't increase its air output on original specification basis.For this reason, the method for solution can only be to do one at the blade of radiation fan and fixed base significantly to change, and improves the heat dissipation potential of radiation fan with this, and guarantees related elements due working life can cooperate the actual demand on the present industry.
The purpose of this utility model just provides and a kind ofly can increase air output, improves the radiation fan of heat dissipation potential.
For achieving the above object, the utility model is taked following design: a kind of radiation fan, it mainly is made up of a radiation fan and a closed wind-guiding cover body, and described radiation fan contains and is located in the described closed wind-guiding cover body, its feature is at what: described radiation fan is a centrifugal fan, the fixed base of described radiation fan is fan center's seat, and the axle bed periphery of described radiation fan is an inclined slope shape, and is provided with the blade of plural shape in wave shape on the face of slope of described axle bed.
The described waveform blade of wherein said radiation fan and described fixed base can be one-body molded after, more described axle bed and described fixed base are mutually combined.
The described axle bed of wherein said radiation fan and described fixed base also can be one-body molded after, more described waveform blade is sticked on the face of slope of described axle bed in regular turn.
The utility model is owing to take above design, it has the following advantages: 1, the utility model is owing to be arranged to an inclined slope shape with axle bed, simultaneously blade is arranged to wave, therefore, can make air inflow can not form the phenomenon of gas bounce-back because of gaseous exchange is affected, the utility model will keep high air output, and the utility model is the gas flow moving-wire of a smoothness, also will make radiating efficiency of the present utility model improve relatively.2, because air output of the present utility model can continue to remain on the state of high air output, do not need as conventional construction, blades height and area to be done an increase relatively, can increase its air output, therefore, the utility model all meets towards the design direction development of mini exquisiteness fully for product now.3, because the high blast centrifugal fan in the utility model is the radiation fan that a high air quantity and high blast can be provided, therefore can be able to by the high temperature that blade and axle bed specific function structure produce electronic component rapidly row from.The utility model reaches the lifting radiating effect by its waveform blade and the axle bed that is the inclined slope shape, and make Related product be dwindled the purpose of its volume, therefore the utility model has been whipped known shortcoming fully and has been removed, and it can be widely used in the ventilation and heat of electronic components such as CPU.

As shown in Figure 3, Figure 4, the utility model mainly is radiation fan 20 to be contained be located in the closed wind-guiding cover body 10, promptly forms a radiation fan group.Wherein closed wind-guiding cover body 10 includes a loam cake 11 and a base 12, and offers intake grill 111 on loam cake 11, is provided with a training wall 121 on base 12, and offers an exhaust outlet 122 in the appropriate location of training wall 121.Wherein radiation fan 20 is a centrifugal fan, wherein the fixed base 21 of radiation fan 20 is fan center's seat, and axle bed 24 is an inclined slope shape, and the blade 22 of plural shape in wave shape is set on its face of slope, and 22 geometric spaces with the face of slope of axle bed 24 of two blades form a flow channel 23 naturally.
As Fig. 5, shown in Figure 6, the utility model mainly is to be used in the heat radiation of CPU.By the gas that the utility model sucked, will be by 22 formed flow channels 23 of two blades, because of fixed base 21 is the inclined slope shape, so the gas that is sucked can be guided 90 degree smoothly to the bottom, training wall 121 in the base 12 of closed wind-guiding cover body 10 again is with high temperature guiding exhaust outlet 122 that electronic component produced and take advantage of a situation and send the outside.
As shown in Figure 7, the utility model blade 22 can adopt integrated mode to make with fixed base 21, axle bed 24 is inserted by fixed base 21 belows to form again.
As shown in Figure 8, be another production method of the utility model, its central axis seat 24 adopts integrated mode to make with fixed base 21, blade 22 is sticked on the face of slope of axle bed 24 in regular turn again.
The utility model is the blade that the radiator shutter of centrifugal radiation fan is designed to a wave, whole fixed base is designed to an inclined slope shape, make it form a flow channel naturally, it mainly is to strengthen its air output by the complex waveform blade, and utilize its fixed base that is the inclined slope shape that the gas that sucks is descended along the gradient of fixed base, by being arranged on radiation fan training wall on every side the high temperature that electronic component produced is done a drive of taking advantage of a situation again, allow high temperature promote radiating effect by structure of the present utility model.
The mentioned content of this specification only is one of preferred embodiment of the present utility model, and its relevant application all belongs within the protection domain of the present utility model.
