Abstract

A centrifugal blade for cooling a micro-miniature motor comprises a hub (1) and a plurality of blades (2). The hub (1) matches with a rotating shaft of the motor, and one end of each blade (2) is connected onto the peripheral surface of the hub (1). The centrifugal blade for cooling the micro-miniature motor is characterized in that the other ends of the blades (2) are connected with an air guide ring (3), the inner side surface of the air guide ring (3) is a frustum-shaped surface, one end, with a larger opening, of the air guide ring (3) is an air inlet end, and the other end, with a smaller opening, of the air guide ring (3) is an air outlet end. The outer ends of the blades are connected integrally by the air guide ring at first, so that the blades are not easy to vibrate during operation, noise is reduced, furthermore, the inner side surface of the air guide ring is the frustum-shaped surface, one end, with the larger opening, of the air guide ring is the air inlet end, and the other end, with the smaller opening, of the air guide ring is the air outlet end, accordingly, the air guide ring can simultaneously have an air guide effect and leads air flow to enter the centrifugal blade more orderly, the speed of the air flow flowing through the air outlet end is faster, escape of the air flow can be prevented effectively, and influence of escaped air flow to the air flow is further prevented, thereby increasing efficiency and reducing power consumption.

Description

A kind of centrifugation blade that is used for the cooling of microminiature motor

Technical field

The utility model belongs to the technical field of motor, relates to a kind of centrifugation blade that is used for the cooling of microminiature motor specifically.

Background technique

Motor its temperature in the course of the work can constantly raise, and therefore needs cooling device to guarantee that its temperature can be not too high and the influence running, and the microminiature motor is like this equally.Utilizing fan blade that the microminiature motor is lowered the temperature is the means that people often adopt, and the cooling fan blade of microminiature motor mainly contains the shaft flow blade and two types of the centrifugal fans that is applied to centrifugal fan that is applied to axial fan both at home and abroad at present.

Existing centrifugal fan kind is a lot, but the low fan blade of performance high price seldom, all is independently between the blade of present centrifugal fan, shakes easily in the course of the work, produce bigger noise, on the other hand, when wind enters centrifugal fan from the outside, owing to there is not flow guide device, loss takes place in wind easily when coming in contact with blade, fan efficiency is reduced,, strengthened the power consumption of centrifugal fan on the other hand owing to the distinguished and admirable influence of these loss.Shortcomings such as therefore, existing centrifugation blade all exists efficient low, and noise is big, and power consumption is big.

Summary of the invention

The utility model provides a kind of simple in structure at deficiency of the prior art, and structural stability is reliable, and the efficient height, and noise is little, the centrifugation blade that is used for the cooling of microminiature motor low in energy consumption.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of centrifugation blade that is used for the cooling of microminiature motor, comprise and be used for the wheel hub that cooperates with machine shaft, one end is connected the some blades on the described wheel hub outer peripheral surface, the other end of described blade connects air-ducting ring, the inner side surface of this air-ducting ring is the frustoconic shape surface, and the bigger end of its opening is air intake, and the less end of opening is an outlet air end.

Air-ducting ring of the present utility model at first connects the blade outer end as a whole, make it in the middle of working procedure, be not easy to produce vibrations, reduced the generation of noise, and, because the inner side surface of air-ducting ring is the frustoconic shape surface, and the end that its opening is bigger is an air intake, the less end of opening is an outlet air end, and therefore, air-ducting ring can also play the effect of wind-guiding simultaneously, make air-flow enter in the fan blade more in an orderly manner, it is faster that air communication is crossed the speed of outlet air end, can effectively prevent the air-flow loss, further prevents the influence of loss air-flow to air-flow, raise the efficiency thereby play, reduce the effect of power consumption.

As preferably, the outer side surface of above-mentioned air-ducting ring is connected on the described blade.The above-mentioned mode of condensing can make air-flow just come in contact with blade after water conservancy diversion is finished, and has prevented the influence of blade to air-flow, makes the water conservancy diversion better effects if.

In order to obtain better technique effect, further technical measures also comprise: any one described blade is crossed a reinforced block with one of them the described blade pass that is adjacent at least and is linked to each other, and described reinforced block is near described wheel hub.Reinforced block has further been strengthened the connection between each blade, and blade is played fixation, its objective is the vibrations in the course of the work of further minimizing blade, thereby reduces noise.

As preferably, all there is reinforced block to link to each other between any two adjacent described blades, all described reinforced blockes are combined to form the stiffening ring of an annular.

The utility model compared with prior art, have following beneficial effect: air-ducting ring of the present utility model at first connects the blade outer end as a whole, make it in the middle of working procedure, be not easy to produce vibrations, reduced the generation of noise, and, because the inner side surface of air-ducting ring is the frustoconic shape surface, and the bigger end of its opening is air intake, and the less end of opening is an outlet air end, therefore, air-ducting ring can also play the effect of wind-guiding simultaneously, and air-flow is entered in the fan blade more in an orderly manner, and it is faster that air communication is crossed the speed of outlet air end, can effectively prevent the air-flow loss, further prevent of the influence of loss air-flow, raise the efficiency, reduce the effect of power consumption thereby play to air-flow.
