Abstract
The utility model relates to the technical field of three-phase asynchronous motors, in particular to a three-phase asynchronous motor heat dissipation fan blade. The heat dissipation fan blade includes a fan bald body. A plurality of blades are uniformly arranged in the circumferential direction of the fan blade body; a side edge of each blade forms an included angle with a vertical line, wherein the included angle is in a range of 180 degrees to 250 degrees. When the three-phase asynchronous motor heat dissipation fan blade of the utility model is used, air flow swirling outwards is produced inside a motor through rotating the blades with inclined angles, such that heat inside the motor can be dissipate outwards, thereby greatly reducing the temperature inside the motor as well as ensuring the stability of the operation of the motor and prolonging the service life of the motor at the same time. The three-phase asynchronous motor heat dissipation fan blade of the utility model has the advantages of simple structure, reasonable arrangement, low manufacture cost and the like.
Description
Technical field
The utility model relates to the threephase asynchronous technical field, particularly a kind of threephase asynchronous cooling wind blade.
Background technology
Along with the fast development of electric automatization, threephase asynchronous also obtains using more and more widely.Some motor can be installed in the narrow and small seal cavity usually, flows because the air of seal cavity is difficult,
Motor by long-time running after just easily heating, and can cause various faults.Therefore, how the radiating effect of lifting motor guarantees that the problems such as stability of motor operation have become the in the industry focus of research.
As shown in Figure 1, blade 2 sides of existing threephase asynchronous blade 1 are parallel with vertical line, can not fully the dissipation of heat of motor interior be gone out like this, often therefore cause motor to burn, and bring larger economic loss to the user.
Therefore be necessary existing blade structure is carried out further technological innovation.
The utility model content
The purpose of this utility model is for the defective of prior art and deficiency, and threephase asynchronous cooling wind blade a kind of simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of threephase asynchronous cooling wind blade described in the utility model comprises blade, evenly is provided with several blades on the circumferencial direction of described blade, and the side of described blade and vertical line are an angle, and the described angle number of degrees are 18
0~25
0
Further, the described angle number of degrees are 21
0
Further, the quantity of described blade is eight.
Further, described blade adopts plastic material to make.
After adopting said structure, the utility model beneficial effect is: a kind of threephase asynchronous cooling wind blade described in the utility model, comprise blade, evenly be provided with several blades on the circumferencial direction of described blade, the side of described blade and vertical line are an angle, and the described angle number of degrees are 18
0~25
0When using the utility model, by the blade of rotation with angle, make motor interior form the air-flow of one outward turn, thereby the dissipation of heat of motor interior is gone out, greatly reduced the temperature of motor interior, can guarantee simultaneously the stability of motor operation, prolong the useful life of motor.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model;
Description of reference numerals:
1, blade; 2, blade; α, angle.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 2, a kind of threephase asynchronous cooling wind blade described in the utility model comprises blade 1, evenly is provided with several blades 2 on the circumferencial direction of described blade 1, and blade 2 quantity of the present utility model are preferably eight.
The side of described blade 2 and vertical line are an angle α, and the described angle α number of degrees are 18
0~25
0, the angle α number of degrees of the present utility model are preferably 21
0, the blade 2 that so just is conducive to rotate produces outer rotational gas flow, thereby the dissipation of heat of motor interior is gone out, and plays the effect that reduces the motor interior temperature.
In order to reduce the cost of manufacture of motor, blade 1 of the present utility model is preferably made with plastic material.
When using the utility model, not only the dissipation of heat of motor interior can be gone out, reduce the temperature of motor interior, and can guarantee the stability of motor operation, prolong the useful life of motor.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above only is better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
