Abstract
The utility model provides a motor fan cover belongs to the motor field. The low problem of radiating efficiency when it has solved current motor fan cover cooperation motor. This motor fan cover, including fan housing, fan housing includes a cylindrical cover section of thick bamboo and connects the rear end cap in a cover one end, is equipped with a plurality of air intakes on the rear end cap, rear end cap orientation cover section of thick bamboo one side is equipped with a plurality of wind -guiding bulge loops, and the wind -guiding bulge loop has the wind -guiding hole that communicates with air intake one end, the skew rear end cap center in wind -guiding hole to the setting of erroneous tendency cover section of thick bamboo wall, one side that a cover section of thick bamboo was kept away from to the rear end cap is connected with the metal mesh, and still is equipped with the filter pulp of crossing that covers the air intake between metal mesh and the rear end cap. Because the skew rear end cap center in wind -guiding hole to the setting of erroneous tendency cover section of thick bamboo wall, thus the wind -guiding hole can guide air inlet wind and surround blow to the stator on, it can very big improvement radiating efficiency to make, because the wind -guiding bulge loop is established in rear end cap orientation cover section of thick bamboo one side, so manufacturing cost reduces, sets up the filter pulp in addition and has the effect of filtering the dust simultaneously.
Description
Technical field
The utility model belongs to technical field of motors, relates to a kind of motor fan housing.
Background technology
Existing motor fan housing generally just end face with the case of ventilation hole, for be located at motor afterbody blower fan outside, prevent the flabellum of blower fan from being caused injury to personnel by false touch.But in fact, if the cooling air be blown into by blower fan by the ventilation hole on motor fan housing is without rectification, the wind flow path that blows on stator can be caused inconsistent, lose larger, accept air quantity everywhere uneven, will radiating effect be reduced.
Utility model content
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of motor fan housing that can improve radiating efficiency.
The purpose of this utility model realizes by following technical proposal: a kind of motor fan housing, comprise fan housing shell, fan housing shell comprises tubular cover cylinder and is connected to the rear end cap of cover cylinder one end, described rear end cap is provided with some air inlets, it is characterized in that: described rear end cap is provided with some wind-guiding bulge loops towards cover cylinder side, and wind-guiding bulge loop has the air-guiding hole be communicated with air inlet one end, described air-guiding hole departs from rear end cap center, and be partial to the setting of cover cylinder barrel, described rear end cap is connected with wire netting away from the side of cover cylinder, and between described wire netting and rear end cap, be also provided with the filter cotton covering air inlet.
Because air-guiding hole departs from rear end cap center, and be partial to the setting of cover cylinder barrel, therefore air-guiding hole can guide air inlet air intake and around blowing on stator, make to improve radiating efficiency greatly, simultaneously because wind-guiding bulge loop is located at rear end cap towards cover cylinder side, therefore production cost reduces, and arranges the effect that filter cotton has filter dust.
In above-mentioned a kind of motor fan housing, between described filter cotton and rear end cap, be also provided with acoustical cotton, and acoustical cotton is provided with some sound-absorbing projections be embedded in air inlet.
Therefore the noise produced owing to arranging wind-guiding bulge loop can also be reduced.
In above-mentioned a kind of motor fan housing, described cover cylinder and rear end cap are structure as a whole, and wind-guiding bulge loop is rear end cap punching press formation.
In above-mentioned a kind of motor fan housing, after described air inlet, centered by end cap central position, end cap circumference disperses distribution backward.
Compared with prior art, the utility model tool has the following advantages:
Because air-guiding hole departs from rear end cap center, and be partial to the setting of cover cylinder barrel, therefore air-guiding hole can guide air inlet air intake and around blowing on stator, make to improve radiating efficiency greatly, simultaneously because wind-guiding bulge loop is located at rear end cap towards cover cylinder side, therefore production cost reduces, and arranges the effect that filter cotton has filter dust.
Accompanying drawing explanation
Fig. 1 is this fan housing structure of motor schematic diagram.
In figure,

2, rear end cap; 21, air inlet; 22, wind-guiding bulge loop; 23, air-guiding hole;
3, wire netting;
4, filter cotton;
5, acoustical cotton; 51, sound-absorbing is protruding.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, a kind of motor fan housing of the utility model, comprise fan housing shell, fan housing shell comprises tubular cover cylinder 1 and is connected to the rear end cap 2 of cover cylinder 1 one end, rear end cap 2 is provided with some air inlets 21, rear end cap 2 is provided with some wind-guiding bulge loops 22 towards cover cylinder 1 side, and wind-guiding bulge loop 22 has the air-guiding hole 23 be communicated with air inlet 21 one end, air-guiding hole 23 departs from rear end cap 2 center, and be partial to the setting of cover cylinder 1 barrel, rear end cap 2 is connected with wire netting 3 away from the side of cover cylinder 1, and is also provided with the filter cotton 4 covering air inlet 21 between wire netting 3 and rear end cap 2.
Further, between filter cotton 4 and rear end cap 2, be also provided with acoustical cotton 5, and acoustical cotton 5 is provided with some sound-absorbing projections 51 be embedded in air inlet 21.Cover cylinder 1 and rear end cap 2 are structure as a whole, and wind-guiding bulge loop 22 is rear end cap 2 punching press formation.Air inlet 21 centered by rear end cap 2 center backward end cap 2 circumference disperse distribution.
Because air-guiding hole 23 departs from rear end cap 2 center, and be partial to the setting of cover cylinder 1 barrel, therefore air-guiding hole 23 can guide air inlet 21 air intake and around blowing on stator, make to improve radiating efficiency greatly, simultaneously because wind-guiding bulge loop 22 is located at rear end cap 2 towards cover cylinder 1 side, therefore production cost reduces, and arranges the effect that filter cotton 4 has filter dust.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the terms such as cover cylinder 1, rear end cap 2, air inlet 21, wind-guiding bulge loop 22, air-guiding hole 23, wire netting 3, filter cotton 4, acoustical cotton 5, sound-absorbing projection 51 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
