Abstract
The utility model relates to an end cap for outer rotor, which comprises an end cap body (4) that includes an end cap (1) and an end cap shaft (2) integrated with the end cap (1). The end cap (1) and the end cap shaft (2) form a bearing chamber (3). The utility model is characterized in that heat radiation fins (5) are provided at the outer edge of the end cap (1). The heat radiation fins have the following advantages: reduced wall thickness of end cap, strengthened supporting rigidity of the end cap, saved aluminium material, improved pressing casting technology of the end cap; no air hole, good compactness, heat radiation function, reduced temperature raise of motor, and prolonged service life of motor.
Description
Technical field
The utility model relates to a kind of external rotor electric machine parts, is a kind of good heat dissipation specifically, compactness is good, support stiffness is strong external rotor end cap.
Background technology
Along with progress of science and technology, in HVAC, refrigeration and building service industry, people progressively adopt external rotor electric machine to replace inner rotor motor, thereby save the space, reduce energy consumption, reduce noise, and external rotor electric machine progressively at home, be used widely outward.End cap on the external rotor electric machine is its indispensable part, and the heat dispersion of external rotor end cap, support stiffness are to the function of external rotor electric machine with produce very significant effects useful life.The outside of present external rotor electric machine end cap is a plane, the external rotor ending cover thickness is just thicker like this, big with material, and on die casting usability, compactness is not fine, may have pore, the outside of plane is little with extraneous contact area simultaneously, and thermal diffusivity is poor, and motor temperature is easy to raise, the person may burn motor accidentally, thereby has influenced the useful life of motor.
As mentioned above, there is following deficiency in prior art: the external rotor ending cover thickness is just thicker, and is big with material; On the die casting usability, compactness is bad, has pore; Weak heat-dissipating, electric machine temperature rise is big.
Summary of the invention
The utility model has solved the external rotor end cap poor radiation that prior art exists, and the problem that electric machine temperature rise is big provides the external rotor end cap that a kind of thermal diffusivity is good, can reduce electric machine temperature rise;
The external rotor ending cover thickness that the utility model has also solved the prior art existence is just thicker, and is big with material; On the die casting usability, compactness is bad, can leachy problem, a kind of end cap wall thickness, external rotor end cap that compactness is good of reducing is provided.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of external rotor end cap, one end cap body is arranged, comprise end cap and the end-cover axle that is connected as a single entity with end cap, end cap and end-cover axle are formed bearing chamber, it is characterized in that described end cap outer ledge is provided with the heat radiation footpath.It is effective to dispel the heat in this heat radiation footpath, for the temperature rise that reduces motor reasonable effect is arranged, and has improved the useful life of motor; Endcap support rigidity has been strengthened in this heat radiation footpath when reducing the end cap wall thickness, saved aluminium, has improved the die casting usability of end cap; And not having pore, compactness is good.
As preferably, described heat radiation footpath slabbing, and be distributed in end cap outer ledge several regions, the heat radiation footpath in the same area evenly distributes.The several regions in the end cap outside is a uneven distribution, and how much heat radiation footpath quantity in this zone neither be duplicate, and this heat radiation footpath distribution in same zone is uniform.Because all there is a bigger surface in this sheet heat radiation footpath, therefore so many heat radiations are directly added up, and the area that contacts with air is just bigger, and the effect of the heat radiation of playing like this is also obvious.
The utility model is skillfully constructed, and the setting by the heat radiation footpath makes it have following beneficial effect compared with the prior art:
1, thermal diffusivity is good, reduces electric machine temperature rise, improves motor useful life;
2, when reducing the end cap wall thickness, strengthened endcap support rigidity, saved aluminium, reduced production costs;
3, improved the die casting usability of end cap, made it not have pore, compactness is good.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model:
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment.See Fig. 1, Fig. 2, this a kind of external rotor end cap, one end cap body 4 is arranged, comprise end cap 1 and the end-cover axle 2 that is connected as a single entity with end cap 1, these end-cover axle 2 hollows, end cap 1 is formed bearing chamber 3 with end-cover axle 2, be evenly distributed with plurality of strengthening ribs 6 in the bearing chamber 3, this reinforcement 6 can improve the intensity of end cap, and described end cap 1 outer ledge is provided with heat radiation footpath 5, the end cap wall thickness has been reduced in this heat radiation footpath 5, has also saved aluminium simultaneously.When high speed rotating, the heat radiation footpath 5 that is distributed in end cap 1 outer ledge is equivalent to a fan, can take away more heat, plays better thermolysis.
Wherein, described heat radiation footpath 5 slabbings, and be distributed in end cap 1 outer ledge several regions, the heat radiation footpath 5 in the same area evenly distributes.And heat radiation footpath 5 quantity of each the inside, zone of being divided are not exclusively the same.
It is apparent to one skilled in the art that the utility model can be changed into multiple mode, and such change is not thought and broken away from scope of the present utility model.What all were such will be included within the scope of this claim the conspicuous modification of described those skilled in the art.
Claims (2)
1. external rotor end cap, one end cap body (4) is arranged, comprise end cap (1) and the end-cover axle (2) that is connected as a single entity with end cap (1), end cap (1) is formed bearing chamber (3) with end-cover axle (2), it is characterized in that described end cap (1) outer ledge is provided with heat radiation footpath (5).
2. a kind of external rotor end cap according to claim 1 is characterized in that described heat radiation footpath (5) slabbing, and is distributed in end cap (1) outer ledge several regions that the heat radiation footpath (5) in the same area evenly distributes.
