Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection range of the present utility model with this.
As Fig. 1, shown in Figure 4, motor comprises support shell 1, be positioned at the end cap 2 of support shell one end, be positioned at fan housing cylinder 5 and the fan housing window 6 of the support shell other end.All be provided with many radiating ribs 11,21 on support shell 1, end cap 2 outer surfaces; Every radiating ribs 11 and rotating shaft 3 runs parallel of support shell 1 outer surface; The radiating ribs 21 of end cap 2 outer surfaces centered by rotating shaft 3 outwards radially, every radiating ribs 21 and rotating shaft capwise.
in conjunction with shown in Figure 2, substantially be positioned at the centre position of support shell 1 inside because of electric machine iron core, and core center place temperature is the highest, far away apart from core center, its temperature is lower, its variations in temperature is parabolic shape substantially, therefore, every radiating ribs 11 outers 111 formation arcs in the utility model on support shell 1, the height of 112 height design in the middle of radiating ribs 11, radiating ribs 11 both sides 113 during more close to support shell 1 two ends are highly lower, increased like this area of dissipation of iron core mid portion, fusiform fin of while, can better reduce electric machine temperature rise, reduce motor copper loss and aluminium consumption, improve electric efficiency, improve simultaneously motor winding insulation part useful life.
In conjunction with shown in Figure 3, the main thermal source of end cap 2 is bearings 4 of supporting revolving shaft 3, that is to say, higher the closer to rotating shaft 3 place's temperature, therefore 21 outers 211 of every radiating ribs on end cap 2 form arc, the height of the height design of one end 212 of every radiating ribs 21 close rotating shafts 3, radiating ribs 21 is more highly lower to the other end 213.Be conducive to like this reduce bearing 4 temperature, extend 4 useful lifes of bearing.
As Fig. 5, shown in Figure 6, comprise numerous fresh air inlet 7 on fan housing window 6, fresh air inlet 7 spread geometries are cyclone type, and a centre slice 8 is established at fan housing window 6 centers, take centre slice 8 as the center of circle, many circular concentric ribs 61 are connected each circular rib 61 with Duo Gen dowel 62 is set.Dowel 62, and is arranged along even circumferential to external radiation by centre slice 8.The larger dowel of several diameters can be set as main dowel 620 in many dowels 62.
Better scheme is by circular rib 61, fan housing window 6 to be divided into a plurality of regional 9,10, dowel 62 radiation from inside to outside in each zone, and arrange along even circumferential, and it is increasing from inside to outside to cut apart the area of the fresh air inlet 7 that forms by circular rib 61, dowel 62 in each zone.
Better scheme is that dowel 62 is unidirectional arc, makes the four edges of each fresh air inlet 7 that is made of circular rib 61, arc dowel 62 be arc, and the fresh air inlet 7 that a plurality of arc-shaped sides consist of is arranged and formed the cyclone type shape.Fan housing window 6 air-out areas promote 8-25% than criss-cross of the prior art, can reach better cooling effect.Single fresh air inlet Area Ratio criss-cross of the prior art increases to some extent, can reduce the viscosity property of air intake, improves intake velocity.
The end of fan housing cylinder 5 arranges large chamfering 51 structures, is conducive to reduce the eddy current loss between fan and fan housing, improves fan efficiency.
Traditional fan housing side surrounds is shaped as cylindrical shape, and after fan housing was assembled to the casing end, the radiating ribs 11 on the support shell 1 that protrudes along the fan housing sidewall was highly different, is unfavorable for heat radiation.The utility model is designed to octagonal tubular structure with fan housing cylinder 5 shapes that the fan housing side surrounds, the side of octagon fan housing cylinder 5 is eight faces, two off-centre operation cambered surface areas on upper and lower two off-centre operation cambered surfaces and both sides are larger, match with the shape of radiating ribs 11 on casing 1, make the radiating ribs 12 of protruding along fan housing cylinder 5 sidewalls highly close or identical, the whirlwind that the fan rotation is produced transfers to from fan housing window 6 radiating ribs that radial distributes, and can improve its heat-sinking capability.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection range of the present utility model.
