The utility model is described below in conjunction with the accompanying drawings and with reference to specific embodiment.
The electric machine casing 100 that Fig. 1-Fig. 3 describes the utility model embodiment is combined first.
As shown in Figure 1-Figure 3, the electric machine casing 100 of the utility model embodiment can include annular perisporium 10 and axial direction is convex
Rib 20, axial fin 20 can be arranged on the outer peripheral face of annular perisporium 10, and axially fin 20 can be along annular perisporium
10 it is axially extending, multiple axial fins 20 can be arranged at intervals along the outer peripheral face of annular perisporium 10, and multiple axial fins 20 are equal
Can be with the central axis upright of annular perisporium 10.The axial length of axial fin 20 can be at least the axial direction of annular perisporium 10
More than half of length, so as to which axial fin 20 can be remarkably reinforced the structural strength of electric machine casing 100.
In addition, as depicted in figs. 1 and 2, axial fin 20 can protrude from the outer peripheral face of annular perisporium 10, so that relative to
The electric machine casing of only annular perisporium 10, axial fin 20 add the area of the outer peripheral face of electric machine casing 100, and then motor casing
The area that body 100 is radiated by outer peripheral face is bigger, improves the heat dispersion of electric machine casing 100.
As shown in Figure 1-Figure 3, cooling duct 30 is could be formed with electric machine casing 100, cooling duct 30 both can be whole
, can also be partly in axial fin 20 in axial fin 20.Meanwhile cooling duct 30 can have first interface end
With second interface end, the first interface end of cooling duct 30 can be located at the axial direction of electric machine casing 100 respectively with second interface end
Both ends.
It is understood that the coolant such as cooling water can flow into cooling duct 30 from first interface end, and connect from second
Mouth end outflow cooling duct 30, thus the relatively low coolant of temperature can and temperature higher electric machine casing interior in cooling duct 30
100 solid section is exchanged heat, it is possible thereby to strengthen 100 further heat dispersion of electric machine casing, ensures electric machine casing
Heat caused by 100 inner members (such as the element such as rotor) work can shed in time.
According to the electric machine casing 100 of the utility model embodiment, by setting axial fin 20, electric machine casing is added
The area of dissipation of 100 outer peripheral face, while by being provided for the cooling duct 30 of heat exchange, electric machine casing 100 can have more
Strong heat dispersion, so as to which heat caused by the element manipulation inside electric machine casing 100 can dissipate from electric machine casing 100 in time
Go out.In addition, axial fin 20 can make electric machine casing 100 have stronger structural strength, electric machine casing 100 is enhanced to motor
Element inside housing 100 is protected.
In some optional embodiments of the present utility model, as shown in Fig. 2 a part of of cooling duct 30 can be located at
In axial fin 20, and another part of cooling duct 30 can be located in annular perisporium 10.Thus cooling duct 30 is in motor
It is bigger that volume is taken in housing 100, so as to improve the radiating effect of electric machine casing 100.
Further, the volume of a part for cooling duct 30 can be more than the volume of another part of cooling duct 30,
I.e. cooling duct 30, which is located at the volume in axial fin 20, can be more than the volume that cooling duct 30 is located in annular perisporium 10.By
This cooling duct 30 is predominantly located in axial fin 20, reduces reduction journey of the cooling duct 30 to the intensity of annular perisporium 10
Degree, so that annular perisporium 10 has stronger structural strength.
Further, as shown in figure 3, the electric machine casing 100 of the embodiment of the present invention can include annular perisporium 10, annular week
Wall 10 can be sandwich construction, and annular perisporium 10 can be followed successively by first annular layer 1, the second annulate lamella 2 and from inside to outside
Three annulate lamellas 3, a part of of cooling duct 30 can be formed in the 3rd annulate lamella 3.Thus electric machine casing 100 can have more
Strong overall performance.
For example, the intensity of the second annulate lamella 2 can be respectively greater than the intensity and the 3rd annulate lamella 3 of first annular layer 1
Intensity, thus, the second annulate lamella 2 positioned at intermediate layer can strengthen the overall structural strength of electric machine casing 100 as skeleton.
For example, each in the first annular layer 1 positioned at internal layer and the 3rd annulate lamella 3 positioned at outer layer can be resistance to
Corrosion layer.Thus, the inner peripheral surface of first annular layer 1 can form the inner peripheral surface of electric machine casing 100, the periphery of the 3rd annulate lamella 3
Face can form the outer peripheral face of electric machine casing 100, and thus the inner peripheral surface of electric machine casing 100 and outer peripheral face can have well
Corrosion resistance, prevent the inner and outer circumferential surfaces of electric machine casing 100 from corrosion occurs and causes intensity decreases.
In some optional embodiments, as shown in figure 3, cooling duct 30 the axial linear of fin 20 can prolong vertically
Stretch, now the bearing of trend of cooling duct 30 can be identical with the bearing of trend of axial fin 20.Thus cooling duct 30 can be with
Prolong the axial uniform heat exchange of electric machine casing 100.
It should be noted that the bearing of trend of cooling duct 30 can more than that, in other specific embodiments,
Cooling duct 30 can also extend to the axial screw of fin 20 vertically.In other words, in the axial direction of electric machine casing 100
On, cooling duct 30 can have curved section, and thus cooling duct 30 can be to axial fin 20 and annular perisporium 10
Bigger region is radiated, and enhances the heat transfer effect of cooling duct 30.
Alternatively, heat exchange convex tendon (not shown) is could be formed with the inner peripheral surface of cooling duct 30.Thus exchange heat convex
Muscle can strengthen the inner peripheral surface area in cooling duct 30, and then strengthen the heat exchange area in cooling duct 30, so as to enhance
The heat transfer effect of cooling duct 30.
Further, exchanging heat convex tendon can be along the axial linear extension of cooling duct 30.Thus cooling duct 30 can prolong
The axial uniform heat exchange of electric machine casing 100.
Further, the exchange heat both ends of convex tendon can hold level with both hands together with first interface end and second interface respectively, that is, exchange heat
The both ends that can prolong axial direction insertion heat exchanger channels of convex tendon.It is possible thereby to further enhance the overall heat exchange in cooling duct 30
Effect.
Further, the convex tendon that exchanges heat is the screw thread to be formed on the inner peripheral surface of cooling duct 30, and screw thread can be along cooling duct
30 it is circumferentially disposed.It is possible thereby to increase the inner surface heat exchange area of cooling duct 30, so as to enhance changing for cooling duct 30
Thermal effect.
