In addition, it should be understood that the present application is not limited to the specific embodiments presented herein. Instead, it is envisaged herein that any combination of the following features and elements can be used to implement the present application, regardless of whether or not they are involved in different embodiments. Therefore, the following aspects, features, embodiments and advantages are merely il¬ lustrative and should not be regarded as elements or definitions of the claims, unless explicitly stated in the claims.
Figs. 1 and 2 show exploded views of an electric motor in a particular embodiment according to the present application. Figs. 3-6 show sectional views of an electric motor in a particular embodiment according to the present application. Fig. 7 shows a perspective view of a cooling medium flow channel of an electric motor in a particular embodiment according to the present application. Fig. 8 shows a sectional view in a cross section D-D in Fig. 4.

It can be seen from Fig. 1 to Fig. 9 that the electric motor of the present application comprises a stator 4, a stator housing 1 encircling the stator in the circumferential direction, and a first end cover 2 and a second end cover 3 enclosing the stator 4 in the axial direction. As shown in Figs. 1-7, the stator housing 1 is provided with a straight-through cooling medium channel, a first end cover 2 and a second end cover 3 are respectively provided with through grooves 62, 63, and after the stator housing 1, the first end cover 2 and the second end cover 3 are assembled together, the straight-through cooling medium channel in the stator housing 1
n
5 and the through grooves 62, 63 in the first end cover 2 and the second end cover 3 are in mutual fluid communication so as to form a complete cooling medium flow channel 6 as shown in Fig. 7. As shown in Figs. 1-9, the stator housing 1 is provided with a straight-through cooling medium channel 61 which extends parallel to an axis of the stator 4, and the straight-through cooling medium channel 61 in the stator housing penetrates the stator housing 1 in the axial direction, so as to form a plurality of channels which run from an axial end part of the stator housing 1 all the way through to the other axial end part of the stator housing 1. A person skilled in the art could configure the number, the cross-sectional shape (e.g. an oval cross section) and the size of the straight-through cooling medium channel 61, and these variations do not depart from the scope of protection of the present application.

In particular, the through groove 63 is a semi-open groove, the cross-sectional shape of the semi-open through groove 63 is a U shape, and the semi-open through groove 63 comprises two concave parts 631 which are respectively in communication with two straight-through cooling medium channels 61 of the stator housing 1, and an internal channel 632 which is provided inside the second end cover 3 and is in communication with the two concave parts 631.

During the operation of an electric motor, a cooling medium (e.g. cooling water) flowing in the cooling medium flow channel 6 cools the electric motor so as to control the temperature of the electric motor. The cooling medium flow channel of the present application is provided not only in the stator housing 1, but also in the first
end cover 2 and the second end cover 3, so as to increase the acting area of the cooling medium and facilitate in quickly and evenly cooling the electric motor.

Alter¬ natively, the cooling medium flow channel inlet 6a and the cooling medium flow channel outlet 6b may be provided on the stator housing 1. Alternatively, one of the cooling medium flow channel
0
o inlet 6a and the cooling medium flow channel outlet 6b may be provided on an end cover, and the other may be provided on the stator housing. These variations do not depart from the scope of protection of the present application.
As shown in Figs. 1-9, the stator housing 1, the first end cover
2 and the second end cover 3 may be fastened together by a plurality of fasteners 5. The fastener 5 may be an assembly of bolts and nuts, and holes matching the fastener 5 are provided on the stator housing 1, the first end cover 2 and the second end cover 3.

Alternatively, the structure of the first end cover 2 and the second end cover 3 as shown in Figs . 1-7 may be modified slightly, such that two sets of fasteners 5 are used to fasten together the stator housing 1, the first end cover 2 and the second end cover 3 in two different directions. These variations do not depart from the scope of protection of the present application.
In the stator housing and the device for accommodating a stator provided by the present application, since the straight-through cooling medium channel in the stator housing provided by the present application is simple in structure, the extrusion technology which is mature and low in cost and defective rate can be used to manufacture a stator housing, such that the total manufacturing cost of an electric motor is reduced and the defective rate is decreased. Moreover, the cooling medium flow
channel for cooling the stator provided by the present ap¬ plication is provided not only in the stator housing, but also in the first end cover and the second end cover, so as to increase the acting area of the cooling medium and facilitate in quickly and evenly cooling the stator of the electric motor.
