Specific embodiment
The specific embodiment of the disclosure is described in detail below in conjunction with attached drawing.It should be appreciated that this place is retouched
The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
As depicted in figs. 1 and 2, the one side of the disclosure provides a kind of electric machine stand, and cooling is formed in the electric machine stand
Water channel 1, the peak of cooling water channel 1 are provided with air bleeding valve 4.Here, the peak of cooling water channel 1 refers to that motor is in installation
The peak of cooling water channel 1 during state.That is, when motor horizontal installation at a certain angle, there are one for cooling water channel 1
Peak, air bleeding valve 4 are located in the peak of cooling water channel 1.
Through the above technical solutions, since air bleeding valve 4 is arranged on the peak of cooling water channel 1, in cooling water channel 1
Coolant is below air bleeding valve 4, this bubble allowed in cooling water channel 1 can be discharged from air bleeding valve 4, consequently facilitating cooling water
Gas in road 1 is fully discharged, and then improves the cooling efficiency of engine base.
In the disclosure, cooling water channel 1 can have any suitable shape or structure.In one embodiment, such as
Shown in Fig. 1 to Fig. 3, electric machine stand is formed as circular cylinder, and the side wall of the circular cylinder is formed as double-layer structure, and same
The inner layer wall 6 and outer wall 7 that axis is set, inner layer wall 6 and outer wall 7 are spaced apart, are set between inner layer wall 6 and outer wall 7
The equally distributed multiple partitions 8 of circumferential direction along circular cylinder are equipped with, each partition 8, should along the axially extending of circular cylinder
Space between inner layer wall 6 and outer wall 7 is divided into multiple passages by multiple partitions 8, and the plurality of passage is interconnected to form S
The cooling water channel 1 of shape.
As a kind of embodiment, electric machine stand horizontal can be installed, and ensure that central axis and horizontal plane have centainly
Angle.In this case, the highs and lows of cooling water channel 1 are located at two end faces of electric machine stand respectively, and should
Highs and lows are located on the same longitudinal section of electric machine stand and in diagonal distributions.
In the disclosure, air bleeding valve 4 can be any suitable valve, can be electrically-controlled valve or hand-operated valve.
A kind of embodiment, air bleeding valve 4 can be solenoid valve, and accordingly, 1 is provided with baroceptor (not shown) in cooling water channel,
The baroceptor is higher than the water outlet 3 of cooling water channel 1, and air bleeding valve 4 is electrically connected with baroceptor.In this case, it is electric
Magnet valve gathers in cooling water channel 1 atmospheric pressure value by baroceptor, when atmospheric pressure value is more than preset value, then opens solenoid valve,
Gas in cooling water channel 1 is discharged；When atmospheric pressure value is less than the preset value, exhaust solenoid valve is closed.It is real using solenoid valve
Now automatic exhaust, it is reliable efficient.
In another embodiment, air bleeding valve 1 can be hand-operated valve, and specifically, which can select screw plug.Such as
Shown in Fig. 2, in this case, when being filled with coolant into cooling water channel 1, screw plug is opened, discharges gas.
As shown in Fig. 2, in the disclosure, electric machine stand further includes tapping valve 5.When motor horizontal installation at a certain angle
When, cooling water channel 1 is there are a minimum point, and minimum point is less than the water inlet 2 of cooling water channel 1.Tapping valve 5 is located in cooling water channel
1 minimum point.Since tapping valve 5 is located at the minimum point of cooling water channel 1, when needing to discharge or replacing coolant, drain is opened
Valve 5, drain more fully can will discharge the coolant in cooling water channel 1 as much as possible, so as to improve cooling effect
Rate.
