The foregoing is to be understood as belonging to the specific meanings in the present application as appropriate to the person of ordinary skill in the art.
The present application discloses a cooling flow channel in an embodiment, as shown in fig. 1, which includes a controller flow channel 10, a motor flow channel 20, a channel 30 communicating the controller flow channel 10 and the motor flow channel 20, and a valve 4 disposed in the channel 30 and configured to control opening and closing of the channel 30.
When the valve 4 is in the open state, the controller flow path 10 communicates with the motor flow path 20.
When the valve 4 is in the closed state, the controller flow path 10 is disconnected from the motor flow path 20.
As shown in fig. 1, when the cooling flow channel is in a normal use state, the valve 4 is kept in an open state, and the cooling liquid in the controller flow channel 10 can flow to the motor flow channel 20 through the channel 30, so that cooling is achieved. As shown in fig. 2, when the cooling flow channel is not in use, the valve 4 is closed to disconnect the controller flow channel 10 and the motor flow channel 20, so that the cooling liquid does not flow to the motor flow channel 20 when residing in the controller flow channel 10, and then the controller flow channel 10 and the motor flow channel 20 are detached and separated, thereby effectively avoiding potential safety hazards caused by the electronic components around the motor that the cooling liquid flows outside and falls, avoiding waste caused by the cooling liquid, and improving the efficiency of detaching and separating the control flow channel and the motor flow channel 20.
In one embodiment of the present application, the valve 4 is an elastic valve 40 that can be automatically opened and closed according to a change in a pressure difference between the coolant in the controller flow passage 10 and the coolant in the motor flow passage.
When the pressure applied to the elastic valve 40 by the cooling liquid in the controller flow channel 10 is greater than the sum of the elastic force of the elastic valve 40 itself and the pressure of the cooling liquid in the motor flow channel 20 in a normal use state of the cooling flow channel, the elastic valve 40 is opened under the action of the pressure difference, and the cooling liquid flows from the controller flow channel 10 to the motor flow channel 20 to realize cooling. When the cooling flow channel is in a non-use state, the flow rate and the pressure of the cooling liquid in the controller flow channel 10 are reduced, the pressure of the cooling liquid in the controller flow channel 10 is smaller than the sum of the elastic force of the elastic valve 40 and the pressure of the cooling liquid in the motor flow channel 20, the elastic valve 40 is closed under the action of the elastic force of the elastic valve 40, and the controller flow channel 10 is disconnected from the motor flow channel 20, so that the cooling liquid does not flow to the motor flow channel 20 when staying in the controller flow channel 10.
In one embodiment of the present application, as shown in fig. 4, a support 301 is disposed in the channel 30, and the support 301 is provided with a communication hole 3012 and a mounting hole 3011.
The elastic valve 40 includes a valve stem 401 fixedly installed in the installation hole 3011 and an elastic valve sheet 402 attached to the valve stem 401.
The elastic valve plate 402 is arranged on one side of the bracket 301 close to the motor flow passage 20.
The elastic sheet 402 blocks the communicating hole 3012 and the communicating hole 3012.
In a normal use state of the cooling flow channel, when the pressure applied to the resilient valve sheet 402 by the cooling liquid in the controller flow channel 10 is greater than the sum of the self-elasticity of the resilient valve sheet 402 and the pressure of the cooling liquid in the motor flow channel 20, the resilient valve sheet 402 deforms and deforms downward, so that the resilient valve sheet is separated from the communication hole 3012 and the cooling liquid in the controller flow channel 10 can flow to the motor flow channel 20 through the communication hole 3012.
When the cooling flow channel is not in use, the flow rate and the pressure of the cooling liquid in the controller flow channel 10 are reduced, the pressure applied to the elastic valve plate 402 by the cooling liquid in the controller flow channel 10 is smaller than the sum of the elastic force of the elastic valve plate 402 and the pressure of the cooling liquid in the motor flow channel 20, and the elastic valve plate 402 is deformed and reset upwards under the action of the elastic force of the elastic valve plate 402 and covers the communication hole 3012 to disconnect the controller flow channel 10 from the motor flow channel 20.
The support 301 is fixedly connected with the flow channel, when the cooling flow channel is in a normal use state, the elastic valve plate 402 can deform under the action of pressure difference and deform downwards, so as to be separated from the communication hole 3012, at the moment, the cooling liquid in the controller flow channel 10 can flow to the motor flow channel 20 through the communication hole 3012, when the cooling flow channel is in a non-working state, the flow rate of the cooling liquid in the controller flow channel 10 is reduced, the pressure is reduced, the elastic valve plate 402 deforms upwards under the action of self elasticity to reset and covers the communication hole 3012, so that the controller flow channel 10 is disconnected from the motor flow channel 20, and the cooling liquid stays in the controller flow channel 10 and cannot flow to the motor flow channel 20.
Specifically, a plurality of communicating holes 3012 are disposed on the support 301, the communicating holes 3012 may be arc-shaped holes, circular holes, or special-shaped holes, and the communicating holes 3012 are disposed in a covering plane of the resilient valve sheet 402, so as to ensure that the resilient valve sheet 402 can completely cover the communicating holes 3012 to prevent leakage when the cooling flow channel is in a non-working state.
The surface of the end part of the elastic valve plate 402 far away from the valve rod 401 is a polished surface, so that the surface can be covered and attached on the surface of the bracket 301 to improve the sealing performance.
In one embodiment of the present application, when the elastic valve 40 is in an open state, the elastic valve sheet 402 is bent toward the motor flow channel 20 by the pressure difference, so that the coolant in the controller flow channel 10 can flow to the motor flow channel 20 through the communication hole 3012.
When the elastic valve 40 is in a closed state, the flow rate of the coolant in the controller flow channel 10 is reduced, the pressure is reduced, and the elastic valve sheet 402 is deformed upward by its own elastic force to be reset and covers the communication hole 3012 so that the controller flow channel 10 is disconnected from the motor flow channel 20.
When the cooling flow channel is in a normal use state, the pressure applied to the elastic valve plate 402 by the cooling liquid in the controller flow channel 10 is greater than the sum of the elastic force of the elastic valve plate 402 and the pressure of the cooling liquid in the motor flow channel 20, the elastic valve plate 402 is bent towards one side of the motor flow channel 20 under the action of pressure difference, at this time, the elastic valve plate 402 is separated from the surface of the bracket 301 and is separated from the communication hole 3012 arranged on the bracket 301, at this time, the controller flow channel 10 and the motor flow channel 20 are in a communication state, and the cooling liquid can flow from the controller flow channel 10 to the motor flow channel 20. Further, as the pressure difference increases, the degree of bending of the elastic valve sheet 402 increases, so that the resistance of the elastic valve sheet 402 against the coolant passing through the communication hole 3012 decreases, and the flow rate of the coolant increases. When the cooling flow channel is in a non-working state, the flow rate and the pressure of the cooling liquid in the controller flow channel 10 are reduced, the pressure applied to the elastic valve plate 402 by the cooling liquid in the controller flow channel 10 is smaller than the sum of the elastic force of the elastic valve plate 402 and the pressure of the cooling liquid in the motor flow channel 20, the elastic valve plate 402 deforms upwards under the action of the elastic force and resets and is attached to the surface of the bracket 301, and the elastic valve plate 402 covers the communication hole 3012 so that the cooling liquid stays in the controller flow channel 10 and cannot flow to the motor flow channel 20.

In one embodiment of the present application, the elastic valve 40 further includes a limit protrusion 403 for limiting the valve stem 401 from being detached from the mounting hole 3011, the limit protrusion 403 being disposed on the valve stem 401.
The limiting lug 403 and the elastic valve plate 402 are arranged on two opposite sides of the mounting hole 3011. When the cooling liquid passes through the channel 30, the elastic valve plate 402 is impacted by the cooling liquid to drive the valve rod 401 to have an acting force moving towards the motor flow channel 20, so that the valve rod 401 cannot be separated from the mounting hole 3011 under the limiting action of the limiting bump 403.
In one embodiment of the present application, the diameter of the limit projection 403 increases from the controller flow passage 10 to the motor flow passage 20. When the valve rod 401 is installed in the installation hole 3011, the limiting projection 403 is inserted into the installation hole 3011 from one side of the motor flow channel 20 to the controller flow channel 10, so that the limiting projection 403 can pass through the installation hole 3011 from one side of the bracket 301 close to the motor flow channel 20 to one side of the bracket 301 close to the controller flow channel 10, and the limiting projection 403 contacts with the end face of the bracket 301 close to one side of the controller flow channel 10, so that the valve rod 401 cannot be separated from the installation hole 3011.
