[0034] The technical solutions of the embodiments of the application are described in detail below with reference to the drawings.

[0035] Figure 1 is a structural schematic diagram of the cooling liquid container shown in the embodiments of the application.

[0036] Referring to Figure 1The application provides a cooling liquid container, which comprises a container body and a flow guide exhaust structure 200, a liquid storage space is formed in the container body, the container body is provided with a liquid inlet 110 which is in communication with the liquid storage space; the flow guide exhaust structure 200 is arranged in the container body, the flow guide exhaust structure 200 comprises a liquid inlet end 211 and a liquid outlet end 221, the liquid inlet end 211 is in communication with the liquid inlet 110, and the liquid outlet end 221 is located at a predetermined position in the liquid storage space; the flow guide exhaust structure 200 is used for guiding the cooling liquid introduced by the liquid inlet 110 to the liquid outlet end 221, so that the cooling liquid discharged from the liquid outlet end 221 is gas-liquid separated.

[0037] According to the scheme provided in the application, the flow guide exhaust structure 200 is arranged in the liquid storage space in the container body, the flow guide exhaust structure 200 can guide the cooling liquid introduced by the liquid inlet 110 to the liquid outlet end 221, so that the cooling liquid discharged from the liquid outlet end 221 is gas-liquid separated, and then the cooling liquid discharged from the liquid outlet 130 of the cooling liquid container does not contain bubbles, the influence of the cooling effect of the cooling system is avoided, and the problems of cavitation and dry running wear of the cooling liquid pump are also avoided.

[0038] In the application, the cooling liquid container is also referred to as a cooling liquid kettle or a cooling liquid water kettle. The cooling liquid container is a component structure in a vehicle cooling system, which is used for filling and storing cooling liquid and providing the cooling liquid to the cooling system through the liquid outlet when needed.

[0039] In the application, the liquid outlet end 221 of the flow guide exhaust structure 200 has a first distance from the bottom wall 103 of the container body, and the liquid inlet end 211 of the flow guide exhaust structure 200 has a second distance from the bottom wall 103 of the container body; the first distance is greater than the second distance, so that the liquid outlet end 221 of the flow guide exhaust structure 200 is higher than the position of the liquid inlet 110 of the cooling liquid container in the liquid storage space, the liquid level of the cooling liquid flowing back into the container body from the liquid inlet 110 is raised by the flow guide exhaust structure 200, the bubbles in the cooling liquid also rise in the process of rising of the liquid level, and the cooling liquid is separated from the bubbles at the top of the liquid storage space.

[0040] In the application, the container body and the flow guide exhaust structure 200 are an integrally formed structure, so that the structural stability of the flow guide exhaust structure 200 in the container body is improved, the flow guide exhaust structure 200 not only can realize gas-liquid separation, but also has the effect of structural reinforcement on the liquid storage container 100.

[0041] In some embodiments, the liquid inlet 110 is arranged on the side wall 102 of the container body, the lower part of the container body is provided with a liquid outlet 130, and the top part is provided with a filling port 120; the liquid inlet 110 and the liquid outlet 130 are respectively located on the two sides of the vertical center line of the container body, the filling port 120 is arranged along the vertical center line, and the liquid inlet 110 is located on the lower side of the transverse center line of the container body.

[0042] Continuing to refer toFigure 1 The flow guide exhaust structure 200 comprises the first sub-flow channel 210 and the second sub-flow channel 220 which are connected in communication, the liquid inlet end 211 is arranged at the first sub-flow channel 210, and the liquid outlet end 221 is arranged at the second sub-flow channel 220; the first sub-flow channel 210 extends in the transverse direction, and the second sub-flow channel 220 extends in the longitudinal direction.

[0043] In the present application, the first sub-flow channel 210 and the second sub-flow channel 220 can be formed by a pipeline assembly fixedly arranged in the container body, and the pipeline assembly of the first sub-flow channel 210 and the second sub-flow channel 220 divides the liquid storage space in the container body into a first region A, a second region B and a third region C, wherein the region corresponding to the upper side of the liquid level line L of the liquid outlet end 221 of the flow guide exhaust structure 200 is a fourth region, the first region A, the second region B and the third region C are located below the fourth region, the first region A and the third region C are located on the left side of the second sub-flow channel 220 and are respectively located on the upper and lower sides of the first sub-flow channel 210, and the third region C is located on the right side of the second sub-flow channel 220. In the present application, the liquid outlet 130 of the liquid storage container 100 is arranged at the bottom wall 103 of the container body corresponding to the third region C.

[0044] In the related art, the liquid returned to the liquid storage container 100 from the liquid inlet 110 has gas, since the liquid inlet 110 of the liquid storage container 100 is close to the bottom of the liquid storage container 100, and the liquid storage container 100 is hollow, the cooling liquid introduced from the liquid inlet 110 will quickly flow to the liquid outlet 130, so that this part of gas cannot be separated from the cooling liquid in time and directly continues to enter the cooling system from the liquid outlet 130 for circulation. Since there is gas in the cooling liquid, the performance of the cooling system and the service life of the parts of the cooling system will be affected.

[0045] The scheme of the present application, since the flow guide exhaust structure 200 is arranged, the cooling liquid introduced from the liquid inlet 110 will not directly flow to the liquid outlet 130, but first flow horizontally along the first sub-flow channel 210, and then vertically upwardly flow through the second sub-flow channel 220, and only when the liquid level in the flow guide exhaust structure 200 overflows the liquid outlet end 221 of the flow guide exhaust structure 200, the cooling liquid will flow downwardly to the liquid outlet 130 at the bottom of the liquid storage container 100. Therefore, after the water level is gradually lifted to the liquid outlet end 221 in the second sub-flow channel 220, the cooling liquid flows downwardly due to the action of gravity, and the gas D keeps flowing upwardly in the original direction, so that gas-liquid separation is realized.

[0046] Continuing to refer to Figure 1In the present application, the opening of the liquid outlet end 221 of the flow guide exhaust structure 200 is arranged towards the top wall 101 of the container body, and there is a preset distance between the liquid outlet end 221 and the top wall 101. The area between the liquid outlet end 221 and the top wall 101 is the fourth area. The gas D rises to the top of the liquid storage container 100 due to the buoyancy, and a gas layer is formed in the fourth area, thereby realizing gas-liquid separation. Further, the cooling liquid flowing to the liquid outlet 130 does not carry gas, and since the cooling system does not have gas entering, the performance of the cooling system and the service life of the parts of the cooling system are not affected.

[0047] In the related art, the cooling liquid filled from the filling port 120 of the liquid storage container 100 directly flows downward to the liquid outlet 130, so that the gas in the cooling liquid cannot be separated from the cooling liquid in time and directly continues to enter the cooling system for circulation from the liquid outlet 130.

[0048] In the present application, the liquid outlet end 221 of the flow guide exhaust structure 200 is opposite to the filling port 120 in the vertical direction, and the caliber of the liquid outlet end 221 is greater than or equal to the caliber of the filling port 120. The caliber can be the inner diameter of the opening of the liquid outlet end 221 and the filling port 120. After being arranged in this way, the cooling liquid filled from the filling port 120 first enters the flow guide exhaust structure 200 from the liquid outlet end 221, that is, the cooling liquid introduced from the filling port 120 does not directly flow to the liquid outlet 130, but first enters the flow guide exhaust structure 200. When the liquid level in the flow guide exhaust structure 200 overflows the liquid outlet end 221 of the flow guide exhaust structure 200, it flows downward to the liquid outlet 130 at the bottom of the liquid storage container 100. Therefore, after the water level gradually rises to the liquid outlet end 221 in the second sub-flow channel 220, the cooling liquid flows downward due to the action of gravity, and the gas flows upward in the original direction, thereby realizing gas-liquid separation.

[0049] In some embodiments, the pipe diameter of the second sub-flow channel 220 is greater than the pipe diameter of the first sub-flow channel 210. After being arranged in this way, after the cooling liquid sub-liquid inlet end 211 enters the flow guide exhaust structure 200, it can quickly flow to the second sub-flow channel 220. Since the pipe diameter of the second sub-flow channel 220 is larger, the volume is also larger, and the liquid level of the cooling liquid slowly rises in the second sub-flow channel 220, which can make the gas separate faster in a short time.

[0050] Continuing to refer to Figure 1 In some embodiments, the second sub-flow channel 220 is arranged along the vertical center line of the container body, and the bottom end of the second sub-flow channel 220 is connected with the bottom wall 103 of the container body. The bottom wall 103 is used to block the bottom end of the second sub-flow channel 220. After being arranged in this way, the center of gravity of the liquid storage container 100 will not be offset, and the bottom wall 103 of the container body can support the flow guide exhaust structure 200, thereby ensuring the structural stability of the flow guide exhaust structure 200 and the liquid storage container 100.

[0051] Correspondingly, the application provides a cooling system, comprising the cooling liquid container and the cooling liquid pipeline assembly of the above embodiments, the outlet 130 of the cooling liquid container is communicated with the cooling liquid pipeline assembly, the cooling liquid pipeline assembly and the inlet and outlet of the cooling liquid container can form a cooling liquid circulation loop, and the backflow cooling liquid is guided out of the cooling liquid container from the inlet of the cooling liquid container.

[0052] The cooling system provided by the application can avoid the cavitation and dry running wear problems of the cooling liquid pump.

[0053] The application also provides a vehicle, which is provided with the cooling system of the above embodiments. The vehicle can be a new energy vehicle driven by electricity. Since the vehicle comprises the cooling system, the cooling system can maintain the optimal working temperature of the battery, motor, electronic control and other devices of the vehicle, thereby improving the performance of the vehicle.
