Detailed Description

Embodiments of the present application may provide a vehicle, such as an automobile, motorcycle, airplane, truck, boat, train engine, etc., that may be any vehicle that at least partially uses electrical energy stored on the vehicle to power a traction motor, illustratively a plug-in vehicle having a battery pack that may be charged by an external plug or using regenerated electrical power from the motor.

Fig. 1 is a schematic diagram of a vehicle according to an embodiment of the present application. Referring to fig. 1, the vehicle may include a thermal management system 300 and a device to be tempered, the thermal management system 300 being coupled to the device to be tempered for tempering the temperature of the device to be tempered. The temperature device to be conditioned may include basic components of a powertrain 700, a battery pack 400, electronics 500, a passenger compartment 600, etc., wherein the battery pack 400 is used to provide power to the electronics 500, the powertrain 700 may include, for example, a traction motor and a gearbox, and the electronics 500 may be used to drive the motor and gearbox to propel a vehicle. The passenger compartment 600 is the area inside the vehicle that is used for the user to drive or ride.

The thermal management system 300 is used to control the temperature of the powertrain 700, the battery pack 400, the electronics 500, the passenger compartment 600, and other components. Fig. 2 is a simplified schematic diagram of a thermal management system according to an embodiment of the present application, and referring to fig. 2, a thermal management system 300 may include a compressor 31, a condenser 32, an evaporator 33, a water pump 34, a multi-channel valve 100, and the like, wherein the compressor 31, the condenser 32, and the evaporator 33 may be sequentially connected through pipes to form a refrigerant loop, and the condenser 32 and the evaporator 33 may be respectively connected to the multi-channel valve 100 to form a cooling liquid loop.

It should be noted that, not shown in the drawing, a plurality of external ports may be disposed in the refrigerant loop, a plurality of external ports may be disposed in the cooling liquid loop, and the multi-channel valve 100 itself has a plurality of liquid inlet ports and liquid outlet ports, where these ports may connect the components of the power assembly 700, the battery pack 400, the electronic device 500, the passenger cabin 600, and the like into the thermal management system 300, so that the thermal management system 300 may heat or cool these components.

The working principle of the refrigerant loop can be considered that the gaseous refrigerant enters the compressor 31, is compressed by the compressor 31 and is converted into the high-temperature and high-pressure refrigerant, the high-temperature and high-pressure refrigerant exchanges heat at the condenser 32 to become the medium-temperature and medium-pressure refrigerant, and then the refrigerant passes through the evaporator 33 to exchange heat and becomes the gaseous refrigerant to return to the compressor 31. Thus, the coolant in the coolant loop may absorb heat at the condenser 32 to heat the components of the battery pack 400, etc. connected in the loop, and the coolant in the coolant loop may dissipate heat at the evaporator 33 to cool the components of the powertrain 700, etc. connected in the loop.

The condenser 32 and the evaporator 33 connected in the refrigerant loop are a water-cooled condenser and a water-cooled evaporator, and it should be understood that the cooling liquid loop can also be connected with devices such as an air-cooled condenser, an air-cooled evaporator, a radiator module, a heater and the like through a multi-way valve, so that the heat management system realizes more diversified refrigeration and heating modes.

It should be appreciated that the powertrain 700, the battery pack 400, the electronic device 500, the passenger compartment 600, etc. all have different heating or heat dissipation requirements, and need to be selectively connected to the evaporator 33, the condenser 32, and other cooling and heating components according to the heating or heat dissipation requirements of the powertrain 700, etc. and that the heat generated by the components of the powertrain 700, etc. can be recovered by waste heat to heat other components, that is, reasonable heat exchange can also be performed between multiple loops.

It will be appreciated that as the performance requirements for the thermal management system increase, the thermal management system becomes more complex in architecture, has a large number of components, and has very discrete component mounting locations, so the pipeline arrangement and avoidance operations of the thermal management system are very complex. The number of channels and the performance of the multi-channel valve are critical in order to simplify the piping arrangement of the thermal management system.

In the related art, a water valve adopted in a thermal management system is generally one or a combination of a plurality of three-way valves, four-way valves and five-way valves, and the three-way valves, the four-way valves and the five-way valves are ball valves generally, namely, spherical valve cores are used as opening and closing members, and a motor and a gear set are used for driving a valve rod, so that the valve cores are driven by the valve rod to do rotary motion around the axis of the ball valve, thereby controlling the closing or the communication of channels in the ball valve, and further realizing the diversion, the confluence or the flow direction switching of media.

Only one valve core can be arranged in the ball valve, the valve core can rotate for 360 degrees at most, if the number of ports of the ball valve exceeds five, on one hand, the micro-channels of the valve core of the ball valve are increased, so that the processing is difficult, and the process cost is high; on the other hand, when the number of ports of the ball valve is increased, the ports interfere with each other, so that the internal flow passage is difficult to switch, the adjusting modes of the ball valve are fewer, and the switching of a plurality of adjusting modes cannot be met; on the other hand, the increase of the port number of the ball valve can lead to the increase of the contact area between the valve core and the sealing rubber, the large friction force can lead to the larger rotation moment of the ball valve, the requirement of the sealing compression amount is higher, the service life of the ball valve is easy to reduce, the cost is increased, the volume of the motor and the gear set is increased, and even the volume of the motor and the gear set occupies more than one half of the total volume of the ball valve. In summary, the related art scheme using ball valves as multi-channel valves is difficult to be applied to five-way and more multi-channel valves.

The multi-channel valve provided by the embodiment of the application aims to solve the technical problems in the related art.

The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

At least one liquid inlet groove 121 corresponds to two or more through holes 131, any two through holes 131 corresponding to the same liquid inlet groove 121, and two different liquid outlet grooves 111 respectively.

It should be noted that "corresponding to" refers to communication between the liquid inlet tank 121 and the through hole 131, and may also refer to that a projection of the through hole 131 on the liquid inlet tank 121 is located in the liquid inlet tank 121. Since the through holes 131 may communicate with the liquid inlet groove 121 and the liquid outlet groove 111, and one liquid inlet groove 121 corresponds to at least one through hole 131, the correspondence is not one-to-one correspondence, but one-to-one or one-to-many correspondence, and the correspondence between the liquid outlet groove 111 and the through holes 131 is the same.

The liquid such as refrigerant, cooling liquid and the like can enter the liquid inlet groove 121 through the liquid inlet port 122, then enter the liquid outlet groove 111 through the through hole 131, and are discharged from the liquid outlet port 112. It will be appreciated that one inlet port 122, one inlet tank 121, one through hole 131, one outlet tank 111 and one outlet port 112 may constitute one complete flow path of the multi-channel valve.
