Detailed ways

Embodiments of the present application may provide a vehicle, such as an automobile, a motorcycle, an airplane, a truck, a ship, a train engine, etc., the vehicle may be any vehicle that at least partially uses the electric energy stored in the vehicle to power the traction motor, Exemplarily, the vehicle may be a plug-in vehicle having a battery pack that may be charged through an external plug or using regenerative power derived from an electric motor.

FIG. 1 is a schematic diagram of a vehicle provided by an embodiment of the present application. Referring to FIG. 1 , the vehicle may include a thermal management system 300 and a device to be adjusted in temperature, and the thermal management system 300 is connected to the device to be adjusted in temperature to adjust the temperature of the device to be adjusted in temperature. The temperature-regulated device may include basic components such as a powertrain 700, a battery pack 400, an electronic device 500, and a passenger compartment 600, wherein the battery pack 400 is used to provide power to the electronic device 500, and the powertrain 700 may include, for example, a traction motor and a transmission The box, electronic device 500 can be used to drive the electric motor and gearbox to propel the travel of the vehicle. The passenger compartment 600 is the area inside the vehicle for a user to drive or ride in.

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

It should be noted that, what is not shown in the figure is that multiple external ports can be set in the refrigerant loop, multiple external ports can be set in the cooling liquid loop, and the multi-channel valve 100 itself has multiple liquid inlet ports and outlet ports. These ports can connect the powertrain 700, battery pack 400, electronic device 500, passenger compartment 600 and other components into the thermal management system 300, so that the thermal management system 300 can heat or cool these components.

The working principle of the refrigerant loop can be regarded as that the gaseous refrigerant enters the compressor 31 and is converted into a high-temperature and high-pressure refrigerant after being compressed by the compressor 31. The high-temperature and high-pressure refrigerant undergoes heat exchange at the condenser 32 and becomes The medium-temperature and medium-pressure refrigerant is turned into a gaseous refrigerant after heat exchange by the evaporator 33 and returns to the compressor 31. Therefore, the cooling liquid in the cooling liquid loop can absorb heat at the condenser 32 to heat the components such as the battery pack 400 connected in the loop, and the cooling liquid in the cooling liquid loop can dissipate heat at the evaporator 33 , to cool components such as the power assembly 700 connected in the loop.

The condenser 32 and evaporator 33 connected to the refrigerant circuit are water-cooled condensers and water-cooled evaporators. It should be understood that the cooling liquid circuit can also be connected to an air-cooled condenser, an air-cooled evaporator, and a heat sink through a multi-way valve. Heater modules, heaters and other devices enable the thermal management system to achieve more diverse cooling and heating modes.

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

It is not difficult to understand that as the performance requirements of the thermal management system gradually become higher, the structure of the thermal management system becomes more and more complex, the number of components is large, and the installation positions of the components are also scattered. Therefore, the piping layout and avoidance work of the thermal management system very complicated. In order to simplify the piping layout of the thermal management system, the number and performance of multi-channel valves are very important.

In related technologies, the water valves used in the thermal management system are generally a combination of one or more of three-way valves, four-way valves, and five-way valves. Generally, three-way valves, four-way valves, and five-way valves are all ball valves. , that is to use the spherical valve core as the opening and closing part, and use the motor and gear set to drive the valve stem, so that the valve core is driven by the valve stem to rotate around the axis of the ball valve, thereby controlling the closing or communication of the channel in the ball valve , and then realize the diversion, merging or switching of the flow direction of the medium.

Only one spool can be installed in the ball valve, and the spool can rotate up to 360 degrees. If there are more than five ports in the ball valve, on the one hand, the number of micro-channels in the ball valve spool will increase, which will lead to difficult processing and high process costs; If the number increases, the ports will interfere with each other, making it difficult to switch the internal flow path, so that the adjustment mode of the ball valve is less, which cannot meet the switching of multiple adjustment modes; on the other hand, the increase in the number of ports of the ball valve will lead to the valve core The contact area with the sealing rubber increases, and the friction force is large, which will lead to a greater rotational torque of the ball valve and a higher demand for sealing compression, which will not only easily lead to a reduction in the life of the ball valve and an increase in cost, but also cause damage to the motor and gear set. The volume increases, even occupying more than half of the total volume of the ball valve. In a word, the solution of using ball valves as multi-channel valves in the related art is difficult to apply to multi-channel valves with five-way ports and above.

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

The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

Since the through hole 131 can communicate with the liquid inlet tank 121 and the liquid outlet tank 111, and one liquid inlet tank 121 corresponds to at least one through hole 131, the correspondence here is not a one-to-one correspondence, but a one-to-one or one-to-many relationship , the corresponding relationship between the outlet groove 111 and the through hole 131 is the same.

Liquids such as refrigerant and coolant can enter the liquid inlet tank 121 through the liquid inlet port 122 , then enter the liquid outlet tank 111 through the through hole 131 , and be discharged from the liquid outlet port 112 .

The opening on the side wall 1102 and the liquid outlet pipe outside the opening together form a liquid outlet port 112.
