[0002] A multi-way valve is a handle rotary valve that connects and controls multiple pipelines. Its structure usually includes valve body, valve core, end cover, actuator, sealing ring and other components. The valve body is designed with multiple parallel pipe joints and flow channels, and the valve core connects or isolates different flow channels through rotation, thereby realizing the switching control of the fluid medium.

[0003] In traditional technologies, fluid control valves often adopt fixed or limited switchable channel designs, which greatly limits the flexible adjustment of fluid flow direction and flow rate. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a thermal management multi-way valve that can be arbitrarily combined to solve the problem that fluid control valves in the prior art often adopt a fixed or limited switchable channel design, which greatly limits the flexible adjustment of fluid flow direction and flow rate.

[0005] A thermal management multi-way valve capable of being arbitrarily combined, comprising:

[0006] It comprises a four-way valve assembly, which comprises a valve body, a valve core, an end cover, an actuator, a valve core sealing ring, an end cover sealing ring, a valve core shaft sealing ring and a shock-absorbing pad. The end cover is fixedly mounted on the upper side of the valve body, the valve core is rotatably embedded in the interior of the valve body, the valve core sealing ring is embedded in the interior of the valve body, the actuator is fixedly mounted on the upper side of the end cover by a screw, the end cover sealing ring is embedded on the end cover, and a plurality of shock-absorbing pads are mounted on the edge of the valve body;

[0007] A partition is provided in the middle of the valve core, and a first channel, a second channel, a third channel and a fourth channel are provided on the outside;

[0008] The valve core has two working states: in the first state, the first channel and the second channel are connected, and the third channel and the fourth channel are connected; in the second state, after the valve core rotates 90 degrees, the first channel and the fourth channel are connected, and the second channel and the third channel are connected;

[0009] The valve core can be switched between the first state and the second state by driving the valve core to rotate through the actuator.

[0010] Preferably, it also includes a connecting pipe, a tee pipe, an inlet and outlet water pipe joint, a plugging cover and an L-shaped elbow installed on the outside of the valve body in any combination.

[0011] Preferably, the valve core and valve body of the four-way valve assembly both adopt a conical integral sealing design.

[0012] A arbitrarily combinable thermal management multi-way valve control system comprises the arbitrarily combinable thermal management multi-way valve as described above, and further comprises a controller, a sensor group and a power supply;

[0013] The controller is electrically connected to the actuator and is used to control the start, stop and rotation direction of the actuator, thereby controlling the switching of the valve core between the first state and the second state;

[0014] The sensor group is arranged at each key position of the thermal management system to monitor the temperature and pressure parameters in the thermal management system in real time and feed the monitoring data back to the controller;

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 5 As shown:

[0039] Embodiment 1: The present invention provides a thermal management multi-way valve that can be arbitrarily combined, including:

[0040] The four-way valve assembly includes a valve body 1, a valve core 2, an end cover 3, an actuator 4, a valve core sealing ring 5, an end cover sealing ring 6, a valve core shaft sealing ring 7 and a shock-absorbing pad 8. The end cover 3 is fixedly installed on the upper side of the valve body 1, the valve core 2 is rotatably embedded in the interior of the valve body 1, the valve core sealing ring 5 is embedded in the interior of the valve body 1, the actuator 4 is fixedly installed on the upper side of the end cover 3 through a screw, the end cover sealing ring 6 is embedded on the end cover 3, and a plurality of shock-absorbing pads 8 are installed on the edge of the valve body 1;

[0041] A partition is provided in the middle of the valve core 2, and a first channel 11, a second channel 12, a third channel 13 and a fourth channel 14 are provided on the outside;

[0042] The valve core 2 has two working states: in the first state, the first channel 11 and the second channel 12 are connected, and the third channel 13 and the fourth channel 14 are connected; in the second state, after the valve core 2 rotates 90 degrees, the first channel 11 and the fourth channel 14 are connected, and the second channel 12 and the third channel 13 are connected;

[0043] The valve core 2 can be switched between the first state and the second state by driving the valve core 2 to rotate through the actuator 4 .

[0044] From the above, we can see that when the connection status of the channel needs to be changed, such as Figure 3 , the valve core 2 is driven to rotate 90 degrees by the actuator 4, so that the valve core 2 can be switched from the first state to the second state;

[0045] The actuator 4 is fixedly mounted on the upper side of the end cover 3 via a screw, and can drive the valve core 2 to rotate.

[0046] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that it further includes a connecting pipe 15, a tee pipe 16, an inlet and outlet pipe joint 17, a plug cover 18 and an L-shaped elbow 19 installed in any combination on the outside of the valve body 1;

[0047] Among them, the four-way valve assembly of the present invention is a four-way valve assembly and its accessories that can be arbitrarily combined into a multi-way valve. The valves can be directly connected to each other, the inlet and outlet pipes of the four-way valve assembly are eliminated, the intermediate connecting water pipe is eliminated, the clamp is eliminated, and the valves are directly connected through joints.

[0048] The valve core of the present invention is a conical integral sealing design, and the corresponding valve body is also a conical integral sealing design. The sealing ring is installed inside the valve body, and the valve core, the sealing ring, and the valve body are integrally sealed. The structural defect of the traditional four-way valve assembly design in which the end cover and the valve body are each sealed half is avoided. Internal leakage due to structural design defects is avoided.

[0049] Internal leakage will have a great impact on the thermal management function and performance of the vehicle. It may lead to insufficient heating and cooling performance, or loss of cooling and heating functions. It may cause the core parts of the vehicle such as motors, batteries, and electronic controls to lose their functions.

[0050] The four-way valve assembly of the present invention can realize the functions of a one-way valve and a three-way valve without replacing the valve core.

[0051] The four-way valve assembly of the present invention is a universal part. The mounting point of the valve body of the four-way valve assembly and the mounting hole of the water pipe joint are designed to be completely symmetrical, so that the four-way valve assembly can be connected in any direction. Through combination, any functional requirements of the thermal management water system of different vehicles can be built.

[0052] Theoretically, it can be connected into a complex thermal management water control system with countless joints. Combined with the cooling system, it can realize thermal management functions such as vehicle cab heating, battery cooling and heating, electronic control system cooling, motor cooling and motor waste heat recovery, and vehicle heat pump;

[0053] When the four-way valve assembly of the present invention is matched with a whole vehicle heat pump thermal management system, there is no need to invest in early design and development and mold development, which greatly saves early design costs and mold costs.

[0061] Specifically, the valve core 2 and the valve body 1 of the four-way valve assembly both adopt a conical integral sealing design.

[0062] As can be seen from the above, by combining and installing the connecting pipe 15, the three-way pipe 16, the inlet and outlet pipe joints 17, the plugging cover 18 and the L-shaped elbow 19 and other components to the outside of the valve body 1 according to the requirements, a multi-way valve of the required type can be obtained.

[0063] like Figure 6 As shown, the four-way valve A and the four-way valve B are connected, and the second channel of the four-way valve A and the fourth channel of the four-way valve B are connected through a connecting pipe, which has the following working modes;

[0066] Working mode 3: The valve core of four-way valve A rotates 90 degrees, the valve core of four-way valve B rotates 90 degrees, the first channel of four-way valve A is connected to the fourth channel of four-way valve A, the third channel of four-way valve A is connected to the first channel of four-way valve B, and the second channel of four-way valve B is connected to the third channel of four-way valve B;

[0067] Working mode 4: The valve core of four-way valve B rotates 90 degrees, the first channel of four-way valve A is connected with the first channel of four-way valve B, and the third channel of four-way valve A is connected with the fourth channel of four-way valve A.

[0069] The controller is electrically connected to the actuator and is used to control the start, stop and rotation direction of the actuator, thereby controlling the switching of the valve core between the first state and the second state;

[0070] The sensor group is set at various key parts of the thermal management system to monitor the temperature and pressure parameters in the thermal management system in real time and feed the monitoring data back to the controller;

[0071] The power supply provides the required electrical energy to the controller and actuator;

[0072] The controller has built-in mode selection and switching logic, which can automatically select heat pump mode or non-heat pump mode according to the current thermal management needs;

[0073] The controller receives real-time monitoring data from the sensor group to determine the current state of the thermal management system, and adjusts the channel connection state of the four-way valve assembly accordingly to achieve thermal management tasks in different modes;

[0075] Heat pump mode: cab heating, battery heating, motor cooling, electric control cooling, motor waste heat recovery;

[0076] Non-heat pump mode: cab heating, battery heating, battery heating, motor cooling, and electric control cooling.

[0077] As can be seen from the above, the controller of this system is electrically connected to the actuator, and can accurately control the switching of the valve core between the two working states, so as to flexibly adjust the fluid channel in the thermal management system. The sensor group is distributed throughout the key areas of the thermal management system, and real-time monitoring and recording of key parameters such as temperature and pressure provide accurate data support for the controller; the built-in intelligent logic of the controller can automatically select and switch to heat pump mode or non-heat pump mode according to real-time data to meet different thermal management needs; by accurately adjusting the channel connection of the four-way valve, this system can efficiently perform multiple tasks such as cab heating, battery temperature management, cooling and heating of motors and electronic control systems, ensuring the stable operation of the thermal management system and energy efficiency optimization.
