[0002] A multi-way valve is a handle-operated rotary valve used to connect and control multiple pipelines. Its structure typically includes a valve body, valve core, end cap, actuator, and sealing ring. The valve body is designed with multiple parallel pipe joints and flow channels, and the valve core rotates to connect or isolate different flow channels, thereby achieving 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. Utility Model Content

[0004] In order to solve the above technical problems, the utility model 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] The four-way valve assembly includes 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 is driven to rotate by the actuator so that the valve core can be switched between the first state and the second state.

[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 includes the arbitrarily combinable thermal management multi-way valve as described above, and also includes 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 set at various key positions 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;

[0015] The power supply provides the required electrical energy to the controller and the actuator;

[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 embodiments described 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 making creative efforts 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 mounted 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 mounted on the upper side of the end cover 3 by a screw, the end cover sealing ring 6 is embedded in the end cover 3, and several 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 is driven to rotate by the actuator 4 so that the valve core 2 can be switched between the first state and the second state.

[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 utility model 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, and the clamp is eliminated. The valves are directly connected through joints.

[0048] This new valve core features a conical, integrally sealed design, along with the corresponding valve body. The sealing ring is installed within the valve body, creating a seamless seal between the core, sealing ring, and valve body. This avoids the structural flaw of conventional four-way valve assemblies, where the end cap and valve body are each sealed in half. This also eliminates internal leakage caused by this structural design flaw.

[0049] Internal leakage can significantly impact the thermal management and performance of the vehicle. It can lead to insufficient heating and cooling performance, or even loss of cooling and heating functions. It can also cause core components like the vehicle's motor, battery, and electronic control to lose functionality.

[0050] The four-way valve assembly of the utility model 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 utility model 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 to the four-way valve assembly in any direction. Through combination, any functional requirement of the thermal management water system of different vehicles can be built.

[0052] Theoretically, a complex thermal management water control system can be connected to 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 utility model is matched with the heat pump thermal management system of the whole vehicle, 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 the connecting pipe 15, the tee pipe 16, the inlet and outlet pipe joints 17, the plug cover 18 and the L-shaped elbow 19 and other components as required and installing them on the outside of the valve body 1, the required type of multi-way valve can be obtained.

[0065] Working mode 2: The valve core of four-way valve A 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 third channel of four-way valve B, and the first channel of four-way valve B is connected to the second channel of four-way valve B;

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

[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, thereby flexibly adjusting the fluid channel in the thermal management system. The sensor group is distributed throughout the key areas of the thermal management system, monitoring and recording key parameters such as temperature and pressure in real time, providing accurate data support for the controller; the intelligent logic built into 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 precisely 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 the motor and electronic control system, ensuring the stable operation of the thermal management system and energy efficiency optimization.
