Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a multi-way valve and a vehicle. Background Technology

[0002] In related technologies, vehicle thermal management air conditioning systems typically involve multiple operating modes, such as passenger compartment cooling, battery cooling, and heat pump heating. To switch refrigerant flow paths between different modes, multiple solenoid valves are often installed in the refrigerant piping. To prevent refrigerant backflow, additional one-way valves are also required in the piping. While this combination configuration can meet complex thermal management requirements, it also brings a series of technical challenges.

[0003] Specifically, the system contains a large number of solenoid valves and check valves, leading to an increased number of components in the thermal management system, a complex system structure, and low integration. This not only increases the difficulty of system layout but also enhances the complexity of piping connections and the potential risk of leakage. Furthermore, the coordinated control of multiple solenoid valves requires high precision, increasing the complexity of the control strategy and placing higher demands on system response speed and reliability. In addition, the increased number of components directly drives up the cost of the vehicle's thermal management system, which is detrimental to overall vehicle cost control.

[0004] Therefore, simplifying the refrigerant loop structure, improving integration, and reducing system costs while meeting complex thermal management functions have become important directions for the optimization of current automotive heat pipe system technology. Utility Model Content

[0030] Reference Figure 1 , Figure 2 A multi-way valve 100 according to an embodiment of the present utility model includes: a base 10, a first three-way valve 20 and a second three-way valve 30.

[0031] The base 10 has at least five openings 11. A first three-way valve 20 and a second three-way valve 30 are disposed on the base 10. The first three-way valve 20 has three first valve ports 21, and the second three-way valve 30 has three second valve ports 31. One of the three first valve ports 21 and one of the three second valve ports 31 are connected to the same opening 11. The other two of the three first valve ports 21 are respectively connected to a single opening 11, and the other two of the three second valve ports 31 are respectively connected to a single opening 11.

[0032] The first three-way valve 20 and the second three-way valve 30 are mounted on the base 10. The three first valve ports 21 on the first three-way valve 20 are connected to the openings 11 on the base 10, and the three second valve ports 31 on the second three-way valve 30 are connected to the openings 11 on the base 10. By controlling the first three-way valve 20 and the second three-way valve 30, at least five openings 11 can switch between each other.

[0033] The base 10 of the multi-way valve 100 is provided with at least five openings 11. The multi-way valve 100 can be a five-way valve or a multi-way valve 100.

[0034] In related technologies, vehicle thermal management air conditioning systems typically involve multiple operating modes, such as passenger compartment cooling, battery cooling, and heat pump heating. To switch refrigerant flow paths between different modes, multiple solenoid valves are often installed in the refrigerant piping. To prevent refrigerant backflow, additional one-way valves are also required in the piping. While this combination configuration can meet complex thermal management requirements, it also brings a series of technical challenges.

[0035] Specifically, the system contains a large number of solenoid valves and check valves, leading to an increased number of components in the thermal management system, a complex system structure, and low integration. This not only increases the difficulty of system layout but also enhances the complexity of piping connections and the potential risk of leakage. Furthermore, the coordinated control of multiple solenoid valves requires high precision, increasing the complexity of the control strategy and placing higher demands on system response speed and reliability. In addition, the increased number of components directly drives up the cost of the vehicle's thermal management system, which is detrimental to overall vehicle cost control.

[0036] Therefore, simplifying the refrigerant circuit structure, improving integration, and reducing system costs while meeting complex thermal management functions have become important directions for the optimization of current automotive thermal management system technology.

[0037] In this embodiment of the invention, a first three-way valve 20 and a second three-way valve 30 are provided on the base 10, and at least five openings 11 are provided on the base 10. One of the three first valve ports 21 and one of the three second valve ports 31 are connected to the same opening 11, and the other two of the three second valve ports 31 are respectively connected to a single opening 11. The multiple openings 11 can be switched and connected. This embodiment of the invention forms a multi-way valve 100 with higher integration by combining two three-way valves. It can be a five-way valve or a valve with more or more passages, which improves integration, reduces the number of parts, optimizes the overall structure, reduces the difficulty of system layout, reduces the complexity of pipeline connection and potential leakage risk, reduces control requirements, reduces the complexity of control strategy, reduces the requirements for system response speed and reliability, and reduces the cost of the vehicle thermal management system, thus forming an advantage in vehicle cost control.

The same opening 11 is connected to both the first valve port 21 and the second valve port 31. The refrigerant can flow from the same opening 11 to the first valve port 21 and the second valve port 31, or from the first valve port 21 to the opening 11 and from the second valve port 31 to the opening 11.

[0040] Specifically, both the first three-way valve 20 and the second three-way valve 30 are three-way valves. The three-way valves can be equipped with a control board for easy use, or they can be electrically connected to control components to improve versatility.

[0041] Specifically, the multi-way valve 100 is a five-way valve, with five openings 11 on the base 10.
