Description

[Technical Field]

[0001] This invention relates to the technical field of automotive parts, and in particular to a multi-way valve for switching control of coolant flow circuit in an automotive thermal management system and the automotive thermal management system itself. [Background Technology]

[0002] Multi-way valves are widely used in various technical fields and applications to control complex fluid flows. They can potentially replace combinations of multiple check valves. For example, multi-way valves are used to control complex fluid systems with fluid circuits in vehicles. Especially in new energy vehicles, such as hybrid or electric vehicles, the fluid systems and circuits are increasingly complex; for instance, the fluid circuit may be a cooling circuit and / or a heating circuit, thus the same fluid circuit can be designed as both a cooling and heating circuit. Depending on the operating mode, it may be necessary to close or open, connect or disconnect the fluid circuits of such a fluid system. When using traditional multi-way valves, multiple multi-way valves are required, such as 3 / 2- or 4 / 2-way valves.

[0003] A known multi-way valve includes a housing with multiple housing openings, each housing opening for flow connection to an external flow path of fluid, and a valve body disposed in the housing for rotation about a rotation axis for flow connection to at least two housing openings of the housing, wherein a sealing opening corresponding to the housing opening is disposed between the housing and the valve body for sealing the flow connection relative to the free environment, and wherein the valve body has at least one connection channel.

[0004] like Figure 1 The diagram shows a block diagram of a thermal management system for an electric vehicle. Ports H, I, J, K, L, M, N, and O are connected to other thermal management components via pipelines to manage the thermal performance of components in the vehicle that require cooling and / or heating. To achieve the various thermal management modes, three multi-way valves are introduced: two three-way valves A1 and A2, and one four-way valve A3. Adjusting the valve openings allows for specific pipeline connections, thus creating different thermal management modes. Figure 2 The diagram shows the opening degree definitions of the three multi-way valves under various thermal management modes. By controlling the opening and closing of different valve ports of the three multi-way valves, thermal management requirements under 11 modes can be met.

[0005] Existing thermal management systems for electric vehicles require the use of multiple multi-way valves and multiple valve actuators to control the switching of these valves. This results in large size and high cost. Furthermore, multiple multi-way valves require numerous pipelines and interfaces, leading to a high risk of system leakage. They also require a large installation space, and the use of multiple valve actuators also generates significant energy consumption.

[0006] In view of this, the designer has deeply conceived and actively researched and improved the design of the multi-way valve to develop this invention, addressing the many shortcomings and inconveniences caused by the imperfections in the multi-way valve structure design. [Summary of the Invention]

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-way valve that is smaller in size, saves costs, reduces the number of valve actuators, and can achieve multiple mode switching.

[0008] To achieve the above objectives, the solution of the present invention is:

[0009] A multi-way valve includes: a valve body and a valve core, the valve core being assembled inside the valve body and rotating relative to the valve body; the valve core being connected to an actuator; the valve body having six circumferentially distributed ports, namely X1 port, X2 port, X3 port, X4 port, X5 port, and X6 port arranged sequentially along the outer circumference of the valve body, wherein X1 port, X3 port, X4 port, and X5 port are located on the upper layer of the valve body, X2 port is located on the lower layer of the valve body, and X6 port connects the upper and lower layers; the valve core has an upper layer channel and an upper and lower layer mixed channel; the upper layer channel has ports A, B, and C, which are interconnected; the upper and lower layer mixed channel includes two ports D and E connecting the upper and lower layers and one port F in the lower layer, which are interconnected.

[0010] Furthermore, among the four ports on the upper layer of the valve housing, port X1 is arranged opposite to ports X3, X4 and X5, and port X2 is arranged opposite to port X6.

[0011] Furthermore, the angle between the X3 port and the X4 port is 40°, the angle between the X4 port and the X5 port is 40°, the angle between the X5 port and the X6 port is 50°, the angle between the X6 port and the X1 port is 70°, the angle between the X1 port and the X2 port is 100°, and the angle between the X2 port and the X3 port is 50°.

[0012] Furthermore, the valve housing has six protruding connectors integrally formed on its six ports, which protrude from the outer periphery of the valve housing.

[0013] Another objective of this invention is to overcome the shortcomings of the prior art and provide an automotive thermal management system that is smaller in size, saves costs, is easy to install, and reduces the use of valve actuators.

[0014] To achieve the above objectives, the solution of the present invention is:

[0015] A vehicle thermal management system using the aforementioned multi-way valve includes: a multi-way valve, a first electronic water pump, a second electronic water pump, a heat exchanger, a first water temperature sensor, a second water temperature sensor, a water-cooled condenser, and an expansion tank. The first electronic water pump is connected to the X3 port of the multi-way valve and the heat exchanger via a pipeline. The heat exchanger is connected to the first electronic water pump, the X4 port of the multi-way valve, and the second water temperature sensor via a pipeline. The second water temperature sensor is connected to the heat exchanger and the X5 port of the multi-way valve via a pipeline. The second electronic water pump is connected to the water-cooled condenser and the X6 port of the multi-way valve via a pipeline. The water-cooled condenser is connected to the second electronic water pump, the first water temperature sensor, and the X2 port of the multi-way valve via a pipeline. The first water temperature sensor is connected to the X1 port of the multi-way valve and the water-cooled condenser via a pipeline. The expansion tank is connected to the X6 port of the multi-way valve and the second electronic water pump via a pipeline.

[0016] By adopting the above solution, the present invention designs the valve core and valve shell of the multi-way valve as an upper and lower layer structure. The required thermal management mode is switched by whether the channel of the valve core is connected to the port of the valve shell. The function that originally required three multi-way valves can be achieved with one multi-way valve of the present invention. More working modes can be achieved with fewer valve shell ports. Thus, the overall size of the multi-way valve is smaller, which can save more space. At the same time, replacing three multi-way valves with one multi-way valve can also reduce the piping in the thermal management system and reduce the number of valve actuators required to control the switching of multi-way valves, which can save costs and reduce the energy consumption of valve actuators. Moreover, due to the reduction of piping and piping interfaces, the risk of leakage in the system will also be reduced. [Attached Image Description]

In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0063] like Figures 3 to 9As shown, the present invention discloses a multi-way valve 10, which includes a valve housing 1 and a valve core 2. The valve core 2 is assembled inside the valve housing 1, and the valve housing 1 and the valve core 2 can rotate relative to each other. The valve housing 1 is fixedly installed, and the valve core 2 is connected to an actuator. The valve housing 1 has six circumferentially distributed ports, namely X1 port, X2 port, X3 port, X4 port, X5 port, and X6 port. The X1 port, X3 port, X4 port, and X5 port are located on the upper layer of the valve housing 1, the X2 port is located on the lower layer of the valve housing 1, and the X6 port connects the upper and lower layers. The valve core 2 has an upper layer channel and an upper and lower layer mixed channel. The upper layer channel has ports A, B, and C, which can be interconnected through the channel. The upper and lower layer mixed channel includes two ports D and E that connect the upper and lower layers and one port F in the lower layer. The ports D, E, and F of the upper and lower layer mixed channel are interconnected.

[0064] As shown in the figure, among the four ports on the upper layer of the valve housing 1, port X1 is positioned opposite ports X3, X4, and X5, and port X2 is positioned opposite port X6. Preferably, the angle between ports X3 and X4 is 40°, the angle between ports X4 and X5 is 40°, the angle between ports X5 and X6 is 50°, the angle between ports X6 and X1 is 70°, the angle between ports X1 and X2 is 100°, and the angle between ports X2 and X3 is 50°. To facilitate pipeline connection, six connectors protruding from the outer periphery of the valve housing 1 are integrally formed on the six ports.

[0065] like Figures 10 to 43 This invention also discloses an automotive thermal management system, comprising the multi-way valve 10, a first electronic water pump 20, a second electronic water pump 30, a heat exchanger 40, a first water temperature sensor 50, a second water temperature sensor 60, a water-cooled condenser 70, and an expansion tank 80.

The heat exchanger 40 is connected to the first electronic water pump 20, the X4 port of the multi-way valve 10, and the second water temperature sensor 60 via a pipeline. 60 is connected to the heat exchanger 40 and the X5 port of the multi-way valve 10 via a pipeline. The second electronic water pump 30 is connected to the water-cooled condenser 70 and the X6 port of the multi-way valve 10 via a pipeline. The water-cooled condenser 70 is connected to the second electronic water pump 30, the first water temperature sensor 50 and the X2 port of the multi-way valve 10 via a pipeline. The first water temperature sensor 50 is connected to the X1 port of the multi-way valve and the water-cooled condenser 70 via a pipeline. The expansion tank 80 is connected to the X6 port of the multi-way valve 10 and the second electronic water pump 30 via a pipeline.

[0066] By controlling the valve core 2 of the multi-way valve 10 to rotate in the valve body 1 through the actuator, the connection or closure relationship between the channel of the valve core 2 and each port of the valve body 1 can be controlled, thereby controlling the circulation of coolant in the pipeline in 11 different modes.
