Description

Technical Field

[0001] The present disclosure relates to a manifold assembly and a multi-way valve. Background Art

[0002] The vehicle thermal management system usually includes a refrigerant circuit and a coolant circuit. The refrigerant circuit is mainly formed by connecting components such as a compressor, a heat exchanger, and a throttling device through pipes. In order to achieve the switching of vehicle thermal management modes (such as cooling mode, heat pump mode, etc.), it is usually necessary to set a variety of valves on the refrigerant circuit, such as multiple shut-off valves and / or multi-way valves. Such a system configuration not only makes the cost of the vehicle thermal management system higher, but also makes the control strategy more complicated.

[0003] Electric vehicles have a high demand for thermal management, but the layout space that can be provided for the vehicle thermal management system is limited. Therefore, the thermal management system of electric vehicles is developing in the direction of integration. At present, in order to realize the integration of the vehicle thermal management system, a manifold assembly that is basically in the shape of a plate is usually used to directly connect and communicate some components in the vehicle thermal management system. The above-mentioned parts can be directly arranged on the plate-shaped manifold assembly. In order to facilitate the switching of the fluid in the manifold assembly, a multi-way valve is usually installed on the manifold assembly, and the valve port of the multi-way valve is directly connected to the flow channel on the manifold assembly. Based on this connection method, a plurality of interfaces that are used in conjunction with the valve ports of the multi-way valve need to be correspondingly arranged on the manifold assembly. Since the relative positions of the interfaces on the manifold assembly are determined by the relative positions of the valve ports of the multi-way valve, the relative positions of the interfaces cannot be adjusted as needed, resulting in the design of the flow channel on the manifold assembly being not flexible enough. Summary of the invention

[0041] Below, see Figures 1 to 9 Embodiments of the present disclosure are described in detail.

[0042] like Figure 1 As shown, the multi-way valve 100 of the present disclosure includes a valve element and a connection block 7. The connection block 7 is also called a valve block, and has a mounting surface 1. The valve element is mounted on the mounting surface 1. The number of mounting surfaces 1 can be one or more. The number of valve elements can also be one or more, which is determined according to specific needs. The connection block 7 also has an interface surface 10, and an interface 17 is provided on the interface surface 10. The interface 17 can be used to communicate with components in the thermal management system of the vehicle, such as a water condenser, an evaporator condenser, an internal heat exchanger, etc. Figure 1 As shown, the interface surface 10 may be adjacent to the mounting surface 1. More specifically, the interface surface 10 may be adjacent to two mounting surfaces 1 respectively.

[0043] See again Figure 1 The valve element includes a first valve element 2 and a second valve element 3; the mounting surface 1 includes a first mounting surface 8 and a second mounting surface 9. The first valve element 2 is mounted on the first mounting surface 8; and the second valve element 3 is mounted on the second mounting surface 9. Specifically, the first valve element may be a five-way valve, and the second valve element may be an expansion valve. Figure 1 An example of two valve elements is shown. In other examples, only one valve element may be provided. Of course, more valve elements are also possible, and the present disclosure does not limit this. For example, the valve element may only include a first valve element 2 installed on the first mounting surface 8 or a second valve element 3 installed on the second mounting surface 9. Figures 1 to 3 As shown, the first mounting surface 8 and the second mounting surface 9 are opposite to each other and can be located at opposite sides of the connecting block 7, or at opposite ends of the connecting block 7, forming two end surfaces. In addition, the first mounting surface 8 and the second mounting surface 9 are flat surfaces for easy installation of the valve element.

[0044] like Figure 2 As shown, the first mounting surface 8 is provided with a first valve port V1, a second valve port V2, a third valve port V3, a fourth valve port V4 and a fifth valve port V5 which are respectively connected to the first valve element 2. Figures 2 to 5 As shown, the interface 17 includes a first main interface P4 and a second main interface P5; the interface 17 also includes a first secondary interface P1, a second secondary interface P2, a third secondary interface P3 and a fourth secondary interface P6. Figure 3 As shown, a three-way element 4 may also be provided in the connection block 7 .

[0045] like Figures 3 to 5 As shown, the first valve port V1 is connected to the first secondary port P1; the second valve port V2 is connected to the first main port P4; the third valve port V3 is connected to the first port A1 of the three-way element 4; the second port A2 of the three-way element 4 is connected to the third secondary port P3; the third port A3 of the three-way element 4 is connected to the second main port P5; the fourth valve port V4 is connected to the second secondary port P2; the fifth valve port V5 is connected to the fourth secondary port P6. The above communication is achieved through the flow channel or channel provided inside the connection block 7, and the above flow channel can be straight or bent or curved, depending on the specific application. It should be noted that the design of the flow channel should reduce the volume of the connection block as much as possible to make the structure more compact.

[0046] like Figure 2 and 3As shown, the interface surface 10 includes a main interface surface 12 and a secondary interface surface 11. The first main interface P4 and the second main interface P5 are respectively arranged on the main interface surface 12, which can be used to connect to external thermal management elements, such as through pipelines. The first secondary interface P1, the second secondary interface P2, the third secondary interface P3 and the fourth secondary interface P6 are respectively arranged on the secondary interface surface 11, which can be used to dock and communicate with the flow channel plate described below, and then achieve communication with the thermal management elements installed on the flow channel plate to achieve an integrated thermal management module. In addition, the main interface surface 12 and the secondary interface surface 11 are relatively arranged on both sides of the connecting block 7. For example, the main interface surface 12 and the secondary interface surface 11 can be parallel to each other and be flat surfaces, so as to facilitate installation on the flow channel plate described below.

[0047] The first mounting surface, the second mounting surface, the main interface surface, and the auxiliary interface surface mentioned above are arranged adjacent to each other, so that the structure of the multi-way valve assembly is more compact.

[0048] like Figure 1 , 3 As shown in FIG4 , the first auxiliary interface P1 and the third auxiliary interface P3 are provided with a protruding joint 20. The protruding joint 20 can protrude from the connection block 7, so it can be inserted into the corresponding port of the flow channel plate described below to achieve radial sealing with the flow channel plate. Different from this, the second auxiliary interface P2 and the fourth auxiliary interface P6 can achieve end surface connection and end surface sealing with the flow channel plate.

[0049] See again Figure 2 and 3 The second valve element 3 is disposed between the third secondary port P3 and the second port A2 of the three-way element 4. In other words, the fluid flows through the second valve element 3 or the valve cavity of the second valve element 3 between the third secondary port P3 and the second port A2 of the three-way element 4.

[0050] For example, the first main interface P4 and the second main interface P5 can be respectively connected to the evaporator-condenser in the thermal management system, the first secondary interface P1 can be connected to the water condenser in the thermal management system, the third secondary interface P3 can be connected to the battery refrigerator in the thermal management system, the second secondary interface P2 can be connected to the internal heat exchanger in the thermal management system, and the fourth secondary interface P6 can be connected to the internal heat exchanger in the thermal management system. Other connection or communication methods are also possible.

[0051] When the multi-way valve 100 of the present disclosure includes a first valve element that is a five-way valve and a second valve element that is an expansion valve, the multi-way valve 100 as a whole constitutes an integrated six-way valve assembly, which has a total of six interfaces, namely the two main interfaces and four secondary interfaces described above. By controlling the connectivity state of the first valve element 2 and the second valve element 3, the connectivity state of the six interfaces of the six-way valve assembly can be adjusted, thereby assisting in the mode switching of the thermal management system and simplifying the system structure and control. In addition, by providing a connecting block, not only an integrated multi-way valve can be realized, but it can also be flexibly applied to the flow channel plate described below to realize an integrated manifold assembly or an integrated thermal management module.

[0052] The first valve element 2 may include a first actuator, a first valve core, and a first valve body. The first valve body includes a first valve cavity and five openings connected to the first valve cavity and respectively connected to the five valve ports. Figure 2 As shown, the first valve cavity V0 of the first valve element 2 is a recessed portion of the connecting block 7 at the first mounting surface 8. In other words, part of the connecting block 7 forms the first valve cavity V0 of the first valve element 2, and the joint surface between the first valve element 2 and the connecting block 7 is the first mounting surface 8. The first valve core is rotatably arranged in the first valve cavity, and the first actuator is used to drive the first valve core to switch between the first position and the second position. When the first valve core is located at the first position, the first valve port V1 and the second valve port V2 of the above five valve ports are connected, the third valve port V3 and the fifth valve port V5 are connected, and the fourth valve port V4 is not connected. When the first valve core is located at the second position, the first valve port V1 and the fifth valve port V5 of the above five valve ports are connected, the second valve port V2 and the fourth valve port V4 are connected, and the third valve port V3 is not connected. Since the first valve body and the first valve cavity of the first valve element are at least partially formed on the connecting block, not only the manufacturing material is saved, but also the structure of the multi-way valve is more compact, the sealing effect is better, and the assembly is simpler.

[0053] The second valve element 3 may include a second actuator, a second valve core and a second valve body. The second valve body includes a second valve cavity B0 and openings B1 and B2 connected to the third secondary port P3 and the second port A2 of the three-way element 4, respectively. Figure 3 As shown, the second valve cavity B0 is a recessed portion at the second mounting surface 9. In other words, part of the connecting block 7 forms the second valve cavity B0 of the second valve element 3, and the joint surface between the second valve element 3 and the connecting block 7 is located in the connecting block 7. The second valve core is arranged in the second valve cavity, and the second actuator is transmission-connected to the second valve core for driving the second valve core to move, so that the expansion valve as the second valve element has at least two states, namely, closed and throttling. The expansion valve can be a needle valve or a ball valve. The specific structure of the expansion valve is known and will not be described here. Since the second valve body and the second valve cavity of the second valve element are at least partially formed on the connecting block, not only the manufacturing material is saved, but also the structure of the multi-way valve is made more compact, the sealing effect is better, and the assembly is simpler.

[0054] like Figure 6 As shown, the manifold assembly 200 of the present disclosure includes: a flow channel plate 5, a valve element and a connecting block 7. The connecting block 7 is arranged on one side of the flow channel plate 5 and is connected to the flow channel plate 5. The connecting block 7 has a mounting surface 1, and various elements of the vehicle thermal management system can be mounted on the mounting surface 1 as needed. For example, the mounting surface 1 can be perpendicular to the flow channel plate 5. The number of mounting surfaces 1 can be multiple. The valve element is mounted on the mounting surface 1 and is connected to the flow channel plate 5 through the connecting block 7. The number of valve elements can be one or more, which is determined specifically according to needs. In addition, as Figure 7 As shown, the connection block 7 has an interface surface 10. An interface 17 is provided on the interface surface 10. The interface 17 can be used to communicate with components in the vehicle thermal management system or external components of the thermal management integrated module, such as communicating with the evaporator condenser. Figures 6 to 8 As shown, the interface surface 10 can be adjacent to the mounting surface 1. The interface surface 10 can be adjacent to two mounting surfaces 1 respectively. For example, the interface surface 10 is parallel to the flow channel plate 5.

[0055] For example, the valve element may include a first valve element 2 and / or a second valve element 3. Specifically, the mounting surface 1 may include a first mounting surface 8 and / or a second mounting surface 9. The first valve element 2 is mounted on the first mounting surface 8; and / or the second valve element 3 is mounted on the second mounting surface 9. Figures 6 to 8 2 shows a case where the manifold assembly 200 includes two valve elements, and the connection block 7 has two mounting surfaces 8 and 9 adjacent to each other. In other words, the first mounting surface 8 is adjacent to the second mounting surface 9. In addition, the first mounting surface 8 and the second mounting surface 9 may be perpendicular to each other. The first valve element 2, which is a five-way valve, is mounted on the first mounting surface 8, and the second valve element 3, which is an expansion valve, is mounted on the second mounting surface 9. In other embodiments, the first mounting surface 8 and the second mounting surface 9 may be arranged on both sides of the connection block 7, as described above with reference to Figures 1 to 5 described.

[0056] like Figure 8 As shown, the connection block 7 can be integrally formed with the flow channel plate 5. In this way, the integration of the manifold assembly can be improved.

The above-mentioned channels can be integrally formed with the flow channel plate 5 to further improve the degree of integration. One end of the channel is connected to the connecting block 7, and the other end is connected to the thermal management elements provided in the vehicle thermal management system, and these elements can be provided on the flow channel plate. For example, the other end of the first channel C1 can be connected to the water condenser in the thermal management system, the other end of the second channel C2 can be connected to the battery refrigerator in the thermal management system, the other end of the third channel C3 can be connected to the internal heat exchanger in the thermal management system, and the other end of the fourth channel C4 can be connected to the internal heat exchanger in the thermal management system.

[0058] like Figure 8 As shown, the first mounting surface 8 of the connection block 7 is provided with a first valve port V1, a second valve port V2, a third valve port V3, a fourth valve port V4 and a fifth valve port V5 which are respectively connected to the first valve element 2. The second mounting surface 9 of the connection block 7 is provided with a mounting port 16 which is connected to the second valve element 3. The interface 17 on the interface surface 10 of the connection block 7 includes a first main interface P4 and a second main interface P5. The first main interface P4 and the second main interface P5 are used to communicate with the thermal management element outside the thermal management integrated module through pipelines. In addition, a three-way element 4 (not shown here) is provided in the connection block 7, and the details are shown in the above description for Figures 1 to 5 , especially Figure 3 as described.

[0059] In the embodiment where the connecting block 7 and the flow channel plate 5 are integrally formed, the first valve port V1 is connected to the first channel C1 of the flow channel plate 5; the second valve port V2 is connected to the first main interface P4; the third valve port V3 is connected to the first port A1 of the three-way element 4; the second port A2 of the three-way element 4 is connected to the second channel C2 of the flow channel plate 5; the third port A3 of the three-way element 4 is connected to the second main interface P5; the fourth valve port V4 is connected to the third channel C3 of the flow channel plate 5; the fifth valve port V5 is connected to the fourth channel C4 of the flow channel plate 5. The second valve element 3 is arranged between the second channel C2 of the flow channel plate 5 and the second port A2 of the three-way element 4.

[0060] In the embodiment where the connection block 7 is not integrally formed with the flow channel plate 5, the connection block 7 further comprises an interface surface 10 facing the flow channel plate 5, on which an interface 17 is also provided. The interface 17 on the interface surface 10 of the connection block 7 facing the flow channel plate 5 comprises a first secondary interface P1, a second secondary interface P2, a third secondary interface P3 and a fourth secondary interface P6, as described above in conjunction with Figures 1 to 5The first valve port V1 is connected to the first auxiliary port P1, and the first auxiliary port P1 is connected to the first channel C1; the second port A2 is connected to the third auxiliary port P3, and the third auxiliary port P3 is connected to the second channel C2 of the flow channel plate 5; the fourth valve port V4 is connected to the second auxiliary port P2, and the second auxiliary port P2 is connected to the third channel C3; the fifth valve port V5 is connected to the fourth auxiliary port P6, and the fourth auxiliary port P6 is connected to the fourth channel C4.

The secondary interface surface 11 is used to connect with the flow channel plate 5.

[0062] Combination Figures 1 to 5 ,in particular Figure 3 As shown, the second valve element 3 may be arranged between the third secondary port P3 and the second port A2 of the three-way element 4 .

[0063] The present invention transfers the position of the external interface on the flow channel plate to the connection block by setting a connection block between the valve element and the flow channel plate, so that the position of the external interface on the flow channel plate is not restricted and can be adjusted as needed, simplifying the flow channel arrangement and improving the flexibility of the flow channel design on the flow channel plate. By setting the main interface connected to the external element on the interface surface of the connection block, it is avoided that the operating space when connecting the fluid pipeline used to connect the main interface to the external element is limited due to the installation of some thermal management elements on the manifold assembly, resulting in the technical problem of inconvenient installation; at the same time, the flow channel design on the flow channel plate can be simplified, further improving the flexibility of the flow channel design in the flow channel plate.
