[0032] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] In related technologies, valve seats are typically divided into two parts: a thicker body and a thinner sealing plate. The internal channels of the valve seat body are mostly formed into grooves using a die-casting process, and then the body and sealing plate are combined into one piece using a brazing process. This technology has a significant risk of leakage, a high rate of defective products in mass production, and consequently, increased manufacturing costs.

[0034] The following is for reference. Figures 1-8 A valve assembly 1 according to an embodiment of the present invention is described.

[0035] The valve assembly 1 for a thermal management system according to the present invention includes a valve seat 11, a valve body 12, a connecting pipe 13, and a heat exchanger 14.

[0036] The valve seat 11 has a valve mounting cavity 114, and a connection channel communicating with the valve mounting cavity 114 is formed inside the valve seat 11. The valve seat 11 also has multiple interfaces communicating with the connection channel, including at least one first interface 111 and at least one second interface 112. There can be multiple valve mounting cavities 114, each corresponding to at least one interface via the connection channel. Any two or more valve mounting cavities 114 can communicate with each other, or each valve mounting cavity 114 can be isolated from each other.

[0037] At least a portion of the valve body 12 is housed within the valve mounting cavity 114 and is adapted to control the flow of media within the connection channel. The valve body 12 can be configured as at least one of an expansion valve, a solenoid valve, or a check valve; alternatively, it can be configured as other types of valve structures. Multiple valve bodies 12 are provided, each housed within a corresponding valve mounting cavity 114. The media flowing through the connection channel can be refrigerant or water, etc. After passing through the corresponding valve body 12, the medium is either opened, blocked, or depressurized. The solenoid valve controls whether the medium flowing through it is opened or blocked by energizing its internal inductor coil. The check valve controls the flow direction of the medium, ensuring that the medium in the connection channel flows only in a preset direction, preventing reverse flow. Multiple valve bodies 12 can be used in combination to achieve better heat exchange performance.

[0038] One end of the connecting pipe 13 is connected to an interface on the valve seat 11, and a heat exchange interface 141 is formed on the heat exchanger 14. The interface is configured as multiple interfaces, including a first interface 111 and a second interface 112. The connecting pipe 13 is also configured as multiple interfaces, with the number of connecting pipes 13 being less than the number of interfaces. One end of each connecting pipe 13 is connected to the first interface 111, and the other end of each connecting pipe 13 is connected to at least one of the second interface 112 and the heat exchange interface 141. When one end of the connecting pipe 13 is connected to the first interface 111 and the other end of the connecting pipe 13 is connected to the heat exchange interface 141, the connecting pipe 13 enables the connection between the valve seat 11 and the heat exchanger 14. When one end of the connecting pipe 13 is connected to the first interface 111 and the other end of the connecting pipe 13 is connected to the second interface 112, the connecting pipe 13 enables the connection between different interfaces on the valve seat 11. When one end of the connecting pipe 13 is connected to the first interface 111 and the other end of the connecting pipe 13 is connected to both the heat exchange interface 141 and the second interface 112, the connecting pipe 13 enables the connection between the valve seat 11 and the heat exchanger 14, as well as the connection between different interfaces on the valve seat 11.

[0039] This invention connects the valve seat 11 to the heat exchanger 141 via the connecting pipe 13, thereby achieving communication between the valve seat 11 and the heat exchanger 14, as well as between different interfaces on the valve seat 11. This significantly reduces the structural manufacturing difficulty and cost of the valve seat 11, and makes the assembly and maintenance of the valve assembly 1 more convenient. Compared to the brazing process used for the valve seat 11, this invention utilizes the connecting pipe 13 to achieve communication between the valve seat 11 and the heat exchanger 14, as well as between different interfaces on the valve seat 11. It eliminates the need to form complex flow channels inside the valve seat 11 using brazing, making the assembly and maintenance of the valve assembly 1 of this invention more convenient, and reducing production and manufacturing difficulty.

[0040] According to one embodiment of the present invention, at least two connecting pipes 13 are constructed as a single integral part. Constructing at least two connecting pipes 13 as a single integral part can improve the integration of the valve assembly 1, reduce the number of parts, and at the same time reduce the assembly difficulty between the connecting pipes 13 and the valve seat 11 and the heat exchanger 14. The connection between the connecting pipes 13 and the valve block and the heat exchanger 14 is more convenient, and the development and mold opening costs of a single connecting pipe 13 are further reduced.

[0041] According to one embodiment of the present invention, the connecting pipe 13 and at least one of the valve seat 11 and heat exchanger 14 are integrally formed. When the connecting pipe 13 and the valve seat 11 are integrally formed, one end of the connecting pipe 13 is integrally formed with at least one of the first interface 111 and the second interface 112, and the other end of the connecting pipe 13 is connected to the heat exchange interface 141 to connect the heat exchanger 14 and the valve seat 11, so that the medium circulates between the valve seat 11 and the heat exchanger 14. When the connecting pipe 13 and the heat exchanger 14 are integrally formed, the other end of the connecting pipe 13 is directly integrally formed with the heat exchange interface 141, and one end of the connecting pipe 13 is selected to be connected to at least one of the first interface 111 and the second interface 112 according to different thermal management conditions. When the connecting pipe 13, the valve seat 11, and the heat exchanger 14 are integrally formed, the connecting pipe 13 is directly connected to the valve seat 11 and the heat exchanger 14 respectively, which is convenient for assembly. By integrating the connecting pipe 13 with at least one of the valve seat 11 and heat exchanger 14 into a single molded component, the valve assembly 1 used for thermal management becomes more integrated, has fewer parts, and further reduces costs.

[0042] According to the valve assembly 1 for a thermal management system of the present invention, the valve seat 11 has a first surface and a second surface, which are respectively disposed on both sides of the valve seat 11 in the thickness direction. A valve mounting cavity 114 has an opening formed on the first surface, and a first interface 111 and a second interface 112 are provided on the second surface. The valve body 12 is received within the valve mounting cavity 114 through the opening on the first surface, making the assembly of the valve body 12 more convenient and the machining of the valve mounting cavity 114 easier. The connection channel does not need to be overly complex. The fit between the valve seat 11 and the connecting pipe 13 replaces the method of forming a groove in the valve seat 11 body using a die-casting process in related technologies, making the assembly of the valve assembly 1 and the valve body 12 simpler and more convenient. The first interface 111 and the second interface 112 are provided on the second surface, and the heat exchanger 14 is connected to the valve seat 11 through the connecting pipe 13, simplifying assembly and saving space.

[0043] According to one embodiment of the present invention, two heat exchangers 14 are configured, spaced apart, with a heat exchange interface 141 disposed between the two heat exchangers 14 and open to each other. During the connection of the heat exchangers 14 to the heat exchange interface 141, the connecting pipe 13 is disposed between the two heat exchangers 14. Depending on different heat exchange conditions, the connecting pipe 13 can be connected to different heat exchange interfaces 141. This arrangement of the heat exchangers 14 and the connecting pipe 13 saves space and facilitates maintenance and replacement of the heat exchangers 14. Furthermore, since the connecting pipe 13 is located between the two heat exchangers 14, it is not exposed to the outside, and the heat exchangers 14 effectively protect the connecting pipe 13.

[0044] According to one embodiment of the present invention, the valve seat 11 has a third surface on its side, and the interface further includes a third interface 113, which is disposed on the third surface and communicates with the connection channel. The thermal management system has different heat exchange pipelines and heat exchange units. The third interface 113 is connected to different heat exchange pipelines and heat exchange units to meet different heat exchange conditions. Since the third interface 113 is disposed on the third surface on the side of the valve seat 11 and communicates with the connection channel, the medium flows between the valve body 12 and the valve seat 11. When the third interface 113 is connected to different heat exchange pipelines and heat exchange units, the flow of the medium in different heat exchange pipelines and heat exchange units can be easily realized to cope with different heat exchange conditions. The third interface 113 can be configured as an interface for connecting the valve assembly 1 to other heat exchange units, such as cooling channels for electric motors, cooling channels for battery modules, and indoor air conditioners.

[0045] The following is a brief description of the connecting pipe 13 according to the present invention.

[0046] The connecting pipe 13 according to the present invention is applied in the valve assembly 1 described in any of the above embodiments. The connecting pipe 13 includes a pipe body with a pipe channel formed within it suitable for conducting a medium; a first connector 131 disposed at one end of the pipe body and adapted to connect with a first interface 111; a second connector 132 disposed at the other end of the pipe body and adapted to communicate with a heat exchange interface 141; and a third connector 133 disposed on the pipe body and communicating with the pipe channel, adapted to communicate with a second interface 112.

[0047] The connecting pipe 13 connects to the first interface 111 via the first connector 131 to achieve communication with the valve seat 11, and connects to the heat exchange interface 141 via the second connector 132 to achieve communication with the heat exchanger 14. The connecting pipe 13 achieves communication between the valve seat 11 and the heat exchanger 14 via the first connector 131 and the second connector 132, enabling the flow of the medium between the valve seat 11, the pipe channel, and the heat exchanger 14. The third connector 133 is disposed on the pipe body and communicates with the pipe channel. The third connector 133 is adapted to communicate with the second interface 112. The connecting pipe 13 connects to the first interface 111 via the first connector 131 and connects to the second interface 112 via the third connector 133, achieving communication between different interfaces on the surface of the valve seat 11.

[0048] The connecting pipe 13 according to the present invention further includes a branch pipe 134, one end of which is connected to the third connector 133, and the other end of which is connected to the pipe body and connected to the pipe channel.

[0049] One end of the branch pipe 134 is connected to the third connector 133 and connected to the second interface 112, so as to realize the flow of the medium between different second interfaces 112 on the surface of the valve seat 11. The other end of the branch pipe 134 is connected to the pipe body and connected to the pipe channel. The medium flows into the branch pipe 134 through the second interface 112 and flows into the heat exchanger 14 through the pipe channel to achieve heat exchange. The branch pipe 134 provides more flow channels for the medium to flow, thereby achieving better heat exchange effect.

[0050] According to the present invention, the connecting pipe 13, the pipe body, branch pipe 134, first connector 131, second connector 132, and third connector 133 are constructed as an integral molded part. The integral molded construction of the pipe body, branch pipe 134, first connector 131, second connector 132, and third connector 133 of the connecting pipe 13 improves the integration and structural strength of the connecting pipe 13, allowing for better connection between the connecting pipe 13 and the valve seat 11 and the heat exchanger 14. The integral molded construction of the connecting pipe 13 also reduces the assembly procedure and complexity between the connecting pipe 13 and the valve seat 11, and improves the sealing performance of the connecting pipe 13 at various locations.

[0051] The thermal management system according to the present invention is briefly described below.

[0052] The thermal management system according to the present invention includes the valve assembly 1 as described in any of the above embodiments. Because the thermal management system according to the present invention is equipped with the valve assembly 1 described in any of the above embodiments, the valve seat 11 of the thermal management system according to the present invention does not need to form complex flow channels inside the valve seat 11 using brazing. The valve assembly 1 of the present invention is more convenient to assemble and maintain, and has lower production and manufacturing difficulty. This reduces the production cost of the thermal management system, and improves the sealing performance and reliability of the thermal management system.

[0053] The following is a brief description of a specific embodiment of the valve assembly 1 according to the present invention.

[0054] The valve assembly 1 for a thermal management system according to the present invention includes a valve seat 11, a valve body 12, a connecting pipe 13, and a heat exchanger 14. The valve seat 11 has a valve mounting cavity 114, and a connecting channel communicating with the valve mounting cavity 114 is formed inside the valve seat 11. At least a portion of the valve body 12 is housed within the valve mounting cavity 114 and is adapted to control the flow of medium within the connecting channel. There can be multiple valve mounting cavities 114, with each valve body 12 housed within a corresponding valve mounting cavity 114. Any two or more valve mounting cavities 114 can communicate with each other, or each valve mounting cavity 114 can be isolated from each other.

[0055] The heat exchanger 14 has a heat exchange interface 141, and the valve seat 11 has an interface that communicates with the connection channel. One end of the connecting pipe 13 is connected to the interface. The interface is configured to be multiple and includes a first interface 111 and a second interface 112. The connecting pipe 13 is configured to be multiple, with one end of each connecting pipe 13 connected to the first interface 111, and the other end of each connecting pipe 13 connected to at least one of the second interface 112 and the heat exchange interface 141.

[0056] The present invention forms one or more valve mounting cavities 114 on the valve seat 11, and a connecting channel communicating with the valve mounting cavity 114 is formed inside the valve seat 11. At least a portion of the valve body 12 is housed in the valve mounting cavity 114. This invention changes the situation in the related art where the flow channel is formed inside the valve seat 11 by die casting. The present invention realizes the communication between the valve seat 11 and the heat exchanger 14 and the communication between different interfaces on the valve seat 11 through the interface formed on the valve seat 11 that communicates with the connecting channel and the connecting pipe 13, thereby reducing the brazing process and making assembly and maintenance more convenient.

[0057] According to one embodiment of the present invention, at least two connecting pipes 13 are constructed as a single integral part.

[0058] At least two connecting pipes 13 are constructed as a single molded part, which can improve the integration of valve assembly 1, reduce the number of parts, and reduce the assembly difficulty between connecting pipe 13 and valve seat 11 and heat exchanger 14. The connection between connecting pipe 13 and valve block and heat exchanger 14 is more convenient, and the development and mold opening costs of a single connecting pipe 13 are further reduced. According to one embodiment of the present invention, the connecting pipe 13 is constructed as a single molded part with at least one of valve seat 11 and heat exchanger 14.

[0059] According to one embodiment of the present invention, the connecting pipe 13 and at least one of the valve seat 11 and heat exchanger 14 are integrally formed. Integrating the connecting pipe 13 and at least one of the valve seat 11 and heat exchanger 14 into an integral form results in a higher degree of integration of the valve assembly 1 for thermal management, fewer parts in the valve assembly 1, and further reduction in cost.

[0060] According to one embodiment of the present invention, the valve seat 11 has a first surface and a second surface, the first surface and the second surface are respectively disposed on both sides in the thickness direction of the valve seat 11, the valve mounting cavity 114 has an opening formed on the first surface, and a first interface 111 and a second interface 112 are disposed on the second surface.

[0061] The valve mounting cavity 114 has an open opening on its first surface. The valve body 12 is housed within the valve mounting cavity 114 through this opening, making the assembly of the valve body 12 more convenient and the machining of the valve mounting cavity 114 easier. The connection channel does not need to be overly complex. The fit between the valve seat 11 and the connecting pipe 13 replaces the method used in related technologies where a groove is formed in the valve seat 11 body using a die-casting process. This makes the assembly of the valve assembly 1 and the valve body 12 simpler and more convenient. A first interface 111 and a second interface 112 are provided on the second surface. The heat exchanger 14 is connected to the valve seat 11 via the connecting pipe 13, simplifying assembly and saving space.

[0062] According to one embodiment of the present invention, two heat exchangers 14 are configured, the two heat exchangers 14 are arranged at intervals, and the heat exchange interface 141 is disposed between the two heat exchangers 14 and is open to each other.

[0063] Two heat exchangers 14 are spaced apart, with heat exchange ports 141 located between them and open to each other. This arrangement of the heat exchangers 14 and connecting pipes 13 saves space and makes maintenance and replacement of the heat exchangers 14 more convenient. Furthermore, since the connecting pipes 13 are located between the two heat exchangers 14, they are not exposed to the outside, and the heat exchangers 14 effectively protect the connecting pipes 13.

[0064] According to one embodiment of the present invention, the valve seat 11 has a third surface on the side, and the interface further includes a third interface 113, which is disposed on the third surface and communicates with the connection channel.

[0065] The third interface 113 can be connected to different heat exchange pipelines and heat exchange units to meet different heat exchange conditions. The third interface 113 is located on the third surface of the valve seat 11 and is connected to the connection channel. The medium flows between the valve body 12 and the valve seat 11. When the third interface 113 is connected to different heat exchange pipelines and heat exchange units, the medium can easily flow in different heat exchange pipelines and heat exchange units to cope with different heat exchange conditions.
