Detailed Implementation

[0023] The embodiments of this utility model 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 this utility model, and should not be construed as limiting this utility model.

[0024] The following is for reference. Figures 1-7 The valve island structure 100 according to an embodiment of the present utility model is described.

[0025] like Figure 2 , Figures 4-6 As shown, the valve island structure 100 according to an embodiment of the present invention has a first valve interface 11, a second valve interface 12, and a first interface 21, along the first direction (i.e., Figures 4-6(As shown in the X direction), the distance between the centerline of the first valve interface 11 and the centerline of the second valve interface 12 is greater than the distance between the centerline of the first interface 21 and the centerline of the second valve interface 12.

[0026] The valve island structure 100 includes a first valve interface 11, a second valve interface 12, and a first interface 21. As some embodiments of this application, the first valve interface 11 can be configured as a high-pressure valve interface for connecting a high-pressure valve, the second valve interface 12 can be configured as a low-pressure valve interface for connecting a low-pressure valve, and the first interface 21 can be used to connect other components (such as, but not limited to, a plate heat exchanger 500).

[0027] As some embodiments of this application, the flow path unit 200 includes a valve island structure 100, a plurality of valve bodies (e.g., but not limited to high-pressure valves, low-pressure valves, etc.) and a plate heat exchanger 500.

[0028] Along the first direction (i.e.) Figures 4-6 (As shown in the X direction), the distance between the centerline of the first valve interface 11 and the centerline of the second valve interface 12 is greater than the distance between the centerline of the first interface 21 and the centerline of the second valve interface 12. This is one of the embodiments of this application, such as... Figures 4-6 As shown, along the first direction (i.e. Figures 4-6 (As shown in the X direction), the centerline of the first interface 21 is located between the centerline of the first valve interface 11 and the centerline of the second valve interface 12. In other words, along the first direction (i.e. Figures 4-6 (As shown in the X direction), the center lines of the second valve interface 12, the first interface 21, and the first valve interface 11 are arranged alternately.

[0029] It should be noted that the first valve port 11 and the second valve port 12 of the valve island structure 100 are respectively connected to the high-pressure valve and the low-pressure valve. Sufficient installation space needs to be reserved between the first valve port 11 and the second valve port 12. This ensures that after installing one of the high-pressure valves or low-pressure valves in the valve island structure 100, the operator or operating tools are less likely to interfere with the already installed valve body when installing the other high-pressure valve or low-pressure valve, facilitating the installation of the other high-pressure valve or low-pressure valve. Compared to traditional structures, the valve island structure 100 of this application significantly increases the distance between the first valve port 11 and the second valve port 12 by making the distance between the center lines of the first valve port 11 and the second valve port 12 greater than the distance between the center lines of the first port 21 and the second valve port 12. This facilitates the installation of the high-pressure valve and the low-pressure valve, while not increasing the volume of the valve island structure 100, thus improving the compactness of the components in the flow path unit 200.

[0030] Therefore, by making the distance between the center line of the first valve interface 11 and the center line of the second valve interface 12 greater than the distance between the center line of the first interface 21 and the center line of the second valve interface 12, it is convenient to install the other valve body that matches the first valve interface 11 and the second valve interface 12 after installing the valve body that matches one of the first valve interface 11 and the second valve interface 12. This reduces the assembly difficulty and improves the assembly efficiency. At the same time, it does not require increasing the volume of the valve island structure 100, which is beneficial to the miniaturization design of the valve island structure 100.

[0031] In some embodiments of this utility model, the first valve interface 11 and the first interface 21 have different orientations.

[0032] As some embodiments of this application, along the second direction (i.e. Figure 4 and Figure 6 (as shown in the Y direction), the first valve port 11 is open to one side, along the third direction (i.e. Figure 3 (As shown in the Z direction), the first interface 21 is open to one side. As some embodiments of this application, the centerline of the first valve interface 11 is perpendicular to the centerline of the first interface 21.

[0033] As some embodiments of this application, the first direction (i.e. Figures 4-6 The X direction shown), the second direction (i.e. Figure 4 and Figure 6 The Y-direction shown), and the third direction (i.e. Figure 3 The Z directions shown are mutually perpendicular, i.e., the first direction (i.e. Figures 4-6 The X-direction shown), the orientation of the first valve port 11, and the orientation of the first port 21 are perpendicular to each other.

[0034] As some embodiments of this application, a third party (i.e.) Figure 3 The Z-direction shown is constructed in the same direction as the thickness direction of the valve island structure 100.

[0035] This arrangement allows for a reasonable orientation of the first valve interface 11 and the first interface 21, facilitating the connection between the valve island structure 100 and the high-pressure valve and plate heat exchanger 500, reducing the risk of interference during installation, making reasonable use of the space in all directions of the valve island structure 100, and improving the integration and compactness of the flow path unit 200.

[0036] In some embodiments of this utility model, such as Figures 4-6 As shown, the first valve port 11 and the second valve port 12 have the same orientation.

[0037] As some embodiments of this application, along the second direction (i.e. Figure 4 and Figure 6 (as shown in the Y direction), the first valve port 11 is open to one side, along the second direction (i.e. Figure 4 and Figure 6 (As shown in the Y direction), the second valve port 12 is open to one side. And, along the second direction (i.e., Figure 4 and Figure 6 (As shown in the Y direction), the first valve port 11 and the second valve port 12 are located on the same side of the valve island structure 100 and open towards the same side. As some embodiments of this application, the centerline of the first valve port 11 is parallel to the centerline of the second valve port 12.

[0038] This arrangement allows for a reasonable orientation of the first valve interface 11 and the second valve interface 12, facilitating the connection between the valve island structure 100 and the high-pressure valve and the low-pressure valve, and also improving the integration and compactness of the flow path unit 200.

[0039] In some embodiments of this utility model, such as Figure 3 and Figure 5 As shown, the valve island structure 100 has a first flow channel 13, a second flow channel 14, and a third flow channel 23. The first flow channel 13 is connected to the first valve interface 11, the third flow channel 23 is connected to the first interface 21, and the second flow channel 14 is connected between the first flow channel 13 and the third flow channel 23.

[0040] The first flow channel 13 is connected to the first valve interface 11. As some embodiments of this application, the refrigerant can flow in the first flow channel 13 and through the first valve interface 11 between the valve island structure 100 and other components (such as, but not limited to, high-pressure valves).

[0041] The third flow channel 23 is connected to the first interface 21. As some embodiments of this application, the refrigerant can flow in the third flow channel 23 and through the first interface 21 between the valve island structure 100 and other components (such as, but not limited to, the plate heat exchanger 500).

[0042] The second flow channel 14 is connected between the first flow channel 13 and the third flow channel 23. As some embodiments of this application, the first flow channel 13, the second flow channel 14, and the third flow channel 23 are arranged in sequence and connected, and the refrigerant can flow between the first flow channel 13, the second flow channel 14, and the third flow channel 23.

[0043] By connecting the first flow channel 13 to the first valve interface 11, the third flow channel 23 to the first interface 21, and the second flow channel 14 between the first flow channel 13 and the third flow channel 23, the first valve interface 11 can be connected to the first interface 21, so that the refrigerant can flow between the high-pressure valve and the plate heat exchanger 500.

[0044] In some embodiments of this utility model, the flow cross-sectional area of ​​the second flow channel 14 is larger than the flow cross-sectional area of ​​the third flow channel 23.

[0045] This configuration allows for the miniaturization of the third flow channel 23, resulting in a smaller volume. This not only facilitates the installation of the third flow channel 23 but also enables the miniaturization of the valve island structure 100. Furthermore, it allows for localized velocity changes in the refrigerant flow between the second flow channel 14 and the third flow channel 23, ensuring smooth refrigerant flow.

[0046] In some embodiments of this utility model, such as Figure 5 As shown, at least a portion of the cross-section of the first flow channel 13 is circular, and at least a portion of the cross-section of the third flow channel 23 is circular.

[0047] At least a portion of the cross-section of the first flow channel 13 is circular. As some embodiments of this application, a portion of the cross-section of the first flow channel 13 is circular, or all of the cross-sections of the first flow channel 13 are circular.

[0048] At least a portion of the cross-section of the third flow channel 23 is circular. As some embodiments of this application, a portion of the cross-section of the third flow channel 23 is circular, or the entire cross-section of the third flow channel 23 is circular.

[0049] This design allows the refrigerant to flow smoothly in the first flow channel 13 and the third flow channel 23, making it less prone to eddies or turbulence and reducing flow resistance. This is beneficial for improving the refrigerant delivery efficiency. At the same time, the circular cross-section is easy to process, reducing the manufacturing cost of the valve island structure 100.

[0050] In some embodiments of this utility model, such as Figure 5 As shown, the second flow channel 14 includes: a first sub-flow channel 141 and a second sub-flow channel 142. The first sub-flow channel 141 is connected between the first flow channel 13 and the second sub-flow channel 142. The second sub-flow channel 142 is connected to the third flow channel 23. At least a portion of the inner wall surface of the first sub-flow channel 141 is constructed as a first arc surface 1411. The central axis of the first arc surface 1411 is collinear with the central axis of the first flow channel 13.

[0051] The first sub-channel 141 is connected between the first channel 13 and the second sub-channel 142. As some embodiments of this application, the first channel 13, the first sub-channel 141, and the second sub-channel 142 are arranged and connected in sequence, and the refrigerant can flow between the first channel 13, the first sub-channel 141, and the second sub-channel 142.

[0052] The second sub-channel 142 is connected to the third channel 23. As some embodiments of this application, the first channel 13, the first sub-channel 141, the second sub-channel 142, and the third channel 23 are arranged and connected in sequence, and the refrigerant can flow between the first channel 13, the first sub-channel 141, the second sub-channel 142, and the third channel 23.

[0053] At least a portion of the inner wall surface of the first sub-channel 141 is constructed as a first arc surface 1411. As some embodiments of this application, a portion of the inner wall surface of the first sub-channel 141 is constructed as a first arc surface 1411, or all the inner wall surfaces of the first sub-channel 141 are constructed as first arc surfaces 1411.

[0054] The central axis of the first arc surface 1411 is collinear with the central axis of the first flow channel 13. In some embodiments of this application, a portion of the inner wall surface of the first sub-flow channel 141 is constructed as the first arc surface 1411, and the central axis of the first arc surface 1411 is collinear with the central axis of the first flow channel 13. In some embodiments of this application, the curvature of the first arc surface 1411 is the same as the curvature of the inner wall surface of the first flow channel 13. In some embodiments of this application, the first arc surface 1411 and the inner wall surface of the first flow channel 13 can be formed using the same processing step.

[0055] This configuration allows the first sub-channel 141 to be adapted to the first channel 13, thereby reducing the obstruction of internal fluid (refrigerant) flow caused by the change in cross-section. This ensures that the refrigerant flows smoothly in the first sub-channel 141 and the first channel 13, making it less prone to eddies or turbulence and reducing flow resistance. This is beneficial for improving the refrigerant delivery efficiency. At the same time, it facilitates the processing of the first sub-channel 141 and reduces the manufacturing cost of the valve island structure 100.

[0056] In some embodiments of this utility model, such as Figure 5 As shown, the second flow channel 14 includes a first sub-flow channel 141 and a second sub-flow channel 142. The first sub-flow channel 141 is connected between the first flow channel 13 and the second sub-flow channel 142. The second sub-flow channel 142 is connected to the third flow channel 23. At least a portion of the inner wall surface of the second sub-flow channel 142 is constructed as a second arc surface 1421. The central axis of the second arc surface 1421 is collinear with the central axis of the third flow channel 23.

[0057] The first sub-channel 141 is connected between the first channel 13 and the second sub-channel 142. As some embodiments of this application, the first channel 13, the first sub-channel 141, and the second sub-channel 142 are arranged and connected in sequence, and the refrigerant can flow between the first channel 13, the first sub-channel 141, and the second sub-channel 142.

[0058] The second sub-channel 142 is connected to the third channel 23. As some embodiments of this application, the first channel 13, the first sub-channel 141, the second sub-channel 142, and the third channel 23 are arranged and connected in sequence, and the refrigerant can flow between the first channel 13, the first sub-channel 141, the second sub-channel 142, and the third channel 23.

[0059] At least a portion of the inner wall surface of the second sub-channel 142 is constructed as a second arc surface 1421. As some embodiments of this application, a portion of the inner wall surface of the second sub-channel 142 is constructed as a second arc surface 1421, or all the inner wall surfaces of the second sub-channel 142 are constructed as second arc surfaces 1421.

[0060] The central axis of the second arc surface 1421 is collinear with the central axis of the third flow channel 23. In some embodiments of this application, a portion of the inner wall surface of the second sub-flow channel 142 is constructed as the second arc surface 1421, and the central axis of the second arc surface 1421 is collinear with the central axis of the third flow channel 23. In some embodiments of this application, the curvature of the second arc surface 1421 is the same as the curvature of the inner wall surface of the third flow channel 23. In some embodiments of this application, the inner wall surfaces of the second arc surface 1421 and the third flow channel 23 can be formed using the same processing step.

[0061] This configuration allows the second sub-channel 142 to be adapted to the third channel 23, reducing the obstruction of internal fluid (refrigerant) flow caused by the variable cross-section. This ensures smooth refrigerant flow in the second sub-channel 142 and the third channel 23, minimizing the generation of eddies or turbulence and reducing flow resistance. This improves refrigerant delivery efficiency and facilitates the processing of the second sub-channel 142, reducing the manufacturing cost of the valve island structure 100.

[0062] In some embodiments of this utility model, such as Figures 1-7 As shown, the valve island structure 100 includes: a flow channel plate 1 and a base plate 2. The flow channel plate 1 is connected to the base plate 2. The flow channel plate 1 forms a first valve interface 11, a second valve interface 12, a first flow channel 13, and a second flow channel 14. The base plate 2 forms a first interface 21 and a third flow channel 23.

[0063] In this embodiment, the flow channel plate 1 is connected to the base plate 2. As some embodiments of this application, along the thickness direction of the flow channel plate 1 and the base plate 2 (i.e., the aforementioned third direction), Figure 3 (As shown in the Z direction), the flow channel plate 1 and the base plate 2 are arranged and connected in sequence. As some embodiments of this application, the flow channel plate 1 and the base plate 2 can be welded together or integrally formed. The flow channel plate 1 has a first valve port 11, a second valve port 12, a first flow channel 13, and a second flow channel 14. As some embodiments of this application, the flow channel plate 1 has a thickness direction (i.e., the aforementioned third direction). Figure 3 A first flow channel 13 and a second flow channel 14 are formed on one side of the flow channel plate 1 (shown in the Z direction). A first valve interface 11 communicating with the first flow channel 13 is formed on the flow channel plate 1, and a second valve interface 12 is formed on the flow channel plate 1.

[0064] The base plate 2 has a first interface 21 and a third flow channel 23. As some embodiments of this application, the thickness direction of the base plate 2 (i.e., the aforementioned third direction) is... Figure 3 A third flow channel 23 is formed on one side of the Z direction (as shown), and a first interface 21 communicating with the third flow channel 23 is formed on the bottom plate 2.

[0065] This arrangement allows the first valve port 11, the second valve port 12, and the first port 21 to be located along the thickness direction of the flow channel plate 1 and the bottom plate 2 of the valve island structure 100 (i.e., the aforementioned third direction). Figure 3 The two sides (in the Z direction shown) reduce the risk of interference between the valve body and the plate heat exchanger 500 during assembly. Furthermore, the valve island structure 100 can integrate the first valve interface 11, the second valve interface 12, and the first interface 21, thereby improving the integration compactness of the flow path unit 200.

[0066] In some embodiments of this utility model, such as Figure 7 As shown, the base plate 2 also has a second interface 22. The center line of the second interface 22 is parallel to and coplanar with the center line of the first interface 21. Both the first interface 21 and the second interface 22 are constructed as interfaces of a plate heat exchanger 500.

[0067] Wherein, the center line of the second interface 22 is parallel and coplanar with the center line of the first interface 21. As some embodiments of this application, the center lines of the second interface 22 and the first interface 21 are both perpendicular to the plane of the base plate 2.

[0068] Both the first interface 21 and the second interface 22 are configured as interfaces of the plate heat exchanger 500. In some embodiments of this application, the first interface 21 can be assembled with the inlet of the heat exchange channel of the plate heat exchanger 500, and the second interface 22 can be assembled with the outlet of the heat exchange channel of the plate heat exchanger 500. Alternatively, the first interface 21 can be assembled with the outlet of the heat exchange channel of the plate heat exchanger 500, and the second interface 22 can be assembled with the inlet of the heat exchange channel of the plate heat exchanger 500. In some embodiments of this application, the plate heat exchanger 500 can have two heat exchange channels, and both the first interface 21 and the second interface 22 are assembled with the same heat exchange channel.

[0069] By making the centerline of the second interface 22 parallel and coplanar with the centerline of the first interface 21, it is not only easier to process and form the second interface 22 and the first interface 21, but also to match the first interface 21 and the second interface 22 with the two ends of the heat exchange flow channel of the plate heat exchanger 500, thereby reducing the assembly difficulty of the valve island structure 100 and the plate heat exchanger 500.

[0070] As some embodiments of this application, the flow channel plate 1 is further formed with a fourth flow channel 15, and the bottom plate 2 is further formed with a fifth flow channel 24. The fifth flow channel 24 connects the fourth flow channel 15 and the second interface 22. The central axis of the fourth flow channel 15 is collinear with the central axis of the fifth flow channel 24, and the central axis of the fifth flow channel 24 is parallel to and coplanar with the central axis of the third flow channel 23.

[0071] The fifth flow channel 24 connects the fourth flow channel 15 and the second interface 22. As some embodiments of this application, the fourth flow channel 15, the fifth flow channel 24, and the second interface 22 are arranged and connected in sequence. The refrigerant can flow between the fourth flow channel 15 and the fifth flow channel 24 and flow between the valve island structure 100 and the plate heat exchanger 500 through the second interface 22.

[0072] As some embodiments of this application, the center lines of the third flow channel 23, the fourth flow channel 15, and the fifth flow channel 24 are all perpendicular to the plane of the base plate 2.

[0073] This configuration allows the refrigerant to flow smoothly between the valve island structure 100 and the plate heat exchanger 500, and also facilitates the fabrication of the third flow channel 23, the fourth flow channel 15, and the fifth flow channel 24.

[0074] In some embodiments of this utility model, at least a portion of the valve island structure 100 is made of stainless steel.

[0075] By using stainless steel for at least a portion of the valve island structure 100, the corrosion resistance of the valve island structure 100 is improved, preventing the valve island structure 100 from being corroded by the refrigerant and thus avoiding refrigerant leakage. In addition, stainless steel has good strength and rigidity, and can withstand the high pressure and potential hydraulic shock of the valve island structure 100 during operation, resulting in good reliability. Using stainless steel can reduce long-term maintenance costs and increase the service life of the valve island structure 100.
