[0041] In order to make the purpose, technical solutions and advantages of the technical solutions of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings of the embodiments of the present disclosure. The same reference signs in the drawings represent the same components.

[0043] See below Figures 1 to 13 The embodiments of this disclosure are described in detail.

[0044] Figure 1 and 2 External schematic diagrams of the fluid distribution assembly according to this disclosure in different orientations are shown. Figures 3 to 9 Different cross-sectional views of a fluid distribution assembly are shown, illustrating cross-sections of different portions of the assembly to illustrate various flow channels or passages. The fluid distribution assembly can be used in a vehicle thermal management system, for example, mounted on a flow channel plate within the system, such as a refrigerant flow channel plate, and communicates with components within the system, such as water condensers, evaporator condensers, and internal heat exchangers. Fluids such as refrigerant can be distributed to components within the vehicle thermal management system via the fluid distribution assembly. Of course, the fluid distribution assembly of this disclosure can also be applied to a coolant flow channel plate for distributing fluids such as coolant.

[0045] like Figure 1 As shown, the fluid distribution assembly includes a valve block 1, a first valve 7, and a second valve 8. Figure 5 As shown, valve block 1 has a first interface 10, a first chamber 101, and a second chamber 102. The first chamber 101 and the second chamber 102 are in fluid communication, for example, through... Figure 5 The vertical channels within the valve block 1 shown are in fluid communication. A first valve 7 is installed in the first chamber 101, and a second valve 8 is installed in the second chamber 102. Figure 5 As shown, the fluid distribution assembly also includes a valve seat 9, which is installed inside the valve block 1 and abuts against the second valve 8. The second valve 8 is in fluid communication with the first interface 10 through the valve seat 9.

[0046] For example, the first chamber 101 can form a part of a valve chamber of the first valve 7, a valve port of the first valve 7 can be formed at a bottom of the first chamber 101, for example, on a bottom wall of a recess formed at an end of the valve block 1. For example, the second chamber 102 can form a part of a valve chamber of the second valve 8. Alternatively, at least a part of the first valve 7 can be arranged in the first chamber 101, and at least a part of the second valve 8 can be arranged in the second chamber 102.

[0047] For example, the first valve 7 can be a multi-port valve, such as a multi-port valve having at least five valve ports. In particular, the first valve 7 can be a five-port valve having a first valve port V1 to a fifth valve port V5, as shown in Figure 5 The present disclosure does not limit the number of valve ports of the multi-port valve.

[0048] For example, the second valve 8 is in fluid communication with the first interface 10 in a throttling manner, i.e., the second valve 8 can have a throttling mode in which fluid flows through the second valve 8 in a throttling manner. For example, the second valve 8 can be a three-port throttling ball valve or a three-port expansion ball valve. The present disclosure does not limit the number of valve ports of the second valve 8.

[0049] In addition to the above-mentioned throttling mode, the second valve 8 can also have a full-open mode and a full-closed mode. In the full-open mode, fluid can flow through the second valve 8 substantially without pressure loss. In the full-closed mode, fluid cannot flow through the second valve 8. The switching between the above-mentioned three modes is achieved by the rotation of a valve ball of the second valve 8 as described below.

[0050] The above-mentioned fluid distribution assembly integrates the first valve and the second valve together, in particular, integrates the five-port valve and the throttling ball valve together, and has high integration, flexible design and simple structure, thereby reducing the cost of the vehicle thermal management system and simplifying the control strategy of the vehicle thermal management system.

[0051] Referring again to Figure 1 and 5 , the valve block 1 has a first interface face 4, a first mounting face 2 and a second mounting face 3, the first interface 10 is arranged at the first interface face 4, the first valve 7 is mounted at the first mounting face 2, and the second valve 8 is mounted at the second mounting face 3. For example, the first mounting face 2 and the second mounting face 3 can be located at two ends of the valve block 1, as shown in Figure 5The valve block 1 has a recess (e.g. recessed towards the center of the valve block or vertically downward recessed) at the first mounting face 2 to form a first chamber 101. The valve block 1 has a recess (e.g. recessed towards the center of the valve block or vertically upward recessed) at the second mounting face 3 to form a second chamber 102. Such configuration not only makes the structure of the fluid distribution assembly compact, but also does not hinder the engagement with the flow channel plate, for example, the side surface for engagement with the flow channel plate, i.e. the first interface face 4 described above, can be left. Further, such configuration makes the installation, disassembly and maintenance of the valve more simple and convenient.

[0052] Referring to Figure 5 , the valve seat 9 has an internal passage 90 through which the second valve 8 communicates with the first interface 10, the internal passage 90 is arranged to bend the fluid. The meaning of "bend the fluid" is that the flow direction of the fluid changes by a non-zero angle, for example Figure 3 and 5 90 degrees shown in, i.e. from the vertically downward direction to the horizontally left direction.

[0053] As shown in Figure 3 and 5 , the valve seat 9 has a first opening 91 arranged in the axial direction and a second opening 92 arranged in the radial direction, which define the internal passage 90 described above. The valve seat 9 can have a generally cylindrical body shape, for example, has a cylindrical upper end and a cylindrical lower end, and a relatively small intermediate portion therebetween. For example, in the axial direction (i.e. vertical direction) of the valve seat 9, the valve seat 9 has the first opening 91, for example, at its upper end close to the second valve 8, and in the radial direction of the valve seat 9, the valve seat 9 has the second opening 92, for example, at its intermediate portion. The arrangement of such differently oriented openings achieves the bending of the fluid, and the structure is simple and compact.

[0054] As shown in Figure 1 , the valve block 1 also has a second interface face 5 on which a second interface 12 is arranged, the second valve 8 is in fluid communication with the second interface 12. In this way, the three valve ports of the second valve 8, for example, a three-way throttling ball valve, can be in fluid communication with the first valve 7, the first interface 10 and the second interface 12, respectively. For example, the second interface 12 can be in fluid communication with elements of the vehicle thermal management system, for example, through a pipeline.

[0055] Considering that the first mounting face 2 and the second mounting face 3 are located at both ends of the valve block 1, the first interface face 4 and the second interface face 5 can be adjacent to each other. In this way, a compact structure can be achieved, and the installation of the fluid distribution assembly with the flow channel plate will not be affected. Of course, the first interface face 4 and the second interface face 5 can not be adjacent, for example, they can be opposite to each other.

[0056] As shown in Figure 1 , the valve block 1 has an extension axis A1 and can be a block structure extending along the extension axis A1. As shown in Figures 4 to 9 , the valve block 1 has a plurality of first channels 13, 14, 15, 41, 42 extending along the extension axis A1, which are formed at different positions of the valve block 1 and communicate with different valve ports of the first valve 7, which can be seen from the figures. For example, the first valve 7, such as a five-way valve, can have multiple working modes, in different working modes, the first valve 7 selectively communicates at least two of the above-mentioned first channels 13, 14, 15, 41, 42, in other words, at least two valve ports. The second valve 8 is in fluid communication with the first valve 7 through the corresponding first channel. Specifically, as shown in Figure 5 , the second valve 8 is in fluid communication with the first valve 7 through the first channel 13. One end (such as the upper end in Figure 5 ) of the first channel 13 communicates with the first chamber 101, and can also be said to communicate with the first valve port V1 of the first valve 7, and the other end (such as the lower end in Figure 5 ) communicates with the second chamber 102. For example, these first channels 13, 14, 15, 41, 42 are integrally formed with the valve block 1.

[0057] As shown in Figures 4 to 9 , the valve block 1 has second channels 16, 17, 18, 43 extending along a first direction S1 transverse to the extension axis A1, which are formed at different positions of the valve block 1, which can be seen from Figure 5 , 6 , 7 and 9. The second valve 8 is in fluid communication with the first interface 10 through the corresponding second channel. Specifically, as shown in Figure 5 , the second valve 8 is in fluid communication with the first interface 10 through the second channel 16. One end (such as the right end in Figure 5 ) of the second channel 16 communicates with the second chamber 102, and the other end (such as the left end in Figure 5 ) communicates with the first interface 10. For example, these second channels 16, 17, 18, 43 are integrally formed with the valve block 1.

[0058] As shown in Figures 7 to 8 , the valve block 1 has a third channel 19 extending along a second direction S2 transverse to the extension axis A1 and the first direction S1, and the second valve 8 is in fluid communication with the second interface 12 through the third channel 19. The second direction S2 is perpendicular to the plane formed by the extension axis A1 and the first direction S1. As shown in Figure 8 , one end of the third channel 19 communicates with the second chamber 102, and the other end (such as the left end in Figure 8 ) communicates with the second interface 12.

[0059] As shown in Figure 2As shown, the valve block 1 also has a third interface face 6 opposite the first interface face 4, and the third interface face 6 is provided with third interfaces 23, 24. For example, the valve block 1 can be a cuboid with four side faces in general, and the third interface face 6 is adjacent to the second interface face 5, and the second interface face 5 is adjacent to the first interface face 4.

[0060] As shown in Figure 5 and 9 , the valve block 1 has fourth channels 25, 26 extending in a third direction S3 transverse to the extension axis A1 and opposite the first direction S1, and the valve ports of the first valve 7 are in fluid communication with the corresponding third interfaces through the corresponding first channels and the corresponding fourth channels. For example, the first valve port V1 of the first valve 7 is in fluid communication with the third interface 24 through the first channel 13 and the fourth channel 25 that are in communication with each other, as shown in Figure 5 . For example, the fourth valve port V4 of the first valve 7 is in fluid communication with the third interface 23 through the first channel 42 and the fourth channel 26 that are in communication with each other, as shown in Figure 9 . The second valve 8 is also mounted on the third interface face 6.

[0061] As shown in Figure 1 , the first interface face 4 is also provided with fourth interfaces 20, 21, 22, and the valve ports of the first valve 7 are in fluid communication with the corresponding fourth interfaces through the corresponding first channels and the corresponding second channels. For example, the second valve port V2 of the first valve 7 is in fluid communication with the fourth interface 20 through the first channel 14 and the second channel 17 that are in communication with each other, as shown in Figure 6 . For example, the fifth valve port V5 of the first valve 7 is in fluid communication with the fourth interface 21 through the first channel 41 and the second channel 18 that are in communication with each other, as shown in Figure 7 . For example, the third valve port V3 of the first valve 7 is in fluid communication with the fourth interface 22 through the first channel 15 and the second channel 43 that are in communication with each other.

[0062] By providing channels extending in different directions in the valve block, the communication of the first valve and the second valve can be achieved, and the communication of the first valve and / or the second valve with the elements of the vehicle thermal management system or with the flow channel plate can also be achieved, so that different vehicle thermal management modes can be assisted to be achieved, and the overall structure is simple and compact.

[0063] As shown in Figure 3 , 5As shown in Figure 10, the valve seat 9 has a cylindrical shape extending along the extending axis A1, and the circumferential sidewall 27 of the valve seat 9 has a plurality of through holes 28. For example, the circumferential sidewall 27 has three through holes 28. The through holes 28 form the second opening 92 described above. For example, a plurality of through holes 28 are formed on the circumferential sidewall at the middle portion between the upper end and the lower end of the cylinder. For example, the plurality of through holes 28 are evenly distributed on the circumferential sidewall 27 of the valve seat 9. The through holes 28 form the second opening 92 of the valve seat 9 described above, which is opened radially.

[0064] By providing multiple through holes, a more flexible installation method can be provided, as it is not necessary to strictly align the through holes with the second channel 16. Regardless of the installation position, the valve seat of this disclosure allows unobstructed flow of fluid to the second channel 16.

[0065] like Figure 3 and 5 As shown, the valve seat 9 is housed in the second chamber 102 of the valve block 1, and the inner wall of the second chamber 102 forms an annular channel 36 of the internal passage 90 with the valve seat 9. For example, the second chamber 102 may have a cylindrical shape, so that its inner wall can form an annular channel 36 with the valve seat 9. For example, a seal such as an O-ring is provided between the valve seat 9 and the inner wall of the second chamber 102, for example, a seal is provided at both the upper and lower ends of the cylinder. This allows the fluid to flow more smoothly into the second passage 16 and then out through the first port 10.

[0066] like Figures 10 to 13 As shown, the second valve 8 includes a valve ball 29, a valve ball seat 30, a valve cover 31, and an actuator 32. The valve ball 29 and the valve seat 9 respectively abut against both ends of the valve ball seat 30. For example, the upper end of the valve seat 9 is provided with a groove for accommodating the valve ball seat 30. For example, a sealing element such as an O-ring is provided between the valve ball seat 30 and the valve seat 9. The ball wall of the valve ball 29 has an expansion groove 33, such as... Figure 12 As shown. The actuator 32 drives the valve ball 29 to rotate about a rotation axis A2 transverse to the extending axis A1, and the direction of rotation is as follows. Figure 10 As indicated by the arrow, the expansion groove 33 and the valve ball seat 30 form different fluid flow sections. The extending axis A1, for example, follows along... Figure 1 The vertical direction in the middle, while the rotation axis A2, for example, along the vertical direction in the middle. Figure 1The extension axis A1 is perpendicular to the rotation axis A2, i.e. in the horizontal direction in the drawing. As mentioned above, the actuator 32 is mounted to the third interface surface 6. The throttling function is achieved by changing the fluid flow cross section by rotation of the valve ball 29 around the rotation axis A2. The rotation of the valve ball 29 can also achieve a full open or full closed mode. The fluid flow cross section is formed at the contact between the expansion groove 33 and the valve ball seat 30, in particular by the cross sectional area of the expansion groove 33 at the contact between the expansion groove 33 and the valve ball seat 30 perpendicular to the extension axis A1.

[0067] As shown in Fig. 3, the groove depth of the expansion groove 33 in the rotation direction of the valve ball 29 is gradually changed. For example, the groove depth can gradually decrease in the rotation direction of the valve ball 29 as shown in Fig. 3, so that the fluid flow cross section can gradually increase, or the groove depth can gradually increase in the direction opposite to the rotation direction of the valve ball 29, so that the fluid flow cross section can gradually decrease. In this way, the regulation of the fluid flow through the second valve is achieved. Figure 12 Figure 10 As shown in Fig. 3, the groove depth of the expansion groove 33 in the rotation direction of the valve ball 29 is gradually changed. For example, the groove depth can gradually decrease in the rotation direction of the valve ball 29 as shown in Fig. 3, so that the fluid flow cross section can gradually increase, or the groove depth can gradually increase in the direction opposite to the rotation direction of the valve ball 29, so that the fluid flow cross section can gradually decrease. In this way, the regulation of the fluid flow through the second valve is achieved.

[0068] As shown in Fig. 3, the groove depth of the expansion groove 33 in the rotation direction of the valve ball 29 is gradually changed. For example, the groove depth can gradually decrease in the rotation direction of the valve ball 29 as shown in Fig. 3, so that the fluid flow cross section can gradually increase, or the groove depth can gradually increase in the direction opposite to the rotation direction of the valve ball 29, so that the fluid flow cross section can gradually decrease. In this way, the regulation of the fluid flow through the second valve is achieved. Figure 10 Figure 7 As shown in Fig. 3, the groove depth of the expansion groove 33 in the rotation direction of the valve ball 29 is gradually changed. For example, the groove depth can gradually decrease in the rotation direction of the valve ball 29 as shown in Fig. 3, so that the fluid flow cross section can gradually increase, or the groove depth can gradually increase in the direction opposite to the rotation direction of the valve ball 29, so that the fluid flow cross section can gradually decrease. In this way, the regulation of the fluid flow through the second valve is achieved.

[0069] As shown in Fig. 3, the groove depth of the expansion groove 33 in the rotation direction of the valve ball 29 is gradually changed. For example, the groove depth can gradually decrease in the rotation direction of the valve ball 29 as shown in Fig. 3, so that the fluid flow cross section can gradually increase, or the groove depth can gradually increase in the direction opposite to the rotation direction of the valve ball 29, so that the fluid flow cross section can gradually decrease. In this way, the regulation of the fluid flow through the second valve is achieved.
