[0036] In order to make the objectives, technical solutions and advantages of the present disclosure more clear and understandable, the present disclosure will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.
[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present disclosure belongs. The terms used in the specification of the present disclosure herein are only for the purpose of describing specific implementation manners and are not intended to limit the present disclosure.
[0038] The present disclosure provides a multi-way valve spool, a multi-way valve, a thermal management system and a new energy vehicle, which can realize the connection and disconnection of different pipelines of the thermal management system, simplify the thermal management system, save space and reduce costs.
[0039] The multi-way valve spool, multi-way valve, thermal management system and new energy vehicle of the present disclosure will be described in detail below with reference to the accompanying drawings. Without conflict, the features in the following embodiments and implementation manners can be combined with each other.
[0040] In an embodiment of the present disclosure, with reference to Figures 1 to 3As shown, a multi-way valve spool 100 is provided, which includes a flow channel main body 110 and a drive shaft 120. The flow channel main body 110 is cylindrical, including a flow channel cavity 111 and a plurality of partition plates 112 arranged in the flow channel cavity 111. The plurality of partition plates 112 divide the flow channel cavity 111 into a plurality of chambers 1110. The plurality of partition plates 112 include a plurality of first partition plates 1121 extending along the axial direction of the flow channel main body 110 and a plurality of second partition plates 1122 intersecting with the first partition plates 1121. In the circumferential direction of the flow channel cavity 111, the lengths of the plurality of chambers 1110 are integer multiples of the minimum length among the plurality of chambers 1110. In the axial direction of the flow channel cavity 111, the heights of the plurality of chambers 1110 are integer multiples of the minimum height among the plurality of chambers 1110. The drive shaft 120 is arranged at one end of the flow channel main body 110 and is connected to a transmission structure for driving the multi-way valve spool 100 to rotate.
[0041] The flow channel main body 110 extending in a cylindrical shape facilitates the arrangement of a plurality of flow channel cavities 111. The first partition plates 1121 extending along the axial direction of the flow channel main body 110 and the second partition plates 1122 extending along the axial direction of the flow channel main body can effectively utilize the space of the flow channel cavity 111 and fully divide it into a plurality of chambers 1110. Among the plurality of chambers 1110, one or more chambers have the minimum length in the circumferential direction of the flow channel cavity 111, and the lengths of the remaining chambers are integer multiples of this minimum value. Similarly, one or more chambers have the minimum height in the axial direction of the flow channel cavity 111, and the heights of the remaining chambers are integer multiples of this minimum value. In this way, a plurality of chambers 1110 can be regularly and orderly arranged in the circumferential and axial directions of the flow channel cavity 111, so as to set as many chambers as possible in the limited space of the flow channel cavity 111, improving the space utilization rate of the flow channel cavity 111.
[0042] The drive shaft 120 arranged at one end of the flow channel main body 110 does not affect the spatial arrangement of the chambers 1110 in the flow channel cavity 111.
[0043] In some embodiments, as Figure 1 shown, the second partition plates 1122 are perpendicular to the first partition plates 1121. The first partition plates 1121 extend along the axial direction of the flow channel main body 110, and the second partition plates 1122 being perpendicular to the first partition plates 1121 means that the second partition plates 1122 extend along the circumferential direction of the flow channel main body 110. In this way, the lengths and height directions of the plurality of chambers 1110 divided by the first partition plates 1121 and the second partition plates 1122 are parallel to the circumferential and axial directions of the flow channel main body 110, and further more chambers can be set in the limited accommodation cavity of the flow channel cavity 111. Moreover, when the first partition plates 1121 and the second partition plates 1122 meet the strength requirements and sealing requirements, they are designed to be as thin as possible, which can further improve the space utilization rate of the flow channel cavity 111.
[0044] In some embodiments, the circumferential length and axial height of the flow channel cavity 111 are integer multiples of the minimum length and minimum height of the chamber 1110 respectively. In this way, an integer number of chambers 1110 can be arranged in the circumferential and axial directions of the flow channel cavity 111, facilitating the arrangement of more chambers 1110, making the arrangement of the chambers 1110 more compact, and improving the space utilization rate of the flow channel cavity 111.
[0045] The size and number of the chambers 1110 can be designed according to the hydraulic diameter required by the system. For example, Figure 2 and Figure 3 As shown, the opening of the chamber 1110 can be set as a rectangle. The cross-section of the chamber 1110 can be set as a trapezoid, and the opening of the chamber 1110 gradually decreases along the radial direction of the flow channel main body 110. The circumferential corners of the chamber 1110 can be set as arcs to reduce the flow resistance of the fluid.
[0046] Furthermore, in some embodiments, as Figure 1 shown, the flow channel main body 110 is circumferentially divided into multiple zones with equal lengths, and the length of each zone is equal to the minimum length. The flow channel main body 110 is axially divided into multiple layers with equal heights, and the height of each layer is equal to the minimum height. The multiple chambers 1110 include a first chamber 1111 and at least two second chambers 1112 located in different layers from the first chamber 1111. The first chamber 1111 is located in multiple consecutive zones, and the at least two second chambers 1112 are arranged circumferentially in the same zone as the first chamber 1111 in the flow channel cavity 111, and the sum of the lengths of the at least two second chambers 1112 is equal to the sum of the lengths of the multiple consecutive zones. The lengths of the at least two second chambers 1112 are the same or different; and / or, as Figure 4 shown, the multiple chambers 1110 include a third chamber 1113 and at least two fourth chambers 1114 located in different zones from the third chamber 1113. The third chamber 1113 is located in multiple consecutive layers, and the at least two fourth chambers 1114 are arranged axially in the same layer as the third chamber 1113 in the flow channel cavity 111, and the sum of the heights of the at least two fourth chambers 1114 is equal to the sum of the heights of the multiple consecutive layers. The lengths of the at least two fourth chambers 1114 are the same or different.
[0047] The first chamber 1111 and at least two second chambers 1112 are respectively arranged in different layers of the runner main body 110. The first chamber 1111 straddles multiple consecutive zones, and the at least two second chambers 1112 are also arranged in the multiple consecutive zones. When the number of the second chambers 1112 is two, the lengths of the two second chambers 1112 may be equal or unequal, and the sum of the lengths of the two second chambers 1112 is equal to the length of the first chamber 1111. When the number of the second chambers 1112 is three or more, the lengths of all the second chambers 1112 may be all equal, or the lengths of some of the second chambers 1112 are equal, or the lengths of all the second chambers 1112 are unequal, and the sum of the lengths of all the second chambers 1112 is equal to the length of the first chamber 1111. Similarly, a third chamber 1113 and at least two fourth chambers 1114 are respectively arranged in different zones of the runner main body 110. The third chamber 1113 straddles multiple consecutive layers, and the at least two fourth chambers 1114 are also arranged in the multiple consecutive layers. When the number of the fourth chambers 1114 is two, the lengths of the two fourth chambers 1114 may be equal or unequal, and the sum of the lengths of the two fourth chambers 1114 is equal to the length of the third chamber 1113. When the number of the fourth chambers 1114 is three or more, the lengths of all the fourth chambers 1114 may be all equal, or the lengths of some of the fourth chambers 1114 are equal, or the lengths of all the fourth chambers 1114 are unequal, and the sum of the lengths of all the fourth chambers 1114 is equal to the length of the third chamber 1113. In this way, the chambers are continuously arranged and closely arranged in multiple consecutive zones and / or multiple consecutive layers, with high space utilization rate. Furthermore, arranging multiple chambers 1110 in the entire runner main body 110 according to this rule can fully utilize the space of the runner cavity 111 and greatly improve the space utilization rate.
[0048] Specifically, in Figure 5In the illustrated embodiment, the first partition 1121 and the second partition 1122 divide the flow channel cavity 111 into 16 chambers. The circumferential length of the flow channel main body 110 is 9 times the minimum length, and the axial height is 3 times the minimum height. The flow channel main body 110 is circumferentially divided into 9 zones with equal lengths and axially divided into 3 layers with equal heights. Chamber 1110a is provided in zones L1, L2, L3 and layer H1. Chamber 1110b is provided in zone L1 and layers H2, H3. Chamber 1110c is provided in zones L2, L3 and layer H2. Chamber 1110d is provided in zones L2, L3 and layer H3. Chamber 1110e is provided in zone L4 and layers H1, H2. Chamber 1110f is provided in zone L5 and layers H1, H2. Chamber 1110g is provided in zones L4, L5 and layer H3. Chamber 1110h is provided in zone L6 and layer H1. Chamber 1110i is provided in zone L7 and layer H1. Chamber 1110j is provided in zones L6, L7 and layer H2. Chamber 1110k is provided in zone L6 and layer H3. Chamber 1110l is provided in zone L7 and layer H3. Chamber 1110m is provided in zone L8 and layers H1, H2. Chamber 1110n is provided in zone L9 and layers H1, H2. Chamber 1110o is provided in zone L8 and layer H3. Chamber 1110p is provided in zone L9 and layer H3. Dividing 16 chambers 1110 on the relatively small flow channel cavity 111 results in a compact layout and very high space utilization rate.
[0049] The present disclosure also provides a multi-way valve 10, including the above multi-way valve spool 100, a multi-way valve body, and a seal. The multi-way valve spool 100 is rotatably disposed in the multi-way valve body, and the seal is disposed between the multi-way valve spool 100 and the multi-way valve body. By rotating the multi-way valve spool 100 in the multi-way valve body, various working mode switches of the multi-way valve 10 are realized. The seal is used for assembling and sealing between the multi-way valve spool 100 and the multi-way valve body to prevent fluid leakage between the multi-way valve spool 100 and the multi-way valve body when the multi-way valve 10 is working, and to ensure the sealing performance of the overall structure of the multi-way valve 10. Applying the above multi-way valve spool 100 with very high space utilization rate in the multi-way valve 10 enables the multi-way valve 10 to achieve more types of working mode switches and has high economic benefits.
[0050] The multi-way valve spool 100 and the multi-way valve body can be manufactured by injection molding, can also be made by metal casting, or can be a combination of part metal and part plastic. The seal can be an elastomer made of rubber material.
[0051] Further, in some embodiments, referring to Figure 2 and Figure 3As shown, a convex rib 1123 is provided on the side of the partition 112, and the convex rib 1123 protrudes from the surface of the partition 112. When the convex rib 1123 abuts against the seal, the contact area is reduced compared to the direct abutment between the partition 112 and the seal, thereby reducing the friction resistance between the multi-way valve core 100 and the seal, making it easier for the multi-way valve core 100 to rotate in the multi-way valve body. In addition, multiple convex ribs 1123 surround the corresponding chambers 1110, and the abutment and extrusion fit between the seal and the convex rib 1123 can ensure the independence of the multiple chambers 1110.
[0052] There is a step difference between the rib 1123 and the multi-way valve body, which is convenient for reducing the contact area when the multi-way valve core 100 rotates in the multi-way valve body, thereby reducing the friction resistance.
[0053] In some embodiments, the multi-way valve body is provided with a plurality of flow openings matching the chamber 1110, and at least two flow openings are connected through one chamber 1110 to form a fluid channel. The multi-way valve core 100 has a plurality of working modes. When the multi-way valve core 100 is in different working modes, at least some of the flow openings are connected through the chambers 1110 at different positions of the flow channel body 110 to form different fluid channels. Through the combination and transformation between different flow openings and different chambers 1110, the connection between different flow openings is realized, thereby forming different fluid channels, so as to realize the switching of the multi-way valve core 100 between different working modes. In this way, one multi-way valve core 100 can replace multiple valve cores, realize the integration of functions, and reduce the number of valves required to be used.
[0054] For example, the multiple flow channel openings include a first flow channel opening, a second flow channel opening, and a third flow channel opening. In one operating mode, the first flow channel opening and the second flow channel opening are connected through the first chamber 1111. In another operating mode, the first flow channel opening and the third flow channel opening are connected through the second chamber 1112.
[0055] In different working modes, the combinations of connected flow channel openings may be partially the same or completely different.
[0056] In some embodiments, the multi-way valve core 100 is provided with a limit portion 130, which is provided at one end of the flow channel main body 110, and the multi-way valve body is provided with a clamping portion matching the limit portion, and the multi-way valve limits the rotation angle of the multi-way valve core 100 through the cooperation between the limit portion 130 and the clamping portion. The multi-way valve core 100 can be positioned at the initial position and the final position in the multi-way valve body through the collision between the limit portion 130 and the clamping portion, so as to control the rotation angle of the multi-way valve core 100 in the multi-way valve body, and then switch the working mode of the multi-way valve core 100.
[0057] In some embodiments, the rotation angle of the multi-way valve spool is from 0° to 280°. More than 100 working modes of the multi-way valve spool can be realized.
[0058] A spline 121 can be provided on the drive shaft 120. The multi-way valve further includes a motor. The motor drives the transmission mechanism to rotate. The spline 121 is connected to the transmission mechanism, thereby driving the multi-way valve spool 100 to rotate within the multi-way valve body, changing the connection combination between the flow ports and the chambers 1110, so as to realize the switching of the fluid channels.
[0059] In Figures 5 to 10 the illustrated embodiment, the multi-way valve 10 is a six-way valve. There are 6 flow ports provided on the multi-way valve body for matching 16 chambers 1110. The multi-way valve spool 100 has five working modes. As Figure 6 shown, in the first working mode, the rotation angle of the multi-way valve spool 100 within the multi-way valve body is 0°. The flow port A and the flow port B are conducted through the chamber 1110a. The flow port E and the flow port F are conducted through the chamber 1110c. The flow port C and the flow port D are conducted through the chamber 1110d. As Figure 7 shown, in the second working mode, the rotation angle of the multi-way valve spool 100 within the multi-way valve body is 80°. The flow port B and the flow port E are conducted through the chamber 1110e. The flow port A and the flow port F are conducted through the chamber 1110f. The flow port C and the flow port D are conducted through the chamber 1110g. As Figure 8 shown, in the third working mode, the rotation angle of the multi-way valve spool 100 within the multi-way valve body is 160°. The flow port A and the flow port D are conducted through the chamber 1110f. The flow port E and the flow port F are conducted through the chamber 1110j. As Figure 9 shown, in the fourth working mode, the rotation angle of the multi-way valve spool 100 within the multi-way valve body is 200°. The flow port A and the flow port F are conducted through the chamber 1110m. The flow port D and the flow port E are conducted through the chamber 1110j. As Figure 10 shown, in the fifth working mode, the rotation angle of the multi-way valve spool 100 within the multi-way valve body is 280°. The flow port A and the flow port D are conducted through the chamber 1110m. The flow port B and the flow port E are conducted through the chamber 1110n. The flow port C and the flow port F are conducted through the chamber 1110b.
[0060] Referring to Figure 11As shown, the present disclosure also provides a thermal management system 20, including the above-mentioned multi-way valve 10 and a plurality of external pipelines 30. A plurality of flow ports of the multi-way valve 10 are communicated with the plurality of external pipelines 30. Thus, when the multi-way valve spool 100 switches the working mode, the combination of the communicated flow ports changes, so that different combinations of external pipelines are communicated to meet the connection requirements between different external pipelines 30 under different working conditions of the thermal management system 20. By arranging the multi-way valve 10 in the thermal management system, the on-off of different pipelines can be realized, simplifying the vehicle-mounted system and reducing the number of control actuators. The weight, volume and cost of the thermal management system 20 are reduced.
[0061] The present disclosure also provides a new energy vehicle, including a motor, a battery and the above-mentioned thermal management system 20. The motor and the battery are connected to the thermal management system 20. The new energy vehicle realizes the refrigeration and heating of the battery and the motor through the thermal management system 20, so that the temperatures of the battery and the motor are within a suitable working range under various working conditions. By applying the thermal management system 20 with a small volume and light weight in the new energy vehicle, the manufacturing cost of the new energy vehicle is greatly reduced.
