Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a valve, a thermal management system and a vehicle. Background Art

[0002] Automotive thermal management systems are becoming increasingly sophisticated, and their piping is becoming increasingly complex. To achieve precise control, switching between pipelines is often accomplished using a combination of three-way valves, four-way valves, and / or other water valves. Traditional valves used in automotive thermal management systems or other fluid flow paths often have relatively simple structures, with the flow channels typically directing fluid inflow and outflow through a single end face of the valve body. This limits the number of pipelines that can be integrated outside the valve, restricting the spatial integration of the valve and its associated piping. Utility Model Content

[0071] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0072] Referring Figures 1 to 8 As shown, according to the first aspect of the present application, a valve 100 is provided. The valve 100 can be used, for example, in a pipeline for refrigerant, coolant, etc. to flow in a thermal management system on a vehicle, as a spare part for controlling the flow direction of refrigerant and coolant in the pipeline. Of course, the valve 100 can also be used in other types of pipelines, which will not be elaborated here.

[0073] The valve 100 provided by the present application includes: a valve core 110 and a valve body 120.

[0074] Among them, the valve body 120 is formed with a valve cavity 121 and a plurality of valve ports. The plurality of valve ports communicate with the valve cavity 121 and are used to connect external pipelines. The valve core 110 is accommodated in the valve cavity 121. The valve body 120 and the valve core 110 form a rotational connection about the rotation axis L1.

[0075] The valve core 110 is formed with a first fluid passage 111. The first fluid passage 111 is used to communicate two valve ports, and the first fluid passage 111 is also used for fluid media to pass through. The fluid media can be, for example, hydraulic oil, cooling water, refrigerant, compressed gas, etc. The first fluid passage 111 extends from a first position of the valve core 110 to a second position; the first position and the second position are in different positions both axially and circumferentially of the valve core 110. Thus, during the flow of the fluid media between the first position and the second position in the first fluid passage 111, the fluid media can flow from a certain position relative to the valve body to another position that is different from this position both circumferentially and axially along the valve core 110.

[0076] With the above solution, when the fluid media flows in the first fluid passage 111, it can flow between the first position and the second position, and further change the position where the fluid media enters the first fluid passage 111 and the position where the fluid media flows out of the first fluid passage 111 both axially and circumferentially along the valve core 110. That is, the fluid can flow to more positions around the valve body 120, rather than being limited to a certain end face. This makes the spatial area available for connecting pipelines on the surface of the valve 100 more, that is, more pipelines can be arranged on the valve body 120 in space, thereby improving the spatial integration degree of the valve 100 and the pipelines cooperating with it.

[0077] In some embodiments, on the path extending from the first position to the second position, the extending direction of the first fluid passage 111 is inclined with respect to the rotation axis L1.

[0078] It can be understood that when the fluid medium enters the interior of the valve body 120 and flows in the first fluid passage 111, the tangential direction of the fluid medium flow is consistent with the extending direction of the first fluid passage 111, that is, the direction of the fluid medium flow is consistent with the extending direction of the first fluid passage 111, so as to guide the flow of the fluid medium by using the first fluid passage 111.

[0079] The tangential direction of the fluid medium flow mentioned in the present application refers to the direction when the fluid medium flows in the flow passage formed by enclosing the wall surface of the first fluid passage 111 formed by the valve core 110 and the wall surface of the valve body 120 forming the valve cavity 121. By defining that the extending direction of the first fluid passage 111 is inclined to the rotation axis L1, in some cases, for example, when the fluid medium flows along a direction parallel to or inclined to the straight line where the rotation axis L1 is located, the tangential direction of the fluid medium flow is fixed, that is, the included angle formed by the tangential direction of the fluid medium flowing in the first fluid passage 111 and the rotation axis L1 is a fixed value, and this value is not a right angle, that is, the first fluid passage 111 does not extend along the radial direction of the valve core 110. This setting reduces the obstructive effect of the wall surface of the first fluid passage 111 formed by the valve core 110 on the flow of the fluid medium when the fluid medium flows in the first fluid passage 111, that is, it is beneficial to reduce the flow resistance encountered when the fluid medium flows.

[0080] In some embodiments, on the path extending from the first position to the second position, the included angle formed by the extending direction of the first fluid passage 111 and the rotation axis L1 changes continuously. When the fluid medium moves along a non-linear flow trajectory, the present application limits that in some time periods, the included angle formed by the extending direction of the first fluid passage 111 and the rotation axis L1 changes continuously. Referring to the previous description, at this time, the included angle formed by the tangential direction of the fluid medium flow and the rotation axis L1 also changes continuously, that is, the fluid medium flows in a straight line or a curved line in the first fluid passage 111, and there is no corner or sudden change in the rotation direction during the flow process. Therefore, the fluid medium flows smoothly in the first flow passage with small kinetic energy loss, thereby reducing the flow resistance when the fluid medium flows in the valve 100.

[0081] In some embodiments, referring to Figures 3 to 6 As shown, the first fluid passage 111 is configured to be a slot spirally extending on the surface of the valve core 110. In a specific solution, the slot extending spirally can guide the fluid medium to change the flow direction therein, and the kinetic energy loss of the fluid medium is relatively small.

[0082] In some embodiments, referring to Figure 3As shown, the valve core 110 is configured to have a cylindrical surface formed by rotating around the rotation axis L1. The slot is recessed in the cylindrical surface. Compared with the valve core 110 having a polyhedron or other shape, this configuration is beneficial to maintaining the consistency of the depth of each part of the slot, so that the fluid medium can stably pass through the first fluid passage 111. The cylindrical surface fits with the surface of the valve body 120 that forms the valve cavity 121 to form a contact seal between the valve body 120 and the valve core 110, that is, referring to Figure 3 As shown, the inner wall of the valve cavity 121 formed by the valve body 120 can also be configured as a cylindrical curved surface, which cooperates with the surface of the valve core 110 to limit the rotation of the valve core 110 in the valve cavity 121 and prevent the fluid medium from leaking out of the first fluid passage 111 through the gap between the inner wall of the valve cavity 121 and the surface of the valve core 110.

[0083] In some embodiments, the valve 100 further includes: a seal 130. Wherein, the seal 130 is disposed between the inner wall of the valve cavity 121 formed by the valve body 120 and the valve core 110 to seal the valve cavity 121. In a specific solution, referring to Figure 2 and Figure 7 As shown, one end of the valve cavity 121 is open for the valve core 110 to be inserted. The seal 130 is, for example, an O-ring sleeved on the cylindrical surface of the valve core 110, and is disposed near the open end of the valve cavity 121 to close the open end of the valve cavity 121 and prevent the wall fluid medium from leaking out of the valve cavity 121. More specifically, a seal groove 117 is provided at the end of the valve core 110 near the open end of the valve cavity 121, and the seal 130 is embedded in the seal groove 117 to realize the positioning and installation of the seal 130.

[0084] In some embodiments, referring to Figure 1 and Figure 2 As shown, the valve 100 further includes: a driver 140. Wherein, the driver 140 is used to drive the valve core 110 to rotate relative to the valve body 120. It can be understood that by driving the valve core 110 to rotate through the driver 140, the valve core 110 can be rotated to a first relative position to connect the first valve port 122 and the second valve port 123, or rotated to another position to disconnect the first valve port 122 and the second valve port 123.

[0085] In a specific solution, the driver 140 drives the valve core 110 to rotate in an electric control manner. For example, referring to Figure 1 and Figure 2 As shown, the driver 140 is configured as a motor fixedly disposed on the valve body 120. The motor is fixed at the open end of the valve cavity 121 and can limit the axial movement of the valve core 110. Correspondingly, a connection part 112 corresponding to the connection with the motor can be provided on the valve core 110. In the appendix Figure 2In the disclosed solution, the connecting portion 112 is, for example, a protrusion formed at the end of the valve core 110, which is connected to the output shaft of the motor by mutual interlocking, pin fixing, etc., so that when the motor is working, it drives the valve core 110 to rotate a corresponding angle to achieve a relative position change of the valve core 110 relative to the valve body 120.

[0086] In some embodiments, the valve port includes a first valve port 122 and a second valve port 123. The valve core 110 is rotatably connected to the valve body 120 about a rotation axis L1, such that the valve core 110 has at least a first relative position relative to the valve body 120. When the valve core 110 is in the first relative position, the first valve port 122 communicates with the first fluid channel 111 in the first position, and the second valve port 123 communicates with the first fluid channel 111 in the second position. In other words, the first valve port 122 and the second valve port 123 communicate through the first fluid channel 111, allowing fluid medium to flow between the first valve port 122 and the second valve port 123 through the first fluid channel 111.

[0087] It is understood that because the first and second positions of the first fluid channel 111 are arranged at different locations in the axial and circumferential directions of the valve core 110, the first valve port 122 and the second valve port 123 are located at different positions along the direction of the rotation axis L1 of the valve body 120. In other words, the projection positions of the first valve port 122 and the second valve port 123 on the plane with the rotation axis L1 as the normal are arranged at different positions. This solution results in different flow directions of the fluid medium when entering and exiting the first fluid channel 111.

[0088] For specific plans, refer to Figure 1 and Figure 2 As shown, the exterior of the valve body 120 can be configured into a polyhedron shape, such as a rectangular parallelepiped as shown in the accompanying drawings, wherein the first valve port 122 and the second valve port 123 are respectively configured on two different end faces of the rectangular parallelepiped, so that the fluid medium is guided by the first flow channel and changes the flow direction when flowing between the first valve port 122 and the second valve port 123. Correspondingly, when the overall volume of the valve 100 is limited, this method can configure more interfaces on the periphery of the valve body 120 to introduce or discharge the fluid medium.

[0089] The fluid medium in the first flow channel flows at least in the direction of the rotation axis L1. In other words, the first valve port 122 and the second valve port 123 are arranged at different positions of the valve body 120 along the direction of the rotation axis L1, so as to facilitate the configuration of a corresponding flow channel for the fluid medium to flow in the space occupied by the entity of the valve core 110.

[0090] Based on the rotation of the valve core 110 relative to the valve body 120, the valve core 110 can be configured with more channels for the flow of the fluid medium, and the valve body 120 can be configured with more openings for introducing or withdrawing the fluid medium, thereby enabling the valve 100 to control the flow of the fluid medium between different external pipelines. The following examples illustrate some specific solutions for configuring different channels on the valve 100 to connect different external pipelines.

[0091] In some embodiments, the valve port further includes a third valve port 124 . Correspondingly, the valve core 110 further includes a second fluid channel 113 .

[0092] The third valve port 124 is connected to the valve cavity 121, and the third valve port 124 and the first valve port 122 are located at the same end of the valve body 120 along the rotation axis L1. The second fluid channel 113 is connected to the first fluid channel 111. When the valve core 110 is in the first relative position, the third valve port 124 is connected to the first valve port 122 via the second fluid channel 113. In other words, by configuring the second fluid channel 113, the valve core 110 can connect the first valve port 122, the second valve port 123, and the third valve port 124 when in the first relative position, allowing the fluid medium to flow between multiple external pipelines.

[0093] In some embodiments, reference Figure 1 and Figure 4 As shown, the valve port further includes a fourth valve port 125 . Correspondingly, the valve core 110 is further provided with a third fluid channel 114 .

[0094] Among them, the fourth valve port 125 is connected to the valve cavity 121, and the fourth valve port 125 and the second valve port 123 are arranged at one end of the valve body 120 away from the first valve port 122 along the direction of the rotation axis L1. The third fluid channel 114 is connected to the first fluid channel 111, and is respectively arranged at two opposite ends of the first fluid channel 111 with the second fluid channel 113. The valve core 110 has a second relative position relative to the valve body 120. When the valve core 110 is in the first relative position, the fourth valve port 125 is disconnected from the third fluid channel 114. When the valve core 110 is in the second relative position, the second valve port 123 is connected to the fourth valve port 125 through the third fluid channel 114, and the third valve port 124 is connected to the fourth valve port 125 through the first fluid channel 111.

[0095] With this solution, when the valve core 110 moves between the first relative position and the second relative position, the relative on-off relationship between the first valve port 122, the second valve port 123, the third valve port 124 and the fourth valve port 125 changes to change the flow direction of the fluid medium to adapt to different usage requirements.

[0096] More interfaces connected to external pipelines can be further configured on the valve body 120, or the communication relationship between different external pipelines connected through the valve 100 can be adjusted by configuring the spool 110 to have more relative positions relative to the valve body 120, so as to more flexibly change the flow direction of the fluid medium and make the valve 100 suitable for integrally connecting more complex pipeline designs.

[0097] In some embodiments, the valve ports further include: a fifth valve port 126 and a sixth valve port 127.

[0098] Among them, the fifth valve port 126 communicates with the valve cavity 121, and the third valve port 124 and the fifth valve port 126 are arranged at the same end of the valve body 120 along the rotation axis L1 direction. The sixth valve port 127 communicates with the valve cavity 121, and the fourth valve port 125 and the sixth valve port 127 are arranged at the same end of the valve body 120 along the rotation axis L1 direction. Correspondingly, the spool 110 has a third relative position relative to the valve body 120. When the spool 110 is in the third relative position, the fifth valve port 126 and the sixth valve port 127 are connected through the second fluid passage 113 and the first fluid passage 111, and the sixth valve port 127 and the fourth valve port 125 are connected through the third fluid passage 114.

[0099] In a specific solution, the spool 110 has a fourth relative position relative to the valve body 120. When the spool 110 is in the fourth relative position, the sixth valve port 127 and the fifth valve port 126 are connected through the third fluid passage 114 and the first fluid passage 111. The first valve port 122 and the fifth valve port 126 are connected through the second fluid passage 113.

[0100] As an alternative solution, more channels for fluid medium flow can also be configured on the spool 110 to realize more choices of flow directions of the fluid medium between different external pipelines by using the valve 100.

[0101] Refer to Figure 4 and Figure 5 As shown, in some embodiments, the spool 110 is further provided with: a fourth fluid passage 115. Among them, the fourth fluid passage 115 is arranged at an interval from the first fluid passage 111. When the spool 110 is in the second relative position, the first valve port 122 and the fifth valve port 126 are connected through the fourth fluid passage 115.

[0102] In some embodiments, when the spool 110 is in the third relative position, the first valve port 122 and the third valve port 124 are connected through the fourth fluid passage 115.

[0103] In some embodiments, the valve core 110 is further provided with a fifth fluid passage 116. The fifth fluid passage 116 is arranged at an interval from the first fluid passage 111. When the valve core 110 is in the first relative position, the fourth valve port 125 and the sixth valve port 127 are communicated through the fifth fluid passage 116.

[0104] In some embodiments, when the valve core 110 is in the fourth relative position, the second valve port 123 and the fourth valve port 125 are communicated through the fifth fluid passage 116.

[0105] It can be understood that during the rotation of the valve core 110 relative to the valve body 120, while some valve ports on the valve body 120 are communicated through the corresponding flow channels on the valve core 110, some other valve ports are disconnected due to the change in the relative positions of the valve core 110 and the valve body 120, so as to realize changing the flow direction of the fluid medium in the external pipeline by using the valve 100. The following makes an exemplary description of the on-off relationship changes between some valve ports of the valve body 120 when the relative position of the valve core 110 of some specific valves 100 shown in the drawings changes relative to the valve body 120, so as to clearly elaborate the inventive concept of the present application.

[0106] Refer to Figure 2 As shown, for exemplary illustration, the valve body 120 is integrally configured to be in a cuboid shape, and the valve core 110 is integrally in a cylindrical shape with a connecting portion 112 provided at one end. A valve cavity 121 in a cylindrical shape for inserting the valve core 110 is provided in the valve body 120, and the valve core 110 is rotatably arranged on the valve body 120 along the rotation axis L1.
