[0036] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in combination with the specific implementation methods of this application and the corresponding drawings. Obviously, the described implementation methods are only part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] The utility model provides a sealing component of a multi-way valve, the sealing component comprising:

[0039] An outer ring portion, the outer ring portion having an outer side surface and an inner side surface opposite to each other;

[0040] An inner ring portion, the inner ring portion is arranged at a distance from the outer ring portion;

[0041] At least one connecting portion, the at least one connecting portion connecting the outer ring portion and the inner ring portion, and separating the area between the outer ring portion and the inner ring portion to form a plurality of fluid channels independent of each other, at least one of the plurality of fluid channels matches a flow channel port of the multi-way valve to allow fluid to pass through;

[0042] The inner side surface of the outer ring portion is closer to the fluid channel than the outer side surface of the outer ring portion;

[0043] The outer ring portion also has a top side surface and a bottom side surface opposite to each other, wherein the top side surface and the bottom side surface are both located between the outer side surface and the inner side surface, and the top side surface and the bottom side surface are both concave surfaces;

[0044] The outer side surface is a plane, and the inner side surface is a concave surface; or, both the outer side surface and the inner side surface are concave surfaces, and the inner side surface is more concave than the outer side surface.

[0045] like Figure 1-Figure 3This embodiment provides a sealing member 100 , which includes an outer ring portion 110 , an inner ring portion 120 and a plurality of connecting portions 130 .

[0046] The outer ring portion 110 has an outer side surface 111 and an inner side surface 112 relative to each other. The inner ring portion 120 is arranged at a distance from the outer ring portion 110. A plurality of connecting portions 130 connect the outer ring portion 110 and the inner ring portion 120, and separate the area between the outer ring portion 110 and the inner ring portion 120 to form a plurality of independent fluid channels 140. At least one of the plurality of fluid channels 140 matches a flow channel port of a multi-way valve to allow fluid to pass through.

[0047] Specifically, the inner side surface 112 of the outer ring portion 110 is closer to the fluid channel 140 than the outer side surface 111 of the outer ring portion 110 .

[0048] The outer ring portion 110 further has a top side surface 113 and a bottom side surface 114 opposite to each other. The top side surface 113 and the bottom side surface 114 are both located between the outer side surface 111 and the inner side surface 112 and respectively connect the outer side surface 111 and the inner side surface 112 .

[0049] The top side surface 113 and the bottom side surface 114 of the outer ring portion 110 are both concave surfaces. When the coolant flowing through the flow channel breaks through the inner side surface 112 of the outer ring portion 110 and flows from the upper and lower ends of the inner side surface 112 of the outer ring portion 110 to the top side surface 113 and the bottom side surface 114, since the top side surface 113 and the bottom side surface 114 are both concave surfaces, the top side surface 113 and the bottom side surface 114 can accommodate a small amount of coolant.

[0050] In one embodiment, the outer side surface 111 of the outer ring portion 110 is a plane, and the inner side surface 112 of the outer ring portion 110 is a concave surface. When the multi-way valve and the flow channel plate are assembled and connected, the outer side surface 111 of the outer ring portion 110 of the seal can provide a greater support force toward the multi-way valve and the end surface of the flow channel plate relative to the inner side surface 112, and the sealing performance is better. Even if the coolant breaks through the inner side surface 112, the outer side surface 111 can effectively prevent the coolant from leaking outward.

[0051] In another embodiment, the outer side surface 111 of the outer ring portion 110 and the inner side surface 112 of the outer ring portion 110 are both concave surfaces, and the inner side surface 112 is more concave than the outer side surface 111. Similarly, when the multi-way valve and the flow channel plate are assembled and connected, the outer side surface 111 of the outer ring portion 110 of the seal can provide a greater supporting force toward the end surface of the multi-way valve and the flow channel plate than the inner side surface 112, and the sealing performance is better.

[0052] Of course, the concave surfaces referred to here are all arc-shaped concave surfaces. The degree of concavity of the inner side surface 112, the top side surface 113, and the bottom side surface 114 of the outer ring portion 110 can be set to be different. The utility model does not limit this and can be specifically adjusted according to actual product requirements and actual applications.

[0053] Specifically, the top side surface 113 and the bottom side surface 114 of the outer ring portion 110 intersect with the outer side surface 111 thereof, respectively, to form two first sealing portions 115. The top side surface 113 and the bottom side surface 114 of the outer ring portion 110 intersect with the inner side surface 112, respectively, to form two second sealing portions 116. In this embodiment, the sealing member 100 is disposed between the multi-way valve and the flow channel plate, and the multi-way valve and / or the flow channel plate are provided with a mounting groove for mounting the sealing member 100. When the sealing member 100 is assembled with the multi-way valve and / or the flow channel plate, the first sealing portion 115 and the second sealing portion 116 of the sealing member 100 are simultaneously clamped in the mounting groove.

[0054] In one embodiment, when the sealing member 100 is assembled with the multi-way valve and / or the flow channel plate, the first sealing portion 115 is in surface contact with the mounting groove, and the second sealing portion 116 is in line contact with the mounting groove. That is, the first sealing portion 115 has a larger contact area with the mounting groove than the second sealing portion 116, and has better sealing performance, that is, the first sealing portion 115 is more capable of preventing the coolant from leaking out than the second sealing portion 116.

[0055] In another embodiment, when the seal 100 is assembled with the multi-way valve and / or the flow channel plate, the first sealing portion 115 and the mounting groove and the second sealing portion 116 and the mounting groove are in surface contact, and the contact area between the first sealing portion 115 and the mounting groove is greater than the contact area between the second sealing portion 116 and the mounting groove. Similarly, the first sealing portion 115 has a larger contact area with the mounting groove than the second sealing portion 116, and has better sealing performance, that is, the first sealing portion 115 is more capable of preventing the coolant from leaking out than the second sealing portion 116.

[0056] Specific combination Figure 2 and Figure 3 , Figure 2 It is a cross-sectional view of the seal 100 along its installation direction AA' (the installation direction of the seal 100 can be understood as the flow direction of the coolant in the multi-way valve and the flow channel plate), and the plane perpendicular to the installation direction of the seal 100 is defined as the first plane. BB' in the figure is the radial direction of the seal 100 on the same first plane. Figure 3 for Figure 2 Schematic diagram of the enlarged structure of the middle area S.

[0057] The same first plane intersects with the first sealing portion 115 and the second sealing portion 116 to form a first cross section 1151 and a second cross section 1161, and a radial width w1 of the first cross section 1151 is greater than a radial width w2 of the second cross section 1161. Figure 5The cross-sectional view of the outer ring portion 110 when the same first plane intersects with the outer ring portion 110, i.e., the cross-sectional view of the outer ring portion 110 along the BB' direction, the first cross-sectional view 1151 and the second cross-sectional view 1161 are both annular planes, and the radial width w1 of the first cross-sectional view 1151 is greater than the radial width w2 of the second cross-sectional view 1161. That is, when the multi-way valve and the flow channel plate are assembled and connected, the first sealing portion 115 can provide a greater supporting force toward the end surface of the multi-way valve and the flow channel plate than the second sealing portion 116, and in the process of the multi-way valve and the flow channel plate being assembled and connected to squeeze the seal 100, the first sealing portion 115 has a smaller deformation than the second sealing portion 116, so the first sealing portion 115 has better sealing performance than the second sealing portion 116, and can more effectively prevent the coolant from leaking outward.

[0058] At the same time, a plane perpendicular to the first plane and perpendicular to the tangent direction of the outer side surface 111 of the outer ring portion 110 is defined as a second plane, and a cross section formed by the intersection of the second plane and the outer ring portion 110 is a first cross section. Figure 2-Figure 4 The cross section of the outer ring portion 110 is shown.

[0059] like Figure 4 As shown, when the first plane is tangent to the first sealing portion 115, the first cross section 1151 is a plane; when the first plane is tangent to the second sealing portion 116, the second cross section 1161 is a line. Figure 6 In the top view of the outer ring portion shown, when the first plane is tangent to the first sealing portion 115, the first section 1151 is a circular plane (the shaded part in the figure); when the first plane is tangent to the second sealing portion 116, the second section 1161 is a circular line. Correspondingly, when the first plane is tangent to the first sealing portion 115, the first section 1151 is a straight line on the first section; when the first plane is tangent to the second sealing portion 116, the second section 1161 is a point along the first section. When the multi-way valve and the flow channel plate are assembled and connected, and the outer ring portion 110 is clamped on the end surface of the multi-way valve and the flow channel plate, the first sealing portion 115 has a larger contact area with the multi-way valve and the end surface of the flow channel plate than the second sealing portion 116, and has better sealing performance and can better prevent the leakage of coolant.

[0060] Specifically, when the outer side surface 111 of the outer ring portion 110 is a plane and the inner side surface 112 of the outer ring portion 110 is a concave surface, the first cross section is “K”-shaped.

[0061] More specifically, the outer side surface 111 and the inner side surface 112 of the outer ring portion 110 are smoothly connected to the top side surface 113 and the bottom side surface 114 thereof.

[0062] Similarly, the inner ring 120 has an outer side 121 and an inner side 122 opposite to each other, and the outer side 121 of the inner ring 120 is closer to the outer ring 110 than the inner side 122 of the inner ring 120. The inner ring 120 is used to prevent the coolant flowing through the flow channel from leaking into the multi-way valve.

[0063] The outer side surface 121 and the inner side surface 122 of the inner ring portion 120 are both concave surfaces, and the outer side surface 121 and the inner side surface 122 of the inner ring portion 120 have the same concave degree.

[0064] Similarly, the inner ring portion 120 also has a top side surface 123 and a bottom side surface 124 connecting the outer side surface 121 and the inner side surface 122 thereof, and the top side surface 123 and the bottom side surface 124 of the inner ring portion 120 are both concave surfaces, and the concavity of the two is the same. In addition, the outer side surface 121 and the inner side surface 122 of the inner ring portion 120 are connected to the top side surface 123 and the bottom side surface 124 thereof at the connection points with each other in a smooth transition.

[0065] A plane perpendicular to the first plane and perpendicular to the tangential direction of the outer side surface 121 of the inner ring portion 120 is defined as a third plane, and a cross section formed by the intersection of the third plane and the inner ring portion 120 is defined as a second cross section. Figure 2 The cross section shown in the middle inner ring portion 120. That is, the second cross section is in an "X" shape.

[0066] Refer again Figure 1 The connection part 130 extends radially along the seal 100, and the four surfaces of the connection part 130 are all concave surfaces, and the concave degrees of the two opposite concave surfaces are the same, and the connection between the two adjacent surfaces is smoothly transitioned. The connection part 130 is used to prevent the coolant between the adjacent flow channel openings from leaking each other.

[0067] A plane perpendicular to the first plane and the extending direction of the connecting portion 130 is defined as a fourth plane, and a cross section formed by the intersection of the fourth plane and the connecting portion 130 is a third cross section, which is a cross section of the connecting portion 130 along the CC' direction in the figure.

[0068] Likewise, the third cross section is in an "X" shape.

[0069] Furthermore, the seal 100 further includes a plurality of protrusions 150, which are disposed on the wall of the fluid channel 140. When the multi-way valve, the flow channel plate and the seal are assembled, the protrusions 150 can facilitate the seal 100 to be clamped in the sealing grooves of the multi-way valve and the flow channel plate.

[0070] This embodiment also provides a thermal management system, such as Figure 6As shown, the thermal management system includes a multi-way valve 200, a flow channel plate 300 and a seal 100 of the multi-way valve as described above, the multi-way valve 200 is provided with a plurality of flow channel openings, the flow channel plate 300 is provided with a plurality of channels corresponding to the number of the flow channel openings, and the seal 100 is provided between the multi-way valve 200 and the flow channel plate 300 for sealing the joint position of the multi-way valve 200 and the flow channel plate 300.

[0071] Specifically, mounting grooves are provided at corresponding positions on the end faces of the multi-way valve 200 and the flow channel plate 300. The mounting grooves on the end faces of the multi-way valve 200 are provided around the flow channel openings, and the mounting grooves on the end faces of the flow channel plate 300 are provided around the channels. Figure 7 It is shown in the figure that when the multi-way valve 200, the flow channel plate 300 and the seal 100 are assembled, the first sealing portion 115 and the second sealing portion 116 on the outer ring portion of the seal 100 are completely stuck in the installation groove. When the multi-way valve 200 and the flow channel plate 300 are pressed together and the two end surfaces are in contact, the first sealing portion 115 and the second sealing portion 116 are squeezed and deformed in the installation groove. Since the first sealing portion 115 can provide a greater supporting force toward the end surface of the multi-way valve 200 and the flow channel plate 300 than the second sealing portion 116 and has a larger contact area with the installation groove, that is, in the process of the multi-way valve 200 and the flow channel plate 300 being engaged and squeezing the seal 100, the first sealing portion 115 has a smaller deformation than the second sealing portion 116, so the first sealing portion 115 has better sealing performance than the second sealing portion 116 and can more effectively prevent the coolant from leaking to the outside.

[0072] When the multi-way valve 200, the flow channel plate 300 and the seal 100 are assembled, the extension surface of the joint end surface of the multi-way valve 200 and the flow channel plate 300 passes through the seal 100. Specifically, the extension surface of the joint end surface of the multi-way valve 200 and the flow channel plate 300 passes through the middle plane of the seal 100 along the thickness direction thereof, so as to ensure that the installation groove of the multi-way valve 200 and the installation groove of the flow channel plate 300 have the same degree of extrusion on the seal 100, that is, the sealing properties of the seal 100 on the end surface of the multi-way valve 200 and the end surface of the flow channel plate 300 are the same, so as to prevent the cooling liquid from overflowing from the end surface side of the multi-way valve 200 or from the end surface of the flow channel plate 300 due to the different sealing properties of the seal 100 on the end surface of the multi-way valve 200 and the end surface of the flow channel plate 300.

[0073] To summarize, the utility model sets the outer side surface of the outer ring portion of the seal as a plane, and the inner side surface as a concave surface, or both are set as concave surfaces, and the inner side surface is more concave than the outer side surface, that is, when the multi-way valve and the flow channel plate are assembled and connected, the seal is located between the two to seal the flow channel opening, then the outer side surface of the outer ring portion of the seal can provide a greater supporting force toward the multi-way valve and the end face of the flow channel plate relative to the inner side surface, and the first sealing portion of the outer ring portion has a larger contact area with the end face of the multi-way valve / flow channel plate than the second sealing portion, then the seal of the multi-way valve provided by the utility model has better sealing performance than the "X"-shaped sealing ring in the prior art, and can effectively prevent the coolant from leaking outward even under high temperature and high pressure conditions.

[0074] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0075] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
