[0001] The present invention relates to the field of thermal management technology, and particularly relates to a thermal management component. Background Art

[0002] In a vehicle thermal management system, different thermal management components are connected through interface parts, and a seal is arranged between the interface parts to ensure the normal flow of fluid in the thermal management component. When the position deviation between the interface parts is large, traditional radial seals and axial seals will not be able to meet the sealing requirements of the thermal management component, resulting in leakage of the thermal management component. Utility Model Content

[0003] The purpose of this application is to provide a thermal management component that can improve the sealing effectiveness of the thermal management component.

[0004] This application discloses a thermal management component, including a first interface part, a second interface part and a seal. The seal includes a main body part, a first sealing part and a second sealing part. The seal has a channel. The first sealing part and the second sealing part are arranged along the axial direction of the channel. The main body part extends along the axial direction of the channel to connect the first sealing part and the second sealing part. At least one of the first sealing part and the second sealing part is an integral structure with the main body part. The first sealing part circumferentially surrounds the channel, and the second sealing part circumferentially surrounds the channel. The first sealing part protrudes from the main body part towards the first interface part, and the second sealing part protrudes from the main body part towards the second interface part. The first sealing part abuts against the first interface part, and the second sealing part abuts against the second interface part.

[0005] According to the thermal management component provided by the technical solution of this application, the first sealing part and the second sealing part of the seal are arranged along the axial direction of the channel. The main body part extends along the axial direction of the channel to connect the first sealing part and the second sealing part. Both the first sealing part and the second sealing part circumferentially surround the channel. The first sealing part protrudes from the main body part towards the first interface part and abuts against it, and the second sealing part protrudes from the main body part towards the second interface part and abuts against it. When the position deviation between the first interface part and the second interface part is large, the seal provided by this technical solution has a certain extension in the axial direction of the channel, so that it can deflect relatively to adapt to the position deviation between the interface parts. After the seal deflects, the two sealing parts can still abut against the two interface parts relatively, ensuring the sealing effectiveness between the interface parts of the thermal management component. In addition, at least one of the first sealing part and the second sealing part in this technical solution is an integral structure with the main body part. Therefore, when the seal deflects, the leakage risk caused by the position offset between the sealing part and the main body part can be reduced. Description of the Drawings

Detailed implementation manners

[0019] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Reference Figure 1 And Figure 3, an embodiment of the present application provides a thermal management component, which is specifically designed for the sealed connection between two interface parts of the thermal management component to improve the sealing effectiveness at the connection of the two interface parts and inhibit the leakage of fluid in the thermal management component. The thermal management component includes a first interface part 11, a second interface part 21, and a seal 3. The seal 3 includes a main body part 33, a first seal part 31, and a second seal part 32. The seal 3 has a channel 30. The first seal part 31 and the second seal part 32 are arranged along the axial direction of the channel 30, that is, the first seal part 31 and the second seal part 32 are arranged along the axial direction of the channel 30. The main body part 33 extends along the axial direction of the channel 30 to connect the first seal part 31 and the second seal part 32. It is equivalent to that the first seal part 31 and the second seal part 32 are connected by the main body part 33 with a certain extension distance, but it is not limited to that the extension distance of the main body part 33 in the axial direction of the channel 30 is greater than the distance between the first seal part 31 and the second seal part 32. At least one of the first seal part 31 and the second seal part 32 is integrally structured with the main body part 33. For example, one of the seal parts is integrally structured with the main body part 33, and the other seal part is sleeved on the main body part 33 as a sealing ring, or sleeved on the interface part. The main body part 33 abuts against the outer ring of the sealing ring. The first seal part 31 circumferentially surrounds the channel 30, and the second seal part 32 circumferentially surrounds the channel 30. The first seal part 31 protrudes from the main body part 33 towards the first interface part 11, and the second seal part 32 protrudes from the main body part 33 towards the second interface part 21. In this embodiment, the first seal part 31 forms a closed-loop raised structure around the channel 30, and the second seal part 32 forms a closed-loop raised structure around the channel 30. The first seal part 31 abuts against the first interface part 11, and the second seal part 32 abuts against the second interface part 21. In this embodiment, the seal 3 has a certain extension in the axial direction of the channel 30, so that it can allow a certain deflection and can adapt to the position deviation between the first interface part 11 and the second interface part 21 by relative deflection. After the seal 3 deflects, the two seal parts can still have a certain abutment against the two interface parts. Compared with the traditional radial sealing and end face sealing methods, the setting of this seal 3 can adapt to a greater deviation between the two interface parts and ensure the sealing effectiveness between the interface parts of the thermal management component. In addition, in this technical solution, at least one of the first seal part 31 and the second seal part 32 is integrally structured with the main body part 33, preferably both seal parts are integrally structured with the main body part 33. Therefore, when the seal 3 deflects, there will be no insufficient compression amount or gap between the seal part and the main body part 33, which can reduce the leakage risk caused by the position offset between the seal part and the main body part.

[0021] Reference Figure 1 and Figure 2, in an embodiment of the present application, the first interface portion 11 has a first receiving cavity 110, the second interface portion 21 has a second receiving cavity 210, the first sealing portion 31 is located in the first receiving cavity 110, the second sealing portion 32 is located in the second receiving cavity 210, the first sealing portion 31 is circumferentially arranged along one port of the channel 30, the second sealing portion 32 is circumferentially arranged along the other port of the channel 30, the first sealing portion 31 protrudes from the outer peripheral wall of the main body portion 33 towards the first interface portion 11, the second sealing portion 32 protrudes from the outer peripheral wall of the main body portion 33 towards the second interface portion 21, the first sealing portion 31 abuts against the inner peripheral wall of the first interface portion 11, and the second sealing portion 32 abuts against the inner peripheral wall of the second interface portion 21. In some other embodiments, one of the first sealing portion 31 and the second sealing portion 32 abuts against the outer peripheral wall of one of the interface portions. Refer to Figure 2 , the first sealing portion 31 protrudes from the outer peripheral wall of the main body portion 33 towards the first interface portion 11, the first sealing portion 31 abuts against the inner peripheral wall of the first interface portion 11, the second sealing portion 32 protrudes from the inner peripheral wall of the main body portion 33 towards the second interface portion 21, the second sealing portion 32 abuts against the outer peripheral wall of the second interface portion 21. Of course, it is also possible that the first sealing portion 31 and the second sealing portion 32 respectively abut against the outer peripheral wall of the first interface portion 11 and the outer peripheral wall of the second interface portion 21, which will not be elaborated here. In the above four embodiments, when a large positional deviation occurs between the first interface portion 11 and the second interface portion 21, the entire seal 3 can deflect along with the deviation direction of the two interface portions, so that the two sealing portions can still relatively abut against the two interface portions, ensuring the sealing effectiveness between the interface portions of the thermal management component.

[0022] Furthermore, in order to ensure that the compression amounts of the first sealing portion 31 and the second sealing portion 32 do not decrease significantly after the two interface portions deviate. Refer to Figure 4, at least one of the first sealing portion 31 and the second sealing portion 32 includes a first sealing end 301 and a second sealing end 302. Along the axial direction of the channel 30, for an embodiment in which one of the two sealing portions includes a first sealing end 301 and a second sealing end 302, the first sealing portion 31 or the second sealing portion 32 extends from the first sealing end 301 to the second sealing end 302. For an embodiment in which both of the two sealing portions include a first sealing end 301 and a second sealing end 302, both the first sealing portion 31 and the second sealing portion 32 extend from the first sealing end 301 to the second sealing end 302. In the same sealing portion, the first sealing end 301 is closer to the port of the channel 30 than the second sealing end 302. In other words, the first sealing end 301 is closer to the port of the channel 30 than the second sealing end 302 adjacent thereto. Define the circumferential wall radius dimension of the sealing portion away from the main body portion 33 as D, and define the circumferential wall radius of the interface portion in contact with the sealing portion close to the sealing portion as d. In the same sealing portion, the distance between the first sealing end 301 and the second sealing end 302 is L, and L is greater than the difference between D and d, where the difference between D and d is equivalent to the compression amount when the sealing portion abuts against the interface portion. Refer to Figure 4 , referring to the above-described four embodiments of the seal, D can be the outer circumferential wall radius of the sealing portion, and the corresponding d is the inner circumferential wall radius of the interface portion. The difference between D and d is the compression amount of the sealing portion against the inner circumferential wall of the interface portion. D can also be the inner circumferential wall radius of the sealing portion, and the corresponding d is the outer circumferential wall radius of the interface portion. The difference between D and d is the compression amount of the sealing portion against the outer circumferential wall of the interface portion. When L is greater than the difference between D and d, when the sealing portion deflects, the compression amount of the sealing portion will increase. As Figure 9 shown, in the vertical direction of this section, the maximum distance between the wall of the first sealing end 301 and the wall of the second sealing end 302 of the first sealing portion 31 will be greater than the outer diameter of the first sealing portion 31. Similarly, the same is true for the second sealing portion 32. This can ensure that after the two interface portions deviate, the first sealing portion 31 and the second sealing portion 32 follow the deflection, and the sealing portion will not leak due to the decrease in the compression amount.

[0023] Further, in order to ensure that the first sealing portion 31 and the second sealing portion 32 can deflect greatly and are not affected by the end of the main body portion 33, it is preferably to arrange the first sealing portion 31 and the second sealing portion 32 at relatively far positions at both ends of the main body portion 33, as Figure 4 and Figure 5 shown, both the first sealing portion 31 and the second sealing portion 32 are integrally structured with the main body portion 33. The seal 3 has an end wall portion 300. The port of the channel 30 is located at the end wall portion 300, and the first sealing end 301 is located at the end wall portion 300.

[0024] In some embodiments of the present application, refer to Figure 6, To better ensure the effectiveness of the seal, at least one of the first sealing portion 31 and the second sealing portion 32 includes a first convex portion 311 and a second convex portion 312. Both the first convex portion 311 and the second convex portion 312 form a closed-loop raised structure around the channel 30. The first convex portion 311 and the second convex portion 312 are arranged along the axial direction of the channel 30. The first convex portion 311 is closer to the port of the channel 30 than the second convex portion 312. The first sealing end 301 is located on the side of the first convex portion 311 away from the second convex portion 312, and the second sealing end 302 is located on the side of the second convex portion 312 away from the first convex portion 311. Along the axis direction of the channel 30, the first convex portion 311 is in contact with the second convex portion 312. Of course, due to deflection or manufacturing errors, there may be a gap between the first convex portion 311 and the second convex portion 312. A smaller gap does not affect the sealing effect of this embodiment. Both the first convex portion 311 and the second convex portion 312 abut against the first interface portion 11 or the second interface portion 21. Specifically, referring to Figure 10 , in this embodiment, the first convex portion 311 plays a major sealing role. When the entire seal 3 deflects, the compression amount of a part of the first convex portion 311 decreases, that is, the compression amount of the first convex portion 311 in the lower left corner and the upper right corner in the figure decreases, and the compression amount of the corresponding second convex portion 312 will increase. The second convex portion 312 will squeeze the first convex portion 311, causing the first convex portion 311 to deflect towards the first sealing end 301 to a certain extent, enabling the first convex portion 311 to further abut against the inner peripheral wall of the interface portion and avoiding leakage caused by insufficient compression amount.

[0025] Furthermore, referring to Figure 8 and Figure 11, in order to enable the seal 3 to adapt to a greater deflection, in this embodiment, the first sealing portion 31 and the second sealing portion 32 further include a connecting portion 313. The connecting portion 313 is located on the outer peripheral wall of the main body portion 33 and extends along the axial direction of the channel 30. The connecting portion 313 forms a closed-loop convex structure around the outer peripheral wall of the main body portion 33. The connecting portion 313 connects the first convex portion 311 and the second convex portion 312. The outer peripheral wall of the connecting portion 313 fits with the inner peripheral wall of the corresponding interface portion. Of course, due to deflection or manufacturing errors, there may be a gap between the first convex portion 311 and the second convex portion 312. A smaller gap does not affect the sealing effect of this embodiment. The outer peripheral wall of the connecting portion 313 fits with the inner peripheral wall of the interface portion to ensure that when the seal 3 deflects, the coolant leaks from the place where the compression amount of the first convex portion 311 is smaller, and the coolant does not flow in the annular space between the first convex portion 311 and the second convex portion 312. Of course, if there is a small gap between the outer peripheral wall of the connecting portion 313 and the inner peripheral wall of the interface portion in the non-deflected state, this gap will also be closed after deflection, so the coolant will not flow in this gap either. Preferably, the mating relationship between the outer peripheral wall of the connecting portion 313 and the inner peripheral wall of the interface portion is an interference fit. In this embodiment, on the one hand, dividing the seal into two convex portions can save materials and ensure that in the normal state, the two convex portions are repeatedly compressed. On the other hand, the connecting portion 313 can increase the distance between the first convex portion 311 and the second convex portion 312, so that the seal 3 can adapt to a greater deflection and the compression amount will not decrease significantly.

[0026] On the basis of the above embodiment, in order to ensure that the seal 3 can be smoothly assembled into the two interface portions, refer to Figures 5 - 8 , the seal 3 includes a support body 34. The support body 34 is arranged circumferentially around the channel 30. The main body portion 33 includes a covering portion 35. The covering portion 35 covers the support body 34. The first sealing portion 31 and the second sealing portion 32 are of an integral structure with the covering portion 35. The first sealing portion 31 extends radially along the channel 30 from the covering portion 35, and the second sealing portion 32 extends radially along the channel 30 from the covering portion 35. In this embodiment, the covering portion 35 and the sealing portion are both made of elastic rubber material. The specific material can refer to the current rubber sealing ring. The support body 34 is made of a material with a hardness greater than that of the rubber, which can be a metal material, preferably plastic. The rubber is vulcanized and coated around the plastic pipe. The support body 34 plays a supporting role during the assembly of the seal 3, avoiding deformation and improper assembly of the seal 3 made of pure rubber material during assembly. In addition, the support body 34 is embedded in the rubber layer, which can improve the degree to which the seal 3 can withstand the pressure of the coolant during operation.

[0027] Furthermore, refer to Figures 5 - 8, in order to ensure that the two sealing parts will not be deformed due to pressure during assembly, the support body 34 includes a base body, a first support part 341 and a second support part 342. Along the axial direction of the channel 30, the first support part 341 and the second support part 342 are respectively located at both ends of the base body. The first support part 341 extends from the base body along the radial direction of the channel 30 to the first sealing part 31, and the second support part 342 extends from the base body along the radial direction of the channel 30 to the second sealing part 32. Specifically, in this embodiment, the first support part 341 extends from the outer peripheral wall of the base body along the radial direction of the channel 30 to the first sealing part 31, and the second support part 342 extends from the outer peripheral wall of the base body along the radial direction of the channel 30 to the second sealing part 32. In this embodiment, the first support part 341 and the second support part 342 respectively play a certain supporting role for the first sealing part 31 and the second sealing part 32, preventing the two sealing parts from being deformed during assembly, resulting in poor sealing effect. In addition, the first support part 341 and the second support part 342 also have the function of controlling the compression amount of the two sealing parts, preventing insufficient and excessive compression amounts, and avoiding poor sealing effect.

[0028] Further, in this embodiment, on the basis of the above embodiment having the first convex part 311 and the second convex part 312, the support part is provided to only support the first convex part 311 that plays the main sealing function, and to control the compression amount of the first convex part 311. The second convex part 312 that plays the auxiliary sealing function is not supported, which is beneficial to the deformation of the second convex part 312 to squeeze the first convex part 311. In addition, the first convex part 311 is located at both ends. As long as the first convex part 311 is not easily deformed during assembly, the second convex part 312 located at the relatively middle position is also not easily deformed. Specifically, referring to Figures 6 - 8 , both the first sealing part 31 and the second sealing part 32 include a first convex part 311 and a second convex part 312. The first support part 341 extends from the outer peripheral wall of the base body to the first convex part 311 of the first sealing part 31, and the second support part 342 extends from the outer peripheral wall of the base body to the first convex part 311 of the second sealing part 32.

[0029] In this embodiment, the seal 3 of the above embodiment is mainly applied to achieve sealing between the two runner plate interface parts. In particular, for the sealing of the runner plate interface part formed by stamping on one side, due to the limitations of the process during stamping of the stamped runner plate, certain errors will occur. In addition, during the welding process of the two stamped runner plates, the stress change caused by welding will also cause the plate parts to warp and deform, resulting in further deviation of the positions between the two interface parts, making the traditional radial sealing and end face sealing methods no longer suitable. Therefore, in this embodiment, the thermal management component includes a first plate body 1 and a second plate body 2. The first interface part 11 is fixedly connected or integrally structured with the first plate body 1, and the second interface part 21 is fixedly connected or integrally structured with the second plate body 2. The first interface part 11 protrudes towards the second plate body 2 relative to the first plate body 1, and the second interface part 21 protrudes towards the first plate body 1 relative to the second plate body 2. At least part of the first plate body 1 is made of plastic, and the second plate body 2 is formed by stamping. The seal 3 can play a role in the above application scenarios.

[0030] Some measures can be taken to relatively reduce the position deviation between the first interface part 11 and the second interface part 21. Refer to Figure 12 , the thermal management component includes a support part 12. The support part 12 protrudes towards the second plate body 2 relative to the first plate body 1. The support part 12 is integrally structured with the first interface part 11. The support, the first interface part 11, and the runner plate body can be integrally formed by injection molding. To facilitate the installation of the seal 3, a diameter-expanded section 212 can be provided in at least one of the first interface part 11 and the second interface part 21. In this embodiment, since it is inconvenient to demold the Y-shaped diameter-expanded section 212 on the plastic part, while in the metal part, it is convenient to stamp and expand the diameter or machine the diameter-expanded section 212 on the rotating part. Therefore, the second interface part 21 includes a sealing section 211 and a diameter-expanded section 212. The sealing section 211 and the diameter-expanded section 212 are integrally structured. The second sealing part 32 abuts against the inner peripheral wall of the sealing section 211. The diameter-expanded section 212 is relatively far from the second plate body 2 compared to the sealing section 211. Along the axial direction of the second accommodation cavity 210, the diameter-expanded section 212 expands from the sealing section 211 towards the first interface part 11. Therefore, in this embodiment, the seal 3 can be first assembled to the first interface part 11, and then the second plate body 2 is installed, that is, the second plate body 2 is threadedly connected to the support part 12, and at the same time, the seal 3 is inserted into the sealing section 211 from the diameter-expanded section 212.

[0031] It should be noted that the above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the technical field can still modify the present invention or make equivalent replacements. All technical solutions and their improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
