Description

Technical Field

[0001] This application relates to the field of thermal management technology, specifically to a cooling plate assembly and its manufacturing method. Background Technology

[0002] The connection between adjacent cooling plates is mainly achieved through the mating of sleeves and metal male connectors. The sleeves are sealed to the metal male connectors of different cooling plates on both sides. The metal male connectors and sleeves are sealed by sealing ribs. However, during the assembly process, the sealing ribs can experience uncontrolled displacement and deformation, thus affecting the sealing reliability. Summary of the Invention

[0003] The purpose of this application is to provide a cooling plate assembly and manufacturing method that improves sealing reliability.

[0004] One embodiment of this application provides a cooling plate assembly, including at least one first connecting portion, at least one second connecting portion mating portion, and at least one first sealing portion. Along the radial direction of the first connecting portion, for both the inner and outer circumferential surfaces of the first connecting portion, a circumferential surface of the first connecting portion relatively close to the first mating portion is defined as a first circumferential surface. Along the radial direction of the first connecting portion, for both the inner and outer circumferential surfaces of the first mating portion, a circumferential surface of the first mating portion relatively close to the first connecting portion is defined as a second circumferential surface. The first circumferential surface is sealingly connected to the first sealing portion, and the second circumferential surface is sealingly connected to the first sealing portion. The cooling plate assembly includes at least one first rib, which is connected to the first connecting portion and / or the first mating portion. The first rib abuts against the first sealing portion, or, along the axial direction of the first connecting portion, a gap exists between the first rib and the first sealing portion.

[0005] In the above technical solution, the cooling plate assembly includes a first rib, which is connected to the first connecting part and / or the first mating part. The first rib also abuts against the first sealing part. Alternatively, along the axial direction of the first connecting part, there is a gap between the first rib and the first sealing part. Therefore, along the axial direction of the first connecting part, the first rib limits the maximum deformation of the first sealing part, reduces the probability of sealing failure caused by excessive deformation of the first sealing part, and thus improves the sealing reliability of the first sealing part.

[0006] This application also provides a method for manufacturing a cooling plate assembly, which involves fabricating a first connecting portion and a first mating portion; wherein the above steps include forming a first sealing portion and a first rib portion in at least one of the first connecting portion and the first mating portion, wherein the first sealing portion is closer to the central axis of the first connecting portion than the first rib portion, and the first sealing portion and the first rib portion are spaced apart axially in the first connecting portion;

[0007] Assemble the first connecting part and the first mating part.

[0008] In the above technical solution, the manufacturing method of the cooling plate assembly forms a first sealing part and a first rib in at least one of the first connecting part and the first mating part. The first sealing part and the first rib are spaced apart axially in the first connecting part. Therefore, when the first sealing part deforms, the first rib limits the maximum deformation of the first sealing part along the axial direction of the first connecting part, reducing the probability of sealing failure caused by excessive deformation of the first sealing part, thereby improving the sealing reliability of the first sealing part. Furthermore, because the first sealing part is closer to the central axis of the first connecting part than the first rib, the friction between the first rib and the first connecting part or the first mating part is reduced, reducing the risk of deformation during assembly of the first connecting part and the first mating part, thereby improving the sealing reliability.

[0043] Specific embodiments will now be described in detail with reference to the accompanying drawings. Numerous specific details are set forth in the following detailed description in order to provide a full understanding of the invention; however, those skilled in the art will understand that the specific components, devices, and features illustrated in the drawings and described herein are merely exemplary and should not be considered limiting.

[0044] like Figures 1-32As shown, the cooling plate assembly includes a first cooling plate 11, a second cooling plate 12, and a first connecting portion 13. Both the first cooling plate 11 and the second cooling plate 12 include a first mating portion 14. One first connecting portion 13 is assembled with two first mating portions 14. The first connecting portion 13 has a first flow portion 131, and the first mating portions 14 have second flow portions 141. The first flow portions 131 and the second flow portions 141 communicate. The medium within the first cooling plate 11 flows to the second flow portion 141, which communicates with the first cooling plate 11. Because the first connecting portion 13 is assembled with two first mating portions 14, the medium within the first mating portion 14, which communicates with the first cooling plate 11, flows into the first connecting portion 13, then into the first mating portion 14, which communicates with the second cooling plate 12, and then into the second cooling plate 12. In other embodiments, it can also be as follows... Figure 32 As shown, the cooling plate assembly includes a second cooling plate 12 and a first connecting portion 13. The second cooling plate 12 includes a first mating portion 14, and the first connecting portion 13 is assembled with the first mating portion 14.

[0045] like Figures 1-32As shown, the cooling plate assembly includes at least one first connecting portion 13, at least one first mating portion 14, and at least one first sealing portion 15. The first flow portion 131 communicates with the second flow portion 141 and is sealed by the first sealing portion 15. Along the radial direction of the first connecting portion 13, for both the inner and outer circumferential surfaces of the first connecting portion 13, the circumferential surface of the first connecting portion 13 that is relatively close to the first mating portion 14 is defined as the first circumferential surface 132. Similarly, along the radial direction of the first connecting portion 13, for both the inner and outer circumferential surfaces of the first mating portion 14, the circumferential surface of the first mating portion 14 that is relatively close to the first connecting portion 13 is defined as... The second circumferential surface 142 is sealed to the first circumferential surface 132 and the first sealing part 15, thereby sealing the first flow part 131 and the second flow part 141, preventing fluid from flowing outside the cooling plate assembly. The cooling plate assembly includes a first rib 16, which is connected to the first connecting part 13 and abuts against the first sealing part 15. Therefore, along the axial direction of the first connecting part 13, the first rib 16 limits the maximum deformation of the first sealing part 15, reducing the likelihood of seal failure due to excessive deformation of the first sealing part 15. This improves the sealing reliability of the first sealing part 15. In this embodiment, the first rib 16 and the first connecting part 13 are integrally formed, limiting the maximum deformation of the first rib 16 and thus reducing the probability of sealing failure caused by excessive deformation of the first sealing part 15, thereby improving the sealing reliability of the first sealing part 15. Of course, the first rib 16 can also be integrally formed with the first mating part 14, or the first rib 16 can be integrally formed with one of the first connecting part 13 and the first mating part 14 while being sealed to the other. In other embodiments, it can also be along the first... In the axial direction of the connecting portion 13, there is a gap between the first rib portion 16 and the first sealing portion 15. It should be noted that in this embodiment, since the deformation of the first sealing portion 15 is small, the first sealing portion 15 and the first rib portion 16 do not contact each other. However, since there is a gap between the first rib portion 16 and the first sealing portion 15 in the axial direction of the first connecting portion 13, the first rib portion 16 can limit the maximum deformation of the first sealing portion 15 in the axial direction of the first connecting portion 13, reducing the probability of sealing failure caused by excessive deformation of the first sealing portion 15, thereby improving the sealing reliability of the first sealing portion 15.

[0046] A method for manufacturing a cooling plate assembly is also provided, comprising fabricating a first connecting portion 13 and a first mating portion 14; wherein the above steps include forming a first sealing portion 15 and a first rib portion 16 in at least one of the first connecting portion 13 and the first mating portion 14, that is, the first sealing portion 15 and the first rib portion 16 can be formed in the first connecting portion 13 or in the first mating portion 14, the first sealing portion 15 being closer to the central axis of the first connecting portion 13 than the first rib portion 16, the first sealing portion 15 and the first rib portion 16 being spaced axially apart in the first connecting portion 13, and assembling the first connecting portion 13 and the first mating portion 14.

[0047] When assembling the first connecting part 13 and the first mating part 14, since the first sealing part 15 is closer to the central axis of the first connecting part 13 than the first rib 16, the friction between the first rib 16 and the first connecting part 13 or the first mating part 14 is reduced.

[0048] Furthermore, the compression ratio of the first sealing part 15 is between 15% and 55%, which reduces the problem of excessive deformation of the first sealing part 15 due to excessive compression ratio, thereby reducing the sealing reliability.

[0049] This application focuses on improving the structure of the first connecting part 13 and the first mating part 14, which will be described in detail below with reference to the accompanying drawings.

[0050] Example 1

[0051] Please refer to Figure 1 , Figure 4 , Figure 5 , Figures 9-11 The first embodiment shown specifically discloses that the first sealing part 15 is connected to the first connecting part 13, and the first rib 16 is connected to the first connecting part 13. It should be noted that in this embodiment, the first sealing part 15 and the first connecting part 13 are an integral structure, and the first rib 16 and the first connecting part 13 are also an integral structure, satisfying the requirement that the first sealing part 15 and the first connecting part 13 are connected, and the first rib 16 and the first connecting part 13 are also connected. In other embodiments, such as... Figure 4 , Figure 5As shown, the first sealing part 15 and the first rib 16 can be an integral structure, or the integral structure of the first sealing part 15 and the first rib 16 and the first connecting part 13 can be a separate structure. Alternatively, the first sealing part 15, the first rib 16, and the first connecting part 13 can all be separate structures, satisfying the following: the first sealing part 15 seals the first circumferential surface 132 of the first connecting part 13, and the first sealing part 15 seals the second circumferential surface 142 of the first mating part 14. Along the axial direction of the first connecting part 13, the first connecting part 13 has a first end 133, and the first sealing part 15 is closer to the first end 133 than the first rib 16. Along the radial direction of the first connecting part 13, the first connecting part 13 is located on the outer periphery of the first mating part 14. The sealing portion 15 and the first rib portion 16 protrude relative to the first circumferential surface 132. Because the first sealing portion 15 protrudes relative to the first circumferential surface 132, when the first connecting portion 13 is assembled with the first mating portion 14, the first sealing portion 15 undergoes displacement deformation under the action of friction between the first sealing portion 15 and the first mating portion 14. Therefore, the structure of the first rib portion 16 protruding relative to the first circumferential surface 132 can limit the maximum deformation of the first sealing portion 15 along the axial direction of the first connecting portion 13, reducing the probability of sealing failure caused by excessive deformation of the first sealing portion 15, thereby improving the sealing reliability of the first sealing portion 15. In this embodiment, the first connecting portion 13 includes a first section 137 and a second section 138. Part 137 is assembled with the first mating part 14 of the first cooling plate 11, and the second section 138 is assembled with the first mating part 14 of the second cooling plate 12. The first connecting part 13 includes two first end portions 133, which are located at the first section 137 and the second section 138, respectively. The first sealing part 15 includes a first sub-sealing part 151 and a second sub-sealing part 152. The first rib part 16 includes a first sub-rib part 161 and a second sub-rib part 162. The second sub-sealing part 152 is integrally formed with the first section 137, the second sub-rib part 162 is integrally formed with the first section 137, the first sub-sealing part 151 is integrally formed with the second section 138, and the first sub-rib part 161 is integrally formed with the second section 138. In the axial direction of the first connecting portion 13, the first sub-sealing portion 151 is closer to the second cooling plate 12 than the first sub-rib portion 161, and the second sub-sealing portion 152 is closer to the first cooling plate 11 than the second sub-rib portion 162. The first sub-sealing portion 151 abuts against the first sub-rib portion 161, and the second sub-sealing portion 152 abuts against the second sub-rib portion 162. The first sub-rib portion 161 limits the maximum deformation of the first sub-sealing portion 151, and the second sub-rib portion 162 limits the maximum deformation of the second sub-sealing portion 152. This reduces the probability of seal failure caused by excessive deformation of the first sub-sealing portion 151 and the second sub-rib portion 162, thereby improving the sealing reliability of the first sub-sealing portion 151 and the second sub-rib portion 162. It should be noted that in this embodiment...The first connecting portion 13 is assembled with two first mating portions 14. The first connecting portion 13 includes two first end portions 133. Therefore, in this embodiment, the first sealing portion 15 is closer to the first end portion 133 relative to the first rib portion 16, or the first rib portion 16 is closer to the first end portion 133 relative to the first sealing portion 15. Here, the first sealing portion 15 and the first rib portion 16 refer to the first sub-sealing portion 151 and the first sub-rib portion 161, the second sub-sealing portion 152 and the second sub-rib portion 162. That is, when the first sealing portion 15 represents the first sub-sealing portion 151, the first rib portion 16 represents the first sub-rib portion 161; when the first sealing portion 15 represents the second sub-sealing portion 152, the first rib portion 16 represents the second sub-rib portion 162. Only when the first sealing portion 15 protrudes relative to the first circumferential surface 132, therefore the first sealing portion 151 is closer to the first end portion 133. The sealing portion 15 connects to the second circumferential surface 142, thereby sealing the first sealing portion 15 with the second circumferential surface 142. Therefore, the resistance encountered during assembly of the first connecting portion 13 and the first mating portion 14 includes the frictional force between the first sealing portion 15 and the second circumferential surface 142. Compared to the scheme where the first circumferential surface 132 contacts and then seals with the second circumferential surface 142, since the contact area between the first sealing portion 15 and the second circumferential surface 142 is smaller than that between the first circumferential surface 132 and the second circumferential surface 142, the contact area with the second circumferential surface 142 is reduced by using the first sealing portion 15 instead of the first circumferential surface 132. This reduces the resistance encountered during assembly of the first connecting portion 13 and the first mating portion 14, and lowers the risk of deformation during assembly.

[0052] Regarding the manufacturing method of the cooling plate assembly, before the first connecting part 13 and the first mating part 14 are assembled, along the radial direction of the first connecting part 13, the protrusion distance of the first sealing part 15 relative to the first circumferential surface 132 is a first distance D1, and the protrusion distance of the first rib 16 relative to the first circumferential surface 132 is a second distance D2. The first distance D1 is greater than the second distance D2. Since the protrusion distance of the first rib 16 is lower than the protrusion distance of the first sealing part 15, the friction between the first rib 16 and the second circumferential surface 142 is reduced, thereby reducing the resistance experienced by the first connecting part 13 and the first mating part 14 during the assembly process. Furthermore, because the first rib 16 is protruding, it plays a guiding role for the first mating part 14, reducing the probability of tearing of the first circumferential surface 132 caused by excessive local interference due to positional deviation during the assembly of the first mating part 14 and the first connecting part 13.

[0053] Example 2

[0054] Please refer to Figures 1-8The second embodiment shown differs from the first embodiment in that, along the axial direction of the first connecting portion 13, the first rib 16 is closer to the first end 133 relative to the first sealing portion 15. The first sealing portion 15 and the first rib 16 protrude relative to the first circumferential surface 132. Because the first sealing portion 15 protrudes relative to the first circumferential surface 132, the first connecting portion 13 is assembled with the first mating portion 14. Due to the friction between the first sealing portion 15 and the first mating portion 14, the first sealing portion 15 undergoes displacement deformation. Therefore, the first rib 16 protrudes relative to the first circumferential surface 132. Along the axial direction of the first connecting portion 13, the first rib 16 restricts the maximum deformation of the first sealing portion 15, reducing the probability of seal failure caused by excessive deformation of the first sealing portion 15. To improve the sealing reliability of the first sealing portion 15, in this embodiment, along the axial direction of the first connecting portion 13, the first sub-rib portion 161 is closer to the second cooling plate 12 relative to the first sub-sealing portion 151, and the second sub-rib portion 162 is closer to the first cooling plate 11 relative to the second sub-sealing portion 152. The first sub-sealing portion 151 abuts against the first sub-rib portion 161, and the second sub-sealing portion 152 abuts against the second sub-rib portion 162. The first sub-rib portion 161 limits the maximum deformation of the first sub-sealing portion 151, and the second sub-rib portion 162 limits the maximum deformation of the second sub-sealing portion 152, thereby reducing the probability of sealing failure caused by excessive deformation of the first sub-sealing portion 151 and the second sub-rib portion 162, and thus improving the sealing reliability of the first sub-sealing portion 151 and the second sub-rib portion 162.

[0055] Regarding the manufacturing method of the cooling plate assembly, before the first connecting part 13 and the first mating part 14 are assembled, along the radial direction of the first connecting part 13, the protrusion distance of the first sealing part 15 relative to the first circumferential surface 132 is a first distance D1, and the protrusion distance of the first rib 16 relative to the first circumferential surface 132 is a second distance D2. The first distance D1 is not less than the second distance D2. Since the protrusion distance of the first sealing part 15 is not less than the protrusion distance of the first rib 16, the friction between the first rib 16 and the second circumferential surface 142 is reduced, thereby reducing the resistance received by the first connecting part 13 and the first mating part 14 during the assembly process. Because the first connecting part 13 and the first mating part 14 are assembled, the first sealing part 15 along the first end 13... The displacement deformation in the direction of the center line 134 weakens the ability of the first sealing part 15 to withstand negative pressure. It should be noted that the negative pressure here refers to the situation where the fluid pressure is lower than the external atmospheric pressure when the fluid flows in the first flow part 131 and the second flow part 141. At this time, the pressure generated by the external atmospheric pressure on the first sealing part 15 at the sealing part of the first connecting part 13 and the first mating part 14 is the negative pressure. The direction of the negative pressure is along the first end 133 towards the center line 134. Since the first rib 16 supports the first sealing part 15, the first rib 16 improves the ability of the first sealing part 15 to withstand negative pressure, thereby improving the sealing reliability of the first sealing part 15.

[0056] Example 3

[0057] Please refer to Figure 1 , Figure 4 , Figure 5 , Figures 12-17The third embodiment shown is based on the first embodiment and specifically discloses a cooling plate assembly including a second rib 17, which is connected to a first connecting portion 13. It should be noted that in this embodiment, the second rib 17 and the first connecting portion 13 are an integral structure, satisfying the requirement of connection between the second rib 17 and the first connecting portion 13. In other embodiments, the second rib 17, the first rib 16, and the first sealing portion 15 may be an integral structure, while the integral structure of the second rib 17, the first rib 16, and the first sealing portion 15 and the first connecting portion 13 may be separate structures. The second rib 17 protrudes relative to the first circumferential surface 132 and extends along the first connecting portion 13. In the axial direction of 3, the second rib 17 is located on one side of the first sealing part 15, and the first rib 16 is located on the other side of the first sealing part 15. Since the second rib 17 protrudes relative to the first circumferential surface 132, and the first sealing part 15 is closer to the first end 133 relative to the first rib 16, and the second rib 17 is located on the other side of the first sealing part 15, the second rib 17 is closer to the first end 133 relative to the first sealing part 15. The second rib 17 plays a guiding role for the first mating part 14, reducing the probability of tearing of the first circumferential surface 132 caused by excessive local interference due to positional deviation when the first mating part 14 and the first connecting part 13 are assembled.

[0058] Regarding the manufacturing method of the cooling plate assembly, before the first connecting part 13 and the first mating part 14 are assembled, the second rib 17 protrudes a third distance D3 relative to the first circumferential surface 132 along the radial direction of the first connecting part 13. The third distance D3 is less than the first distance D1. Since the protrusion distance of the second rib 17 is less than that of the first sealing part 15, the friction between the second rib 17 and the second circumferential surface 142 is reduced, thereby reducing the resistance experienced by the first connecting part 13 and the first mating part 14 during the assembly process.

[0059] Furthermore, the second rib 17 is connected to the second circumferential surface 142. Since the second rib 17 is closer to the first end 133 than the first sealing part 15, and the second rib 17 is connected to the second circumferential surface 142, the second rib 17 acts as a shield for the first sealing part 15, reducing the probability of impurities intruding into the first sealing part 15, thereby improving the sealing reliability of the first sealing part 15.

[0060] Regarding the manufacturing method of the cooling plate assembly, before the first connecting part 13 and the first mating part 14 are assembled, along the axial direction of the first connecting part 13, the end of the second rib 17 near the first end 133 is defined as the first sub-part 171. The second rib 17 includes the second sub-part 172. Before the first connecting part 13 and the first mating part 14 are assembled, along the radial direction of the first connecting part 13, the protrusion distance of the first sub-part 171 relative to the first circumferential surface 132 is the fourth distance D4, and the protrusion distance of the second sub-part 172 relative to the first circumferential surface 132 is the fifth distance D5. The fourth distance D4 is smaller than the fifth distance D5. That is, for the second rib 17, the part near the first end 133 has a smaller protrusion distance relative to the first circumferential surface 132, thereby improving the guiding effect of the second rib 17 on the first mating part 14.

[0061] Example 4

[0062] Please refer to Figure 1 , Figure 4 , Figure 5 , Figures 18-21The fourth embodiment shown differs from the first embodiment in that the first sealing part 15 is connected to the first mating part 14, and the first rib 16 is also connected to the first mating part 14. It should be noted that in this embodiment, the first sealing part 15 and the first mating part 14 are an integral structure, and the first rib 16 and the first mating part 14 are also an integral structure, satisfying the requirement that the first sealing part 15 and the first mating part 14 are connected. In other embodiments, the first sealing part 15 and the first rib 16 may be an integral structure, while the integral structure of the first sealing part 15 and the first rib 16 and the first mating part 14 may be a separate structure, satisfying the requirement that the first sealing part 15 and the first rib 16 are connected. The first sealing portion 15 is sealed to the first peripheral surface 132 of the first connecting portion 13, and the first sealing portion 15 is sealed to the second peripheral surface 142 of the first mating portion 14. Along the axial direction of the first connecting portion 13 and the first mating portion 14, the second end 143 is defined as the end of the first mating portion 14 that is relatively close to the first connecting portion 13. Along the axial direction of the first mating portion 14, the first rib 16 is closer to the second end 143 relative to the first sealing portion 15. Along the radial direction of the first mating portion 14, the first mating portion 14 is located on the inner periphery of the first connecting portion 13. Along the radial direction of the first mating portion 14, the first sealing portion 15 and the first rib 16 protrude relative to the second peripheral surface 142. Because the first sealing portion 15 is relative to... The second circumferential surface 142 protrudes, and the first connecting portion 13 is assembled with the first mating portion 14. Under the action of friction between the first sealing portion 15 and the first connecting portion 13, the first sealing portion 15 undergoes displacement deformation. Therefore, the first rib 16 protrudes relative to the second circumferential surface 142. The first rib 16 can limit the maximum deformation of the first sealing portion 15, reduce the probability of sealing failure caused by excessive deformation of the first sealing portion 15, and thus improve the sealing reliability of the first sealing portion 15. Since the first sealing portion 15 protrudes relative to the second circumferential surface 142, the first sealing portion 15 is connected to the first circumferential surface 132, and thus the first sealing portion 15 is sealed to the first circumferential surface 132. Therefore, the first connecting portion 142... The resistance encountered when assembling the first connecting part 13 with the first mating part 14 includes the frictional force between the first sealing part 15 and the first circumferential surface 132. Compared to the scheme where the first circumferential surface 132 contacts and seals with the second circumferential surface 142, since the contact area between the first sealing part 15 and the first circumferential surface 132 is smaller than the contact area between the first circumferential surface 132 and the second circumferential surface 142, the contact area with the first circumferential surface 132 is reduced by replacing the second circumferential surface 142 with the first circumferential surface 132. This reduces the resistance encountered when assembling the first connecting part 13 with the first mating part 14, and lowers the risk of deformation when assembling the first connecting part 13 and the first mating part 14.

[0063] Regarding the manufacturing method of the cooling plate assembly, before the first connecting part 13 and the first mating part 14 are assembled, along the radial direction of the first mating part 14, the protrusion distance of the first sealing part 15 relative to the second peripheral surface 142 is a sixth distance D6, and the protrusion distance of the first rib 16 relative to the second peripheral surface 142 is a seventh distance D7. The sixth distance D6 is greater than the seventh distance D7. Since the protrusion distance of the first rib 16 is lower than the protrusion distance of the first sealing part 15, the friction between the first rib 16 and the first peripheral surface 132 is reduced, thereby reducing the resistance experienced by the first connecting part 13 and the first mating part 14 during the assembly process. Furthermore, because the first rib 16 is protruding, it plays a guiding role for the first mating part 14, reducing the probability of tearing of the second peripheral surface 142 caused by excessive local interference due to positional deviation during the assembly of the first mating part 14 and the first connecting part 13.

[0064] Example 5

[0065] Please refer to Figure 1 , Figure 4 , Figure 5 , Figure 18 , Figure 19 , Figures 22-23The fifth embodiment shown differs from embodiment four in that, along the axial direction of the first mating portion 14, the first sealing portion 15 is closer to the second end 143 relative to the first rib portion 16. Along the radial direction of the first mating portion 14, the first sealing portion 15 and the first rib portion 16 protrude relative to the second circumferential surface 142. Because the first sealing portion 15 protrudes relative to the second circumferential surface 142, the first connecting portion 13 is assembled with the first mating portion 14. Under the frictional force between the first sealing portion 15 and the first connecting portion 13, the first sealing portion 15 undergoes displacement and deformation. Therefore, the first... The rib 16 protrudes relative to the second circumferential surface 142. The first rib 16 can limit the maximum deformation of the first sealing part 15, reduce the probability of seal failure caused by excessive deformation of the first sealing part 15, and thus improve the sealing reliability of the first sealing part 15. Before the first connecting part 13 and the first mating part 14 are assembled, along the radial direction of the first mating part 14, the protrusion distance of the first sealing part 15 relative to the second circumferential surface 142 is the sixth distance D6, and the protrusion distance of the first rib 16 relative to the second circumferential surface 142 is the seventh distance D7. The sixth distance D6 is not less than the seventh distance D7. At a distance of D7, since the protrusion distance of the first sealing part 15 is not less than the protrusion distance of the first rib 16, the friction between the first rib 16 and the first circumferential surface 132 is reduced, thereby reducing the resistance experienced by the first connecting part 13 and the first mating part 14 during assembly. Because the first sealing part 15 deforms in the axial direction of the first mating part 14 during assembly of the first connecting part 13 and the first mating part 14, the first sealing part 15 is weakened in its ability to withstand negative pressure. It should be noted that the negative pressure here refers to the pressure exerted by the fluid on the first... When the fluid flows in the flow section 131 and the second flow section 141, there is a situation where the pressure of the fluid is lower than the external atmospheric pressure. At this time, there is a negative pressure generated by the external atmospheric pressure on the sealing part of the first connection part 13 and the first mating part 14, namely the first sealing part 15. Since the first rib 16 can limit the maximum deformation of the first sealing part 15, the probability of sealing failure caused by excessive deformation of the first sealing part 15 is reduced, thereby improving the first sealing part 15's ability to withstand negative pressure and thus providing sealing reliability of the first sealing part 15.

[0066] Example 6

[0067] Please refer to Figure 1 , Figure 4 , Figure 5 , Figures 24-26The sixth embodiment shown is based on the previous embodiment and specifically discloses a cooling plate assembly including a second rib 17. The second rib 17 is connected to the first mating part 14. It should be noted that in this embodiment, the second rib 17 and the first mating part 14 are an integral structure to satisfy the connection between the second rib 17 and the first mating part 14. In other embodiments, the second rib 17, the first rib 16, and the first sealing part 15 can be an integral structure, while the integral structure of the second rib 17, the first rib 16, and the first sealing part 15 and the first mating part 14 can be a separate structure. The second rib 17 protrudes relative to the second peripheral surface 142 along the axial direction of the first mating part 14. The second rib 17 is located on one side of the first sealing part 15, and the first rib 16 is located on the other side of the first sealing part 15. Since the second rib 17 protrudes relative to the second peripheral surface 142, and the first sealing part 15 protrudes relative to the first rib 142, the second rib 17 is located on one side of the first sealing part 15, and the first rib 16 is located on the other side of the first sealing part 15. 16 is closer to the second end 143, and the second rib 17 is located on the other side of the first sealing part 15. Therefore, the second rib 17 is closer to the second end 143 than the first sealing part 15. The second rib 17 plays a guiding role for the first mating part 14, reducing the probability of tearing of the second circumferential surface 142 caused by excessive local interference due to positional deviation when the first mating part 14 is assembled with the first connecting part 13. Before the first connecting part 13 and the first mating part 14 are assembled, along the radial direction of the first mating part 14, the protrusion distance of the second rib 17 relative to the second circumferential surface 142 is the eighth distance D8, which is less than the sixth distance D6. Since the protrusion distance of the second rib 17 is less than that of the first sealing part 15, the friction between the second rib 17 and the second circumferential surface 142 is reduced, thereby reducing the resistance experienced by the first connecting part 13 and the first mating part 14 during the assembly process.

[0068] Furthermore, the second rib 17 is connected to the first circumferential surface 132. Since the second rib 17 is closer to the second end 143 than the first sealing part 15, and the second rib 17 is connected to the first circumferential surface 132, the second rib 17 acts as a shield for the first sealing part 15, reducing the probability of impurities intruding into the first sealing part 15, thereby improving the sealing reliability of the first sealing part 15.

[0069] Example 7

[0070] Please refer to Figure 27 , Figure 28 The seventh embodiment shown differs from the previous embodiments in that, along the radial direction of the first connecting portion 13, the first connecting portion 13 is located on the inner periphery of the first mating portion 14. Alternatively, along the radial direction of the first connecting portion 13, the first connecting portion 13 may be located on the outer periphery of one first mating portion 14 and on the inner periphery of another first mating portion 14.

[0071] Example 8

[0072] Please refer to Figure 29 The eighth embodiment shown is based on the above embodiments and specifically discloses a cooling plate assembly including a limiting part 18. Along the radial direction of the first connecting part 13, the limiting part 18 is connected to the first connecting part 13. Along the axial direction of the first mating part 14, the first connecting part 13 has a second end portion 143. Along the axial direction of the first mating part 14, the second end portion 143 is defined as the end of the first mating part 14 relatively close to the first connecting part 13. Along a plane perpendicular to the axial direction of the first connecting part 13, the orthographic projection of the limiting part 18 on the plane and the orthographic projection of the second end portion 143 on the plane are shown. Since the orthographic projection of the limiting part 18 on the plane and the orthographic projection of the second end 143 on the plane are at least partially overlapped, when the first connecting part 13 and the first mating part 14 are assembled, the limiting part 18 acts as a block against the first mating part 14 along the assembly direction of the first connecting part 13 and the first mating part 14, restricting the relative movement of the first connecting part 13 and the first mating part 14. The limiting part 18 acts as a block during assembly, limiting the maximum length of the assembled part of the first connecting part 13 and the first mating part 14, thereby playing a positioning role and reducing the difficulty of installation.

[0073] Example 9

[0074] Please refer to Figures 30-32 The ninth embodiment shown is based on the above embodiments and specifically discloses that the first connecting part 13 is formed by a two-color injection molding process. The first connecting part 13 includes a first layer 135 and a second layer 136. The first layer 135 is a plastic material, and the second layer 136 is an elastic material. In this embodiment, the first layer 135 is PA12 rigid plastic, and the second layer 136 is a thermoplastic elastomer material or liquid silicone material. The first layer 135 and the second layer 136 are fixedly connected. After being formed by the two-color injection molding process, the first layer 135 and the second layer 136 are fixedly connected by injection molding. After the first connecting part 13 is assembled with the first mating part 14, since the second layer 136 is a thermoplastic elastomer... The first connecting part 13 and the first mating part 14 are sealed by the compression deformation of the thermoplastic elastomer material or liquid silicone material. Since the first layer 135 is PA12 rigid plastic, it provides supporting stiffness, thereby reducing the stretching of the first sealing rib and enhancing the compression effect of the first sealing rib, thus enhancing the sealing performance. Furthermore, since the first layer 135 is located on the outer periphery of the second layer 136, after the two first mating parts 14 are assembled with the first connecting part 13, when there is a positional deviation along the assembly direction of the first connecting part 13 and the first mating part 14, the first connecting part tilts, and the first sealing rib and the first mating part 14 remain sealed, improving the sealing reliability.

[0075] Example 10

[0076] Please refer to Figures 1-32 The tenth embodiment shown is based on the above embodiments. Specifically, the contact pressure between the first sealing part 15 and the first mating part 14 or the first connecting part 13 is the first pressure, and the internal working pressure of the first connecting part 13 is the second pressure. Along the axial direction of the first connecting part 13, the width of the area where the first pressure is greater than the second pressure is not less than 0.6 mm. Along the direction perpendicular to the axial direction of the first connecting part 13, the positional difference between the axis of the first connecting part 13 and the axis of the first mating part 14 does not exceed 3 mm. After the first connecting part 13 and the first mating part 14 are assembled, the compression rate of the first sealing part 15 is between 15% and 55%, which reduces the probability of sealing failure between the first connecting part 13 and the first mating part 14, thereby improving the sealing reliability. The Shore hardness A of the second layer 136 is between 40 and 65. Since the first sealing part and the first rib are protruding, there is a certain difficulty in demolding. Controlling the Shore hardness A of the second layer 136 to be between 40 and 65 is beneficial to reduce the demolding difficulty.
