The cooling plate assembly includes a limiting portion 18. Along the assembly direction of the first matching portion 14 and the first connecting portion 13, the limiting portion 18 limits the relative movement of the first connecting portion 13 and the first matching portion 14. The limiting portion 18 plays a blocking role during assembly, limiting the maximum length of the assembly part of the first connecting portion 13 and the first matching portion 14, thereby playing a positioning role, reducing the difficulty of installation.

[0067] Example 2

[0068] Please refer to the second embodiment shown in Figures 1 to 6. This embodiment specifically discloses a cooling plate assembly, including a second cooling plate 12, a first cooling plate 11 and a first connecting portion 13.

The fluid flows from the first matching portion 14 of the second cooling plate 12 to the first connecting portion 13, and then flows to the first cooling plate 11 through the first matching portion 14 of the first cooling plate 11. The cooling plate assembly includes a limiting portion 18. Along the radial direction of the first connecting portion 13, the first connecting portion 13 is located at the outer periphery of the first matching portion 14. The limiting portion 18 is fixedly connected to the first connecting portion 13. It should be noted that the fixed The fixed connection may be an integral structure of the limiting portion 18 and the first connecting portion 13, for example, the limiting portion 18 is formed by the first connecting portion 13 being radially recessed along the first connecting portion 13, as shown in Figure 4, or the limiting portion 18 may be fixed to the first connecting portion 13 by processing, for example, the limiting portion 18 is fixedly connected to the first connecting portion 13 by welding, as shown in Figure 5, along the assembly direction of the first matching portion 14 and the first connecting portion 13, the limiting portion 18 abuts against the first matching portion 14, and the limiting portion 18 limits further relative movement of the first connecting portion 13 and the first matching portion 14, and the limiting portion 18 plays a blocking role during assembly, limiting the maximum length of the assembly part of the first connecting portion 13 and the first matching portion 14, thereby playing a positioning role, reducing the difficulty of installation.

[0069] In this solution, along the radial direction of the first connection part 13, the first connection part 13 is located at the outer periphery of the first matching part 14, the limiting part 18 is fixedly connected to the first connection part 13, and the limiting part 18 abuts against the first matching part 14; or, as shown in Figure 19, along the radial direction of the first connection part 13, the first connection part 13 is located at the outer periphery of the first matching part 14, the limiting part 18 is fixedly connected to the first matching part 14, and the limiting part 18 abuts against the first connection part 13; or, as shown in Figure 18, along the radial direction of the first connection part 13, the first matching part 14 is located at the outer periphery of the first connection part 13, the limiting part 18 is fixedly connected to the first connection part 13, and the limiting part 18 abuts against the first matching part 14; or, as shown in Figure 20, along the radial direction of the first connection part 13, the first matching part 14 is located at the outer periphery of the first connection part 13, the limiting part 18 is fixedly connected to the first matching part 14, and the limiting part 18 abuts against the first connection part 13.

[0070] Of course, it is also possible, as shown in FIG21 , that along the radial direction of the first connection portion 13, one side of the first connection portion 13 is located at the outer periphery of the first matching portion 14 of the second cooling plate 12, and the other side of the first connection portion 13 is located at the inner periphery of the first matching portion 14 of the first cooling plate 11, and the two limiting portions 18 are both fixedly connected to the first connection portion 13, and respectively abut against the first matching portion 14 of the second cooling plate 12 and the first matching portion 14 of the first cooling plate 11; or as shown in FIG22 , one limiting portion 18 is fixedly connected to the first connection portion 13 and abuts against the first matching portion 14 of the first cooling plate 11, and the other limiting portion 18 is fixedly connected to the first matching portion 14 of the second cooling plate 12 23, one limiting portion 18 is fixedly connected to the first matching portion 14 of the second cooling plate 12, and the other limiting portion 18 is fixedly connected to the first matching portion 14 of the first cooling plate 11, and the two limiting portions 18 respectively abut against the first connecting portion 13; or as shown in FIG24, one limiting portion 18 is fixedly connected to the first connecting portion 13 and abuts against the first matching portion 14 of the second cooling plate 12, and the other limiting portion 18 is fixedly connected to the first matching portion 14 of the first cooling plate 11 and abuts against the first connecting portion 13.

[0071] Example 3

[0072] 3 , this embodiment is based on the solution in which the first connection portion 13 is located on the periphery of the first matching portion 14 and the limiting portion 18 is fixedly connected to the first connection portion 13 in the previous embodiment. It specifically discloses that the number of the limiting portion 18 is one, the first connection portion 13 includes a connection portion 111, and the connection portion 111 includes a second segment 138 and a first segment 137. Along the extension direction of the first connection portion 13, the second segment 138 and the first segment 137 are respectively located on both sides of the limiting portion 18, the second segment 138 is sealedly connected to the first matching portion 14 of the second cooling plate 12, and the first segment 137 is sealedly connected to the first matching portion 14 of the first cooling plate 11. Along the extension direction of the first connection portion 13, the second segment 138 and the first segment 137 have the same length. In the extension direction of a connecting portion 13, the first matching portion 14 of the first cooling plate 11, the first matching portion 14 of the second cooling plate 12 and the connecting portion 111 have the same assembly length, thereby reducing the probability of one first matching portion 14 having a longer assembly length and thus causing another first matching portion 14 to have a shorter assembly length, thereby enhancing the sealing effect between the first matching portion 14 and the first connecting portion 13. Of course, as shown in Figure 6, there can also be multiple limiting portions 18, and the limiting portions 18 divide the connecting portion 111 into multiple sections, including a second section 138 assembled at the first matching portion 14 of the second cooling plate 12 and a first section 137 assembled at the first matching portion 14 of the first cooling plate 11. Along the extension direction of the first connecting portion 13, the second section 138 and the first section 137 have the same length.

[0073] Example 4

[0074] As shown in Figures 3 and 11, the fourth embodiment is based on the previous embodiment and specifically discloses that the cooling plate assembly includes a first sealing portion 15, the first matching portion 14 includes a matching portion 112, the first sealing portion 15 is located between the connecting portion 111 and the matching portion 112 and is pressed between the two, and the connection between the first connecting portion 13 and the first matching portion 14 is sealed to prevent fluid leakage, and a sealed connection between the first connecting portion 13 and the first matching portion 14 is achieved through the first sealing portion 15.

[0075] Example 5

[0076] Please refer to the fifth embodiment shown in Figure 12. This embodiment is based on the previous embodiment and specifically discloses that the mating portion 112 includes a large diameter section 1311 and a small diameter section 1312. The large diameter section 1311 abuts against the first sealing portion 15. Along the assembly direction of the first mating portion 14 and the first connecting portion 13, the small diameter section 1312 is closer to the limiting portion 18 than the large diameter section 1311. During assembly, along the radial direction of the first mating portion 14, the small diameter section 1312 is farther away from the first connecting portion 13 than the large diameter section 1311, thereby reducing the friction between the first sealing portion 15 and the first mating portion 14 during the assembly process, thereby reducing the probability of deformation and damage caused by friction.

[0077] In this embodiment, along the assembly direction of the first matching portion 14 and the first connecting portion 13, the small diameter section 1312 is closer to the limiting portion 18 than the large diameter section 1311. Of course, the large diameter section 1311 may be closer to the limiting portion 18 than the small diameter section 1312 as shown in Figure 13; or, as shown in Figure 14, along the assembly direction of the first matching portion 14 and the first connecting portion 13, small diameter sections 1312 are provided on both sides of the large diameter section 1311, or as shown in Figure 15, along the assembly direction of the first matching portion 14 and the first connecting portion 13, large diameter sections 1311 are provided on both sides of the small diameter section 1312, thereby reducing the friction between the first sealing portion 15 and the first matching portion 14 during the assembly process. In the scheme where large diameter sections 1311 are provided on both sides of the small diameter section 1312, the two large diameter sections 1311 play the role of multi-segment sealing, thereby improving the sealing effect.

[0078] Example 6

[0079] Referring to the sixth embodiment shown in Figure 16, this embodiment is based on the above embodiments and specifically discloses that the first connecting portion 13 is formed by a two-color injection molding process. The first connecting portion 13 is a polylauryl lactam material, and the first sealing portion 15 is a thermoplastic elastomer material or a liquid silicone material. After being formed by the two-color injection molding process, the first connecting portion 13 and the first sealing portion 15 are fixedly connected by injection molding. After assembly, the first sealing portion 15 is located at the periphery of the first matching portion 14, and the first connecting portion 13 is located at the periphery of the first sealing portion 15. Since the first sealing portion 15 is a thermoplastic elastomer material or a liquid silicone material, the thermoplastic elastomer material or the liquid silicone material is used. The compression deformation of the material realizes the sealing between the first connecting part 13 and the first matching part 14. Since the first connecting part 13 is made of polylaurolactam material, it provides supporting stiffness, thereby reducing the stretching of the first sealing part 15 and enhancing the compression of the first sealing part 15, thereby enhancing the sealing performance. Moreover, since the first sealing part 15 is located at the periphery of the first matching part 14, after the two first matching parts 14 are assembled with the first connecting part 13, when a position difference occurs in a direction perpendicular to the assembly direction of the first matching parts 14 and the first connecting part 13, the first connecting part 13 tilts, and the first sealing part 15 maintains sealing with the first matching part 14, thereby improving working stability.

[0080] The limiting portion 18 has a plurality of connecting holes 1122. Along the extension direction of the first connecting portion 13, the connecting holes 1122 are connected to the connecting portions 111 on both sides of the limiting portion 18. The first sealing portions 15 located on both sides of the limiting portion 18 are connected through the connecting holes 1122. During injection molding, when the glue is injected from one side of the limiting portion 18 to form the first sealing portion 15 on that side, the first sealing portion 15 is also formed on the other side of the limiting portion 18 through the connecting holes 1122, thereby simplifying the injection molding process.

[0081] The first mating portion 14 is formed by machining or cold heading.

[0082] Example 7

[0083] Please refer to the seventh embodiment shown in Figure 17. This embodiment is based on the above embodiments and specifically discloses that the first connection part 13 includes a reinforcement part 114. Along the extension direction of the first connection part 13, the reinforcement part 114 is located at both ends of the first connection part 13, thereby increasing the strength of both ends of the first connection part 13 and reducing the probability of cracking at both ends of the first connection part 13 during assembly.

[0084] Example 8

[0085] Please refer to the eighth embodiment shown in Figure 17. This embodiment is based on the above embodiments and specifically discloses that the contact pressure between the first sealing portion 15 and the matching portion 112 is a first pressure, the internal working pressure of the first connecting portion 13 is a second pressure, and along the assembly direction of the first matching portion 14 and the first connecting portion 13, the width of the area where the first pressure is greater than the second pressure is not less than 1mm, and along the circumference of the first connecting portion 13, the difference between the minimum and maximum values ​​of the first pressure does not exceed 10%. It should be noted that the 10% mentioned here means that the minimum value of the first pressure is not less than 90% of the maximum value of the first pressure. The maximum pressure value is not higher than 110% of the minimum pressure value of the first pressure, thereby improving the sealing performance of the first connecting part 13 and the first matching part 14 after assembly. Along the assembly direction perpendicular to the first matching part 14 and the first connecting part 13, the position difference between the first matching part 14 of the second cooling plate 12 and the first matching part 14 of the first cooling plate 11 does not exceed 3 mm, that is, the position difference of the first matching parts 14 installed on both sides of the first connecting part 13 along the assembly direction perpendicular to the first matching part 14 and the first connecting part 13 does not exceed 3 mm, thereby reducing the probability of leakage between the first connecting part 13 and the first matching part 14.

[0086] Example 9

[0087] Please refer to the ninth embodiment shown in Figures 25 to 55. This embodiment further discloses that the cooling plate assembly includes a first cooling plate 11, a second cooling plate 12 and a first connecting portion 13. The first cooling plate 11 and the second cooling plate 12 both include a first matching portion 14. One first connecting portion 13 is assembled with two first matching portions 14. The first connecting portion 13 has a first flow portion 131. The first matching portion 14 has a second flow portion 141. The first flow portion 131 is connected to the second flow portion 141. The medium in the first cooling plate 11 flows to the first cooling plate 11. The second circulation part 141 connected to the plate 11, since the first connecting part 13 is assembled with the two first matching parts 14, the medium in the first matching part 14 connected to the first cooling plate 11 flows into the first connecting part 13, and then flows into the first matching part 14 connected to the second cooling plate 12, and then flows into the second cooling plate 12. In other embodiments, as shown in Figure 55, the cooling plate assembly includes a second cooling plate 12 and a first connecting part 13, the second cooling plate 12 includes a first matching part 14, and the first connecting part 13 is assembled with the first matching part 14.

[0088] As shown in Figures 25 to 55, the cooling plate assembly includes at least one first connecting portion 13, at least one first matching portion 14 and at least one first sealing portion 15. The first circulation portion 131 is communicated with the second circulation portion 141 and is sealed by the first sealing portion 15. Along the radial direction of the first connecting portion 13, for the inner circumference and outer circumference of the first connecting portion 13, the circumference of the first connecting portion 13 that is relatively close to the first matching portion 14 is defined as the first circumference 132. Along the radial direction of the first connecting portion 13, for the inner circumference and outer circumference of the first matching portion 14, the circumference of the first matching portion 14 that is relatively close to the first connecting portion 13 is defined as the second circumference 142. The first circumference 132 is sealedly connected to the first sealing portion 15, and the second circumference 142 is sealedly connected to the first sealing portion 15, thereby The first circulation portion 131 and the second circulation portion 141 are sealed, and the fluid does not flow outside the cooling plate assembly. The cooling plate assembly includes a first rib 16, which is connected to the first connecting portion 13. The first rib 16 abuts against the first sealing portion 15. Therefore, in the axial direction of the first connecting portion 13, the first rib 16 limits the maximum deformation of the first sealing portion 15, reduces the probability of sealing failure caused by excessive deformation of the first sealing portion 15, and thus improves the sealing reliability of the first sealing portion 15. In this embodiment, the first rib 16 and the first connecting portion 13 are an integrated structure, which limits the maximum deformation of the first rib 16, thereby reducing the probability of sealing failure caused by excessive deformation of the first sealing portion 15, and thus improves the sealing reliability of the first sealing portion 15. Of course, the first rib 16 can also be an integral structure with the first matching portion 14, or the first rib 16 can be an integral structure with one of the first connecting portion 13 and the first matching portion 14 and be sealed with the other. In other embodiments, there can also be a gap between the first rib 16 and the first sealing portion 15 along the axial direction of the first connecting portion 13. It should be noted that in this embodiment, due to the small deformation of the first sealing portion 15, the first sealing portion 15 and the first rib 16 are not in contact. However, since there is a gap between the first rib 16 and the first sealing portion 15 in the axial direction of the first connecting portion 13, that is, in the axial direction of the first connecting portion 13, 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 thereby improve the sealing reliability of the first sealing portion 15.

[0089] A manufacturing method for a cooling plate assembly is also provided to produce a first connecting portion 13 and a first matching portion 14; wherein the above steps include forming a first sealing portion 15 and a first rib 16 on at least one of the first connecting portion 13 and the first matching portion 14, that is, the first sealing portion 15 and the first rib 16 can be formed on the first connecting portion 13, or the first sealing portion 15 and the first rib 16 can be formed on the first matching portion 14, the first sealing portion 15 is closer to the central axis of the first connecting portion 13 than the first rib 16, the first sealing portion 15 and the first rib 16 are arranged at an axial distance from the first connecting portion 13, and the first connecting portion 13 and the first matching portion 14 are assembled.

[0090] When the first connecting portion 13 and the first matching portion 14 are assembled, the friction between the first rib 16 and the first connecting portion 13 or the first matching portion 14 is reduced because the first sealing portion 15 is closer to the central axis of the first connecting portion 13 than the first rib 16 .

[0091] Furthermore, the compression rate of the first sealing portion 15 is between 15% and 55%. Since too large a compression rate may cause excessive deformation of the first sealing portion 15, thereby causing a decrease in sealing reliability, the compression rate of the first sealing portion 15 is controlled between 15% and 55% to reduce the possibility of a possible decrease in sealing reliability.

[0092] Example 10

[0093] Please refer to the tenth embodiment shown in Figures 25, 27, 28, and 32-34. This embodiment is based on the ninth embodiment and specifically discloses that the first sealing portion 15 is connected to the first connecting portion 13, and the first rib 16 is connected to the first connecting portion 13. It should be noted that in this embodiment, the first sealing portion 15 and the first connecting portion 13 are an integrated structure, and the first rib 16 and the first connecting portion 13 are an integrated structure, which satisfies the first sealing portion 15 and the first connecting portion 13, and the first rib 16 is connected to the first connecting portion 13. In other embodiments, as shown in Figures 27 and 28, the first sealing portion 15 and the first rib 16 may be an integrated structure, and the first sealing portion 15 and the first rib 16 may be an integrated structure with the first connecting portion 13. The connecting portion 13 is a split structure, or the first sealing portion 15, the first rib 16, and the first connecting portion 13 are all split structures, satisfying the first sealing portion 15 and the first circumferential surface 132 of the first connecting portion 13 are sealed, the first sealing portion 15 and the second circumferential surface 142 of the first matching portion 14 are sealed, along the axial direction of the first connecting portion 13, the first connecting portion 13 has a first end portion 133, the first sealing portion 15 is closer to the first end portion 133 than the first rib 16, along the radial direction of the first connecting portion 13, the first connecting portion 13 is located at the outer periphery of the first matching portion 14, 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 When the connecting portion 13 is assembled with the first matching portion 14, the first sealing portion 15 is displaced and deformed under the action of the friction force between the first sealing portion 15 and the first matching portion 14. Therefore, the structure of the first rib 16 protruding relative to the first circumferential surface 132 can limit the maximum deformation of the first sealing portion 15 by the first rib 16 in the axial direction of the first connecting portion 13, thereby 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. The first section 137 is assembled with the first matching portion 14 of the first cooling plate 11, and the second section 138 is assembled with the first matching portion 11 of the second cooling plate 12. 4 assembly, the first connecting portion 13 includes two first end portions 133, the two first end portions 133 are respectively located at the first section 137 and the second section 138, the first sealing portion 15 includes a first sub-sealing portion 151 and a second sub-sealing portion 152, the first rib 16 includes a first sub-rib 161 and a second sub-rib 162, the second sub-sealing portion 152 and the first section 137 are an integral structure, the second sub-rib 162 and the first section 137 are an integral structure, the first sub-sealing portion 151 and the second section 138 are an integral structure, and the first sub-rib 161 and the second section 138 are an integral structure. Along 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 161.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, 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, 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 the two first matching portions 14, and 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 16, or the first rib 16 is closer to the first end portion 133 relative to the first sealing portion 15. The first sealing portion 15 and the first rib 16 here refer to the first sub-sealing portion 151 and the first sub-rib 161, the second sub-sealing portion 152 and the second sub-rib 162, that is, when the first sealing portion 15 represents the first sub-sealing portion 151, the first rib 16 represents the first sub-rib 161, and when the first sealing portion 15 represents the second sub-sealing portion 152, the first rib 16 represents the second sub-rib 162. Since the first sealing portion 15 protrudes relative to the first circumferential surface 132, the first rib 16 A sealing portion 15 is connected to the second circumferential surface 142, and the first sealing portion 15 is sealed with the second circumferential surface 142. Therefore, the resistance during assembly of the first connecting portion 13 and the first matching portion 14 includes the friction between the first sealing portion 15 and the second circumferential surface 142. Compared with the solution in which the first circumferential surface 132 contacts the second circumferential surface 142 and the first circumferential surface 132 and the second circumferential surface 142 are sealed, since the contact area between the first sealing portion 15 and the second circumferential surface 142 is smaller than the contact area between the first circumferential surface 132 and the second circumferential surface 142, the first sealing portion 15 replaces the first circumferential surface 132 and the second circumferential surface 142 to seal, thereby reducing the contact area with the second circumferential surface 142, thereby reducing the resistance encountered during assembly of the first connecting portion 13 and the first matching portion 14, and reducing the risk of deformation during assembly of the first connecting portion 13 and the first matching portion 14.

[0094] Regarding the manufacturing method of the cooling plate assembly, before the first connecting portion 13 and the first matching portion 14 are assembled, along the radial direction of the first connecting portion 13, the protruding distance of the first sealing portion 15 relative to the first circumferential surface 132 is a first distance D1, and the protruding distance of the first rib 16 relative to the first circumferential surface 132 is a second distance D2, and the first distance D1 is greater than the second distance D2. Since the protruding distance of the first rib 16 is lower than the protruding distance of the first sealing portion 15, the friction between the first rib 16 and the second circumferential surface 142 is reduced, thereby reducing the resistance encountered by the first connecting portion 13 and the first matching portion 14 during the assembly process of the first connecting portion 13 and the first matching portion 14. In addition, because the first rib 16 is protruding, the first rib 16 plays a guiding role for the first matching portion 14, thereby reducing the probability of the first circumferential surface 132 being torn due to excessive local interference caused by position deviation when the first matching portion 14 and the first connecting portion 13 are assembled.

[0095] Example 11

[0096] Please refer to the eleventh embodiment shown in Figures 25 to 31. The difference between this embodiment and the tenth embodiment is that, along the axial direction of the first connecting portion 13, the first rib 16 is closer to the first end portion 133 relative to the first sealing portion 15, and the first sealing portion 15 and the first rib 16 protrude relative to the first circumferential surface 132. Since the first sealing portion 15 protrudes relative to the first circumferential surface 132, the first connecting portion 13 is assembled with the first matching portion 14. Due to the friction between the first sealing portion 15 and the first matching portion 14, the first sealing portion 15 is displaced and deformed. 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 limits the maximum deformation of the first sealing portion 15, reduces the probability of sealing failure caused by excessive deformation of the first sealing portion 15, and thereby improves 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 161 is relative to The first sub-sealing portion 151 is closer to the second cooling plate 12, 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, thereby improving the sealing reliability of the first sub-sealing portion 151 and the second sub-rib portion 162.

[0097] Regarding the manufacturing method of the cooling plate assembly, before the first connecting portion 13 and the first matching portion 14 are assembled, along the radial direction of the first connecting portion 13, the protruding distance of the first sealing portion 15 relative to the first circumferential surface 132 is a first distance D1, and the protruding distance of the first rib 16 relative to the first circumferential surface 132 is a second distance D2, and the first distance D1 is not less than the second distance D2. Since the protruding distance of the first sealing portion 15 is not less than the protruding 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 of the first connecting portion 13 and the first matching portion 14 during the assembly process of the first connecting portion 13 and the first matching portion 14. Because the first connecting portion 13 and the first matching portion 14 are assembled, the first sealing portion 15 is protruding along the first end portion 13 3 points to the displacement deformation in the direction of the center line 134, so the first sealing part 15 is less able 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 circulation part 131 and the second circulation 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 matching part 14, that is, the first sealing part 15, is negative pressure. The direction of the negative pressure is along the first end part 133 pointing to the direction of 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 providing the sealing reliability of the first sealing part 15.

[0098] Example 12

[0099] Please refer to the twelfth embodiment shown in Figures 35 to 40. This embodiment is based on the ninth embodiment and specifically discloses that the cooling plate assembly includes a second rib 17, and the second rib 17 is connected to the first connecting portion 13. It should be noted that in this embodiment, the second rib 17 and the first connecting portion 13 are an integrated structure, which satisfies the 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 integrated structure, while the second rib 17, the first rib 16, and the first sealing portion 15 may be an integrated structure with the first connecting portion 13 as a split structure. The second rib 17 protrudes relative to the first circumferential surface 132 and extends along the first circumferential surface 132. In the axial direction of the first connecting portion 13, the second rib 17 is located on one side of the first sealing portion 15, and the first rib 16 is located on the other side of the first sealing portion 15. Since the second rib 17 protrudes relative to the first circumferential surface 132, and the first sealing portion 15 is closer to the first end portion 133 relative to the first rib 16, the second rib 17 is located on the other side of the first sealing portion 15. Therefore, the second rib 17 is closer to the first end portion 133 relative to the first sealing portion 15. The second rib 17 guides the first matching portion 14, reducing the probability of tearing of the first circumferential surface 132 due to excessive local interference caused by position deviation when the first matching portion 14 and the first connecting portion 13 are assembled.

[0100] Regarding the manufacturing method of the cooling plate assembly, before the first connecting portion 13 and the first matching portion 14 are assembled, along the radial direction of the first connecting portion 13, the protruding distance of the second rib 17 relative to the first circumferential surface 132 is a third distance D3, and the third distance D3 is smaller than the first distance D1. Since the protruding distance of the second rib 17 is smaller than the first sealing portion 15, the friction between the second rib 17 and the second circumferential surface 142 is reduced, thereby reducing the resistance encountered by the first connecting portion 13 and the first matching portion 14 during the assembly process.

[0101] 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 portion 15, and the second rib 17 is connected to the second circumferential surface 142, the second rib 17 has a shielding effect on the first sealing portion 15, reducing the probability of impurities invading the first sealing portion 15, thereby improving the sealing reliability of the first sealing portion 15.

[0102] Regarding the manufacturing method of the cooling plate assembly, before the first connecting portion 13 is assembled with the first matching portion 14, along the axial direction of the first connecting portion 13, the end of the second rib 17 close to the first end portion 133 is defined as the first sub-portion 171, and the second rib 17 includes a second sub-portion 172. Before the first connecting portion 13 is assembled with the first matching portion 14, along the radial direction of the first connecting portion 13, the protruding distance of the first sub-portion 171 relative to the first circumferential surface 132 is the fourth distance D4, and the protruding distance of the second sub-portion 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 protruding distance of the part close to the first end portion 133 relative to the first circumferential surface 132 is small, thereby improving the guiding effect of the second rib 17 on the first matching portion 14.

[0103] Example 13

[0104] Please refer to the thirteenth embodiment shown in Figures 25, 27, 28, and 41-44. The difference between this embodiment and the ninth embodiment is that the first sealing portion 15 is connected to the first matching portion 14, and the first rib 16 is connected to the first matching portion 14. It should be noted that in this embodiment, the first sealing portion 15 and the first matching portion 14 are an integrated structure, and the first rib 16 and the first matching portion 14 are an integrated structure, which satisfies the first sealing portion 15 and the first matching portion 14, and the first rib 16 is connected to the first matching portion 14. In other embodiments, the first sealing portion 15 and the first rib 16 may be an integrated structure, and the first sealing portion 15 and the first rib 16 may be an integrated structure with the first matching portion 14. The coupling portion 14 is a split structure, which satisfies the sealing between the first sealing portion 15 and the first circumferential surface 132 of the first connecting portion 13, and the sealing between the first sealing portion 15 and the second circumferential surface 142 of the first matching portion 14. Along the axial direction of the first connecting portion 13 and the axial direction of the first matching portion 14, the second end portion 143 is defined as the end of the first matching portion 14 that is relatively close to the first connecting portion 13. Along the axial direction of the first matching portion 14, the first rib 16 is closer to the second end portion 143 relative to the first sealing portion 15. Along the radial direction of the first matching portion 14, the first matching portion 14 is located on the inner circumference of the first connecting portion 13. Along the radial direction of the first matching portion 14, the first sealing portion 15 and the first rib 16 protrude relative to the second circumferential surface 142. The first sealing portion 15 protrudes relative to the second circumferential surface 142, the first connecting portion 13 is assembled with the first matching portion 14, and the first sealing portion 15 is displaced and deformed under the action of the friction between the first sealing portion 15 and the first connecting portion 13. 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 then the first sealing portion 15 is sealed with the first circumferential surface 132, so The resistance during assembly of the first connecting portion 13 and the first matching portion 14 includes the friction force between the first sealing portion 15 and the first circumferential surface 132. Compared with the scheme in which the first circumferential surface 132 contacts the second circumferential surface 142 and the first circumferential surface 132 and the second circumferential surface 142 are sealed, since the contact area between the first sealing portion 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 first sealing portion 15 replaces the second circumferential surface 142 to seal the first circumferential surface 132, thereby reducing the contact area with the first circumferential surface 132, thereby reducing the resistance encountered during assembly of the first connecting portion 13 and the first matching portion 14, and reducing the risk of deformation during assembly of the first connecting portion 13 and the first matching portion 14.

[0105] Regarding the manufacturing method of the cooling plate assembly, before the first connecting portion 13 and the first matching portion 14 are assembled, along the radial direction of the first matching portion 14, the protruding distance of the first sealing portion 15 relative to the second circumferential surface 142 is the sixth distance D6, and the protruding distance of the first rib 16 relative to the second circumferential surface 142 is the seventh distance D7, and the sixth distance D6 is greater than the seventh distance D7. Since the protruding distance of the first rib 16 is lower than the protruding distance of the first sealing portion 15, the friction between the first rib 16 and the first circumferential surface 132 is reduced, thereby reducing the resistance encountered by the first connecting portion 13 and the first matching portion 14 during the assembly process. In addition, because the first rib 16 is protruding, the first rib 16 plays a guiding role for the first matching portion 14, reducing the probability of the second circumferential surface 142 being torn due to excessive local interference caused by position deviation when the first matching portion 14 and the first connecting portion 13 are assembled.

[0106] Example 14

[0107] Please refer to the fourteenth embodiment shown in Figures 25, 27, 28, 41, 42, 45, and 46. The difference between this embodiment and the thirteenth embodiment is that along the axial direction of the first matching portion 14, the first sealing portion 15 is closer to the second end portion 143 relative to the first rib portion 16, and along the radial direction of the first matching portion 14, the first sealing portion 15 and the first rib portion 16 protrude relative to the second circumferential surface 142. Since the first sealing portion 15 protrudes relative to the second circumferential surface 142, the first connecting portion 13 is assembled with the first matching portion 14, and the friction between the first sealing portion 15 and the first connecting portion 13 is reduced. Under the action of friction, the first sealing portion 15 is displaced and deformed, so 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. Before the first connecting portion 13 is assembled with the first matching portion 14, along the radial direction of the first matching portion 14, the protrusion distance of the first sealing portion 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 D6. The sixth distance D6 is not less than the seventh distance D7. Since the protruding distance of the first sealing portion 15 is not less than the protruding 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 of the first connecting portion 13 and the first matching portion 14 during the assembly process of the first connecting portion 13 and the first matching portion 14. Because the first connecting portion 13 and the first matching portion 14 are assembled, the first sealing portion 15 is deformed in the axial direction of the first matching portion 14, and therefore the first sealing portion 15 is less able to withstand negative pressure. It should be noted that the negative pressure here refers to The fact is that when the fluid flows in the first circulation portion 131 and the second circulation portion 141, there is a situation where the pressure of the fluid is lower than the external atmospheric pressure. At this time, at the sealing portion of the first connecting portion 13 and the first matching portion 14, that is, the first sealing portion 15, there is a pressure generated by the external atmospheric pressure on the first sealing portion 15, which is a negative pressure. Since the first rib 16 can limit the maximum deformation of the first sealing portion 15, the probability of sealing failure caused by excessive deformation of the first sealing portion 15 is reduced, thereby improving the first sealing portion 15's ability to withstand negative pressure, thereby providing the first sealing portion 15 with sealing reliability.

[0108] Example 15

[0109] Please refer to the fifteenth embodiment shown in Figures 47 to 49. This embodiment is based on the previous embodiment and specifically discloses that the cooling plate assembly includes a second rib 17, and the second rib 17 is connected to the first matching portion 14. It should be noted that in this embodiment, the second rib 17 and the first matching portion 14 are an integrated structure, which satisfies the connection between the second rib 17 and the first matching portion 14. In other embodiments, the second rib 17, the first rib 16, and the first sealing portion 15 may be an integrated structure, while the integrated structure of the second rib 17, the first rib 16 and the first sealing portion 15 is a split structure with the first matching portion 14. The second rib 17 protrudes relative to the second circumferential surface 142. Along the axial direction of the first matching portion 14, the second rib 17 is located on one side of the first sealing portion 15, and the first rib 16 is located on the other side of the first sealing portion 15. Since the second rib 17 protrudes relative to the second circumferential surface 142 and the first sealing portion 15 is relatively The first rib 16 is closer to the second end 143, and the second rib 17 is located on the other side of the first sealing portion 15. Therefore, the second rib 17 is closer to the second end 143 relative to the first sealing portion 15. The second rib 17 guides the first matching portion 14, reducing the probability of tearing of the second circumferential surface 142 due to excessive local interference caused by position deviation when the first matching portion 14 is assembled with the first connecting portion 13. Before the first connecting portion 13 is assembled with the first matching portion 14, the protruding distance of the second rib 17 relative to the second circumferential surface 142 along the radial direction of the first matching portion 14 is the eighth distance D8, and the eighth distance D8 is less than the sixth distance D6. Since the protruding distance of the second rib 17 is less than the first sealing portion 15, the friction between the second rib 17 and the second circumferential surface 142 is reduced, thereby reducing the resistance encountered by the first connecting portion 13 and the first matching portion 14 during the assembly process of the first connecting portion 13 and the first matching portion 14.

[0110] 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 portion 15, and the second rib 17 is connected to the first circumferential surface 132, the second rib 17 has a shielding effect on the first sealing portion 15, reducing the probability of impurities invading the first sealing portion 15, thereby improving the sealing reliability of the first sealing portion 15.

[0111] Example 16

[0112] Please refer to the sixteenth embodiment shown in Figures 40 and 41. The difference between this embodiment and the above embodiments is that along the radial direction of the first connection portion 13, the first connection portion 13 is located at the inner periphery of the first matching portion 14. Of course, it is also possible that along the radial direction of the first connection portion 13, the first connection portion 13 is located at the outer periphery of one first matching portion 14, and the first connection portion 13 is located at the inner periphery of another first matching portion 14.

[0113] Example 17

[0114] Please refer to the seventeenth embodiment shown in Figure 42. Based on the above embodiments, this embodiment specifically discloses a cooling plate assembly including a limiting portion 18. Along the radial direction of the first connecting portion 13, the limiting portion 18 is connected to the first connecting portion 13. Along the axial direction of the first matching portion 14, the first connecting portion 13 has a second end 143. Along the axial direction of the first matching portion 14, the second end 143 is defined as an end of the first matching portion 14 that is relatively close to the first connecting portion 13. Along a plane perpendicular to the axial direction of the first connecting portion 13, the orthographic projection of the limiting portion 18 on the plane is parallel to the orthographic projection of the second end 143 on the plane. The orthographic projection of the limiting portion 18 at least partially overlaps with the orthographic projection of the second end portion 143 at least partially overlaps. Therefore, when the first connecting portion 13 is assembled with the first matching portion 14, along the assembly direction of the first connecting portion 13 and the first matching portion 14, the limiting portion 18 has a blocking effect on the first matching portion 14, limiting the relative movement of the first connecting portion 13 and the first matching portion 14. The limiting portion 18 has a blocking effect during assembly, limiting the maximum length of the assembly part of the first connecting portion 13 and the first matching portion 14, and then playing a positioning role, reducing the difficulty of installation.

[0115] Embodiment 18

[0116] Please refer to the eighteenth embodiment shown in Figures 53 to 55. This embodiment is based on the above embodiments and specifically discloses that the first connecting portion 13 is formed by a two-color injection molding process. The first connecting portion 13 includes a first layer portion 135 and a second layer portion 136. The first layer portion 135 is a plastic material and the second layer portion 136 is an elastic material. In this embodiment, the first layer portion 135 is PA12 rigid plastic and the second layer portion 136 is a thermoplastic elastomer material or a liquid silicone material. The first layer portion 135 and the second layer portion 136 are fixedly connected. After being formed by the two-color injection molding process, the first layer portion 135 and the second layer portion 136 are fixedly connected by injection molding. After the first connecting portion 13 is assembled with the first matching portion 14, due to the second layer portion 135 36 is a thermoplastic elastomer material or a liquid silicone material, and the sealing between the first connecting part 13 and the first matching part 14 is achieved by the compression deformation of the thermoplastic elastomer material or the liquid silicone material. Since the first layer 135 is a PA12 rigid plastic, it provides support stiffness to reduce the stretching of the first sealing rib, enhances the compression effect of the first sealing rib, and thus enhances the sealing performance. Moreover, since the first layer 135 is located on the outer periphery of the second layer 136, after the two first matching parts 14 are assembled with the first connecting part 13, when a position deviation occurs along the assembly direction of the first connecting part 13 and the first matching part 14, the first connecting part tilts, and the first sealing rib and the first matching part 14 remain sealed, thereby improving the sealing reliability.

[0117] Example 19

[0118] Referring to the nineteenth embodiment illustrated in Figures 25 to 55 , this embodiment, based on the above embodiments, specifically discloses that the contact pressure between the first sealing portion 15 and the first mating portion 14 or the first connecting portion 13 is a first pressure, and the internal working pressure of the first connecting portion 13 is a second pressure. Along the axial direction of the first connecting portion 13, the width of the region where the first pressure is greater than the second pressure is not less than 0.6 mm. Along a direction perpendicular to the axial direction of the first connecting portion 13, the positional difference between the axis of the first connecting portion 13 and the axis of the first mating portion 14 does not exceed 3 mm. After the first connecting portion 13 and the first mating portion 14 are assembled, the compression rate of the first sealing portion 15 is between 15% and 55%, reducing the probability of seal failure between the first connecting portion 13 and the first mating portion 14, thereby improving sealing reliability. The Shore A hardness of the second layer 136 is between 40 and 65. Due to the protruding configuration of the first sealing portion 15 and the first rib 16, demolding presents a certain degree of difficulty. Controlling the Shore A hardness of the second layer 136 between 40 and 65 helps reduce the demolding difficulty. It should be noted that the above provides a detailed introduction to the cooling plate assembly provided in this application.
