[0039] Embodiment 3

[0040] like Figure 3 The second embodiment shown in the figure is based on the scheme in which the connecting member 11 is located at the periphery of the mounting portion 13 and the positioning portion 112 is fixedly connected to the connecting member 11 in the previous embodiment. Specifically, the number of the positioning portion 112 is one, the connecting member 11 includes a connecting portion 111, and the connecting portion 111 includes a first connecting portion 1120 and a second connecting portion 1130. Along the extension direction of the connecting member 11, the first connecting portion 1120 and the second connecting portion 1130 are respectively located on both sides of the positioning portion 112, and the first connecting portion 1120 is sealed with the mounting portion 13 of the first cooling plate 12. The second connecting portion 1130 is sealed and connected with the mounting portion 13 of the second cooling plate 14. Along the extension direction of the connecting member 11, the first connecting portion 1120 and the second connecting portion 1130 have the same length. Along the extension direction of the connecting member 11, the mounting portion 13 of the first cooling plate 12 and the mounting portion 13 of the first cooling plate 12 have the same assembly length as the connecting portion 111, thereby reducing the probability of one mounting portion 13 having a longer assembly length and causing another mounting portion 13 to have a shorter assembly length, thereby enhancing the sealing effect of the mounting portion 13 and the connecting member 11. Of course, it can also be as Figure 6 As shown, there are multiple positioning portions 112, which divide the connecting portion 111 into multiple sections, including a first connecting portion 1120 assembled with the mounting portion 13 away from the first cooling plate 12 and a second connecting portion 1130 assembled with the mounting portion 13 away from the second cooling plate 14. Along the extension direction of the connecting member 11, the first connecting portion 1120 and the second connecting portion 1130 have the same length.

[0041] Embodiment 4

[0042] like Figure 3 and Fig.11The fourth embodiment shown is based on the previous embodiment and specifically discloses that the cooling plate assembly includes a sealing portion 113, and the mounting portion 13 includes a matching portion 131. The sealing portion 113 is located between the connecting portion 111 and the matching portion 131 and is pressed between the two, so as to seal the connection between the connecting member 11 and the mounting portion 13 to prevent fluid leakage, and a sealed connection between the connecting member 11 and the mounting portion 13 is achieved through the sealing portion 113.

[0043] Embodiment 5

[0044] Please refer to Fig.12 The fifth embodiment shown is based on the previous embodiment and specifically discloses that the mating portion 131 includes a large diameter section 1311 and a small diameter section 1312. The large diameter section 1311 abuts against the sealing portion 113. Along the assembly direction of the mounting portion 13 and the connecting member 11, the small diameter section 1312 is closer to the positioning portion 112 than the large diameter section 1311. During assembly, along the radial direction of the mounting portion 13, the small diameter section 1312 is farther away from the connecting member 11 than the large diameter section 1311, thereby reducing the friction between the sealing portion 113 and the mounting portion 13 during assembly, thereby reducing the probability of deformation and damage caused by friction.

[0045] In this embodiment, along the assembly direction of the mounting portion 13 and the connecting member 11, the small diameter section 1312 is closer to the positioning portion 112 than the large diameter section 1311. Of course, it can also be as follows Fig.13 The large diameter section 1311 shown is closer to the positioning portion 112 than the small diameter section 1312; or Fig.14 As shown in the figure, along the assembly direction of the mounting portion 13 and the connecting member 11, both sides of the large diameter section 1311 are provided with small diameter sections 1312, or as shown in the figure, Fig.15 As shown, along the assembly direction of the mounting portion 13 and the connecting member 11, large diameter sections 1311 are provided on both sides of the small diameter section 1312 to reduce the friction between the sealing portion 113 and the mounting portion 13 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-stage sealing, thereby improving the sealing effect.

[0046] Embodiment 6

[0047] Please refer to Figure 7-10 The sixth embodiment shown in the figure is based on the fourth and fifth embodiments, and specifically discloses that the positioning portions 112 are arranged continuously or at intervals along the circumference of the connecting member 11. Figure 12-Figure 15As shown, the mounting portion 13 includes an end portion 133, and the end portion 133 is closer to the positioning portion 112 than the matching portion 131. The end of the end portion 133 close to the positioning portion 112 has a chamfer 1331. The chamfer 1331 facilitates the alignment of the connecting member 11 and the mounting portion 13 during assembly, and is beneficial for the mounting portion 13 to enter the connecting member 11. The chamfer 1331 abuts against the positioning portion 112, which facilitates the assembly and positioning of the mounting portion 13 and the connecting member 11, and enhances the force uniformity of the sealing portion 113 and the mounting portion 13 along the circumference of the mounting portion 13.

[0048] Embodiment 7

[0049] Reference Fig.16 The seventh embodiment shown in the figure is based on the above embodiments and specifically discloses that the connector 11 is formed by a two-color injection molding process. The connector 11 is made of polylaurolactam material, and the sealing portion 113 is made of a thermoplastic elastomer material or a liquid silicone material. After being formed by the two-color injection molding process, the connector 11 and the sealing portion 113 are fixedly connected by injection molding. After assembly, the sealing portion 113 is located at the periphery of the mounting portion 13, and the connector 11 is located at the periphery of the sealing portion 113. Since the sealing portion 113 is made of a thermoplastic elastomer material or a liquid silicone material, the thermoplastic elastomer material or the liquid silicone material is used to fix the connector 11 and the sealing portion 113. The compression deformation of the rubber material realizes the seal between the connecting piece 11 and the mounting portion 13. Since the connecting piece 11 is made of polylaurolactam material, it provides supporting stiffness, thereby reducing the stretching of the sealing portion 113 and enhancing the compression of the sealing portion 113, thereby enhancing the sealing performance. Moreover, since the sealing portion 113 is located at the periphery of the mounting portion 13, after the two mounting portions 13 are assembled with the connecting piece 11, when a position difference occurs in a direction perpendicular to the assembly direction of the mounting portion 13 and the connecting piece 11, the connecting piece 11 tilts, and the sealing portion 113 and the mounting portion 13 maintain sealing, thereby improving working stability.

[0050] The positioning portion 112 has a plurality of connecting holes 1122. Along the extension direction of the connecting member 11, the connecting holes 1122 are connected to the connecting portions 111 on both sides of the positioning portion 112. The sealing portions 113 on both sides of the positioning portion 112 are connected through the connecting holes 1122. During injection molding, when the sealant 113 on one side of the positioning portion 112 is formed, the sealing portion 113 on the other side of the positioning portion 112 is also formed through the connecting holes 1122, thereby simplifying the injection molding process.

[0051] The mounting portion 13 is formed by machining or cold heading.

[0052] Embodiment 8

[0053] Please refer to Fig.17The eighth embodiment shown is based on the above embodiments and specifically discloses that the connector 11 includes a reinforcing portion 114. The reinforcing portion 114 is located at both ends of the connector 11 along the extension direction of the connector 11, thereby increasing the strength of both ends of the connector 11 and reducing the probability of cracking at both ends of the connector 11 during assembly.

[0054] Embodiment 9

[0055] Please refer to Fig.17 The ninth embodiment shown is based on the above embodiments, and specifically discloses that the contact pressure between the sealing portion 113 and the matching portion 131 is the first pressure, the internal working pressure of the connector 11 is the second pressure, and along the assembly direction of the mounting portion 13 and the connector 11, the width of the area where the first pressure is greater than the second pressure is not less than 1 mm, and along the circumference of the connector 11, 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, and the maximum value of the first pressure is not higher than 110% of the minimum value of the first pressure, so as to improve the sealing performance of the connector 11 after the mounting portion 13 is assembled. Along the assembly direction perpendicular to the mounting portion 13 and the connector 11, the position difference between the mounting portion 13 of the first cooling plate 12 and the mounting portion 13 of the second cooling plate 14 does not exceed 3 mm, that is, the position difference of the mounting portions 13 installed on both sides of the connector 11 along the assembly direction perpendicular to the mounting portion 13 and the connector 11 does not exceed 3 mm, thereby reducing the probability of leakage between the connector 11 and the mounting portion 13.

[0056] It should be noted that: the above is a detailed introduction to the cooling plate assembly provided by the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the core idea of ​​the present application.
