Along the axial direction of the connecting piece, the second abutting portion is farther away from the first end portion than the first abutting portion, or the distance between the second abutting portion and the first end portion is the same as the distance between the first abutting portion and the first end portion. Therefore, when the installing clamp clamps the connecting piece, the installing clamp is limited by the first abutting portion and the second abutting portion, reducing the probability of misalignment of the connecting piece during installation, thereby improving the connection sealing effect of the connecting piece.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and technical solutions. It should be understood that the specific technical solutions described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] See also Figures 1-20The utility model provides a cooling plate assembly, including a first cold plate 11 and a connector 12, the connector 12 including a connecting section 121 and at least one connecting section 122, the connecting section 121 and the connecting section 122 are located along the axial direction of the connector 12, the first cold plate 11 includes a matching portion 111, the matching portion 111 is fixedly connected to the connecting section 122, the matching portion 111 has a first flow channel 1111, the connecting section 122 has a second flow channel 1221, after the matching portion 111 is fixedly connected to the connecting section 122, the first flow channel 1111 is connected to the second flow channel 1221, the first cold plate 11 is connected to the connector 12, and the fluid in the first cold plate 11 flows through the fixedly connected matching portion 111 and the connecting section 122 Inserted into the connector 12, along the radial direction of the connector 12, the connecting section 122 is located on the outer peripheral side of the matching portion 111, the connector 12 includes at least one first limiting portion 123, the first limiting portion 123 includes a first limiting surface 1231, along the axial direction of the connector 12, the end of the connecting section 122 away from the connecting section 121 is defined as the first end 1223, along the axial direction of the connector 12, the first limiting surface 1231 is located on a side surface of the first limiting portion 123 away from the first end 1223, because the matching portion 111 is fixedly connected to the connecting section 122, the first limiting surface 1231 is located on a side surface of the first limiting portion 123 away from the first end 1223, so the mounting fixture 13 is fixed to the connector 12 and the first cold When the plate 11 is installed, the mounting fixture 13 contacts the first limiting surface 1231, and the first limiting surface 1231 includes a first abutting portion 12311 and at least one second abutting portion 12312. Along the radial direction of the connecting member 12, the second abutting portion 12312 is farther from the axis of the connecting member 12 than the first abutting portion 12311. Since the second abutting portion 12312 is farther from the first end portion 1223 than the first abutting portion 12311, after the mounting fixture 13 contacts the first limiting surface 1231, the first abutting portion 12311 and the second abutting portion 12312 limit the mounting fixture 13, limiting the movement of the mounting fixture 13 in the radial direction of the connecting member 12 away from the connecting member 12, thereby reducing Since the mounting fixture 13 and the connecting member 12 slide, the probability of the connecting member 12 and the first cold plate 11 being misaligned is caused, thereby improving the connection sealing effect between the connecting member 12 and the first cold plate 11, and since the second abutting portion 12312 is farther away from the first end portion 1223 than the first abutting portion 12311 along the axial direction of the connecting member 12, when the mounting fixture 13 clamps the connecting member 12 and the first cold plate 11 for installation, the force of the first limiting surface 1231 on the mounting fixture 13 makes the mounting fixture 13 clamp the connecting member 12 tighter, further reducing the probability of the mounting fixture 13 and the connecting member 12 sliding, thereby improving the connection sealing effect between the connecting member 12 and the first cold plate 11.Of course, in other embodiments, the distance between the second abutting portion 12312 and the first end portion 1223 and the distance between the first abutting portion 12311 and the first end portion 1223 may be the same along the axial direction of the connecting member 12. Since the second abutting portion 12312 and the first abutting portion 12311 are at the same distance from the connecting section 122, when the mounting fixture 13 contacts the first abutting portion 12311 and the second abutting portion 12312, the mounting fixture 13 will not be subjected to a force in the radial direction away from the connecting member 12 of the connecting member 12. Therefore, the first abutting portion 12311 and the second abutting portion 12312 can also play a limiting role on the mounting fixture 13, restricting the mounting fixture 13 from moving in the radial direction away from the connecting member 12 of the connecting member 12, thereby reducing the probability of eccentricity between the connecting member 12 and the first cold plate 11, thereby improving the connection sealing effect between the connecting member 12 and the first cold plate 11. In this embodiment, along the radial direction of the connecting member 12, the first limiting portion 123 is fixedly connected to the connecting section 121, and along the radial direction of the connecting member 12, the first abutting portion 12311 is located at the connection between the first limiting surface 1231 and the connecting section 121. In other embodiments, such as. Figure 21 The first limiting portion 123 can also be fixedly connected to the connecting section 122 along the axial direction of the connecting member 12, and the first abutting portion 12311 can be located at the connection between the first limiting surface 1231 and the connecting section 122 along the radial direction of the connecting member 12. It should be noted that due to the limitations of manufacturing process and manufacturing cost, the connection between the first limiting surface 1231 and the connecting section 121 or the connecting section 122 may have a smaller rounded corner, that is, the first abutting portion 12311 may have a smaller rounded corner. When the mounting fixture 13 contacts the first abutting portion 12311, the rounded corner of the first abutting portion 12311 does not apply a force to the mounting fixture 13 in the radial direction away from the connecting member 12. Therefore, the second abutting portion 12312 here is farther away from the first end portion 1223 than the first abutting portion 12311, and the rounded corner of the first abutting portion 12311 is not considered. In this embodiment, along the radial direction of the connecting member 12, the first abutting portion 12311 is located at the connection between the first limiting surface 1231 and the connecting section 121. In other embodiments, the first abutting portion 12311 and the connecting section 121 may be spaced apart.

[0034] Furthermore, in this embodiment, the cooling plate assembly further includes a second cold plate 14, the second cold plate 14 includes a mating portion 111, the connecting piece 12 includes a connecting section 121 and two connecting sections 122, the mating portion 111 of the first cold plate 11 is fixedly connected to one of the two connecting sections 122, and the mating portion 111 of the second cold plate 14 is fixedly connected to the other of the two connecting sections 122, so that the first flow channels 1111 of the two mating portions 111 are respectively connected to the second flow channels 1221 of the two sections, and the two connecting sections 122 are connected, so that the fluid in the first cold plate 11 flows through the mating portion 111 of the first cold plate 11 to the connecting piece 12, and then from the connecting piece 12 through the second cold plate 14. The matching portion 111 of the second cold plate 14 flows to the second cold plate 14, and the connecting member 12 includes two first limiting portions 123. It should be noted that this embodiment includes a first cold plate 11 and a second cold plate 14. The first cold plate 11 and the second cold plate 14 both include a matching portion 111, and the connecting member 12 includes a connecting section 121 and two connecting sections 122. Therefore, along the axial direction of the connecting member 12, the first limiting surface 1231 is located on a side surface of the first limiting portion 123 away from the first end portion 1223. The first end portion 1223 here refers to the first end portion 1223 that is closer to the first limiting portion 123, and the first limiting portion 123 is arranged along the circumference of the connecting member 12.

[0035] This article focuses on improving the structure of the connecting member 12, which will be described in detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] Please refer to Figure 1-Figure 5 、 Figure 9The first embodiment shown in the figure specifically discloses that along the axial direction of the connecting member 12, the second abutting portion 12312 is farther from the first end portion 1223 than the first abutting portion 12311, and along the radial direction of the connecting member 12 away from the connecting member 12, the distance between the first limiting surface 1231 and the first end portion 1223 gradually increases, and the connecting member 12 includes a connecting section 121 and two connecting sections 122. Along the axial direction of the connecting member 12, one of the two connecting sections 122 is located on one side of the connecting section 121, and the other of the two connecting sections 122 is located on the other side of the connecting section 121. Along the radial direction of the connecting member 12, the outer side of the connecting section 122 is The diameter is greater than the outer diameter of the connecting section 121, the first limiting portion 123 is continuously arranged along the circumference of the connecting member 12, the connecting member 12 includes two first limiting portions 123, along the axial direction of the connecting member 12, one of the two first limiting portions 123 is connected to one of the two connecting sections 122, and the other of the two first limiting portions 123 is connected to the other of the two connecting sections 122, the connecting section 121 includes a first circumferential surface 1211, along the radial direction of the connecting member 12, the first circumferential surface 1211 is located on the outer periphery of the connecting section 121, the connecting section 122 includes a second circumferential surface 1222, the second circumferential surface 1222 is located on the outer periphery of the connecting section 122, along the connecting member 1 2, one side of the first limiting surface 1231 is connected to the first circumferential surface 1211, and the other side of the first limiting surface 1231 is connected to the second circumferential surface 1222. Along the radial direction of the connecting member 12, the outer diameter of the connecting section 122 is greater than the outer diameter of the connecting section 121. Since the outer diameter of the connecting section 122 is greater than the outer diameter of the connecting section 121, at the connection between the connecting section 121 and the connecting section 122, the outer side surface of the connecting member 12 extends outward along the radial direction of the connecting member 12. Since one side of the first limiting surface 1231 is connected to the first circumferential surface 1211, and the other side of the first limiting surface 1231 is connected to the second circumferential surface 1222, the first limiting surface 12 31 The first abutment portion 12311 and the second abutment portion 12312 play a limiting role while connecting the first circumferential surface 1211 and the second circumferential surface 1222. Therefore, in this embodiment, the first limiting portion 123 can be set at the connection between the connecting section 121 and the connecting section 122, and the first limiting surface 1231 connecting the first circumferential surface 1211 and the second circumferential surface 1222 is set to include the first abutment portion 12311 and the second abutment portion 12312, so that the connecting member 12 can play a limiting role for the installation fixture 13, with fewer changes to the connecting member 12 and less material consumption. At the same time, there is no limit on the size of the installation fixture 13.

[0038] Of course, in other embodiments, the first limiting portion 123 may also be arranged along the circumferential spacing of the connecting member 12 .

[0039] Reference Figure 6-Figure 8Alternatively, along the axial direction of the connecting member 12 , the distance between the second abutting portion 12312 and the first end portion 1223 may be the same as the distance between the first abutting portion 12311 and the first end portion 1223 , and the first limiting surface 1231 may be a plane.

[0040] Example 2

[0041] Please refer to Figure 1 、 Figure 2 、 Figures 9-12 The second embodiment shown in the figure specifically discloses that along the axial direction of the connecting member 12, the second abutting portion 12312 is farther from the first end portion 1223 than the first abutting portion 12311, and along the radial direction of the connecting member 12 away from the connecting member 12, the distance between the first limiting surface 1231 and the first end portion 1223 gradually increases, and the connecting member 12 includes a connecting section 121 and two connecting sections 122. Along the axial direction of the connecting member 12, one of the two connecting sections 122 is located on one side of the connecting section 121, and the other of the two connecting sections 122 is located on the side of the connecting section 121. On the other side, along the radial direction of the connector 12, the outer diameter of the connecting section 122 is greater than the outer diameter of the connecting section 121, and the first limiting portion 123 is continuously arranged along the circumference of the connector 12. The connector 12 includes two first limiting portions 123. Along the axial direction of the connector 12, the connecting section 122 and the first limiting portion 123 are spaced apart. In this embodiment, the connecting section 122 and the first limiting portion 123 are spaced apart. The first limiting portion 123 is located in the connecting section 121. Since two first limiting portions 123 are included in this embodiment, the distance between the two first limiting portions 123 is reduced. Before the limiting portion 123 acts to limit the installation fixture 13, the distance that the installation fixture 13 moves axially along the connecting piece 12 is reduced, thereby reducing the probability of eccentricity between the first limiting portion 123 and the first cold plate 11 and / or the second cold plate 14, thereby improving the connection sealing effect of the connecting piece 12. Along the radial direction of the connecting piece 12, the outer diameter of the connecting section 122 is greater than the outer diameter of the connecting section 121, the outer diameter of the first limiting portion 123 is greater than the outer diameter of the connecting section 121, the first circumferential surface 1211 is connected to the second circumferential surface 1222, and the outer diameter of the connecting section 122 is greater than the outer diameter of the connecting section 121 along the radial direction of the connecting piece 12. The outer diameter of the connecting section 121 is larger than the outer diameter of the connecting section 121. Therefore, when the installation fixture 13 clamps the connecting piece 12 and the sliding phenomenon occurs, the first limiting surface 1231 of the first limiting portion 123 abuts against the installation fixture 13, and the first limiting portion 123 limits the installation fixture 13, thereby reducing the probability of eccentricity between the connecting piece 12 and the first cold plate 11 and / or the second cold plate 14 when the installation fixture 13 clamps the connecting piece 12 and installs it with the first cold plate 11 and / or the second cold plate 14, thereby improving the connection sealing effect of the connecting piece 12.

[0042] Reference Figure 17In other embodiments, the first limiting portion 123 can be set along the circumferential spacing of the connecting member 12.

[0043] Reference Figure 13-15 In other embodiments, the distance between the second abutting portion 12312 and the first end portion 1223 may be the same as the distance between the first abutting portion 12311 and the first end portion 1223 along the axial direction of the connecting member 12, and the first limiting surface 1231 may be a plane.

[0044] Example 3

[0045] Please refer to Figure 1 、 Figure 2 、 Figure 9 、 Figures 18-20The third embodiment shown in the figure specifically discloses that along the axial direction of the connecting member 12, the second abutting portion 12312 is farther from the first end portion 1223 than the first abutting portion 12311, and along the radial direction of the connecting member 12 away from the connecting member 12, the distance between the first limiting surface 1231 and the first end portion 1223 gradually increases, and the connecting member 12 includes a connecting section 121 and two connecting sections 122. Along the axial direction of the connecting member 12, one of the two connecting sections 122 is located on one side of the connecting section 121, and the other of the two connecting sections 122 is located on the other side of the connecting section 121. Along the radial direction of the connecting member 12, the outer diameter of the connecting section 122 is greater than the outer diameter of the connecting section 121. The connecting member 12 includes multiple first limiting portions 123. , along the axial direction of the connecting member 12, the connecting section 122 and the first limiting portion 123 are spaced apart. Since two first limiting portions 123 are included in this embodiment, the distance between the two first limiting portions 123 is reduced. Before the first limiting portion 123 plays a limiting role on the mounting fixture 13, the distance the mounting fixture 13 moves along the axial direction of the connecting member 12 is reduced, thereby reducing the probability of eccentricity between the first limiting portion 123 and the first cold plate 11 and / or the second cold plate 14, thereby improving the connection and sealing effect of the connecting member 12. Along the radial direction of the connecting member 12, the outer diameter of the connecting section 122 is greater than the outer diameter of the connecting section 121, the outer diameter of the first limiting portion 123 is greater than the outer diameter of the connecting section 121, and the first circumferential surface 1211 is connected to the second circumferential surface 1222. Since the outer diameter of the connecting section 122 is larger than the outer diameter of the connecting section 121 along the radial direction of the connecting piece 12, and the outer diameter of the first limiting portion 123 is larger than the outer diameter of the connecting section 121, when the installation clamp 13 clamps the connecting piece 12 and slides, the first limiting surface 1231 of the first limiting portion 123 abuts against the installation clamp 13, and the first limiting portion 123 limits the installation clamp 13, thereby reducing the probability of eccentricity between the connecting piece 12 and the first cold plate 11 and / or the second cold plate 14 when the installation clamp 13 clamps the connecting piece 12, thereby improving the connection sealing effect of the connecting piece 12, and the first limiting portion 123 is arranged in a circumferential fan shape along the circumference of the connecting piece 12. It should be noted that this The circumferential fan-shaped arrangement along the connecting member 12 means that the first limiting portion 123 is not closed in the circumferential direction of the connecting member 12, and the first surface is defined to be perpendicular to the axial direction of the connecting member 12. The projections of at least two first limiting portions 123 on the first surface do not overlap. Since the mounting fixture 13 contacts a partial area of ​​the first circumferential surface 1211 when clamping the connecting member 12, in this embodiment, the first limiting portion 123 is arranged in a circumferential fan-shaped manner along the connecting member 12, and the projections of at least two first limiting portions 123 on the first surface do not overlap, that is, for one first limiting portion 123, there is an area along the circumference of the connecting member 12 that allows the mounting fixture 13 to pass through. Therefore, when the mounting fixture 13 clamps the connecting member 12 and installs it on the first cold plate 11 and / or the second cold plate 14,The position of the corresponding first limiting portion 123 can be selected according to the size of the mounting fixture 13 along the axial direction of the connecting member 12. Specifically, when the size of the mounting fixture 13 along the axial direction of the connecting member 12 is small, the connecting member 12 is rotated along the circumference of the connecting member 12 so that the first limiting member on the connecting member 12 farther from the connecting section 122 abuts against the mounting fixture 13. When the size of the mounting fixture 13 along the axial direction of the connecting member 12 is large, the connecting member 12 is rotated along the circumference of the connecting member 12 so that the first limiting member on the connecting member 12 farther from the connecting section 122 abuts against the mounting fixture 13. The first limiting member 123 that is closer to the mounting fixture 13 abuts against the mounting fixture 13. The corresponding first limiting portion 123 that abuts against the mounting fixture 13 can be selected based on the size of the mounting fixture 13. This allows the first limiting portion 123 to limit the mounting fixture 13 and reduces the distance that the mounting fixture 13 moves axially along the connector 12 before the first limiting portion 123 abuts against the mounting fixture 13. This reduces the probability of eccentricity between the connector 12 and the first cold plate 11 and / or the second cold plate 14, thereby improving the connection and sealing effect of the connector 12.
