Description

Technical Field

[0001] This utility model belongs to the field of liquid-cooled server piping design technology, and in particular relates to a liquid-cooled server cooling piping with a positioning pin. Background Technology

[0002] Liquid-cooled servers utilize liquid as a cooling medium, directly absorbing and transferring heat generated during operation through liquid flow. The core principle involves introducing coolant into the server through pipes, where heat exchange occurs through direct contact between the thermally conductive liquid and the heat-generating components, ultimately dissipating heat through an external circulation system. Current technology involves multiple server stacks and liquid cooling piping. These stacks need to be layered onto the piping. Currently, installation typically involves pre-installing locating pins onto a base plate (the base plate's length is equal to the liquid cooling piping length), welding the liquid cooling piping connectors to a long strip plate, and finally welding the plate to the piping. This process then allows for the subsequent assembly of each server stack, guided by the locating pins, with each component connected to the piping. Therefore, this assembly method is not only inefficient and costly, but also compromises the overall structural quality. Utility Model Content

[0045] Please see Figures 1 to 11 This utility model discloses a liquid-cooled server cooling pipe with a positioning pin 4, which includes:

[0046] Pipe body 1, wherein the pipe body 1 has a plurality of first interfaces along its length;

[0047] Pipe connector 2, each of the pipe connectors 2 includes a main body 21 and a flange 22 sleeved on and fixedly connected to the main body 21; each main body 21 is riveted to the first interface, and each flange 22 is located outside the first interface, and the outer diameter of the flange 22 is larger than the diameter of the first interface.

[0048] Positioning pin 4 assembly, the positioning pin 4 assembly comprising:

[0049] Support member 3, the support member 3 includes at least a first plate 31, the upper limit of the first plate 31 in the height direction of the pipeline body 1 is located between the flange portion 22 of the pipe joint 2 and the pipeline body 1, and the main body portion 21 of the pipe joint 2 passes through the first plate 31; or, the upper limit of the first plate 31 in the length direction of the pipeline body 1 is located between two adjacent pipe joints 2.

[0050] The positioning pin 4 is riveted to the first plate 31 and protrudes from the first plate 31 away from the surface of the pipe body 1; the positioning pin 4 and the pipe joint 2 are arranged sequentially at intervals along the length of the pipe body 1.

[0051] With the above arrangement, the main body 21 of each pipe connector 2 is riveted one-to-one with the first interface of the pipeline body 1 along its length, such that the flange 22 fitted onto and fixedly connected to it is located outside the corresponding first interface. In the positioning pin 4 assembly, the support member 3 includes at least a first plate 31 that is directly limited in the height direction of the pipeline body 1 between the flange 22, whose outer diameter is larger than the diameter of the first interface, and the pipeline body 1. The main body 21 of the pipe connector 2 also passes through the first plate 31, or the first plate 31 is directly limited in the length direction of the pipeline body 1 between two adjacent pipe connectors 2. The positioning pin 4 is riveted to the first plate 31 and protrudes from the first plate 31 away from the surface of the pipeline body 1. After the liquid-cooled server cooling pipeline with positioning pin 4 is assembled, the positioning pin 4 and the pipe connector 2 are still arranged alternately in the length direction of the pipeline body 1. Therefore, the liquid-cooled server cooling pipe with positioning pin 4 in this embodiment, compared with the prior art which only uses welding to connect multiple pipe joints 2, support members 3 and pipe body 1, effectively improves assembly efficiency, reduces installation cost, and ensures the overall structural quality of the final assembly.

[0052] Please see Figures 2 to 5Specifically, in the first embodiment, the pipe body 1 is rectangular in shape, and has multiple circular first interfaces on its upper end face along its length for riveting to the main body 21 of the pipe connector 2. After the main body 21 of the pipe connector 2 is riveted to the first interface, the flanges 22 fitted onto and fixedly connected to the main body 21 are all located outside the tubular body, and the outer diameter of the flanges 22 is larger than the diameter of the first interface. The positioning pin 4 assembly includes a support 3 consisting only of a long strip-shaped first plate 31, which is held in the height direction of the pipe body 1 by the end faces of the flanges 22 of the pipe connectors 2 facing the pipe body 1 and the end faces of the pipe body 1 facing the flanges 22, thereby fixing the first plate 31 to the pipe body 1. More specifically, the first plate 31 has holes for riveting with the positioning pins 4 and holes for the main body 21 of the pipe connector 2 to pass through. Since the liquid-cooled server cooling pipes with positioning pins 4 are arranged alternately along the length of the pipe body 1 after assembly, the positioning pins 4 and the pipe connector 2 are arranged alternately along the length of the pipe body 1. It should be understood that, to ensure the relative fixation of the support member 3 with the pipe body 1 and the pipe connector 2 in other directions of the pipe body 1, the holes on the first plate 31 for the main body 21 of the pipe connector 2 to pass through are clearance-fitted with the main body 21 of the pipe connector 2.

[0053] Specifically, in this embodiment, the first plate 31 is held in the height direction of the pipeline body 1 by the end faces of the flange portions 22 of the multiple pipe joints 2 facing the pipeline body 1 and the end faces of the pipeline body 1 facing the flange portions 22, thereby the first plate 31 and the pipeline body 1 are fixedly connected.

[0054] Specifically, in this embodiment, the main body 21 of the pipe connector 2 has a through cavity 23. After the main body 21 of the pipe connector 2 is riveted to the first interface on the pipe body 1, the through cavity 23 connects the interior of the pipe body 1 with external parts. The cavity wall of the through cavity 23 is provided with internal threads, thereby enabling connection with external parts. The main body 21 includes a deformation section and a riveting section 211 connected sequentially from the flange 22 toward the pipe body 1. When the pipe connector 2 is installed to the pipe body 1, the riveting section 211 is inserted into the pipe body 1, and then an external force is applied to the riveting section 211 using a riveting tool, thereby causing the deformation section to be compressed and deformed to form a stop 24 that abuts against the inner wall of the pipe body 1, thus achieving the riveting of the main body 21 to the pipe body 1.

[0055] Specifically, in this embodiment, the length of the first plate 31 in the longitudinal direction of the pipe body 1 is equal to the length of the pipe body 1; the width of the first plate 31 in the width direction of the pipe body 1 is equal to the width of the pipe body 1, thereby facilitating the alignment and adaptation of the first plate 31 with the pipe body 1. Of course, in other embodiments, the length of the first plate 31 in the longitudinal direction of the pipe body 1 may also be less than the length of the pipe body 1; the width of the first plate 31 in the width direction of the pipe body 1 may also be less than the width of the pipe body 1, for example, in the second and third embodiments, such as... Figure 8 and Figure 9 As shown, the length of each first plate 31 in the longitudinal direction of the pipeline body 1 is less than the length of the pipeline body 1. In the third embodiment, the width of each first plate 31 in the width direction of the pipeline body 1 is slightly less than the width of the pipeline body 1.

[0056] Specifically, in this embodiment, a connecting section 25 is provided between the flange portion 22 and the deformation portion. The outer diameters of the flange portion 22, the connecting section 25, and the deformation section decrease sequentially. The connecting section 25 penetrates the first plate 31. After the deformation section is deformed by a riveting tool to form a stop 24 that abuts against the inner wall of the pipe body 1, the end face of the connecting section 25 facing the pipe body 1 also abuts against the outer wall of the pipe body 1. Thus, the pipe joint 2 and the pipe body 1 have a stable connection. Simultaneously, the plate around the hole in the first plate 31 through which the main body 21 of the pipe joint 2 passes is effectively clamped by the flange portion 22, the connecting section 25, and the pipe body 1. Preferably, the hole in the first plate 31 through which the main body 21 of the pipe joint 2 passes is clearance-fitted with the connecting section 25. Furthermore, a sealing groove 5 is provided on the end face of the connecting section 25 facing the pipe body 1, and a sealing strip 6 is installed in the sealing groove 5 to seal the connection between the connecting section 25 and the outer wall of the pipe body 1. Of course, in other embodiments, the sealing strip 6 can also be replaced with sealant.

[0057] Please see Figure 10 Specifically, in this embodiment, the positioning pin 4 is connected to the first plate 31 by a riveting connection. Of course, in other embodiments, the positioning pin 4 and the first plate 31 can also be connected by... Figure 11 The connection can be made by riveting or other methods as shown.

[0058] Please see Figure 1 ,as well as Figures 3 to 5 Specifically, in this embodiment, the positioning pin 4 includes a tail 41, a middle portion 42, and a head 43 sequentially arranged from the side of the first plate 31 away from the pipeline body 1; wherein, the tail 41 has a riveting structure at the end away from the middle portion 42 so as to be riveted to the first plate 31; the outer diameter of the middle portion 42 gradually decreases from the tail 41 to the head 43, while the head 43 is hemispherical, and the end face of the head 43 connected to the middle portion 42 is circular, thereby playing a positioning and guiding role in the installation process of the positioning pin 4 and the first plate 31, and can also play a positioning and guiding role in the subsequent installation of multiple server stacked components that need to be stacked on the pipeline body 1.

[0059] Please see Figures 6 to 9 Specifically, in the second and third embodiments, the upper limit of the first plate 31 in the length direction of the pipeline body 1 is located between two adjacent pipe joints 2. The plate surfaces of the first plate 31 facing the pipe joints 2 in the length direction of the pipeline body 1 are recessed inward to form a relief portion 311 to avoid the pipe joints 2. The difference is that in the second embodiment, the relief portion 311 abuts against the outer wall of the pipe joint 2, while in the third embodiment, the relief portion 311 is separated from the outer wall of the pipe joint 2.

[0060] Specifically, in the second embodiment, the support member 3 further includes a second plate 32 parallel to the first plate 31, and a third plate 33 and a fourth plate 34 perpendicular to the first plate 31; the first plate 31, the third plate 33, the second plate 32, and the fourth plate 34 are connected end to end in sequence, so that the support member 3 is sleeved on the pipe body 1. Therefore, when the support member 3 is clamped and limited by the two pipe joints 2 connected on the left and right, it will not be displaced from the pipe body 1 in other directions (front-back direction and up-down direction). In the process of assembling the liquid-cooled server cooling pipe with positioning pins 4, the positioning pins 4 can be riveted to the first plate 31 to form multiple positioning pin 4 assemblies. Then, multiple positioning pin 4 assemblies and multiple pipe joints 2 can be sequentially and cyclically assembled onto the pipe body 1 along the length direction of the pipe body 1. The pipe joints 2 and the pipe body 1 are assembled by riveting, and the positioning pin 4 assemblies are directly sleeved on the pipe body 1.

[0061] Specifically, in the third embodiment, since the avoidance part 311 is separated from the outer wall of the pipe joint 2, the first plate 31 and the pipe body 1 are fixedly connected in the height direction of the pipe body 1. For example, the first plate 31 and the pipe body 1 are connected by welding. Preferably, the welding point is relatively far away from the pipe joint 2, for example, it is arranged at both ends of the first plate 31 along the width direction of the pipe body 1.

[0062] Specifically, in the second and third embodiments, unlike the first embodiment, there is no connecting section 25 between the flange 22 and the deformation section. Therefore, the end face of the flange 22 facing the pipe body 1 is directly and sealed to the pipe body 1. For example, a sealing groove (not shown in the figure) is opened on its end face facing the pipe body 1, and a sealing strip or sealant (not shown in the figure) is installed in the sealing groove.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any changes, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
