[0002] With the rapid development of electronic technology and artificial intelligence (AI), servers are widely used in high-density, high-power, and high-efficiency devices to provide fast and powerful computing capabilities. Multiple servers are typically stacked in server racks. As server performance increases, the heat generated during operation also increases accordingly. Therefore, most server racks on the market have gradually adopted liquid cooling to dissipate heat from the servers.
[0003] However, as the power and performance requirements of servers increase, the heat dissipation efficiency of existing liquid cooling systems is gradually becoming unable to meet the large amount of heat generated by each server. Furthermore, since liquid-cooled server racks have fixed dimensions, how to further improve heat dissipation efficiency within the existing size architecture is an urgent issue that needs to be addressed.

[0036] The detailed description and technical content of this embodiment will be explained in conjunction with the following drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit this embodiment.
[0037] This embodiment provides a liquid-cooled server rack; please refer to [reference needed]. Figures 1 to 3 As shown, it includes a rack 10, at least one server 20, a liquid cooling module 30, a pair of pumps 40, and multiple infusion tubes 50. It should be noted that, for ease of description and simplification of the drawings, this disclosure and the drawings only illustrate a single server 20, but this is not intended to limit the liquid-cooled server rack of this embodiment to only a single server 20. Those skilled in the art should be able to increase the number of servers 20 and stack them based on the description and drawings, which will be stated in advance.
[0038] The frame 10 is a frame structure composed of multiple supports (not labeled) connected together. Specifically, in this embodiment, the frame 10 is mainly a rectangular frame composed of eight supports connected together, but this embodiment is not limited to this, and the shape of the frame 10 can be adjusted accordingly according to different needs. In this embodiment, multiple reinforcing ribs (not labeled) are connected between the supports of the frame 10 to enhance the overall structural strength of the frame 10, but no reinforcing ribs are provided on the front and rear sides of the frame 10, so that users can conveniently install internal components and perform maintenance on the front or rear side of the frame 10. Multiple decorative panels (not labeled) are connected to the left, right, top, and bottom sides of the frame 10 to close the top, bottom, left, and right sides of the frame 10. At least one door panel (not labeled) is pivotally connected to the front and rear sides of the frame 10, but this embodiment is not limited to this.
[0039] Server 20 is disposed within rack 10. Specifically, server 20 may be placed on rails, shelves, or support frames installed within rack 10; this embodiment does not impose further limitations on this. In this embodiment, server 20 has a pair of opposing first spaces 101 and a pair of opposing second spaces 102 formed around its four sides (i.e., left, right, front, and rear) and rack 10, respectively. However, this embodiment is not limited to this; for example, server 20 may also rest against one side of rack 10. Specifically, each first space 101 is located on one of the opposing sides (left and right) of server 20, while each second space 102 is located on the other opposing sides (front and rear) of server 20.
[0040] The liquid cooling module 30 is housed within the rack 10 and includes a liquid distribution unit 31, a cooling distribution manifold (CDM) 32, an outlet manifold 33, an inlet pipe 34, and an outlet pipe 35. The liquid distribution unit 31 is a cooling distribution unit (CDU) used to regulate and control the flow rate of the coolant to maintain the required temperature and flow rate of the liquid cooling system. In this embodiment, the liquid distribution unit 31 is located below the server 20, but this embodiment is not limited to this. Both the inlet manifold 32 and the outlet manifold 33 are cooling distribution manifolds (CDMs). The inlet manifold 32 is used to distribute the coolant to each server 20 for heat dissipation and cooling, while the outlet manifold 33 collects and merges the coolant absorbed by each server 20. Specifically, the inlet pipe 34 connects the liquid distribution device 31 and the inlet manifold 32, while the outlet pipe 35 connects the liquid distribution device 31 and the outlet manifold 33. Therefore, the coolant first flows through the inlet pipe 34 to the inlet manifold 32 by the liquid distribution device 31, then is distributed to each server 20 by the inlet manifold 32, and then flows back to the outlet manifold 33, finally returning to the liquid distribution device 31 through the outlet manifold 33 via the outlet pipe 35 to form a cycle.
[0041] One pump 40 is located in the inlet pipe 34 and is connected to both the liquid distribution device 31 and the inlet manifold 32. The other pump 40 is located in the outlet pipe 35 and is connected to both the liquid distribution device 31 and the outlet manifold 33. Thus, the pump 40 in the inlet pipe 34 further propels the coolant flowing from the liquid distribution device 31, accelerating its entry into the inlet manifold 32 for distribution, thereby increasing the flow rate of coolant into each server 20 and significantly increasing the heat dissipation efficiency of each server 20. Furthermore, the pump 40 in the outlet pipe 35 further propels the coolant flowing from the outlet manifold 33, accelerating its entry into the liquid distribution device 31, thereby mitigating the problem of reduced coolant flow rate due to confluence in the outlet manifold 33 and significantly improving the coolant return rate.
[0042] Each portion of the infusion pipe 50 is connected at both ends to the inlet manifold 32 and the server 20, respectively, while the remaining portions of the infusion pipe 50 are connected at both ends to the outlet manifold 33 and the server 20, respectively. Thus, the server 20 is connected to the inlet manifold 32 and the outlet manifold 33 via the infusion pipes 50, allowing coolant to flow from the inlet manifold 32 through the infusion pipes 50 into the server 20 for cooling, and then through the remaining infusion pipes 50 into the outlet manifold 33. In this embodiment, the number of infusion pipes 50 connecting a single server 20 to the inlet manifold 32 and the number of infusion pipes 50 connecting the same server 20 to the outlet manifold 33 are both five. However, this embodiment is not limited to this; the number and placement of the infusion pipes 50 can be adjusted according to different needs to optimally dissipate heat from one or more heat sources inside the server 20.
[0043] Please see Figure 1 and Figure 2 As shown, in this embodiment, the pump 40 installed on the inlet pipe 34 is connected in series with the inlet pipe 34, and the pump 40 installed on the outlet pipe 35 is connected in series with the outlet pipe 35, thereby simplifying the structure and reducing the cost of the inlet pipe 34 and the outlet pipe 35. However, this embodiment is not limited thereto. For example, such as Figure 3 As shown, the pump 40 installed on the inlet pipe 34 can also be connected in parallel to the inlet pipe 34, or the pump 40 installed on the outlet pipe 35 can also be connected in parallel to the outlet pipe 35, thus facilitating the installation and removal of the pump 40. Specifically, each pump 40 includes a body 41 and a pair of clamps 42. In each pump 40, both ends of the body 41 are connected to the corresponding inlet pipe 34 or outlet pipe 35, and each clamp 42 is respectively installed at the connection between the body 41 and the corresponding inlet pipe 34 or outlet pipe 35, thereby firmly fixing the body 41 to the inlet pipe 34 or outlet pipe 35.
[0044] To further explain, the inlet manifold 32 and the outlet manifold 33 are located on opposite sides of the liquid dispensing device 31. Specifically, since the liquid dispensing device 31 in this embodiment is located below the server 20, the inlet manifold 32 and the outlet manifold 33 are located within the first spaces 101 on the left and right sides of the server 20, respectively. Neither the inlet manifold 32 nor the outlet manifold 33 protrudes from the front or rear sides of the server 20, thereby saving space and facilitating space configuration. However, this embodiment is not limited to this. Furthermore, each infusion pipe 50 is located within one of the second spaces 102, that is, each infusion pipe 50 is located on the front or rear side of the server 20. Since the inlet manifold 32 and the outlet manifold 33 are located within the first spaces 101 on the left and right sides of the server 20, the bending radius of each infusion pipe 50 due to its own flexibility can be avoided, thus preventing an increase in the lateral width or longitudinal depth of the liquid-cooled server cabinet.
[0045] In this embodiment of the liquid-cooled server cabinet, each pump 40 is respectively installed in the inlet pipe 34 and the outlet pipe 35. One pump 40 is connected to the liquid distribution device 31 and the inlet manifold 32, and the other pump 40 is connected to the liquid distribution device 31 and the outlet manifold 33. Therefore, the liquid-cooled server cabinet in this embodiment can accelerate the flow rate of the coolant through each pump 40, thereby improving the overall heat dissipation efficiency.
[0046] In summary, the foregoing disclosure of this utility model is intended to enable those skilled in the art to clearly understand the technical content of this utility model and implement it accordingly, and is not intended to limit the scope of patent protection of this utility model. In addition, this utility model may have other embodiments not listed. Without departing from the spirit and essence of this utility model, those skilled in the art should be able to devise various corresponding changes and modifications based on this utility model, but all such changes and modifications should fall within the scope of protection of the patent application filed for this utility model.
