The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0026] like Figure 1-5As shown, the first aspect of this utility model provides a flow guiding structure for a server 20, wherein a heat dissipation mesh plate is provided at the bottom of the server 20; it includes a flow guiding shroud 10 and a flow guiding component 30, wherein the flow guiding shroud 10 is disposed at the bottom of the server 20 and the inner cavity of the flow guiding shroud 10 communicates with the interior of the server 20, and the flow guiding shroud 10 is used to deliver coolant from the bottom of the server 20 through the heat dissipation mesh plate to the interior of the server 20;

[0027] The flow guide 30 is disposed in the inner cavity of the flow guide cover 10. The flow guide 30 includes a liquid supply pipe 31 and a plurality of flow guide pipes 32 respectively communicating with the liquid supply pipe 31. Each flow guide pipe 32 is provided with a plurality of sub-flow guide pipes 33. Each sub-flow guide pipe 33 is provided with a flow guide hole 331, and the flow guide hole 331 is located close to the bottom surface of the server 20. The liquid inlet end 311 of the liquid supply pipe 31 extends out of the flow guide cover 10. The flow guide 30 is used to guide the coolant through the liquid supply pipe 31, the flow guide pipes 32, the sub-flow guide pipes 33 and the flow guide hole 331 to a preset position inside the server 20. The preset position may be the location of a high-power heat-generating component inside the server, such as the location of a graphics processing unit (GPU), with the sub-flow guide pipes 33 arranged below the graphics processor.

[0028] In some embodiments, the flow guide 10 is a rectangular frame structure; however, in optional embodiments, the flow guide 10 can also be other shapes. The flow guide 10 includes sidewalls surrounding the bottom of the server 20, forming an inner cavity of the flow guide 10. The top opening of the inner cavity forms a first liquid outlet, and the bottom opening of the inner cavity forms a first liquid inlet. The first liquid outlet communicates with the interior of the server 20, and the first liquid inlet communicates with a coolant source. In actual use, a base plate can be provided at the bottom of the sidewall of the flow guide 10, closing the bottom opening of the sidewall of the flow guide 10. A liquid inlet cavity is provided inside the base plate, and a liquid inlet communicating with the liquid inlet cavity is provided on the side of the base plate. Multiple openings are provided at the top of the base plate to allow coolant to flow into the flow guide 10. Of course, in optional embodiments, other liquid inlet structures can also be provided at the bottom of the sidewall of the flow guide 10 to guide coolant into the inner cavity of the flow guide 10.

[0029] In some embodiments, a seal is further provided between the top surface of the sidewall of the flow deflector 10 and the bottom surface of the server, the seal being used to seal the gap between the top surface of the sidewall of the flow deflector 10 and the bottom surface of the server. The seal may be a sealing ring, effectively preventing fluid leakage and ensuring a sealing effect.

[0030] In some embodiments, the flow deflector 10 is provided with mounting members 40 at both ends along its length. One end of the mounting member is used to connect to the server 20, and the other end of the mounting member 40 is connected to the sidewall of the flow deflector. Specifically, as shown... Figure 5 As shown, the mounting component 40 includes a first side plate and a second side plate. The first side plate is attached to the side wall of the server 20 and fixedly connected with screws. The second side plate is attached to the side wall of the air deflector 10 and fixedly connected with screws. The mounting component 40 facilitates the installation and removal of the air deflector 10, improving assembly and maintenance efficiency. When it is necessary to replace or maintain the air deflector 10, it can be easily detached from the server 20.

[0031] In some embodiments, a fixing plate 41 is further included, which is mounted on the first side plate. The fixing plate 41 has a first limiting hole extending along the width direction of the flow guide 10, and the first side plate has a second limiting hole extending along the height direction of the flow guide 10. Limiting elements are disposed within the first and second limiting holes. The fixing plate 41 and the first side plate also have corresponding through holes, and connecting elements are disposed within the through holes. This ensures the positional accuracy of the flow guide after installation, allowing it to stably cooperate with the server, thereby improving the reliability and performance of the entire system.

[0032] In some embodiments, the liquid supply pipe 31 extends along the width direction of the flow guide shroud 10, and the liquid supply pipe 31 is cross-connected with a plurality of flow guide pipes 32 respectively; the two ends of the flow guide pipe 32 are closed and fixedly connected to the inner wall of the flow guide shroud 10.

[0033] In some embodiments, each of the guide pipes 32 extends along the length direction of the guide shroud 10, and the plurality of guide pipes 32 are spaced apart along the width direction of the guide shroud 10; the plurality of sub-guide pipes 33 are spaced apart along the axial direction of the guide pipes 32, each sub-guide pipe 33 extends along the height direction of the guide shroud 10, and the top of the sub-guide pipe 33 is provided with the guide hole 331. The diameter of the supply pipe 31 is larger than the diameter of the guide pipe 32, and the diameter of the guide pipe 32 is larger than the diameter of the sub-guide pipe 33. The larger diameter of the supply pipe can provide sufficient cross-sectional area, allowing the coolant to flow at a lower flow rate within the supply pipe, thereby ensuring sufficient flow to each branch guide pipe 32 to meet the supply requirements of each guide pipe 32.

[0034] In some embodiments, both ends of the flow guide tube 32 are provided with connecting portions, and the inner wall of the flow guide shroud 10 is provided with a hooking portion that matches the connecting portion. The connecting portion and the hooking portion are hooked together to fix the flow guide structure to the flow guide shroud 10.

[0035] In some embodiments, the mounting portion is a support plate 51 provided on the inner wall of the flow guide shroud 10, and the support plate 51 is provided with a first connecting hole; the connecting portion is a suspension plate 50 provided at the end of the flow guide tube 32, and the suspension plate 50 is provided with a second connecting hole corresponding to the first connecting hole; fasteners are provided in the first connecting hole and the second connecting hole to fix the suspension plate 50 to the support plate 51. By providing the support plate 51 and the suspension plate 50, the installation and removal of the flow guide 30 within the flow guide shroud 10 are facilitated, improving the efficiency of assembly and maintenance. When it is necessary to replace the flow guide 30 or to maintain the flow guide 30, it can be easily separated from the flow guide shroud 10.

[0036] A second aspect of this utility model also provides a server, including a housing and a flow guiding structure as provided in the first aspect of this utility model, the flow guiding structure being disposed at the bottom of the housing.

[0037] This invention divides the coolant entering the server into two paths through a guide shroud and a guide component. One path of coolant enters the server from the bottom through the guide shroud, thereby dissipating heat from the entire server. The other path of coolant enters from the inlet end of the guide component and flows out through the guide hole to a preset position inside the server. The preset position is the assembly position of the high-power heat-generating element, thus enabling more precise heat dissipation for the high-power heat-generating element while dissipating heat from the server.

[0038] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
