TECHNICAL FIELD
[0001] The present application relates to the technical field of liquid cooling, in particular to an immersion liquid cooling cabinet. BACKGROUND
[0002] The immersion liquid cooling cabinet is an advanced heat dissipation solution, especially suitable for high-performance computing (HPC), data centers and other applications that require efficient heat dissipation. In this cooling method, electronic devices such as servers and processors are directly immersed in a special cooling liquid, and the cooling liquid has insulation properties and can safely contact electronic devices without causing short circuits.
[0003] The immersion liquid cooling cabinet currently used by the data center immersion liquid cooling system is composed of an internal immersion cabinet and a shell. The internal cabinet is used to carry the cooling liquid and place the servers, and the shell supports the internal cabinet. The original shell usually needs to be welded with a load-bearing frame, which is composed of multiple load-bearing beams, and then the internal immersion cabinet is supported in the load-bearing frame and welded with the load-bearing frame.
[0004] However, this structure has the following problems. First, the immersion liquid cooling cabinet needs to carry a large amount of cooling liquid and heavy server equipment, so the design of the load-bearing frame must have high load-bearing capacity. In order to meet this requirement, the traditional design often uses more number and heavy steel to ensure the structural strength, which increases the weight of the entire immersion liquid cooling cabinet and affects transportation, installation and maintenance.
[0005] Secondly, multiple load-bearing beams need to be welded with the immersion cabinet. Due to the large number of welding points between multiple beams and the uneven distribution and welding quality of the load-bearing beams, the overall load cannot be evenly distributed, and the local area bears too much force. This may cause deformation of the immersion cabinet and the load-bearing frame, thereby affecting the stability of the cabinet and the normal operation of the equipment. INVENTION CONTENTS
[0006] In order to realize uniform stress of the liquid cooling cabinet, enhance the load-bearing capacity of the liquid cooling cabinet, and reduce the weight of the liquid cooling cabinet, the present application provides an immersion liquid cooling cabinet.
[0007] The immersion liquid cooling cabinet provided by the present application adopts the following technical scheme:
[0008] An immersion liquid cooling cabinet, comprising an inner container, a connecting rib is arranged on the outer side wall of the inner container, a thin plate skin is connected to the side of the connecting rib away from the inner container, the thin plate skin surrounds the inner container, a foaming layer is arranged between the thin plate skin and the inner container, and a filling hole for foaming is formed in the thin plate skin.
[0009] By adopting the technical scheme, the load-bearing structure of the immersion liquid cooling cabinet is optimized, the foaming layer reduces the dependence on the load-bearing beams while ensuring the structural strength of the liquid cooling cabinet, so that a large amount of heavy steel is not needed, and lighter and smaller steel ribs can be used instead, which effectively reduces the overall weight of the cabinet.
[0010] Compared with the complex welding structure of the traditional design requiring multiple thick beams and girders, the scheme provides additional support and stability through the foaming layer, allows the number and thickness of the connecting ribs to be reduced, thereby reducing multiple welding points, and due to the filling of the foaming layer, the load can be uniformly distributed between the connecting ribs, the thin plate skin and the inner container, avoiding the deformation or damage caused by the load concentrated in the local area in the traditional welding structure, so that the liquid cooling cabinet is uniformly stressed and its load-bearing capacity is improved.
[0011] Meanwhile, the foaming layer has a certain elasticity and buffering effect, enhances the anti-seismic capacity of the cabinet under earthquakes or other impacts, and reduces the stress concentration problem caused by equipment vibration;
[0012] In addition, the design of the foaming layer also plays a role in strengthening heat insulation, reducing heat loss, flame retardation and noise reduction, etc.
[0013] Optionally, the connecting ribs include longitudinal ribs, the longitudinal ribs are arranged at the corners of the liquid cooling cabinet, the longitudinal ribs serve as connecting columns of two vertically arranged and mutually perpendicular thin plate skins, a plurality of transverse ribs are connected between adjacent two longitudinal ribs, and the longitudinal ribs and the transverse ribs are welded with the inner container and the thin plate skin.
[0014] By adopting the technical scheme, the arrangement of the ribs meets the bearing requirements and is simple and convenient for production.
[0015] Optionally, the transverse rib spacing is 200-600mm.
[0016] By adopting the technical scheme, for a thin plate skin with a thickness of 1-2mm, the transverse rib spacing is controlled to be 300-500mm, at which time the distribution of the foaming pressure and the structural strength can be considered;
[0017] For a thin plate skin with a thickness of 2-3mm, the transverse rib spacing can be appropriately increased to 400-600mm, and since the skin is thicker, it has better anti-deformation capacity;
[0018] In the case of higher structural strength requirements, the transverse rib spacing can be appropriately reduced, for example, 200-300mm, to enhance the overall anti-deformation capacity;
[0019] By reasonable rib spacing distribution, the weight can be reduced under the premise of ensuring the strength of the cabinet, and the deformation of the thin plate skin caused by too large rib spacing is avoided.
[0020] Optionally, the filling holes are arranged at intervals of 100-500 mm.
[0021] By adopting the above technical scheme, the interval of the filling holes can be about 100-200 mm for a 1-2 mm thick thin plate skin to ensure that the foaming material can be uniformly filled;
[0022] For a 2-3 mm thick thin plate skin, the thin plate skin with a large thickness has stronger anti-deformation ability, and the interval of the filling holes can be about 300-500 mm, and the number of holes in the interval is also relatively reduced while ensuring the uniform filling of the foaming layer between the thin plate skin and the inner container.
[0023] The reasonable arrangement of the filling holes ensures that the material can uniformly fill the space between the thin plate skin and the inner container during foaming, avoids the instability of the structure caused by uneven filling of the material, and prevents the deformation of the thin plate skin caused by uneven pressure during foaming.
[0024] Optionally, one end of the transverse rib is provided with a gas permeable hole.
[0025] By adopting the above technical scheme, during foaming, the foaming agent is first injected from the filling hole far from the gas permeable hole, and then gradually foamed to the filling hole close to the gas permeable hole. In this process, the gas between the thin plate skin and the inner container is gradually discharged from the filling hole and the gas permeable hole. When the last filling hole is filled with the foaming agent, the gas can also be discharged from the gas permeable hole into the unfilled space and then from the unfilled filling hole, reducing the formation of bubbles or uneven filling in the foaming layer.
[0026] Optionally, the transverse rib located at the bottom of the liquid cooling cabinet is connected with a flow guide plate, the flow guide plate is arranged close to the gas permeable hole, and a channel for the foaming agent to pass through is left between the flow guide plate and the opposite thin plate skin.
[0027] By adopting the above technical scheme, the design of the flow guide plate helps to guide the flow of the foaming agent. The foaming agent can first be concentrated on the side away from the gas permeable hole, and then gradually filled in the direction close to the gas permeable hole, ensuring that the foaming agent can be uniformly distributed between the two adjacent transverse ribs, and guiding the excess gas to be discharged, further improving the filling quality and uniformity of the foaming layer at the bottom of the cabinet.

[0029] By adopting the above technical scheme, the cooling liquid can flow into the inner container from the liquid inlet embedded pipe, the cooling liquid completing heat exchange is discharged to the liquid return cavity from the liquid overflow port, and then discharged to the cooling system through the liquid outlet embedded pipe. The liquid outlet embedded pipe and the liquid inlet embedded pipe are welded first, and then the foaming layer seals the gap around the pipe, thereby improving the anti-seepage effect.
[0030] Optionally, the filling hole is welded with a sealing plate, and the sealing plate is matched with the filling hole.
[0031] By adopting the above technical scheme, the design of the sealing plate can effectively close the filling hole after foaming is completed, thereby ensuring the integrity of the cabinet structure and preventing the external environment from affecting the foaming layer.
[0032] Optionally, the foaming layer can be polyurethane / polystyrene / polypropylene.
[0033] By adopting the above technical scheme, these materials have good insulation, impact resistance and corrosion resistance, and are suitable for use in liquid cooling cabinets. At the same time, the diversity of foaming materials provides flexible selection for different application scenarios, and the material properties can be adjusted according to the requirements.
[0034] In summary, the present application has at least one of the following beneficial technical effects:
[0035] 1. The foaming layer reduces the dependence on the load-bearing beam while ensuring the structural strength of the liquid cooling cabinet, so that a large amount of heavy steel material is not needed, and a lighter and smaller steel rib can be used instead, which effectively reduces the overall weight of the cabinet;
[0036] 2. Compared with the complex welding structure of multiple thick beams and girders in the traditional design, the present application provides additional support and stability through the foaming layer, allowing the number and thickness of the connecting ribs to be reduced, thereby reducing multiple welding points.

The side, away from the inner container 1, of the longitudinal rib 31 and the transverse rib 32 is welded with a sheet skin 4, the longitudinal rib 31 serves as a connecting beam of two vertically arranged and perpendicular sheet skins 4, the thickness of the sheet skin 4 can be 1-3 mm, the thickness of the sheet skin 4 in the embodiment of the application is 2 mm, and the spacing of the transverse ribs 32 can be 200-600 mm, and the spacing of the transverse ribs 32 in the embodiment of the application is 450 mm.
[0051] As Figure 4 and Figure 5 A plurality of filling holes 41 are arranged on the sheet skin 4, the filling holes 41 are arranged in a plurality of rows and a plurality of columns at equal intervals, the filling holes 41 are located between the two adjacent transverse ribs 32, the filling holes 41 between the two adjacent transverse ribs 32 are arranged at equal intervals along the length direction of the transverse rib 32, and the spacing of the filling holes 41 between the two adjacent transverse ribs 32 is 100-500 mm, and in the embodiment of the application, the spacing of the filling holes 41 is 250 mm. The filling hole 41 is welded with a sealing plate 42, and the sealing plate 42 is matched with the filling hole 41. One end of the transverse rib 32 is provided with a gas permeable hole 321, the transverse rib 32 located at the bottom of the liquid cooling cabinet is connected with a flow guide plate 33, the flow guide plate 33 is arranged close to the gas permeable hole 321, and a channel for the foaming agent to pass through is left between the flow guide plate 33 and the sheet skin 4 opposite to the flow guide plate 33, and the flow guide plate 33 is perpendicular to the transverse rib 32. A foaming layer 5 is filled between the sheet skin 4 and the inner container 1, and the material of the foaming layer 5 can be polyurethane / polystyrene / polypropylene.
[0052] The side of the sheet skin 4 and the inner container 1 is provided with a liquid inlet embedded pipe 6 and a liquid outlet embedded pipe 7, the liquid inlet embedded pipe 6 and the liquid outlet embedded pipe 7 are welded to the sheet skin 4 and the inner container 1, the liquid outlet embedded pipe 7 is communicated with the liquid return cavity 22, and the liquid inlet embedded pipe 6 passes through the liquid return baffle 2 to the liquid holding space of the inner container 1.
[0053] The cooling liquid can flow into the inner container 1 from the liquid inlet embedded pipe 6, the cooling liquid completing heat exchange is discharged to the liquid return cavity 22 from the liquid overflow port 21, and then is discharged to the cooling system through the liquid outlet embedded pipe 7. The liquid outlet embedded pipe 7 and the liquid inlet embedded pipe 6 are welded first, and then the foaming layer 5 seals the gap around the pipe, thereby improving the anti-seepage effect.
[0054] During foaming, the foaming agent is first injected from the filling hole 41 far away from the air vent 321, and then gradually injected into the filling hole 41 close to the air vent 321.

Therefore, a large amount of heavy steel material is not required, and a lighter and smaller steel rib can be used instead, which effectively reduces the overall weight of the cabinet.
[0057] Compared with the complex welding structure of multiple thick beams and girders in the traditional design, the scheme provides additional support and stability through the foaming layer 5, allowing the number and thickness of the connecting ribs 3 to be reduced, thereby reducing multiple welding points. Due to the filling of the foaming layer 5, the load can be evenly distributed between the connecting ribs 3, the thin plate skin 4, and the inner container 1, avoiding the deformation or damage caused by the load concentrated in a local area in the traditional welding structure. This makes the liquid cooling cabinet bear force evenly and improves its load-bearing capacity.
[0058] It should be noted that the inner container 1 also has a card slot block (not shown in the figure) corresponding to the plug-in server and an optical fiber bundle (not shown in the figure) passing out of the inner container 1 and the thin plate skin 4.
