Description

Technical Field

[0001] The present invention relates to the technical field of AI servers, and in particular to a liquid-cooled AI server. Background Art

[0002] AI servers are servers designed specifically for artificial intelligence applications. They have powerful computing, storage, and networking capabilities and are usually equipped with high-performance CPUs, GPUs, FPGAs, and other computing chips, as well as large-capacity memory and storage devices. They can provide efficient and stable computing services for artificial intelligence applications. AI servers are equipped with auxiliary radiators, which usually use cooling fans or liquid cooling. The invention with publication number CN118444761A discloses a heat dissipation device for an AI server GPU. With the help of the rotation of a reciprocating screw 1, the jet plate is driven to slide horizontally along the X-axis. The engagement of gear 2 and the rack enables the jet plate to slide along the Y-axis. With the rotation of the fan blades and the heat dissipation pipe, the GPU module can be effectively cooled from the side, top, and bottom, thereby improving the efficiency of the heated air being discharged, while also promoting the inflow of more air, further improving the overall heat dissipation effect.

[0003] Utility model publication number CN209215999U discloses an AI server with excellent heat dissipation performance. Rectangular blocks are slidably mounted in four rectangular slots on a common mounting plate. One end of a spring is welded to the side of the block facing away from the corresponding cooling fan. This simple structure and easy operation enhance cooling efficiency through both water and air cooling. Springs and rubber pads, respectively, reduce vibration during operation of the cooling fan and water pump, thereby reducing noise.

[0004] However, the above-mentioned heat dissipation device for AI servers still has the following problems during actual use: although the AI server is assisted in heat dissipation by a heat dissipation mechanism, such a heat dissipation mechanism is usually installed in a positioning structure, which cannot be compatible with the server, resulting in poor heat dissipation effect. At the same time, the noise of wind-type heat dissipation is too loud, and the exchange of internal and external air during heat dissipation causes dust to be adsorbed, which also affects the heat dissipation effect in long-term operation.

[0005] Therefore, we propose a liquid-cooled AI server to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a liquid-cooled AI server to solve the problem that the existing AI server uses a heat dissipation mechanism to assist the heat dissipation.

At the same time, the wind-type heat dissipation noise is too loud, and the exchange of internal and external air during heat dissipation causes dust to be adsorbed, which also affects the heat dissipation effect after long-term operation.

[0015] Preferably, the dust removal mechanism includes a driving shaft, and the driving shaft is rotatably arranged on the top of the positioning guard plate through a bearing, and the driving shaft is engaged with the outer end of the transmission shaft on the top surface of the heat dissipating slide plate through a second bevel gear group.

[0016] Preferably, the driving shaft and the second bevel gear group included in the dust removal mechanism are rotated and slid by the concave-convex structure of the outer wall, and the driving shaft and the second bevel gear group at the outer end of the transmission shaft are connected to each other through a retaining positioning frame, so that the transmission shaft can maintain engagement and drive with the driving shaft through the second bevel gear group at different positions.

[0017] Compared with the prior art, the present invention has the following beneficial effects: the liquid-cooled AI server, through positioning guard plates symmetrically located on the front and rear sides of the server body, assists the server body in achieving internal and external air exchange.

[0027] like Figure 1-Figure 2 、 Figure 9 As shown, the server body 1 is placed above the supporting base 2, and the positioning guard plate 3 and the heat dissipation slide plate 4 symmetrically arranged on the top surface of the supporting base 2 are located on the outside of the server body 1, thereby providing protection during the operation of the server body 1. At the same time, the winding shaft 8 locked on the front and rear sides of the supporting base 2 is loosened, and the traction steel cable 9 wound on the outer wall is driven to be wound, so that the traction steel cable 9 drives the closed lining plate 7 fixedly connected at the top to slide upward after passing through the positioning guard plate 3, and then the originally blocked ventilation window 5 is opened, so that the heat dissipated by the server body 1 can be discharged outward through the ventilation window 5, and the dust-proof partitions 6 distributed obliquely and equidistantly are used to minimize the entry of external dust, thereby ensuring the working environment of the server body 1.
