Description

Technical Field

[0001] This utility model relates to the field of heat dissipation structure, specifically a direct-contact heat pipe heat dissipation structure for servers. Background Technology

[0002] Against the backdrop of digital transformation and the explosive growth in computing power demand, servers have become the core infrastructure supporting fields such as cloud computing, artificial intelligence, and high-performance computing (HPC). With the rapid development of data centers and artificial intelligence technologies, high-power servers have become the core infrastructure supporting computing-intensive applications. These servers have achieved a leapfrog improvement in single-rack power density through hardware architecture innovation and energy efficiency optimization. Servers need to dissipate heat when they are working, and heat dissipation requires the use of heat dissipation structures.

[0003] Existing server cooling structures have poor heat dissipation performance during operation, as they only come into contact with the heat source inside the server and mainly dissipate heat naturally through their external heat dissipation fins, resulting in low heat dissipation efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a direct-contact heat pipe heat dissipation structure for servers to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a direct-contact heat pipe heat dissipation structure for servers, comprising a heat dissipation body, a plurality of heat dissipation fins fixed to the top of the heat dissipation body, a plurality of first heat dissipation pipes disposed inside the heat dissipation body, and a remote heat dissipation component installed at the end of each first heat dissipation pipe, the number of the remote heat dissipation components being three, the end of each first heat dissipation pipe being located between the three remote heat dissipation components, a plurality of second heat dissipation pipes disposed inside the heat dissipation body, the second heat dissipation pipes being C-shaped, and a capillary structure disposed inside the first and second heat dissipation pipes, the capillary structure being a mixture of copper powder and binder, fixed inside the first and second heat dissipation pipes by a high-temperature sintering process to form a porous network.

[0006] By adopting the above technical solution, multiple sets of heat dissipation fins are close to each other, and the spacing between each set of heat dissipation fins is small, increasing the surface area for heat dissipation. This allows heat to come into more full contact with the air and dissipate to the surrounding environment through thermal convection and thermal radiation. The heat dissipation fins are made of aluminum, which has the characteristics of good thermal conductivity, light weight and low cost. The heat-fused buckles can easily fix the heat dissipation body to the inside of the server chassis, avoiding the problem of the server separating from the heat dissipation body due to vibration during operation, ensuring that the relative positions of each component remain stable, so that the heat dissipation system can work normally.

[0007] The present invention is further provided with heat-fused buckles on both sides of the heat dissipation body.

[0008] Preferably, the heat sink can be easily fixed to the inside of the server chassis by means of a heat sink buckle, which can prevent the server from separating from the heat sink due to vibration during operation.

[0009] The present invention is further configured such that a heat-conducting component is fixed at the bottom of the heat dissipation body, and the material of the heat-conducting component is thermal grease.

[0010] Preferably, the heat dissipation effect of the heat dissipation body can be improved by setting the heat conduction components.

[0011] The present invention is further provided that a label is provided on the top of the heat dissipation fins.

[0012] Preferably, the labels can remind the user of the order in which the bolts are tightened.

[0013] The present invention is further configured such that both ends of the first heat sink and one end of the second heat sink are both flat.

[0014] Preferably, the flat-shaped first and second heat dissipation pipes can increase the contact area between the heat dissipation body and the remote heat dissipation component, thereby facilitating heat dissipation.

[0015] In summary, the present invention has the following main advantages:

[0016] This utility model incorporates a first heat dissipation pipe, a second heat dissipation pipe, a heat dissipation body, and a remote heat dissipation component. Multiple sets of heat dissipation fins are positioned close to each other, with small spacing between each set of fins, increasing the surface area for heat dissipation. This allows heat to come into more full contact with the air, dissipating it into the surrounding environment through thermal convection and radiation. The heat dissipation fins are made of aluminum, which has good thermal conductivity, is lightweight, and has low cost. The heat-fused fasteners facilitate the fixation of the heat dissipation body to the inside of the server chassis, preventing the server from separating from the heat dissipation body due to vibration during operation. This ensures that all components maintain a stable relative position, allowing the heat dissipation system to function properly. Attached Figure Description
