Description

Technical Field

[0001] The present invention belongs to the technical field of cooling devices, and particularly relates to a double-slot GPU air-increasing cooling device and method. Background Art

[0002] With the rapid development of computer technology, especially the growth of high-performance computing and graphics processing requirements, parallel operation of multiple graphics cards has become a common configuration. This configuration is particularly important in fields such as deep learning, big data analysis, and high-end gaming. However, a major challenge in such multi-GPU systems lies in the heat dissipation problem. Especially when multiple graphics cards are installed side by side, how to ensure sufficient air intake space to maintain efficient cooling has become a key technical problem. Traditional cooling solutions usually rely on increasing the number of fans or improving the radiator design, but these methods often struggle to effectively solve the problem of poor air circulation caused by the close distance between graphics cards. Therefore, in the face of high-density graphics card systems, existing cooling technologies have obvious deficiencies in improving air flow efficiency.

[0003] When multiple graphics cards are used side by side, due to physical space limitations, the gap between the graphics cards is very limited, which greatly restricts the inflow path of cold air and the exhaust path of hot air, resulting in low cooling efficiency. Especially in high-performance application scenarios, the graphics cards need to process a large amount of data and generate a huge amount of heat. If the heat cannot be dissipated in a timely and effective manner, it will seriously affect the performance of the graphics cards and may cause hardware damage. In addition, the existing cooling devices also have weak direct cooling capabilities for components such as video memory, further exacerbating the risk of local overheating. Therefore, in view of the special requirements of using multiple graphics cards side by side, it is particularly necessary to develop a new type of cooling device that can significantly improve the utilization rate of air intake space and enhance the overall heat dissipation effect.

[0004] The design of traditional cooling systems fails to fully consider the air circulation obstacles brought about by the close arrangement of graphics cards. As a result, even if additional fans are added or more efficient heat dissipation materials are used, the ventilation condition between the graphics cards cannot be fundamentally improved. Specifically, the narrow gap between the graphics cards not only restricts the effective entry of cold air but also hinders the rapid exhaust of hot air, forming a so-called "heat island effect", causing the temperature in certain areas to rise abnormally, and further affecting the stability and reliability of the entire system. In addition, the existing technology has imperfect targeted heat dissipation measures for video memory and other heat-generating components, further increasing the risk of local overheating. Therefore, we propose a double-slot GPU air-increasing cooling device and method. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a double-slot GPU air-increasing and cooling device and method. By optimizing the air intake structure, expanding the air intake area, and adopting an efficient heat pipe module, the problem of insufficient air intake space when multiple graphics cards are used side by side is successfully solved, achieving a more uniform and efficient heat dissipation effect, and ensuring the long-term stable operation of the graphics card and other key components.

A second aluminum plate is welded to the lower part of the lower fin radiator. A video memory contact copper block is connected to the lower part of the second aluminum plate.

[0007] Optionally, a backplane module is connected to the lower part of the main board, and a heat pipe back buckle is connected to the backplane module.

[0008] Optionally, second inclined plates are provided on both the left and right sides of the half-height plate, and a triangular connecting plate is connected between the second inclined plates and the first inclined plate.

[0009] Optionally, a plurality of ventilation strips are opened on the second inclined plate, and the width of the ventilation strips is 0.1-2 mm.

[0010] Optionally, an air intake groove is opened on the second fin radiator, and two first inclined surfaces are provided on the air intake groove.

[0011] Optionally, a transition section is provided between the first aluminum plate and the second fin radiator, and the transition section includes a first inclined edge, a second inclined edge, and an arc edge.

[0012] Optionally, the included angle β between the first inclined edge and the vertical direction is set to 113-120°, and the included angle α between the second inclined edge and the vertical direction is set to 43-50°.

[0013] Optionally, a third aluminum plate is fixedly connected to the upper part of the upper fin radiator, and the included angle γ between the second fin radiator and the vertical direction is set to 63-68°.

[0014] Optionally, a MOS transistor, an inductor, and a video memory are installed on the main board. A MOS thermal pad is covered on the MOS transistor, thermal grease is provided on the GPU chip, a video memory thermal pad is provided on the video memory, and an inductor thermal pad is provided on the inductor. The fan is connected to the base through fan screws, the base is connected to the upper air inlet cover through base connection screws, the main board is connected to the base through main board screws, and the backplane module is connected to the main board through backplane screws.

[0015] The present invention also provides a method for increasing air flow and cooling a dual-slot GPU, including the dual-slot GPU air flow increasing and cooling device, and comprising the following steps:

[0016] S1. Prepare two plates with different widths, respectively bend them to make bending parts, which are respectively used to manufacture the first cover plate and the half-height plate, so that the heights of the first cover plate and the half-height plate are different;

[0017] S2. Connect the first cover plate and the half-height plate together with a first inclined plate, and process an upper air inlet on the half-height plate to complete the manufacture of the upper air inlet cover;

[0018] S3. Machine the second fin radiator so that the height of the end close to the lower fin radiator is greater than the end far from the lower fin radiator, and connect the lower fin radiator to the heat pipe module;

[0019] S4. Install the processed upper air inlet cover, heat pipe module, fan, and second fin radiator above the base and assemble them.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The design introduces the bending part between the half-height plate and the first cover plate, and the upper air inlet on the half-height plate. These designs work together to greatly expand the air inlet area of the device. This improvement allows more cold air to flow into the system simultaneously, providing sufficient cooling resources for each heat-generating component. Even when multiple graphics cards are working in parallel, it can ensure sufficient cold air supply, prevent overheating caused by heat accumulation, and extend the service life of the hardware.

[0022] 2. By designing the first inclined plate and the second inclined plate and setting side air inlets and ventilation strips on these plates, the optimization of the air flow path is achieved. This design not only increases the angle and area of air entering the system but also improves the cooling efficiency by guiding the air flow to directly act on the heat source area. While increasing the air intake volume, the air flow resistance is reduced, ensuring that the cold air can efficiently reach the surface of the heating elements, thereby effectively reducing the temperature. The effect of significantly improving the overall heat dissipation performance of the system ensures the stable operation of the graphics card and other key components under high load.

[0023] 3. The vapor chamber module includes components such as a lower fin radiator, a second fin radiator, and a first aluminum plate, forming a complex heat conduction network. Especially the design of the height change of the second fin radiator and the special geometric shape of the transition section further enhance the heat conduction efficiency. Such a configuration can not only quickly absorb the heat from the GPU chip and other heating elements but also quickly dissipate it, maintaining the temperature balance of the system. Therefore, it effectively reduces the possibility of hot spot formation and improves the thermal stability of the entire system, which is crucial for improving computing performance and reliability.

[0048] S4. Install the processed air inlet upper cover 1, heat pipe module 2, fan 3 and second fin heat sink 22 above the base 4 and assemble them.
