Description

Technical Field

[0001] The utility model belongs to the technical field of servers, and in particular relates to an intelligent network card air guide cover and a server module for heat dissipation of a server. Background Art

[0002] With the booming development of the big data industry, server performance continues to improve, and the integration of internal server components is also increasing. As a result, these components tend to generate a lot of heat during operation. Given the high sensitivity of internal server components to temperature changes, achieving efficient heat dissipation within the limited server space has become a core challenge that needs to be addressed and solved.

[0003] Currently, the cooling methods commonly used in existing servers are mainly divided into water cooling and air cooling. Water cooling generally involves placing a cold plate inside the server. A layer of thermally conductive adhesive ensures good contact between the component to be cooled and the cold plate. This layer of thermally conductive adhesive transfers heat from the component to the cold plate, achieving a cooling effect. However, in practice, this cooling method often requires a large space inside the server to install the cold plate, making it unsuitable for cooling smart network cards within the server.

[0004] Air-cooled heat sinks typically use fan modules installed inside or outside the server, using the airflow from the fan to remove heat from the components being cooled, thereby achieving a cooling effect. Therefore, compared to water-cooled heat sinks, air-cooled heat sinks do not require as much space inside the server, making them more suitable for cooling Smart NICs within the server. However, due to the current layout of internal server components, the location of Smart NICs often has limited air intake area, which prevents them from maximizing air cooling efficiency and makes them prone to overheating. Utility Model Content

[0005] The purpose of this utility model is to address the problem that the smart network card in the existing server is prone to overheating during use, and to propose and design a smart network card air guide cover and server module for server heat dissipation, so as to effectively improve the air cooling and heat dissipation efficiency of the smart network card, thereby ensuring the stability and service life of the server and the smart network card.

[0006] In order to achieve the above-mentioned purpose, on the one hand, the utility model provides an intelligent network card air guide cover for server heat dissipation, which includes an air guide plate, and the air guide plate is arranged in sequence along its own length direction as a snap-on part one, a network card facing part, an inclined guide part, and a snap-on part two, and the inclined guide part is inclined in the direction away from the network card facing part. In this way, when the utility model is installed on one side of the intelligent network card, it can set a trumpet structure at the air inlet end of the intelligent network card through the inclined guide part of the intelligent network card air guide cover for server heat dissipation, and set a wind shield structure on the side of the intelligent network card through the network card facing part of the intelligent network card air guide cover for server heat dissipation, thereby effectively increasing the air inlet area of ​​the intelligent network card and reducing side wind leakage, realizing heat dissipation optimization, solving the early overheating problem, and achieving the ultimate goal of improving the stability and service life of the server and the intelligent network card.

[0007] Furthermore, the first clamping portion is the end of the air guide plate, and can be directly inserted into the gap between the smart network card and the adjacent component or into the slot at the front end of the smart network card in the server shell to fix the air guide plate at the front end of the smart network card.

[0008] Furthermore, the second clamping portion includes a bent vertical edge disposed at the end of the air deflector. The upper end of the bent vertical edge is bent to form a horizontal surface (1). The edge of the horizontal surface (1) is bent downward to form at least one vertical surface (1). A fixing hole is formed in the middle of the at least one vertical surface (1). A locking member is threadedly connected to the fixing hole. The slot structure formed by the horizontal surface (1) and the vertical surface (1) can be clamped onto the rear power board inside the server. The locking member is tightened against the side of the rear power board inside the server to secure the air deflector to the power board located at the rear end of the smart network card. The locking member is preferably an elastic bolt, which not only reduces the impact of temperature on the bolt strength but is also suitable for locations that withstand large alternating loads and vibration.

[0009] Furthermore, a third clamping portion is provided at the upper end of the network card facing portion, and the network card facing portion of the air guide plate and the smart network card can be clamped together through the third clamping portion to achieve fixation between the air guide plate and the smart network card.

[0010] Furthermore, the clamping portion three includes a horizontal surface two arranged at the upper end of the air guide plate, the edge of the horizontal surface two is bent downward to form a vertical surface two, and the L-shaped clamping plate structure formed by the horizontal surface two and the vertical surface two can be clamped on the upper end of the smart network card to achieve the fixation of the air guide plate at the upper end of the smart network card.

[0011] Furthermore, the surface of the air deflector is wrapped with a Mylar sheet, and the Mylar sheet prevents components such as the smart network card from being scratched during the installation of the air deflector.

[0012] Furthermore, the air guide plate is an integrally bent part.

[0013] Furthermore, the air guide plate includes a first air guide support plate and a second air guide support plate. The first air guide support plate is a flat plate, and the first clamping portion and the network card facing portion are arranged on the first air guide support plate. The second air guide support plate is an obtuse-angled bent plate, and the end of the first air guide support plate is detachably connected to one side of the second air guide support plate, and the inclined guide portion and the second clamping portion are arranged on the other side of the second air guide support plate. In this way, since the air guide plate of the utility model adopts an assembled structure, it not only ensures that the entire structure can be better implemented, but also facilitates the production of the entire air guide plate in the factory.

[0014] On the other hand, the present invention also provides a server module, which includes a server body, a smart network card installed in the server body, an air duct provided at one end of the smart network card, and the above-mentioned smart network card air guide cover for server heat dissipation installed on one side of the smart network card, the network card facing portion of the smart network card air guide cover for server heat dissipation is arranged opposite to the side of the smart network card, and the inclined guide portion of the smart network card air guide cover for server heat dissipation is arranged opposite to the air duct and guides the airflow at the air duct. In this way, since the present invention provides a trumpet structure at the air inlet end of the smart network card through the inclined guide portion of the smart network card air guide cover for server heat dissipation, and provides a wind shield structure on the side of the smart network card through the network card facing portion of the smart network card air guide cover for server heat dissipation, it can effectively increase the air inlet area of ​​the smart network card and reduce side wind leakage, thereby achieving heat dissipation optimization and solving the early overheating problem, thereby achieving the ultimate goal of improving the stability and service life of the server and the smart network card.

[0015] Furthermore, a power board and a processing board are installed in the server body, and the air duct and the smart network card are arranged between the power board and the processing board in sequence in the direction away from the power board. One end of the smart network card air guide cover for server heat dissipation is connected to the power board through the second clamping part, and the other end of the smart network card air guide cover for server heat dissipation is inserted between the smart network card and the adjacent components of the smart network card through the first clamping part to achieve the fixation of the smart network card air guide cover for server heat dissipation in the server body.

[0016] It can be seen from the above technical solutions that the present invention has the following advantages:

[0017] 1. When the present invention is installed on one side of a smart network card, a bell-mouth structure can be provided at the air inlet end of the smart network card through the inclined guide portion of the smart network card air guide cover for server heat dissipation, thereby effectively increasing the air inlet area of ​​the smart network card and achieving heat dissipation optimization;

[0018] 2. When the present invention is installed on one side of a smart network card, a wind shield can be provided on the side of the smart network card through the network card facing portion of the smart network card air guide cover for server heat dissipation, thereby effectively preventing the problem of wind leakage from the side of the smart network card and further optimizing the heat dissipation effect.

[0019] 3. Each clamping structure in the present invention not only enables the intelligent network card air guide cover for server heat dissipation to be fixed within the server body, but also has the characteristics of simple operation and convenient processing;

[0020] 4. Since the surface of the air guide plate is wrapped with Mylar sheets in the present invention, the Mylar sheets can also prevent components such as smart network cards from being scratched during the installation of the air guide plate. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1 、 Figure 2As shown, this first embodiment provides a first smart network card air guide cover for server heat dissipation, comprising an air guide plate, the air guide plate comprising an air guide support plate 1 and an air guide support plate 2 5, arranged sequentially along the length of the air guide plate. The air guide support plate 1 is a flat plate, and a snap-on portion 14 and a network card facing portion 13 are sequentially arranged along the upper edge of the air guide support plate 1 in a direction approaching the air guide support plate 2 5. Specifically, in this first embodiment, the snap-on portion 14 is the end of the air guide support plate 1 away from the air guide support plate 2 5, i.e., the end of the air guide plate. The snap-on portion 14 can be directly inserted into the gap between the smart network card and adjacent components, or into a slot located at the front end of the smart network card within the server housing, to secure the air guide plate at the front end of the smart network card.

[0028] The network card facing portion 13 is the position on the air guide support plate 1 that faces the smart network card. When the air guide support plate 1 is installed on the smart network card, the network card facing portion 13 is arranged parallel to the smart network card. The surface of the network card facing portion 13 is provided with a avoidance groove 4 for avoiding the upper structure of the smart network card. The upper end of the network card facing portion 13 is provided with a clamping portion 3 12 for securing the air guide support plate 1 to the smart network card. The clamping portion 3 12 includes a horizontal surface 2 2 provided on the upper end of the air guide support plate 1. The edge of the horizontal surface 2 2 away from the network card facing portion 13 is bent downward to form a vertical surface 2 3. In this way, the L-shaped clamping plate structure formed by the horizontal surface 2 2 and the vertical surface 2 3 can be clamped to the upper end of the smart network card to secure the air guide support plate 1 to the upper end of the smart network card.

[0029] The second air guide support plate 5 is a blunt-angled bent plate, and one side of the second air guide support plate 5 is detachably connected to the end of the first air guide support plate 1 via bolts or other fasteners. The other side of the second air guide support plate 5 is sequentially provided with an inclined air guide portion 6 and a second clamping portion 11, in a direction away from the first air guide support plate 1. Specifically, in this first embodiment, the inclined air guide portion 6 is the side of the second air guide support plate 5 not connected to the first air guide support plate 1, and is inclined away from the network card facing portion 13. The surface of the inclined air guide portion 6 and the other side of the second air guide support plate 5 are both provided with a clearance groove 4 for accommodating components associated with the smart network card.

[0030] The second clamping portion 11 includes a bent vertical edge 10 disposed on the second air guide support plate 5 at one end away from the first guide support plate. The upper end of the bent vertical edge 10 is bent to form a horizontal surface 7. At least one of the four edges of the horizontal surface 7 is bent downward to form a vertical surface 9. A fixing hole is penetrated in the middle of at least one of the vertical surfaces 9, and a locking member 8 is threadedly connected to the fixing hole. In this way, the slot structure formed by the horizontal surface 7 and the vertical surface 9 can be clamped on the rear power board inside the server. The locking member 8 is tightened and abutted against the side of the rear power board inside the server to secure the air guide plate to the power board located at the rear end of the smart network card. The locking member 8 is preferably an elastic bolt, which not only reduces the impact of temperature on the bolt strength, but is also suitable for areas that withstand large alternating loads and high vibration.

[0031] In this way, when the first embodiment of the present invention is installed on one side of the smart network card, a trumpet structure can be set at the air inlet end of the smart network card through the inclined guide portion 6 of the smart network card air guide cover for server heat dissipation, and a wind shield structure can be set on the side of the smart network card through the network card facing portion 13 of the smart network card air guide cover for server heat dissipation, thereby effectively increasing the air inlet area of ​​the smart network card and reducing side wind leakage, realizing heat dissipation optimization, solving the early overheating problem, and achieving the ultimate goal of improving the stability and service life of the server and the smart network card.

[0032] Moreover, as a preference, the first embodiment of the present invention can also wrap the surface of the air guide support plate 1 and the air guide support plate 2 5 with Mylar sheets, and use the Mylar sheets to prevent components such as the smart network card from being scratched during the installation process of the entire air guide plate.

[0033] Example 2

[0034] The second embodiment provides a second intelligent network card air guide cover for server heat dissipation. Compared with the first embodiment, the difference of the second embodiment is that the air guide plate in the second embodiment is an integral bent part, that is, the air guide plate in the second embodiment is directly processed and formed as a whole, and is not divided into two parts: the air guide support plate 1 and the air guide support plate 5.

[0035] Specifically, in the second embodiment, the air deflector is sequentially arranged along its length to include a first clamping portion 14, a network card facing portion 13, an inclined air guide portion 6, and a second clamping portion 11. The first clamping portion 14 is one end portion of the first air deflector and can be directly inserted into the gap between the smart network card and adjacent components, or into a slot in the server housing at the front end of the smart network card, thereby securing the air deflector at the front end of the smart network card.

[0036] The network card facing portion 13 is the portion of the air guide plate that faces the smart network card. When the air guide support plate 1 is installed on the smart network card, the network card facing portion 13 is arranged parallel to the smart network card. The surface of the network card facing portion 13 is provided with a clearance groove 4 for avoiding the upper structure of the smart network card. The upper end of the network card facing portion 13 is provided with a clamping portion 3 12 for securing the air guide plate to the smart network card. The clamping portion 3 12 includes a horizontal surface 2 2 disposed at the upper end of the air guide plate. The edge of the horizontal surface 2 2 is bent downward to form a vertical surface 3 2. This allows the L-shaped clamping plate structure formed by the horizontal surface 2 2 and the vertical surface 2 3 to be clamped to the upper end of the smart network card to secure the air guide plate to the upper end of the smart network card.

[0037] The inclined guide portion 6 is a position on the air guide plate used to face the air duct provided at the rear end of the smart network card, and the inclined guide portion 6 is inclined in a direction away from the network card facing portion 13. The surface of the inclined guide portion 6 is also provided with an avoidance groove 4 for avoiding relevant components at the smart network card.

[0038] The second clamping portion 11 includes a bent vertical edge 10 positioned at the other end of the air deflector. The upper end of the bent vertical edge 10 is bent to form a horizontal surface 7. At least one of the four edges of the horizontal surface 7 is bent downward to form a vertical surface 9. At least one of the vertical surfaces 9 has a fixing hole extending through the center thereof, and a locking member 8 is threadedly connected to the fixing hole. This allows the slot structure formed by the horizontal surface 7 and the vertical surface 9 to be clamped onto the rear power board within the server. The locking member 8 is then tightened against the side of the rear power board within the server to secure the air deflector to the power board located at the rear of the smart network card. Furthermore, the locking member 8 is preferably an elastic bolt, which not only reduces the effect of temperature on the bolt strength but is also suitable for locations subject to large alternating loads and high vibration.
