Description

Technical Field

[0001] This utility model relates to the field of server rack heat dissipation technology, and in particular to a server rack with good heat dissipation performance. Background Technology

[0002] In data centers, server racks serve as the core carriers for electronic devices such as servers and switches, and their heat dissipation performance directly affects the stability and lifespan of the equipment.

[0003] Traditional server racks often use a single fan group at the top or bottom for heat dissipation. Airflow can easily form turbulence in the middle of the rack, causing heat to accumulate in local areas of densely deployed electronic devices and resulting in hotspots. This is especially true in blade server clusters, where the small spacing between devices hinders heat exchange and can easily lead to device frequency reduction or downtime.

[0004] Therefore, this utility model provides a server rack with good heat dissipation. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a server rack with good heat dissipation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a server rack with good heat dissipation effect, including a rack body and a heat dissipation component. The heat dissipation component includes heat dissipation side plates fixedly connected to both ends of the outer side of the rack body. The heat dissipation side plates have air guide plate receiving grooves inside. An air guide plate rotating shaft is rotatably connected to the air guide plate receiving grooves. An adjustable air guide plate is fixedly connected inside the air guide plate rotating shaft. A lower air guide block is fixedly connected to the bottom outer side of the adjustable air guide plate. An upper air guide block is fixedly connected to the top outer side of the adjustable air guide plate.

[0007] The ventilation assembly includes ventilation partitions fixedly connected to the upper and lower ends of the main body of the cabinet, and a cooling fan is installed inside the ventilation partition.

[0008] In a preferred embodiment, a ventilation baffle is fixedly connected to the outer side of the heat dissipation side plate, and an air guide arc block is provided on the outer side of the ventilation baffle.

[0009] In one preferred embodiment, the outer side of the adjustable air guide plate is rotatably connected to the air guide plate receiving groove, and the lower air guide block and the upper air guide block are symmetrically offset.

[0010] In a preferred embodiment, a top ventilation opening is fixedly connected to the top of the cabinet body.

[0011] In a preferred embodiment, the axis of the air guide plate shaft is arranged parallel to the surface of the heat dissipation side plate.

[0012] In a preferred embodiment, both the lower and upper air guide blocks are triangular convex ridges, and are staggered along the height direction on the same side surface of the adjustable air guide plate.

[0013] In a preferred embodiment, the air guide arc block extends continuously laterally on the outside of the ventilation baffle, and its cross-section is arc-shaped.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. By powering on and rotating the cooling fan, a vertical suction force is created under the constraint of the ventilation baffle. This force draws hot air from inside the cabinet upwards and along the inner side of the cooling side panel to the top ventilation opening. This causes the cooling side panel to diffuse heat outwards. This design achieves the benefits of simultaneous active exhaust and passive cooling of the side panel, which quickly reduces the overall temperature inside the cabinet. It also avoids turbulence in the middle, solves the problem of hot spot accumulation, and improves the uniformity of overall heat dissipation.

[0016] 2. The adjustable air guide plate rotates around the air guide plate shaft through airflow, which in turn drives the lower air guide block and the upper air guide block to rotate synchronously. This guides the external cold air to cut into the outer surface of the heat dissipation side plate at an angle. At the same time, the ventilation baffle blocks the airflow from escaping, and the air guide arc block guides the lateral airflow in an arc. This design achieves the benefits of efficient heat exchange between the external cold air and the heat dissipation side plate, uniform airflow, and reduced wind resistance. It effectively solves the problem of heat exchange obstruction in dense equipment scenarios and avoids equipment frequency reduction or shutdown. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this embodiment provides a technical solution: a server rack with good heat dissipation effect, including a rack body 1 and a heat dissipation component 2. The heat dissipation component 2 includes a heat dissipation side plate 21 fixedly connected to both ends of the outer side of the rack body 1. The heat dissipation side plate 21 has an air guide plate receiving groove 22 inside. An air guide plate rotating shaft 23 is rotatably connected to the air guide plate receiving groove 22. An adjustable air guide plate 24 is fixedly connected inside the air guide plate rotating shaft 23. A lower air guide block 25 is fixedly connected to the bottom outer side of the adjustable air guide plate 24. An upper air guide block 26 is fixedly connected to the top outer side of the adjustable air guide plate 24. The outer side of the adjustable air guide plate 24 is rotatably connected to the air guide plate receiving groove 22. The lower air guide block 25 and the upper air guide block 26 are symmetrically staggered. The axis of the air guide plate rotating shaft 23 is arranged parallel to the surface of the heat dissipation side plate 21. The lower air guide block 25 and the upper air guide block 26 are both triangular protrusions and are staggered along the height direction on the same side surface of the adjustable air guide plate 24.

[0029] At both ends of the outer side of the main cabinet 1, the passive heat dissipation capacity is improved by increasing the outer surface area of ​​the cabinet. On the other hand, it serves as the mounting carrier for the air guide plate receiving slot 22 and the ventilation baffle 33, integrating heat dissipation functional components. The air guide plate receiving slot 22 is opened inside the heat dissipation side plate 21 to accommodate the adjustable air guide plate 24 and provide a limiting space for its rotation, preventing the air guide plate from going out of the preset range due to excessive rotation, and protecting the air guide plate from external collisions. The air guide plate pivot 23 serves as the rotation fulcrum of the adjustable air guide plate 24. Its axis is designed to be parallel to the surface of the heat dissipation side plate 21, allowing the air guide plate to rotate in a direction parallel to the side plate. The adjustable air guide plate 24 rotates around the air guide plate pivot 23, changing the angle between itself and the heat dissipation side plate 21, thereby guiding the airflow outside the cabinet to the surface of the heat dissipation side plate 21, or guiding the heat emitted by the side plate to diffuse in a specific direction. The triangular convex structure of the lower air guide block 25 and the upper air guide block 26 can disturb the airflow passing through the adjustable air guide plate 24, enhancing the heat exchange efficiency between the airflow and the air guide plate and the heat dissipation side plate 21. The staggered arrangement in the height direction can avoid the airflow collision between the upper and lower air guide blocks 25, so that the airflow flows evenly along the surface of the air guide plate, while increasing the contact area between the airflow and the air guide plate.

[0030] like Figure 1 , Figure 4 and Figure 6 As shown, the ventilation component 3 includes ventilation partitions 31 fixedly connected to the upper and lower ends of the main body 1 of the cabinet. A cooling fan 32 is installed inside the ventilation partition 31. A ventilation baffle 33 is fixedly connected to the outer side of the heat dissipation side plate 21. An air guide arc block 34 is opened on the outer side of the ventilation baffle 33. A top ventilation port 35 is fixedly connected to the top of the main body 1 of the cabinet. The air guide arc block 34 extends continuously in the horizontal direction on the outer side of the ventilation baffle 33, and its cross-section is arc-shaped.

[0031] The main cabinet 1 serves as the basic load-bearing structure of the server rack, used to install and fix servers and other equipment. It also provides an installation reference for the heat dissipation components 2 and ventilation components 3, forming a closed or semi-closed equipment housing space. The heat dissipation side panel 21 is fixed to the ventilation partition 31 at both ends of the main cabinet 1. This serves two purposes: firstly, it separates the internal space of the rack; secondly, it acts as a mounting carrier for the cooling fan 32, providing a stable assembly structure for the fan and guiding the airflow driven by the fan along a preset path. The cooling fan 32 is installed inside the ventilation partition 31, accelerating the convection exchange of air inside and outside the rack through active exhaust or ventilation, quickly dissipating the heat generated by the internal equipment. Simultaneously, it drives the airflow through the heat dissipation side panel 21, enhancing its passive cooling effect. For heat dissipation, the ventilation baffle 33 is fixed to the outside of the heat dissipation side plate 21. On the one hand, it blocks external debris from entering the airflow channel near the heat dissipation side plate 21 and protects the heat dissipation components. On the other hand, it guides the airflow along the surface of the heat dissipation side plate 21 and prevents the airflow from spreading to the direction where there is no heat dissipation requirement. The arc-shaped cross-section of the air guide block 34 can reduce the wind resistance when the airflow passes through the ventilation baffle 33. The horizontal continuous extension design can guide the airflow to be evenly distributed along the horizontal side plate 21, ensuring that each area of ​​the side plate can fully contact the airflow. The top ventilation port 35 works with the ventilation baffle 31 and the cooling fan 32 at the top of the cabinet to serve as the main outlet for the upper hot airflow, quickly expelling the hot air drawn out by the fan from the top of the cabinet and preventing heat from accumulating in the upper part of the cabinet.

[0032] Working principle:

[0033] like Figure 1 - Figure 6 As shown:

[0034] In use: First, the cooling fan 32 is powered on and rotates, forming a vertical suction force under the limitation of the ventilation baffle 31. This then drives the hot air inside the cabinet body 1 to concentrate upwards, which in turn drives the hot airflow to flow quickly along the inner surface of the heat dissipation side plate 21 to the top ventilation port 35. This causes the temperature of the heat dissipation side plate 21 to rise and dissipate the heat outwards, achieving initial cooling by simultaneously starting active exhaust and passive heat dissipation of the side plate. First, the adjustable air guide plate 24 is automatically moved, rotating at a certain angle around the air guide plate pivot 23 within the air guide plate receiving groove 22, which in turn drives its surface... The lower air guide block 25 and the upper air guide block 26 rotate synchronously, which can drive the external cold air to cut into the outer surface of the heat dissipation side plate 21 at a set angle. This causes the airflow to form multiple disturbances and wall adhesion effects between the staggered triangular protrusions. The ventilation baffle 33 blocks the airflow from escaping. The horizontally continuous air guide arc block 34 on its outer side guides the lateral airflow in an arc, which in turn drives the airflow to spread evenly along the heat dissipation side plate 21 in the horizontal direction. This can avoid local overheating and reduce the temperature gradient of the entire side plate, achieving a three-fold optimized heat dissipation effect of uniform temperature on the side plate surface and reduced noise.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
