Abstract
Description
Technical Field
[0001] This utility model relates to the field of server rack technology, specifically to a heat dissipation mechanism for a computer server rack. Background Technology
[0002] In the digital age, computer servers, as the core carriers of data storage, processing, and transmission, directly determine the service quality of various information systems through their operational stability. Server racks, as the installation and protection equipment for server clusters, not only need to provide physical support and security, but also need to address the issue of the large amount of heat generated during server operation. Under high load conditions (such as massive parallel computing in data centers and continuous operation of enterprise applications), core components such as the CPU, hard drive, and power supply continuously release heat. If this heat cannot be dissipated in time, the temperature inside the rack will rise sharply.
[0003] In current technologies, server rack cooling primarily employs a combination of passive and simple active cooling. Passive cooling typically relies on ventilation holes or grilles on the rack's side walls, utilizing natural air convection for heat exchange. However, this method is highly susceptible to ambient airflow, resulting in extremely low cooling efficiency in enclosed server rooms or densely packed server configurations. This can easily create a "heat island effect," preventing heat from dissipating upwards from lower-level servers and causing localized overheating. Simple active cooling often involves installing axial fans at a single location on the top or bottom of the rack, forcing airflow to circulate within the rack. However, due to the lack of directional airflow guidance structures, cool air cannot accurately target heat-generating components, leading to chaotic exhaust paths and often creating "heat dissipation blind spots." For multi-level server installations, the cooling performance differs significantly between upper and lower levels.
[0004] To address the aforementioned issues, there is an urgent need for a server rack cooling system that features "directional airflow guidance and multi-layer balanced heat dissipation" to overcome the shortcomings of traditional cooling methods, such as low efficiency and insufficient reliability, and to ensure the stable operation of servers under various operating conditions. Utility Model Content
[0005] To address the problems mentioned in the background section, the present invention aims to provide a heat dissipation mechanism for a computer server rack, which has the advantage of good heat dissipation performance.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation mechanism for a computer server rack, comprising a server rack body, wherein multiple partitions evenly distributed vertically are fixedly connected inside the server rack body, multiple evenly distributed ventilation holes are provided on the top of the partitions, a fan shroud is fixedly connected to the bottom of the partitions, the ventilation holes communicate with the fan shroud, air inlet pipes are connected to both sides of the back of the fan shroud, the back of the air inlet pipes extends to the back of the server rack body, a fan is fixedly connected inside the air inlet pipes by a bracket, an opening is provided on the top of the server rack body, a top plate is fixedly connected to the top of the server rack body by a bracket, a dustproof mesh frame is fixedly connected to the top of the server rack body, and the top of the dustproof mesh frame is fixedly connected to the bottom of the top plate.
[0007] As a preferred embodiment of this utility model, ventilation openings are provided on both sides of the top of the partition. Through the setting of the ventilation openings, the air below the partition can easily move upward from the ventilation openings and finally be discharged to the outside of the device through the dustproof mesh frame.
[0008] As a preferred embodiment of this utility model, multiple evenly distributed heat-conducting strips are provided on both sides of the server cabinet, and the side of the heat-conducting strips on the left and right sides that are close to each other extends into the interior of the server cabinet, while the side of the heat-conducting strips on the left and right sides that are far apart from each other extends into the exterior of the server cabinet.
[0009] As a preferred embodiment of this utility model, air blowers are fixedly connected to the top of both sides of the server cabinet. The output end of the air blower is set downwards, and an air inlet is set on the back of the air blower. The air blower can accelerate the air circulation rate on the surface of the heat conduction strip located on the outside of the server cabinet, thereby dissipating heat from the heat conduction strip. The air blower is connected to the air outlet of the external air pump through a pipe.
[0010] As a preferred embodiment of this invention, a dust-blocking mesh is fixedly connected to the back of the air intake pipe.
[0011] As a preferred embodiment of this utility model, a cabinet door is hinged to the left side of the front of the server cabinet, and an observation window is provided on the front of the cabinet door.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model adopts a combined design of server cabinet, partitions, ventilation holes, fan shrouds, air intake pipes, fans, top plates, and dustproof mesh frames. Its core beneficial effect lies in constructing a highly efficient and directional heat dissipation airflow channel. When the fan is running, low-temperature air is introduced from outside the cabinet through the air intake pipes. After being gathered by the fan shroud, it is precisely blown onto the server equipment on the partitions through the ventilation holes, directly carrying away the heat generated by the equipment operation. The heated air rises, enters the dustproof mesh frame through the opening at the top of the cabinet, and then exits the cabinet. This bottom-in, top-out airflow circulation mode, combined with evenly distributed partitions and ventilation holes, allows each layer of equipment to enjoy stable heat dissipation. At the same time, the dustproof mesh frame can intercept impurities in the air, preventing dust accumulation from affecting equipment performance and heat dissipation efficiency, and extending the service life of the equipment. This device has the advantage of excellent heat dissipation effect.
[0014] 2. This utility model further optimizes the airflow circulation efficiency inside the cabinet by setting up ventilation openings. When the fan drives cold air to act on the bottom of the equipment, some hot air will diffuse to the area below the upper partition. The ventilation openings provide a convenient upward channel for this part of hot air, allowing it to quickly merge with the hot airflow at the top of the cabinet and be discharged together through the dustproof mesh frame. This design makes the airflow inside the cabinet smoother, avoids the accumulation of hot air under the partition that causes local temperature rise, effectively improves the synergy of the overall heat dissipation system, and ensures that the equipment continues to operate at a suitable temperature.

[0020] 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.
[0021] like Figures 1 to 4 As shown, a heat dissipation mechanism for a computer server rack includes a server rack 1. Multiple vertically evenly distributed partitions 2 are fixedly connected inside the server rack 1. Multiple evenly distributed ventilation holes 3 are opened on the top of the partitions 2. A fan shroud 4 is fixedly connected to the bottom of the partitions 2, and the ventilation holes 3 communicate with the fan shroud 4. Air intake pipes 5 are connected to both sides of the back of the fan shroud 4, extending to the back of the server rack 1. A fan 6 is fixedly connected inside the air intake pipe 5 via a bracket. An opening is opened at the top of the server rack 1. A top plate 7 is fixedly connected to the top of the server rack 1 via a bracket. A dustproof mesh frame 8 is fixedly connected to the top of the server rack 1, with the top of the dustproof mesh frame 8 fixedly connected to the bottom of the top plate 7. Mounting brackets 14 for installing servers or other computer network equipment are fixedly connected to both sides of the top of the partitions 2. Mounting brackets 14 have mounting openings 15 on their tops. Servers or other computer network equipment are mounted using screws. When mounted on the mounting bracket 14, there is a gap between the bottom of the server or other computer network equipment and the partition 2. The back of the server cabinet 1 is provided with a cable passage port, and a sealing ring is provided inside the cable passage port to improve the sealing between the cable and the cable passage port and to prevent the cable from being cut by the cable passage port. The server cabinet 1 is a common existing technology and is common knowledge to those skilled in the art. This application will not describe it in detail. The standard parts used in this utility model can all be purchased from the market. The irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. It will not be described in detail here. The contents not described in detail in this specification are common prior art known to those skilled in the art. This application will not describe them in detail.
[0022] refer to Figure 3 Ventilation openings 9 are provided on both sides of the top of the partition 2. Through the setting of the ventilation openings 9, the air below the partition 2 can easily move upward from the ventilation openings 9 and finally be discharged to the outside of the device through the dustproof mesh frame 8.
[0023] As a technical optimization of this utility model, the airflow circulation efficiency inside the cabinet is further optimized by setting the ventilation port 9. When the fan 6 drives the cold air to act on the bottom of the equipment, some hot air will diffuse to the area below the upper partition 2. The ventilation port 9 provides a convenient upward channel for this part of the hot air, so that it can quickly merge with the hot airflow in the upper part of the cabinet and be discharged together through the dustproof mesh frame 8. This design makes the air circulation inside the cabinet smoother, avoids the local temperature rise caused by the accumulation of hot air below the partition 2, effectively improves the synergy of the overall heat dissipation system, and ensures that the equipment can continue to operate at a suitable temperature.
[0024] refer to Figure 2 Multiple evenly distributed heat-conducting strips 10 are provided on both sides of the server cabinet 1. The side of the heat-conducting strips 10 that are close to each other extends into the interior of the server cabinet 1, while the side of the heat-conducting strips 10 that are far apart from each other extends into the exterior of the server cabinet 1.
[0025] As a technical optimization of this utility model, the heat-conducting strip 10 is designed to assist in heat dissipation, compensating for the shortcomings of airflow heat dissipation in dense heat transfer. One end of the strip penetrates into the cabinet to contact the high-temperature air, while the other end extends to the outside of the cabinet to contact the low-temperature air. The heat accumulated inside the cabinet is quickly dissipated using the thermal conductivity of the metal. This structure is equivalent to adding additional heat dissipation carriers on both sides of the cabinet. When airflow heat dissipation inside the cabinet is insufficient to quickly remove a large amount of heat, the heat-conducting strip 10 can continuously transfer heat through thermal conduction, expanding the heat dissipation area. Especially when the server is operating under high load and generating a large amount of heat, the heat-conducting strip 10 can effectively share the heat dissipation pressure, prevent a sudden rise in cabinet temperature, provide a strong supplement to airflow heat dissipation, and improve overall heat dissipation redundancy.
[0026] refer to Figure 1 The top of both sides of the server cabinet 1 is fixedly connected to a blower 11. The output end of the blower 11 is set downwards, and the back of the blower 11 is provided with an air inlet. The blower 11 can accelerate the air circulation rate on the surface of the heat conduction strip 10 located on the outside of the server cabinet 1, thereby dissipating heat from the heat conduction strip 10. The blower 11 is connected to the air outlet of the external air pump through a pipe.
[0027] As a technical optimization of this utility model, the configuration of the air blower 11 precisely enhances the heat dissipation efficiency of the heat-conducting strip 10, forming a dual heat dissipation mechanism of "conduction + forced air cooling". The air blower 11, with its output end facing downwards, blows air onto the outer end of the heat-conducting strip 10, significantly accelerating the airflow speed on the surface of the heat-conducting strip 10, quickly carrying away the heat it conducts, preventing heat accumulation on the heat-conducting strip 10 due to slow external airflow, ensuring that the heat-conducting strip 10 always maintains a temperature difference between its inside and outside, and guaranteeing heat conduction efficiency. When used in conjunction with an external air pump, the airflow speed and volume of the air blower 11 can be adjusted according to actual heat dissipation needs, reducing energy consumption under low load and increasing heat dissipation intensity under high load. This dynamically adaptable heat dissipation method makes the heat dissipation capacity of the heat-conducting strip 10 more flexible and efficient, further improving the adaptability and reliability of the entire heat dissipation system.
[0028] refer to Figure 3 A dust filter is fixedly connected to the back of the air intake pipe 5, which is not shown.
[0029] As a technical optimization of this utility model, the dust filter, constructed by the air intake pipe 5 and the internal fan 6, forms the first dust barrier, effectively improving the stability and ease of maintenance of the heat dissipation system. Before outside air enters the air intake pipe 5, the dust filter intercepts dust, lint, and other impurities, preventing them from adhering to the fan blades and affecting the fan speed and airflow efficiency. It also prevents impurities from entering the cabinet through the fan cover 4 and the vents 3, adhering to the surface of the server equipment, or blocking the heat dissipation gaps. This design reduces the corrosion of heat dissipation components and server equipment by dust, lowering the probability of equipment failure caused by dust.
[0030] refer to Figure 1 A cabinet door 12 is hinged to the left side of the front of the server cabinet 1, and an observation window 13 is provided on the front of the cabinet door 12.
[0031] As a technical optimization of this utility model, the combination design of cabinet door 12 and observation window 13 ensures equipment safety while also taking into account ease of operation and heat dissipation stability. Cabinet door 12 can provide physical protection for the server equipment inside the cabinet, preventing external collisions, accidental contact, and the entry of foreign objects, thus creating a safe operating environment for the equipment; while observation window 13 allows staff to directly observe the operating status of the equipment without opening cabinet door 12.
[0032] The working principle and usage process of this utility model are as follows: First, place the server cabinet 1 in a well-ventilated and dry environment, avoiding prolonged exposure to direct sunlight or dampness, and ensuring sufficient space around the cabinet to guarantee air circulation. Then, conduct a comprehensive inspection of all cabinet structures, confirming that the cabinet door 12 opens and closes smoothly, the observation window 13 is free of scratches and has good transparency, the dust filter and dustproof mesh frame 8 are undamaged or deformed, the heat-conducting strip 10 is tightly connected to the cabinet without loosening, there is no air leakage at the connection between the air intake pipe 5 and the blower 11, and the fan 6 is securely fixed to the bracket. Next, perform the equipment installation operation, fixing the server or computer network equipment to be used to the mounting bracket 14 on the top of the partition 2 with screws, ensuring stable installation, while maintaining a certain gap between the bottom of the equipment and the partition 2 to provide space for airflow.
[0033] After the equipment is fixed in place, arrange all connecting cables through the cable access ports on the back of the cabinet, and seal the ports with the sealing rings to prevent cable damage and dust from entering. After installation, close the cabinet door 12 and check the equipment placement through the observation window 13. Then, connect the power to the fan 6 and the external air pump. After starting the fan 6, outside air enters the intake pipe 5 after being filtered by the dust filter, and is then gathered by the fan shroud 4 and blown onto the equipment through the vents 3, carrying away the heat generated by the equipment. The heated air rises through the vents 9 and is finally discharged from the cabinet through the dustproof mesh frame 8. At the same time, start the external air pump, and the airflow enters the blower 11 through the pipe. The blower 11 blows air downwards onto the end of the heat-conducting strip 10 located outside the cabinet to accelerate heat dissipation.
