Description

Technical Field

[0001] This utility model belongs to the field of server rack technology, specifically relating to a server rack with high-efficiency heat dissipation. Background Technology

[0002] Server racks are critical infrastructure components in data centers used to install and organize hardware such as servers, network equipment, and storage systems. They not only provide physical support but also integrate functions such as power distribution, cooling management, and cable management to ensure efficient operation and ease of maintenance. However, servers generate significant heat during operation, and if this heat is not dissipated effectively and promptly, it can lead to performance degradation, shortened lifespan, and even equipment failure. Therefore, optimizing the heat dissipation performance of server racks is a crucial technical issue of concern in the industry.

[0003] A patent with publication number CN208569510U discloses an energy-saving cooling device for computer servers. This device includes a server chassis with an air inlet and an air outlet positioned opposite each other on its side walls. An exhaust fan is installed at the air outlet. The device also includes a T-shaped cooling unit, comprising a water tank fixed to the top of the chassis and at least one hot water collection pipe inserted from the top of the chassis into the chassis cavity. The water tank and the hot water collection pipe are connected. During operation, heat generated by the internal components of the chassis is dissipated into the air inside the chassis. The hot air then flows through the gaps between the hot water collection pipes under the action of the exhaust fan. The water pipes carry away some of the heat from the hot air, which is then dissipated to the outside of the chassis via the top water tank. The remaining hot air is exhausted from the chassis through the air outlet under the action of the exhaust fan, thus achieving heat dissipation.

[0004] While this technology effectively cools the hot air inside the server rack via hot water pipes and a cooling tank, it has certain drawbacks: the server rack has hot water pipes at the air outlet for cooling the servers, recovering heat from the air before exhausting it. This method of cooling the air at the server outlet means the cooled air doesn't re-contact the server, thus failing to further reduce the server's surface temperature, impacting the cooling effect and limiting the rack's overall heat dissipation efficiency.

[0005] To address these issues, existing technologies have attempted to combine water cooling and air cooling to improve heat dissipation performance. However, many existing water cooling systems are complex in structure, occupy a large space, and have poorly designed coolant circulation paths, resulting in low heat transfer efficiency. Furthermore, energy consumption has become a significant limiting factor in the context of increasingly stringent energy-saving requirements. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a server rack with high-efficiency heat dissipation. It can achieve efficient circulation and heat exchange of coolant by combining air cooling and liquid cooling methods, using cooling boxes and circulation components. At the same time, it optimizes the air flow path, improves the heat dissipation efficiency inside the rack, and thus significantly improves the cooling effect of the server.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-efficiency heat dissipation server rack includes a rack with an opening on the front side and a door that rotates through the opening. An exhaust fan is fixedly installed on the top surface of the rack, and a cooling box is installed on the bottom surface of the rack. A guide tube rod is vertically fixed from the top surface of the cooling box to the bottom surface, and multiple guide tube rods are evenly and vertically arranged on the cooling box. The top surface of the cooling box is fixedly installed on the bottom surface of the rack, and a circulation component is installed below the cooling box. The circulation component includes two circulating water cylinders and two distribution pipes symmetrically arranged on both sides of the cooling box. The distribution pipe is horizontally installed below the cooling box, and both ends of the distribution pipe are connected and fixed to the bottom surface of the circulating water cylinders. The top end of the circulating water cylinders is connected and assembled to the side end face of the cooling box, and one end of the distribution pipe is connected and assembled to a circulation pump.

[0009] Furthermore, a screw tube is horizontally installed at the top of the circulating water cylinder, and one end of the screw tube is rotatably connected to the top of the circulating water cylinder.

[0010] Furthermore, screw barrel seats are horizontally connected and fixed on both vertical end faces of the cooling box, and the screw barrel seats are threadedly connected and assembled with the screw barrel connecting pipe.

[0011] Furthermore, heat exchange rings are fixed on the outer circumferential surface of the circulating water cylinder and the outer wall of the diversion pipe, and multiple heat exchange rings are evenly arranged on the outer circumferential surface of the circulating water cylinder and the outer wall of the diversion pipe.

[0012] Furthermore, sleeves are horizontally installed on both symmetrical vertical end faces inside the cabinet, and multiple sleeves are installed along the vertical direction, with one end of each sleeve fixed to the inner wall of the cabinet.

[0013] Furthermore, the cabinet has symmetrical horizontal support frames on both sides inside, and a guide rod is horizontally fixed on one end of the support frame near the sleeve, and the guide rod is horizontally slidably inserted into the sleeve.

[0014] Furthermore, a spring is horizontally sleeved on the outside of the guide rod, and the two ends of the spring are fixed to the guide rod and the sleeve, respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention provides a high-efficiency heat dissipation server rack. By incorporating a cooling box and air guide rods at the bottom of the rack, combined with a top exhaust fan, airflow creates a bottom-up cooling path. Multiple evenly distributed air guide rods within the cooling box, aided by coolant, effectively reduce air temperature and guide the cooled air into the rack, where it contacts the servers. After further absorbing heat, the air is exhausted by the exhaust fan, significantly improving the cooling effect on the servers and solving the problem in traditional technologies where the cooling air at the rear cannot re-contact the servers.

[0017] This invention establishes a highly efficient coolant circulation system by incorporating circulation components, including a circulating water tank, a distribution pipe, and a circulating pump. During circulation, the coolant exchanges heat with the outside air through the heat exchange rings of the circulating water tank and the distribution pipe, improving heat dissipation efficiency. Simultaneously, it ensures that the coolant temperature remains within a reasonable range, thereby enhancing the stability and durability of the cooling system. This solves the problems of low heat transfer efficiency and difficult system maintenance in existing water-cooling technologies.

[0018] In the internal design of this utility model's cabinet, support frames and sleeves are set on both vertical end faces, and the server equipment is stably installed and its position adjusted through guide rods and spring structures. The sliding connection between the support frames and guide rods not only facilitates flexible equipment arrangement, but also reduces the impact of vibration on the equipment through the elastic buffering effect of the springs, thereby improving the safety and stability of server operation and meeting the adaptability requirements of high-efficiency heat dissipation cabinets in different usage scenarios.

[0027] Example 1:

[0028] refer to Figures 1-5 As shown, a high-efficiency heat dissipation server rack includes a rack 1. The front face of the rack 1 has an opening, and a door 2 is rotatably mounted at the opening. The door 2 is hinged to the rack 1 for easy opening and closing, facilitating the installation and maintenance of the servers inside the rack 1. An exhaust fan 11 is fixedly mounted on the top surface of the rack 1. The exhaust fan 11 is driven by a motor and is used to exhaust hot air from inside the rack 1, thereby accelerating air circulation and ensuring heat dissipation efficiency. A cooling box 3 is mounted on the bottom surface of the rack 1. A guide pipe rod 31 is vertically mounted on the top surface of the cooling box 3, extending from the bottom surface. Multiple guide pipe rods 31 are evenly and vertically mounted on the cooling box 3. The guide pipe rod 31 has a hollow internal structure to guide external cold air into the rack. Inside the cabinet 1, the top surface of the cooling box 3 is fixed to the bottom surface of the cabinet 1, and a circulation component 4 is provided below the cooling box 3. The circulation component 4 includes a circulating water cylinder 41 and a distribution pipe 42. There are two circulating water cylinders 41, which are symmetrically arranged on both sides of the cooling box 3. The circulating water cylinders 41 are used to store coolant and transfer heat through the flow inside them. The distribution pipe 42 is horizontally arranged below the cooling box 3, and its two ends are respectively connected to and fixed to the bottom surface of the circulating water cylinder 41, which is used to connect the circulating water cylinder 41 and the cooling box 3 for coolant circulation. The top of the circulating water cylinder 41 is connected to the side end face of the cooling box 3, and one end of the distribution pipe 42 is connected to a circulation pump 44. The circulation pump 44 provides driving force for the entire coolant circulation system, ensuring the continuity and efficiency of coolant flow.

[0029] refer to Figure 2 and Figure 3As shown, a screw tube 43 is horizontally installed at the top of the circulating water tank 41. One end of the screw tube 43 is rotatably connected to the top of the circulating water tank 41. The inside of the screw tube 43 is a channel structure, which allows the coolant to flow through the circulating water tank 41 to the cooling box 3. The connection is made sealed and removable through a threaded connection, which facilitates maintenance.

[0030] refer to Figure 3 and Figure 4 As shown, screw barrel seats 32 are horizontally connected and fixed on both vertical end faces of the cooling box 3. The screw barrel seats 32 are threadedly connected to the screw barrel connecting pipe 43. The interior of the screw barrel seats 32 adopts a sealed design to prevent the coolant from leaking during the flow process, and at the same time improve the stability of the connecting parts.

[0031] refer to Figure 3 and Figure 4 As shown, heat exchange rings 45 are fixed on the outer circumferential surface of the circulating water cylinder 41 and the outer wall of the diversion pipe 42. The heat exchange rings 45 are made of metal and are used to increase the heat dissipation area of ​​the circulating water cylinder 41 and the diversion pipe 42. Multiple heat exchange rings 45 are evenly arranged on the outer circumferential surface of the circulating water cylinder 41 and the outer wall of the diversion pipe 42. The heat exchange rings 45 are spaced at a reasonable distance to ensure smooth airflow and to remove heat through airflow, thereby improving the heat dissipation effect.

[0032] refer to Figure 5 As shown, sleeves 12 are horizontally arranged on both symmetrical vertical end faces inside the cabinet 1. Multiple sleeves 12 are arranged in the vertical direction. One end of the sleeve 12 is fixed to the inner wall of the cabinet 1, and the other end is open for sliding installation of guide rods 14. The sleeves 12 provide support and guidance for the guide rods 14 to ensure smooth movement of the guide rods 14.

[0033] refer to Figure 5 As shown, symmetrical horizontal brackets 13 are arranged on both sides of the inside of the cabinet 1. A guide rod 14 is horizontally fixed on one end face of the bracket 13 near the sleeve 12. The guide rod 14 is horizontally slidably inserted into the sleeve 12. The bracket 13 is used to install server equipment, and the position of the bracket 13 is adjusted by sliding the guide rod 14.

[0034] refer to Figure 5 As shown, a spring 15 is horizontally sleeved on the outside of the guide rod 14. The two ends of the spring 15 are fixed to the guide rod 14 and the sleeve 12 respectively. The spring 15 is used to provide elastic support. When the guide rod 14 is subjected to external force, the spring 15 can generate corresponding elastic deformation, thereby ensuring the installation stability of the bracket 13 and reducing the impact of vibration on the server equipment.

[0035] Example 2:

[0036] To verify the high-efficiency heat dissipation effect of this invention, a server rack with dimensions of 2000mm × 800mm × 600mm was selected. A cooling box 3 was installed at the bottom of the rack 1, and 12 air guide rods 31 with a diameter of 40mm were arranged inside the cooling box 3. These rods were made of high thermal conductivity aluminum alloy. The coolant was an industrial-grade ethylene glycol aqueous solution, and the coolant temperature was controlled at 10℃. Liquid circulation was achieved through a circulation component 4. An exhaust fan 11 with a diameter of 300mm and a rotation speed of 2000rpm was installed at the top of the rack 1 to forcibly extract hot air from inside the rack. During testing, the total power of the server equipment was set to 10kW. After 24 hours of operation, the internal temperature of the rack dropped from 50℃ to 35℃, improving the cooling efficiency by 30%. Measurements of the heat transfer efficiency of the air guide rod walls revealed that each air guide rod could absorb 30W of heat per unit time, significantly improving the cooling capacity of the air inside the rack.

[0037] Example 3:

[0038] To verify the performance of the circulating coolant system, a 10L circulating water tank 41 and a 20mm diameter manifold 42 were selected. The circulating water tank was made of 304 stainless steel, with 40 2mm thick aluminum heat exchange rings 45 evenly distributed on its outer wall. A low-power circulating pump 44, model GPD25-10-3, with a flow rate of 15L / min, was used. The coolant circulated between the cooling box 3 and the circulating water tank 41, maintaining a temperature difference within 10℃. Infrared imaging was used to observe the heat dissipation effect of the heat exchange rings, revealing that it could reduce the coolant temperature from 30℃ to 20℃ within 10 minutes. During the experiment, the circulation stability and heat transfer efficiency of the coolant were tested. The results showed that the system maintained high-efficiency heat dissipation performance after 24 hours of operation, with the circulating liquid temperature change range less than 2℃.

[0039] Example 4:

[0040] To verify the seismic performance of the rack and sleeve inside the server rack, guide rod 14 was selected, made of 45# steel, 300mm long, 10mm in diameter, and chrome-plated to improve wear resistance. Spring 15 was a compression spring with an elastic modulus of 2000N / m, with both ends fixed to guide rod 14 and sleeve 12 respectively. In the experiment, a server device with a total mass of 50kg was installed on rack 13, and the rack was vibrated using a vibration table with a frequency of 5Hz. The displacement of the server device was monitored. The results showed that the combination of guide rod and spring could effectively absorb vibration energy, reducing the amplitude of the server device from the original 10mm to 3mm, with a vibration attenuation efficiency of up to 70%. In addition, the connection structure between rack 13 and guide rod 14 remained stable, with no slippage or loosening.

[0041] The working principle of this utility model is as follows: When in use, the exhaust fan 11 on the top surface of the cabinet 1 is started, which drives the external air to enter from the bottom surface of the cooling box 3 on the bottom surface of the cabinet 1. The air is guided into the cabinet 1 through multiple air guide rods 31 on the cooling box 3. When the air flows in the air guide rods 31, the air contacts the tube wall of the air guide rods 31 and transfers heat into the tube wall of the air guide rods 31. The air guide rods 31 contact the coolant in the cooling box 3 and transfer heat to the coolant. The circulation pump 44 at one end of the diversion pipe 42 in the circulation component 4 is started, which drives the coolant in the circulating water tank 41 on one side to flow through the diversion pipe 42 to the circulating water tank 41 on the other side. Then, the coolant is guided into the cooling box 3 through the screw tube 43. The coolant is driven by the circulation pump 44 to circulate in the cooling box 3, the two circulating water cylinders 41 and the diversion pipe 42. When the coolant flows in the two circulating water cylinders 41 and the diversion pipe 42, the internal heat is dissipated by contacting the outside air through the pipe walls of the two circulating water cylinders 41 and the diversion pipe 42. Thus, the air entering the rack 1 is first cooled in the cooling box 3, which improves the heat storage capacity of the air entering the rack 1. Then, the air in the rack 1 comes into contact with the servers installed inside, carrying heat and is discharged from the exhaust fan 11 on the top surface of the rack 1, which improves the heat dissipation and cooling effect on the servers.

[0042] In order to facilitate server support during use, the server is placed on the support frame 13. The server supports the support frame 13, causing the guide rod 14 to slide in the sleeve 12, compressing the spring 15 to deform. The deformation force of the spring 15 pushes the support frame 13 to slide in the sleeve 12, thereby driving the support frame 13 to press and compress the server to improve the stability of the installation.

[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
