Description
Technical Field
[0001] The utility model relates to the technical field of servers, and particularly relates to a distributed heat dissipation structure and a blade server. Background Art
[0002] A blade server is a high-density, modular server design that vertically inserts multiple server modules (or "blade modules") into a large rack-mounted chassis, sharing power, cooling, network, and storage resources. This design optimizes space utilization, reduces energy consumption and operating costs, and improves system reliability and maintainability. Blade servers are suitable for environments that require large-scale computing power and high availability, such as data centers, cloud computing platforms, and complex computing tasks, and they can provide flexible expansion options to meet changing computing needs.
[0003] The heat dissipation design of a blade server is crucial because its high-density configuration generates a large amount of heat. Generally, a cooling system installs fans inside the whole machine. The fans are generally axial fans, and the heat is forced to be transferred from the heat source to the external environment by the rotation of the fans. Since a large amount of heat is generated when the blade server is working, large fans with high power and high rotation speed are required to perform forced air cooling on it.
[0004] However, in order to provide sufficient air volume and air pressure, the fans need to run at high speeds, which causes the fan blades to quickly cut the air, generating aerodynamic noise. In addition, the high-speed air flow generated by the fans interacts with various structural components (such as circuit boards, cables, heat sinks, etc.) inside the chassis to form turbulence. These turbulences will excite structural vibrations to generate noise, and the turbulences are not conducive to the discharge of hot air. Summary of the Utility Model

[0038] A blade server is a high-density, modular server design that vertically inserts multiple server modules (or "blade modules") into a large rack-mounted chassis, sharing power, cooling, network, and storage resources. This design optimizes space utilization, reduces energy consumption and operating costs, while improving system reliability and maintainability. Blade servers are suitable for environments that require large-scale computing power and high availability, such as data centers, cloud computing platforms, and complex computing tasks. They can provide flexible expansion options to meet changing computing needs.
[0039] The heat dissipation design of blade servers is crucial because their high-density configuration generates a large amount of heat. Generally, a fan is installed inside the whole machine, and the fan is usually an axial flow fan. By rotating the fan, heat is forced to be transferred from the heat source to the external environment. Since a large amount of heat is generated when the blade server is working, a large fan with high power and high rotation speed is required for forced air cooling.
[0040] However, in order to provide sufficient air volume and air pressure, the fan needs to operate at a high rotation speed, which causes the fan blades to cut the air quickly, generating aerodynamic noise. In addition, the high-speed air flow generated by the fan interacts with various structural components (such as circuit boards, cables, heat sinks, etc.) inside the chassis, forming turbulence. These turbulences will excite structural vibrations to generate noise, and the turbulences are not conducive to the discharge of hot air.
[0041] To solve the above problems, the present utility model proposes a distributed heat dissipation structure and a blade server, aiming to provide a distributed heat dissipation structure with relatively less noise and easier heat export. Figures 1 to 7 It is a schematic structural diagram of an embodiment provided for the distributed heat dissipation structure of the present utility model.
[0042] Please refer to Figures 1 to 7 , the present utility model proposes a distributed heat dissipation structure 1000, including a housing 1, a heat dissipation component 2, and a blade module 3. The housing 1 is provided with a receiving cavity having an air inlet 1a and an air outlet 1b. The heat dissipation component 2 includes a plurality of spaced-apart heat dissipation parts 21. Two partition plates 4 are provided between every two adjacent heat dissipation parts 21. The two partition plates 4 enclose to form an installation cavity 41. Each heat dissipation part 21 includes a plurality of vortex fans 211. The vortex fans 211 are provided with an air inlet end 211a along the axial direction and an air outlet end 211b along the radial direction. The air inlet end 211a is closely attached to the partition plate 4, and the air outlet end 211b faces the air inlet 1a. The blade module 3 is arranged in the installation cavity 41, and the two side walls of the blade module 3 are attached to the two partition plates 4.
[0043] In the technical solution of the present utility model, a distributed heat dissipation structure 1000 and a blade server are proposed. Among them, the distributed heat dissipation structure 1000 includes a housing 1, a heat dissipation component 2, and a blade module 3. The housing 1 is provided with a receiving cavity having an air inlet 1a and an air outlet 1b. The heat dissipation component 2 includes a plurality of spaced-apart heat dissipation parts 21. Between every two adjacent heat dissipation parts 21, two partition plates 4 are provided. The two partition plates 4 enclose to form an installation cavity 41. Each heat dissipation part 21 includes a plurality of vortex fans 211. The vortex fans 211 are provided with an air inlet end 211a along the axial direction and an air outlet end 211b along the radial direction. The air inlet end 211a is closely attached to the partition plate 4, and the air outlet end 211b faces the air inlet 1a. On both sides of each blade module 3, a unique air duct 1c is provided. The air duct 1c communicates the air inlet 1a and the air outlet 1b. The heat dissipation parts 21 are arranged in the air duct 1c. Each air duct 1c is independent of each other. When the vortex fans 211 are started, cold air will enter the air duct 1c from the air inlet 1a under the action of the vortex fans 211, fully exchange heat with the blade module 3, and the blade module 3 will quickly cool down. The heated air after absorbing heat is led out from the air outlet 1b. During the whole process, the flowing air will not interact with other structures, and it is not easy to generate turbulence, thereby reducing the noise of the equipment and optimizing the heat dissipation effect.
[0044] Specifically, reference can be made to Figure 7 , and the direction indicated by the arrow is the flowing direction of the air. The air enters the air duct 1c from the air inlet 1a, completes the heat exchange and is then led out from the air outlet 1b.
[0045] In the technical solution of the present utility model, each heat dissipation part 21 can operate independently and be intelligently adjusted according to the real-time temperature of different blade modules 3. Specifically, on one side of each partition plate 4 facing a blade module 3, a temperature monitoring device 6 is provided. Specifically, please further refer to Figure 2 and Figure 3, the distributed heat dissipation structure 1000 further includes a main control board 5, which is electrically connected to the temperature monitoring device 6 and the vortex fan 211 respectively. By adopting the distributed heat dissipation structure 1000 and combining the temperature monitoring device 6 facing the blade module 3 on each partition board 4, and the main control board 5 electrically connected to these devices for PID speed regulation heat dissipation design, the following advantages are achieved: First, this design realizes precise temperature monitoring of each blade module 3 in the blade server, and can respond to the temperature changes in local hot spots in real time. Second, through PID speed regulation, the main control board 5 can dynamically adjust the fan speed according to the data provided by the temperature monitoring device 6 to adapt to the current heat load and achieve more efficient heat management. In addition, this intelligent heat dissipation control reduces unnecessary energy consumption because the vortex fan 211 only operates at an appropriate speed when necessary, reducing power consumption and noise levels. At the same time, this active heat management strategy helps to extend the service life of server components and improve the stability and reliability of the system. Finally, the flexibility and modular characteristics of the distributed heat dissipation structure 1000 enable it to adapt to the server requirements of different scales and configurations, providing an efficient, energy-saving and scalable heat dissipation solution for data centers and server rooms.
[0046] Further, in an embodiment of the present invention, the heat dissipation part 21 includes two vortex fans 211, which are arranged at intervals in the vertical direction. The air outlet ends 211b of the two vortex fans 211 both face the air outlet 1b, and the air inlet ends 211a of the vortex fans 211 are closely attached to the partition board 4. The two vortex fans 211 respectively act on the heat dissipation of the upper part and the lower part of the blade module 3, ensuring that the hot air can be effectively discharged from both the upper part and the lower part, and avoiding the generation of local hot spots. Second, the setting of the double vortex fans 211 improves the heat dissipation efficiency, can more quickly export the heat from the key components, reduces the working temperature of the equipment, and thus improves the system stability and performance. In addition, this layout helps to balance the load of the vortex fans 211, extends the service life of the vortex fans 211, and reduces the risk of single-point failure caused by the failure of the vortex fans 211. At the same time, the heat dissipation design in the vertical direction can also reduce the resistance of air flow, optimize the efficiency of the air duct 1c, reduce noise, and improve the energy efficiency ratio of the overall heat dissipation system. In another embodiment of the present invention, the heat dissipation part 21 includes two groups of vortex fans 211, with two vortex fans 211 in each group, which are arranged at intervals in the vertical direction. The air outlet ends 211b of the two vortex fans 211 both face the air outlet 1b. Compared with the heat dissipation solution with two vortex fans 211, setting four vortex fans 211 can further improve the heat dissipation efficiency, so as to ensure the normal operation of the blade module 3.
[0047] For installing the turbofan 211, the distributed heat dissipation structure 1000 further includes a mounting plate 42. It should be noted that the mounting plate 42 can be made of polyurethane material or hard rubber material. The present utility model does not limit this. In an embodiment of the present utility model, the mounting plate 42 is made of polyurethane material. The mounting plate 42 made of polyurethane material has various advantages. First of all, as a high polymer damping material, polyurethane can effectively convert vibration energy into heat energy due to its high loss factor and excellent damping performance, reduce vibration transmission, and thus reduce noise and resonance. Secondly, polyurethane material has good sound absorption performance, which can absorb and reduce the reflection of sound waves, further reducing noise. In addition, polyurethane material usually has high strength and wear resistance, making it perform well under mechanical stress and daily use.
[0048] To export the hot air at the lower bottom of the accommodation cavity of the distributed heat dissipation structure 1000, the distributed heat dissipation structure 1000 further includes an axial flow fan 8. Specifically, please further refer to Figure 6 , the axial flow fan 8 is arranged in the accommodation cavity and at the bottom of the accommodation cavity. With such a setting, the hot air in the dead corner area can be exported, greatly improving the overall heat dissipation effect.
[0049] To further optimize the heat dissipation efficiency, in an embodiment of the present utility model, the distributed heat dissipation structure 1000 further includes a cooling coil 7. Specifically, please further refer to Figure 5 , the cooling coil 7 is arranged between two groups of turbofans 211 and is attached to the partition plate 4. When the heat dissipation requirement of the blade server is large, flowing water can be provided by connecting an external water storage tank and a water pump, and the heat generated by the operation of the blade module 3 can be taken away by the flow of water; if the heat dissipation requirement of the blade server is not large, water can also be injected into the cooling coil 7 and replaced regularly. The cooling coil 7 increases the heat dissipation area and improves the heat dissipation efficiency.
[0050] To facilitate the installation and disassembly of internal components, the housing 1 includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are fixed by means of buckles or screwing. When internal components need to be repaired and replaced, the upper housing 11 can be removed to complete the maintenance work.
[0051] The present utility model also proposes a blade server, which includes a distributed heat dissipation structure 1000. The specific structure of the distributed heat dissipation structure 1000 refers to the above embodiments. Since this blade server adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.
[0052] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
