Description

Technical Field

[0001] This invention relates to the field of composite heat dissipation cabinet technology, specifically a data center cabinet with optimized heat dissipation performance. Background Technology

[0002] In the era of big data, the digital economy has become a key tool for countries to achieve economic recovery and promote transformation and upgrading. Economic development is also accelerating its shift from physical space to digital space, and gradually shifting from land, manpower, and machines to data, algorithms, and computing power.

[0003] As server rack sizes increase and power densities rise, unreasonable internal airflow organization leads to eddies, mixing of hot and cold air, and significant temperature gradients along the height, resulting in prominent local hot spots. Simultaneously, cooling systems consume high energy, and existing research often focuses solely on heat dissipation speed while neglecting energy consumption, lacking evaluation metrics and optimal operating parameters that balance cooling performance and energy efficiency. Furthermore, traditional rack-level cooling research fails to address the uniformity of cooling across server layers, making it difficult to resolve localized thermal safety issues within individual racks. Therefore, there is an urgent need to improve rack cooling performance and reduce energy consumption by optimizing airflow organization, determining the optimal server layout, and establishing the best operating parameters for the cooling system. Summary of the Invention

[0004] The purpose of this invention is to provide a data center cabinet with optimized heat dissipation performance to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a data center cabinet with optimized heat dissipation performance, comprising a cabinet assembly, wherein hot aisles and cold aisles are fixedly connected to both sides of the cabinet assembly, and an elevated base is fixedly connected to the bottom of the cabinet assembly, wherein both sides of the surface of the elevated base are fixedly connected to the bottom of the hot aisles and cold aisles, respectively. A composite heat dissipation system is provided on one side of the cold aisle, and the interior of the cabinet assembly is fixedly connected to one side of a temperature regulator. The hot aisle and cold aisle are separated to effectively avoid mixing of hot and cold air, reduce the generation of eddies, alleviate the problem of temperature gradient in the height direction, and reduce the probability of local hot spots. The elevated base provides installation space for heat dissipation components and is fixedly connected to the hot and cold aisles to ensure structural stability and optimize the airflow path.

[0006] Preferably, the enclosure assembly includes a main body, with a connecting frame fixedly connected to the inner cavity of the main body. Four servers are movably connected to the middle of the connecting frame. Four cast aluminum heating plates and four axial flow fans are fixedly connected to the top of the four servers, respectively. The four cast aluminum heating plates and four axial flow fans are electrically connected via wires. One side of each of the four cast aluminum heating plates passes through the main body and is electrically connected to one side of the temperature gearbox. Firstly, the connecting frame provides a stable mounting base for the servers, and the movable connection facilitates server maintenance and expansion, adapting to the flexible use requirements of the rack. Secondly, the cast aluminum heating plates accurately simulate server heat generation, and the axial flow fans enhance forced convection heat transfer, quickly removing server heat and alleviating localized hotspots. Thirdly, the electrical connection between the two and the temperature gearbox allows for real-time monitoring of the heating status and feedback adjustment, ensuring a match between heat dissipation and heat generation. Fourthly, this structure forms a collaborative system between the servers, heat source simulation, and heat dissipation components, providing accurate physical model support for subsequent CFD simulations, assisting in airflow organization optimization and heat dissipation parameter debugging, ultimately improving the rack's heat dissipation efficiency and operational stability.

[0007] Preferably, a coil fan is fixedly connected to the middle of the inner cavity of the overhead base, and an inner tube is fixedly connected to the inner cavity of the coil fan. Two second connecting pipes and a fan speed controller are fixedly connected to the other side of the overhead base. The coil fan and the inner tube work together to provide key support for the combined air cooling and water cooling heat dissipation. Cooling water is introduced into the inner tube to quickly cool the airflow. Combined with the forced convection of the fan, the heat dissipation efficiency is significantly improved, and the problem of local hot spots is alleviated.

[0008] Preferably, the composite heat dissipation system includes a water pressure pump, a control water valve pipe fixedly connected to one side of the water pressure pump, a water storage tank fixedly connected to the other end of the control water valve pipe, an outlet pipe fixedly connected to the top of the water pressure pump, a flow meter fixedly connected to one end of the outlet pipe, and the other end of the flow meter fixedly connected to the inner cavity of one of the second connecting pipes. The water pressure pump provides stable power for the cooling water circulation, ensuring that the cooling medium is efficiently delivered to the core heat dissipation area. In conjunction with the water storage tank, it realizes the storage and replenishment of cooling water, ensuring the continuity of heat dissipation. The control water valve pipe can flexibly adjust the flow of cooling water to adapt to the heat dissipation requirements under different operating conditions and avoid ineffective energy consumption.

[0009] Preferably, a water pump speed regulator is fixedly connected to one end of the water pressure pump, a first connecting pipe is provided on the top of the water storage tank, a ball valve is fixedly connected to one end of the first connecting pipe, and one end of the ball valve is fixedly connected to another second connecting pipe. A thermostat is fixedly connected to the top of the fan speed regulator via an electrical wire, and the electrical wires on the surface of the thermostat are electrically connected to the whole system. The output ends of the first connecting pipe and the water outlet pipe pass through the overhead base and the coil fan, and are fixedly connected to both ends of the inner tube of the coil fan. This allows the water pump speed regulator to flexibly adjust the cooling water flow rate, and, in conjunction with the thermostat, achieve precise control of the entire system. First, precise control ensures that the heat dissipation effect dynamically matches the server's heat demand, avoiding energy waste. Second, the ball valve, in conjunction with the first and second connecting pipes, constructs a stable and controllable liquid circulation system, facilitating rapid on / off switching of cooling water and adapting to different operating conditions. Third, each pipe is precisely connected to the coil's internal tubes, ensuring efficient cooling water delivery, enhancing the synergistic heat exchange effect with the coil fan, and improving the overall heat dissipation efficiency. Fourth, the temperature controller is electrically connected to the entire system, enabling real-time linkage adjustment of heat-generating and heat-dissipating components to ensure stable internal temperature of the cabinet, effectively alleviating local hot spots and temperature gradient problems, and helping the system reach its optimal operating state.

[0010] Preferably, a return air valve and an outlet air valve are fixedly connected to one side of the elevated base and the hot channel, respectively. The outer surfaces of the main body, cold channel, hot channel, and elevated base are all covered with a first layer of insulation cotton, and the outer surfaces of the temperature controller and water pump speed controller are all covered with a second layer of insulation cotton. Firstly, the return air valve and outlet air valve precisely control the airflow in and out, and combined with the separate design of the cold and hot channels, reduce the mixing and turbulence of cold and hot air, ensuring reasonable airflow organization and improving heat dissipation efficiency. Secondly, the first layer of insulation cotton fully covers the main body, cold and hot channels, and elevated base, effectively reducing heat exchange between the interior and the outside, preventing cold loss and heat penetration, and reducing heat dissipation energy consumption. Thirdly, the second layer of insulation cotton specifically protects the temperature controller and water pump speed controller, preventing the influence of ambient temperature on the control components, ensuring their operational stability and control accuracy. The overall design takes into account both airflow control and thermal insulation, providing dual protection for stable internal temperature and efficient operation of the heat dissipation system, helping to solve the problems of local hot spots and high energy consumption.

[0011] Compared with the prior art, the beneficial effects of the present invention are: This invention addresses the heat dissipation challenges of data center server racks by designing a rack structure with separate hot and cold aisles. Combined with an elevated base and a composite cooling system, it creates an intelligent cooling solution integrating air and water cooling. The rack allows for flexible server installation via a connecting frame. Cast aluminum heating plates and axial fans work together to simulate and remove heat from the heat source. Components such as temperature controllers and temperature gauges work in tandem to monitor and adjust equipment operation in real time. The composite cooling system utilizes a water pump and coil fans to create a controllable liquid circulation path, switching cooling modes according to different winter and summer conditions. Air valves precisely regulate airflow paths, and double-layer insulation provides thermal protection. This effectively prevents the mixing of hot and cold air, alleviates localized hot spots and temperature gradients, improves cooling efficiency and equipment stability, and significantly reduces ineffective energy consumption. Furthermore, the rack's structural design also considers the practical needs of server maintenance and expansion. Attached Figure Description

[0015] Please see Figure 1-4This invention provides a data center cabinet with optimized heat dissipation performance, including a cabinet assembly 15. Hot aisles 3 and cold aisles 10 are fixedly connected to both sides of the cabinet assembly 15, and an overhead base 6 is fixedly connected to the bottom of the cabinet assembly 15. The two sides of the surface of the overhead base 6 are fixedly connected to the bottom of the hot aisles 3 and the cold aisles 10, respectively. A composite heat dissipation system 16 is provided on one side of the cold aisle 10. The interior of the cabinet assembly 15 is fixedly connected to one side of a temperature gearbox 26. The cold aisle 10, hot aisle 3, and cabinet assembly 15 are collectively referred to as the cabinet system. In winter, air enters directly from the return air valve 5, flows inside, and finally flows out from the exhaust air valve 4. In summer, the composite heat dissipation system 16 on one side is required for heat dissipation.

[0016] Furthermore, the enclosure assembly 15 includes a main body 1, with a connecting frame 17 fixedly connected to the inner cavity of the main body 1. Four servers 18 are movably connected to the middle of the connecting frame 17. Four cast aluminum heating plates 2 and four axial flow fans 9 are fixedly connected to the top of the four servers 18, respectively. The four cast aluminum heating plates 2 and the four axial flow fans 9 are electrically connected by wires. One side of each of the four cast aluminum heating plates 2 passes through the main body 1 and is electrically connected to one side of the temperature gearbox 26. First, the four servers 18 are inserted into the connecting frame 17. If they are unstable, they can be tied with ropes made of high-temperature resistant material. When the placement is complete, the wires of the cast aluminum heating plates 2 can be inserted into the four cast aluminum heating plates 2, and then connected to the external temperature gearbox 26.

[0017] Furthermore, a coil fan 7 is fixedly connected to the middle of the inner cavity of the overhead base 6, and an inner tube 8 is fixedly connected to the inner cavity of the coil fan 7. Two second connecting pipes 28 and a fan speed controller 25 are fixedly connected to the other side of the overhead base 6. External air flows in through the return air valve 5. When used in summer, the water cooled by the composite heat dissipation system 16 can flow from the second connecting pipe 28 into the inner tube 8 to cool the incoming air.

[0018] Furthermore, the composite heat dissipation system 16 includes a water pressure pump 13, a control water valve pipe 24 fixedly connected to one side of the water pressure pump 13, a water storage tank 14 fixedly connected to the other end of the control water valve pipe 24, an outlet pipe 23 fixedly connected to the top of the water pressure pump 13, a flow meter 12 fixedly connected to one end of the outlet pipe 23, and the other end of the flow meter 12 fixedly connected to the inner cavity of one of the second connecting pipes 28. A water pump speed controller 21 is fixedly connected to one end of the water pressure pump 13. A first connecting pipe 22 is provided on the top of the water storage tank 14. A ball valve 11 is fixedly connected to one end of the first connecting pipe 22, and one end of the ball valve 11 is fixedly connected to another second connecting pipe 28. A thermostat 20 is fixedly connected to the top of the fan speed controller 25 via an electrical wire. The wires on the surface of the thermostat 20 are electrically connected to the whole system. The output ends of the first connecting pipe 22 and the water outlet pipe 23 pass through the overhead base 6 and the coil fan 7 and are fixedly connected to both ends of the inner tube 8. The coil fan 7 is adjusted by the fan speed controller 25, with three speeds. The entire liquid circuit system in the heat dissipation device is located outside the overhead base 6. A six-point copper head corrugated pipe is used as the water supply channel to transport the cooling water. Considering the viscosity of the liquid, the height of the water tank 14 and the pipe loss, the water pressure pump 13 is finally selected. The water flow rate can be adjusted by the water pump speed controller 21. A flow meter 12 is installed in the pipeline to read the cooling water flow rate information. The thermostat 20 is connected to the cast aluminum heating plate 2 in the cabinet system to adjust its surface temperature.

[0019] Furthermore, a return air valve 5 and an outlet air valve 4 are fixedly connected to one side of the elevated base 6 and the hot channel 3, respectively. The outer surfaces of the main body 1, the cold channel 10, the hot channel 3 and the elevated base 6 are all covered with a first insulation cotton 19. The outer surfaces of the thermostat 20 and the water pump speed controller 21 are all covered with a second insulation cotton 27. In winter, the first insulation cotton 19 is covered on the outer surface to keep it warm and prevent problems such as frostbite caused by excessively low temperature.

[0020] Specific implementation steps: When the ambient temperature is low in winter, fresh air from outside is a good cooling medium. At this time, the outlet air valve 4 and return air valve 5 are opened, and the coil fan 7 is turned on. Low-temperature fresh air from outside is introduced through a downdraft. The fresh air enters the cabinet through the cold aisle 10. The cast aluminum heating plate 2 simulates the heating process of the server 18 inside the main cabinet 1. The axial flow fan 9 introduces fresh air from the cold aisle 10, performing forced convection heat exchange on the cast aluminum heating plate 2. The hot air blown out from the main cabinet 1 exits through the hot aisle 3 and exits through the return air valve 5. This mode is... In the air-cooled mode, when the ambient temperature is high in summer, cooling water is introduced into the inner tube 8 of the rack's work panel. The high-temperature outside air first exchanges heat with the cooling water at the inner tube 8. The cooled fresh air enters the rack through the cold aisle 10. The cast aluminum heating plate 2 simulates the heating process of the server 18 inside the rack. The axial fan 9 introduces fresh air into the cold aisle 10 to perform forced convection heat exchange on the cast aluminum heating plate 2. The hot air blown out from the rack body 1 is sent out through the hot aisle 3 and the air outlet valve 4. This mode is a composite heat dissipation mode that combines air cooling and water cooling.
