Abstract
Description
Technical Field
[0001] This utility model relates to the field of data center hotspot management technology, specifically to a data center structure for achieving local hotspot management. Background Technology
[0002] Equipment in data centers generates significant heat during operation. If this heat cannot be dissipated promptly, it can lead to overheating, impacting normal equipment operation. Localized hotspots are a common temperature issue in data centers, causing slow equipment performance, system crashes, and in severe cases, business interruptions and data loss. Therefore, hotspot management ensures stable operation of equipment within the data center at suitable temperatures, preventing equipment failures due to overheating. Furthermore, hotspot management can improve the energy efficiency of the data center.
[0003] Traditional data center server rooms are prone to localized hotspots primarily due to the following reasons: 1) The airflow from the perforated backplate of a single rack is mismatched with the airflow required by the IT equipment inside, causing the rack temperature to rise; 2) Empty storage spaces within the rack result in heat loss, leading to increased rack temperature; 3) Excessive gaps between adjacent racks in the same row cause cold aisle heat loss, resulting in increased rack temperature; 4) Improper matching between heat load and cooling capacity leads to increased rack temperature; 5) As data center equipment ages, the hot air generated by older, heat-generating equipment within the racks cannot be efficiently expelled, creating eddies within the rack, resulting in high pressure and temperature, forming localized hotspots. These localized hotspots can create a harsh operating environment for the equipment within the rack, leading to equipment damage and ultimately economic losses. Utility Model Content
[0004] This invention provides a data center structure for local hotspot management, thereby solving the technical problems of local hotspots and poor management effects in existing data center technologies.
[0005] To address the aforementioned problems, the data center structure for localized hotspot mitigation provided by this utility model adopts the following technical solution:
[0006] A data center structure for implementing local hotspot management includes:
[0007] A computer room is a room with racks arranged in parallel. Adjacent racks are separated by enclosed cold and hot aisles. The racks include equipment racks containing equipment and empty racks without equipment.
[0008] The outer perimeter of the vacant cabinet is sealed with insulation to reduce heat loss;
[0009] The bottom of the closed cold channel is provided with a first fan for blowing cold air into the equipment cabinet, and the upper part of the hot channel is provided with a second fan for timely extracting heat.
[0010] Temperature sensors are arranged in the closed cold channel and the hot channel to collect real-time temperature.
[0011] The entire machine room structure further comprises a core controller which is signal-connected with the first fan, the second fan and the temperature sensors to adjust the working state of the first fan and the second fan according to the collected temperature of the temperature sensors.
[0012] The data center machine room structure for realizing local hotspot treatment has the advantages that: the idle cabinet is sealed and covered by the thermal insulation member, so that the loss of cold air can be effectively reduced, and local hot spots can be avoided at the idle cabinet; the temperature of the closed cold channel and the hot channel is collected by the temperature sensors, so that the core controller can timely adjust the working of the first fan and the second fan, thereby eliminating local hot spots in time, ensuring that the cold air is in sufficient state, and achieving the purpose of eliminating high temperature in the cabinet and ensuring the safe operation of the equipment; through the above arrangement, the technical problem of local hot spots and poor treatment effect of the existing data center machine room is effectively solved.
[0013] Further, the thermal insulation member is thermal insulation cotton.
[0014] Further, the thermal insulation cotton is 5mm-thick high-density aluminum foil thermal insulation cotton with a B-grade flame retardant level, and is fixed on the outer periphery of the idle cabinet by a cable tie. The thermal insulation cotton has a low thermal conductivity, can effectively reduce the heat transfer, and thus has a good thermal insulation effect; meanwhile, the thermal insulation cotton is soft and will not damage the cabinet, and is easy to disassemble.
[0015] Further, the gap between adjacent equipment cabinets is sealed by a blind plate. The loss of cold air is further reduced.
[0016] Further, the first fan is a cold channel axial flow fan located at the bottom of the closed cold channel and below the ventilation shutter.
[0017] Further, the second fan is a hot channel axial flow fan located at the upper side of the hot channel.
[0018] Further, the core controller is a controller capable of supporting analog input, digital input and output, having a 485 communication interface, and supporting MODBUS RTU protocol and connection with a dynamic system.
[0019] Further, a touch screen connected with the core controller is further included, and the touch screen is used for displaying the local hot spot inlet and outlet air temperature, the local hot spot cold aisle temperature, the fan running state, the high temperature alarm, the fault alarm and the contactor of the fan in real time.

[0027] It should be noted that the main concept of the present application is to improve the empty cabinet 3, the closed cold aisle 4 and the hot aisle 5 to fully retain the cold quantity, eliminate the heat, and avoid the local hot spot at the empty cabinet 3. The temperature of the closed cold aisle 4 and the hot aisle 5 is collected by the temperature sensor 9, which can facilitate the core controller to timely adjust the first fan and the second fan to work, and then timely eliminate the local hot spot, ensure the cold quantity in sufficient state, so as to achieve the purpose of eliminating the high temperature in the cabinet, and ensure the safe operation of the equipment.

[0028] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.
[0029] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0030] An embodiment of the data center structure for local hotspot management provided by this utility model:
[0031] like Figs. 1 to 3 As shown, the data center structure for local hotspot management includes a server room 1 with parallel racks arranged within it. Adjacent racks are separated by enclosed cold aisles 4 and hot aisles 5. The racks include equipment racks 2 containing equipment and empty racks 3 without equipment. The outer perimeter of the empty racks 3 is sealed with insulation to reduce cold loss. A first fan is located at the bottom of the enclosed cold aisle 4 to pump cold air into the equipment racks 2, and a second fan is located at the top of the hot aisle 5 to extract heat promptly. Temperature sensors 9 are installed in both the enclosed cold aisle 4 and hot aisle 5 to collect real-time temperature data. The entire server room structure also includes a core controller, which is signal-connected to the first fan, the second fan, and the temperature sensors 9 to adjust the operating status of the first and second fans based on the temperature collected by the temperature sensors 9.
[0032] First, let's introduce the insulation component. The insulation component is insulation cotton 6. Insulation cotton 6 is 5mm thick high-density aluminum foil insulation cotton with a flame retardant rating of B. It is fixed to the outer perimeter of the unused cabinet 3 using cable ties. The insulation cotton has a low thermal conductivity, effectively reducing heat transfer and achieving good thermal insulation performance. At the same time, the insulation cotton is soft, will not damage the cabinet, and is easy to disassemble. In other embodiments, the thickness of insulation cotton 6 can also be adjusted according to actual needs.
[0033] Meanwhile, the gaps between adjacent equipment cabinets 2 are sealed with blind flanges (not shown in the figure) to further reduce the loss of cold energy.
[0034] Regarding the first and second fans: The first fan is the cold aisle axial flow fan 7, located at the bottom of the enclosed cold aisle 4 and below the ventilation louvers. The second fan is the hot aisle axial flow fan 8, located above the hot aisle 5. Fig. 1 The arrows in the diagram indicate the flow direction of cold and heat, respectively.
[0035] Regarding the core controller: The core controller supports analog inputs and digital inputs / outputs, has a 485 communication interface, and supports the MODBUS RTU protocol for connection to environmental control systems.
[0036] Finally, the whole machine room structure further comprises a touch screen connected with the core controller, and the touch screen is used for displaying the local hot spot inlet and outlet air temperature, the local hot spot cold aisle temperature, the fan running state, the high temperature alarm, the fault alarm and the contactor control of the fan in real time.
[0037] When the whole machine room structure works, referring to Fig. 3 , firstly, temperature collection is carried out, and the cabinet inlet and outlet air temperature is calculated, when the inlet and outlet air temperature difference reaches the start setting value, the hot aisle axial flow fan 8 is started, when the inlet and outlet air temperature difference reaches the stop setting value, the hot aisle axial flow fan 8 is stopped;
[0038] When the cold aisle temperature reaches the start setting value, the cold aisle axial flow fan 7 is started, and when the cold aisle temperature reaches the stop setting value, the cold aisle axial flow fan 7 is stopped.
[0039] In summary, the data center machine room structure for realizing local hot spot treatment has the advantages that: the heat preservation cotton 6 and the blind plate are used to block the cabinet, so that the cold energy in the cold aisle is not lost; the cold aisle axial flow fan 7 is configured, and the cabinet cold energy demand is automatically started and stopped, so that the required cold energy and air volume of the cabinet are ensured, and the safety of the customer server is ensured without adding air conditioners;
[0040] The hanging type axial flow fan is added in the hot aisle 5, and the fan is automatically started and stopped according to the set temperature, so that the local hot spot is eliminated and the hot air backflow is prevented without affecting the customer maintenance channel; all temperature control is set to have a start and stop dead zone, so that the frequent start and stop caused by temperature fluctuation at the edge of the set value is avoided;
[0041] All fans and sensors adopt plug-in connectors, so that the whole system can be quickly deployed to the high temperature point by the general operation and maintenance personnel when the customer equipment changes or the local hot spot changes. The touch screen can set the start and stop temperature, and display the local hot spot temperature and fan running condition in real time, so that the machine room centralized management is facilitated; the core controller has an open communication protocol, and the local hot spot data of the whole machine room can be uploaded to the dynamic environment system to realize remote monitoring.
[0042] According to the above description of the specification, those skilled in the art can also understand that the terms used such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer" and the like indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of the specification, and are only for the purpose of facilitating the description of the scheme of the utility model and simplifying the description, and do not explicitly or implicitly indicate or suggest that the devices or elements involved must have the specific orientation, be constructed and operated in the specific orientation, therefore, the above orientation or positional relationship terms cannot be understood or interpreted as a limitation on the scheme of the utility model.
[0043] Also in the description of the present specification, the meaning of "a plurality of" is at least two, for example, two, three or more, etc., unless explicitly specifically limited otherwise.
