Abstract
Description
Technical Field
[0001] This utility model relates to the field of computer room heat dissipation technology, and in particular to a computer room heat dissipation system. Background Technology
[0002] Natural gas is rapidly developing as an important clean energy source, and the number of natural gas compressor rooms is growing rapidly along with the construction of long-distance pipelines. As the power driver in the natural gas transportation system, the stability and reliability of the compressor's operation are extremely important. During normal operation, it is necessary to dissipate heat from the natural gas compressor room in a timely manner to ensure that the temperature inside the unit remains constant within a certain range.
[0003] Normally, natural gas compressor rooms are cooled primarily by using rooftop explosion-proof fans for forced exhaust, combined with natural or axial flow fans for mechanical air supply. However, during periods of extreme summer heat, conventional methods are insufficient to effectively remove the heat generated by the compressors and the ambient radiation from the room. The temperature inside the room can easily exceed the compressors' optimal operating temperature, potentially causing some compressors to malfunction and shut down, thus affecting the normal supply of natural gas.
[0004] Therefore, there is an urgent need for a computer room cooling system to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a computer room cooling system that can reduce the temperature inside the computer room under various different external ambient temperatures, ensuring that the computer room is at a suitable working temperature.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A data center cooling system is provided, comprising:
[0008] A ventilation device, comprising an exhaust fan, a supply fan, and a supply duct, wherein the exhaust fan is located inside the machine room, the air inlet of the supply duct is located outside the machine room, the air outlet is located inside the machine room, and the supply fan is located at the air inlet.
[0009] An atomizing device, comprising a water storage tank, a water supply pipe, a water pump, and an atomizing nozzle, wherein the atomizing nozzle is disposed within the air supply pipe and located at the rear end of the air supply fan, the water supply pipe is connected to the water storage tank and the atomizing nozzle, and the water pump is connected to the water supply pipe.
[0010] The control device includes a first temperature and humidity sensor and a controller. The first temperature and humidity sensor is located in the computer room, and the controller is signal-connected to the first temperature and humidity sensor, the ventilation device, and the atomizing device.
[0011] As an optional solution for the computer room heat dissipation system, the air supply duct is equipped with a water collection tank, which is located at the rear end of the atomizing nozzle.
[0012] As an optional solution for the computer room heat dissipation system, the water collection tank is equipped with a water seal structure.
[0013] As an optional solution for the computer room cooling system, the atomizing device also includes a filter, which is connected inside the water supply pipe and located at the rear end of the water pump.
[0014] As an optional solution for the computer room cooling system, the atomizing device also includes an atomizing pump, which is connected to the water supply pipe and located at the rear end of the filter.
[0015] As an optional solution for the computer room cooling system, the water storage tank includes a float valve, which is located at the water inlet of the water storage tank.
[0016] As an optional solution for the computer room heat dissipation system, the ventilation device includes multiple exhaust fans, which are evenly arranged in the computer room.
[0017] As an optional solution for the computer room cooling system, the air supply duct is provided with multiple air outlets, which are evenly distributed within the computer room.
[0018] As an optional solution for the computer room heat dissipation system, the control device also includes a second temperature and humidity sensor, which is installed in the air supply duct and located between the air supply fan and the atomizing nozzle. The second temperature and humidity sensor is signal-connected to the controller.
[0019] As an optional solution for the computer room cooling system, the control device also includes a third temperature and humidity sensor, which is installed in the air supply duct and located at the rear end of the atomizing nozzle. The third temperature and humidity sensor is signal-connected to the controller.
[0020] The beneficial effects of this utility model are:
[0021] This invention provides a computer room cooling system. A first temperature and humidity sensor detects the temperature and humidity inside the computer room and feeds them back to the controller. When the controller receives a temperature reading that the temperature inside the computer room has reached a preset threshold, it activates the exhaust fan and the supply fan. The supply fan blows air into the computer room, while the exhaust fan expels the air from the computer room to the outside for cooling. If the temperature inside the computer room does not decrease, the controller activates a water pump to transport cooling water from a storage tank to the air supply duct through a water supply pipe. The cooling water is atomized by atomizing nozzles, allowing heat exchange between the air in the air supply duct and the atomized cooling water as the air is blown into the air supply duct. This humidified and cooled air then enters the computer room, improving the cooling effect. This computer room cooling system, through the cooperation of ventilation and atomization devices, cools and humidifies the air entering the computer room when the temperature is high, increases air circulation, and improves the cooling effect. Furthermore, the control device monitors and automatically activates the cooling system, ensuring the stable operation of the equipment inside the computer room. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0032] like Figure 1 As shown, the computer room cooling system of this embodiment includes a ventilation device 100 and a control device 400. The ventilation device 100 includes an exhaust fan 110, a supply fan 120, and a supply duct 130. The exhaust fan 110 is installed inside the computer room 200 and is used to exhaust the air inside the computer room 200 to the outside of the computer room 200, thereby increasing the air flow speed inside the computer room 200 and realizing air circulation inside and outside the computer room 200. The air inlet 131 of the supply duct 130 is installed outside the computer room 200, and the air outlet 132 is installed inside the computer room 200. The supply fan 120 is installed at the air inlet 131 and blows the air outside the computer room 200 into the computer room 200 through the supply duct 130, thereby realizing air circulation inside and outside the computer room 200.
[0033] The control device 400 includes a first temperature and humidity sensor 410 and a controller 420. The first temperature and humidity sensor 410 is installed in the computer room 200 and is used to measure the temperature and humidity in the computer room 200 in real time. The controller 420 is connected to the first temperature and humidity sensor 410 and the ventilation device 100. The first temperature and humidity sensor 410 feeds back the temperature and humidity data to the controller 420, realizing real-time monitoring of the temperature and humidity in the computer room 200. The controller 420 is connected to the exhaust fan 110 and the supply fan 120 and can control the opening and closing of the exhaust fan 110 and the supply fan 120.
[0034] When the temperature data fed back by the first temperature and humidity sensor 410 is lower than the preset threshold of the controller 420, the temperature and humidity in the computer room 200 are normal, and the exhaust fan 110 and the supply fan 120 are in the off state. When the temperature data fed back by the first temperature and humidity sensor 410 is higher than the preset threshold of the controller 420, it is determined that the temperature in the computer room 200 is high. At this time, the controller 420 can control the exhaust fan 110 and the supply fan 120 to start, and force mechanical ventilation to cool down the computer room 200, thereby controlling the temperature in the computer room 200 and ensuring the normal operation of the equipment.
[0035] Optionally, the computer room cooling system includes multiple exhaust fans 110, which are evenly arranged within the computer room 200 to ensure uniform airflow within the computer room 200. For example, the number of exhaust fans 110 can be three, four, six, etc., and can be evenly arranged in a single row or matrix pattern depending on the size of the computer room 200.
[0036] Optionally, the air supply duct 130 is provided with multiple air outlets 132, which are evenly distributed within the computer room 200, so that the air flowing into the computer room from the outside can flow evenly within the computer room. For example, three, four, six, etc., air outlets 132 can be provided.
[0037] In this embodiment, the controller 420 is set as a PLC controller. The PLC controller can store and execute control programs and control various types of mechanical equipment or production processes through digital or analog inputs and outputs. Through the real-time detection of the control device 400, the heat dissipation system can be automatically turned on to ensure the stable operation of the equipment in the machine room 200.
[0038] When the computer room 200 is in a high-temperature environment during summer, due to the limited effectiveness of air cooling, the temperature inside the computer room 200 cannot be reduced after the exhaust fan 110 and the supply fan 120 have been turned on for a period of time. The first temperature and humidity sensor 410 detects that the temperature inside the computer room 200 is continuously higher than the preset threshold of the controller 420. Therefore, further heat dissipation is required inside the computer room 200. The computer room heat dissipation system provided in this embodiment also includes an atomizing device 300. The atomizing device 300 includes a water storage tank 310, a water supply pipe 320, a water pump 330, and an atomizing nozzle 340. The atomizing nozzle 340 is disposed in the air supply pipe 130 and located at the rear end of the supply fan 120. The water supply pipe 320 is connected to the water storage tank 310 and the atomizing nozzle 340. The water pump 330 is connected to the water supply pipe 320. The controller 420 is signal-connected to the atomizing device 300.
[0039] When the exhaust fan 110 and the supply fan 120 have been turned on for the time preset by the controller 420, and the first temperature and humidity sensor 410 detects that the temperature drop in the computer room 200 is less than the set range of the controller 420, the controller 420 can turn on the water pump 330 to pump the cooling water in the water storage tank 310 to the water supply pipe 320. The cooling water is atomized and released into the air supply pipe 130 through the atomizing nozzle 340, so that the cooling water can exchange heat with the air in the air supply pipe 130 from the supply fan 120. This achieves pre-humidification and cooling of the air in the air supply pipe 130, which improves the heat exchange efficiency of the air in the computer room 200 after it enters the computer room 200. This allows the computer room 200 to cool down quickly when the external environment is high, ensuring the normal operation of the equipment.
[0040] Optionally, the water storage tank 310 includes a float valve 311, which is located at the water inlet of the water storage tank 310. By setting the float valve 311, the water storage tank 310 can be automatically replenished to ensure a continuous supply of cooling water. At the same time, it can automatically stop adding water when the water level reaches a certain level, thus saving water resources.
[0041] Furthermore, the atomizing device 300 also includes a filter 350, which is connected inside the water supply pipe 320 and located at the rear end of the water pump 330. The filter 350 is used to filter large particulate impurities in the water supply pipe 320, preventing impurities from flowing with the cooling water and causing blockage of the atomizing nozzle 340, thereby reducing the frequency of downtime maintenance.
[0042] Furthermore, the atomizing device 300 also includes an atomizing pump 360, which is connected to the water supply pipe 320 and located at the rear end of the filter 350. The atomizing pump 360 enables preliminary atomization of the cooling water within the water supply pipe 320, resulting in more uniform atomization after the cooling water passes through the atomizing nozzle 340 and enters the air supply pipe 130. For example, in this embodiment, the cooling water is atomized into tiny water mists of less than 13 μm, thereby improving the heat exchange efficiency between the cooling water and the air.
[0043] Understandably, the atomizing nozzle 340 is positioned in the opposite direction to the air flow in the air supply duct 130, so that the flow direction of the atomized water is opposite to the flow direction of the air in the air supply duct 130, which makes the heat exchange between the cooling water and the air more complete and improves the utilization rate of the atomized cooling water.
[0044] Furthermore, the air supply duct 130 is also equipped with a water collection tank 133, which is located at the rear end of the atomizing nozzle 340. The water collection tank 133 is used to collect cooling water in the air supply duct 130, preventing cooling water from flowing into the machine room 200 from the air outlet 132. Optionally, the water collection tank 133 is equipped with a water seal structure, which can store a portion of the cooling water to prevent air from flowing out of the water collection tank 133. For example, the water seal structure can be a U-shaped water seal, which is simple in structure and easy to install and maintain.
[0045] Understandably, the water pump 330 and the atomizing pump 360 can be configured as variable frequency pumps, and the working efficiency of the water pump 330 and the atomizing pump 360 can be adjusted through the controller 420 to save energy.
[0046] Furthermore, the control device 400 also includes a second temperature and humidity sensor 430 and a third temperature and humidity sensor 440. The second temperature and humidity sensor 430 is disposed within the air supply duct 130 and located between the air supply fan 120 and the atomizing nozzle 340. The third temperature and humidity sensor 440 is disposed within the air supply duct 130 and located at the rear end of the atomizing nozzle 340. The second temperature and humidity sensor 430 and the third temperature and humidity sensor 440 are respectively connected to the controller 420 via signals. The second temperature and humidity sensor 430 can detect the temperature and humidity of the air blown into the air supply duct 130 by the air supply fan 120, and the third temperature and humidity sensor 440 can measure the temperature and humidity of the air after cooling and humidification. By comparing the data before and after, the operating status of the water pump 330 and the atomizing pump 360 is adjusted to maximize the utilization efficiency of the water pump 330 and the atomizing pump 360.
[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
