Description

Technical Field

[0001] This utility model belongs to the field of computer room heat dissipation technology, specifically relating to a computer room atomizing evaporative cooling energy-saving device. Background Technology

[0002] Communication equipment (such as servers and switches) operates under high load year-round. Traditional air conditioning needs to maintain temperature and humidity throughout the year, resulting in electricity consumption accounting for 40%-60% of the total energy consumption of the equipment room. In transitional seasons (such as spring and autumn) or in low-temperature areas, air conditioning cannot effectively utilize natural cooling sources, resulting in energy waste. On the other hand, cooling through atomized evaporative cooling equipment has inaccurate humidity control, which can easily lead to condensation or static electricity buildup on the equipment. Condensation in the equipment room can cause serious damage to the equipment, ranging from corrosion and shortened lifespan to direct damage or short circuits, affecting the normal operation of the equipment room and data security. Utility Model Content

[0003] To overcome the challenges of high-load operation of communication equipment rooms year-round, traditional air conditioners require continuous cooling to maintain temperature and humidity. However, during transitional seasons (such as spring and autumn) or in low-temperature regions, air conditioners cannot effectively utilize natural cooling sources, resulting in energy waste. Furthermore, cooling methods using atomized evaporative cooling equipment suffer from inaccurate humidity control, easily leading to condensation or static electricity buildup on equipment. This invention provides an energy-saving atomized evaporative cooling device for equipment rooms. When outdoor temperatures are low, a water curtain machine utilizes natural outdoor cooling to cool the equipment room. In other months, water curtains can be used for spraying water to cool the room. Combining natural outdoor cooling with water curtain spraying achieves energy savings and reduced consumption in the equipment room. Through the cooperation of indoor and outdoor temperature and humidity sensors and a controller, the temperature and humidity in the equipment room are monitored and adjusted in real time to prevent condensation or static electricity buildup on equipment. The filter unit dehumidifies the air entering the equipment room and can be replaced periodically to ensure its filtration effect. The controller integrates an enthalpy comparison unit and a calculation unit, facilitating automated control and management.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A data center atomizing evaporative cooling energy-saving device mainly includes a water curtain machine, a conveying pipe, an air box, an air inlet pipe, an air intake fan, a filter unit, a negative pressure exhaust fan, an indoor temperature and humidity sensor, an outdoor temperature and humidity sensor, and a controller. A partition is provided at the end of the data center, and the water curtain machine is installed inside the partition. A support is provided on the side wall of the data center, and the conveying pipe is detachably installed on the support and sealed to the top of the water curtain machine via a flange. The air box is installed inside the data center, with the top of the air inlet pipe connected to the conveying pipe and the bottom end penetrating the side wall of the data center and communicating with the air box. The air box is connected to the water curtain machine via a delivery pipe and an air inlet pipe. A condensate collection tank is provided at the bottom of the air box. The air inlet fan is installed on the air box. The air box has a cavity structure inside. The filter unit that controls the humidity of the machine room is installed inside the air box. The negative pressure exhaust fan is installed on the side wall at the bottom of the machine room and is connected to the inside of the machine room. The indoor temperature and humidity sensor is installed inside the machine room. The outdoor temperature and humidity sensor is installed on the side wall of the compartment. The controller is installed in the compartment and integrates an enthalpy comparison unit and a dew point calculation unit. The water curtain machine, air inlet fan, negative pressure exhaust fan, indoor temperature and humidity sensor, outdoor temperature and humidity sensor and controller are electrically connected.

[0005] The filter unit includes filter cotton, a multi-layer corrugated fiber composite, and an activated carbon adsorption layer. The filter cotton, the multi-layer corrugated fiber composite, and the activated carbon adsorption layer are installed inside the air box. The corrugated fiber composite, which is used to intercept unevaporated water mist and accelerate airflow diffusion, is formed by wave-shaped stacking of hydrophobic fiber materials, with an interlayer gap of 0.5-2mm.

[0006] An air valve is installed on the air inlet pipe.

[0007] The condensate collection tank is equipped with a level gauge inside and a drain pipe at one end. The drain pipe extends outside the machine room and is fitted with a drain valve. The level gauge, drain valve, and controller are electrically connected.

[0008] The indoor temperature and humidity sensor used for zoned humidity monitoring and preventing local condensation includes at least three sets, which are respectively installed on the top, middle and near the heat dissipation vents of the equipment in the computer room.

[0009] The beneficial effects of this utility model are: When outdoor temperatures are low, the computer room is cooled using natural outdoor cooling sources via water curtain machines. In other months, cooling can be achieved by spraying water through the water curtains. Combining natural outdoor cooling sources with water curtain cooling achieves energy conservation and consumption reduction in the computer room. Through the cooperation of indoor and outdoor temperature and humidity sensors and controllers, the temperature and humidity in the computer room are monitored and adjusted in real time to prevent condensation or static electricity buildup on the equipment, thereby protecting the equipment from damage. The condensate collection tank at the bottom of the air box can collect condensate to prevent water droplets from damaging the equipment, while ensuring a dry environment in the computer room and further preventing condensation. The filter unit can dehumidify the air entering the computer room and can be replaced regularly to ensure its filtration effect. The controller integrates an enthalpy comparison unit and a calculation unit, which facilitates automated control and management. Attached Figure Description

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0020] This utility model discloses an energy-saving atomizing evaporative cooling device for computer rooms. The device mainly includes a water curtain machine 1, a delivery pipe 2, an air box 3, an air inlet pipe 4, an air intake fan 5, a filter unit 6, a negative pressure exhaust fan 7, an indoor temperature and humidity sensor 8, an outdoor temperature and humidity sensor 9, and a controller 10. A partition 111 is provided at one end of the computer room 11. The water curtain machine 1 is installed inside the partition 111. A bracket 12 is provided on the side wall of the computer room 11. The delivery pipe 2 is detachably installed on the bracket 12 and sealed to the top of the water curtain machine 1 via a flange. The air box 3 is installed inside the computer room 11. The top of the air inlet pipe 4 is connected to the delivery pipe 2, and the bottom end penetrates the side wall of the computer room 11 and communicates with the air box 3. 3 is connected to the water curtain machine 1 through the conveying pipe 2 and the air inlet pipe 4. The bottom of the air box 3 is provided with a condensate collection tank 31. The air inlet fan 5 is installed on the air box 3. The air box 3 is set with a cavity structure. The filter unit 6 for controlling the humidity of the machine room 11 is installed inside the air box 3. The negative pressure exhaust fan 7 is installed on the side wall at the bottom of the machine room 11 and is connected to the inside of the machine room 11. The indoor temperature and humidity sensor 8 is installed inside the machine room 11. The outdoor temperature and humidity sensor 9 is installed on the side wall of the compartment 111. The controller 10 is installed in the compartment 111 and integrates an enthalpy comparison unit and a dew point calculation unit. The water curtain machine 1, the air inlet fan 5, the negative pressure exhaust fan 7, the indoor temperature and humidity sensor 8, the outdoor temperature and humidity sensor 9 and the controller 10 are electrically connected.

[0021] like Figure 8 , Figure 9 As shown, the filter unit 6 includes filter cotton 61, multi-layer corrugated fiber composite 62, and activated carbon adsorption layer 63. The filter cotton 61, multi-layer corrugated fiber composite 62, and activated carbon adsorption layer 63 are installed inside the air box 3. The corrugated fiber composite 62, which is used to intercept unevaporated water mist and accelerate airflow diffusion, is formed by wave-shaped stacking of hydrophobic fiber material with a gap of 0.5-2mm between layers. Before entering the machine room 11, the air passes through the filter unit 6 in the air box 3. The filter cotton 61 first intercepts larger particles and some unevaporated water mist. The multi-layer corrugated fiber composite 62, which is formed by wave-shaped stacking of hydrophobic fiber material with a gap of 0.5-2mm between layers, can further intercept unevaporated water mist and accelerate airflow diffusion, making the cold air entering the machine room 11 more evenly distributed. The activated carbon adsorption layer 63 adsorbs odors and harmful gases in the air, ensuring the air quality in the machine room 11.

[0022] like Figure 4 As shown, an air valve 41 is installed on the air inlet pipe 4 to control the air flow in the pipe and meet the air volume requirements of different areas.

[0023] like Figure 8 , Figure 9As shown, a level gauge 311 is installed inside the condensate collection tank 31, and a drain pipe 13 is installed at the end. The drain pipe 13 extends out of the machine room 11, and a drain valve 131 is installed on the drain pipe 13. The level gauge 311, the drain valve 131 and the controller 10 are electrically connected. The condensate collection tank 31 collects the condensate generated during the refrigeration process. The level gauge 311 monitors the water level inside the condensate collection tank 31. When the condensate reaches the preset water level, the controller 10 controls the drain valve 131 to open, and the condensate is discharged out of the machine room 11 through the drain pipe 13.

[0024] The indoor temperature and humidity sensor 8 used for zoned humidity monitoring and prevention of local condensation includes at least three sets, which are respectively installed on the top, middle and near the heat dissipation vents of the equipment in the computer room 11; it can monitor the temperature and humidity in the computer room 11 in zones, detect local temperature and humidity abnormalities in a timely manner, and avoid local condensation.

[0025] Work process: Indoor temperature and humidity sensor 8 and outdoor temperature and humidity sensor 9 transmit the collected data to controller 10 installed in compartment 11. Controller 10 integrates an enthalpy comparison unit and a dew point calculation unit, and analyzes the indoor and outdoor temperature and humidity data to determine whether the cooling equipment needs to be started. When controller 10 determines that the cooling equipment needs to be started based on the analysis results, it sends a start command to water curtain machine 1. Water curtain machine 1 starts working, generating atomized water vapor, which is transported through delivery pipe 2. The air intake fan 5 is installed on the air box 3 and starts under the control of controller 10. The air intake fan 5 draws the cold air generated by the water curtain machine 1 into the air box 3 through the delivery pipe 2 and the air intake pipe 4. An air valve 41 is installed on the air intake pipe 4. The controller 10 can adjust the opening of the air valve 41 according to actual needs, controlling the flow rate of cold air entering the air box 3. Before entering the machine room 11, the air first passes through the filter unit 6 inside the air box 3. The filter cotton 61 in the filter unit 6 intercepts larger particles and some unevaporated water mist, initially purifying the air. The multi-layer corrugated fiber composite 62 is made of hydrophobic fiber material stacked in a corrugated pattern, with an interlayer gap of 0.5 mm. The 2mm thick filter further intercepts unevaporated water mist and accelerates airflow diffusion, making the distribution of cold air entering the computer room 11 more uniform. The activated carbon adsorption layer 63 adsorbs odors and harmful gases in the air, ensuring air quality in the computer room 11. After being filtered and purified by the filter unit 6, the cold air is sent into the computer room 11 from the air box 3 under the action of the intake fan 5 to cool the computer room 11. The negative pressure exhaust fan 7, installed on the bottom side wall of the computer room 11, is started under the control of the controller 10 and connected to the inside of the computer room 11. The negative pressure exhaust fan 7 extracts the hot air in the computer room 11, forming an air circulation, accelerating the air circulation in the computer room 11, and improving the cooling effect. The bottom of the air box 3 is equipped with a condensate collection tank 31. The condensate generated during the cooling process will flow into the condensate collection tank 31. A level gauge 311 is installed inside the condensate collection tank 31. The level gauge 311 will monitor the condensate level in real time and transmit the data to the controller 10. When the level reaches a certain height, the controller 10 will control the drain valve 131 installed on the drain pipe 13 to open and discharge the condensate to the outside of the machine room 11 through the drain pipe 13. When the humidity in a certain area of ​​the machine room 11 is detected to reach the set threshold, the atomization intensity of the water curtain machine 1 corresponding to that area will be automatically reduced and the exhaust rate of the negative pressure exhaust fan 7 will be increased to avoid local condensation.

[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
