Technical Field
[0001] This utility model relates to the field of computer room technology, and in particular to a water-cooled cooling device for a smart computer room. Background Technology
[0002] With the rapid development of the internet age, the demand for data centers across various industries continues to grow. Statistics show that my country adds approximately 8 million square meters of data center space and 30,000 new data centers annually in recent years. Against this backdrop, the application of energy-saving technologies is receiving increasing attention, encompassing various aspects such as power system energy efficiency analysis, energy-saving control of power and environmental systems, intelligent management of IT equipment, promotion of new energy-saving technologies, and the widespread application of intelligent operation and maintenance software.
[0003] For example, a Chinese utility model patent with publication number CN218473697U discloses an energy-saving data center chilled water cooling device. "This energy-saving data center chilled water cooling device, through the setting of a water cooling mechanism, allows the alarm to sound when the alarm and temperature sensor are connected by telecommunications. At this time, the water pump is started, and the water pump drives the first water pipe to circulate the chilled water in the cooling unit into the inlet pipe. The inlet pipe is then split into two second water pipes through an upper branch pipe. The two second water pipes connect to the outlet pipe through a lower branch pipe, returning to the cooling unit for further cooling." However, this water cooling method has significant hidden dangers: when the surface temperature of the cold surface is lower than the dew point temperature of the air in the data center, condensation is easily generated on the inner wall of the distribution cabinet or the surface of the equipment. The accumulation of water vapor may lead to a decrease in electrical insulation performance, causing short circuits, equipment failures, or even safety accidents. Utility Model Content
[0004] The purpose of this utility model is to provide a water-cooled cooling device for a smart computer room in order to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A water-cooled cooling device for a smart data center includes a data center body. Several sets of power distribution cabinets are arranged side by side inside the data center body. Each set of power distribution cabinets has a cavity on both sides. A heat-conducting metal plate is fixedly connected to the side of the cavity closest to the power distribution cabinet. A serpentine cooling water pipe is fixed to the heat-conducting metal plate by several clamps. Cooling water flows from bottom to top in the serpentine cooling water pipe. An axial flow fan is fixedly installed on the bottom side of the power distribution cabinet near the cavity. Several air holes are opened at the bottom of the power distribution cabinet.
[0006] As a further description of the above technical solution: The computer room is equipped with a cooler and a variable frequency water pump. The outlet of the variable frequency water pump is fixedly connected to an inlet pipe. The first inlet of the variable frequency water pump is fixedly connected to the outlet of the cooler. The inlet of the cooler is fixedly connected to an outlet pipe. The inlets at the bottom of each group of serpentine cooling water pipes are connected to the inlet pipe, and the outlets at the top of each group of serpentine cooling water pipes are connected to the outlet pipe.
[0007] As a further description of the above technical solution: An exhaust fan is fixedly installed on the top of the power distribution cabinet.
[0008] As a further description of the above technical solution: A temperature sensor is fixedly installed on the top of the distribution cabinet, and the temperature sensor is electrically connected to the axial flow fan, exhaust fan, variable frequency water pump and cooling machine.
[0009] As a further description of the above technical solution: An alarm that is electrically connected to a temperature sensor is fixedly installed on the top of the distribution cabinet.
[0010] As a further description of the above technical solution: An anti-condensation heater and a dew point sensor electrically connected to it are fixedly installed on the bottom back of the power distribution cabinet.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, firstly, each distribution cabinet is provided with a cavity on both sides to form a cooling layer, which completely isolates water, moisture and electrical components, avoiding safety hazards such as condensation, short circuit and corrosion caused by temperature difference. Secondly, a dew point sensor and an anti-condensation heater are configured to achieve active anti-condensation, fundamentally preventing accidents such as short circuit and insulation failure caused by water vapor.
[0012] 2. In this utility model, on the one hand, the heat exchange area is increased and the heat conduction efficiency is improved by designing a heat-conducting metal plate and a serpentine cooling pipe. On the other hand, the combination of an axial flow fan and an exhaust fan forms a forced convection air duct, which eliminates local hot spots, resulting in high heat dissipation efficiency and uniform temperature distribution.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-3 This utility model provides a technical solution: a water-cooled cooling device for a smart data center, including a data center body 1, which houses all equipment and provides a closed operating environment; several sets of power distribution cabinets 2 are arranged side by side inside the data center body 1, housing power and IT equipment and serving as the main heat dissipation unit; each set of power distribution cabinets 2 has a cavity 201 on both sides, forming a cooling interlayer, completely isolating water, moisture and electrical components, avoiding safety hazards such as condensation, short circuits, and corrosion caused by temperature differences; a heat-conducting metal plate 14 (such as an aluminum plate or copper plate) is fixedly connected to the side of the cavity 201 near the power distribution cabinet 2, closely adhering to the cabinet wall, efficiently conducting heat, transferring heat from inside the cabinet to the cooling system, and enhancing heat transfer efficiency; several... The clamp 15 fixes the serpentine cooling water pipe 13, which serves as a cooling medium flow channel and absorbs heat. The main body 1 of the machine room is equipped with a cooler 12 and a variable frequency water pump 11. The cooler 12 provides low-temperature cooling water to achieve circulating cooling, and the variable frequency water pump 11 adjusts the water flow to achieve on-demand cooling. The outlet end of the variable frequency water pump 11 is fixedly connected to the inlet pipe 9. The first inlet end of the variable frequency water pump 11 is fixedly connected to the outlet end of the cooler 12. The inlet end of the cooler 12 is fixedly connected to the outlet pipe 10. The inlets at the bottom of each group of serpentine cooling water pipes 13 are connected to the inlet pipe 9, and the outlets at the top of each group of serpentine cooling water pipes 13 are connected to the outlet pipe 10, forming a cooling water circulation network.
[0017] Specifically, such as Figure 1 and Figure 2 As shown, an axial flow fan 3 is fixedly installed on the bottom side of the distribution cabinet 2 near the clamping cavity 201, facing the inside of the cabinet, to force airflow and promote the transfer of hot air to the cooling wall; an exhaust fan 7 is fixedly installed on the top of the distribution cabinet 2 to extract hot air and enhance convection circulation; several air holes 202 are opened at the bottom of the distribution cabinet 2 to serve as inlets for fresh cold air and form a complete air duct.
[0018] Specifically, such as Figure 1 As shown, a temperature sensor 8 is fixedly installed on the top of the distribution cabinet 2 to monitor the air temperature inside the cabinet in real time and control it in conjunction with the control. The temperature sensor 8 is electrically connected to the axial flow fan 3, the exhaust fan 7, the variable frequency water pump 11 and the cooler 12.
[0019] Specifically, such as Figure 1 As shown, an alarm 6, which is electrically connected to the temperature sensor 8, is fixedly installed on the top of the power distribution cabinet 2. When the high temperature exceeds the limit, an audible and visual alarm is triggered to indicate the risk.
[0020] Specifically, such as Figure 1 As shown, an anti-condensation heater 4 and a dew point sensor 5 electrically connected to the bottom of the back of the distribution cabinet 2 are fixedly installed. The anti-condensation heater 4 prevents condensation on the low-temperature surface, and the dew point sensor 5 monitors the temperature and humidity in real time, calculates the air dew point, and prevents condensation from occurring.
[0021] Working principle: In use, firstly, the temperature sensor 8 monitors the air temperature inside the distribution cabinet 2 in real time. When the temperature rises to the preset threshold (e.g., 40℃), the control system starts the axial flow fan 3 to force the air inside the cabinet to circulate. The hot air is blown towards the heat-conducting metal plate 14 in the two side cavities 201. The heat is conducted to the serpentine cooling water pipe 13 through the metal plate. If the temperature continues to rise to a higher threshold (e.g., 48℃), the control system starts the variable frequency water pump 11 and the cooler 12. The cooling water flows out from the cooler 12 and is distributed to each group of serpentine cooling water pipes 13 through the inlet pipe 9. After absorbing the heat transferred by the heat-conducting metal plate 14, the hot water returns to the cooler 12 through the outlet pipe 10 to cool down again, forming a closed loop. The variable frequency water pump 11 can automatically adjust the flow rate according to the temperature difference to avoid over-cooling. Secondly, the axial flow fan 3 draws in cold air from the bottom air hole 202 and blows it toward the heat-generating equipment. The hot air rises and is drawn out by the top exhaust fan 7, forming a forced convection circulation of "bottom air intake and top air exhaust", which significantly improves heat dissipation efficiency. Meanwhile, the dew point sensor 5 collects the temperature and humidity inside the cabinet in real time and calculates the air dew point temperature. When the surface temperature of the heat-conducting metal plate 14 is detected to be close to or lower than the dew point temperature, the anti-condensation heater 4 is automatically activated to slightly increase the local temperature and prevent water vapor condensation. The anti-condensation heater 4 is controlled in coordination with the water cooling system to avoid the risk of condensation caused by "overcooling and local overcooling". Finally, if the temperature continues to rise to a dangerous level (such as 55°C), alarm 6 will be activated, emitting an audible and visual alarm to alert maintenance personnel to handle the situation promptly.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
