Technical Field

[0001] This application relates to the technical field of power distribution rooms, and in particular to an automatic cooling system for power distribution rooms. Background Technology

[0002] As the scale of the power system continues to expand, the power distribution room, as the core node of power distribution, has its internal power equipment (such as transformers, switchgear, capacitor banks, etc.) operating under high load for a long time, continuously generating a large amount of heat.

[0003] Traditional power distribution room cooling systems mostly rely on fixed cold air delivery devices, which deliver air evenly into the room through pre-installed ventilation ducts or wall-mounted air conditioning units.

[0004] However, due to the complex layout of equipment and uneven distribution of heat sources in the power distribution room, the cold air cannot accurately cool the heat sources. This technology has revealed significant defects in practical applications, which seriously restricts heat dissipation efficiency and equipment safety. Utility Model Content

[0005] To improve the efficiency of cooling in computer rooms, this application provides an automatic cooling system for power distribution rooms.

[0006] This application provides an automatic cooling system for a power distribution room, which adopts the following technical solution: An automatic cooling system for a power distribution room includes a computer room, in which power distribution cabinets are arranged. An air conditioner is installed on the outer wall of the computer room, and a cooling pipe is installed at the output end of the air conditioner. A main duct is installed on the inner ceiling of the computer room, and multiple branch ducts are installed on the side wall of the main duct. Air inlets are opened on the bottom wall of the multiple branch ducts. The cooling pipe extends into the computer room and is connected to the main duct.

[0007] By adopting the above technical solution, when the air conditioner is started, the cold air first flows from the cold air pipe into the main pipe, and then flows from the main pipe into multiple branch pipes. Then it is ejected from the air outlets of the branch pipes. At this time, the cold air cools the power distribution cabinets arranged in multiple locations, which helps to improve the cooling efficiency of the computer room.

[0008] Optionally, the air inlet is provided with louvers, and the louvers are provided with a fixing component for connecting to the main flow pipe.

[0009] By adopting the above technical solution, the louvers are fixedly installed at the air inlet using a fixing component. Under the action of the louvers, it is beneficial to control the flow direction of cold air and improve the stability of the cooling of the power distribution cabinet.

[0010] Optionally, the fixing component includes a screw, and the end corner of the louver is provided with a connecting lug. The screw passes through the connecting lug and is threadedly connected to the diverter pipe.

[0011] By adopting the above technical solution, when it is necessary to fix the louvers, firstly, the louvers are covered on the air inlet, and then the connecting lugs are connected to the splitter pipe threadedly by screws. At this time, the louvers are fixed to the air inlet, which helps to improve the stability of louver assembly and disassembly.

[0012] Optionally, the fixing component includes a retaining strip disposed on the top surface of the louver and engaging with the air vent.

[0013] By adopting the above technical solution, when it is necessary to fix the louvers, first align the louvers with the air inlet, and then press the louvers towards the air inlet. At this time, the retaining strip is engaged with the wall of the air inlet, and the louvers are fixed to the air inlet, which helps to improve the stability of louver assembly and disassembly.

[0014] Optionally, multiple branch pipes are connected to an electronic valve at one end near the main pipe, and a control panel is provided on the outer wall of the machine room, the control panel being electrically connected to the electronic valve.

[0015] By adopting the above technical solution, the opening and closing of the electronic valve is controlled by the control panel, thereby controlling the flow state of the diversion pipe, which is beneficial to cooling the corresponding power distribution cabinet and thus improving the applicability of the cooling system.

[0016] Optionally, a connecting frame is provided between two adjacent rows of the power distribution cabinets, and the connecting frame is equipped with a temperature sensor, which is electrically connected to the control panel.

[0017] By adopting the above technical solution, the temperature between two adjacent rows of distribution cabinets is detected by a temperature sensor and the temperature value is displayed on the control panel, which improves the convenience of observing the temperature between two adjacent rows of distribution cabinets.

[0018] Optionally, the walls of the computer room are equipped with exhaust fans, which are electrically connected to the control panel.

[0019] By adopting the above technical solution, the exhaust fan can be activated through the control panel to circulate the air in the computer room, thereby improving the stability of the external airflow circulation in the computer room.

[0020] Optionally, the outer wall of the computer room is provided with a support frame, and the air conditioner is installed on the top surface of the support frame.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] See Figure 1 and Figure 2 An automatic cooling system for a power distribution room includes a computer room 1, in which power distribution cabinets 2 are installed. The power distribution cabinets 2 are arranged in multiple rows in a straight line. Air conditioners 3 are installed on the outer wall of the computer room 1. In this embodiment, the air conditioners 3 are environmentally friendly air conditioners. The number of air conditioners 3 is selected based on the area of ​​the computer room 1. In practical applications, a medium-sized factory of 200-300 square meters requires 2-3 environmentally friendly air conditioners with a capacity of 40,000 cubic meters per hour.

[0027] A main duct 4 is fixedly installed on the ceiling of the machine room 1, with both ends of the main duct 4 being closed. Multiple branch ducts 5 are fixedly connected to the side walls of the main duct 4, with each branch duct 5 having a closed end away from the main duct 4. Each branch duct 5 is located between two adjacent rows of distribution cabinets 2, and each branch duct 5 has air inlets 6 arranged in a straight line on its bottom wall. A cooling pipe 7 is fixedly connected to the output end of the air conditioner 3, with the end of the cooling pipe 7 away from the air conditioner 3 extending into the machine room 1, and this end being fixedly connected to the side wall of the main duct 4.

[0028] When the power distribution cabinet 2 is working for a long time, it is easy to generate heat. As the temperature of the computer room 1 increases, it can accelerate the lifespan of aging electronic components. Therefore, when it is necessary to lower the temperature of the computer room 1, the air conditioner 3 is turned on. The cold air flows into the main pipe 4 through the air pipe 7, and then is distributed into multiple branch pipes 5, and finally sprayed out from the air outlet 6. At this time, the cold air blows onto the power distribution cabinet 2 with the shortest distance, thereby cooling the power distribution cabinet 2 and ultimately lowering the temperature in the computer room 1.

[0029] See Figure 2 To facilitate the guidance of cold air, the air outlet 6 is detached and installed with louvers 8. Louvers 8 are also equipped with fixing components, which fix louvers 8 to the air outlet 6.

[0030] Example 1: See Figure 2 and Figure 3 The fixing component includes screws 9, and connecting ears 10 are fixedly connected to the corners of the louvers 8. The number of screws 9 is the same as the number of connecting ears 10. The fixing end of the screw 9 passes through the connecting ear 10 and is threadedly connected to the diversion pipe 5.

[0031] When it is necessary to fix the louver 8, first align the louver 8 with the air inlet 6, and then insert the louver 8 into the air inlet 6. At this time, the connecting lug 10 abuts against the bottom wall of the diversion pipe 5. Next, pass the screw 9 through the connecting lug 10 and tighten the screw 9 at the same time. At this time, the louver 8 is fixed to the air inlet 6, and the installation of the louver 8 is completed. Under the airflow guiding effect of the louver 8, it is beneficial to ensure that the cold air blows towards the distribution cabinet 2.

[0032] Example 2 differs from Example 1 in that the structure of the fixing component is different: join Figure 4 The fixing component includes a retaining strip 11, the vertical cross-section of which is hook-shaped. There are four retaining strips 11, which are fixed to the top surface of the louver 8 in a rectangular array. The retaining strips 11 are plastic and are engaged with the wall of the air inlet 6.

[0033] When it is necessary to fix the louver 8, first align the louver 8 with the air inlet 6, and then insert the louver 8 into the air inlet 6. At this time, the retaining strip 11 is engaged with the air inlet 6, and the louver 8 is fixed in the air inlet 6, thus completing the installation of the louver 8.

[0034] See Figure 2 To facilitate control of the flow state of the multi-flow pipes, multiple branch pipes 5 are respectively fixedly connected to electronic valves 12 at their ends near the main flow pipe 4. A control panel 13 is fixedly installed on the outer wall of the machine room 1. The control panel 13 is a touch screen electronic panel in this field and has Internet of Things (IoT) functionality. The control panel 13 is electrically connected to multiple electronic valves 12 and also electrically connected to the air conditioner 3.

[0035] It is worth mentioning that, see Figure 5 A connecting frame 14 is fixedly connected between two adjacent rows of power distribution cabinets 2. A temperature sensor 15 is fixedly installed on the connecting frame 14, and the temperature sensor 15 is electrically connected to the control panel 13.

[0036] Temperature sensor 15 is used to detect the temperature between two adjacent rows of distribution cabinets 2 and transmit the temperature value to the control panel 13. When the temperature of a row is too high, the electronic valve 12 of that row is activated via the control panel 13, allowing the flow pipe 5 of that row to circulate. Cool air is then blown towards the distribution cabinet 2 of that row through the louvers 8, thereby reducing the temperature of the distribution cabinet 2.

[0037] See Figure 1 An exhaust fan 16 is fixedly installed on the side wall of the computer room 1. The exhaust fan 16 allows air to circulate inside and outside the computer room 1, thereby enabling the air in the computer room 1 to be circulated externally, which helps to remove the heat inside the computer room 1 to the outside of the computer room 1.

[0038] See Figure 1 The outer wall of the machine room 1 is fixedly connected with support frames 17, and the number of support frames 17 is the same as the number of air conditioners 3. The air conditioners 3 are fixedly installed on the top surface of the support frames 17.

[0039] The air conditioner 3 is fixed by the support frame 17, which improves the stability of the air conditioner 3 installed on the outer wall of the computer room 1.

[0040] Working principle of an automatic cooling system for a power distribution room: When the power distribution cabinet 2 operates for a long time, it easily generates heat. As the temperature in the computer room 1 increases, it can accelerate the lifespan of aging electronic components. Therefore, when it is necessary to cool down all the power distribution cabinets 2 in the computer room 1, the air conditioner 3 is started through the control panel 13, and all electronic valves 12 are opened. The cold air flows into the main pipe 4 through the air pipe 7, and then is distributed into multiple branch pipes 5, and finally sprayed out from the air outlet 6. At this time, the cold air blows onto the power distribution cabinet 2 with the shortest distance, thereby cooling down the power distribution cabinet 2 and ultimately reducing the temperature in the computer room 1.

[0041] In summary, the cooling air cools the power distribution cabinets 2 arranged in multiple locations, thereby improving the cooling efficiency of the computer room 1.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
