Description

Technical Field

[0001] This application relates to the field of host equipment cooling technology, and more specifically, to a system for improving the cooling efficiency of outdoor host equipment under extreme weather conditions. Background Technology

[0002] With the continuous development of technology, various host devices are widely used in many fields such as industrial production and data centers; these host devices generate a lot of heat during operation, and their normal operation has certain requirements for temperature environment.

[0003] In extreme high-temperature weather conditions, the outdoor host unit of the main unit located outdoors cannot effectively dissipate heat; natural air cooling is extremely inefficient in high-temperature environments because the temperature difference between the air and the host unit becomes smaller due to the high ambient temperature, making it difficult to dissipate heat; after the temperature drops to the freezing point, traditional water cooling systems are easily frozen and are not convenient to unclog.

[0004] Simple cooling measures are insufficient to meet the precise temperature control requirements of host equipment under extreme high temperatures, and may result in insufficient or excessive cooling. This can not only affect the performance of the host equipment, such as slowing down the computing and processing speed and delaying data transmission, but may also damage the precision components inside the host equipment due to factors such as temperature stress, shorten its service life, increase the cost of equipment maintenance and replacement, and affect the normal production and operation of related industries.

[0005] Therefore, this application proposes a cooling and efficiency improvement system for outdoor main unit equipment under extreme weather conditions to solve the aforementioned problems. Utility Model Content

[0006] To address the aforementioned issues, this application provides a system for improving the cooling efficiency of outdoor main unit equipment under extreme weather conditions.

[0007] This application provides a cooling and efficiency improvement system for outdoor main unit equipment under extreme weather conditions, which adopts the following technical solution:

[0008] A system for improving the cooling efficiency of outdoor main unit equipment under extreme weather conditions includes:

[0009] Control box (1), wherein a control module (2) is provided inside the control box (1);

[0010] The PLC control center (3) is electrically connected to an outdoor temperature sensor (4), and the control module (2) is electrically connected to the PLC control center (3).

[0011] Pipe (5), the flow direction of the pipe (5) is connected in series with a first electric valve (6), and the end of the flow direction of the pipe (5) is connected in parallel with an atomizing nozzle (7), the spray direction of the atomizing nozzle (7) is located at the fins of the outdoor unit condenser of the main unit equipment.

[0012] Furthermore, a second electric valve is connected in parallel to the pipeline, and the second electric valve is located between the first electric valve and the atomizing nozzle in the communication path; the second electric valve is electrically connected to the control module.

[0013] The above technical solution effectively addresses low-temperature environments. When the outdoor temperature drops below 10°C, the control module can close the first electric valve and open the second electric valve to drain the water from the spray cooling system's pipes. This design prevents water from freezing in low-temperature environments, avoiding problems such as pipe rupture and nozzle damage caused by water expansion due to freezing. This ensures the safety and reliability of the entire cooling system in low-temperature seasons or cold regions, reduces equipment failure maintenance costs and downtime caused by freezing damage, ensures stable system operation in different seasons, extends system lifespan, and reduces operational risks.

[0014] Furthermore, the electrical control connection cable between the control module and the PLC control center is of model RVVP and specification 2×1.0.

[0015] The above technical solutions ensure the stability and anti-interference of control signal transmission. The shielded RVVP cable effectively prevents external electromagnetic interference from affecting the control signal, ensuring accurate signal transmission between the control module and the PLC control center. This allows the entire cooling system to accurately adjust its operation based on real-time data from the outdoor temperature sensor, avoiding cooling system malfunctions or misoperations caused by signal transmission errors or instability. This improves the safety and reliability of system operation and ensures the continuous and stable operation of the main equipment under extreme weather conditions.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] The PLC control center works in conjunction with the outdoor temperature sensor to intelligently control the operation of the cooling system based on different outdoor temperature conditions. In high temperatures, the system uses atomizing nozzles to spray water for cooling, effectively removing heat from the condenser fins of the outdoor unit of the main equipment, ensuring stable operation of the main equipment in extreme high-temperature weather, and avoiding performance degradation or failure due to high temperatures.

[0023] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0024] This application discloses a system for improving the cooling efficiency of outdoor main unit equipment under extreme weather conditions, including:

[0025] Control box 1, and control module 2 is installed inside control box 1;

[0026] PLC control center 3 is electrically connected to outdoor temperature sensor 4, and control module 2 is electrically connected to PLC control center 3.

[0027] Pipe 5 is connected in series with a first electric valve 6 in the flow direction of pipe 5, and an atomizing nozzle 7 is connected in parallel at the end of the flow direction of pipe 5. The spray direction of the atomizing nozzle 7 is located at the fins of the outdoor unit condenser of the main unit equipment.

[0028] See Figure 1 A second electric valve 8 is connected in parallel to pipe 5, located between the first electric valve 6 and the atomizing nozzle 7. The second electric valve 8 is electrically connected to the control module 2, effectively coping with low-temperature environments. When the outdoor temperature is below 10℃, the control module 2 can control the closure of the first electric valve 6 and the opening of the second electric valve 8, thereby draining the water from pipe 5 of the spray cooling system. This design prevents water from freezing in low-temperature environments, avoiding problems such as pipe 5 rupture and nozzle damage caused by water freezing and expansion. This ensures the safety and reliability of the entire cooling system in low-temperature seasons or cold regions, reduces equipment failure maintenance costs and downtime caused by freezing damage, ensures stable system operation in different seasons, extends system lifespan, and reduces operational risks.

[0029] See Figure 1 The electrical connection cable between control module 2 and PLC control center 3 is RVVP, with a specification of 2×1.0. It ensures the stability and anti-interference of control signal transmission. The shielded RVVP cable can effectively prevent the influence of external electromagnetic interference on the control signal, ensuring accurate signal transmission between control module 2 and PLC control center. This allows the entire cooling system to accurately adjust and operate based on the real-time data of outdoor temperature sensor 4, avoiding cooling system failures or malfunctions caused by signal transmission errors or instability. This improves the safety and reliability of system operation and ensures the continuous and stable operation of the main equipment under extreme weather conditions.

[0030] The control logic of the above-mentioned outdoor host equipment cooling and efficiency improvement system under extreme weather conditions includes the following steps:

[0031] S1. When the outdoor equipment platform temperature exceeds the set maximum temperature (e.g., 37℃) and the main compressor starts, the first electric valve is opened, and clean water or other cooling medium flows in the pipeline and eventually flows to the atomizing nozzle to spray the cooling medium onto the fins.

[0032] S2. When the outdoor equipment platform temperature is lower than the set normal temperature (e.g., 35℃) or the main unit is turned off, the first electric valve is closed, thereby turning off the spray cooling system.

[0033] When the outdoor temperature is below the minimum temperature (e.g., 10℃), the S3 valve closes the first electric valve and opens the second electric valve, thereby draining the water in the spray cooling system pipes to prevent the pipes from freezing due to a continuous drop in temperature.

[0034] In the initial state, the second electric valve in this application is normally closed and will only be opened in step S3.

[0035] The implementation principle of the outdoor host equipment cooling and efficiency improvement system under extreme weather conditions in this application embodiment is as follows:

[0036] Outdoor temperature sensor 4 continuously monitors the outdoor temperature and transmits the temperature data to the PLC control center in real time.

[0037] When the outdoor temperature reaches or exceeds the high temperature set threshold, the PLC control center sends a command to the control module 2. The control module 2 controls the first electric valve 6 to open, so that the cooling medium (such as water) in the pipe 5 begins to flow. After the medium reaches the atomizing nozzle 7 at the end of the pipe 5, it is atomized and sprayed onto the fins of the outdoor unit condenser of the main unit, using the principle of vaporization heat absorption to reduce the temperature of the main unit.

[0038] When the outdoor temperature is below 10℃, the PLC control center sends a command to the control module 2 again. The control module 2 closes the first electric valve 6 and opens the second electric valve 8. The water in the pipe 5 is discharged through the second electric valve 8 under the action of gravity or other auxiliary means (such as compressed air purging, which can be determined according to the actual design), thereby emptying the pipe 5 and preventing the water from freezing.

[0039] Throughout the process, control module 2 and the PLC control center maintain stable signal transmission via an RVVP 2×1.0 electrical control cable to ensure that each component operates accurately according to instructions and to guarantee the normal operation of the system under different temperature environments.

[0040] 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.
