[0003] In Korea, the size of the data industry is growing every year, and with the recent rise of AI, cloud, big data, and mobile services, the size of the data industry is expected to grow even further.
[0004] In the case of the above big data, a hardware foundation called a data center is essential, and the data center can be said to be the core infrastructure for storing and distributing big data.
[0005] In the case of major domestic corporations, including Naver, Kakao, and Hana Financial Group, there are approximately 150 data centers, and the number is expected to increase further when including those scheduled for completion in the future.
[0006] Meanwhile, given the nature of data centers, which must operate continuously, earthquakes or fires are fatal factors that can lead to downtime.
[0007] In fact, there was an incident where some services were interrupted due to a fire at Kakao's data center, and each data center is investing heavily to protect data from earthquakes and fires.
[0008] The present invention is intended to solve the above-described problem, and provides an internal temperature control system for a data center that can quickly extinguish a fire by operating a temperature control device when a fire occurs inside a data center, and can prevent thermal runaway and fire by constantly checking the internal temperature of the data center, comparing it with a preset temperature, and cooling a server having a high temperature.
[0009] However, the purpose of the present invention is not limited to the purpose mentioned above, and other purposes not mentioned will be clearly understood by those skilled in the art from the description below.
[0010] In order to achieve the above purpose, the present invention provides a system for controlling the internal temperature of a data center (20) in which a plurality of servers (10) are arranged, the system comprising: a temperature control device for resolving overheating or fire of servers (10) caused by heat generated within the data center (20); and a control unit for comparing the internal temperature with a preset temperature and operating the temperature control device according to the result of the comparison.
[0011] In addition, the temperature control device comprises a temperature sensor (410) for measuring the temperature inside the data center, a spray nozzle (370) for spraying a working liquid according to a control signal of the control unit, a supply pipe (350) for supplying the working liquid to the spray nozzle (370), and a chamber (310) for storing the working liquid to be supplied to the supply pipe (350). The working liquid has insulating properties, so that even if the server is sprayed while it is in operation, the server does not stop operating or a short circuit occurs.
[0012] In addition, the floor on which the servers are placed is provided with a discharge pipe (120) for discharging the sprayed working liquid to the outside when the working liquid is sprayed through the spray nozzle (370), and the floor on which the servers are placed is characterized by a guide space (110) for guiding the sprayed working liquid to the discharge pipe (120).
[0013] In addition, a pump (320) and a valve (330) for supplying the working liquid to the spray nozzle are included between the spray nozzle (370) and the chamber (310), so that the working liquid is supplied to the spray nozzle, and the control unit is characterized in that it determines whether to use the working liquid as a fire extinguishing liquid or a cooling liquid depending on the value input from the temperature sensor (410).
[0014] In addition, since the operation of the pump (320) is driven in three stages of upper, middle, and lower, when the working liquid is used for extinguishing, the pump is operated in the upper stage where the working liquid is sprayed the most, and when the working liquid is used for cooling, the pump is operated in the middle stage where the working liquid is sprayed the middle stage or the lower stage where the working liquid is sprayed the least.
[0015] The features and advantages of the present invention will become more apparent from the following detailed description based on the attached drawings.

[0027] In addition, since the working liquid has insulating properties, the server does not stop operating or cause a short circuit even if it is sprayed while the server is in operation.
[0028] In addition, the above-mentioned working liquid is characterized by an insulating breakdown electric field of 100 to 200 kV / cm, a computerized value of 0.02 mgKOH / g or less, a flash point of 50°C or higher, an initial boiling point of 175°C to 195°C, an end point of 200°C to 220°C, a surface tension of 30 dyne / cm2 or less, an aniline point of 90°C or less, and a density of 0.8 g / cm3 or less at 15°C.
[0029] Meanwhile, on the floor where the above servers are placed, a discharge pipe (120) is provided to discharge the sprayed working liquid to the outside when the sprayed working liquid is sprayed through the spray nozzle (370).
[0030] Additionally, an induction space (110) is provided on the floor where the above servers are placed to guide the sprayed working liquid to the discharge pipe (120).
[0031] In addition, the above-mentioned servers are provided with a plate (150) and a support (151) installed under the plate (150) to support the floor, so that an induction space (110) can be formed between the server and the floor.
[0032] In addition, a pump (320) and a valve (330) for supplying the working liquid to the spray nozzle are included between the spray nozzle (370) and the chamber (310), so that the working liquid is supplied to the spray nozzle.
[0033] In addition, the control unit determines whether to use the working liquid as a extinguishing liquid function or a cooling liquid function based on the value input from the temperature sensor (410).

[0037] In addition, when the temperature input value is 60℃ to 80℃, the control unit operates the pump in the intermediate stage to supply the working liquid through the supply pipe to the injection nozzle (370) and spray it onto the server, thereby cooling the temperature of the overheated server.
[0038] In addition, when the temperature input value input from the temperature sensor (410) to the control unit is 80°C or higher, the control unit operates the pump (320) to the upper stage to supply the working liquid to the injection nozzle (370) through the supply pipe (350) and spray it onto the server, thereby cooling the temperature of the overheated server or extinguishing a fire.
[0039] In addition, the control unit can measure the temperature change over time according to the temperature input value of the temperature sensor (410), measure the time for the temperature to rise from t1 to t2 multiple times, list them in order of the shortest time, and control to spray more working fluid as the time gets shorter.
[0040] In addition, the above t1 is 40℃ and the above t2 is 60℃, and after measuring multiple times and listing them in order of shortest time, the pump (320) is operated at medium level for up to the top 50%, and the pump (320) is operated at low level for 51% or less, thereby enabling rapid control of the temperature inside the data center.
