Description

Server rack

The present invention relates to a server rack, and more particularly, to configure the server rack in a sealed structure to block the inflow of dust and to always control the inside of the server rack with a dual control function by cooling control of the refrigerant cycle device and heating control of the heating device. The present invention relates to a server rack having a constant temperature / humidity function controlled at a constant temperature, an emergency protection function against heat generation due to abnormal high temperatures, and a fire detection and extinguishing function.

Generally, a rack refers to an international standard (IEC) box for mounting network equipment and computing equipment including a server, and is mainly a rack mount method that is stacked on a floor to configure and store computing equipment such as a server or a hub. It is called as server rack / hub rack / communication rack / network system rack / CCTV rack / multi rack according to the computer equipment to be installed.It is called as 19 inch rack / 21 inch rack according to the external size of the computer equipment.

Also, depending on the functions provided, closed racks (dust ingress blocking racks), earthquake-resistant racks (racks with anti-vibration protection against earthquakes), and EMP racks (electromagnetic pulses, the ability to block the inflow of nuclear weapons from nuclear weapons) ) Rack, EMC shielding rack (a rack having a function of blocking the noise of electronic equipment so as not to affect the operation of other electronic devices), EMI shielding rack (rack with electromagnetic shielding), vibration-free rack ( It is also called a rack having a function to prevent external physical shaking for ship and vehicle mounting). The present invention collectively referred to as the various racks described above as a server rack.

Servers and computer equipment mounted in the server rack may have fatal consequences such as system stoppage or failure if the heat load is not removed due to high integration and high performance.

The general cooling method of the heating load is to form a separate computer room and blow the cooling air through the air conditioning unit inside the server rack to remove the heat load.If the computer room cannot be operated separately due to cost, space, etc. A fan for blowing is provided inside the rack, and is configured to cope with the heat load.

However, if the computer room for the server rack is operated separately, there is no blocking method for the inflow of dust because the cooling air through the air conditioning unit must be supplied internally, and the connection cable of various information processing devices and the heat island phenomenon in the computer room In order to solve the imbalance of temperature control, the back of the server rack is often opened, so it is not possible to prepare for the inflow of dust.

On the other hand, in a cabinet in which various information processing apparatuses, such as a server, are installed, when the information processing apparatus is mounted, a blower fan that can be mounted therein is miniaturized to reduce space, and thus the heat generation is not smoothly removed, and the heat generation is not smoothly removed. In this case, a fatal damage of the server or the information processing apparatus is brought, resulting in an economic loss and a loss of data information that cannot be recovered.

As such, one of the major reasons for the failure of the server and the information processing apparatus in the server rack is a problem caused by overload due to the failure of temperature control, and to solve this problem, as described above, a computer room for removing heat generation inside the server rack ( It is common to operate a server room.

However, the computer room in which the server rack is installed supplies air for removing heat loads inside the computer room by centralized cooling to control the temperature inside the room, and the server rack in the computer room has a perforated plate on the side for smooth air supply to the inside. It will be used for sufficient ventilation.

Therefore, in order to remove the heat generation in the server rack, the heat generation of the entire interior of the computer room must also be removed, which has the disadvantage of very high energy loss.

In addition, there is a structure that does not supply sufficient air volume to the highly integrated server and recirculates the heat, which can not sufficiently eliminate the heat load inside the server rack, and incurs excessive cost investment and management manpower costs for the operation and management of the computer room. .

In addition, the server rack in the computer room as well as the server rack of the basic method requires a temperature management structure to increase the ventilation area by using a perforated plate for the internal heat exchange, and to introduce and discharge forcedly cooled air into the interior.

Therefore, the constant temperature / humidity management can be managed separately by the computer room due to the supply / exhaust method, but problems such as static electricity caused by fine dust flowing into the server rack, short circuit, spark, malfunction of the equipment, hard disk error, etc. Is very disadvantageous for the operation and management of the computer room. Below we look at the prior art related to the server rack.

And the suction fan 42 and the blower chamber 6 for supplying the internal air cooled by the evaporator 43 again into the rack (1) on the opposite side of the suction port 41 is installed.

The blowing chamber (6) is; It is installed to form a partition between the rack box (1) and the internal air circulation duct (4) and to form a blower 61 to one side is coupled to the discharge duct (7) mounted inside the rack box (1). That is, the supply chamber 6 is coupled to the upper portion of the inner air circulation duct 4 (lower portion of the rack box 1) so that the rack box 1 and the inner air circulation duct 4 are isolated from each other, and one side air passage 61. Is coupled to the inlet 71 of the discharge duct (7) mounted inside the rack box 1 by the suction fan 42, the discharge holes (11, 11 ') and the discharge duct 12 of the rack box (1) Cool the internal air sucked through the evaporator (43) or by the heater (5) to be sent to the discharge duct (7) inside the rack (1) to blow and circulate through the discharge holes (72, 72 ') .

The heating control by the heater 5 enables dual control of cooling / heating together with the cooling control by the evaporator 43. The configuration of the heater 5 and the like will be described later.

[Revision 16.10.2015 under Rule 91]
The blower chamber 6 forms a blower 61 on one side to couple the discharge duct 7 to the blower 61.

The discharge duct 7 forms discharge

holes

72 and 72 'and is installed on one side of the rack box 1 (opposite side of the discharge holes 11 and 11'), and a lower inlet 71 is formed in the blowing chamber. (6) is coupled to communicate with the upper portion of the air passage (61).

The discharge holes 72 and 72 'of the discharge duct 7 are evenly distributed over the entire surface of the rack box 1 at regular intervals up and down as shown in the illustrated example so that the discharge holes 72 and 72' can be evenly blown and circulated inside the rack box 1. Form to be placed.

In addition, the discharge holes (11, 11 ') provided on the opposite side of the discharge duct 7 also rack box (1) at regular intervals up and down so that the internal air evenly sucked into the internal air circulation duct (1) It is formed evenly over the other side of the () (opposite side of the discharge duct 7).

The blowing chamber 6 provided between the rack box 1 and the internal air circulation duct 4 as described above has the suction holes 43 and the discharge holes 11 and 11 ′, the discharge duct 12, and the suction port 41. The internal air sucked through the evaporator 43 and the heater 5 is blown to the discharge duct 7 through the air blower 61 to be racked through the discharge holes 72 and 72 '. 1) Circulate inside.

[Revision 16.10.2015 under Rule 91]
In the above, the heater 5 is installed under the blowing chamber 6 so that the internal air sucked by the suction fan 42 is heated before being blown through the discharge duct 7 so that the heater 5 is supplied into the rack box 1 so as to supply the inside of the rack box 1. (1) In order to maintain a constant temperature inside, the heater 5 is installed between the evaporator 43 of the internal air circulation duct 4 and the blowing chamber 6, or as shown in FIG. 7) The heater 5A may be provided inside so that the heater 5A can be heated before the wind and circulation inside the rack box 1.

[Revision 16.10.2015 under Rule 91]
Then, the external air circulation duct 8 opposite the partition 31 of the constant temperature and humidity module 3 in which the internal air circulation duct 4 is installed is recovered from the evaporator 43 of the internal air circulation duct 4. The condenser 82 and the cooling fan 83 are installed to exchange heat of the internal air with the external air to be discharged to the outside. Hereinafter, the external air circulation duct 8 will be described in detail with reference to FIGS. 9 to 12.

[Revision 16.10.2015 under Rule 91]
The external air circulation duct 8 includes a compressor 81 for supplying and circulating refrigerant to the evaporator 43, a condenser 82, a cooling fan 83, and an inlet port 84 for introducing external air. To form.

A discharge port 85 is formed on the opposite side of the inlet port 84, that is, the cooling fan 83 is installed to discharge the heat radiated from the condenser 82 by the cooling fan 83, and the discharge port ( 85 is connected to the discharge duct (86).

[Revision 16.10.2015 under Rule 91]
The external air circulation duct 8 is operated separately from the internal air circulation duct 4 to radiate the condensation heat of the internal air condensed by the evaporator 43 by introducing and circulating the external air.

On the other hand, the discharge duct 86 is formed in the discharge hole 87, the discharge hole 87 is to be discharged to the outside of the room through the exhaust hood 88 communicated to the outside.

The exhaust hood 88 may not be required in a room having external air ventilation, such as a general office. However, in an airtight space of a room in which the server rack 10 is installed, heated air is released due to heat dissipation. Since it causes the temperature inside the room to rise, it is preferable to discharge it immediately through the exhaust hood 88 (see FIGS. 11 and 12).

[Revision 16.10.2015 under Rule 91]
According to the present invention, the air inside the rack box 1 is discharged through the blower 61 through the air passage 61 in which the internal air cooled / heated by the evaporator 43 and the

heaters

5 and 5A of the internal air circulation duct 4. And blows into the rack box 1 through the discharge holes 72 and 72 'of the discharge duct 7.

The present invention maintains constant temperature without temperature deviation by appropriately combining cooling and heating with PID control (Proportional-Integral-Derivative Control) by cooling and heating.

In the general refrigerant cycle as shown in FIG. 7, when the internal air is out of the set temperature (elevated) and reaches the compressor operating temperature, the compressor starts operation and the refrigerant cycle proceeds. As the refrigerant cycle proceeds, the internal air is out of the set temperature. When the maximum cooling temperature is reached, the compressor stops operating, thereby stopping the refrigerant cycle.

When the refrigerant cycle is stopped and the temperature gradually rises due to the internal heat generation, the temperature is gradually set out of the set temperature and the compressor operation temperature is reached again.

Such a general refrigerant cycle control method has a problem that it is difficult to maintain a constant temperature in a state where the temperature variation is small because there is always a concern that there is always a large temperature deviation as well as a sudden drop of the temperature, that is, quenching.

In other words, if the internal temperature is low while the internal temperature is low and the temperature decrease is rapidly cooled and continued (only the compressor is stopped), the internal temperature can be raised to the set temperature to maintain the constant temperature (the forced rise. Since there is no means, it is difficult to maintain a constant temperature.

However, the present invention not only prevents overheating above the set temperature by the refrigerant cycle, but also prevents overheating below the set temperature by installing the

heaters

5 and 5A, thereby providing an advantage of constant temperature keeping with very low temperature deviation. do.

In other words, when the internal air is out of the set temperature (raises) and reaches the compressor operating temperature, the compressor 81 starts to operate and the refrigerant cycle proceeds. When the compressor 81 stops operation, the

heater

5, 5A is started and the heated internal air flows into the rack box 1 and circulates so that the inside of the rack box 1 falls to the maximum cooling temperature. At the same time, it maintains the optimum temperature at all times.

Referring again to this, the

heaters

5 and 5A which prevent the subcooling below the set temperature by operating the

heaters

5 and 5A while the compressor 81 is stopped and the

heaters

5 and 5A which have achieved the objective of falling to the maximum cooling temperature are also Shutting down causes a rise in temperature due to internal heat generation.

When the temperature rises to the set temperature, the compressor 81 operates again to cool and circulate the internal air, while the internal air is cooled and circulated, so that the heater 5 is not subcooled below the set temperature again. 5A) is repeatedly operated to maintain the inside of the rack (1) at a constant temperature.

Therefore, the repetition and the progress by the dual control of the cooling / heating become a steady state after a predetermined time, and thus the temperature deviation is almost eliminated, so that the constant temperature can be maintained efficiently. (See Figure 7)

On the other hand, as an example that can be compared with the above embodiment, it is possible to consider a case where the inverter can be controlled and operated by installing an inverter together with the general refrigerant cycle.

In other words, the compressor 81 may be controlled by an inverter according to the heating load of the computing equipment mounted inside the rack box 1 to control the inside of the rack box 1 to a constant temperature.

However, in the inverter control method, as shown in FIG. 8, the controller operates the compressor 81 in consideration of internal heat generation and minimizes the temperature deviation by adjusting the capacity of the refrigeration cycle. In this case, the above supercooling may be prevented. Not only is there a lack of a method, but the additional configuration of the inverter increases the volume of the server rack 10 and causes a price increase, and thus it can be seen that it is reasonable compared to the dual control method of the cooling / heating of the present invention. .

13 to 24 are views for explaining an emergency protection device of the present invention will be described with reference to this emergency protection device.

The emergency protection device of the present invention, when the constant temperature and humidity module (3) does not operate due to power failure, other causes, open the exhaust damper (40) in case of emergency, such as the case of abnormal high temperature above the set temperature inside the rack box (1) By forcibly discharging the high temperature air inside the rack box (1) to the outside, by introducing the outside air into the rack box (1) through the intake damper (70) to operate the computer equipment (S) inside the rack box (1) without a problem. Configure emergency protection to ensure that

The exhaust damper 40 is preferably installed above the rack (1) to facilitate the discharge of the hot air in the rack (1) to the outside, the intake damper (70) flows outside air into the rack (1) It is preferable to install under the rack (1) so that the ventilation, cooling of the rack (1) discharged through the exhaust damper 40 can be made.

The exhaust damper 40 forms an exhaust duct 410 on the rack box 1 and installs the exhaust cover 50 in the exhaust duct 410 to open and close.

The exhaust cover 50 is installed to couple the bracket 530 to the rack box 1 in which the exhaust duct 410 is formed, and to open and close the exhaust cover 50 by the damper motor 510 on the bracket 530.
