Description

COOLING APPARATUS AND ITS METHOD OF INTERNET DATA CENTER

The present invention relates to a cooling technique of a data center, and more particularly, to compare the temperature and humidity of the air inside and the outside air of the data center, thereby introducing outside air or circulating the inside air, thereby reducing the inside of the data center. A cooling device in a data center suitable for cooling and a method thereof.

The present invention is derived from a study conducted as part of the IT growth engine technology development project of the Ministry of Knowledge Economy [Task Management No .: 2007-S-016-03, Title: Development of a low-cost large-scale global Internet service solution].

As is well known, equipment enclosures or racks that house electronic equipment such as data processing, networking and telecommunications equipment may be used in facility rooms and large data centers (IDCs) as well as in small distribution rooms. Used to store and arrange equipment, although an enclosure may be included when referring to a rack, the appliance rack may be in an open configuration or may be housed within a rack enclosure.

Various standards have been developed to allow equipment manufacturers to design rack mountable equipment that can mount standard racks manufactured by various manufacturers. Multiple units of the same electronic equipment may be mounted and include a front mounting rail stacked vertically within the rack. For example, an industrial standard rack can have a height of about 6 to 6.5 feet, a width of about 24 inches, and a depth of about 40 inches, such a rack is generally referred to as a "19 inch" rack, and the Electronics Industries As defined by the Association's EIA-310-D standard.

Here, 19-inch racks are used in a variety of data centers and other large installations, and as the Internet spreads, data centers (IDCs) including hundreds of racks are being installed, computer equipment and in particular computer servers and blades. As the size of the blades decreased, the number of electronic equipment mounted in each rack increased, and interest in properly cooling the equipment increased.

In particular, heat generated by rack-mounted equipment can adversely affect the performance, stability and service life of the equipment components, which are housed within the enclosure while the rack-mounted equipment is in operation. It may be vulnerable to hot spots and heat build-up formed.

In addition, the amount of heat generated by the rack of equipment depends on the amount of power consumed by the equipment in the rack during operation, and users of electrical equipment add rack-mounted components as their needs change and new needs arise, Can be removed and rearranged.

On the other hand, the data center (IDC) is generally a fixed unit disposed around the periphery of the data center room, and is provided in a hard piped computer room air conditioner (CRAC) unit. This CRAC unit draws air from the front of the unit and discharges the cooled air upward through the ceiling of the data center room.

On the other hand, the CRAC unit is implemented by sucking air near the ceiling of the data center room and discharging the cooled air down the raised floor to be delivered to the front of the equipment rack, which is at room temperature (approximately Intake air at 72 ° F) and discharge cooled air (approximately 55 ° F), blow it into the data center room and mix it with room temperature air near the equipment rack or near the equipment rack.

In general, rack-mounted equipment cools itself by drawing air along the front or air inlet side of the rack and substantially evacuating air from the outlet side or back of the rack.

The disadvantage of this CRAC type air conditioning system is that cold air is inefficient because it is mixed with air at room temperature. Ideally, as high as possible air is drawn into the CRAC unit, and the outlet air formed by the CRAC is above room temperature to make the system as efficient as possible and to reduce energy and floor space as much as possible. It may be several degrees or less. In addition, airflow requirements can vary considerably with varying numbers and types of rack-mounted components and various configurations of racks and enclosures.

Especially for large data centers that require CRAC units in the middle or center of a data center room or near the middle or center of a data center room, the possibility of piping joints is possible. Since it is not desirable to secure the coolant piping to the ceiling of the data center because of the risks associated with defects, the delivery of coolant to the CRAC unit must be located within the platform.

In addition, in a typical CRAC system, the piping of the unit requires significant cutting and hand soldering of the pipes, which is common, and leaks of water or coolant in the data center may be used in equipment racks. Can cause a risk of damage, and the likelihood of an earthquake vibrates pipes and can lead to joint failure. For at least these reasons, many data center designers and operators are reluctant to consider data center cooling plumbing overhead.

On the other hand, analysis of data center energy usage shows that the IT system takes up approximately 50% of the energy consumption and the cooling system takes up approximately 37% of the energy consumption. To ensure a path, it is desirable to remove as much heat from the equipment as possible with minimal energy, and rack configurations and air conditioner placement must be optimized to optimize air flow.

However, in the past, most data centers (IDC) have a rack arranged so that the cool air flows through the front of the rack and hot air is discharged through the rear of the rack. Aisle) and cold aisle are formed, and techniques are being studied to operate the thermohygrostat more effectively because hot air flows into the thermohygrostat.

Accordingly, the present invention prevents the mixing of cold and hot air in the data center, discharges hot air out of the data center, and introduces cold outside air into the data center, thereby efficiently using data with relatively little energy. It is an object of the present invention to provide a cooling device of a data center and a cooling method thereof.

Referring to FIG. 6, in the standby mode of the cooling device installed in the data center (step 602), in the thermo-hygrostat main body 302 of the thermo-hygrostat 300, the server rack 100 disposed so that each rear part faces each other in the data center. The internal temperature and the internal humidity for the hot air in between are sensed, and the external temperature and the external humidity for the air outside the data center are sensed (step 604).

In addition, the thermo-hygrostat main body 302 calculates a difference between the sensed external temperature and the external humidity and the sensed internal temperature and the internal humidity, and accordingly, whether the external temperature and the external humidity have a relatively larger value than the internal temperature and the internal humidity. Check (step 606).

As a result of the check in step 606, when the external temperature and the external humidity have a value that is relatively smaller than the internal temperature and the internal humidity, the thermo-hygrostat main body 302 adjusts the intake and exhaust duct 200 of the server rack 100.

In addition, the thermo-hygrostat main body 302 adjusts the intake and exhaust damper to intake and filter the outside air of the data center through the intake filter box 304, and maintains the function of the data center by using the intake and filtered outside air. Cooling and humidity are maintained to maintain a predetermined range value, which is an optimum temperature range value and an optimal humidity range value, and thus the cooled and humidified air is discharged into the data center through the exhaust diffuser 306 (step 610). Here, the exhaust diffuser 306 may use a diffuser manufactured in, for example, a floor grille form, a ceiling plenum box form, or the like, and the floor grille exhaust diffuser 306 may be a server rack disposed inside a data center. It is installed at the bottom of the front portion of the 100 to exhaust the cooled and humidified air from the thermo-hygrostat 300, the exhaust diffuser 306 in the form of a ceiling plenum box is an exhaust duct 206 of the intake and exhaust duct 200 Cooled and humidified air from the thermo-hygrostat 300 may be discharged through the blower duct 306b / 1 and the blower diffuser 306b / 2 connected to the ceiling.
