1 to 3, a server room cooling apparatus 100 according to an embodiment of the present invention includes an outside air inflow unit 110, a filter unit 120, an evaporation cooler 130, an eliminator A bypass damper 150, a cooling member 155, a blowing unit 160, a relief damper 170, an exhaust unit 180, and a mixing damper 190.

The server room cooling apparatus 100 using outside air according to an embodiment of the present invention supplies cold outside air to a place where it is necessary to cool the heat such as a data center, The present invention is characterized in that the inside of the Server Room is cooled at a lower cost by using outside air (for example, the outside of the building) at all times throughout the year even under changing environmental conditions. In addition, the server room cooling apparatus 100 using the outside air according to an embodiment of the present invention mixes the outside air directly with hot air generated in the server room, and adjusts the proper temperature. In winter, It is one feature that is possible. Furthermore, the server room cooling apparatus 100 using the outside air according to an embodiment of the present invention may be configured in a modular manner to form the server room cooling apparatus 100, so that the server room cooling apparatus 100 can be easily assembled, And the like.

Here, the data center provided with the server room cooling apparatus 100 using outside air according to an embodiment of the present invention can be manufactured as a container type modular type. Therefore, it is possible to stack the data centers in the form of a plurality of containers in the horizontal / vertical direction according to need, and the expansion can be facilitated.

Hereinafter, this will be described in more detail.

Referring again to FIGS. 1, 2 and 3, the server room cooling apparatus 100 may be divided into a mixing unit 101, a cooling unit 102, a server room 200, and the like by barrier ribs and the like.

The outside air inflow portion 110 is formed at one side of the mixing portion 101 and serves to introduce air outside the server room cooling apparatus 100 into the server room cooling apparatus 100. The outside air inflow portion 110 is provided with a damper to control the opening and closing of the outside air inflow portion 110 to control the amount of outside air introduced through the outside air inflow portion 110. As an example of such a damper, an electric motor or a motorized damper (MD) that is automatically opened and closed by air pressure may be provided.

In addition, the outside-air inlet 110 may further include a pre-filter 111. The prefilter 111 can be installed at the inner side of the outside air inflow part 110 and removes foreign matter such as dust, insects, or leaves in the air. The prefilter 111 is a device for removing foreign matters such as dust, And the like. Such a prefilter 111 is advantageous in that it is small in resistance, high in dust collection efficiency, highly resistant to corrosion, easy to clean, light in weight and easy to handle.

The filter unit 120 is formed between the mixing unit 101 and the cooling unit 102 to filter air moving from the mixing unit 101 to the cooling unit 102. That is, the outside air introduced into the outside air inflow part 110 and the air introduced into the mixing damper 190 are mixed in the mixing part 101 and then moved to the cooling part 102 through the filter part 120. The filter unit 120 may include a mesh (not shown) or the like to remove foreign substances entering the cooling unit 102. In the present embodiment, the filter unit 120 is disposed below the outside air inlet 110 and may be formed in a direction substantially perpendicular to the outside air inlet direction of the outside air inlet 110.

The evaporation cooler 130 may function to cool the air introduced into the cooling unit 102. In detail, the evaporation cooler 130 is provided with a jet nozzle, and water or mist of fine particles is introduced into the outside air introduced through the outside air inflow part 110 so that the temperature and humidity inside the cooling part 102 are maintained in an appropriate state. (Not shown). That is, the evaporation cooler 130 blows mist to the outside air to raise the low humidity characteristic of the outside air and lower the temperature so that air suitable for the equipment operation is supplied into the server room. The evaporation cooler 130 may raise the pressure of the water by the pump and spray the mist through the spray nozzle directly to the outside air passing through the evaporative cooler 130. In this way, the temperature of the outside air can be lowered by about 2 to 4 占 폚 just by spraying the mist directly to the outside air.

The water eliminator 140 allows the non-evaporated water to evaporate one more time and serves to prevent the water particles from scattering to the front equipment. For this purpose, the water removing unit 140 may be formed in such a structure that air can pass through and water particles can be formed. For example, a 3D air mat or the like can be used.

The bypass damper 150 is a damper that can be opened and closed as needed, and functions as a kind of resistance avoiding damper. In detail, the cooling member 155 formed at the lower portion of the bypass damper 150 acts as a resistance against the airflow during a period in which cooling is unnecessary (for example, in the winter), so that the blowing power is unnecessarily required. Therefore, during the period when the cooling member 155 is not used, the blower power can be reduced by opening the bypass damper 150 to reduce the air resistance. That is, the bypass damper 150 is closed when cooling using the cooling member 155, and is opened when the cooling is not performed, thereby functioning as a kind of resistance avoiding damper. If the bypass damper 150 is opened when the air conditioner is not in operation, the air resistance is reduced and the power consumption required to drive the blower can be reduced. That is, when the bypass damper 150 is opened, the driving power of the blowing unit 160 is reduced.

The cooling member 155 may serve to cool the outside air once passed through the water removing unit 140 again. Here, the cooling member 155 may be an oval coil. That is, the cooling member 155 may be formed of an elliptical copper pipe so as to minimize the air resistance and improve the cooling performance in the rear of the coil. Such an elliptical coil can maintain a low static pressure even at high wind speed, which is suitable for energy saving.

The cooling member 155 is a resistor, and is a device required only when the refrigerator is started, such as a summer season. In other words, the cooling member 155 is unnecessary at the time of cooling the outside air, and in particular, since the blower power is a loss factor, the bypass damper 150 is opened and operated during the unused period of the cooling member 155, have.

The blowing unit 160 serves to supply the outside air introduced through the outside air inflow unit 110 to the server room 200 side. That is, by providing the blowing section 160 in the natural air flow path that moves along the evaporating cooler 130, the water removing unit 140, the bypass damper 150, and the cooling member 155 arranged in a straight line, The outside air introduced through the outside air inflow part 110 is supplied to the server room 200 side. The blower 160 is provided with a high-efficiency BLDC fan, which makes it possible to reduce operating costs in comparison with a general AC fan.

A plurality of blowers may be installed in the blowing unit 160. For example, the blowing units may be stacked in three rows and three columns so that a total of nine blowers can be installed. At this time, the position of the blower can be arranged at a desired position, and the air flow rate can be adjusted by adjusting the number of blowers. At this time, the unused blowing part may be blocked by the cover to prevent the backflow of air.

In this way, the modular server room cooling apparatus can be implemented by changing the arrangement of the blowers of the blowing unit 160, thereby enabling the arrangement and expansion of the blower units freely freely as needed, It is possible to realize a server room cooling apparatus which is more advantageous for cooling of the server room. In other words, the scalability and variability of the server room cooling system can be seen to increase.

4 and 5, the relief damper 170 may control the pressure of the hot zone (HZ) in the server room 200. In detail, in a conventional server room cooling apparatus, if the hot zone (HZ) exhaust amount and the cool zone (CZ) supply amount do not match, there is a problem that the cooling effect of the server is lowered when the hot zone is pressurized . In order to solve such a problem, the server room cooling apparatus 100 according to an embodiment of the present invention further includes a relief damper 170 for relieving the hot zone pressure. When the pressure of the hot zone is increased, The pressure of the hot zone can be lowered by opening the damper 170. That is, when the pressure of the hot zone is increased, the plate 172 moves along the axis 171 by the pressure, and a space is created, and the air in the hot zone escapes into this space. 4, the shaft 171 is formed to be inclined at a certain angle with respect to the vertical plane so that when the pressure of the hot zone is increased, the plate 172 can be formed to easily move along the shaft 171 have.

The exhaust unit 180 may serve to discharge a part of the air in the server room 200 to the outside. For example, a high efficiency BLDC fan is applied to the exhaust part 180, which makes it possible to reduce operating costs in comparison with a general AC fan.

The mixing damper 190 sucks the heat of the server room 200 to mix with the cool outside air introduced from the outside air inflow part 110. Thereby, temperature control of the air for proper cooling can be performed.

The server room 200 is formed on one side of the mixing unit 101 and the cooling unit 102 and a plurality of server racks 210 are arranged in the server room 200 along the first direction. At this time, each server rack 210 may have a plurality of servers.

In this case, a region connected to the cooling unit 102 in the server room 200 to receive cold air from the cooling unit is a cool zone (CZ), and hot air passing through the server rack 210 is discharged Is a hot zone (HZ).

The cold air supplied to the cool zone CZ flows into the server rack 210, passes through a plurality of servers provided in the server rack 210 and is heated by the hot zone HZ, The mixture is discharged to the outside via the mixing damper 190 or is supplied again to the mixing portion 101 via the mixing damper 190. Therefore, the cool zone CZ is opened in connection with the cooling section 102, and the hot zone HZ is blocked from the cooling section 102. [ Here, for efficient cooling of the server, the hot zone HZ and the cool zone CZ are blocked by the shielding member 220, the cool zone CZ is connected to the cooling unit 102, The hot zone HZ is cut off from the cooling unit 102 to supply hot air RA to the exhaust unit 180 provided in the upper portion of the server room 200 As shown in Fig.

Cool air (SA) supplied to the cool zone (CZ) of the server room (200) is supplied to each series of server racks (210) and discharged from the server rack (210) The hot air (RA) enters the hot zone (HZ). The air introduced into the hot zone HZ may be exhausted to the outside through the exhaust unit 180 or may be introduced into the mixing unit 101 as necessary.

Although not shown in the drawing, a rail is formed on the bottom of the server room 200, and a sliding guide is formed on a lower surface of the server rack 210, As shown in Fig. Here, the moving direction of the server rack 210 may be substantially the same as the traveling direction of the air. As described above, the server rack 210 is configured to be movable in the forward and backward directions with respect to the server room 200, thereby facilitating the installation and management of a modular server room cooling apparatus in a narrow data center.

Although not shown in the figure, a cable track (not shown) may further be provided on the upper portion of the server rack 210, particularly, on the hot zone HZ side of the server rack 210. The cable track (not shown) is a device for securing the flexibility of the power / communication cable as the server rack 210 slides forward and backward. For example, the cable track collects and concentrates one or more power / communication cables so as not to scatter, and guides the movement path of power / communication cables when the server rack 210 slides back and forth can do.

According to the present invention as described above, the cooling air required for cooling the server is cooled by using the cool outside air, so that the operation time of the cooling device is reduced, and the energy required for cooling is greatly reduced.
