The following description relates to a swing type coil device and a cooling method using a swing type coil.

Servers, network equipment, enterprise equipment, etc. in the data center generate heat. Therefore, the data center operating these equipment also operates a large-scale facility to cool the heat. To cool the heat in the data center, cool air must be supplied to each piece of equipment. For example, Korean Patent No. 10-1548328 discloses a server room cooling apparatus and a data center air conditioning system having the same.

The power consumption of the blower used for the supply of air is related to the air flow rate and the resistance (static pressure loss). For example, the blowing power can be calculated as shown in Equation 1 below.

In the embodiment of FIG. 1, the lower portions of the coil portions 120 and 130 are fixed in consideration of the traveling direction of the air, and the upper portions of the coil portions 120 and 130 are moved to explain the example in which the coil portions 120 and 130 are inclined The upper portions of the coil portions 120 and 130 are fixed and the coil portions 120 and 130 are fixed according to the embodiment (for example, when the air passage passes through the swing type coil device, May be designed so that the coil parts 120 and 130 are inclined.

In order to provide a cooling function of the swing-type coil device, it is possible to maximize the cooling function by regulating the inclination of the coil parts 120 and 130 so that the coil parts 120 and 130 are perpendicular to the air flow path.

2 is a photograph showing an embodiment of a swing type coil device according to an embodiment of the present invention. The photograph 200 includes driving units 210 and 220 for controlling inclination of the coil units 120 and 130 and the coil units 120 and 130 and coil units 120 and 130, And pipes 230 and 240 which are flexible and adjustable according to the inclination of the coil parts 120 and 130 and the coil parts 120 and 130, And a frame 250 for fixing the driving units 120 and 130 and the driving units 210 and 220, respectively.

As described above, when the cooling function is not operating, the tilt of the coil units 120 and 130 can be controlled so as to be inclined toward the air flow direction through the driving units 210 and 220. In this case, by minimizing the resistance of the air by the cooling coil, the power consumption of the blower can be reduced. When the cooling function is in operation, the coil parts 120 and 130 control the inclination so as to be perpendicular to the air flow path through the driving parts 210 and 220, thereby cooling the air passing through the coil parts 120 and 130 Function can be provided.

6 is a flowchart illustrating a cooling method using a swing type coil device according to an embodiment of the present invention. The cooling method according to the present embodiment can be performed by a control device associated with the swing type coil device. For example, in the server room cooling apparatus 100 described with reference to FIG. 1, a plurality of swing type coil apparatuses may exist, and a plurality of swing type coil apparatuses and a plurality of configurations And a swing type coil device according to the present embodiment can be performed by a control device included in such server room cooling device 100. [

In step 610, the control device can confirm whether the cooling function of the swing type coil device disposed on the air flow path of the air conditioner is in operation. For example, the controller of the server room cooling apparatus 100 can determine whether the swing-type coil device is in operation or not, and can determine whether the swing-type coil device is currently in operation or not have. For example, the server room cooling apparatus 110 may be provided with a measurement unit (not shown) for measuring temperature and / or humidity. The measuring unit may include, for example, a temperature sensor for measuring temperature and / or a humidity sensor for measuring humidity. At this time, the server room cooling apparatus 110 can check whether the cooling function is operated according to the temperature or humidity measured by the measuring unit. As described above, whether or not the cooling function of the swing type coil device is in operation can be determined according to predetermined values for various external conditions, and the control device can confirm whether or not the cooling function is activated. As another example, the control device may check whether or not the swing coil device is in operation according to a preset time, a time period, or the like in connection with the operation of the cooling function of the swing coil device.

In step 620, the control unit controls the driving unit included in the swing type coil unit according to whether the cooling function is activated or not, thereby controlling the inclination of the coil unit included in the swing type coil unit. For example, when the control device is to operate the cooling function of the swing type coil device, the control device controls the inclination of the coil portion included in the swing type coil device so as to be perpendicular to the air blowing path so that air on the air passage is cooled through the coil portion. can do. Conversely, when the cooling function of the swing-type coil device is not in operation, the control device controls the coil portion to tilt in the direction of air flow in the air flow path, thereby minimizing the resistance of the air, thereby reducing power consumption of the blower.

Thus, to control the tilt of the coil part, the controller may perform step 621, step 622 and step 623 in step 620. [

In step 622, the controller may control the driving unit so that the coiled portion inclined in the direction in which the air advances on the airflow path is vertically disposed on the airflow path. For example, the control device may be implemented as a gas-type shock absorber or a pneumatic cylinder to draw a coil portion through a drive shaft connected between at least one side of a left side surface of a coil portion and a right side surface of a coil portion and a frame, It can be controlled to be vertically arranged on the path.

In step 623, the controller may control the driving unit so that the coil portion vertically disposed on the air flow path is inclined in a direction in which the air advances on the air blowing path. For example, the control device can push the coil part through the drive shaft described above and control the coil part to tilt in the direction in which the air advances on the air blowing path.

Further, as already described, the coil portion is divided into two stages of the upper coil portion (for example, the first coil portion 120 described above) and the lower coil portion (for example, the second coil portion 130 described above) . In this case, the controller controls the first driving unit connected to the upper coil unit in step 620 to control the inclination of the upper coil part, and controls the second driving unit connected to the lower coil part to control the inclination of the lower coil part . Further, when there are a plurality of swing type coil devices, the control device can control each of the swing type coil devices through a cooling method like the embodiment of Fig.

In step 710, the control device may supply the refrigerant through a piping portion that is flexibly regulated according to the inclination of the coil portion to enable the cooling function. At this time, in step 710, the controller supplies the refrigerant through an articulated first pipe connected to the inlet pipe formed on the first side of the coil part and flexibly adjusted according to the inclination of the coil part, And the supply and discharge of the refrigerant can be controlled so that the refrigerant discharged from the coil portion is transmitted to the outside through the articulated second pipe connected to the further formed outlet pipe and flexibly adjusted according to the inclination of the coil portion.

This step 710 may be performed as determined in step 621 of FIG. 6 to activate the cooling function depending on whether the cooling function is activated or not. For example, step 710 may be performed in parallel with step 622. [
