3 to 7, the flow rate increasing Internet data center air conditioning system 10 of the present invention includes a cooler 500 for entering and exchanging air in an indoor space of an Internet data center 12, A duct 13 installed on the floor of the indoor space and a blowing unit 100 connected to the duct 13 to supply the heat exchanged cooling air of the cooler 500 to the inside of the Internet data center.

As shown in FIG. 4, the blow-in unit 100 is connected to a duct 13 installed on the floor of the indoor space, and supplies the cooling air supplied through the duct 13 to the indoor space.

The airflow 100 is installed opposite to each other and driven by a pair of rotating means 120 rotating in the opposite direction, so that the cooling air flows into the space between the rotating means 120. The rotating speed of the rotating means 120 increases the wind speed and the air flow rate, The cooling air is supplied to the indoor space of the Internet data center 12 by switching the air blowing direction.

Here, the inflow portion 100 includes a case 110, a rotating means 120, and a guiding means 130.

That is, in the case 110, a connection hole 111 is formed so that the floor duct 13 of the indoor space in which the server is installed is communicated with both side surfaces, and a discharge hole 112 for discharging air is formed in the upper portion.

Here, the connection hole 111 may be formed on the lower surface of the case.

The rotating means 120 is arranged to face the inner space 113 of the case 110 and rotate in opposite directions to generate and increase the air flow rate and wind speed.

In addition, the guide means 130 are arranged in a pair and have a curved shape which is arranged close to the rotation means 120.

When the guide means 130 guides the flow of the cooling air supplied from the duct 13 to the rotating means 120 and guides the flow to the discharge hole 112, the guide means 130 increases the wind speed of the cooling air by the rotating means 120 The air on the side of the inflow space 131 formed between the pair of guide means 130 is pulled to be discharged to the discharge hole 112 with an increased air flow rate.

Here, the rotating means 120 is connected to the motor 121, and a plurality of blades 123 are mounted on the outer circumference of the shaft 122 having a rotating length. At this time, the motor 121 is disposed inside the rotating means 120. That is, a plurality of blades 123 are arranged to surround the motor 121, and the shaft 122 is connected to the motor 121 through the rotating means 120.

In addition, a partition wall 140, which is vertically extended to an inner space 113, is provided at an end of the discharge hole 112 of the case 110 to extend the length of the discharge hole 112, and the guide unit 130 has a curved curvature, And the other side is disposed to face the connection hole 111 side.

This allows the cooling air supplied through the duct 13 to flow naturally into the indoor space of the Internet data center 12 by the arrangement of the partition 140 and the guide unit 130 as described above.

The functions of the power supply unit 100 configured as described above are as follows.

The inflow portion 100 is connected to the duct 13 and installed at the bottom of the indoor space of the Internet data center 12.

The air supply unit 100 receives the cooling air generated by the cooler 500 from the duct 13 and supplies the cooling air to the indoor space of the Internet data center 12.

Here, when the cooling air flows into the case 110 from the duct 13, the airflow-supplying portion 100 is branched into two spaces and supplied.

That is, the cooling air is supplied to the rotating means 120 side through the guide means 130 and the cooling air is supplied to the inlet space 131 between the pair of guide means 130.

At this time, the air pressure is raised by reciprocal rotation of the pair of rotating means 120, thereby increasing the air pressure in the space between the pair of rotating means 120 to increase the wind speed.

That is, when the air pressure in the space between the pair of rotation means 120 and the guide means 130 is increased, the air pressure in the inflow space 131 outside the guide means 130 is lowered.

As a result, the force of the air acts as a low pressure in the high pressure, so that the cooling air whose air velocity has been increased through the pair of rotating means 120 pulls the airflow in the inflow space 131 and increases the airflow.

In other words, the blowing section 100 changes the air blowing direction of the cooling air supplied through the duct 13 to supply the indoor air to the indoor space of the Internet data center 12, while improving the wind speed and air volume of the cooling air, It is effective to improve the cooling efficiency of the indoor space of the Internet data center 12 by providing the center 12 as an indoor space.

5, the circulation unit 200 is installed at the bottom of the indoor space of the Internet data center 12.

The circulation unit 200 circulates the cooling air in the vicinity of the bottom of the indoor space without being connected to the duct 13.

That is, the hot heat of the indoor space of the Internet data center 12 is raised by the convection, and the cold heat is present at the bottom of the indoor space.

At this time, the circulation unit 200 circulates cold cooling air at the bottom of the indoor space of the Internet data center 12 and is discharged to the upper part of the indoor space of the Internet data center 12, so that the indoor space of the Internet data center 12 has a uniform cooling temperature distribution cloth .

 The circulation unit 200 includes a case 210, a rotation unit 220, and a guide unit 230.

The case 210 is installed on the floor of the indoor space of the Internet data center 12 and has an outlet 211 and an inlet 212 formed on the upper part thereof.

The rotating means 220 is provided in a pair and rotates in opposite directions while being disposed opposite to the inner space 213 of the case 210.

In addition, the guide means 230 are provided in a pair and have a curved shape which is arranged close to the rotation means 220.

The circulation unit 200 configured as described above causes the indoor air to flow into the case 210 through the inlet 212 by the rotation unit 220 and guide the air flow to the outlet 211 side through the guide unit 230. The circulation unit 200, The air on the side of the inlet space 231 formed between the pair of guide means 230 is drawn out to be discharged to the outlet 211 side in an increased air flow rate.

Here, the rotating unit 220 is connected to the motor 221, and a plurality of blades 223 are mounted on the outer circumference of the shaft 222 having a length to rotate.

Particularly, in the circulation part 200, a partition 240 is formed at the boundary between the outlet 211 and the inlet 212 of the case 210 to separate the outlet 211 and the inlet 212, respectively, and the partition 240 is vertically extended into the internal space 213 of the case 210 , The guide means 230 is directed to the inner periphery of the bottom of one side exit 211 of the curved curvature and the other side is arranged horizontally below the inlet 212. [

So that the air in the indoor space of the Internet data center 12 flows through the inlet 212 and flows through the rotating means 220 to the outlet 211 easily.

The function of the circulation unit 200 configured as described above is as follows.

The circulation unit 200 is not connected to the duct 13 but is installed at the bottom of the indoor space of the Internet data center 12.

When the pair of rotating means 220 is rotated inside the case 210, the air in the indoor space of the Internet data center 12 flows into the internal space 213 through the inlet 212 of the case 210.

The air introduced through the inlet 212 is supplied to the rotating means 220 through the guide means 230 and is branched and supplied to the inflow space 231 between the pair of guide means 230.

At this time, the air supplied into the space between the rotating means 220 and the guide means 230 increases air pressure by raising the air pressure by reciprocal rotation of the pair of rotating means 220 to increase the air pressure in the space between the rotating means 220 and the guide means 230 .

When the air velocity increases as the air pressure in the space between the pair of rotation means 220 and the guide means 230 increases, the air pressure in the inflow space 231 outside the guide means 230 is lowered.

As a result, since the force of the air acts as a low pressure in the high pressure, the air whose air velocity is increased through the pair of rotating means 220 pulls the airflow in the inflow space 231 side to increase the airflow.

In addition, the effect of circulating the air in the indoor space of the Internet data center 12 by discharging the air of increased wind speed and air volume through the circulation unit 200 to the outlet 211 side to maintain the overall cooling temperature distribution of the indoor space of the Internet data center 12 have.

In addition, the airflow exchanging unit 400 is further included in the upper portion of the indoor space of the Internet data center 12 to provide a warm upward flow of the indoor space to the cooler 500.

That is, the circulation unit 200 has a function of circulating the cold cooling air on the bottom side of the indoor space, and the airflow exchange unit 400 allows the hot ascending airflow above the ceiling side of the indoor space to flow from the indoor space to the cooler 500.

As a result, the cooling air that has been heat-exchanged through the cooler 500 is supplied to the indoor space of the Internet data center 12 through the air blower to exchange heat in the indoor space, and the circulating unit 200 circulates the air on the floor side of the indoor space to have uniform heat distribution And the airflow exchanging part 400 allows the hot air present in the upper part of the indoor space to flow to the cooler 500.

Thus, the cooling air is circulated in the indoor space.

In addition, a plurality of sensing means 310 are installed in the indoor space of the Internet data center 12.

The sensing means 310 is a means for measuring the temperature, and is provided in a plurality of places in the indoor space of the Internet data center 12.

Then, the sensing means 310 applies the measured temperature value to the control unit 300.

The control unit 300 can control the blowing unit 100 and the circulation unit 200 individually according to an applied temperature value so that the temperature can be adjusted to the set indoor temperature.

As described above, the server racks 14 are arranged at regular intervals in the indoor space of the Internet data center 12, and the circulation unit 200 connected to the duct 13 and the circulation unit 200 connected to the duct 13 at the space bottom between the server racks 14 are alternately So that the cooling air is supplied to the space between the server racks 14 through the blowing unit 100 and the cold cooling air at the bottom side of the space between the server racks 14 in which the circulation unit 200 is installed is circulated, .

The hot ascending air existing in the upper portion of the indoor space is guided to the cooler 500 through the air stream exchanging unit 400 so as to perform heat exchange so that air in the indoor space of the Internet data center 12 is circulated while exchanging heat.

7, protrusions 610 protrude from one end of each blade 123 in a downward direction. The protrusion 610 is formed along the edge of the side on which the blade 123 advances during the rotation of the rotating means 120 and protrudes to a predetermined height so as to face the inside of the rotating means 120.

A vortex may occur when the air passing through the rotating means 120 moves along the blade 120. According to an embodiment of the present invention, the vortices may be decomposed by the protrusions 610 to prevent irregular flow of air. Thus, the air passes smoothly through the rotating means 120, and the flow rate of the discharged air can be increased. In addition, the noise generated when the air passes through the rotation means 120 due to the decrease of the vortex can be reduced.
