Meanwhile, although eight fan blades 113 according to the present embodiment are shown to be installed along the radial direction of the first rotary plate 112, the embodiments of the present invention are not limited thereto. That is, the number of the fan blades 113 according to the present embodiment is not particularly limited. For example, the fan blades 113 may be composed of various numbers such as two, four, and so on.

The second rotating plate 114 is installed between the fan driving motor 111 and the first rotating plate 112 and rotates together with the rotation of the first axis AX1.

The fixed plate 115 is disposed below the second rotary plate 114 to support the second rotary plate 114 so that the second rotary plate 114 can be elevated and lowered and the elevating actuator 116 provided on the support SP is connected to the fixed plate 115, (115).

A second bearing B may be interposed between the second rotating plate 114 and the fixed plate 115 so that the second rotating plate 114 is rotatable relative to the fixed plate 115 As shown in FIG.

One end of the angle control rod 118 is connected to the rotation guide rod 117, The angle of the fan blade 113 can be adjusted by rotating the fan blade 113 according to the ascending and descending of the second rotating plate 114. [

Specifically, the angle control rod 118 rotates the rotation guide rod 117 counterclockwise to rotate the fan blade 113 counterclockwise when the second rotation plate 114 rises. On the contrary, when the second rotary plate 114 is lowered, the angle control rod 118 rotates the rotary guide rod 117 in the clockwise direction, and the fan blade 113 also rotates in the clockwise direction.

The fan blade 113 according to the present embodiment can rotate clockwise and counterclockwise around the first rotary plate 112 when viewed from above the upper rotary plate 112. However, The case where the fan blade 113 rotates clockwise about the first rotary plate 112 will be mainly described.

Referring to FIG. 5A, the fan blade 113 according to the present embodiment is inclined so as to have an angle of -α (counterclockwise) with respect to the horizontal direction. When the fan blade 113 having such a configuration rotates clockwise together with the rotation of the first rotating plate 112, the direction opposite to the gravity is rotated by the rotation of the fan blade 113 as indicated by the solid arrow in FIG. 6 A flow of air can be formed.

Accordingly, when the fan blade 113 rotates, an air flow is generated in which the air in the housing 120 is exhausted to the upper side. When the fan blade 113 rotates, the cooling vanes move to the upper side of the rotary vane device 170 and the heat And may be introduced into the housing 120 through the exchange part 130.

5 (b) shows a state in which the fan blade 113 is inclined so as to have an angle of +? (Clockwise) with respect to the horizontal direction. When the fan blade 113 having such a configuration rotates clockwise together with the rotation of the first rotary plate 112, the fan blade 113 rotates in the direction of gravity A flow can be formed.

Therefore, when the fan blade 113 rotates, air flows into the housing 120 to flow outside air into the housing 120, and then flows to the outside of the housing 120 And can be discharged to the outside of the housing again through the disposed rotary vane device 170 and the heat exchanging part 130. Accordingly, according to such driving, dust and foreign substances inside the housing 120 can be discharged to the outside.

According to the fan apparatus 110 of the present embodiment as described above, the angle of the fan blade 113 can be controlled by controlling the driving of the lift actuator 116. [ Further, although not shown in the figure, the elevating actuator 116 may be connected to a separate control circuit (not shown) so that the operator can remotely control the elevating actuator 116 by a wire / wireless signal.

Meanwhile, when a temperature sensor (not shown) is installed in the air outlet 123a and supercooling is detected in the compressor cooling apparatus 100, the angle of the fan blade 113 is automatically adjusted It is also possible to perform a drive for converting to a normal operation state.

As described above, since the fan device 110 according to the present embodiment can adjust the angle of the fan blade 113, it is possible to control the flow rate of the fluid passing through the fan blade 113. Accordingly, the operator can arbitrarily control the angle of the fan blades 113 to suit the maximum capacity of the compressor cooling apparatus 100, so that the air volume of the fluid discharged or flowing into the housing 120 can be adjusted, Power consumption can be prevented.

According to the fan device 110 of the present embodiment, the angle of the fan blade 113 can be controlled without the same configuration as that of an expensive inverter provided for adjusting the air volume of the cooling device 100 for the compressor Therefore, the cost can be reduced, and the installation space and weight of the cooling apparatus 100 for the entire compressor can be reduced, and the space can be utilized efficiently.

First, the installation of the cooling device 100 for a compressor will be described.

As shown in FIG. 1, the installer separates the compressor 10 and the cooling device 100 for a compressor in a predetermined indoor installation space. The cooling device 100 for the compressor is an independent module separated from the compressor 10 so that a connection pipe D is provided between the compressor 10 and the cooling device 100 for the compressor, (100). Although not shown in FIG. 1, in the present embodiment, since the cooling apparatus 100 for a compressor is installed in an indoor space, the air 123a of the lid unit 123 is capable of discharging heated air to the outside It is preferable that ducts are connected and installed.

On the other hand, as shown in Fig. 10, the installer can install the compressor 10 in the room and install the cooling device 100 for the compressor in the outdoor. In this case, not only the indoor installation space can be reduced, but also the cooling performance of the compressor cooling apparatus 100 is improved.

Next, the operation of the cooling apparatus 100 for a compressor according to the present embodiment will be described.

When the operator operates the compressor 10, the turbo compression devices 11, 12 and 13 of the compressor 10 are operated.

The turbo compression device 11 compresses the drawn air up to the first stage pressure and discharges the compressed air to the first intermediate cooling heat exchanging part 131a via the first fluid inlet part 141 And heat exchange is performed. Here, heat exchange in the first intermediate cooling heat exchanging portion 131a is performed as follows.

That is, when the fan blade 113 rotates to cause the air in the housing 120 to be discharged to the upper side, external air flows through the rotary vane unit 170 and the first intermediate cooling heat exchanging unit 131a And the heat exchanged and heated air is discharged from the inside of the housing 120 to the upper side by the air flow.

 The compressed air cooled by the first intermediate cooling heat exchanging part 131a is transferred to the first moisture separator 161 to be separated from moisture and then passed through the first fluid discharge part 151, D to the turbocompressor 12.

The air drawn into the turbo compression device 12 is compressed and discharged to the second end pressure by the turbo compression device 12. The compressed air discharged from the turbo compression device 12 is transferred to the second intermediate cooling heat exchanging part 131b via the second fluid inlet part 142 to perform heat exchange.

Here, heat exchange in the second intermediate cooling heat exchanging part 131b is performed as follows. That is, when the fan blade 113 rotates to cause the air in the housing 120 to be discharged to the upper side, external air flows through the rotary vane device 170 and the second intermediate cooling heat exchanger 131b And the heat exchanged and heated air is discharged from the inside of the housing 120 to the upper side by the air flow.

 Then, the compressed air cooled by the second intermediate cooling heat exchanging part 131b is transferred to the second moisture separator 162 to be separated from moisture, then passed through the second fluid discharging part 152, D to the turbo compression unit 13.

The air drawn into the turbo compression device 13 is compressed and discharged to the third stage pressure by the turbo compression device 13. The compressed air discharged from the turbo compression device 13 is transferred to the post-cooling heat exchanger 132 via the third fluid inlet 143 to perform heat exchange. Here, heat exchange in the post-cooling heat exchanger 132 is performed as follows.

That is, when the fan blade 113 rotates to cause the air in the housing 120 to be discharged to the upper side, external air flows through the rotary vane device 170 and the post-cooling heat exchanger 132 And the heat exchanged and heated air is discharged from the inside of the housing 120 to the upper side by the air flow.

The compressed air cooled by the post-cooling heat exchanging part 132 is transferred to the third moisture separator 163 to separate the moisture and then to the third fluid discharging part 153, To the compressor 10 again or directly to the next stage device (e.g., a combustor, etc.).

On the other hand, the lubricating oil circulates in the compressor (10), and the circulating lubricating oil performs the lubrication of the rotor structure or the like in the compressor (10). A lubricating oil reservoir (not shown) and a lubricating oil pump (not shown) are provided in the compressor 10 for circulating the lubricating oil. By the operation of the lubricating oil pump, The oil is transferred to the oil-cooling heat exchanger 133 via the oil passage 144 and the heat exchange is performed.

Here, heat exchange in the oil-cooling heat exchanger 133 is performed as follows. That is, when the fan blade 113 rotates to cause the air in the housing 120 to be discharged to the upper side, external air flows through the rotary vane device 170 and the oil cooling heat exchanger 133 And the heat exchanged and heated air is discharged from the inside of the housing 120 to the upper side by the air flow.

The oil cooled in the oil-cooling heat exchanger 133 passes through the fourth fluid outlet 154 and is returned to the lubricating oil reservoir (not shown) in the compressor 10 through the connection conduit D Move.

The operator adjusts the angle of the vanes 171 of the rotary vane apparatus 170 before or during operation of the compressor cooling apparatus 100 to adjust the air flow rate through the heat exchanging unit 130, The cooling action of the cooling device 100 for the compressor can be controlled.

As described above, since the cooling device 100 for a compressor according to the present embodiment is installed as an independent module separated from the compressor 10, the configuration of the compressor 10 is simplified and the volume thereof is reduced, Thereby reducing the installation space, and facilitating installation and maintenance.

The cooling apparatus 100 for a compressor according to the present embodiment is provided with a heat exchanging unit 131 for intermediate cooling, a heat exchanging unit 132 for post-cooling, Since the exchange unit 133 and the moisture separator 160 are disposed together, the installation and maintenance of the cooling apparatuses can be facilitated owing to the unified module structure, and the installation space can be reduced.

According to the cooling apparatus 100 for a compressor according to the present embodiment, a plurality of heat exchanging units 130 are disposed together in one compressor cooling apparatus 100, and the cooling function of the heat exchanging unit 130 Is performed simultaneously with the single fan unit 110, so that it is possible to reduce the number of motors used and save energy in the cooling operation.

In addition, since the cooling apparatus 100 for a compressor according to the present embodiment includes the moisture separator 160, a separate piping facility for installing the moisture separator in the compressor 10 is not required. Therefore, the installation space of the compressor 10 is reduced, and the space utilization of the entire system including the compressor 10 and the cooling apparatus 100 for a compressor is also excellent.

The cooling device 100 for a compressor according to the present embodiment includes a rotary vane device 170 so that the operator can adjust the angle of the vanes 171 of the rotary vane device 170, 100 can easily be controlled.
