Hereinafter, the structure of the first embodiment of the cooling tower according to the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 is a front view showing a first embodiment of a cooling tower according to the present invention, and FIG. 2 is a longitudinal sectional view showing a first embodiment of the present invention.

1 and 2, the cooling tower 1 according to the present embodiment includes a casing 100, a water supply unit 200, a blowing device 300, a filler material 400, and a water collecting unit 500 do. The casing (100) defines a predetermined space in which components other than the blowing device (300) are installed among the components constituting the cooling tower (1). The water supply unit 200 serves to supply cooling water to be heat-exchanged. The air blowing device 300 is installed outside the casing 100 so as to be separated from the casing to flow air to be heat-exchanged with the cooling water. The filling material 400 is a place where heat exchange is performed between cooling water supplied by the water supply unit 200 and air flowing by the blower 300. Also, the water collecting part 500 is a place where air and heat exchange cooling water are collected.

More specifically, the casing 100 is formed in a predetermined shape, for example, a hexahedron shape. At this time, the casing 100 may be made of a metal material, or may be made of concrete or reinforced concrete.

The casing (100) is provided with an air inlet (110) and an air outlet (120). The air inlet 110 is a place where air is sucked into the casing 100 and the air outlet 120 is a place where air is discharged to the outside of the casing 100. In the present embodiment, the inlet port 110 is located on the bottom surface of the casing 100, and the outlet port 120 is located on the top surface of the casing 100. Preferably, at least a part of the projection of the exhaust port 120 formed in the bottom surface of the casing 100 in the vertical direction may be located apart from the air inlet 110. This is to allow the air sucked into the casing 100 through the air inlet 110 to flow evenly inside the casing 100.

The casing (100) is provided with a shroud (131). The shroud 131 extends into the casing 100 so as to have a predetermined height at a bottom surface of the casing 100 corresponding to the outer periphery of the intake port 110. The shroud 131 serves to guide air sucked through the air inlet 110.

In the present embodiment, the casing 100 is supported by the pilot 140 such that its bottom surface is spaced upward from the ground. For example, the pillow 140 may support four bottom edges of the casing 100. The height of the pilotty 140 is determined to be less than the height of the air blowing device 300. The height of the blowing device 300 may be substantially the same as the length between the upper end of the blowing fan 310 described later and the bottom of the blowing motor 320 described later.

The water supply unit 200 includes a water supply pipe 210 and a water supply nozzle 220. The water supply pipe 210 is a place where cooling water to be heat-exchanged with air flows. The water supply nozzle 220 is a place where cooling water flowing through the water supply pipe 210 is injected. For example, the water supply pipe 210 is inserted into the casing 100 through a surface of the casing 100, and the water supply nozzle 220 is connected to the water supply pipe 210 at a predetermined interval Can be spaced apart.

The air blowing device 300 includes a blowing fan 310 and a blowing motor 320. The blowing fan 310 serves to flow air. That is, when the blowing fan 310 rotates, the air is sucked into the casing 100 through the inlet 110 to exchange heat with the cooling water, and the air exchanged with the cooling water flows through the exhaust port 120 And is discharged to the outside of the casing (100). As the blowing fan 310, for example, an axial flow fan may be used. The blowing motor 320 provides a driving force for rotating the blowing fan 310. The fan motor 320 is provided with a motor shaft 321 and the blowing fan 310 is directly coupled to the motor shaft 321. In this embodiment, As described above, in the present embodiment, the air blowing device 300 is installed outside the casing 100, substantially below the casing 100. In other words, the weight of the blowing fan 310 and the blowing motor 320 is not transmitted to the casing 100. Also, in the present embodiment, the blowing fan 310 is positioned inside the shroud 131.

The filler material 400 is located above the intake port 120 and in the internal space of the casing 110 corresponding to the water pipe 210. Substantially the filler material 400 will be positioned directly below the water supply tank 210. For example, the filler material 400 may include a plurality of fillers spaced apart from each other. The cooling water injected from the water supply nozzle 220 substantially flows through the filler material 400, that is, the surface of the filler, while being in contact with the air to be heat-exchanged.

The water collecting part 500 is located between the air blowing device 300 and the filler material 400, that is, above the air blower device 300 and below the filler material 400. The water collecting part 500 collects cooling water heat exchanged with the air while flowing along the surface of the filler. The cooling water collected in the water collecting part 500 is heat-exchanged with a working fluid flowing in an air conditioning system (not shown) or a cooling system (not shown). In this embodiment, the collecting part 500 includes a plurality of collecting members 510 and a plurality of drainage members 520. The water collecting member 510 is spaced apart from each other to allow air to flow by the air blowing device 300. The water collecting member 510 may be formed in a manner such that the cooling water heat-exchanged with the air in the filling material 400 flows to the lower surface of the casing 100, May be positioned on another water collecting member 510 adjacent thereto. However, the water collecting member 510 may be formed in any shape or may be arranged in any form as long as the air can flow and the flow of the cooling water can be restricted. The drain member 520 discharges the cooling water collected in the water collecting member 510 to the outside.

The cooling tower 1 may further include a scattering-preventing member 600. The scattering-preventing member 600 serves to prevent scattering of cooling water heat-exchanged with air in the casing 100. The scattering-preventing member 600 may be located above the water supply pipe 210 or may be located on the exhaust port 120, for example.

Hereinafter, the operation of the embodiment of the cooling tower according to the present invention will be described in more detail with reference to the accompanying drawings.

3 is a longitudinal sectional view showing the operating state of the first embodiment of the cooling tower according to the present invention.

3, air is sucked into the casing 100 through the inlet 110 when the fan 300 is rotated, that is, when the blowing fan 310 rotates by the blowing motor 320. The cooling water flowing in the water supply pipe 210 is sprayed by the water supply nozzle 220 and flows along the surface of the filler material 400. The cooling water flowing along the surface of the filler material 400 contacts the air flowing in the casing 100 through the inlet 110 by the rotation of the blowing fan 310 to perform heat exchange. The cooling water and the heat exchanged air flow through the casing 100 by the continuous rotation of the blowing fan 310 and then discharged to the outside of the casing 100 through the exhaust port 120.

However, in the present embodiment, as described above, the blowing fan 310 and the blowing motor 320 are provided outside the casing 100. Therefore, the size of the casing 100 can be relatively reduced. Since the weight of the blowing fan 310 and the blowing motor 320 is not transmitted to the casing 100, the consideration of the strength of the casing 100 may be relatively reduced. Also, vibrations from the blowing fan 310 and the blowing motor 320 may be transmitted to the casing 100 to be amplified, and the generation of noise due to the vibration may be relatively reduced. In addition, the operation of the inside of the casing (100) becomes possible during the operation of the air blowing device (300).

Hereinafter, the configuration of a cooling tower according to a third embodiment of the present invention will be described in detail with reference to the accompanying drawings.

4 is a longitudinal sectional view showing a second embodiment of a cooling tower according to the present invention. The same components as those of the first embodiment of the present invention among the constituent elements of the present embodiment are denoted by reference numerals of FIGS. 1 to 3, and a detailed description thereof will be omitted.

Referring to FIG. 4, in the cooling tower 2 according to the present embodiment, the pilotty 140 is designed to have a length equal to or longer than the height of the blowing device 300. The shroud 132 provided on the bottom surface of the casing 100 extends to the outside of the casing 100 to have a predetermined height.

Hereinafter, a second embodiment of the cooling tower according to the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 5 and 6 are front views showing a cooling tower according to a third embodiment of the present invention, and FIG. 7 is a longitudinal sectional view showing a third embodiment of the present invention. The same components as those of the first embodiment of the present invention among the constituent elements of the present embodiment are denoted by reference numerals of FIGS. 1 to 3, and a detailed description thereof will be omitted.

5 to 7, in the cooling tower 3 according to the present embodiment, the pilotty 140 is designed to have a length equal to or longer than the height of the air blowing device 300. The cooling tower 3 further includes a moving device 700 for moving the blowing device 300 in a direction adjacent to the casing 100 and in a direction away from the casing 100, that is, up and down.

More specifically, the mobile device 700 may include, for example, a base 710, a guider 720, and a drive member (not shown). The base 710 is a place where the blowing device 300 and the blowing motor 320 are substantially supported. The guider 720 serves to guide the up and down movement of the base 710. The driving member provides a driving force for moving the base 710 up and down. Therefore, when the driving member is driven, the base 710 moves up and down along the guider 720. Of course, the configuration of the mobile device 700 is not limited thereto, and any configuration can be applied as long as the mobile device 700 can move the blower device 300 up and down.

The moving device 700 can move the blowing device 300 up and down depending on whether the cooling tower 3 is operating, that is, whether the blowing device 300 is operating. That is, when the cooling tower 3 is operated and the fan unit 300 operates, the moving unit 700 moves the fan unit 300 upward. At this time, the moving device 700 moves the blowing device 300 upward so that the blowing fan 310 is positioned inside the shroud 131. On the contrary, when the operation of the cooling tower 3 is stopped and the blowing device 300 is stopped, the moving device 700 moves the blowing device 300 downward. At this time, the moving device 700 moves the blowing device 300 downward so that the blowing fan 310 is positioned outside the shroud 131.

In summary, in the present embodiment, the blowing fan 310 is selectively positioned on the inside and outside of the shroud 131 depending on whether the blowing device 300 is operated or not. Therefore, it is possible to repair or replace the blowing fan 310 more easily.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
