Description

[0001] COOLING TOWER AND COOLING SYSTEM [0002]

The present invention relates to a cooling tower and a cooling system.

The cooling tower serves to cool the cooling water, for example, the air conditioner or the refrigerator, that is, the cooling water used for condensing the refrigerant flowing in the refrigeration cycle by bringing it into contact with air. In order to heat-exchange the high-temperature cooling water, such a cooling tower causes the cooling water to be blown into the air or to make the flowing cooling water come into contact with the air to be blown.

In such a cooling tower, components constituting a cooling tower such as a water supply section, a blowing section, a filler, and a collecting section are provided inside a casing defining an external appearance. The cooling water supplied from the water supply unit flows along the filler material, and is heat-exchanged with air sucked into the casing by driving the air supply unit. In this way, the cooling water and the heat-exchanged air are discharged to the outside of the casing by the continuous driving of the blowing portion, and the cooling water heat-exchanged with the air is collected in the collecting portion.

Prior arts 1 to 3 disclose cooling towers according to the prior art. In the prior art, generally, inlet ports through which air is sucked for heat exchange with cooling water are located on both sides of the casing. However, since air is sucked into the inside of the casing only through one of the inlet port and the suction port formed only on one side of the casing in accordance with the installation location of the cooling tower and the distance to the adjacent cooling tower, It can be done as an enemy. In such a case, the conventional cooling tower is disadvantageous in that heat exchange between the cooling water and the air is inefficiently performed because the flow of air is concentrated in the region adjacent to the inlet port relatively.

The casing (100) defines a predetermined space in which the components constituting the cooling tower (1) are installed. The water supply unit 200 serves to supply cooling water to be heat-exchanged. The blowing unit 300 serves to flow air to be heat-exchanged with the cooling water. The filler material 400 is a place where heat exchange is performed between cooling water supplied by the water supply unit 200 and air flowing through the airflow supply unit 300. The water storage unit 500 includes the filler 400 ) Where the heat-exchanged cooling water is collected. The air guide 600 serves to guide air sucked into the casing 100.

More specifically, the casing 100 is formed in a predetermined shape, for example, a hexahedron shape. The casing (100) is provided with an air inlet (110) and an air outlet (120). The intake port 110 and the exhaust port 120 are places where air enters and exits to the inside and outside of the casing 100. In the present embodiment, the air inlet 110 is located only on one side of the casing 100, and the air outlet 120 is located on the upper center of the casing 100. Therefore, in this embodiment, the amount of the air flowing through the filler material 400 may vary depending on the distance from the inlet 110 to the inside of the casing 100, especially for the heat exchange with the cooling water.

A fan stack 130 is provided on the upper surface of the casing 100. The fan stack 130 serves to guide the air exhausted through the exhaust port 120. The fan stack 130 may be formed as a polyhedron that extends upward by a predetermined length from the upper surface of the casing 100 and has an open top and bottom, for example, a cylindrical shape.

The water supply unit 200 includes a water supply pipe 210 and a nozzle 220. The water supply pipe 210 is a place where cooling water to be heat-exchanged with air flows. The nozzle 220 is a portion where cooling water flowing through the water supply pipe 210 is injected toward the filler material 400.

Meanwhile, the blowing unit 300 includes a blowing fan 310 and a blowing motor 320. The air blowing fan 310 serves to flow air into and out of the casing 100. 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 filling material 400 is positioned inside the casing 100 between the inlet 120 and the water supply pipe 210. The cooling water injected from the nozzle 220 flows along the space between the filler material 400 or the filler material 400 and is heat exchanged by contacting with air.

In the water collecting part 500, the cooling water which is heat-exchanged with the air while flowing along the surface of the filler 400 is collected. The water collecting part 500 is positioned below the casing 100 corresponding to the lower portion of the air inlet 110.

Meanwhile, the air guide 600 is positioned inside the casing 100 between the filling material 400 and the collecting part 500. The air guide 600 substantially extends from the air inlet 110 toward the interior of the casing 100. One end of the air guide 600 is positioned adjacent to one side of the casing 100 on which the air inlet 110 is formed and the other end of the air guide 600 is positioned on the other side of the casing 100. [ As shown in FIG. In the present embodiment, the air guides 600 are positioned so as to be spaced apart from each other in the horizontal direction. The air guide 600 is formed in a polygonal shape having a bottom surface and both ends opened. An inclined portion 610 is provided on an upper surface of the air guide 600. The inclined portion 610 serves to reduce the noise generated when the cooling water heat-exchanged with the air in the filling material 400 hits the air guide 600 and to guide the cooling water to the water collecting part 500 . The inclined portion 610 may have, for example, a triangular-shaped longitudinal cross-section. Of course, the inclined portion 610 may be separately formed and provided on the upper surface of the air guide 600, or the noise generated by the cooling water may be generated on the surface of the inclined portion 610 or the upper surface of the air guide 600 May be provided.

Referring to FIGS. 3 and 4, when the blowing fan 310 rotates, air is sucked into the casing 100 through the inlet 110. The air sucked into the casing 100 flows through the casing 100 by the continuous rotation of the blowing fan 310 and then flows through the air outlet 120 to the inside of the casing 100, And is discharged to the outside.

The cooling water flowing through the water supply unit 200 and the water supply pipe 210 is injected through the nozzle 220 and flows through the space between the surface of the filler material 400 or the filler material 400. The cooling water flowing along the filler material 400 contacts the air flowing in the casing 100 and is heat-exchanged. The heat exchanged cooling water is collected in the water collecting part 500 and then transferred to an external water storage tank (not shown).

In the present embodiment, since the inlet port 110 is provided only on one side of the casing 100, the amount of air flow in the casing 100 differs according to the distance from the inlet port 110. That is, a small amount of air will flow inside the casing 100, which is relatively spaced from the inlet port 110, relative to the inside of the casing 100, which is relatively adjacent to the inlet port 110, It may be difficult to expect efficient heat exchange between the air and the cooling water.

However, in this embodiment, a part of the air sucked through the air inlet 110 is guided to a region spaced from the air inlet 110 through the air guide 600. Therefore, according to the embodiment of the present invention, even when the inlet port 110 is formed only on one side of the casing 100, heat exchange between the cooling water and the air can be efficiently performed in the casing 100 as a whole .

Also, the air guide 600 is substantially located between the filling material 400 and the collecting part 500. Therefore, there is a possibility that the cooling water heat-exchanged with the air in the filler material 400 hits the air guide 600 to generate noise. However, in this embodiment, the cooling water is guided by the inclined portion 610 formed on the upper surface of the air guide 600, so that the noise generated when the cooling water hits the air guide 600 can be reduced.
