The cooling tower serves to cool cooling water, for example, cooling water used for condensation of refrigerant flowing through an air conditioner or refrigerator, that is, a refrigeration cycle. In such a cooling tower, cooling water is supplied into the air in order to heat exchange the high-temperature cooling water, or the flowing cooling water is cooled by contacting air sucked into the cooling tower.

However, the following problems arise in the cooling tower according to the prior art.

First, conventionally, a cooling tower, substantially a casing, is provided with an intake port through which air is sucked into the interior thereof, and such an intake port is shielded by a separate shield member when the cooling tower is not in operation. However, in the related art, there is an inconvenience that the operator must perform the work of fixing a separate shielding member to the casing.

In addition, in the cooling tower, it is preferable that the suction amount of the air exchanged with the cooling water is adjusted according to the temperature of the cooling water that is heat-exchanged with the air. For example, by adjusting the number of rotations of a blowing fan that sucks air into the cooling tower in proportion to the temperature of the cooling water, substantially the number of rotations of the fan motor, or/and the opening of the intake port through which air is sucked into the cooling tower, air Increase the amount of inhalation. However, in order to control the rotation speed of the blowing fan, a component such as an inverter must be added to the rotation speed of the fan motor, and a damper or a louver must be installed on the intake port so as to be rotatable to adjust the opening degree of the intake port. Therefore, conventionally, it is cumbersome to control the amount of air intake through the intake port.

On the other hand, the opening and closing device 600 is installed on both side surfaces of the casing 100, substantially, on at least one side surface of the casing 100 in which the intake port 110 is formed. In this embodiment, the opening and closing device 600 includes the first and second housings 611 and 612, the first and second drums 621 and 622, the opening and closing member 630, and a drive motor (not shown). ).

In more detail, the first and second housings 611 and 612 are disposed to face each other on the edge of the intake port 110. In FIG. 1, the first and second housings 611 and 612 are shown to be horizontally disposed above and below the intake port 110, but the first and second housings 611 and 612 ) May be disposed on both sides of the intake port 110 in a vertical direction. Of course, when the first and second housings 611 and 612 are disposed in a vertical direction on both sides of the intake port 110, the support slot 140 corresponds to the upper and lower ends of the intake port 110. It will be provided long in the horizontal direction on both sides of the casing 100. For example, the first and second housings 611 and 612 may be formed in a hollow polyhedral shape having a length greater than or equal to the width of the intake port 110 in the horizontal direction. In addition, first and second openings 612A and 612A through which the opening/closing member 630 enters and exits are formed on a bottom surface of the first housing 611 and an upper surface of the second housing 612, respectively.

The first and second drums 621 and 622 are rotatably installed inside the first and second housings 611 and 612, respectively. At this time, the first and second drums 621 and 622 are formed in a cylindrical shape that is elongated in the horizontal direction, and rotate around an axis in the horizontal direction. Substantially, the first and second drums 621 and 622 rotate while both ends of the opening/closing member 630 in the longitudinal direction, that is, the upper and lower ends, are fixed respectively.

Next, the opening/closing member 630 is positioned on the intake port 110 to open the intake port 110 or shield the intake port 110. Substantially, the opening/closing member 630 opens the intake port 110 or shields the intake port 110 according to a position relative to the intake port 110.

Referring to FIG. 2, in this embodiment, the opening/closing member 630 includes a shielding portion 631, an opening portion 632, and first and second fixing portions 633A and 633B. The shielding part 631 is defined by a part of the opening/closing member 630 and when positioned on the intake port 110 shields the intake port 110. In addition, the opening portion 632 is defined by another part of the opening/closing member 630, and opens the intake port 110 when positioned on the intake port 110. To this end, a plurality of vent holes 630H communicating with the intake port 110 are formed in the opening part 632. The first and second fixing portions 633A and 633B are defined by both ends of the opening/closing member 630 excluding the shielding portion 631 and the opening portion 632. Accordingly, the opening/closing member 630 can be said to be continuous in the order of the first fixing part 633A, the shielding part 631, the opening part 632, and the second fixing part 633B.

In this embodiment, one of the shielding part 631 and the opening part 632 is selectively positioned on the intake port 110, so that the intake port 110 is opened and closed. To this end, the shielding portion 631 and the opening portion 632 may be formed in a shape and size corresponding to the entire intake port 110. For example, when the cooling tower 1 is stopped, the shielding part 631 is located on the intake port 110, and when the cooling tower 1 is operated, the opening part 632 is It will be located on (110).

In addition, the first and second fixing portions 633A and 633B are fixed to the first and second drums 621 and 622, respectively. In this way, in a state in which the first and second fixing parts 633A and 633B are fixed to the first and second drums 621 and 622, respectively, the shielding part 631 and the first fixing part ( 633A) or the opening part 632 and the second fixing part 633B are wound around the first and second drums 621 and 622 or released from the first and second drums 621 and 622. , One of the shielding part 631 and the opening part 632 is selectively positioned on the intake port 110.

On the other hand, the opening portion 632 may be formed of a plurality of different total areas of the ventilation holes 630H per unit area. For example, as shown in FIG. 2, the opening portion 632 may include first and second opening portions 632A and 632B. The first and second openings 632A and 632B are the sum of the areas of the ventilation holes 630H per unit area, that is, the opening degree of the intake ports 110 when substantially positioned on the intake ports 110 It is classified according to. That is, in the first opening portion 632A, the sum of the areas of the ventilation holes 630H per unit area is set relatively large, and in the second opening portion 632B, the number of the ventilation holes 630H per unit area The sum of the areas is set relatively small. Therefore, when the first opening part 632A is located on the intake port 110, the second opening part 632B is in communication with the intake port 110 compared to the case where the second opening part 632B is located on the intake port 110. By increasing the sum of the areas of the ventilation holes 630H, the opening degree of the intake port 110 will be relatively increased.

In addition, the driving motor provides a driving force for rotation of at least one of the first and second drums 621 and 622. For example, as shown in FIG. 2, the driving motor may include first and second driving motors that provide driving force for rotation of the first and second drums 621 and 622, respectively. . Accordingly, when the first and second drums 621 and 622 are rotated by the first and second driving motors, the opening/closing member 630 is moved to the first and second drums 621 and 622. It is wound or released from the first and second drums 621 and 622.

Of course, the drive motor is deleted, and at least one of the first and second drums 621 and 622 may be manually rotated by an operator. In this case, a handle or a lever for rotating at least one of the first and second drums 621 and 622 may be provided.

On the other hand, this embodiment further includes a temperature sensor (not shown). The temperature sensor detects the temperature of the cooling water supplied from the water supply unit 200, that is, the temperature of the cooling water heat-exchanged with air through the intake port 110. For example, the temperature sensor may detect the temperature of the cooling water supplied from the water supply tank 210 or the cooling water supplied to the water supply tank 210.

In addition, the opening/closing device 600 adjusts the opening degree of the intake port 110 according to the temperature of the cooling water sensed by the temperature sensor. For example, when the opening portion 632 includes the first and second opening portions 632A and 632B, the first and second opening portions 632A ) One of 632B may be selectively positioned on the intake port 110. For example, when the temperature of the cooling water sensed by the temperature sensor is equal to or higher than a preset first reference temperature T1, the first opening portion 632A is positioned on the intake port 110. In addition, when the temperature of the cooling water sensed by the temperature sensor is less than the first reference temperature T1, the second opening portion 632B is positioned on the intake port 110. Here, the first reference temperature T1 is the cooling capacity of the cooling tower 1, that is, the amount of cooling water supplied from the water supply unit 200 per unit time, the output of the air blower 300 or the intake port 110 In consideration of the size of ), it may be set so that the cooling of the coolant can be achieved at a designed level.

Therefore, when the opening and closing member 630 is wound around the first and second drums 621 and 622 or released from the first and second drums 621 and 622, one side of the opening and closing member 630 In a state pressed by the pressing member 720, foreign substances attached to the surface of the opening/closing member 630 may be removed by the scraper 710.

Hereinafter, the operation of the cooling tower according to the first embodiment of the present invention will be described in more detail.

First, when the blowing fan 310 is rotated by the fan motor 320, the air sucked into the casing 100 through the intake port 110 passes through the filler 400. In addition, the air sucked through the intake port 110 is heat-exchanged with the cooling water supplied from the water supply unit 200 and substantially the water supply water supply tank 210 while passing through the filler 400.

Next, the air heat-exchanged with the coolant in the filler 400 by the continuous rotation of the blowing fan 310 is discharged to the outside of the casing 100 through the exhaust port 120. In addition, the cooling water heat-exchanged with air in the filler 400 is collected in the water collecting unit 500 and then recycled to heat exchange with the load.

On the other hand, in this embodiment, the intake port 110 is selectively opened or closed by the opening/closing device 600, or the opening degree of the intake port 110 is adjusted. That is, when the cooling tower 1 is operated, a part of the opening/closing member 630, substantially the opening part 632 is positioned on the intake port 110 to open the intake port 110, and the cooling tower 1 When this is stopped, another part of the opening/closing member 630, that is, the shielding part 631 is positioned on the intake port 110 so that the intake port 110 is shielded.

In particular, in this embodiment, the opening degree of the intake port 110 is adjusted according to the temperature of the cooling water that is heat-exchanged with air in the filler 400, that is, the temperature of the cooling water detected by the temperature sensor. More specifically, when the temperature of the cooling water sensed by the temperature sensor is equal to or higher than a preset first reference temperature T1, the first opening portion 632A is positioned on the intake port 110. However, when the temperature of the cooling water sensed by the temperature sensor is less than the first reference temperature T1, the second opening portion 632B is positioned on the intake port 110. Accordingly, in this embodiment, the opening degree of the intake port 110 is adjusted according to the temperature of the cooling water, so that the amount of air sucked into the cooling tower 1 for heat exchange with the cooling water can be adjusted.

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

As described above, the arrangement of the ventilation holes 640H takes into account the flow of air sucked into the casing 100 through the intake port 110. That is, when the blowing fan 310 rotates, a large amount of air is introduced into the casing 100 through the lower portion of the intake port 110 compared to the upper portion of the intake port 110. This is due to the relative position of the blowing fan 310 and the intake port 110. Accordingly, in this embodiment, the sum of the areas of the ventilation holes 630H per unit area of the opening portion 632 is gradually increased from the top to the bottom, thereby substantially adjusting the opening of the intake port 110. The amount of inhalation of can be controlled more efficiently.

Is located on the top. That is, substantially, in this embodiment, the relative position of the opening part 642 with respect to the intake port 110 is changed according to the temperature of the cooling water sensed by the temperature sensor, so that the opening degree of the intake port 110 is adjusted. do.

For example, if the temperature of the cooling water detected by the temperature sensor is a preset second reference temperature T2, the sum of the areas of the ventilation holes 630H communicating with the intake port 110 is a preset reference area (A ), a part of the opening part 632 is positioned on the intake port 110. Here, the second reference temperature (T2) and the reference area (A), similar to the first reference temperature (T1), will be set so that cooling of the cooling water can be achieved at a designed level in consideration of the cooling capacity of the cooling tower 1 .

And, if the temperature of the cooling water sensed by the temperature sensor exceeds the second reference temperature (T2), in proportion to the temperature of the cooling water sensed by the temperature sensor, the ventilation hole 640H communicating with the intake port 110 Another part of the opening part 642 is positioned on the intake port 110 so that the sum of the areas increases compared to the reference area A. Conversely, if the temperature of the cooling water detected by the temperature sensor is less than the second reference temperature T2, the ventilation hole 640H communicating with the intake port 110 is proportional to the temperature of the cooling water detected by the temperature sensor. Another part of the opening part 642 is positioned on the intake port 110 so that the sum of the areas is reduced compared to the reference area A. In other words, when the temperature of the coolant detected by the temperature sensor is greater than or less than the second reference temperature T2, the temperature of the coolant detected by the temperature sensor is relatively As a result, the relative position of the opening part 642 with respect to the intake port 110 is changed to increase or decrease the opening degree of the intake port 110.

Within the scope of the basic technical idea of the present invention, many other modifications are possible for those of ordinary skill in the art, as well as the scope of the present invention should be interpreted based on the appended claims. .
