Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a louver panel used in a cooling tower for cooling hot water discharged from factory equipment, air conditioning equipment and the like with high efficiency.

[0002]

2. Description of the Related Art Conventionally, a cooling tower used for cooling and circulating hot water discharged from an air conditioner of a factory facility, a building or the like has been equipped with a cooling water system. From the viewpoint of the system, the flow direction of the hot water and the cooling airflow is at right angles, that is, the so-called “cross-flow method”, and the flow directions of the hot water and the cooling airflow are opposite.
There is a so-called "counter flow system", and the louver panel of the present invention can be applied to any type of cooling tower. Therefore, in order to facilitate understanding of the present invention, a schematic configuration of a cross-flow type cooling tower and its cooling method will be described as an example with reference to FIG.

In FIG. 1, a filler block 22 is provided on both sides of a ventilation space 21, a cooling fan 23 is mounted above the ventilation space 21, and a hot water distribution tank 24 is provided above each filler block 22. The hot water is supplied to the hot water distribution tank 24 from a hot water supply pipe 25 via a sprinkling box 26. A plurality of small holes 27 are formed in the bottom surface of each hot water distribution tank 24, and the filler block 2 is formed through the small holes 27.
2 is supplied with hot water, and the supplied hot water flows down in the filler block 22. On the other hand, the cooling fan 23 causes the louver 28 on the side of the
2, a flow F of air flowing toward the ventilation space 21 is generated, and the airflow F cools the hot water flowing down in the filler block 22. Then, the air that has exchanged heat with the hot water is discharged to the outside after water drops are separated by the eliminator 29. As described above, in the cross-flow type cooling tower, the hot water flowing down is cooled by the airflow supplied from the lateral direction. Thus, the hot water that has passed through the filler block 22 becomes cold water and is stored in the cold water tank 30. The counterflow type cooling tower is different in that the flowing hot water is cooled by a rising airflow and a countercurrent method, but the configuration and function of the louver are the same.

By the way, in the conventional louver, as shown in FIG. 5, a louver corrugated plate 33 is installed on-site on a louver support 32 attached to a column 31 constituting a framework of a cooling tower.
Was mounted and the both were fastened with hook bolts 34. When fastening the hook bolts, nut 35
However, since it is difficult to tighten the nuts at the valleys at the site, the hook bolts 34 are attached to the peaks 36 of the louver corrugated plate 33. However, the hook bolt 34 is high in cost, and in addition, the nut 35 may be excessively tightened at the time of assembly to damage the louver corrugated plate 33. In addition, the louver corrugated plate 33 deteriorates with time, and the peak portion 36 becomes low. Therefore, the fastening portion is loosened, and the louver corrugated plate 33 is sometimes forced to be retightened.
In addition, since all the components are mounted on site, a large number of local assembly man-hours are required, and since the work is performed at high places, the risk is high.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to prevent the louver corrugated plate from being damaged and to prevent re-tightening.
It is to provide a louver panel for a cooling tower that can be easily installed.

[0006]

In order to achieve the above object, the gist of the present invention is a louver panel used in a cooling tower for cooling hot water flowing down in a filler block by an air flow taken from the louver, which is a parallel panel. The two louver columns arranged in the above are connected by a plurality of horizontal bars, and a plurality of louver supports are projected obliquely upward from each of the above louver columns, and a louver corrugated plate is attached to the louver supports to form one horizontal bar. A louver panel of a cooling tower, characterized in that a pair of hanging fittings and a pair of positioning hooks are attached to the louver panel.

[0007] The pair of suspension fittings and the pair of positioning hooks are provided at the uppermost stage in order to maintain the stability of the louver panel when the louver panel is suspended and to make it easy to attach the positioning hook to the cooling tower support. Preferably, it is attached to the crosspiece.

It is preferable that the interval between the two louver columns is matched with the interval between the cooling tower columns in order to facilitate attachment to the cooling tower columns.

[0009]

The operation of integrating a plurality of louver corrugated sheets into a louver panel can be performed at a factory in advance. When assembled in a factory, the louver supports can be fastened to the valleys of the louver corrugated sheet using ordinary bolts and nuts, so there is little risk of damaging the louver corrugated sheet and there is no need for retightening. When attaching a louver panel incorporating a plurality of louver corrugated sheets to a cooling tower, a suspending jig (for example,
Wire), and is lifted by a lifting machine such as a crane, and the positioning hook is locked by a locking member provided on the cooling tower column, thereby being attached to the cooling tower.

[0010]

Embodiments of the present invention will be described below. FIG. 1 is a perspective view of a louver panel according to the present invention. In the drawing, reference numerals 1 and 1 denote louver columns arranged in parallel, and the louver columns 1 and 1 are connected by three horizontal rails 2. A louver support 3 projects obliquely upward from the vicinity of the cross rail 2 of each louver support 1, and a louver corrugated plate 4 is attached to the louver support 3. By assembling the louver panel of the present invention at a factory, as a fastening member for attaching the louver corrugated sheet 4 to the louver support 3, as shown in FIG.
, And the fastening portion of the bolt 5 can be a valley of the louver corrugated plate 4. The louver corrugated plate of this embodiment has three stages, but is not limited to this. The number of louver corrugated sheets to be incorporated in the louver panel should be two or more steps in order to increase the efficiency of the assembly work. However, there is no limit to the upper limit of the number of steps. It is preferable to decide after comprehensively examining.

Further, as shown in FIG. 1, a pair of suspension fittings 6 and a pair of positioning hooks 7 are attached to the horizontal rail 2 of the louver support. 8 is a small hole for inserting a bolt or the like.

In order to attach the louver panel having such a configuration to the cooling tower, a wire or the like is inserted into the hanging bracket 6 and lifted by a lifting machine such as a crane, and the positioning hook 7 is moved to the cooling tower support as shown in FIG. Locking member 1 attached to 9
The louver panel can be fixed by locking with 0, and inserting the bolt 11 into the small hole 8 and attaching it to a member (not shown) attached to the cooling tower column 9.

[0013]

As described above, the louver panel according to the present invention has the following effects. By assembling in the factory in advance, it is possible to easily attach it to the cooling tower column by using a lifting machine such as a crane using the hanging metal fittings and the positioning hook, so the number of assembly steps of the cooling tower on the site is reduced. To do.

When assembling in the factory, since the valley portion of the louver corrugated plate can be fastened using ordinary bolts and nuts, there is little risk of damaging the louver corrugated plate, and there is no need to re-tighten it.
