DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a louver panel used for a cooling tower for cooling hot water discharged from factory equipment, air conditioning equipment, etc. 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, as an example, a schematic configuration of a cross flow type cooling tower and a cooling method thereof will be described 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 flowing hot water 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.

As shown in FIG. 5, a conventional louver is provided on site with a louver corrugated plate 33 on a louver support 32 attached to a column 31 constituting a framework of a cooling tower.
And the two are fastened with the 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 expensive, and furthermore, the louver corrugated plate 33 may be damaged due to excessive tightening of the nut 35 during assembly. 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, all parts were installed on site, requiring a lot of on-site assembly man-hours, and the high level of work required a high degree of danger.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to eliminate the possibility of damaging the louver corrugated sheet, eliminating the need for refastening,
It is an object of the present invention to provide a cooling tower louver panel that can be easily installed.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the gist of the present invention is to provide a louver panel for use in a cooling tower for cooling hot water flowing down in a filler block by an airflow taken from a louver. Are connected by a plurality of horizontal rails, a plurality of louver supports are projected from each of the louver pillars obliquely upward, and a louver corrugated plate is attached to the louver supports. And a pair of hanging fittings and a pair of positioning hooks attached to the louver panel of the cooling tower.

[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,
A wire) is inserted, lifted by a lifting machine such as a crane, and attached to the cooling tower by locking a positioning hook with a locking member provided on the cooling tower support.

[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 figure, reference numerals 1 and 1 denote louver supports arranged in parallel, and the louver supports 1 and 1 are connected by three horizontal rails 2. A louver support 3 protrudes obliquely upward from the vicinity of the horizontal bar 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 at 0 and attaching the bolt 11 to the member (not shown) attached to the cooling tower support 9 through the small hole 8.

[0013]

As described above, the louver panel according to the present invention has the following effects. By assembling in advance at the factory, the number of man-hours required for assembling cooling towers on site can be reduced because on-site installation can be easily carried out on the cooling tower support using a lifting device such as a crane using hanging brackets and positioning hooks. I do.

When assembled at a factory, the valleys of the louver corrugated sheet can be fastened using ordinary bolts and nuts, so that there is little risk of damaging the louver corrugated sheet and there is no need to retighten.
