2. Description of the Related Art Conventionally, a cooling tower used to cool and circulate hot water discharged from factory equipment, air-conditioning equipment such as buildings, and the like has been used for cooling hot water. From the point of view of the system, the so-called "cross flow system" in which the flow directions of the hot water and the cooling air flow are at right angles.
There is a so-called "counterflow method" in which the flow directions of the hot water and the cooling airflow are opposite to each other. The present invention is applicable to a cross-flow type, and in order to facilitate understanding of the present invention, a schematic configuration of a cross-flow type cooling tower and its cooling system will be described with reference to FIG. In the figure, the filler blocks 22, 22 are installed on both sides of the ventilation space 21.

A large number of small holes 2 are formed on the bottom surface of each hot water distribution tank 24.
7, hot water is supplied to the filler block 22 through the small holes 27, and the supplied hot water flows down in the filler block 22. On the other hand, the flow F of air from the louver 28 on the side of the filler block 22 through the filler block 22 into the ventilation space 21 by the cooling fan 23.
Occurs, and the hot water flowing down in the filler block 22 is cooled by this air flow F. 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.

Among the four outer side surfaces of the cooling tower for cooling hot water by the above-described method, the louvers 28 are installed on the two opposite surfaces, through which air flows, but as shown in FIG. An exterior plate (corrugated plate) 31 is provided on the remaining two surfaces to block the flow of air and prevent water leakage. When mounting the exterior plate 31, as a frame structure,
Two columns are erected, and these columns are connected by braces (oblique beams) and beams (horizontal beams), but this is a large scaffold from the stand height (often about 6 m or more). It is essential to install each brace, each beam and bolt
Since it had to be mounted using a fastening member such as a nut, a lot of man-hours were required for local assembly.

After the frame structure is completed, the exterior plate is attached. Since the size of the exterior plate is various,
The on-site installation work was extremely complicated.

Further, the outer plate is a corrugated plate so as to withstand deformation, and corresponds to the shape of the corrugated plate so that water does not leak to the outside from the overlapping portion of the corrugated plates on the side of the filler block. A sealing material 32 having a peak portion and a trough portion and having a shape as shown in FIG. 6 is inserted in the longitudinal direction of the corrugated plate, but the on-site insertion work is not easy and the sealing material is damaged at the time of insertion. In some cases, it was not possible to completely prevent water leakage.

The present invention has been made in view of the above problems of the prior art, and its purpose is to assemble on-site without much labor and time, and is a problem peculiar to a cooling tower.

In the cooling tower, which comprises a hot water distribution tank for supplying hot water above the material block, a cold water tank below the filling material block, and cools the hot water flowing down through the filling material block by an airflow taken from the louver, the exterior panel Comprises a second panel attached to both sides of the first panel below, and a third panel attached to the outside of each second panel, the second panel being lateral to the filler block. A cooling tower characterized by being located is the first invention. The first panel is formed by vertically connecting a plurality of unit panels to which exterior plates are attached.
In the second panel, two columns are arranged in parallel, the widthwise ends of the exterior plate are arranged along the columns, and the exterior plate is fixed to the columns, and the ends of the exterior plate are T-shaped. The base end portion of the decorative plate having a T-shaped cross section is fixed to the support pillar so as to surround the above, and the sealing material is inserted into both end portions of the exterior plate. The third panel is a frame with an exterior plate attached.

In the cooling tower in which a plurality of cooling towers according to the first aspect of the present invention are connected, the partition panel at each connection point is constructed by attaching a fifth panel to both sides of the following fourth panel. A cooling tower characterized by the above is a second invention. The fourth panel is formed by vertically connecting a plurality of unit panels having partition plates.

In the fifth panel, two columns are arranged in parallel, the end portions in the width direction of the partition plate are arranged along the both columns, and the partition plate is fixed to the column.

[0011]

According to the cooling tower of the first invention, the exterior panel is divided into the first to third panels, so if these panels are assembled in the factory in advance, the work on site will be done after the assembly. Only the first to third panels need to be connected to each other, the on-site assembly work is simple, and the cooling tower exterior panel can be completed in a short time. Also, by assembling the panel at the factory, it becomes easy to insert the sealing material for preventing water leakage. Furthermore, since both ends of the exterior plate in which the sealing material is inserted are surrounded by decorative plates having a T-shaped cross section, water leakage can be reliably prevented. According to the cooling tower of the second invention, since the partition wall panel is composed of the fourth and fifth panels, these fourth,
If the fifth panel is assembled in the factory in advance, the on-site assembly work of the cooling tower composed of a plurality of cells can be performed in a short time.
