TECHNICAL FIELD OF THE INVENTION
The present invention relates to a louver support that can easily install a louver installed on an external air inflow side of a cooling tower, and a louver support mounting structure.
[0002]
[Prior art]
Conventionally, cooling towers used to cool and circulate hot water discharged from factory facilities and air conditioning equipment in buildings and the like have been sprayed with hot water from the water spray section to the filler that performs heat exchange, Spray hot water was cooled by heat exchange with air, and the hot water cooled in the receiving tank was collected. In this case, there is a problem that the hot water sprayed from the water spraying part is scattered from the outside air inflow side of the cooling tower. In order to solve this problem, a plurality of louvers are installed at equal intervals on the external air inflow side to prevent water spattering and scattering.
However, the installation of the louvers is very troublesome since each louver is fixed.
[0003]
Therefore, a method for simplifying the installation of the louver has been studied.
FIG. 1 of Patent Document 1 shows a louver support having an I-shape and having fastening holes for fastening louvers at predetermined intervals. The louver support is not illustrated with an opening that opens at one end of the louver support, but with a fastening hole. For this reason, as a method of mounting the louver, at the site where the cooling tower is installed, after attaching the louver support between one edge of the tray of the cooling tower and the watering tank base, insert the louver into the louver fixing hole I was going. However, when inserting the louver into the fixing hole, the support of the cooling tower was in the way, and the insertion was performed while bending the louver so as not to hit the support. In addition, it was a cause of damaging the louver.
[0004]
Also, the method of locking the upper end of the louver support is such that two horizontal plate portions of the sprinkler tub are punched out to form a folded piece, and the upper end of the louver support is sandwiched between the two folded pieces. Therefore, after the louver support was installed, the folded pieces were folded back and sandwiched.
[0005]
Further, as another conventional example, in FIG. 1 of Patent Document 2, the partition plate and the brace are alternately attached in the column longitudinal direction such that the partition plate and the brace protrude from the partition column, and placed on the brace. A cooling tower having a structure in which a louver end and a brace are fastened by a fastening member is described. However, in order to fix the corrugated louvers, there are many parts such as partition columns, crosspieces, partition plates, and fastening members, and the corrugated louvers are fixed to the crosspieces one by one using the fastening members. Was a very time-consuming task.

[0013]
As shown in FIGS. 3 and 4, the louver support 1 includes a louver insertion portion 11 having an opening width d2 larger than the louver thickness d1 and a louver engaging portion for engaging the louver in an L-shaped angle member. 12, a louver fitting fulcrum 13 such that one end of the louver 2 is engaged when the louver is fitted, a louver support portion 14 adapted to the shape of the louver lower surface so as to support the louver, and a louver width end. The number of the louvers 2 is formed on the punching surface 16 of the L-shaped angle with the louver opening 10 having the fitting portion 15 into which the louver 22 is fitted. Further, as shown in FIGS. 1 and 2, the louver support 1 has a notch 16 provided below the louver support 1 so as to be sandwiched by a tray support frame 42 provided on one edge 41 of the tray.
[0014]
The shape of the louver 2 may be any shape that can prevent scattering. Preferably, as shown in FIG. 4, the thickness of the louver 2 is made thinner in terms of cost, and the width direction of the louver 2 is made into an arc shape in order to prevent bending in the length direction. Further, in order to maintain strength and prevent breakage at the time of fitting, the end portion 22 in the width direction of the louver is formed in a rib shape or one end portion in the length direction of the louver. As the material of the louver, any material may be used as long as it has weather resistance and water resistance, but a general-purpose resin such as PVC is preferable from the viewpoint of cost and molding.
