Description

[Detailed Description of the Invention] The present invention relates to a heat exchange filler housed in a cooling tower, and aims to improve heat exchange efficiency.

As a conventionally known heat exchange filler for cooling towers, there is a material in which a large number of parallel grooves are formed on the surface of each mountain side of a corrugated plate formed in a zigzag shape, and each groove has a single groove at each end. These grooves create a turbulent flow of water flowing on the corrugated plate surface, but since many grooves are arranged in parallel, the turbulent flow of water is also uniform. Although it was possible to reduce the water flow rate, it was not completely satisfactory.
Therefore, heat exchange between water and air in a cooling tower is not fully satisfactory, and it is desired to improve heat exchange efficiency.

The present invention was devised to address this problem, and aims to provide a heat exchange filler that promotes water turbulence and improves heat exchange efficiency.

Hereinafter, the present invention will be explained based on drawings showing an example of implementation. In the figure, reference numeral 1 is a corrugated sheet made of synthetic resin formed in a zigzag shape, and the inclination angle of the many peaks is approximately 60 degrees with respect to the horizontal plane. Fig. 2 shows the corrugated plate 1 developed into a flat plate, and as can be seen from Fig. 2, the surfaces of the mountainside portions 3, 3 on both sides sandwiching the ridge portion 2 of each mountain are A large number of parallel grooves 4 are arranged in parallel on the left and right, and the left and right grooves 4 are staggered with each other, and the ends of the left and right grooves 4 are aligned with each other in the center of the mountainside portion 3. formed to overlap. Furthermore, in the adjacent mountainside portions 3, the grooves 4 are divided by the ridge portions 2 and the valley portions 5, and are staggered.

Therefore, as shown in Figs. 1 and 3, a large number of corrugated plates 1 having a large number of grooves 4 (about 10 pieces) are stacked to form a heat exchange filler. Adjacent corrugated sheets 1, 1 are stacked so that the slopes of the ridges are in opposite directions. Furthermore, when a large number of corrugated sheets 1 are stacked, there are alternating portions where the front surfaces of the corrugated sheets 1 face each other and portions where the back surfaces of the corrugated sheets 1 face each other, and the grooves are formed in the portions where the back surfaces of the corrugated sheets 1 face each other. A protrusion 6 is formed on the back surface portion of 4. Further, as described above, by stacking a large number of corrugated sheets 1, the ridge portions 2 and 2 and the trough portions 5 and 5 of adjacent corrugated sheets 1 contact each other at an inclined angle, and the corrugated sheets 1 ，
1, a complex passage 7 is formed between them.

When a large number of corrugated plates 1 configured as described above are stored and used in a cooling tower, the grooves 4
... and protrusions 6 ... are present in a staggered manner on each mountainside portion, so water is sprinkled from above and the passage 7
The water that enters inside falls in the form of a liquid film while encountering resistance. At that time, a turbulent flow of water occurs in the grooves 4 and the protrusions 6, and the other flat parts of the grooves 4...
and the turbulent flow generated at the protrusions 6... is made effective. As mentioned above, since the grooves 4 and the protrusions 6 exist in a staggered manner, turbulent flow of water occurs effectively, increasing the contact area between water and air, and increasing sensible heat due to contact between water and air. , the transfer of latent heat due to water evaporation increases, improving the cooling effect. In addition, the resistance caused by the turbulent flow slows down the flow of water and increases the residence time, which increases the contact time between water and air and improves the cooling effect.

As described above, according to the present invention, grooves and protrusions are arranged on both sides of the corrugated plate in a staggered manner on each hillside, which improves the turbulent flow effect of water and reduces the contact area with air. The contact time is increased and the heat exchange efficiency is improved.
