Benefits of technology

The present invention provides a plastic rod for use in a fabrication of a pneumatic resilient foam (PRSF) that has several advantages such as maximizing cooling of water, being solid in construction, and being of relatively small size. The plastic rods are thin in diameter with a spiral corrugated surface with a slant angle of 15-30 degrees, which increases contacting time of air and water on the surface and makes the PRSF more rigid and stronger. The material used for fabricating the plastic rod is polystyrene, polypropylene, or polyethylene which have excellent physical and chemical properties. The technical effects of the invention make it suitable for replacing the existing fabrication of PrSFs which are currently being used in manufacturing lines.

Problems solved by technology

By using such manufacturing lines of two step manufacturing, the mass production of SSFs are accomplished, but high manufacturing cost cannot be eluded.

Embodiment Construction

[0071]The string screen fills (SSFs) invented by the present inventor have a disadvantage in manufacturing of the SSFs, since they are fabricated through separated two manufacturing lines of molding fabrication of SSF frame and webbing fabrication of winding strings over the SSF frame. Such manufacturing lines have a problem limiting more reduction of the manufacturing cost of SSFs. To complement such a problem, a one step manufacturing line, described above, of the present invention is invented. One step manufacturing means a manufacturing of SSF frame and string winding over the frame within one manufacturing line at a same time instead of individual fabrication through two different manufacturing lines, In other word, the SSF frame and loading string on the frame are completely accomplished in one step same manufacturing. Therefore, one step manufacturing line can reduce by nearly one half of manufacturing time and cost required in the previous manufacturing process claimed in US...

Abstract

The present invention involves plastic-rod-screen-fills for use as fill media in any evaporative water cooling and airborne fumes removal apparatuses. The plastic-rod-screen-fill consists of top and bottom frames and several plastic rods suspending from between the top and bottom frames in the shape of a rectangular thin plate as a rod screen. The plastic rods are separated sufficiently apart from each other in one layer and parallel to the length of the rectangular plastic-rod-screen-fill. The plastic rods and top and bottom frames are in one structure. Plastic-rod-screen-fills are assembled by adjoining to each other to fabricate the plastic-rod-screen-fills pack and designed to be installed upright or slantly in the evaporative cooling apparatuses. The plastic-rod-screen-fills have high manufacturing and installation cost competition, compared with those of current film fills and string-screen-fills. The fabrication methods of plastic-rod-screen-fills and plastic-rod-screen fill packs are described in the present invention.
