Fill pack assembly and method with bonded sheet pairs

摘要

A fill pack assembly and method for assembling a fill pack from individual sheets utilizes integrally bonded sheet pairs. Each sheet pair is a pair of two individual adjacent fill sheets which have been bonded together via any suitable bonding method. A plurality of the thus formed sheet pairs can then be attached together to form an entire fill pack or portion of a fill pack. Such fill packs are useful in heat exchange devices such as industrial cooling towers.

主权项

1. A method of assembling a fill pack from individual fill sheets, comprising:
integrally bonding two individual adjacent fill sheets, wherein each sheet has a perimeter and an internal contact point, wherein each contact point is one of a peak or a valley disposed within said perimeter and wherein each respective internal contact point engages the other contact point during assembly, to each other to form a bonded sheet pair; repeating the step of integrally bonding two individual adjacent fill sheets to each other to form more than one bonded sheet pair; and attaching two or more bonded sheet pairs to each other, wherein said step of integrally bonding two individual sheets comprises placing the two individual adjacent fill sheets between a pair of electrodes and radio frequency (RF) welding the individual sheets along the perimeter only at the respective peak or valley internal contact point of the respective individual sheet.
