Abstract
A drift eliminator is formed from alternating curved spacers and corrugated spacer members to define tube-like passageways for the flow of air through an evaporative cooling apparatus. The formation of the corrugated blade member with beveled side walls places the back walls of the channels in a different plane than the front walls, with the lower edge of the front walls of the channels being positioned in a common plane along with the lower edge of the blade members. The angled side walls impede the formation of a film of water across the inlet opening into the channel, which requires an increase in horsepower for the fan to push air through the drift eliminator. Mechanical fastening devices molded into the respective members connects the corrugated spacer members and the blade members. A method of forming the corrugated spacer members to provide the angled side walls is also provided.
