Patent number: 7674304Abstract: 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.Type: GrantFiled: June 26, 2008Date of Patent: March 9, 2010Assignee: Brentwood Industries, Inc.Inventors: Timothy E.

Publication number: 20030150198Abstract: The present invention is directed to the separation of dust and debris from flowing fluid. Conventional cyclone separators and centrifugal separators present a tradeoff between the extent of dust separation and the cross-sectional area of fluid flow. Thus, increased flow capacity cannot be achieved without reducing the amount of dust removal. In contrast, the present invention allows for the increase of cross-sectional flow area without jeopardizing dust removal. The apparatus is designed such that the cross-sectional area of fluid flow can be increased independently of the radii of curvature of the redirections. Therefore, dust is still effectively removed while the flow capacity of the system is increased. Also included herein are embodiments utilizing these concepts of dust separation vacuum cleaner embodiments.Type: ApplicationFiled: February 19, 2003Publication date: August 14, 2003Inventors: Lewis Illingworth, David Reinfeld
