Abstract

Abstract Extended surface, fluid contact panels which include a plurality of tubular members in generally parallel relationship and spaced in a matrix of thin fins connecting the tubular members to create liquid-gas contact areas on the inside and outside surfaces of the tubular members and the fins. The tubular members and fin matrix are vertically oriented in staggered array with respect to the tower or structure in which the panels are used and in a preferred embodiment, the fins and tubes are tapered and shaped from a plastic material and selected ones of the fins are provided with projecting tabs and matching socket members for connecting the panels in end-to-end relationship and spaced rivet apertures are provided in the fins for accepting rivets to pin the panels in stacked configuration.
