ABSTRACT:
For fluid interchange treatment, a flexible collapsible structure is provided which consists of stacked horizontal partition walls formed from pairs of sheets of non-woven fabric material such as felt heat-joined by plastic coatings on their inner surfaces and disposed in vertically-spaced parallel arrangement and sealed at their sides by accordion-folded sheets of flexible collapsible material. The paired sheets contain ports which are offset relatively to one another in successive sheets. The paired fabric sheets and their plastic-coated inner surfaces are provided with openings to form cells with which the ports communicate, these openings being so arranged that, a multi-columned collapsible structure of parallel cellular formation results, with independent zigzag paths between top and the bottom of each cellular column. Thus, heat transfer is greatly enhanced by the retarded flow of the hot water horizontally across the liquid-absorbing fibrous surfaces of the felt on the exposed outer sides of the partition walls. The structure is preferably suspended from an external framework, the suspension causing the laminated partition walls to separate into parallel columns of laterally-interfitting vertically staggered cells.
