PURPOSE: To accelerate heat transfer while suppressing loss of a cooling fluid by arranging a large number of filmy filling sheets contiguously in the vertical direction as a filling sheet bundle and creating spiral motion of gas flow through protrusions and grooves arranged on the surface and rear of the filling sheet. CONSTITUTION: A film fill-pack(12) has a plurality of fill-sheets(14,50,52,58,60) with an ordered array of ridges(163) and grooves(165) generally extending above a planar surface on both the obverse and reverse surfaces of a fill-sheet, which fill-sheets at an assembled state provide the ridges and grooves of facing obverse and reverse surfaces of adjacent fill-sheets in an arrangement providing a plurality of channels(220,222) between adjacent fill-sheets for gas flow therethrough and where the ordered arrangement of ridges(163) and grooves(165) induces spiraling of the gas flow through the channels(220,222) for promotion of improved heat transfer; and, where the fill-sheets(14,50,52,58,60) further include a spacing arrangement(252) providing a compact nesting of adjacent sheets with minimal sheet-to-sheet displacement at least at two of the edges for compact handling, transfer and storage with a self-spacing of adjacent fill-sheets at assembly of the film fill-pack. |
