一个薄片叠层具有多个填充片，所述填充片具有一种有序排列的脊部和沟槽，所述脊部和沟槽在一个填充片的正面和反面上在一个平面上方延伸，所述填充片在一个组装状态下使为相邻填充片的相对正面和反面的脊部和沟槽提供了一种排列方式，这种排列方式提供了在相邻填充片之间的多个气流通道，所述脊部和沟槽的这种有序排列使气流以螺旋流动方式流经所述通道，从而提高了热交换能力，所述填充片还包括一种间隔装置，该装置以最小的薄片与薄片间的位移在至少两个边缘上形成相邻薄片的紧凑嵌套，以用于紧凑的装卸、运输和储存，同时在薄片叠层的装配过程中形成相邻填充片的自动间隔。 A film fill-pack has a plurality of fill-sheets with an ordered array of ridges and grooves 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 between adjacent fill-sheets for gas flow therethrough and where the ordered arrangement of ridges and grooves induces spiraling of the gas flow through the channels for promotion of improved heat transfer; and, where the fill-sheets further include a spacing arrangement 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.
