TITLE: GAS/LIQUID CONTACT DEVICE ABSTRACT A packing sheet for use in a device, e.g. a cooling tower wherein a film of liquid and a gas stream are brought into contact to effect heat exchange therebetween, the sheet being continuously corrugated to define a plurality of parallel depressions which are generally V-shaped in cross-section. Preferably the pair of walls which define each depression are disposed substantially at right angles with respect to one another and are disposed at an angle of around 45° with respect to the plane of the sheet. Preferably the sheet is formed with transverse ribs which project from the walls of the depressions and which extend substantially continuously between the depressions to form channels which communicate between the depressions. Advantageously the sheet is formed in the walls of the depressions with angled projections, which preferably extend continuously between two adjacent crests of the depressions. From another aspect the invention is a cooling tower pack for use in effecting contact between gas and a flowing liquid film, the pack comprising a plurality a packing sheets as described above assembled together to define a plurality of interconnected tubular cells each of which is of substantially rectangular cross-section, the arrangement being such that the adjacent sheets are in line contact with one another at intervals so that substantially the whole surface of the sheets is available for use in effecting the gas/liquid contact.
