Abstract
A film-type packing element (1) for use in a cooling tower comprises a formable sheet material formed with corrugations (3) and ridge formations (5) extending obliquely of the direction of the corrugations (3) to provide deflection channels for fluid descending over the packing element. The ridge formations (5) are divided into a plurality of groups (9) along the corrugation direction, with the ridge formations (5) of successive groups (9) being angled oppositely relative to the corrugation direction.
Claims28
A film flow packing element for use in a cooling tower comprising a formable sheet material formed with corrugations and ridge formations extending obliquely of a direction parallel to a line along a peak of the corrugations to provide deflection channels for fluid descending over the packing element, the ridge formations being divided into a plurality of groups along said direction with the ridge formations of successive groups being angled oppositely relative to said direction, wherein the ridge formations extend over less than a pitch of the corrugations between a peak and a neighboring trough thereof.
A film flow packing element for use in a cooling tower comprising a formable sheet material formed with corrugations and ridge formations extending obliquely of the direction parallel to a line along a peak of the corrugations to provide deflection channels for fluid descending over the packing element, the ridge formations being divided into a plurality of groups along said direction with the ridge formations of successive groups being angled oppositely relative to said direction, wherein the ridge formations are formed to provide a zig-zag pattern transverse to said direction with each peak or trough of the zig-zag substantially coinciding with a peak or trough of said corrugation.
A film flow packing element for use in a cooling tower comprising a formable sheet material formed with corrugations and having discrete stand-off formations upstanding along ridge lines of the corrugations on one face of the sheet and discrete socket formations formed along other ridge lines of the corrugations on the other face of said sheet, and positioned so as to engage each other when alternate sheets are rotated substantially 180.degree. in the plane of said sheets, said socket and stand-off formations being sized so that when the stand-off formations of one sheet engages the socket formations of an adjacent sheet, the ridge lines on which those socket and stand-off formations are formed are maintained in spaced relationship.
A film flow packing element for use in a cooling tower comprising a formable sheet material formed with corrugations and having discrete stand-off formations upstanding along ridge lines of the corrugations on one face of the sheet and discrete socket formations formed along other ridge lines of the corrugations on the other face of said sheet, and positioned so as to engage each other when alternate sheets are rotated substantially 180.degree. in the plane of said sheets, wherein edges of the sheet parallel to said ridge lines are formed between a peak and a trough of said corrugations wherein opposed edges neighbor a trough and a peak respectively.
