Trickler heat-exchange apparatus

摘要

The upper end portion of an upright tubular wall whose inner side is contacted by material requiring to be cooled, is surrounded by an annular receptacle for cooling water. An annular baffle extends from the receptacle towards but not into contact with the exterior of the wall; its free edge defines with the wall an annular gap. This gap is bridged by tufts of fibers which are arranged along the gap in one or more rows, so that water running from the receptacle over the baffle travels along the fibers whose free ends are in contact with the wall, and is applied to the wall of a film of uniform thickness.
