Abstract
A fill sheet for cooling a working fluid flowing across the fill sheet with a gas flowing across a film of the working fluid includes a microstructure. The microstructure includes top ridges, bottom ridges and sidewalls connecting the top and bottom ridges. The top and bottom ridges defining a longitudinal axis. The microstructure also including rows of wavy peaks and valleys oriented at an acute micro-texture angle relative to the longitudinal axis. The rows of wavy micro-texture peaks and valleys defining a row axis. The rows of micro-texture peaks including alternating micro-texture apexes and micro-texture basins and the rows of micro-texture valleys including alternating micro-texture crests and micro-texture bases.
Claims17
A microstructure for a fill sheet for increasing airflow turbulence and working fluid film distribution, the microstructure comprising:
- micro-corrugations defined on the fill sheet, the micro-corrugations including a plurality of top ridges and a plurality of bottom ridges, the plurality of top ridges including a first top ridge and the plurality of bottom ridges including a first bottom ridge, the first top ridge and the first bottom ridge defining a first micro-corrugation band, the first micro-corrugation band extending from a first band end to a second band end, the first top ridge and the first bottom ridge defining a band height;
- and
- a plurality of micro-texture features on the micro-corrugations, the plurality of micro-texture features including a first micro-texture apex and a first micro-texture base on the first micro-corrugation band.
