OG exemplary drawing
 
1. An evaporative cooling unit, comprising:
a first V-shaped portion of a winding of microporous hollow fibers configured for liquid transmission;
a second V-shaped portion of the winding of microporous hollow fibers configured for liquid transmission, wherein the first V-shaped portion is fluidly coupled with the second V-shaped portion to form a closed-loop rhombus shape; and
an internal cavity disposed between the first V-shaped portion and the second V-shaped portion.
 
6. An evaporative cooling unit, comprising:
a sheet forming a closed-loop shape comprising a rhombus or rhomboid; and
a plurality of microporous hollow fibers contained within the sheet, each microporous hollow fiber of the plurality of microporous hollow fibers comprising:
a wall system including one or more walls;
a liquid flow path defined by the wall system and configured to receive a liquid; and
a plurality of pores extending through the wall system, wherein the plurality of pores is configured to block passage of the liquid therethrough and enable passage of a vapor formed from the liquid therethrough.
 
11. An evaporative cooling unit comprising a winding of a plurality of microporous hollow fibers forming a closed-loop rhombus shape having a leading edge, a trailing edge configured to be disposed downstream of the leading edge relative to an air flow, and an internal cavity disposed between the leading edge and the trailing edge and having a boundary defined by the closed-loop rhombus shape.
