Wettable media and method of making the same

A wettable media pad, comprising:

• an inlet side and an outlet side, and
• a porous structure made from a non-woven material, comprising a plurality of channels having a hexagonal cross-section defined by six walls, the channels running from the inlet side to the outlet side;
• wherein the wettable media pad is configured to direct fluid from a top surface of the media pad to a bottom surface of the media pad along at least one of the walls of the channels;
• and
• wherein the wettable media pad is configured to exchange heat and mass between a fluid positioned on or in at least one of the walls of the channels and a gas flowing through the channels as the gas flows from the inlet side to the outlet side of the media pad;
• wherein at least one surface of the media pad comprises nanoparticles or quasiparticles.

• a porous structure made from a non-woven material, comprising a plurality of channels having a hexagonal cross-section defined by six walls, the channels running from the inlet side to the outlet side;
• and
• at least one ribbon of a second material running from a first surface of the media pad to a second surface of the media pad, configured to stiffen the media pad along an axis defined by the ribbon;
• wherein the wettable media pad is configured to direct fluid from a top surface of the media pad to a bottom surface of the media pad along at least one of the walls of the channels;
• and
• wherein the wettable media pad is configured to exchange heat and mass between a fluid positioned on or in at least one of the walls of the channels and a gas flowing through the channels as the gas flows from the inlet side to the outlet side of the media pad.
