Product Details
Products Description
Evaporative Kraft Paper Honeycomb Cooling Pad:
The Cooling Pad is based on the natural physical phenomenon of “water evaporates and absorbs heat”, that is, water flows from top to bottom under the action of gravity, forming a water film on the corrugated fiber surface of the cooling pad. When the fast-moving air passes through the cooling pad, the water in the water film absorbs the heat in the air and evaporates, so that the temperature of the air passing through the cooling pad is reduced, thereby achieving a cooling effect.
