The Cooling Pad is a kind of special paper honeycomb structure material. Its working principle is
the natural physical phenomenon of “water vapor absorbs heat”, that is, water flows from up to
down under the action of gravity, forming a water film on the corrugated fiber surface of the
Cooling Pad. When the flowing air passes through the Cooling Pad, the water in the water film
will evaporate and absorb the heat in the air, taking away a lot of latent heat, The temperature of
the air passing through the is reduced, so as to achieve the purpose of cooling.
