Cooling pad is a kind of special paper honeycomb structure material, its working principle is "water evaporation absorbs heat" , through the water under the action of gravity, from dirty, cooling pad in corrugated fiber paper surface water film formation, when air flows through the cooling pad of water film evaporation after water absorbs heat from the air, take away a lot of latent heat, Make the air temperature through the cooling pad lower, so as to achieve the purpose of cooling. Customized color according to customer requirements, performance is the same as brown
