A coating element or coating layer (10; 100) is described, able to cool the coated space or the object it is in contact with, comprising a support means (22; 102), a sorption material (24; 104), contained between void spaces of the support means, able (i) to absorb and retain the water always in the liquid state, and (ii) to release it in the form of steam when heated; a second layer (40), superimposed to the first, equipped with channels (42) passing through its thickness, for the passage of water and steam to and from the first layer. The element or layer exhibits high efficiency in subtracting heat and is easy to build. |
