Compound corrugated direct evaporation foil

A compound corrugated direct evaporation foil adopts the structure that shadings (2) and support textures (3) are overprinted on the surface of a base foil (1) in the same direction, and the wavelengths of the support textures (3) are longer than that of the shadings (2). By adopting the direct evaporation foil, the flow rate of water is remarkably delayed and lowered, and the combination area and time of water and air are enlarged and prolonged, so that water can fully absorb heat in the air to achieve high-efficiency direct evaporation. The utility model has the advantages of long service life, no peculiar smell, simple and fast manufacture process, convenient installation and aesthetic appearance, demands less on water quality in use, and cannot influence evaporation efficiency after slight scale formation.
