摘要

The device for desalination of water by distillation, comprises an optical energy source with non-photovoltaic solar panels having a microscopic lens, a cavity or a borewell for recuperating the water, and an evaporator. The water is preheated naturally by the sun through a labyrinth channel and in a closed circuit conveyed towards the evaporator. The preheated water is boiled in a closed tank (3) sealed by the solar panel allowing to increase the solar energy efficiency and to accelerate the evaporation of saline water.
