The invention relates to a collector of liquid that includes a first layer (1) and a third layer (3), each of which includes a respective set of openings (6′) and (6″); a second layer (2), located on top of the first layer (1) and under the third layer (3), wherein collection of liquid to be generated and maintained at all times. A fourth layer (4), located immediately above the third layer (3), includes a material that absorbs by capillarity. The vacuum tube (7) included in the second layer (2) evacuates the liquid coming from the first layer (1) and the third layer (3), wherein said third layer (3) receives the liquid after it is absorbed by the fourth layer (4) and distributed uniformly on said fourth layer (4) by means of the material that absorbs by capillarity.
