Abstract

L'invention concerne une structure de collecte d'un fluide évaporé. La structure peut comprendre un réservoir qui retient un liquide. Le réservoir peut avoir une extrémité ouverte et une enceinte montée autour de l'extrémité ouverte du réservoir de manière à piéger un fluide qui s'évapore du réservoir. L'enceinte peut comprendre une structure support et un recouvrement apte à être tendu et soutenu par la structure support. La structure peut également comprendre un collecteur qui collecte les condensats provenant du recouvrement, le collecteur étant monté sur la structure support, entre la structure support et le recouvrement, et orienté de manière à recevoir les condensats qui se déplacent par gravité le long du recouvrement. Un appareil tendeur peut être utilisé pour tendre le recouvrement autour du collecteur de manière à encourager les condensats à s'engager sur le collecteur. Les condensats peuvent alors être transportés à l'intérieur du collecteur jusqu'à un emplacement souhaité.
