An evaporative cooler comprises a housing having an upper surface and at least one vertical wall defining a chamber. The upper surface can include at least one opening in communication with the chamber. The evaporative cooler can also comprise at least one drain slit assembly for distributing a fluid and further comprise at least one screen. The screen can define a portion of the vertical wall. The screen can have an interior surface and an exterior surface relative to the chamber. In addition, the screen can be disposed relative to the drain slit assembly such that the drain slit assembly distributes the fluid over the screen. The screen can be configured such that the fluid forms a surface fluid layer over the surfaces of the screen. The evaporative cooler can further comprise an air conveyor disposed within the housing for drawing air through the opening and into the chamber such that the air is conveyed through the screen and the fluid layer.
