The invention belongs to the field of heat exchange equipment, and especially relates to an open type cooling tower used for preventing fog formation at air outlets. The crossfolw open type cooling tower is capable of reducing or avoiding fog formation at air outlets during operational processes in winter. The crossfolw open type cooling tower comprises a tower body (1), an air duct (11), and a draught fan (2); two water dispersing tanks (3) and a water collection tank (4) are arranged in the tower body; the water dispersing tanks are provided with a plurality of columns (31) protruding upward; each column is provided with a spraying water inlet (311) and a spraying channel extending to the bottom of the corresponding water dispersing tank; the plurality of columns are arranged in a plurality of lines, and the height of the spraying water inlets of a few lines of columns is lower than the height of the spraying water inlets of the rest lines of columns; a plurality of filler sheets (5) are arranged in lines successively in the tower body at intervals; and the lines of columns are arranged right above the intervals.
