Zusammenfassung:	Device for cooling flat rolled material with a liquid coolant has at least one cooling bar, which is arranged above the conveying path and to which the liquid coolant is fed. A plurality of outlet tubes have, in a flow direction of the liquid coolant, an initial portion, which proceeds from the inlet opening and extends upward, a middle portion, which adjoins the initial portion, and an end portion, which adjoins the middle portion and extends downward and to the output opening. The middle portion contains a vertex at which the coolant flowing through the outlet tube in question reaches a highest point. The outlet openings are located above the cooling bar. A height distance (h1) of the inlet opening from the vertex is at least twice as large, in particular at least three times as large, as a height distance (h2) of the outlet opening from the vertex.
