PURPOSE: To provide a device for cooling hot rolled wire rod, which is equipped with a heat reflection plate so that cooling rate of wire rod coil is uniformly maintained by the heat reflection plate using a retarded Stelmor cooling method. CONSTITUTION: In a cooling device for retarded cooling a wire rod coil coiled by a coiler after a wire rod is rapidly cooled, the device for cooling hot rolled wire rod comprises a conveyor which moves the wire rod coil and is equipped with a cover(30); and a heat reflection plate(40) which is installed at the inner side of the cover, and on left and right portions of which a downward inclined part(42) is formed, wherein a ratio(Wref/Wrod) of width of the heat reflection plate to width of the wire rod coil is 0.88 to 0.93, wherein a ratio of width(We) of the inclined part to the total width(Wref) of the heat reflection plate is 0.021 to 0.024, and wherein an inclination angle(α) of the inclination part is 25 to 30 degrees.
