According to one embodiment of the present invention, a hot-coil cooling apparatus comprises: a support unit for supporting a hot coil; a heat-exchange unit arranged within the support unit; and a pump unit connected to the heat-exchange unit in order to supply coolant to the heat-exchange unit. Accordingly, the hot-coil cooling apparatus according to one embodiment of the present invention is configured such that the pump unit supplies coolant to a plurality of heat-exchange pipes of the heat-exchange unit, wherein constant pressure is applied to the coolant, such that a large amount of coolant flows to a high-temperature heat-exchange pipe having low viscous resistance, and the temperature difference between a high-temperature point and a low-temperature point of the hot coil decreases, thereby rendering the temperature distribution of the hot coil uniform. |
