PROBLEM TO BE SOLVED: To provide an auxiliary cooler where cooling water does not remain in a nozzle or in the pipe near the nozzle when it has stopped. SOLUTION: For an auxiliary cooler 5, a power supply pipe 9 between a solenoid valve and a nozzle 7 is arranged at a downward gradient, and an electric air intake valve 10 is installed in the position above the water supply pipe 9, and the remaining water in the water supply pipe 9 is discharged completely. Moreover, a funnel-shaped drain receiver 11 provided on a nozzle frame 6 under a nozzle, a dish-shaped drain pan 13 provided at the bottom of a condenser, a tubular drain trough 12 connecting the drain receiver 11 with the drain pan 13 are installed to lead the remaining water discharged from the nozzle 7 to the drain pan 13. |
