Zusammenfassung:	The utility model provides a double-coil-pipe cooling device which is high in reliability. The double-coil-pipe cooling device comprises a cooling tank. Two cooling coil pipes are arranged in the cooling tank. One end of each cooling coil pipe is connected with a water inlet pipe, and the other end of each cooling coil pipe is connected with a water outlet pipe. One end of each cooling coil pipe is connected with a water flow indicator. The two ends of each cooling coil pipe are each provided with a valve for allowing water to flow through or cutting off water. The water inlet pipe and the water outlet pipe are connected with a reversing valve capable of switching the water inlet direction and the water outlet direction. Reverse water flow can clean the cooling coil pipes when led into the cooling coil pipes. The two cooling coil pipes are arranged, one can still work if the other is blocked and fails, and therefore unceasing production is ensured; the two ends of each cooling coil pipe are each provided with
