The utility model relates to a circulating water system for brake cooling of an intaglio printing press. The utility model aims at solving the technical problem that the provided system can realize the recycling and reusing of the cooling water on the premise of ensuring the normal work of the printer and also has the characteristics of saving the water resources, improving the cooling effect and reducing the operating cost. The provided technical scheme is as follows: the circulating water system for brake cooling of the intaglio printing press comprises a water inlet pipe and a water outlet pipe, wherein all brakes are accessed between the water inlet pipe and the water outlet pipe in parallel; the water outlet pipe is also communicated with a water reservoir so as to cause the back water in the water outlet pipe to flow in the water reservoir, the water inlet pipe is communicated with the water reservoir through a water pump so as to extract the water in the water reservoir as the water for cooling; and a filtering apparatus is arranged in the water reservoir to perform filtering to the back water in the water outlet pipe; and the water reservoir is also connected with a water inlet pipe provided with a valve to complement the water in the water reservoir.
