Technical Field
[0001] The utility model relates to the technical field of coolers, in particular to a circulating tailwater channel cooler. Background Art
[0002] After passing through the turbine, the water energy carried by the water flow is absorbed and utilized by the turbine and becomes tailwater. Tailwater refers to the water body produced in a specific production or treatment process that is no longer directly used.

However, during the use of existing coolers, the tail water will contain some impurities and the water temperature will be high. After a long period of operation, scale or condensation will easily form on the inner wall of the cooler tube, making it difficult to clean, affecting the normal use of the cooler.
