The permutation structure is formed by the circular permutation of multiple rows of radiator-fan tube bundles which are vertically arranged in the periphery direction of an air-cooling tower. The row number of the air-cooling radiator radiator-fan tubes can be designed as 2 rows to 8 rows, each row of tubes is located on the circular arc with the center of the air-cooling tower as a circle center, and the radiator-fans are arc-shaped plates. The air-cooling radiator is divided into 6 or 8 cooling sections, and each section comprises a certain number of radiator-fan tube bundles and an up-and-down circulation water linkage tank. The water inlets and water outlets of the circulation water of the tube bundles inside the sections are converged to a circulation water distribution pipe, then are connected with a circulation water protopipe, and the circulation water flow controlling according to sections can be achieved.
