Corrugated plate for plate type air coolers

The utility model relates to a corrugated plate for plate type air coolers. The corrugations of the corrugated area of a heat transfer plate include transverse corrugations formed by a plurality of minimum unit corrugation modules and longitudinal corrugations formed by a plurality of minimum unit corrugation modules, each minimum unit corrugation module consists of two strip-shaped convexes and two strip-shaped concaves, which have trough-shaped sections, the centers of the two strip-shaped convexes and the two strip-shaped concaves are formed into the four vertex angles of a rectangle, and both each row and each line are a strip-shaped convex and a strip-shaped concave. The utility model has the following advantages: (1) since the minimum unit corrugation modules are formed into the transverse and the longitudinal corrugations of the heat transfer plate, the corrugations, the strip-shaped concaves and the strip-shaped concaves are arranged crosswise, can constantly change the flowing direction of fluid, so
