The invention discloses a combined cooling tower. The combined cooling tower mainly comprises a water tank, a spraying pump, smooth tube bundles, a filler, a spray nozzle, a water baffle, fin tube bundles and an induced draft fan. Air outside the tower enters the cooling tower from a blind window at the bottom, passes through the smooth tube bundles, a filler section and the fin tube bundles sequentially from bottom to top and is discharged to surroundings by the induced draft fan at the top after heat is carried away. High temperature fluids firstly pass through the fin tube bundles to be pre-cooled from top to bottom, then enter the smooth tube bundles to be subjected to evaporative cooling and flow out of the cooling tower after being cooled to required temperature. Depressing angles of the blind window are arranged in positions of four sides of a wall surface of a box body below the fin tube bundles so that air can enter and be mixed with the air which enters from the blind window at the bottom and then moves upwards for cooling high temperature water in the fin tube bundles, and corrosion of fin tubes is delayed while the cooling efficiency is increased. The filler section is arranged for evaporative cooling, the contact area of air and sprayed water is increased, heat exchange time is prolonged, and heat exchange efficiency is increased. The temperature difference of the combined cooling tower is greater than that of a common cooling device during cooling of high temperature water, energy saving performance and water saving performance are remarkable, the structure is compact, and usage is convenient.

The embodiment of the invention discloses a processing method for a bad branch circuit of a track circuit.
