After the trapezoidal holes are blocked, the sealing performance is good, air leakage is avoided, and the cooling efficiency is correspondingly improved; the rainwater pipe adopts the PVC material, and the low price practices thrift engineering cost than the drainage mode that adopts steel sheet eaves gutter, has compromise suitability and economic nature. The end baffle with the height of 80mm is arranged at the tail end of the profiled steel sheet connected with the tower body, and the end is watertight and air-tight (the other broadened platforms for spreading the profiled steel sheet cannot be provided with the end baffle because water is drained, and the end is watertight and air-tight).
