[0023] In one embodiment of the present application, as Figs. 1-4As shown, provide a modular cooling tower variable flow uniform water distribution device, including the main machine 1 and cooling tower body 2, the main machine 1 is connected with the water inlet pipe 11, the water inlet pipe 11 is communicated with the three-way pipe 12, the cooling tower body 2 is composed of several tower body 21, each tower body 21 is provided with fan 211, water tank 212, filler 213 and water tank 214, the fan 211 is arranged on the top of the filler 213, the water tank 212 is symmetrically arranged on both sides of the fan 211, and the two water outlets of the three-way pipe 12 are communicated with the water tank 212 on both sides of the fan 211, the bottom of the water tank 212 is communicated with the filler 213, the water tank 212 is provided with a first flow distribution plate 22 and a second flow distribution plate 23, the water tank 214 is arranged on the bottom of the filler 213, and the water tank 214 is communicated with each other.

[0024] Further, the first flow distribution plate 22 is distributed with a plurality of first water leakage holes 221, and the second flow distribution plate 23 is distributed with a plurality of second water leakage holes 231. The bottom of the second water leakage hole 231 is communicated with the water distribution nozzle 24. The edge of the first flow distribution plate 22 extends downwardly with a mounting portion, and the mounting portion is fixedly installed with the second flow distribution plate 23. Specifically, when the cooling water enters the water tank 212 through the three-way pipe 12, the cooling water can be spread over the first flow distribution plate 22 by controlling the flow rate, and the cooling water can flow downward to the second flow distribution plate 23 through the first water leakage hole 221 on the first flow distribution plate 22, and then the cooling water can flow downward to each water distribution nozzle 24 through the second water leakage hole 231 on the second flow distribution plate 23, and the cooling water can be sprayed to the filler 213 through the water distribution nozzle 24, so as to realize more uniform spraying effect.
