Flow uniformizing device and coating equipment

The utility model discloses a flow uniformizing device and coating equipment. The flow uniformizing device is used for the coating equipment and comprises an outer pipe and an inner pipe, the outer pipe is provided with an outer air outlet; the inner pipe is arranged in the outer pipe, the inner pipe and the outer pipe are arranged in a spaced mode, the inner pipe is provided with an inner air outlet hole, and the inner air outlet hole and the outer air outlet hole are formed in the two sides of the central axis of the inner pipe respectively. According to the flow uniformizing device, the outer pipe and the inner pipe form a double-layer pipe structure, the buffering cavity is formed between the outer pipe and the inner pipe, gas is discharged at a constant speed, and loads in the pipes are reduced. Meanwhile, the inner gas outlet hole and the outer gas outlet hole are formed in the two sides of the central axis of the inner pipe correspondingly, so that gas flowing out of the inner gas outlet hole cannot di
