A noise-reducing and nonuniform tip clearance structure of centrifugal compressor is provided, which includes a compressor impeller body and a compressor impeller shroud. The compressor impeller shroud is circumferentially wrapped outside the compressor impeller body, and multiple impeller blade bodies are uniformly arranged in a circumferential direction of the compressor impeller body. A clearance between an impeller tip meridian line of the impeller blade body and an impeller shroud meridian line on the compressor impeller shroud is an impeller tip clearance. The impeller tip clearance gradually decreases in a direction from a leading edge to a trailing edge of the impeller blade body, and a change rate of the impeller tip clearance in the direction from the leading edge to the trailing edge of the impeller blade body also gradually decreases.
