The present invention relates to the technical field of aero-engines, and provides a supercritical carbon dioxide compressor. The supercritical carbon dioxide compressor comprises a shell assembly, an air inlet and exhaust assembly, and a rotor assembly. A supercritical carbon dioxide working medium circulating in a first circulating assembly expands, and a supercritical carbon dioxide working medium circulating in a second circulating assembly is compressed. A width angle α3 of a first air inlet pipe ranges from 40° to 50°, a width angle α4 of a first exhaust pipe ranges from 60° to 70°, a width angle α1 of a second air inlet pipe ranges from 55° to 65°, and a width angle α2 of a second exhaust pipe ranges from 30° to 40°. The rotor assembly comprises a drum. A plurality of working medium channels which are not communicated are arranged in the drum, and the drum is rotatably provided in a closed space, so that each working medium channel is periodically communicated with the air inlet and exhaust assembly.
