Scroll compressor

The utility model discloses a scroll compressor which comprises a rack, a motor assembly and a scroll assembly, the motor assembly and the scroll assembly are installed on the rack, the motor assembly is in transmission fit with the scroll assembly through a motor shaft, an air flow channel is formed in the rack, and the air flow channel is sequentially provided with an air inlet section, a heat exchange area and an exhaust section along an air flow path. A balance block is assembled at the position, stretching into the heat exchange area, of the motor shaft, and the balance block is provided with blades which are driven by the motor shaft to rotate to disturb air so that the air can at least circulate along the air inlet section, the heat exchange area and the air outlet section. According to the scheme, on the premise that the original installation mode and precision of the scroll compressor are kept unchanged, the eccentric balance effect of the crankshaft is achieved, the overall heat dissipation efficien
