The present application relates to the technical field of refrigeration devices, and discloses a heat dissipation structure for a compressor, comprising: a housing that defines a motor cavity having a liquid inlet through which a liquid-state refrigerant can enter the motor cavity; a motor that is located in the motor cavity, the motor comprising a rotor, and the rotor being rotatably located in the motor cavity; and blades that are provided on the rotor. When the rotor rotates, the rotor can drive the blades to rotate, and the blades then drive the liquid-state refrigerant in the motor cavity to flow, so as to cool the motor. The cooling effect of the refrigerant on the motor is increased, and all condition cooling of the compressor is implemented. The present application also discloses a compressor.
