1. An accumulator comprising:
a cyclone having a spiral flow path through which a refrigerant flows;
a housing having an open end and accommodating the cyclone;
a cover coupled to the open end of the housing and having an inlet for introducing the refrigerant into the cyclone closer to an axial direction than a radial direction of the cyclone,
a separator accommodated in the housing and separating the refrigerant introduced from the cyclone into a gas phase and a liquid phase; and
a spiral tube accommodated in the housing and through which a medium for heat exchange with the refrigerant in the gas phase separated in the separator flows;
wherein the cyclone further comprises:
two separate, spiral flow paths, a first one of the flow paths leads the refrigerant from the inlet into an inside of the separator and radially outwards, and a second one of the flow paths leads the refrigerant from an end of the cyclone facing away from the cover into the spiral tube.
