1. A flow disturbance apparatus, comprising:
a refrigerant pipe having a flow space in which refrigerant flows; and
at least one disturbance member disposed inside of the refrigerant pipe, wherein the at least one disturbance member is vibrated by a flow of refrigerant in the refrigerant pipe to disturb the refrigerant flowing in the refrigerant pipe, wherein a first end of the at least one disturbance member is a fixed end connected to an inner surface of the refrigerant pipe, and a second end of the at least one disturbance member is a free end positioned in the flow space of the refrigerant pipe, wherein the at least one disturbance member comprises:
a blade portion having a predetermined width; and
a connecting portion having a smaller width than the blade portion, wherein a boundary between the blade portion and the connecting portion includes a step, and wherein a length of the blade portion is greater than a length of the connecting portion, and wherein the connecting portion has a higher elasticity than the blade portion.
