PURPOSE: An evaporator comprising an inner-fin tube is provided to increase heat exchange efficiency by making liquid refrigerant flow in a circle shape since inner fins are formed in a refrigerant tube. CONSTITUTION: An evaporator comprising an inner-fin tube comprises a refrigerant tube(100), a plurality of outer fins and a plurality of inner fins(120). While flowing in the refrigerant tube, refrigerant exchanges heat with air. The outer fins are formed on the outer surface of the refrigerant tube. The inner fins are formed on the inner surface of the refrigerant tube, guides the refrigerant along the inner circumferential surface of the refrigerant tube and prevents the refrigerant from becoming discharged to the outside of the refrigerant tube without evaporation. The inner fins are protruded to the inner side of the refrigerant tube. |
