PURPOSE: An integral type dual tube evaporator of refrigerator is provided to improve heat exchange between air and refrigerant and fluidity of the air by expanding passage of cold air. CONSTITUTION: A pair of refrigerant pipes(52) in which refrigerant flows and a plurality of louver fins(56) formed between the refrigerant pipes are integrally formed. The refrigerant pipes and the louver fins are formed to be bent at a plurality of steps. Surfaces(56a) of the louver fins are installed parallel to flow of air flowing into an evaporator. A heater for defrosting is installed under the evaporator instead of a defrosting pipe formed between the refrigerant pipes as in an existing evaporator to extend distance between the refrigerant pipes and lengths of the louver fins.
