PURPOSE: A radiating fin for refrigerator condenser and method for coupling radiating fins is provided to achieve an improved heat efficiency by attaching radiating fins with increased radiating surface, to the refrigerator condenser. CONSTITUTION: A radiating fin(10) shaped as a square has a plurality of holes(20) with a burring portion(30) and a slitting portion(40). The burring portion is tampered, and has an inlet portion with an inner diameter larger than the outer diameter of a refrigerant pipe. The burring portion has an outlet portion with an inner diameter smaller than the outer diameter of the refrigerant pipe. The slitting portion is formed at the side surface of the burring portion. A method for coupling radiating fins and a refrigerant pipe, comprises the steps of arranging the radiating fins in a single row, and rotating and inserting the refrigerant pipe to the hole formed at the radiating fin, in such a manner that the refrigerant pipe tightly contacts the burring portion formed at the hole.
