摘要：
A heat exchanger for a refrigerator is disclosed, which has a simple structure, an improved heat exchanging efficiency, and an operating reliability. In the heat exchanger including a refrigerant tube (10) having a plurality of straight parts (11) and a plurality of curved parts (12) which connect the straight parts; and a plurality of fins (20) coupled to the straight parts (11) respectively through a plurality of inner through holes (21), the refrigrant tube (10) has a joining portion of the curved parts (12) and the straight parts (11) coated with a metal layer (110).
