Claim:
1. A refrigerator, comprising: a compressor configured to compress a refrigerant; a condenser configured to condense the refrigerant being introduced from the compressor; a capillary tube configured to expand the refrigerant being introduced from the condenser; an evaporator configured to evaporate the refrigerant being introduced from the capillary tube to absorb heat of a surrounding environment and to cool the surrounding environment; and a suction pipe configured to guide the refrigerant being discharged from the evaporator to the compressor, the suction pipe including wherein the capillary tube comprises a spiral portion disposed in a form of a spiral at an inside of the first pipe of the suction pipe, the spiral portion being in contact with both the first wall and the second wall of the first pipe and being spaced apart from the connecting wall of the first pipe, so as to directly exchange heat with the refrigerant at the inside of the suction pipe.
