PURPOSE: A suction pipe assembly having a capillary tube wound in a spiral shape and a manufacturing method thereof are provided to improve heat exchange efficiency by increasing the contact area between a suction pipe and a capillary tube. CONSTITUTION: A suction pipe assembly having a capillary tube wound in a spiral shape comprises a suction pipe (100), a capillary tube (200), and a coupling unit. The suction pipe guides a refrigerant discharged from an evaporator to a compressor and has first and second circumference surfaces (111, 113). The second circumference surface is recessed inward from the first circumference surface and is formed in a spiral shape. The capillary tube guides the refrigerant discharged from a condenser to an evaporator and is coupled to the inner surface of the second circumference surface. The coupling unit couples the suction pipe and the capillary tubes to each other. |
