RETURN TUBE AND HEAT EXCHANGER COMPRISING THE SAME

摘要

A return tube and a heat exchanger including the same are provided to achieve the efficient heat exchange by performing the heat-exchanging between the refrigerant and an external fluid. A return tube(140) comprises a plurality of refrigerant flow paths. At least some of refrigerant flow paths are formed in the shape of an open curve having a preset radius of curvature. Inside them, refrigerant flows. A return tube connects end parts of adjacent tubes. The both ends of each tube pass through a plurality of pins. The return tube is bent in a pressed state.
