Condenser assembly structure

摘要

The condenser assembly structure is disclosed. The opening of the outgoing pipe is positioned below the upper openings of the heat transfer tubes in the inner space of the upper header pipe. Cutouts are formed in the upper ends of heat transfer tubes, which are located within an upper header pipe. A lubricant mixed in a refrigerant is introduced from the inside of the upper header pipe into the heat transfer tubes by way of the cutouts. The outgoing pipe defining is attached to the lower header pipe at a position close to its end. A total passage area of first heat transfer tubes through which the refrigerant flows downward is larger than that of second heat transfer tubes through which the refrigerant flows upward. The total passage area of the second heat transfer tubes is smaller than that of third heat transfer tubes through which the refrigerant flows downward.
