(54) Heat exchanger for improving thermal efficiency and air conditioner mounted therewith


(57) A heat exchanger of an air conditioner is disclosed whereby refrigerant is not biased to a particular heat exchange line but evenly flows in all the heat exchange lines. The heat exchanger comprises: a housing (51) having air inlets (51a,51b,51c) and an air outlet (51d); and a plurality of heat exchange lines (52,53) each formed inside the housing (51) in a serpentine shape for refrigerant to flow and switch the flow direction, and wherein the plurality of heat exchange lines (52,53) are arranged in such a manner that each line crosses each other before and after the infusion directions of air introduced via the air inlets.
