PURPOSE: An air conditioner heat exchanger is provided, in which a plurality of refrigerants are eliminated so as to prevent refrigerant heat from being transferred to a lower flat fin of the heat exchanger, to thereby improve heat exchange performance, while reducing power consumption by allowing air to smoothly pass through the refrigerant path. CONSTITUTION: A heat exchanger(200) comprises a plurality of flat fins(210) arranged at a constant spacing so as to allow the air to pass through flat fins; a plurality of refrigerant pipes(220) arranged at the side surface of the flat fin in such a manner that refrigerant pipes are inserted in perpendicular direction to the side surface of the flat fin so as to allow the refrigerant to flow through the refrigerant pipes; and a plurality of return pipes(240) connected at both ends of the refrigerant pipe in such a manner that refrigerant pipes form first to fourth refrigerant path groups(230,231,232,233) and has refrigerant inlet and outlet sides which are independent to each other. Two or more refrigerant pipes are eliminated so as to prevent dew formation, allow the air to smoothly pass and guide the flow of condensate water flowing in a gravity direction, thereby improving heat exchange performance.
