HEAT EXCHANGER AND AIR CONDITIONER HAVING THE SAME

摘要

PURPOSE: A heat exchanger and an air conditioning device comprising the same are provided to minimize pressure loss and maximize heat transfer performance, and reduce noise by making the fluid distribution of the inside and the end of a heat exchange fin uniform. CONSTITUTION: A heat exchanger comprises a plurality of refrigerant pipes and a flat-type heat exchange fin(30). The refrigerant pipes are arranged at regular intervals in a length direction. The heat exchange fin makes contact with the refrigerant pipe. The heat exchange fin comprises a guide protrusion(40). The guide protrusion is arranged between two refrigerant pipes. The guide protrusion comprises first slopes(41,42) and second slopes(43,44). The first slopes are respectively inclined upwardly along both sides based on the central line of the refrigerant pipes. The second slopes are respectively inclined downwardly from the upper ends of the first slopes. Louver units(60,70), which encourage the heat exchange of air flowing along the guide protrusion, are respectively formed on the first and second slopes.
