The invention discloses a heat exchange reinforcement air conditioner. A heat exchanger comprises a heat exchange pipe. The heat exchange pipe comprises round pipe segments. The round pipe segments are connected with oval pipe segments through oval transition segments. All the round pipe segments are equal in length. All the oval pipe segments are equal in length. The cross angle of section oval long axes of every two adjacent oval pipe segments ranges from 15 degrees to 90 degrees. The cross section of the oval transition pipe segments is in the shape of a standard oval or the shape similar to an oval or the shape of a flat round formed by two straight lines and two arcs or the shape of a symmetric and approximately symmetric flat round or round formed by fitting a plurality of segments of arc lines. All the oval transition pipe segments are equal in length. Round pipe connector segments are arranged at the two ends of the heat exchange pipe. The inner walls of the round pipe connector segments are smooth. The inner diameter of the round pipe connector segments is equal to that of the round pipe segments. The heat exchange reinforcement air conditioner is simple in structure, balance of a speed field and a temperature gradient field is effectively and reasonably coordinated, and the energy saving and environment protecting efficiency is high.
