<p>The utility model relates to a heat exchanger and an air conditioner, which can improve the heat transfer performance under the circumstance that the ventilation resistance is not greatly increased. The heat exchanger comprises a plurality of fins (30), heat transfer tubes (40) and incising slices (33), wherein the fins (30) are provided with specified air gaps which are arranged in parallel and the heat exchange air flows in the gaps of the fins (30); the fins (30) penetrate through the heat transfer tubes (40) in the direction orthogonally crossed with the flow direction (F) of the heat exchange air between the fins (30), the heat transfer tubes (40) are close to each other and refrigerant for conduction is filled in the heat transfer tubes (40); and each incising slice (33) is arranged between two adjacent heat transfer tubes (40), the incising slices (33) are arranged at least within the area between the end edge (31a) of the air upstream side of the fins (30) and the centerline (C) connecting the centers of the heat transfer tubes (40) together, and the width of the incising slices (33) in the flow direction of the heat exchange air is above one second of the outer diameter (D) of the heat transfer tubes (40).</p> |
