The invention relates to a heat exchanger for an air-conditioning system. The heat exchanger comprises multiple PTC heaters (2) for heating the air (LS) conducted through the heat exchanger (1). The PTC heaters are arranged at a distance from one another, so that the intermediate spaces (3) that are present in each case between two adjacent PTC heaters (2) form an air path (10) through which the air (LS) can flow. Here, at least one PTC heater (2) comprises a tubular body (5) with two longitudinal walls (8a, 8b) extending along a longitudinal direction. In the tubular body (5), a plurality of PTC heating elements (7) is arranged next to one another along the longitudinal direction (L). Here, the PTC heating elements (7) are arranged at a shorter distance (a1) from a first longitudinal wall (8a) of the tubular body (5) than from a second longitudinal wall (8b) located opposite the first longitudinal wall (8a).The heat exchanger according to the invention allows a particularly homogenous temporal temperature control of air.
