1. A heat exchanger arrangement (WA) comprising
a housing (GE) in which an air inlet opening (ZO) is arranged on the circumference,
a cover (DE) that covers the housing (GE) on an upper side and in which an air outlet opening (AO) is arranged,
a reverse-operated radial fan (RL) being arranged inside the housing (GE) in such a way that it can generate an air flow between the air inlet opening (ZO) and the air outlet opening (AO), which air flow is directed radially inward with respect to the axis of rotation (RA) of said reverse-operated radial fan and which flows through at least one air heat exchanger (LT) arranged in the housing (GE),
wherein the air inlet opening (ZO) is arranged between the cover (DE) and the housing (GE), and
wherein the air flow generated by the reverse-operated radial fan flows upward through the air outlet opening (AO).
