1. A device for exchanging thermal energy with ambient air, the device comprising:
a plurality of heat exchangers through which an air flow flows, each of the heat exchangers being assigned an axial fan and an outflow housing;
the axial fan being configured to convey the air flow through the heat exchangers, respectively, the axial fan having a motor and an impeller wheel with a blade which is driven by the motor to rotate about an axis of rotation; and
the outflow housing being configured to receive the air flow conveyed by the axial fan on an outflow side of the axial fan, respectively, the outflow housing forms an air intake chamber axially offset from the impeller wheel and the motor of the axial fan, which receives the conveyed air flow over an entire cross-section of the impeller wheel and the motor and is penetrated by the axis of rotation, the outflow housing, in a rear view, covers the impeller wheel and the motor as a hood, and is configured to supply the conveyed air flow to an air outlet opening of the outlet housing with a directional component tangential to a swirling movement imposed on the air flow by the axial fan; and
a common air outlet channel configured to receive the air flows conveyed by the axial fan from the air outlet opening of the outflow housing from each of the heat exchangers, the common air outlet channel being configured to discharge the air flow to the environment;
wherein the air outlet opening of the outflow housing of each of the heat exchangers are aligned obliquely to one another.
