An arrangement for de-icing a heat exchanger includes an air guiding housing and at least one fan. The air guiding housing is configured to take in an air from an outside of a motor vehicle through an inlet opening and to discharge the air from an outlet opening. The fan is positioned between the inlet opening and the outlet opening inside the air guiding housing and is configured to circulate the air in the air guiding housing. The heat exchanger is positioned between the inlet opening and the outlet opening inside the air guiding housing and allows the air to pass therethrough, thereby being configured to cool the air. The inlet opening and the outlet opening each are configured to be closed. The air guiding housing is configured to cause a circulation flow therein when the fan is operated while the inlet opening and the outlet opening are closed.
