Beschreibung
Zusammenfassung:	A heat exchanger for heating a vehicle interior may include a heat exchanger block including a plurality of air ducts and a plurality of coolant ducts arranged according to a cross flow principle. The heat exchanger block may have a first heat exchanger stage including an air inlet side and a second heat exchanger stage including an air outlet side. The plurality of air ducts and the plurality of coolant ducts may extend through the heat exchanger block and may be coupled to one another in a heat-transferring and media-separated manner in both the first heat exchanger stage and the second heat exchanger stage. The heat exchanger may further include a plurality of thermoelectric modules, configured to operate as a heat pump to transfer heat from the coolant flow to the air flow, arranged between the plurality of air ducts and the plurality of coolant ducts.
