Abstract

A vehicle heater heat exchanger arrangement (10) includes: a pot-like heat exchanger housing (12) with a first bottom wall (18) in a first axial end area (16) and with a first circumferential wall (20) adjoining the first bottom wall and enclosing a longitudinal axis (L); and a pot-like outer heat exchanger housing (14) with a second bottom wall (22) in the first axial end area and with a second circumferential wall (24) adjoining the second bottom wall and enclosing the longitudinal axis. The inner heat exchanger housing and the outer heat exchanger housing are connected to one another in a second axial end area (26) and a fluid flow space (34) is formed between the inner heat exchanger housing and the outer heat exchanger housing. The second axial end area has an outwardly open recess (60) defined by the inner heat exchanger housing or/and by the outer heat exchanger housing.
