The invention relates to a heat exchanger assembly, in particular for a vehicle heating device, comprising a pot-like inner heat exchanger housing (12) having a first bottom wall (16) and a first circumferential wall (18) that is connected to the first bottom wall (16) and surrounds a longitudinal axis (L), a pot-like outer heat exchanger housing (14) having a second bottom wall (20) and a second circumferential wall (22) that is connected to the second bottom wall (20) and surrounds the longitudinal axis (L), a fluid flow space (24) formed between the inner heat exchanger housing (12) and the outer heat exchanger housing (14), a first flow guiding formation (40) that extends substantially in the direction of the longitudinal axis (L) along the first circumferential wall (18) and the second circumferential wall (22) and a second flow guiding formation (42) that extends substantially in the direction of the longitudinal axis (L) along the first circumferential wall (18) and the second circumferential wall (22) at a circumferential distance from the first flow guiding formation (40), which first flow guiding formation (40) and second flow guiding formation (42) divide the part (28) of the fluid flow space (24) formed between the first circumferential wall (18) and the second circumferential wall (22) into a first partial flow space (44) and a second partial flow space (46), at least one fluid inlet opening (49) open to the first partial flow space (44) and at least one fluid outlet opening (51) open to the second partial flow space (46), a press fit formation (94) for fixing the inner heat exchanger housing (12) in relation to the outer heat exchanger housing (14), is characterized in that the press fit formation (94) comprises the first flow guiding formation (40) and the second flow guiding formation (42) and/or that the press fit formation (94) is provided in an end region (32) of the circumferential walls (18, 22) lying at a distance from the first bottom wall (16) and the second bottom wall (20).
