Abstract:
A Heat-exchange module of the type comprising a first heat exchanger having a core mounted between two manifold chambers, onto which core is assembled a second heat exchanger having a core mounted between two manifold chambers, such that an airflow can pass over the first heat exchanger and said airflow can pass over the second heat exchanger, wherein in that the manifold chambers (18, 20) of the first heat exchanger (12) are each substantially formed from at least two shaped sheet-metal pieces (36, 38) and each of the manifold chambers of the first heat exchanger (12) comprise at least one lug (52, 64) integrally formed as a homogenous body with at least one of the sheet-metal pieces and folded into a housing (60, 68) of matching shape with each of the manifold chambers (28, 30) of the second heat exchanger (14);wherein said at least one lug is formed to overlap and at least partially wrap around a portion of each of the manifold chambers (28, 30) of the second heat exchanger (14).
