A multiple tube bundle heat exchanger includes axially opposite tube plates, a housing, and a plurality of tube bundles disposed between the tube plates. Each of the tube bundles is an independent tube bundle subassembly forming an integral unit having at least one heat exchanger tube with two axial tube ends. The subassembly is made from the exchanger tube and respective tube plates fastened to the two axial tube ends. The housing has a casing part defining a interior and having two axial housing end with flanges, removable head pieces respectively disposed at the too axial housing ends to be fastened to the flanges, and partitions subdividing the interior into chambers. The number of chambers corresponds to a number of tube bundles. Each of the chambers receives one of the tube bundles. The tube plates and head pieces respectively form seals, and the tube plates delimit distributor, collecting, and/or transfer chambers formed in the head pieces.
