Abstract

A heat exchanger (10) cooling a fluid and a method for manufacturing, the heat exchanger (10) having an outer pipe section (12) in which a plurality of inner pipe sections (36) with channels for the fluid to be cooled are disposed. At least one cooling fluid channel (56) is disposed in the outer pipe section (12). The at least one cooling fluid channel (56) and the at least one channel for the fluid to be cooled are in heat contact and fluidically separated from each other. A plurality of inner pipe sections (36) open on both ends (38, 46) form of a pipe bundle (34) having ends fixed tightly in a corresponding lead-through opening (40) of an upstream end body (42) and fixed tightly with the other end (46) in a corresponding lead-through opening (48) of a downstream end body (50).
