The invention relates to a heat exchanger (1), particularly such as a charge air cooler or exhaust gas cooler, having a pipe-pipe base assembly (2), in which pipes (5) are inserted in a sealed manner with their opposite pipe ends into openings in two opposing pipe bases (3, 4), wherein between the two pipe bases (3, 4) at least one partial region of a housing (8) is disposed which engages around the pipes (5) of the assembly (2) and seals it from the outside, wherein the two pipe bases (3, 4) have two sides extending in parallel to each other and each adjoining an end region (6, 7) of the pipes (5), on which sides, on a side of a pipe base opposite the housing between the pipe bases, a further housing part (15, 16) is disposed in each case and is connected to the housing (8) in a sealed manner between the pipe bases, wherein on at least one of the pipe bases (3, 4) a seal (21, 22) is arranged in a sealing manner between the housing (8) and this pipe base (3, 4) and/or between this pipe base (3, 4) and the further housing part (15, 16), which is arranged on this pipe base (3, 4). |
