Abstract

A heat exchanger (5) includes a housing (31), which contains a tube (32) and has a jacket (33), which surrounds the tube (32) while forming a ring channel (34). A primary inlet (35) and a primary outlet (36) are connected to one another fluidically via a primary path (37) carrying a primary medium through ring channel (34) and via a bypass path (38) carrying the primary medium through the tube (32). A control device (39) controls the flow of the primary medium through the primary path (37) and the bypass path (38). A secondary inlet (42) and a secondary outlet (43) are connected to one another fluidically via at least two secondary paths (44) for carrying a secondary medium. The primary path (37) is coupled with the secondary paths (44) in a heat-transferring manner with the media separated from one another.
