Abstract

A heat exchanger may include a first collecting tank and a second collecting tank. The first collecting tank may include a first collecting pipe having a first collecting pipe opening for letting in a fluid and a second collecting pipe having a second collecting pipe opening for discharging the fluid. The second collecting tank may be arranged opposite the first collecting tank and may include a third collecting pipe and a fourth collecting pipe. The heat exchanger may also include a plurality of heat exchanger pipes fluidically connecting the first collecting pipe to the third collecting pipe and the second collecting pipe to the fourth collecting pipe. The heat exchanger may also include a separating wall arranged in each of the first collecting pipe and the second collecting pipe respectively dividing each into a first pipe section and a second pipe section.
