Abstract: A motor vehicle heat exchanger includes multiple first flow channels of a coolant medium arranged one over another, second flow channels of a process medium arranged between the first flow channels and provided at their ends with collection boxes, multiple sensors for detecting operating parameters and elongations of the heat exchanger and also a memory are arranged on and/or in the heat exchanger. Status monitoring of the heat exchanger involves obtaining measure values of an operating parameter from the sensors and storing the measured values in the memory. Characteristic values of the heat exchanger and the measured values stored in the memory are loaded into an analysis unit. The analysis unit, using analysis software, analyzes the measured values. An updated damage value of the heat exchanger is calculated and then stored in the memory and output.

Abstract: A heat exchanger system includes a fluid distribution element and a 1 pass heat exchanger. The fluid distribution element has a central inlet and fluid-sealed, channel-like fluid guide which branches into a plurality of fluid guidance channels. The 1 pass heat exchanger consists of a plurality of through-flowable tubes disposed in one plane and having planar partial faces, preferably flat tubes, and fins connected on the planar partial faces to the tubes. Each of the through-flowable tubes has a tube inlet and a tube outlet, the tube outlets opening into a fluid collection system. The fluid distribution element having the same number of fluid outlets as the 1 pass heat exchanger has through-flowable tubes and at least one of a direct connection of the fluid distribution element to the 1 pass heat exchanger or an indirect connection of the fluid distribution element to the 1 pass heat exchanger.
