HEAT EXCHANGER

摘要

A heat exchanger for a motor vehicle is provided having at least one block formed by tubes arranged parallel to one another and by fins arranged between the tubes. The tubes form multiple first flow ducts through which a first fluid can flow. The regions between the tubes form multiple second flow ducts through which a second fluid can flow around the tubes. The heat exchanger also has a first collecting box with a first fluid port and a second collecting box with a second fluid port. The first flow ducts are in fluid communication with a first cooling circuit via the first fluid port, the second fluid port, and the collecting boxes. The first collecting box or the second collecting box also has a third fluid port that, together with its respective collecting box and further fluid port, are in fluid communication with a second cooling circuit.
