Abstract
The application relates to a heat exchanger having a block with ribs and rectangular tubes. The block is arranged between a first collecting box and a second collecting box. Each collecting box is closed off by a base which has eyelets for receiving the tubes, and a trough-shaped circulating section for receiving the collecting box extends along the edge of the base. The base has an elevated contact region on at least one end face for the tube which lies directly opposite the end face in order to allow a stable structure of the heat exchanger, collecting boxes, and block.
