Heat exchanger for e.g. vehicle, with grid including parallel tubes and three connection headers, has single collection chamber with two groups of tubes connected to it

摘要

The second connection header (22) encloses a single collection chamber (220), to which both the first group of tubes (31) and the second group of tubes (32) are connected. Connection cross sections of both groups of tubes lie opposite each other in the second collection chamber (220). Associated tubes of the groups which lie opposite each other, have differing internal contours or are differently spaced from further tubes of the same group. Each group has tubes of differing cross sections. Tube distributions and flows may differ.
