摘要

The doubled heat exchanger has a first core (110a) for effecting heat exchange between a first fluid and air and comprising several first small tubes (111) through which the first fluid flows. A first collection container (113,114) is arranged at the two longitudinal ends of each of the first small tubes, to which it is connected. A second core effects a heat exchange between a second fluid and air and has a number of second small tubes, through which the second fluid flows and which are arranged on a line in the direction of the air flow with the first core. A second collection container is arranged at the two longitudinal ends of each second small tube and is connected to them.
