Heat exchanger with increased compactness and pressure resistance

摘要

The exchanger has an extended body (3) in which rows of longitudinal channels (11, 15) are arranged, where a fluid is circulated in the channels. The channels are disposed on both sides of a third row of longitudinal channels (19) in which another fluid is circulated in order to permit heat exchange between the two fluids. The channels (11, 15) are shaped near one of their ends so as to be received in a same opening (23) provided in a manifold (5). The channels (19) are shaped near one of their ends so as to be received in an opening (20) provided in a manifold (7).
