Abstract
A heat exchanger suitable for a vehicle includes a plurality of tubular first members arranged in a row and forming elongate gaps. These members form passageways for flow of a first fluid for heat exchange with cooling air flowing through the gaps. The first members and gaps form a primary heat exchange area. Inlet and outlet manifolds are connected to the first members for directing the first fluid through the first members. An associated cooling device circulates liquid coolant and comprises flat tube-like second members, each extending into a respective gap in a secondary area which is part of the primary area but smaller. The second members each have a thickness at least the width of their respective gaps. At least some of the first members can be formed with cut-outs in opposite flat sides, these cut-outs being sealingly closed by the second members.
