<p>A modular heat exchanger (10) includes unitary finned tubular core elements which can be assembled into a multi-module heat exchanger without any brazed or soldered connections or mechanical connectors. The modules (11) are preferably made from extruded aluminum blocks into which the heat exchanging fins (14) are cut or cold formed and into the ends of which flow accumulating passages (13) are bored or fluid accumulating tank connections are made. The modules are assembled with a high strength adhesive sealant which simultaneously secures the modules together and seals the peripheries of the bored passages at the module interfaces. Alternately, the modules are assembled with aluminum welds and accumulating end tanks similarly attached thereto with aluminum welds.</p> |
