Plate-fin heat exchanger.

摘要

A plate-fin heat exchanger having two fluid channels (A,B). The first fluid channel (A) is defined by two flat plates (2) opposed to each other at a specified spacing, and a first channel forming member (3) interposed between the flat plates (2). The channel forming member (3) is in the form of an aluminum extrudate comprising a pair of right and left spacing side walls (5) and a hollow connecting wall (4) interconnecting the side walls (5) and wavelike in the cross section of at least one of its upper and lower surfaces (4a). The second fluid channel (B) is defined by two flat plates (2) opposed to each other at a specified spacing, a pair of spacing side wall portions (10) provided therebetween and a fin member (11) positioned between the side wall portions (10).
