ABSTRACT:
A stack type heat exchanger which comprises a plurality of tubular elements including a tank section at least at one end, the tubular elements being adapted to allow a heat exchange medium to pass through; a plurality of air paths interposed between one tubular element and the next, each of the air paths being provided with a fin member; wherein each tubular element comprises a pair of metal tray members jointed at their peripheries with an inner plate interposed therebetween; wherein each inner plate is provided with projections on its top surfaces and undersurface so that the flows of the medium are blocked by the projections so as to enlarge the effective area for heat transfer between the medium and the tubular element.
