Abstract: A heat exchanger comprises a stack of sets of fins and tubes attached to or encompassed by embossed plates comprising a void. In some embodiments, the fins overlap the void having a peripheral margin of the fin attached to the peripheral margin around the void. In some embodiments, the fins comprise through fluid apertures allowing lateral fluid flow. In some embodiments, the plates comprise lateral peripheral protrusions enabling selective sealing of gaps between adjacent stacked plates by unselective application of heat or adhesive to a face of the heat exchanger. In some embodiments, the plates comprise uniformizing protrusions in a fluid inlet and/or outlet zone that reduce the amount of non-uniform fluid mass flow between different channel protrusions of heat exchanging zones of the set. Also disclosed are methods for assembly and selective sealing of the heat exchanger and an apparatus comprising the same.
