    摘要： A heat exchanger comprising a stack of sets of fins and tubes assembled to embossed plates with a void. The fins overlap the void having a peripheral margin of the fin attached to a peripheral margin on the plate around the void. Further provided are fins comprising through fluid apertures. Further provided are plates comprising lateral peripheral protrusions enabling selective sealing of gaps between adjacent plates. Also disclosed are plates comprising uniformizing protrusions configured to reduce non-uniform fluid mass flow between different channel protrusions in heat exchanging zones.
    Further discloses is an assembly method comprising alternately placing fins and plates or pre-assembled fin and plate sets, and a method for selective sealing faces of the heat exchanger by unselective application of sealant or heat. Also disclosed is a refrigerating apparatus comprising the heat exchanger of the invention having airflow exiting the heat exchanger pass through a condenser or evaporator.
