Abstract:
A heat exchanger block comprising:a plurality of tube block units positioned one behind the other in a block depth direction from a front to a back of the heat exchanger block, each said tube block unit including a plurality of tube units stacked one above the other in a block height direction from a bottom to a top of the heat exchanger block, said tube units each having a plurality of flow ducts extending transverse to said block depth and height directions and being fluid flow connected at at least one end to at least two collector ducts extending in said block height direction; at least one collector-duct connection extending between at least two adjacent ones of said block units, said one collector-duct connection fluid flow connecting one of said collector ducts of one of said two adjacent block units directly to one of said collector ducts of another of said two adjacent block units; and at least one collector-duct connection extending between each other pair of adjacent ones of said block units to provide a series fluid flow path through said block units.
