Abstract: A heat exchanger is provided for allowing heat to be exchanged between a first fluid and a second fluid, wherein the first fluid is a liquid. The heat exchanger comprises a core comprising: a plurality of first flow paths for the first fluid and a plurality of second flow paths for the second fluid; a plurality of pin components extending into the first flow paths; a plurality of fin components extending through the second flow paths; a plurality of first enclosure bars extending between adjacent separating plates that are either side of the first flow paths, the first enclosure bars being arranged to at least partially define the first flow paths; and a plurality of second enclosure bars extending between adjacent separating plates that are either side of the second flow paths, the second enclosure bars being arranged to at least partially define the second flow paths.

Abstract: A fin-plate heat exchanger is arranged to allow heat to be exchanged between a first fluid and a second fluid. The fin-plate heat exchanger comprises: a core with first flow paths for the first fluid and second flow paths for the second fluid; a plurality of separating plates; a plurality of fin components; a plurality of first enclosure bars; and a plurality of second enclosure bars. The heat exchanger further comprises a manifold arranged in fluid communication with each of the first flow paths of the core. The manifold and the core are formed as one integral piece, said integral piece comprising a stack of laminate members and said fin components. The plurality of laminate members comprise: first fluid enclosure structures each including a first manifold section.
