A heat exchanger core includes a first sheet having a first side and a second side opposite to the first side, a second sheet opposing the first side of the first sheet, and a first fin extending between the first side of the first sheet and the second sheet. The first fin defines first channels that extend in a first direction, the first fin including a first slot that extends at a first angle between thirty degrees and sixty degrees from the first direction and fluidly connects at least two of the first channels together.

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.

A plate for a heat exchanger has a longitudinal centerline, a reference plane parallel to the longitudinal centerline, and multiple corrugations provided in the plate that define flow channels through which fluid flows. The corrugations extend at an angle to the reference plane and at least some of the corrugations are intersected by the reference plane, wherein over at least a portion of a surface area of the plate the corrugations are arranged in sub-regions that have a longitudinal length and the corrugations of each sub region are at the same angle relative to the longitudinal centerline, and the corrugations of adjacent sub-regions are at different angles from each other, and wherein the corrugations in adjacent sub-regions meet at junctions and the junctions are not longitudinally aligned.

A heat exchanger includes a plurality of cooling plates, a duct plate disposed around the cooling plates and a spacer plate fixed to both the duct plate and the cooling plate to prevent supercharged air from flowing into a gap between the duct plate and the cooling plate. The cooling plate includes cup portions allowing cooling water flow paths of the corresponding two cooling plates to be in communication with each other when the cooling plate is fixed to the adjacent cooling plate. The cooling water flow path formed in the cooling plate includes flow path portions and formed extending in a direction perpendicular to a flow direction of supercharged air from the corresponding cup portions. The cup portions are each formed in a tubular shape having a central axis at a position offset along the flow direction of the supercharged air from a center of the corresponding one of the flow path portions in a flow path width direction.

A thermal device according to the present disclosure includes a ceramic container, a fluid, and a sealing portion. The container includes an internal space, an opening portion connected to the internal space, and a communication path configured to connect the internal space and the opening portion. The fluid is located in the internal space. The sealing portion blocks the opening portion. The sealing portion includes a core portion and a flange connected to the core portion. The flange is bonded to the container around the opening portion. The core portion is located inside the opening portion. A portion of the core portion is in contact with the wall surface of the opening portion.

A heat exchanger comprises a stack of flat tubes defining first and second fluid flow passages, and a housing having side covers over the sides of the core, and being spaced from the sides of the core. The heat exchanger further comprises a bypass seal comprising a pair of side seals and a pair of clip members. The side seals are received between the sides of the core and the housing. Each side seal has an inner surface engaging the first side of the core and an outer surface engaging the first side wall of the housing. Each clip member has a middle portion to which a side seal is connected, as well as opposed first and second end portions which engage inwardly extending surfaces of the core.
