A heat exchanger is disclosed. The heat exchanger includes a heat exchanger core including a stacked plurality of plates, a top plate, and a bottom plate. The plurality of plates includes two end portion plates, and a plurality of intermediate plates stacked between the end portion plates. Each of the plurality of intermediate plates has a flow-through portion penetrating through the intermediate plates through which a fluid flows. Each of the through holes of each of the plurality of intermediate plates demarcates a flowthrough path which penetrates through the intermediate plate in the stacking direction and is isolated from the flow path between plates. A boss portion having a substantially elliptical shape edge portion is formed at each plate.

A dual path heat exchanger integrated as a single unit able to process fluid stream through a continuous, single-use high temperature short time process. The heat exchanger contains both a heating section and a cooling section in the same unit. In one embodiment, the heating and cooling sections (which may be formed separately for other uses) are formed as a plate and frame structure with a thermally conductive thin film or foil forming the physical barrier between the process stream flow path and the thermal medium (heating or cooling) flow path. The film/foil renders the heat exchanger suitable for single-use and/or to be disposable. A manifold, which also may be formed as a single unit, may be used to transfer fluid flow between the sections of the heat exchanger, and/or to transfer fluid into and out of the system formed by the heat exchanger and manifold.

A heat exchanger may include a plurality of first core plates and second core plates stacked alternatingly, and a first flow path through which a first fluid may flow and a second flow path through which a second fluid may flow. The first flow path and the second flow path may be disposed between the plurality of first core plates and second core plates and alternatingly formed to be adjacent. A first passage hole may form a first flow-through portion at the first flow path and a second passage hole may form a second flow-through portion at the second flow path. The first flow path may be isolated from the second flow path. The first flow-through portion and the second flow-through portion may include an edge portion having an angle in a second direction perpendicular to flow paths. The core plates may include a boss portion that protrudes.

A heat exchanger may include a stacked plurality of plates and a fin plate brazed to each other. Each set of adj acent said plates of the plurality of the plates may define a flow path between plates. Each plurality of the plates may include a flow-through portion penetrating through the plates and through which a fluid is flowable. At least one set of the flow-through portions may be provided at one of the flow paths such that the fluid is flowable from one side of a flow-through portion to an other side of a flow-through portion. The flow-through portion may be disposed outside the fin plate. Each plurality of the plates may further include a through hole disposed outside the fin plate. Each plurality of the plates may further include a first boss portion formed in a substantially elliptical shape surrounding the flow-through portion and the through hole.

A heat exchanger includes: a first layer including first flow channels that are microchannels and arranged to extend side by side; and a second layer that is laminated on the first layer and that includes second flow channels that are microchannels and arranged to extend side by side. A first one end-side collective flow channel is in fluid communication with first ends of the first flow channels. A first other end-side collective flow channel is in fluid communication with second ends of the first flow channels. A second one end-side collective flow channel is in fluid communication with first ends of the second flow channels. A second other end-side collective flow channel is in fluid communication with second ends of the second flow channels.

A heat exchanger comprises a plurality of cells formed by a stack of alternate planar flow-guide plates (1) and heat transfer plates (2), each heat transfer plate having at least three apertures (3, 4, 6) therethrough, each aperture defining a part of a respective one of at least three fluid flow paths in the heat exchanger. Each flow-guide plate has apertures therethrough corresponding to at least two of the flow paths and a larger aperture (5, 7, 8) therethrough configured to guide fluid in the remaining flow path across the face of the heat transfer plates between which the flow-guide plate is located, each successive flow-guide plate in the stack forming part of a different flow path from the preceding one in the stack.

An inlet distributor for a plate heat exchanger is disclosed. The plate heat exchanger includes a plate set. A fluid channel is formed between each two adjacent plates of the plate set, and each plate has first fluid openings and second fluid openings to form inlet channels and outlet channel for fluid to alternatively flow into and out of the fluid channels. The inlet distributor includes a collecting pipe, and at least one horizontal partition plate disposed on the inner wall of the collecting pipe. The collecting pipe can be mounted on an inlet end of the inlet channel, and the horizontal partition plate is coaxially extended into the inlet channels. When the fluid flows into the collecting pipe, the horizontal partition plate separates liquid and vapor of the fluid and guides the vapor to fluid channel in different position away from the inlet end, along the horizontal partition plate.
