Each leak-tight conduit module is sealed only near the ends of the module that are disposed in the respective manifold cavity.

A heat exchange structure includes a primary heat exchange body with a first fluid channel fluidly separated from a second fluid channel by a barrier channel, an inlet manifold in fluid communication with the first fluid channel, and a secondary heat exchange body. The secondary heat exchange body is in fluid communication with the barrier channel, is arranged within the inlet manifold, and fluidly couples the barrier channel to the external environment. Fluid systems and heat exchange methods are also described.

A plate for a heat exchanger between a first medium and a second medium, with a main plane of extension and a main longitudinal direction includes a first heat transfer surface, parallel to said main plane and in contact with the first medium; and a second heat transfer surface, parallel to said main plane and in contact with the second medium. The first surface includes a first medium inlet region, a first medium transfer region and a first medium outlet region including a first medium outlet port. The second surface includes a second medium inlet region, a second medium transfer region and a second medium outlet region, which second medium inlet region overlaps with the first medium outlet region and includes a second medium inlet port not overlapping, with the first medium outlet port. The first medium outlet region includes a protruding ridge extending from a respective edge of the first surface and perpendicularly to the longitudinal direction, and the protruding ridges form a barrier system for the first medium and define a channel along which the first medium is forced to travel, which channel runs first towards, then around and thereafter away from the second medium inlet port.

A method of forming a component for a heat exchanger is disclosed. The method comprises machining a portion of a metal sheet to form a plurality of protrusions, and forming apertures in the portion of the metal sheet so as to form a plurality of ribs defined by adjacent ones of the apertures, wherein at least one protrusion is located on each of said ribs.

In some examples, a plate fin heat exchanger including a cold passage defined by a cold frame; a hot passage defined by a hot frame; a tube sheet between the cold passage and the hot passage; a top side plate; and a bottom side plate, wherein the cold frame includes a first bar and a second bar attached at a corner of the heat exchanger, wherein at least a portion of the first bar is configured to be removed from the cold frame, wherein the hot frame includes a third bar and a fourth bar attached at the corner of the heat exchanger, wherein at least a portion of the third bar is configured to be removed from the hot frame, and wherein the corner of the heat exchanger defined by at least one of the hot frame or the cold frame has a non-square shape.

A plate heat exchanger includes heat transfer plates each of which has openings at four corners thereof, and which are stacked together. The heat transfer plates are partially brazed together such that a first flow passage through which first fluid flows and a second flow passage through which second fluid flows are alternately arranged, with an associated heat transfer plate interposed between the first and second flow passages. The openings at each of the four corners communicate with each other, thereby forming a first header and a second header, the first header allowing the first fluid to flow into and flow out of the first flow passage, the second header allowing the second fluid to flow into and flow out of the second flow passage.

An apparatus is provided. The apparatus includes a heat exchanger providing heat transfer between a first medium and a second medium. The apparatus also includes a movable aperture integrated onto a face of the heat exchanger and regulating a flow of the first medium based on a position of the movable aperture. The apparatus further includes an actuator controlling the position of the movable aperture.

This disclosure describes an improved heat transfer system for use in reaction vessels used in chemical and biological processes. In one embodiment, a heat transfer baffle comprising two sub-assemblies adjoined to one another is provided.

A heat exchanger that includes first and second headers, a first flow conduit fluidly connecting the first and second headers to allow for a flow of a first fluid through the heat exchanger, the first flow conduit being bounded by a first generally planar wall section extending between the first and second headers, a second flow conduit to allow for a flow of the second fluid through the heat exchanger, the second flow conduit being bounded by a second generally planar wall section spaced apart from the first generally planar wall section to define a gap therebetween, and a thermally conductive structure arranged within the gap and joined to the first and second generally planar wall sections to transfer heat therebetween. The thermally conductive structure is isolated from the first fluid by the first generally planar wall section and from the second fluid by the second generally planar wall section.

A brazed plate heat exchanger (100; 200) comprises a number of heat exchanger plates (120a-120h; 201-204) provided with a pressed pattern of ridges (R) and grooves (G) adapted to keep the plates on a distance from one another by providing contact points between crossing ridges (R) and grooves (G) of neighbouring plates under formation of interplate flow channels for media to exchange heat, said interplate flow channels being in selective fluid communication with first, second, third and fourth large port openings (O1, O2, O3, O4; 210a, 210b, 210c, 210d) and first and second small port openings (SO1, SO2) for letting in fluids to exchange heat, characterized in that fluid passing between the first and second large port openings (O1, O2; 210a, 210b) exchanges heat with fluids passing between third and fourth port openings (O3, O4; 210c, 210d) over a first heat exchanging portion of each plate and fluid passing between the first and second small port openings (SO1, SO2) over a second portion of each plate.
