Definitions

  • the present disclosure relates to a plate heat exchanger comprising a top head, a bottom head, four side panels, and four corner girders, wherein the side panels and the corner girders extend along a longitudinal direction from the bottom head to the top head.
  • Each side panel is associated with two corner girders, wherein the top head, the bottom head, the four side panels and the four corner girders are bolted together to form a sealed enclosure for housing a pack of heat exchanging plates.
  • One certain type of plate heat exchanger is assembled by bolting a top head, a bottom head and four side panels to a set of corner girders to form a box-like enclosure around a stack of heat transfer or heat exchanging plates.
  • This certain type of plate heat exchanger is referred to as a block-type heat exchanger.
  • One example of a commercially available block-type heat exchanger is the heat exchanger offered by Alfa Laval AB under the product name Compabloc. Such a block-type heat exchanger is disclosed in EP2672215 .
  • Other block-type plate heat exchangers are disclosed in patent documents EP 165179 and EP 639258 .
  • Block-type heat exchangers are commonly used in applications where the heat exchange fluids or one of the heat exchange fluids are provided at a high pressure, such as up to 40 bars. Moreover, the block-type heat exchangers are commonly used where relatively speaking large heat exchangers are desired. As an example, a side panel of a typical block-type heat exchanger may be several meters tall and several meters wide. The high pressure in combination with the size demands a high strength box-like enclosure to withstand the forces originating from the pressure of the heat transfer fluids. Also for smaller size block-type heat exchangers a high strength box-like enclosure is commonly needed.
  • the box-like enclosure i.e. the parts forming the enclosure, of a block-type heat exchanger is commonly made of metal, such as steel.
  • metal such as steel.
  • the use of a metal case providing a sufficient mechanical strength brings about that the box-like enclosure commonly requires a significant amount of material in order to be fabricated, thus becoming heavy and costly in order to provide a required mechanical strength.
  • a plate heat exchanger comprising a sealed enclosure for housing a pack of heat exchanging plates which is easier and less costly to fabricate and handle while exhibiting a desired mechanical strength.
  • the plate heat exchanger comprising a top head, a bottom head, four side panels, and four corner girders, wherein the side panels and the corner girders extend along a longitudinal direction from the bottom head to the top head, wherein each side panel is associated with two corner girders, wherein the top head, the bottom head, the four side panels and the four corner girders are bolted together to form a sealed enclosure for housing a pack of heat exchanging plates, wherein at least one of the side panels is divided into at least two separate plates arranged one after another along the longitudinal direction, wherein the at least two separate plates include a first separate plate being adapted to be bolted to the top head and a second separate plate being adapted to be bolted to the bottom head.
  • the first separate plate is provided with bolt holes along first, second and third edges and may be adapted to be bolted to the top head along a first edge and may adapted to be bolted to two associated corner girders along second and third edges of the first separate plate, wherein a fourth edge of the first separate plate may be free from bolt holes
  • the second separate plate may be provided with bolt holes along first, second and third edges and may be adapted to be bolted to the bottom head along a first edge and may be adapted to be bolted to the two associated corner girders along second and third edges of the second separate plate, wherein a fourth edge of the second separate plate may be free from bolt holes.
  • the plate heat exchanger is advantageous in that at least one of the side panels forming part of the sealed enclosure for housing the pack of heat exchanging plates is divided into at least two separate plates arranged one after another along the longitudinal direction.
  • the handling of the at least two separate plates may become significantly simplified as compared to handling a side panel formed of a single part.
  • the handling of separate plates may significantly lower the requirements on the equipment required during for instance transportation, installation and maintenance as each of the separate plates are smaller and lighter as compared to a side panel being formed in a single piece.
  • the mechanical properties of the respective separate plates may be tailored to suit specific needs of a particular installation.
  • one separate plate may be made thicker and thus stronger as compared to another separate plate or plates. It is thus possible to reduce material consumption, since the thickness of the respective separate plates may be chosen based on the forces a particular separate plate is subjected to.
  • separate plates not exhibiting weakening structures or details such as openings may be made thinner as compared to separate plates not exhibiting weakening structures or details, which allows for a reduced material consumption.
  • a modular system for forming the sealed enclosure for housing the pack of heat exchanging plates may be provided.
  • the respective side panels of the sealed enclosure may be formed of a plurality of standard modules in form of separate plates having a standard height or standard heights.
  • the modular system may include separate plates for instance including an opening or similar and flat separate plates without any opening or similar. If specific heights of the side panels, other than those that may be formed or achieved by available standard sized separate plates are needed, a single plate of a specific height may easily be formed to complement the standard sized separate plates so as to achieve any height of the side panels.
  • the modular system may thus facilitate the fabrication of the sealed enclosure and reduce the fabrication cost.
  • first, second and third edges of the first separate plate and the second separate plate the respective plates may be bolted to the corner girders and top respective bottom head without requiring any additional details for forming the sealed enclosure for housing the pack of heat exchanging plates.
  • no additional girders, reinforcing elements or similar may be required.
  • the mounting of the first separate plate and the second separate plate may be facilitated as a limited number of bolts may be used.
  • the plate heat exchanger may further comprise a lining covering an internal surface area of the divided side panel thereby providing a closed internal surface area of the side panel being divided into two or more separate plates arranged one after another along the longitudinal direction.
  • a lining covering an internal surface area of the divided side panel By providing a lining covering an internal surface area of the divided side panel, a closed internal surface area of the side panel being divided into two or more separate plates arranged one after another along the longitudinal direction may be achieved.
  • the lining may thus seal the surface of the divided side panel thereby making the divided side panel liquid or fluid tight, such that leakage of heat exchange fluids or heat transfer mediums may be counteracted.
  • the lining may be provided in form of a material capable of withstand e.g.
  • internal surface may refer to any surface area of the side panel facing the interior of the plate heat exchanger and not necessarily the complete surface area of the side panel concerned.
  • the first separate plate may be provided with an opening extending through the plate for providing a channel for a flow of heat transfer medium through the first plate
  • the second separate plate may be provided with an opening extending through the plate for providing a channel for a flow of heat transfer medium through the second plate.
  • At least one of the side panels may be divided into at least three separate plate modules arranged one after another along the longitudinal direction, which is advantageous in that a limited number of separate plate types may be used to form a large number of different types or heights of side panels. Further, the mechanical properties of the respective separate plate modules may vary so as to account for different requirements, such as different mechanical strengths or openings to give a few examples.
  • a third separate plate module arranged between the first and the second plate modules in the longitudinal direction, may be adapted to be bolted to two associated corner girders without being bolted to the top head or bottom head, which is advantageous in that no additional details for forming the sealed enclosure for housing the pack of heat exchanging plates may be required.
  • the third separate plate module may only be bolted to the two associated corner girders.
  • the mounting of the of the mounting of the third separate plate module may be facilitated as a limited number of bolts may be used.
  • a separate plate being provided with a channel for a flow of heat transfer medium through the plate may have a first thickness and wherein at the first side a separate plate not being provided with a channel for a flow of heat transfer medium through the plate may have a second thickness, wherein the first thickness may be greater than the second thickness, which is advantageous in that the reduced strength owing from the channel of flow may be compensated for in an efficient manner.
  • the separate plate being provided with a channel for a flow of heat transfer medium through the plate may be made thicker so as to account for the channel for a flow without having to change or alter the separate plate not being provided with a channel for a flow. This arrangement may result in a reduced material consumption and hence a reduced cost while still maintaining a desired mechanical strength of the side panel.
  • the first thickness may be at least 110%, preferably at least 120% of the second thickness.
  • At least the side panel or side panels being provided with an opening extending through the respective side panel for providing a channel for a flow of heat transfer medium through the side panel may be divided into two or more separate plates arranged one after another along the longitudinal direction, which is advantageous in that material consumption of the side panel may be reduced while maintaining a desired mechanical strength of the side panel.
  • Each of the two corner girders associated with the divided side panel may be provided with a longitudinally extending notch, wherein the notch, as seen in a cross-section across the longitudinal direction, may positioned at a corner formed by a surface facing the side panel and a surface facing the other corner girder, wherein the notch extends along the longitudinal direction from an interface between the top head and the corner girder to an interface between the bottom head and the corner girder, wherein the longitudinally extending notch together with the separate plates of the side panel form a groove extending along the longitudinal direction, the groove being configured to receive and clamp an edge portion of the lining, which is advantageous in that the lining may be clamped between the corner girders and the side panel while mounting the side panel to the corner girders.
  • the notch may act as a mechanical stop and abut the side panel when mounting the side panel to the corner girders.
  • the height of the notch may thus for instance be slightly lower than an initial thickness of the lining, so as to compress the lining slightly during mounting.
  • the height of the notch may be different and may for instance account for the thickness of a gasket which may be provided between the lining and the corner girders.
  • the top head may, on an edge surface facing the divided side panel, be provided with a notch extending in a transverse direction along the edge surface, wherein the notch, as seen in a cross-section across the transverse direction, is positioned at a corner formed by the edge surface and an internally facing major surface of the top head, wherein the notch extends from an interface between the first separate plate and a first of the two associated corner girders and an interface between the first separate plate and a second one of the two associated corner girders, wherein the notch extending in a transverse direction together with the first separate plate forms a groove extending along the transverse direction, the groove being configured to receive and clamp an edge portion of the lining, which is advantageous in that the lining may be clamped between the top head and the side panel while mounting the side panel to the top head.

  • the lining may have a thickness between 2 and 15 mm, preferably between 5 and 15 mm, more preferred between 8 and 12 mm, and preferably comprise stainless steel or titanium.
  • the lining may efficiently withstand the pressure of the fluids in the plate heat exchanger.
  • the lining may withstand irregularities, slots or gaps that may be present for instance at the interface between two separate plates. In other words, the fit between two adjacent separate plates need not be perfect as relatively speaking small gaps may be acceptable.
  • a relatively speaking thick lining may also mitigate the need for fixing adjacent separate plates to each other e.g. by using fasteners such as bolts or keyed surfaces interacting with each other.
  • Each of the two corner girders associated with the divided side panel may be provided with a first, transversely protruding, shoulder portion adapted to interact with the first separate plate and a second, transversely protruding, shoulder portion adapted to interact with the second separate plate
  • the first shoulder portion comprises a first abutment surface having an extension in a direction transverse to the longitudinal direction and facing the second shoulder portion

  • the first separate plate may comprise two abutment surfaces, each having an extension in a direction transverse to the longitudinal direction and facing away from the second separate plate, the two abutment surfaces being configured to interact with the respective first abutment surface of the two associated corner girders
  • the second separate plate may comprise two abutment surfaces, each having an extension in a direction transverse to the longitudinal direction and facing away from the first separate plate, the two abutment surfaces being configured to interact
  • the side panels of the plate heat exchanger may be formed as separate plates, since the side panels need not transfer forces acting to separate the top head from the bottom head.
  • the side panels may be made as a plurality of separate plates, where the separate palates need not interact with each other, while providing a mechanically strong sealed enclosure for housing a pack of heat exchanging plates.
  • the first abutment surface of the first shoulder portion, the second abutment surface of the second shoulder portion, the two abutment surfaces of the first separate plate and the two abutment surfaces of the second separate plate may be planar in cross section and have respective normal directions being parallel to the longitudinal direction, which is advantageous in that an efficient interaction between the abutment surfaces may be provided using a simple shape of the abutment surfaces.
