Definitions

  • the invention relates to a heat exchanger for indirect heat transfer between a first medium and a second medium according to the horr1.
  • Such a heat exchanger usually has a jacket (also called “shell”), which defines a jacket space for receiving a liquid phase of the first medium, and at least one heat exchanger block (also referred to as “core” or “block”), the first Heat transfer passages for receiving the first medium and second heat transfer passages for receiving the second medium, so that between the two media indirectly heat transferable, wherein the heat transfer block is arranged in the jacket space, that it is umvorbar with a located in the shell space liquid phase of the first medium ,
  • Such a heat exchanger is for example in " The standards of the brazed aluminum plate-fin heat exchanger manufacturer's association (ALPEMA) ", third edition, 2010, page 67 shown in Figure 9-1.
  • ALPEMA brazed aluminum plate-fin heat exchanger manufacturer's association
  • Such a design of a heat exchanger is also called “core-in-shell” or “block-in-shell” heat exchanger.
  • the driving force for the flow through the at least one heat exchanger block with the first medium is preferably generated by the thermosiphon effect due to the evaporation itself.
  • the jacket space of the heat exchanger not only fulfills the purpose of an original container, but also serves as a separating apparatus for separating the generated vapor of the first medium from the refrigerant liquid and the liquid phase of the first medium, respectively.
  • a free surface of the liquid phase of the first medium forms in the shell space.
  • the jacket of the heat exchanger which is preferably cylindrical in shape, can be oriented both horizontally and vertically as far as the orientation of the longitudinal or cylindrical axis is concerned.
  • the heat exchanger block is flowed through mainly by the refrigerant liquid mainly upwards.
  • the flow direction of the stream to be cooled (second medium) is not restricted in particular.
  • the heat exchanger on a mobile surface e.g. Therefore, the well-known problems associated with partially liquid-filled containers may arise, in particular, the liquid may reciprocate in the container space so that e.g. At several locations in the mantle space, time-varying levels result. As a result, e.g. the immersion depth of the heat exchanger blocks into the liquid phase of the first medium, which is e.g. may affect the effectiveness of heat transfer. If possible, therefore, the liquid movement of the bath is to be damped so far that a safe and reliable operation can be guaranteed.
  • the present invention seeks to provide a heat exchanger of the type mentioned, which reduces the above problem.
  • a plurality of parallel cylindrical channels for guiding the first medium is provided in the lateral space laterally to the at least one heat exchanger block, which in particular are in flow connection only with the bath or the liquid phase.
  • Cylindrical here means in the general sense that the base of the cylinder, which in the present case is the cross-sectional area of the channel can be any flat surface, which may be circular (circular cylinder), rectangular, square, triangular or hexagonal in particular.
  • the respective cylinder is formed by displacement of that flat surface along a straight line or longitudinal axis, which does not lie in the plane of the flat surface and preferably runs normal to that flat surface or cross-sectional surface.
  • the individual channels are furthermore preferred over their circumference by walls, and preferably in the form of circumferential walls, in particular completely closed walls, separated from each other. In such completely closed walls, the medium flowing in the respective channel along the longitudinal axis of the channel can not enter an adjacent channel (transverse to the longitudinal axis).
  • a channel, some channels or all channels have a separate, own circumferential wall.
  • a wall of a channel also forms part of a wall of an adjacent channel. This can also apply to several or all channels.
  • the liquid phase of the first medium in the jacket space of the heat exchanger can advantageously be calmed in fluctuating movements of the heat exchanger.
  • a fluctuating movement is understood in particular to mean a movement in which the longitudinal or cylindrical axis of the jacket alters its spatial position or inclination, in particular periodically (for example, due to the sea in an arrangement of the heat exchanger on a float on a body of water).
  • the channels - are the channels - based on a designated heat exchanger, which is assumed in the following - e.g. Aligned along the vertical, the liquid phase during operation of the heat exchanger at the upper end of the heat exchanger block exit and flow through the channels laterally back to the heat exchanger block.
  • the channels thereby represent a flow resistance in the horizontal direction, which suppresses a movement of the liquid phase of the first medium along the horizontal.
  • the liquid phase may flow back and forth in the channels during fluctuating movements of the heat exchanger, the channels also acting as flow resistors in the horizontal direction due to the limited flow cross section and therefore damping a corresponding movement of the liquid phase of the first medium , If the longitudinal axes of the parallel channels are aligned horizontally, in particular a liquid movement is damped, which results from a fluctuating movement in which the inclination of the longitudinal axes changes.
  • the at least one heat exchanger block can be any possible heat exchanger, which in particular can transfer heat indirectly from the second medium to the first medium.
  • the heat exchanger block is a plate heat exchanger.
  • Such plate heat exchangers generally have a plurality of mutually parallel plates or plates, which form a plurality of heat transfer passages for participating in the heat transfer media.
  • a preferred embodiment of a plate heat exchanger has a plurality of heat conducting structures, e.g. in the form of average meandering, in particular corrugated or folded sheets (so-called fins), which are each arranged between two parallel partition plates or sheets of Platten Vietnamese pyramidtragers, wherein the two outermost layers of the Platten Vietnamese Bulgariaschreibers are formed by cover plates.
  • a plurality of parallel channels or a heat transfer passage are formed between each two partition plates or between a partition plate and a cover plate due to the respective interposed fin, through which a medium can flow.
  • Heat transfer may therefore take place between the media flowing in adjacent heat transfer passages, the heat transfer passages associated with the first medium being referred to as first heat transfer passages and the heat transfer passages associated with the second medium correspondingly being referred to as second heat transfer passages.
  • first heat transfer passages are open along the vertical upwards and downwards and in particular not closed by end strips, so that the liquid phase of the first medium from below can get into the first heat transfer passages and top of the plate heat exchanger from the first heat transfer passages as liquid and / or gaseous Phase can escape.
  • cover plates, separator plates, fins and side bars are preferably made of aluminum and are used e.g. soldered together in an oven. Via corresponding headers with nozzles media such as e.g. the second medium are introduced into or removed from the associated heat transfer passages.
  • the jacket of the heat exchanger can in particular have a circumferential, (circular) cylindrical wall, which is preferably aligned with a heat exchanger arranged as intended, so that the longitudinal axis or cylinder axis of the wall or the jacket extends along the horizontal or along the vertical.
  • the jacket preferably has mutually opposite walls connected to that wall, which extend transversely to the longitudinal axis or cylinder axis.
  • the at least one plate heat exchanger is designed to cool the second medium guided in the second heat transfer passages against the first medium guided in the adjacent first heat transfer passages and / or at least partially to liquefy, so that forms a gaseous phase of the first medium, wherein the jacket space is formed for collecting the gaseous phase.
  • the at least one plate heat exchanger is formed so that the first medium rises during operation of the heat exchanger in the at least one plate heat exchanger, namely in designated first heat transfer passages of the at least one plate heat exchanger, in particular the at least one plate heat exchanger is designed to the second medium in the second heat transfer passages in countercurrent or cross-flow to the first medium to lead.
  • the liquid phase of the first medium emerging at the upper end of the plate heat exchanger together with the gaseous phase flows down again on the sides of the plate heat exchanger, possibly in the vertically oriented channels.
  • the channels or their walls are fixed to each other so that they form a coherent unit, which is also referred to as a register.
  • These Unit is preferably formed separately from the heat exchanger block and / or jacket.
  • the channels or at least some of the channels along their respective longitudinal axis are formed longitudinally, ie, the extent along the respective longitudinal axis is greater than the largest inner diameter of the respective channel perpendicular to the respective longitudinal axis.
  • the channels are thus flowed through along their respective longitudinal or cylindrical axis of the liquid phase of the first medium, wherein they each have an opening at the two end faces, via which the liquid phase in the respective channel can enter or exit.
  • the two openings of a channel lie opposite each other along the longitudinal or cylindrical axis of the respective channel, that is, they are aligned with one another.
  • all channels - with respect to the longitudinal axes - have the same length.
  • some or all channels for adapting the unit to a curved portion of an inner side of the shell of the heat exchanger - with respect to the longitudinal axes - have different lengths. This makes it possible to achieve a gradation of an outer side of the assembled unit following the course of the inner side region (e.g., a hollow cylindrical shell).
  • the unit arranged in the jacket space on the jacket so that it does not contact the at least one heat exchanger block in particular.
  • the unit may also be fixed to the at least one heat exchanger block or to a separate carrier.
  • the respective channel is formed by a hollow profile.
  • the hollow profile which is preferably made of a metal (such as aluminum or steel), thereby forms a wall surrounding the respective channel and limits or thereby forms the respective channel.
  • the hollow profiles are connected to each other so that that coherent unit is formed.
  • the hollow sections can be welded together or be suitably fixed to each other by other fastening means, so that that unit or the hollow profile register is formed.
  • the channels are formed by a plurality of interconnected plate-shaped elements (e.g., sheets). These elements may be flat (e.g., planar sheets) or may have a structure (e.g., those elements may be formed as cross-section corrugated or folded or serrated elements / sheets).
  • the individual elements may e.g. be fixed by nesting each other and may optionally be additionally fixed to each other.
