Definitions

  • the invention relates to a wound heat exchanger.
  • Such a heat exchanger is used for indirect heat transfer between at least a first and a second medium and has a shell space for receiving the first medium, as well as a tube bundle arranged in the shell space with a plurality of tubes for receiving the second medium, those tubes being helical in several tube layers are wound on a core tube of the heat exchanger.
  • DE-A-1939564 discloses such a heat exchanger and furthermore a heat exchanger according to the preamble of claim 1.
  • Spacers are preferably provided between the pipe layers, via which the respective pipe layer is supported on the pipe layers below.
  • the first medium guided in the shell space over the tube bundle it is of particular importance that the first medium is distributed as evenly as possible over the tube bundle in order to be able to ensure efficient heat transfer.
  • the fluid first medium guided on the jacket side is passed outward to the outer pipe layers (in the radial direction of the pipe bundle) due to various effects in the jacket space.
  • One of the reasons for this is the centrifugal force which, due to the helical winding of the individual tubes of the tube bundle of the heat exchanger, acts on the parts of the first medium flowing along the surfaces of the tubes.
  • these parts of the first medium are forced outward in the radial direction of the tube bundle towards the outer tube layers.
  • an uneven distribution of the first medium is generated in favor of the outer tube layers.
  • the present invention is therefore based on the object of creating a heat exchanger of the type mentioned at the beginning which counteracts the aforementioned problems.
  • a heat exchanger for indirect heat transfer between a first and a second medium is provided with a shell space for receiving the first medium, a tube bundle arranged in the shell space with a plurality of tubes for receiving the second medium, the respective tube being helically wound onto a core tube , so that the tube bundle has several tube layers arranged on top of one another, and at least one spacer via which a first tube layer of the tube bundle located further out in the radial direction of the tube bundle is supported on an adjacent second tube layer further inside in the radial direction of the tube bundle.
  • the at least one spacer has a flow-guiding means. This has the effect that a part of the first medium flowing in the jacket space along the first (outer) and / or the second (inner) pipe layer is deflected in the direction of the pipe layer located radially further inward.
  • the flow-guiding means has an end face of the spacer which connects a front side of the spacer facing away from the core tube with a rear side of the spacer facing the core tube, the end face having an inclination towards the second pipe layer, so that a front side of the spacer facing away from the core tube first pipe layer against the end face of the flowing part of the first medium is deflected by the end face in the direction of the second pipe layer.
  • the flow-guiding means has at least one guiding element which is fixed on a base of the spacer that extends along the longitudinal axis and over which the first pipe layer extends on the second Supports pipe layer, wherein the at least one guide element forms an impact surface which has an inclination towards the second pipe layer.
  • the pipe layer further out does not necessarily have to be the outermost pipe layer.
  • a large number of pipe layers can of course be provided in the heat exchanger according to the invention (see also below), in which case one or more spacers with said flow-guiding means can be provided between each two (in the radial direction) adjacent pipe layers, with the flow of the respective Part of the first medium is always directed from the (first) pipe layer located radially further outside to the adjacent (second) pipe layer located radially further inside.
  • the spacer elements with said flow-guiding means are provided in such a way that the first medium is distributed as evenly as possible over the tube bundle (based on the entire length of the tube bundle along the longitudinal axis of the shell / core tube of the heat exchanger).
  • spacers are not provided between all pipe layers, but only between certain pipe layers (depending on the expected uneven distribution of the first medium).
  • Conventional spacers for example, or spacers which do not show the flow-deflecting effect according to the invention or show the flow-deflecting effect to a much lesser extent, can then be provided between the remaining pipe layers.
  • the invention advantageously counteracts the uneven distribution in favor of the outer pipe layers, so that as a result the jacket-side coolant or the first medium is better distributed and the performance of the wound heat exchanger is improved accordingly.
  • the flow-guiding means has an end face of the at least one spacer.
  • This end face is preferably an integral component of the at least one spacer or a side of the spacer formed in one piece with the spacer.
  • the front side connects a front side of the spacer facing away from the core tube with a rear side of the spacer facing the core tube.
  • the front side extends thus essentially along the radial direction of the tube bundle and in particular has an inclination with respect to the radial direction.
  • said end face can also extend in sections between two adjacent pipe sections of the first pipe layer, these sections of the end face each being part of a projection of the spacer element, these projections each being between two adjacent pipe sections or pipe coils of the first pipe layer and each from an edge portion of a base of the at least one spacer protrude in the radial direction of the tube bundle).
  • the vertical spacing of the pipe windings in the respective pipe layer is thus fixed by these projections.
  • the said end face of the at least one spacer for influencing or deflecting the flow of the first medium has an inclination towards the second pipe layer or an inclination with respect to a tangential direction of the pipe sections of the second pipe layer resting on the spacer so that the part of the first medium flowing along the pipe of the first pipe layer against the end face of the at least one spacer is deflected by the end face in the direction of the second pipe layer.
  • the core tube extends along a longitudinal axis which is preferably oriented parallel to the vertical, in relation to a heat exchanger arranged as intended.
  • the heat exchanger preferably also has a jacket surrounding the jacket space, which extends coaxially to the core tube along the said longitudinal axis.
  • the at least one spacer or the said flow-influencing end face of the spacer extends along the longitudinal axis.
  • the flow-guiding means has at least one guide element, for example in the form of at least one guide plate, which is fixed to a base of the spacer extending along the longitudinal axis, via which the first pipe layer is supported on the second pipe layer.
  • the basis takes over the production of the distance between the individual pipe layers or the transfer of the load of the respective outer pipe layer to the pipe layer underneath, while the at least one guide element preferably only takes on a flow-guiding function.
  • the at least one guide element forms an impact surface on which the said deflecting part of the first medium impinges, with that impact surface again having an inclination towards the second pipe layer (or an inclination in relation to a tangential direction of the the spacer adjacent pipe sections of the second pipe layer).
  • the guide element extends in sections between adjacent pipe sections of the second pipe layer or the pipe layer located radially further inward.
  • the at least one spacer can also have a plurality of guide elements which are fixed to the base along the longitudinal axis, so that there is a gap between every two guide elements adjacent in the direction of the longitudinal axis.
  • the individual guide elements then extend in sections between each two associated pipe sections of the second pipe layer or protrude into a space between the two pipe sections.
  • the at least one guide element (or the plurality of guide elements) is arranged on an upstream or downstream section of the base of the at least one spacer in relation to the flow direction of the first medium, in particular on an end face of the base which connects a front of the base to a rear of the base, the rear facing the core tube.
  • said means is formed by a plurality of grooves formed in the spacer or has such grooves.
  • the channels each extend inwards along the radial direction, sloping inwards so that a part of the first medium flowing along the first pipe layer, in particular from top to bottom, can get into the channels and inwards to the second pipe layer is distracted.
  • the grooves are formed, for example, on an end face of the respective spacer against which that along the first pipe layer or the first medium flowing along the pipe of the first pipe layer flows or on which the first medium flows down from top to bottom.
  • a spacer can thus have one, two or three of the aforementioned components for directing the flow.
  • the heat exchanger has a plurality of spacer elements between the first and the second pipe layer, the spacer elements each having a flow-guiding means which is designed according to one of the embodiments described or claimed herein.
  • the heat exchanger has spacer elements between several or between all adjacent pipe layers, the respective spacer element preferably having a flow-guiding means which is designed according to one of the embodiments described or claimed herein.
  • the number of spacers arranged between the adjacent pipe layers is constant, with a plurality of spacers each being arranged one above the other to support the pipe layers in a radial direction of the pipe bundle.
