Definitions

  • the invention relates to a recuperative spiral heat exchanger with spiral-shaped partition walls bent from sheet metal strips standing upright next to each other between the fluid material flows which have a usable temperature gradient, of which two mutually adjacent partition walls each include a flow channel for one of the two material flows between them and the one located between two flow channels Spiral space forms the flow path for the other material flow. and with inlet and outlet openings for both material flows.
  • Such a spiral heat exchanger is known from GB-A-778 541.
  • the known spiral heat exchanger is limited by design to two courses of a spiral for each material flow.
  • a material flow is distributed over the two aisles.
  • One of the material flows flows from the periphery of the spiral to the center, while the other material flow flows from the center to the periphery.
  • Two spiral flow channels each carry an assigned material flow.
  • the two spiral flow channels for each material flow in the known heat exchanger must be relatively long. Long flow channels, however, have the disadvantage that high pressure losses occur.
  • the invention has for its object to design a spiral heat exchanger of the type mentioned so that any number of flow channels are possible.
  • This object has been achieved according to the invention in that it has two multi-start spirals arranged one behind the other in a closed housing with opposite directions of rotation and in that the inlet and outlet openings for the two material flows are arranged in the center of the spirals.
  • each material flow can be divided between the spiral arms, with the advantage that either the spiral flow channels between the inlet and outlet of the respective material flow are relatively short, or a correspondingly higher throughput is possible, both advantages without reducing the actual heat exchanger area can be achieved, the dimensions of which must be adapted to the achievable order of magnitude of the performance of a heat exchanger.
  • a spiral heat exchanger designed in accordance with the invention can thus achieve the full performance for which it is designed, owing to the given heat exchanger surface, without the disadvantages of conventional spiral heat exchangers of conventional design that have been accepted up to now.
  • a heat exchanger designed with a multi-course spiral also has the advantage that it can be manufactured easily since the individual flow channels are relatively short and consequently the bending of the partition walls into the spiral shape is also easy because the individual turns are only slightly intertwined.
  • each flow channel within one of the spirals can be short, since the total length of each flow channel can be predetermined by its course within both spirals.
  • the connection of two opposing spirals gives each flow channel an approximately S-shaped course, with the S-bends each lying within one of the spirals.
  • This type of spiral formation of the heat exchanger surfaces facilitates their manufacture and enables relatively inexpensive manufacture from sheet metal strips standing upright next to one another, two sheet metal strips each enclosing a flow channel between them, which is covered at the top and bottom by a cover, for. B.
  • the inflow and outflow openings are each arranged in a housing area corresponding to the center of the spirals.
  • Corresponding line connections e.g. B. connecting piece, can be provided.
  • the drawing shows a schematic sectional view of a spiral heat exchanger with a lower housing wall 1 and box-shaped side walls 2.
  • the heat exchanger surfaces are arranged spirally in the manner shown.
  • a material flow can be supplied via inflow openings 3-3 "'. Since there are four inflow openings and a flow channel 4-4'" is connected to each of the inflow openings 3-3 '", the supplied material flow is distributed over the four flow channels, which are delimited by two adjacent partition walls 5, 6, here referred to here using the example of the flow channel 4.
  • the flow channels 4-4 '" are arranged in a spiral manner and thus form a multi-course, clockwise spiral. There are free spiral spaces between the individual flow channels 4-4 "', which also serve as flow channels for a second stream of material which is passed through the opening 9.
  • This second stream of material is fed through a single inflow opening of larger diameter, which is arranged in the left, counterclockwise spiral and is designated by 7.
  • This second spiral has the outflow openings 8-8 '", via which the first material flow, which enters via the inflow openings 3-3"' of the right spiral, is discharged again.
  • the outflow opening 8 is thus located at the end of the flow channel 4, that goes from the inflow opening 3.
  • the remaining inflow and outflow openings 3'-3 "'and 8'-8"' assigned to each other each have the same index.
  • the second stream of material flowing in via the larger inflow opening 7 in the left spiral enters the spiral spaces between the flow channels in regions indicated schematically by arrows and flows through the spiral spaces to the right spiral and thus in counterflow to the stream of material supplied to the right spiral, where it flows through the outflow opening 9 located there emerges again from the housing of the heat exchanger.
