Definitions

  • the invention relates to a heat exchanger for two fluids that exchange heat in cross flow with the features of the preamble of claim 1.
  • heat exchangers which have a multiplicity of layers of structured sheets which are layered crosswise.
  • the structured sheets form channels in which the heat-exchanging fluids can flow.
  • the structured sheets can in particular have a corrugated structure and are separated from one another by smooth sheet layers.
  • the object of the present invention is to further develop the known heat exchanger in such a way that it is ensured becomes that the inlet cross section of the channels always remains free and uniformly shaped outer sides of the heat exchanger are formed.
  • the heat exchanger according to the invention is characterized in that strips are provided, each of which surrounds an edge region of the structured sheets running in the flow direction of one or the other fluid on both sides. Each strip thus forms a seam along the edge, which prevents the end region from reaching the inlet cross section of the adjacent channels. This ensures that there are no additional pressure losses within the heat exchanger.
  • Another advantage of this design can be seen in that the sealing of the heat exchanger is simplified, since the additional strips thicken the end regions somewhat and exert a certain additional pressure on the end regions when the cuboidal laminated core is later incorporated into a frame or a housing.
  • An embodiment of the heat exchanger is preferred, in which the strips are formed on smooth sheets arranged between the structured sheets.
  • the strips are preferably integral components of the smooth sheet.
  • This design also has the advantage that the tightness of the heat exchanger is increased. By hemming the two edges, a risk of injury during manufacture and handling is also minimized.
  • the strips the width of which is between 0.01 and 0.02 m, preferably 0.015 m. This width gives the structured and the smooth sheet metal layer a certain stiffness in one direction, transverse to the longitudinal extent of the strip.
  • the heat exchanger can also be brought into contact with aggressive fluids.
  • it is proposed to form the structured sheets and / or the strips or smooth sheets from a corrosion-resistant, preferably high-temperature corrosion-resistant, material.
  • the strips can be connected to a structured sheet of metal using a force fit.
  • the strip can have a structure that is negative with respect to the structured sheet metal, so that the structure of the strips snap into the structure of the sheet metal.
  • An embodiment is preferred in which the strips are connected to the structured sheet metal by soldering, preferably brazing. This ensures that the strips are easy to handle do not detach from the structured sheets and the heat exchanger is tight.
  • the frame preferably has a U-shaped part which can be connected to a detachable crossbar on its free legs.
  • the U-shaped part in the traverse can be connected by a screw connection.
  • the screw connection it is proposed to form a threaded section at each end of each leg and to provide the crossbar with openings so that the crossbar is pressed against the stack of sheets by means of a nut which can be screwed onto the threaded section.
  • the entire laminated core can also be soldered on the end faces or on all contact points of the laminates to ensure good tightness and durability.
  • Solder can be introduced as foils before layering the sheets and / or on the face side as powder after layering the sheets.
  • FIG. 1 schematically, a perspective view of a heat exchanger
  • Figure 2 shows a structured and a smooth sheet metal layer in the front view and Figure 3 shows a heat exchanger with a frame.
  • the heat exchanger 1 shows a heat exchanger 1, which is a cross-flow heat exchanger.
  • the fluids introduced into the heat exchanger flow crosswise along the flow directions A, B.
  • the heat exchanger is constructed from a large number of structured sheets 2, 20 which are layered crosswise one above the other with the interposition of smooth sheets 8, 80.
  • the structured sheets 2, 20 have a corrugation which forms the channels 3, 30.
  • the channels 3, 30 are separated from one another and run essentially perpendicular to one another.
  • Each sheet 2, 20 has an edge region 6, 7 in the flow direction A or B, which is surrounded by a strip 4 or 5.
  • Each strip 4, 5 extends over the entire length of the edge region 6, 7.
  • the strips 4, 5 are formed as integral components of the smooth sheet 8, 80.

The threaded sections 14 extend through openings in a crossmember 13 which bears against the packing of the sheets. Nuts 16 are provided for bracing the sheets together, which are screwed onto the threaded sections 14. It is not shown how the fluids get into the heat exchanger from the end faces.

Abstract

L'invention concerne un échangeur de chaleur (1) pour deux fluides à courants croisés, comportant des strates à couches croisées de tôles structurées (2, 20), notamment ondulées, qui forment une pluralité de canaux (3, 30) de circulation et entre lesquelles sont disposées des tôles lisses (8, 80). La zone marginale (6, 7) de la tôle structurée (2, 20) qui s'étend dans le sens d'écoulement de l'un ou de l'autre fluide est entourée des deux côtés par des bandes (4, 5) qui font partie intégrante de la tôle lisse (8, 80).
