Definitions

  • the invention relates to a heat exchanger according to the features of the preamble of claim 1.
  • a heat exchanger has become known in which the hollow elements each have a positive or a negative dovetail-shaped profile on opposite narrow fissures, with a larger one when the profile of the preceding individual element engages with a subsequent individual element Form the single plate of the heat exchanger. Furthermore, plate-shaped holders are arranged at a distance from one another, which have grooves on the mutually opposite inner surfaces, into which the hollow elements with their profiles are inserted. The result is an arrangement of hollow elements spaced apart from one another. A first heat exchange medium flows through the spaces between the hollow elements. A second heat exchange medium flows through the cavities in the same. To supply this heat exchange medium, auxiliary profiles are required which cause the same to be deflected accordingly. The inlet and outlet openings are in the brackets.
  • the invention has for its object to improve the supply of heat exchange media flows while avoiding deflections of the same and thus the heat exchange, so that the dimensions of the heat exchanger can be reduced with the same performance.
  • the heat exchanger consists of plate-shaped hollow elements 1 which have a positive curved profile 2 or a negative curved profile 3 on opposite narrow sides.
  • the in large series e.g. As a continuous aluminum profile, from which the desired length is cut off, plate-shaped hollow elements 1 produced are successively inserted into one of the end walls 8 and 9 of a holder, preferably made of plastic material, in guide grooves 14 and 16, respectively. The other end wall 8 or 9 is then pressed onto the arrangement with its guide grooves 14 or 16. A positive profile 2 of an element then engages in the negative profile 3 of the preceding hollow element 1.
  • Slits 10 are arranged between the guide grooves 14 and 16, which enable a resilient yielding of the end wall sections between the guide grooves 14 and 16 when the hollow elements 1 are inserted and thus facilitate insertion.
  • the heat exchange medium to be treated is introduced in the direction of arrows 18 into the spaces between the plate-shaped hollow elements 1 and removed again in the direction of arrows 19. Since, as can be seen from FIG. 1, left-hand side, the heat exchange medium meets the positive profiling 2 of the first hollow element, the flow velocity is correspondingly increased. Cooling air is blown through the plate-shaped hollow elements 1 through slot-shaped inlet or outlet openings 21 in the direction of arrow 22.
  • each of the plate-shaped hollow elements 1 is pressed over by webs 7, by means of which on the one hand the stability of the hollow elements is significantly improved. On the other hand, heat is extracted from the webs 7 by the cooling air flowing past.
  • a heat exchanger is thus built up without adhesive work or other complex work processes.
  • the plate-shaped hollow elements 1 only need to be inserted, the grooves 16, 18 being somewhat narrower than this corresponds to the height of the plate-shaped hollow elements 1, so that an elastic bend promoted by the slots 10 and a corresponding clamping of the plate-shaped hollow elements is achieved.
  • the heat transfer is significantly improved compared to heat exchangers of the same size.
  • the air flow impinging in the direction of arrow 22 is inflated obliquely by the plates 20 onto the webs 7 or onto the guide webs 11, so that a strong swirling of the air takes place on the inlet side, which is still caused by the indentations 24 which direct the air upwards. is supported.
  • hemispherical indentations can be provided at a distance from each other, which extend to the center of the single plate or even beyond.
