Definitions

  • the invention relates to the field of plate heat exchangers between which circulate two fluids brought to different temperatures and one of which receives / discharges the heat energy of the other.
  • the invention relates more particularly to large-size plate heat exchangers, the frame of which has inside a guide rail making it possible to guide the plates parallel to the interior of the frame before carrying out the clamping of the plates on one another. to ensure the seal between the two circuits.
  • a peripheral seal is positioned on each of the plates of the exchanger.
  • Such plates equipped with peripheral sealing gaskets are in particular described in the document GB-1,592,069 .
  • the aim of the invention is therefore to eliminate the offset which may occur between the different plates of a heat exchanger when positioning the plates in the frame and then when the plates are clamped against each other.
  • this objective is achieved without degrading the sealing function performed by the peripheral seal.
  • the invention therefore relates to a heat exchanger comprising a set of plates defining between them fluid circuits circulating alternately by means of seals attached between each pair of two adjacent plates.
  • Each plate comprises at least one guide cutout formed at at least one of its ends and which makes it possible to guide each plate inside a frame.
  • the seals ensure the tightness of the volume defined between each pair of adjacent plates, each of the seals having an upper surface facing one of said two adjacent plates, the upper surface having, before compression between said two adjacent plates, a portion in point and a concave portion on either side of the point.
  • the heat exchanger is characterized in that it also comprises between each pair of two adjacent plates, and near the guide cutout, at least one spacer intended to be compressed and arranged in contact with the two plates. adjacent.
  • Each spacer prevents any tilting of one plate relative to the other during tightening and has, before compression, a thickness at least equal to that of the seal.
  • the plates are all arranged parallel to each other and no offset can occur, even when pressurizing the seal since the spacer positioned close to the guide cutout prevents tilting of one plate relative to the other.
  • each spacer can be inserted in a groove formed in one of the plates with which it comes into contact.
  • the spacer can be positioned, or even glued, inside a groove making it possible to prevent the spacer from slipping during tightening in particular.
  • These grooves are generally made by means of a press and a stamp during the forging operation of the plates to generate a plurality of corrugations and thus increase the surface area of the heat exchange between the fluids inside the plate. 'interchange.
  • each spacer may have a substantially rectangular parallelepiped shape. In this way, it has two parallel faces, and it has a constant section compatible with a manufacturing process such as extrusion or molding.
  • each spacer may have a compressibility greater than that of the seal.
  • the spacer which has a thickness greater than that of the seal, is able to compress without hindering the subsequent compression of the seal.
  • such a spacer can be produced in different ways and may or may not be secured to the seal.
  • Each spacer is a protuberance of the seal.
  • the seal and the spacer form a monolithic assembly which can be produced in a single operation, in particular by a molding process.
  • the heat exchanger further comprises a connecting portion between each seal and each spacer.
  • This configuration makes it possible to position the spacer close to the guide cutout, without however modifying the position of the seal on the plate.
  • the function of this connecting portion is only to facilitate the manufacture of the exchanger by avoiding increasing the number of parts constituting it as well as the positioning of the spacer on the plate.
  • This connecting portion has a thickness less than that of the seal, and therefore that of the spacer as well.
  • Each spacer can be separated from the seal. In this way, it is possible to arrange each of the elements on a plate independently. Such a variant therefore makes it possible to eliminate the connecting portion and to use the existing seals in conventional heat exchangers already manufactured.
  • seals and the spacers can be envisaged and in particular they can be made from different materials or not.
  • the spacers and the seals can be made of the same material.
  • they can for example be molded in the same mold and manufactured simultaneously.
  • the spacers and the seals can be made from two different materials. In this way, it is in particular possible to adapt the compressibility of the spacers so as not to locally modify the compressibility of the seal.
  • the invention relates to a heat exchanger (1) as shown in figure 1 .
  • This type of plate heat exchanger (10) thus comprises two fluid circuits (2, 3) in which two fluids circulate to exchange their heat energy.
  • these circuits (2, 3) are delimited by a seal (4) defining the periphery of the exchange zone on each plate.
  • the plates (10) are positioned inside a frame (6) and are guided in this frame by means of a guide cutout (5) cooperating with a rail attached to the frame (6).
  • Spacers (7) then make it possible to position each plate (10) at an equal distance from one another and in parallel near this guide rail.
  • the spacers (7) make it possible to ensure the parallel positioning of the plates with respect to each other before the tightening operation aimed at compressing the seal (4).
  • the spacers (7) can form a protuberance of the seal (4). This embodiment makes it possible to facilitate the assembly and manufacturing operations of such an exchanger (1).
  • the spacers (17) can also be separate from the seal (4).
  • the spacers (17) can also be separate from the seal (4).
  • the spacer (7) is in this case a protuberance of the seal (4) and is linked to the latter by means of a connecting portion (9). Furthermore, the thickness (E) of the spacer (7) is greater than the thickness (e) of the seal (4). In this way, an upper face (27) of the spacer (7) first comes into contact with the upper plate (11) during the positioning of the plates (10,11) facing each other in the frame (6).
  • a gasket having a thickness e of 6 mm combined with a spacer having a thickness E of 6.2 mm can be used.
  • a lower face (37) of the spacer (7) cooperates with a groove (8) so as to facilitate the positioning and securing of the spacer (7) on the plate (10).
  • the spacer (7) must be very precisely positioned on the plate (10) so as to cooperate with a flat surface on the back of the facing plate (11).
  • the upper (27) and lower (37) faces are, in the variant shown, substantially planar so as to form a spacer (7) of substantially rectangular parallelepiped shape.
  • the upper (27) and lower (37) faces can also form a left surface of concave shape before compression.
  • the contact between the spacer (7) and the adjacent plate (11) is linear before becoming surface.
  • Such a line contact near the guide rail makes it possible to guarantee the parallel positioning of the plates relative to each other.
