Definitions

  • the present invention relates to a plate heat exchanger.
  • the plate heat exchangers are generally formed by an elongate sealed enclosure and a plate bundle disposed in said sealed enclosure and forming therewith a free space.
  • the plate bundle is composed of a stack of plates parallel to each other and forming between them a dual circulation circuit of two independent fluids and generally against the current.
  • This type of heat exchanger also comprises an inlet pipe of a hot fluid connected by a connection box also called collector, directly to the input of the first circuit of the plate bundle, which circulates in one of the circuits. this beam, and an outlet pipe of the cooled fluid after passing through said plate bundle and which is connected by a junction box directly to the output of this first circuit.
  • the heat exchangers of this kind also comprise an inlet pipe for a cold fluid circulating in the other of the plate bundle circuits and which is connected directly by a connection box to the inlet of the second circuit of this plate bundle and an outlet pipe of this heated fluid after passing through said bundle of plates.
  • This outlet pipe of the heated fluid is also connected directly by a junction box to the output of the second circuit of the plate bundle.
  • the heat exchange between the hot and cold fluids along the plate bundle subjects the wall of the enclosure to temperature variations along its length. Indeed, at the inlet of the hot fluid, the wall of the chamber is subjected to a high temperature, while the temperature gradually decreases along the wall as a function of the cooling of the hot fluid in the plate bundle.
  • the enclosure is generally formed of several ferrules placed end to end and assembled together in particular by welding. Given the variations in temperature, each shell has up to now a different thickness and determined according to the temperature to which it is subjected, see for example the document WO 94/21979 .
  • the object of the invention is to propose a plate heat exchanger which avoids these drawbacks and which makes it possible to have an enclosure of constant thickness over its entire length.
  • a plate heat exchanger generally designated by the reference 1 and which comprises, on the one hand, a sealed enclosure 2 of elongate shape and arranged for example vertically and, on the other hand, a bundle of plates 3 placed in said chamber 2 and forming with it, around said beam, a free space 4.
  • the plate bundle 3 of parallelepipedal general shape consists of a stack of plates, not shown, parallel to each other and between them a dual circuit A and B circulation of two independent fluids and for example against the current.
  • the heat exchanger 1 also comprises an inlet pipe 10 for a hot fluid directly connected by a connection box 11 also called a collector at the inlet A1 of the first circuit A of the plate bundle 3 and an outlet pipe 12 of the cooled fluid after its passage in the plate bundle 3 and which is connected directly by a junction box 13 to the output A2 of said first circuit A.
  • a connection box 11 also called a collector at the inlet A1 of the first circuit A of the plate bundle 3
  • an outlet pipe 12 of the cooled fluid after its passage in the plate bundle 3 and which is connected directly by a junction box 13 to the output A2 of said first circuit A.
  • the heat exchanger 1 also comprises an inlet pipe 20 for a cold fluid which communicates with the inlet B1 of the second circuit of the plate bundle via the free space 4 formed between the bundle of plates 3 and the enclosure 2.
  • the input B1 of the second circuit B is situated opposite the input A1 of the first circuit A of the plate bundle 3.
  • the heat exchanger 1 also comprises a tube 21 for outputting the heated fluid after passing through the second circuit B of the plate bundle 3 and which is connected to the output B2 of this second circuit B via a connection box 22.
  • the cold fluid flows from bottom to top of the plate bundle 3.
  • inlet pipes 10 of the hot fluid, inlet 20 of the cold fluid and outlet 21 of the heated fluid are disposed at the same end of the enclosure 2 and, in the embodiment shown in this figure, at the upper end of this enclosure 2.
  • the plate heat exchanger 1 comprises means 25 for channeling the cold fluid along the inner wall of the chamber 2 between the inlet pipe 20 of this cold fluid and the inlet B1 of the second circuit B of the beam. plates 3.
  • these means for channeling the cold fluid comprise an inner envelope 25 which comprises a first wall 26 disposed above the input A1 of the circuit A and the output B2 of the circuit B and a second wall 27 disposed in the free space 4 between the chamber 2 and the plate bundle 3 and forming with the inner wall of the chamber 2, an annular passage 5 for the cold fluid.
  • the first wall 26 is flat.
  • This wall 26 may have other shapes, such as a hemispherical or conical shape to promote the circulation of cold fluid in the annular passage 5.
  • the cold fluid circulates in the annular passage 5 along the inner wall of the chamber 2 and thus cools this enclosure 2.
  • the wall 27 of the inner casing 25 extends over a part of the length of the plate bundle 3 so as to direct the cold fluid circulating in the annular passage 5 to the inlet B1 of the second circuit B of the plate bundle 3, as represented by the arrows F on the Fig. 1 .
  • Maintaining the inner casing 25 is ensured for example by welding the wall 26 on the inlet pipe 10 and on the outlet pipe 21.
