Definitions

  • the present invention relates to a heat exchanger plates.
  • Plate heat exchangers are generally formed by an elongated waterproof enclosure and a plate bundle disposed in said sealed chamber and providing a free space therewith.
  • the plate bundle is composed of a stack of parallel plates to each other and between them a double circulation circuit of two independent and usually countercurrent fluids.
  • This type of heat exchanger also includes a inlet pipe of a hot fluid connected by a connection box also called collector, directly at the entrance of the first circuit of the plate bundle, which circulates in one of the circuits of this bundle, and a outlet pipe of the cooled fluid after passing through said beam of plates and which is connected by a connection box directly to the output of this first circuit.
  • a connection box also called collector
  • the heat exchangers of this kind also include an inlet manifold of a circulating cold fluid in the other circuits of the plate bundle and which is connected directly by a box for connection to the input of the second circuit of this plate bundle and an outlet pipe of this heated fluid after passing through said beam of plates.
  • This outlet pipe of the heated fluid is also connected directly by a connection box at the output of the second circuit of the beam of plates.
  • Thermal exchange between hot and cold fluids along the plate bundle subjects the enclosure wall to variations in temperatures along its length. Indeed, at the inlet of the hot fluid, the wall of the enclosure is subjected to a high temperature, while the temperature decreases gradually along this wall as a function of cooling the hot fluid in the plate bundle.
  • the enclosure is usually formed of several ferrules placed end to end and assembled together by welding. take in account the temperature variations, each ferrule has so far a thickness different and determined according to the temperature to which it is subjected.
  • the object of the invention is to propose a heat exchanger for plates that avoids these disadvantages and allows to have a speaker of constant thickness throughout its length.
  • FIG. 1 there is shown a plate heat exchanger designated as a whole by reference 1 and which includes, on the one hand, a watertight enclosure 2 of elongated shape and disposed for example vertically and, on the other hand, a plate bundle 3 placed in said chamber 2 and gentle with it, around said beam, a free space 4.
  • a plate heat exchanger designated as a whole by reference 1 and which includes, on the one hand, a watertight enclosure 2 of elongated shape and disposed for example vertically and, on the other hand, a plate bundle 3 placed in said chamber 2 and gentle 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 to the others and between them a double circuit A and B of circulation of two independent fluids and for example against the current.
  • the heat exchanger 1 also comprises a tubing 10 input of a hot fluid directly connected by a connection box 11 also called collector at the A1 input of the first circuit A of the beam of plates 3 and a tube 12 for the outlet of the cooled fluid after its passage through the bundle of plates 3 and which is connected directly by a box of connection 13 to the output A2 of said first circuit A.
  • a connection box 11 also called collector at the A1 input of the first circuit A of the beam of plates 3
  • a tube 12 for the outlet of the cooled fluid after its passage through the bundle of plates 3 and which is connected directly by a box of connection 13 to the output A2 of said first circuit A.
  • the heat exchanger 1 also comprises a pipe 20 input of a cold fluid which communicates with the input B1 of the second circuit of the plate bundle through the free space 4 formed between the plate bundle 3 and enclosure 2.
  • Input B1 of second circuit B is located opposite the input A1 of the first circuit A of the plate bundle 3.
  • the heat exchanger 1 also comprises a pipe 21 outlet of 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 by a connecting 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 arranged 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 of 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 plate bundle 3.
  • these fluid channeling means cold include an inner casing 25 which includes a first wall 26 disposed above the A1 input of the circuit A and the B2 output of the circuit B and a second wall 27 disposed in the free space 4 between the enclosure 2 and the plate bundle 3 and arranging with the inner wall of this chamber 2, a annular passage 5 for the cold fluid.
  • the first wall 26 is flat. This wall 26 may have other shapes, such as example a hemispherical or conical shape to promote the circulation of the cold fluid in the annular passage 5.
  • the cold fluid circulates in the annular passage 5 along the wall internal of the chamber 2 and thus cooling the enclosure 2.
  • the wall 27 of the inner envelope 25 extends over a portion of the length of the beam of plates 3 so as to direct the cold fluid circulating in the annular passage 5 to the input B1 of the second circuit B of the plate bundle 3, as shown by the arrows F in FIG. 1.
  • the maintenance of the inner casing 25 is ensured for example by the welding of the wall 26 on the inlet pipe 10 and on the outlet pipe 21.
  • the circulation of cold fluid along the inner wall of the chamber 2 makes it possible to cool the chamber 2, which has the advantage of to be able to make this enclosure 2 with ferrules, not shown, placed end-to-end and each having the same thickness facilitating, therefore, assembling these ferrules together and reducing the cost of manufacturing and realization of this enclosure.
