Plate forming part of a heat exchanger, and heat exchanger comprising at least one such plate

Abstract

The invention relates to a plate ( 105 ) forming part of a heat exchanger and intended to delimit at least one channel ( 111 a, 111 b ) for circulation of a fluid. The plate ( 105 ) comprises a bottom ( 106 ), and at least one raised edge ( 107 ) which surrounds the bottom ( 106 ). The plate ( 105 ) comprises at least one opening ( 110 ) configured to supply the channel ( 111 a, 111 b ) with fluid. The opening ( 110 ) is shaped according to an opening profile (X 1 ). The plate ( 105 ) is equipped with a fluid distribution means ( 300 ) shaped according to a distribution means profile (X 2 ) which is homothetic with the opening profile (X 1 ) of the opening ( 110 ).

1 . A plate forming part of a heat exchanger and configured to delimit at least one channel for circulation of a fluid, the plate comprising:
 a bottom;   at least one raised edge which surrounds the bottom; and,   at least one opening configured to supply the channel with fluid, the opening being shaped according to an opening profile,   wherein the plate is equipped with a fluid distribution means shaped according to a distribution means profile which is homothetic with the opening profile of the opening.   
     
     
         2 . The plate as claimed in  claim 1 , wherein the distribution means is formed integrally with the plate. 
     
     
         3 . The plate as claimed in  claim 2 , wherein the distribution means comprises at least one protrusion which emerges from the bottom toward a first channel. 
     
     
         4 . The plate as claimed in  claim 1 , the opening being shaped as a first circle formed around a first center, wherein the distribution means is shaped as an arc of a circle formed partially around a second center, the second center being coincident with the first center. 
     
     
         5 . The plate as claimed in  claim 3 , wherein the protrusions are in a plurality, two immediately adjacent protrusions being separated by a circulation passage. 
     
     
         6 . The plate as claimed in  claim 1 , further comprising a collar formed around the opening, the distribution means comprising a ring which is in abutment against the collar. 
     
     
         7 . The plate as claimed in  claim 6 , wherein the ring comprises an annulus which is in abutment against the collar, the annulus being provided with at least one crest which extends from the ring toward a first channel ( 111   a ,  211   a ) for the fluid ( 4 ,  6 ). 
     
     
         8 . A tube formed of at least two plates joined together, of which at least one plate configured to delimit at least one channel for circulation of a fluid, the at least one plate comprising:
 a bottom;   at least one raised edge which surrounds the bottom;   at least one opening configured to supply the channel with fluid, the opening being shaped according to an opening profile,   the plate is equipped with a fluid distribution means shaped according to a distribution means profile which is homothetic with the opening profile of the opening.   
     
     
         9 . A heat exchanger comprising at least one tube as claimed in  claim 8 . 
     
     
         10 . The heat exchanger as claimed in  claim 9 , the at least one plate comprising a collar formed around the opening, the distribution means comprising a ring which is in abutment against the collar, wherein the ring comprises a first annular surface (S 1 ) formed by an axial edge of the ring, and a second annular surface formed by a terminal edge of each of the crests, the first annular surface being in contact with the collar of the first plate, while the second annular surface is in contact with the bottom of the second plate.
