Heat exchanger

Abstract

The present invention relates to a heat exchanger for exchanging heat between first and second fluids, said exchanger including: a casing and an exchange bundle positioned inside said casing, wherein the exchange bundle includes: a main surface which has a main width and which consists of a plurality of tubes suitable for guiding the first fluid inside said tubes; an intake of the first fluid toward an outlet of the first fluid, making it possible to guide, outside of said tubes, the second fluid; an intake of the second fluid toward an outlet of the second fluid; wherein the tubes are, at least at one first end, assembled such as to form a secondary surface having a secondary width which is smaller than the main width for coupling with the intake and/or the outlet of the first fluid; wherein the secondary surface at the first end of the tubes is formed such as to create a space between the casing and the outer surface of the secondary surface, said space being connected to the intake and/or the outlet of the second fluid.

1 . A heat exchanger allowing exchange of heat between a first and a second fluid, said exchanger comprising:
 a case and   an exchange bundle positioned inside said case,   wherein the exchange bundle comprises:
 a main surface comprising a main width and formed with a plurality of tubes suitable for guiding the first fluid inside these tubes, 
 an inlet for the first fluid towards an outlet of the first fluid and allowing outside these tubes guidance of the second fluid, 
 an inlet for the second fluid towards an outlet of the second fluid, 
   wherein the tubes are, at at least one first end, assembled in order to form a secondary surface comprising a secondary width less than the main width for connection to the inlet and/or the outlet of the first fluid,   wherein the secondary surface at the first end of the tubes is formed for generating a space between the case and the outer face of the secondary surface, which space is connected to the inlet and/or the outlet of the second fluid.   
     
     
         2 . The heat exchanger according to  claim 1 , wherein the tubes are, at a first end assembled in order to form the secondary surface for connection to the inlet of the first fluid
 wherein the secondary surface at the first end of the tubes is formed for generating a space between the case and the outer face of the secondary surface, which space is connected to the outlet of the second fluid;   and wherein the tubes are, at the second end, assembled in order to form a secondary surface comprising a secondary width less than the width for connecting to the outlet of the first fluid, said secondary surface at the second end of the tubes generating a space between the case and the outer face of the secondary surface, which space is connected to the inlet of the second fluid.   
     
     
         3 . The heat exchanger according to  claim 1 , wherein said heat exchanger comprises a sealing element giving the possibility of covering the tubes at least at one end. 
     
     
         4 . The heat exchanger according to  claim 1 , wherein said heat exchanger comprises a connecting element giving the possibility of connecting at least one end of the tubes to an inlet or to an outlet by means of said connecting element. 
     
     
         5 . The heat exchanger according to  claim 1 , wherein the tubes are positioned relatively to each other so as to create channels between them, said channels include disturbers. 
     
     
         6 . The heat exchanger according to  claim 1 , wherein the exchange bundle is obtained by means of a plurality of plates positioned over each other and wherein the ends of said plates are provided with a rim giving the possibility of increasing the surface area between the plate and the inside of the case.
