Heat exchanger including spacers

Abstract

A heat exchanger comprising a body provided with a plurality of compartments including at least two end compartments, each compartment defining an internal volume inside which a fluid is capable of flowing, each compartment comprising at least one opening through which a fluid passes to enter or exit said internal volume, is disclosed. The heat exchanger further comprises a separating wall disposed between two adjacent compartments and separating the internal volumes from one another, a closing wall arranged on each of the two end compartments and intended to close the internal end volume of the end compartments, and a plurality of spacers arranged inside the compartments and along the openings, the spacers being capable of maintaining a distance between two adjacent separating walls and/or the spacers being capable of maintaining a distance between the closing wall and the separating wall adjacent to the closing wall.

1 . A heat exchanger comprising:
 a body provided with a plurality of compartments including at least two end compartments, each compartment defining an internal volume inside which a fluid is capable of flowing, each compartment comprising at least one opening through which a fluid passes in order to enter or exit said internal volume,   a separating wall disposed between two adjacent compartments and separating the internal volumes from one another,   a closing wall arranged on each of said at least two end compartments and intended to close the internal end volume of said at least two end compartments, wherein the heat exchanger comprises a plurality of spacers arranged inside the compartments and along the openings, said spacers being capable of maintaining a distance between two adjacent separating walls and/or said spacers being capable of maintaining a distance between the closing wall and the separating wall adjacent to said closing wall.   
     
     
         2 . The heat exchanger according to  claim 1 , further comprising at least one head for distributing the fluid into the compartments, the spacers being located in the vicinity of said at least one head. 
     
     
         3 . The heat exchanger according to  claim 2 , wherein the spacers are arranged substantially at one longitudinal end of the body, said longitudinal end being located at the boundary between the at least one head and the body. 
     
     
         4 . The heat exchanger according to  claim 1 , wherein the spacers are provided with at least one perforation allowing a fluid and/or powder to pass through said spacers. 
     
     
         5 . The heat exchanger according to  claim 1 , wherein the spacers comprise a first face intended to come into contact with a separating wall and a second face opposite the first face, intended to come into contact with another separating wall or a closing wall. 
     
     
         6 . The heat exchanger according to  claim 1 , wherein, in a single compartment, the spacers are arranged side by side and spaced apart by a distance of between 5 and 30 centimeters. 
     
     
         7 . The heat exchanger according to  claim 1 , wherein the spacers are arranged in at least two compartments adjacent to one another, said spacers being substantially aligned one below the other. 
     
     
         8 . The heat exchanger according to  claim 7 , wherein the spacers are arranged in each of said at least two end compartments located at a lower and upper end of said heat exchanger, and spacers are arranged in a compartment adjacent to each of said end compartments. 
     
     
         9 . The heat exchanger according to  claim 1 , wherein the spacers are parallelepipedal in shape. 
     
     
         10 . The heat exchanger according to  claim 1 , wherein the spacers are cylindrical in shape. 
     
     
         11 . The heat exchanger according to  claim 1 , wherein the spacers are elliptical in shape. 
     
     
         12 . The heat exchanger according to  claim 1 , wherein the spacers have a length/width ratio of between 0.5 and 5, preferably between 0.8 and 2. 
     
     
         13 . A heat exchanger, comprising:
 a body comprising a plurality of compartments including a first end compartment and a second end compartment, each compartment defining an internal volume inside which a fluid is capable of flowing, each compartment comprising an opening through which a fluid passes in order to enter or exit the internal volume thereof;   a plurality of separating walls, wherein each separating wall is disposed between two adjacent compartments and separates the internal volumes of the two adjacent compartments from one another;   a first closing wall arranged to close the internal volume of the first end compartment;   a second closing wall arranged to close the internal volume of the second end compartment; and   a spacer capable of maintaining a distance between two adjacent separating walls.   
     
     
         14 . A heat exchanger, comprising:
 a body comprising a plurality of compartments including a first end compartment and a second end compartment, each compartment defining an internal volume inside which a fluid is capable of flowing, each compartment comprising an opening through which a fluid passes in order to enter or exit the internal volume thereof;   a plurality of separating walls, wherein each separating wall is disposed between two adjacent compartments and separates the internal volumes of the two adjacent compartments from one another;   a first closing wall arranged to close the internal volume of the first end compartment;   a second closing wall arranged to close the internal volume of the second end compartment;   a first spacer capable of maintaining a distance between a separating wall and the first closing wall; and   a second spacer capable of maintaining a distance between a separating wall and the second closing wall.
