Header for exchanger bundle of a heat exchanger

Abstract

The present invention relates to a header usable with an exchanger bundle of a heat exchanger. Said exchanger bundle includes at least one first row of tubes and one second row of tubes. The tubes are suitable for enabling the flow of a first fluid in the exchanger bundle. The header includes at least: —one first contact element for supporting the top side of a first end of the first row of tubes; —one second contact element for supporting the bottom side of said first end of the first row of tubes and supporting the top side of a first end of the second row of tubes, the thickness of the second contact element defining the distance between said first and second rows of tubes; and —one third contact element for supporting the bottom side of said first end of the second row of tubes.

1 . A header which is designed to be used with an exchanger bundle of a heat exchanger, said exchanger bundle comprising:
 at least a first row of tubes and a second row of tubes, the tubes being designed to permit the circulation of a first fluid in the exchanger bundle−, the header comprising at least:
 a first contact element to retain the upper side of a first end of the first row of tubes; 
 a second contact element to retain the lower side of said first end of the first row of tubes, and in order to retain the upper side of a first end of the second row of tubes, the thickness of the second contact element defining the distance between said first and second rows of tubes; and 
 a third contact element to retain the lower side of said first end of the second row of tubes, 
 wherein: 
 the first, second and third contact elements are equidistant, 
 the first end of the first contact element is connected to the first end of the second contact element by at least a first bent connector, and 
 the second end of the second contact element is connected to the second end of the third contact element by at least a second bent connection element. 
   
     
     
         2 . The header as claimed in  claim 1 , wherein said header comprises metal such as aluminum. 
     
     
         3 . The header as claimed in  claim 2 , wherein the material of said header comprises plated aluminum. 
     
     
         4 . A plate made of a bendable material comprising bending elements, said plate being configured such that, when the plate is bent by means of connection elements, the plate forms a header as claimed in  claim 1 .
