Embodiment Construction

[0028]FIG. 1 represents, according to an exploded view, a first embodiment of a heat exchanger 1 comprising at least one header 60 for an exchanger bundle 10 according to the present invention.

[0029]The heat exchanger 1 comprises walls 2, 3, 4 which, when assembled, form a casing or housing representing the outer wall of said heat exchanger 1. The wall 3 forms the upper part of the heat exchanger 1, the wall forms the base of said heat exchanger 1, and the walls 2, 4, form the lateral parts of said heat exchanger 1.

[0030]Inside the casing, the heat exchanger contains an exchanger bundle which permits an exchange of heat between a first and a second fluid. The exchanger bundle comprises rows of tubes 30 which are stacked in a manner substantially parallel to one another, in order to form a stack 31.

[0031]At its two ends, the stack 31 of tubes 30 is connected to two headers 60 with a plurality of functions. Thus, the headers 60 can receive and retain the different tubes 30 of the stac...

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.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a header for an exchanger bundle of a heat exchanger, such as a heat exchanger which is designed for motor vehicle. The header according to the present invention is particularly suitable for withstanding high pressures.PRIOR ART[0002]A heat exchanger of the type used in the motor vehicle industry in principle comprises a casing or housing comprising in its interior heat exchange elements which permit the exchange of heat from a first fluid to a second fluid. These elements which permit this exchange of heat can for example comprise tubes.[0003]The tubes situated inside a heat exchanger can be present within an exchanger bundle comprising a plurality of tubes arranged substantially parallel to one another. The tubes can be positioned in a row or a plurality of rows which are parallel to one another. The tubes are retained at their respective ends on a first and a second header. The tubes make it possible to guide the first ...
