Embodiment Construction

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

[0029] The heat exchanger 1 comprises walls 2 , 3 , 4 which, when assembled, form an outer shell or casing presenting the outer walls of said heat exchanger 1 . Wall 3 forms the upper part of the heat exchanger 1 , wall 5 forms the base of said heat exchanger 1 and walls 2 , 4 form the lateral parts of said heat exchanger 1 .

[0030] Inside the housing, the heat exchanger houses an exchanger bundle allowing heat exchange between the first and second fluids. The exchanger bundle comprises rows of tubes 30 stacked substantially parallel to one another so as to form a stack 31 .

[0031] At both ends of the stack 31 of pipes 30 , the stack 31 of pipes 30 is connected to two headers 60 having multiple functions. As such, the header 60 can receive and hold the different conduits 30 of the sta...

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

technical field [0001] The invention relates to a header for an exchanger bundle of a heat exchanger, such as a heat exchanger designed for a motor vehicle. The header according to the invention is particularly suitable for resisting high pressures. Background technique [0002] A heat exchanger of the type used in the motor vehicle industry consists in principle of a housing or casing comprising, inside it, a heat exchange element allowing heat to be exchanged from a first fluid to a second fluid. The elements allowing this heat exchange may for example comprise pipes. [0003] The tubes located within the heat exchanger may be present within an exchanger bundle comprising a plurality of tubes arranged substantially parallel to each other. The pipes can be positioned in one row or in multiple rows parallel to each other. The pipes are held at their respective ends on the first and second headers. The duct makes it possible to guide the first fluid within said duct from ...
