Embodiment Construction

[0037] In these figures, substantially the same elements have the same reference numerals.

[0038] Figure 1 shows a heat exchanger 1, in particular for a motor vehicle.

[0039] This exchanger is intended to be arranged in the engine air supply circuit.

[0040] Such an exchanger 1 is particularly configured to cool supercharged air for a combustion engine of a motor vehicle.

[0041] The exchanger 1 comprises a core bundle of tubes or plates for heat exchange between a first fluid, such as supercharged air, and a second fluid, such as liquid coolant.

[0042] This core bundle of tubes or plates is accommodated in a housing 3 .

[0043] The exchanger 1 also comprises a first header tank 5 for the first fluid inlet, and a second header tank 7 for the fluid outlet.

[0044] According to the embodiment shown, the outlet box 7 is fixed to the cylinder head of the engine (engine not shown) to allow the entry of cooled air and thus forms an inlet box for the first fluid.

Abstract

The invention relates to a heat exchanger, in particular for a motor vehicle, comprising: - an array for heat transfer between fluids, - a casing (3) for containing said array, - A container (5) for collecting incoming fluid, and - a container (7) for collecting outgoing fluid, characterized in that said housing has at least one inlet collecting container (5) adjacent to said at least one inlet collecting container (5) for absorbing stress area, making it resistant to mechanical stress exerted on said housing (3) as said fluid flows in said array from said fluid inlet (5) container to said fluid outlet (7) container.

Description

technical field [0001] The invention relates to heat exchangers, in particular for motor vehicles. [0002] More specifically, the invention relates to heat exchangers for motor vehicle engine air supply circuits. [0003] The present invention relates to the general field of air supply to motor vehicle engines, and more specifically to engines whose charge air comes from a compressor or a turbocharger, so it is called supercharged air. Background technique [0004] It is known practice to cool the supercharge air leaving the compressor by means of a heat exchanger, also known as a charge air cooler (or CAC for short). [0005] In this case, the CAC heat exchanger allows the overcharged engine charge air to be cooled by exchanging heat with another fluid, such as external air or a liquid, such as water from the engine cooling circuit, thereby forming an air / Air or liquid / air type exchangers. [0006] Such exchangers generally comprise a heat exchange core comprising stac...
