Embodiment Construction

[0033] Such as figure 1 As shown, the invention relates to a heat exchanger 1 which allows heat exchange between a first fluid, in particular a liquid coolant C, and a second fluid, which will be called fluid G to be cooled, eg gas. It may be a charge air cooler, inside which a stream of compressed air intended to supply an internal combustion engine, such as a motor vehicle engine, is cooled by a liquid coolant, in particular a mixture of water and glycol.

[0034] The exchanger 1 comprises a heat exchange core 2 comprising a stack of plates 4 intended to allow heat exchange between a fluid G to be cooled and a liquid coolant C circulating in contact with the plates 4 . The plates 4 define between them alternating circuits 6 , 8 for the fluid G to be cooled and the liquid coolant C. The core bundle 2 has the general shape of a parallelepiped, with an inlet face 10 for the fluid G to be cooled and an opposite outlet face (not shown). On the other side of the stack it ends in...

Abstract

A heat exchanger (1) comprises a plurality of stacked plates (4, 12, 14) inside a box (5). The plurality of stacked plates (4, 12, 14) enable an exchange of heat between a first and a second fluid (C, G) circulating in contact with the plurality of stacked plates (4, 12, 14). The plurality of stacked plates (4, 12, 14) comprise a stress area (70) intended to withstand heat variations that may cause mechanical stress. The heat exchanger (1) further comprises a reinforcement (71) that is in contact with the stress area (70) and the box (5).

Description

technical field [0001] The present invention relates to stacked plate heat exchangers. [0002] The invention applies to any type of heat exchanger, especially for a motor vehicle, for example an exchanger intended to be installed in the engine compartment of the vehicle, such as a charge air cooler (CAC) or engine exhaust gas recirculation Cooler, also called EGR exchanger (or EGRC). Background technique [0003] In this field, heat exchangers are known comprising a heat exchange core comprising a series of plates stacked in parallel one on top of the other. The stacked plates form heat exchange surfaces between which the fluid to be cooled and the cooling fluid circulate in alternating layers through fluid circulation circuits, spacers may be provided to improve the heat exchange between the fluid to be cooled and the cooling fluid . The stack of plates is thus configured to define two distinct circuits: that of the fluid to be cooled and that of the cooling fluid. [...
