Embodiment Construction

[0016] In the various figures, the same elements have similar reference numerals.

[0017] For the exchange plate 1 of the flat tube 100 of the heat exchanger, in figure 1 shown in , can be made from pressed sheet metal. It comprises a fluid inlet 3a and a fluid outlet 3b. The pressing of the exchange plate 1 forms cavities in which the ribs 7 define a flow circuit for fluid to flow between the fluid inlet 3a and the fluid outlet 3b.

[0018] The ribs 7 give the flow circuit a path for the first heat transfer fluid to circulate between the fluid inlet 3a and the fluid outlet 3b. The flow path comprises at least two straight passages 5 connected by a bend 9 . This flow path allows for an increase in the length of the flow circuit and thus increases the time for the first heat transfer fluid to flow within the flow circuit, thereby increasing the time for heat transfer to the second fluid that can circulate on the opposite face of the exchange plate 1 length. To facilitate ...

Abstract

Flat tube (100) of a charge air cooler, which tube is produced from at least one metal sheet that is pressed so as to form a heat exchange plate (1), said pressing allowing a connection between a fluid inlet and a fluid outlet via a circuit through which heat transfer fluid passes, said circuit comprising at least one metal insert (51) positioned within it and made of a material that creates a potential difference of 30mV or greater with the material of the flat tube (100).

Description

technical field [0001] The present invention relates to the field of heat exchangers and more particularly to the field of charge air heat exchangers for the automotive sector. Background technique [0002] In the automotive field, it is known practice to use a heat exchanger comprising a stack of identical flat tubes through which the first fluid circulates. Each flat tube is generally formed from two sheet metal plates pressed so as to form a disc in a predetermined pattern and arranged such that their recesses face each other. The two plates are then joined together in a fluid-tight manner, thereby forming a flat tube through which the first fluid can communicate from a fluid inlet to a fluid outlet, each at one end of the flat tube, And more typically each are on opposite sides of the plate. [0003] The flat tubes are stacked one on top of the other and the fluid inlets of each flat tube are joined together to form an inlet riser. Likewise, the fluid outlets of each ...
