Embodiment Construction

[0039] The present invention is applied, for example, in figure 1 shown in the heat exchanger. The exchanger is in particular a condenser of an air-conditioning circuit inside the vehicle.

[0040] The heat exchanger 1 may comprise a tube bundle of parallel tubes 2, the ends 2A of which are connected in a fixed and sealed manner to a manifold for inlet 3 and outlet respectively according to the direction of circulation F of the coolant fluid circulating in the tubes 2 4. These inlet 3 and outlet 4 manifolds comprise an inlet flange 5 and an outlet flange 6 which are themselves connected to an inlet connection 8 and an outlet connection 9 which fit on the connection part and allow the fluid Execute the loop.

[0041] In particular, the tubes 2 in which the fluid circulates have a flattened cross-section and between the tubes are provided guides 7 which increase the gap between the fluid circulating in the exchanger 1 and the flow of external air passing through the exchanger...

Abstract

The invention relates to a header box (3') comprising a header (10) and a cover (11) having a longitudinal extent dimension and at least one flange (8') crimped in-between the header (10) and the cover (11). According to the invention: the header (10) has a ductility different from that of the flange (8'); at said flange (8'), a longitudinal portion (18) of the header (10) and / or of the flange (8') is rolled in such a way that the flange (8') is trapped between the header (10) and the cover (11). The invention also relates to a heat exchanger comprising such a box and to a method of crimping such a box.

Description

[0001] This application is a divisional application with the application number 201280025554.6, titled "manifold, heat exchanger including said main pipe, and method for coiling this type of main pipe", and the filing date is May 22, 2012. [0002] field of invention [0003] The invention relates to a manifold comprising a header, a cover and at least one flange, a heat exchanger comprising said manifold and a method for crimping a manifold of this type. [0004] The invention applies to any type of heat exchanger, in particular for motor vehicles, such as for example an air conditioning circuit. Background technique [0005] In the field, exchangers are known comprising bundles of tubes arranged parallel to each other in one or more rows parallel to each other, these tubes being designed to transport a coolant fluid, while air flows between the tubes and exchanges with the coolant fluid heat exchange. [0006] The tubes are connected to the manifolds, ie the input manifold...
