Problems solved by technology

With these tubes, it has been noticed that the contact between the tubes and the fins is thus reduced, especially in the concave part of the profile of the tubes, which adversely affects the heat exchange and reduces the performance of the exchanger

Embodiment Construction

[0030] like figure 1 As shown, the invention relates to a heat exchanger 1 of the mechanical type, essentially comprising a bundle of fluid circulation ducts 3 , in which a heat transfer fluid circulates, and comprising heat exchange fins 4 spanned by the fluid circulation ducts 3 . It also specifically comprises two end header tanks 2 spaced apart from each other and connected by a fluid circulation conduit 3 . These pipes are for example aligned in parallel, and the heat exchange fins 4 intended to be parallel to each other are arranged perpendicular to said fluid circulation pipes 3 .

[0031] Briefly, in the case of application as a cooling radiator for a motor vehicle engine, the heat transfer fluid that has come out of the pipes passes through a header tank and is transferred via the supply pipes to the different heat to be cooled of the engine. Components (engine block, cylinder head, etc.), and then reheated, return via a return pipe to the other header of the radiato...

Abstract

The invention relates to a method for manufacturing a heat exchanger, in particular a motor vehicle heat exchanger, in which method a fluid circulation duct (3) is inserted into a through hole in a heat exchange fin (4), and The fluid circulation duct (3) undergoes dilation, enlarging the profile (22) of said duct (3) in order to ensure that the contact with said fins (4) is provided at said through holes, and additionally for said duct ( 3) deforming the concave part (24) of the profile (22) of said one or more ducts (3) in order to deform said through hole accordingly. The invention also relates to a device for carrying out said method and an exchanger obtained by said method.

Description

technical field [0001] The invention relates to a method for producing a heat exchanger and to a heat exchanger obtained by said method. It also relates to a phantom and a duct expansion device for carrying out the method. [0002] In a preferred, but not exclusive application, the associated heat exchanger is intended to be fitted to vehicles as a radiator for cooling the heat engines with which these vehicles are equipped. Background technique [0003] In automotive applications, two main types of heat exchangers are known, the first described as mechanical, comprising exchangers obtained by deforming materials to join their parts, and heat exchangers described as brazed devices, including exchangers obtained by joining parts by brazing. [0004] Mechanical heat exchangers consist essentially of bundles of parallel tubes, arranged in one or more rows, through which a heat transfer fluid (in Applicant's case, glycol-containing water) circulates, and a plurality of fins ,...
