Description

ECHANGEUR THERMIQUE  HEAT EXCHANGER
La présente invention concerne un échangeur thermique. The present invention relates to a heat exchanger.
Elle se rapporte plus précisément à un échangeur thermique comportant au moins un tube et un collecteur, ledit collecteur étant pourvu d'au moins un alésage de réception de l'extrémité du tube.  It relates more specifically to a heat exchanger comprising at least one tube and a collector, said collector being provided with at least one receiving bore of the end of the tube.
Par « tube », il est ici entendu un élément plat allongé en forme de lamelle comprenant au moins un canal longitudinal, en général plusieurs canaux longitudinaux juxtaposés sur la largeur de la lamelle.  By "tube" is meant here an elongate dish-shaped element comprising at least one longitudinal channel, generally several longitudinal channels juxtaposed over the width of the strip.
Un tel échangeur thermique est décrit dans le document de brevet US 2003/0155109.  Such a heat exchanger is described in US patent document 2003/0155109.
Selon ce document, chaque tube est pourvu à ses extrémités de deux déformations assurant la formation d'épaulements de butée contre la face externe des collecteurs, lorsqu'elle est introduite et fixée dans l'alésage correspondant du collecteur.  According to this document, each tube is provided at its ends with two deformations ensuring the formation of abutment shoulders against the outer face of the collectors, when it is inserted and fixed in the corresponding bore of the collector.
Un tel agencement nécessite un usinage des alésages et des tubes avec des côtes très précises, afin d'assurer une communication étanche du ou des canaux longitudinaux des tubes et du ou des canaux longitudinaux d'un collecteur et surtout d'éviter une déformation du ou des canaux longitudinaux des tubes, une fois ces dernières mise en places dans les alésages du collecteur.  Such an arrangement requires the machining of bores and tubes with very precise ribs, in order to ensure tight communication of the longitudinal channel or channels of the tubes and of the longitudinal channel or channels of a collector and especially to avoid deformation of the longitudinal channels of the tubes, once the latter placed in the bores of the collector.
L'invention résout ce problème en proposant un échangeur thermique dont le collecteur est de préférence réalisé par extrusion ou par usinage et supprimant la nécessité de réalisation de ces épaulements sur les tubes.  The invention solves this problem by proposing a heat exchanger whose collector is preferably made by extrusion or by machining and eliminating the need for making these shoulders on the tubes.
Pour ce faire, l'invention propose un échangeur thermique comportant au moins un tube et un collecteur, ledit collecteur étant pourvu d'au moins un alésage de réception de l'extrémité du tube caractérisé en ce que ledit alésage de réception comporte au moins une partie de butée de l'extrémité correspondante dudit tube. Selon un mode de réalisation, ladite partie de butée est disposée à une extrémité latérale dans ledit alésage de réception du collecteur. To do this, the invention proposes a heat exchanger comprising at least one tube and a collector, said collector being provided with at least one receiving bore of the end of the tube characterized in that said receiving bore comprises at least one abutment portion of the corresponding end of said tube. According to one embodiment, said abutment portion is disposed at a lateral end in said collector receiving bore.
Avantageusement, ladite partie de butée comporte au moins une nervure disposée latéralement dans l'alésage de réception du collecteur.  Advantageously, said abutment portion comprises at least one rib disposed laterally in the receiving bore of the collector.
De préférence, ledit collecteur comporte au moins deux canaux longitudinaux disposés près des bords longitudinaux du collecteur, unedite nervure étant disposée à chaque fois dans un dit canal longitudinal du collecteur disposé près des bords longitudinaux du collecteur.  Preferably, said collector comprises at least two longitudinal channels disposed near the longitudinal edges of the collector, a said rib being disposed each time in a said longitudinal channel of the collector disposed near the longitudinal edges of the collector.
Selon une variante, ledit collecteur comporte un canal d'écoulement transversal connecté à au moins un canal transversal de liaison transversal audit canal d'écoulement et débouchant dans lesdits alésages de réception et ladite partie de butée est en partie supérieure et/ou inférieure dans lesdits alésages du collecteur.  According to a variant, said manifold comprises a transverse flow channel connected to at least one transverse connecting channel transverse to said flow channel and opening into said receiving bores, and said abutment portion is in upper part and / or lower in said bores of the collector.
Deux dits tubes peuvent être reçus dans chaque dit alésage de réception.  Two said tubes can be received in each said receiving bore.
Ledit collecteur peut être composé d'au moins deux parties, à savoir une partie dite plaque collectrice comportant au moins un alésage de réception d'au moins une extrémité d'un tube et une partie dite boîte collectrice comportant des canaux longitudinaux.  Said collector may be composed of at least two parts, namely a so-called collecting plate part comprising at least one receiving bore of at least one end of a tube and a so-called collecting box comprising longitudinal channels.
Ledit collecteur peut être en métal, de préférence en aluminium. Lorsque ledit collecteur est réalisé par extrusion, ladite partie de butée est de préférence obtenue par ladite extrusion.  Said collector may be metal, preferably aluminum. When said collector is made by extrusion, said abutment portion is preferably obtained by said extrusion.
Ledit collecteur peut être réalisé par extrusion selon son axe transversal.  Said collector can be made by extrusion along its transverse axis.

Lors de son utilisation, le fluide rentre dans l'échangeur par un premier collecteur dit d'alimentation et parcourt les canaux 2A de ce collecteur. Par la suite, ce fluide circulera dans les tubes 1, puis sera évacué par un second collecteur dit d'évacuation.  During its use, the fluid enters the exchanger by a first so-called feed collector and runs through the channels 2A of this collector. Thereafter, this fluid will circulate in the tubes 1, then will be evacuated by a second so-called evacuation collector.
