Multichannel tube heat exchanger, in particular for motor vehicle
First Claim
1. A heat exchanger, in particular an evaporator, comprising a bank of tubes mounted between two fluid chambers by means of respective manifolds and suitable for being traversed by a fluid, wherein the tubes (10) each include several channels (12) separated by at least one longitudinal partition (68) and are arranged along a single row, parallel to two large faces (F1, F2) of the exchanger, wherein the circulation of the fluid takes place in at least two layers (SN1, SN2;
- SN3, SN4) parallel to the large faces of the exchanger and each formed by a part (G1;
G2) of the channels (12) of the tubes, and wherein at least one of the fluid chambers (28, 46) comprises an internal longitudinal partition (48, 68) suitable for dividing the manifold chamber into at least two longitudinal compartments communicating respectively with the two layers.

Abstract
The invention concerns a heat exchanger comprising an array of tubes (10) mounted between two fluid boxes (28, 46) via respective manifolds (16) and designed to be run through by a fluid. The tubes (10) comprise each several channels separated by at least a longitudinal partition and are arranged in a single row, parallel to tow large surfaces of the exchanger, such that the fluid circulation takes place in at least two layers parallel to the large surfaces of the exchanger and formed each by part of tube channels. One at least of the fluid boxes (28, 36) comprises an internal longitudinal partition dividing the fluid box into at least two longitudinal sections communicating with the two layers respectively. The invention is in particular applicable to air conditioning evaporators.
