Abstract
A heat exchanger including an array of tubes (10) mounted between two fluid boxes (28, 46) via respective manifolds (16) and designed to have a fluid run through. The tubes (10) include at least two channels separated by at least one longitudinal partition (78) and are arranged in a single row, parallel to the two large surfaces of the exchanger, such that the fluid circulation occurs in at least two layers parallel to the large surfaces of the exchanger and each formed by part of the tube channels. At least one of the fluid boxes (28, 46) includes an internal longitudinal partition (48, 68) 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.
