Abstract

The invention relates to an evaporator for exchanging heat between an airflow and a coolant, comprising an array consisting of a single row of flat tubes (1) stacked in alternation with wavy dividers (2). Said dividers keep the tubes a distance (d) away from each other, their waves defining the channels for the airflow in the direction of the breadth of the tubes (1). Each tube (1) has a U-shape, with the ends of each of the two limbs communicating with two chambers of a single fluid container (31) respectively, in such a way as to define a path for the coolant in an even number of segments in the evaporator. According to the invention, the dimension (l) of the evaporator in said direction is between 20 and 48 mm and the distance (d) is between 4.0 and 7.6 mm.
