Abstract

The present invention relates to a heat exchanger for changing the state of a fluid, for example an evaporator (1) for the fluid used in an air conditioning apparatus, the heat exchanger comprising tubular circuits (4) extending through fins (5), a distributor assembly for the fluid in a first state, connecting a fluid delivery tube to the input ends (6) of the said tubular circuits (4), and a collector assembly for collecting the fluid in a second state, the collector assembly being disposed so as to connect the outlet ends (8) of the tubular circuits (4) to a suction tube (10) and comprising a cylindrical part (11) arranged to form a coaxial extension of the suction tube (10) and being of larger radius than the suction tube. The invention is especially applicable to automotive vehicles.
