ABSTRACT:
An evaporator consisting of stacked pockets wherein the refrigerating fluid is injected into an upstream connecting duct formed by a sub-assembly of the pockets by a longitudinal tubing which passes through an end face of the evaporator, distant from the upstream connecting duct, and at least another connecting duct formed by other pockets. According to the invention, the tubing is offset with respect to the centers of the openings through which the pockets forming the other connecting duct communicate between them. This results in an improvement in the heat exchange efficiency. The invention is applicable to the air conditioning of the passenger space of automobile vehicles.
