Abstract
A heat exchanger for heat extraction of a refrigerating fluid such as CO2, comprising at least one collecting box defined by a solid body (41) with a thick wall capable of resisting the high pressure of said fluid, and communicating with a row of flat tubes (44). In order to limit bulkiness in the width of the heat exchanger, only one part of the length of the cross section of the tubes is located opposite the inner volume of said body, whereby tightness of the fluidic communication between the tubes and the inner volume is obtained by means of a cradle (50) in the form of a shaped strip receiving the body and brazed thereto on the periphery of the tubes. The heat exchanger can be used to air condition passenger compartments in vehicles.
