Abstract

L'échangeur (WGC2;WGC3) comprend au moins deux refroidisseurs attenants (30,40;30',40'), comportant chacun un faisceau (34) de tubes multicanaux allongés parcourus par le gaz réfrigérant, réunis par des boîtes collectrices d'extrémité (36,38) reliées à un circuit de gaz réfrigérant de l'équipement de climatisation. Un carter (50) enferme le faisceau de tubes et forme un espace intérieur avec une entrée et une sortie de liquide caloporteur pour permettre à celui-ci de circuler entre les tubes du faisceau. Les carters de deux refroidisseurs attenants (30,40; 30',40') possèdent une paroi commune (52) comportant au moins un orifice (60) de mise en communication des deux volumes intérieurs. Il est ainsi possible de réaliser un refroidisseur de gaz compact intégrant dans un même bloc deux étages échangeurs eau/gaz (WGC2,WGC3), ainsi qu'éventuellement un échangeur interne gaz/gaz du circuit de climatisation.

Figure imgaf001
The exchanger (WGC2; WGC3) comprises at least two adjacent coolers (30, 40, 30 ', 40'), each having a bundle (34) of elongate multi-channel tubes traversed by the refrigerant gas, joined by collector boxes. end (36,38) connected to a refrigerant gas circuit of the air conditioning equipment. A housing (50) encloses the tube bundle and forms an interior space with an inlet and a coolant outlet to allow it to flow between the tubes of the bundle. The casings of two adjacent coolers (30,40; 30 ', 40') have a common wall (52) having at least one orifice (60) for placing the two inner volumes in communication. It is thus possible to produce a compact gas cooler incorporating in the same block two water / gas exchange stages (WGC2, WGC3), as well as possibly an internal gas / gas exchanger of the air conditioning circuit.
