A collection box with an integrated reservoir for a heat exchanger, has a cylindrical tubular wall and a separation wall, disposed inside the tubular wall to delimit a collection compartment and a reservoir compartment. The tubular wall is equipped with spaced holes to receive the ends of tubes of a bundle of tubes. The separation wall comprises a central core prolonged on either side by a first edge region and by a second edge region having profiles each designed and suitable to be applied and soldered against the inside of the tubular wall.

Collection box with an integrated reservoir for a heat exchanger, in particular for a refrigeration condenser

The invention concerns an air conditioning condenser for a motor vehicle passenger compartment comprising a reservoir mounted on a base. The reservoir is axially screwed in the base, itself soldered on a manifold box of the condenser, communicating therewith through ducts arranged in the base. The base further comprises a mounting pin for helping to fix the condenser on the support, and/or a linking duct for connecting the condenser to the rest of the refrigerating circuit.

Air conditioning condenser comprising a reservoir mounted on a base

A condenser for a refrigerating circuit, in particular an air conditioning installation for a motor vehicle, comprises two headers at respective ends of a bundle of tubes, together with a reservoir communicating with one of the headers. The reservoir and this header are integrated within a common casing having a tubular wall which is divided, by a longitudinal separating baffle, into a collecting chamber, constituting the header into which the tubes of the condenser are open, and a reservoir chamber which communicates with the collecting chamber through apertures formed in the longitudinal baffle. This baffle has a longitudinal edge engaged in a longitudinal slot in the casing wall, and another longitudinal edge which bears against the tubular wall, so that the various components can be secured together by brazing.
