Embodiment Construction

[0087] The drawings and their description illustrate the invention in detail and in terms of specific ways of carrying out the invention. Of course, they can better define the invention.

[0088] exist figure 1Among them, an air conditioning device for a vehicle, in particular a motor vehicle, comprises a closed circuit 1 in which a refrigerant fluid FR flows. In the exemplary embodiment shown, the circuit 1 comprises a compressor 2 , a condenser 3 or gas cooler, an expansion member 4 and at least one heat exchanger 5 substantially sequentially in the flow direction S1 of the refrigerant fluid FR.

[0089] The illustrated example of a minimal architecture for Loop 1 is given by indication and does not limit the scope of the invention in terms of potentially different architectures for Loop 1 .

[0090] The heat exchanger 5 is used, for example, to cool the air flow FA passing through it, as figure 2 shown. This air flow FA is used in particular to heat treat the air insid...

Abstract

The invention relates to a distribution device (18) for distributing refrigerant fluid (FR) in a collection tank (7) of a heat exchanger (5). The distribution device (18) comprises at least a first conduit (14) extending along a longitudinal axis (A1) defining a longitudinal direction in which the distribution device (18) extends. Said first duct (14) comprises at its first longitudinal end (15) an inlet opening (10) for refrigerant fluid (FR) entering the first duct (14) and at its second longitudinal end (16) is closed. Said first conduit (14) comprises, along at least a part of its longitudinal axis (A1), a plurality of discharge orifices (17) for removing refrigerant fluid (FR) from the first conduit (14). At least two orifices (17) adjacent along the longitudinal axis (A1) of said first duct (14) are inclined towards the second end (16) of the first duct (14), they are directed towards the first duct (14) ) inner openings (17a) are closer to its first end (15) than their openings (17b) towards the exterior of the first duct (14).

Description

technical field [0001] The field of the invention is that of heat exchangers fitted to air-conditioning devices for vehicles, in particular motor vehicles. The invention relates more particularly to the manner in which the refrigerant fluid is distributed within a collecting tank / tank equipped with such a heat exchanger. Background technique [0002] Vehicles are often equipped with air conditioning units for thermally treating the air present in or fed into the interior of the vehicle. Such a device comprises a closed circuit in which a refrigerant fluid flows. Continuously, and in the direction in which the refrigerant fluid flows through it, the circuit basically comprises a compressor, a condenser, an expansion valve and at least one heat exchanger. [0003] A heat exchanger typically consists of a bundle of tubes between a collection tank and a return tank for the return refrigerant fluid. Refrigerant fluid enters through an inlet opening in the collection tank, flow...
