Definitions
- Coolant collecting box comprising at least one angular positioning device of a conduit
- the field of the present invention is that of the heat exchangers equipping the air conditioning installations for a vehicle, in particular an automobile.
- the invention relates more specifically to the distribution of a refrigerant fluid inside a manifold that includes such a heat exchanger.
- a vehicle is commonly equipped with an air conditioning unit for heat treating the air present or sent into the passenger compartment of the vehicle.
- Such an installation comprises a closed circuit inside which circulates a refrigerant fluid. Successively following the direction of circulation of the refrigerant fluid through it, the circuit essentially comprises a compressor, a condenser, a pressure reducer and at least one heat exchanger.
- the heat exchanger commonly comprises a bundle of tubes interposed between a header and a coolant return box. The refrigerant is admitted through an inlet mouth inside a manifold, flows along successive paths in the tubes of the bundle between the manifold and a return box, and is discharged out of the exchanger thermal through an outlet mouth.
- the heat exchanger is for example an evaporator providing a heat exchange between the refrigerant and a flow of air therethrough.
- the refrigerant circulates inside the tubes of the bundle and the air flow circulates along the bundle tubes for cooling.
- a problem lies in the fact that the refrigerant fluid is in the two-phase liquid / gas state when it is admitted inside the heat exchanger. Due to the difference between the physical properties between the liquid and the gas, the coolant tends to separate between its liquid phase and its gas phase. This results in a heterogeneity of the supply of the tubes of the beam with respect to the different phases of the refrigerant fluid, according to their position relative to the inlet mouth of the refrigerant fluid inside the manifold. More particularly, the tubes of the beam located closest to the inlet mouth 5 are mainly supplied with liquid and conversely the tubes of the beam farthest from the inlet mouth are mainly supplied with gas.
- This phenomenon generates a heterogeneity of the temperature of the air flow that has passed through the heat exchanger during operation. This heterogeneity complicates the thermal management of the apparatus that receives the heat exchanger and ultimately involves i o temperature differences between two areas of the cabin, while the same airflow temperature is required.
