Title:
REFRIGERANT CONDENSER ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2012/098264
Kind Code:
A3
Abstract:
The invention relates to a refrigerant condenser assembly for a motor vehicle air conditioning system, comprising cooling pipes for conducting a refrigerant, two manifolds (5) for fluidically connecting the cooling pipes, a collecting reservoir (6) having an upper cover wall (21) and a lower floor wall (22) and a side wall (20) and having an inlet opening (18) for introducing the refrigerant into the collecting reservoir (6) and an outlet opening (19) for discharging the refrigerant from the collecting reservoir (6), wherein there is a first flow path of the refrigerant through a storage chamber (28) and therefore the collecting reservoir (6) is fluidically connected to the manifold (5) and/or the cooling pipes (2) by means of the inlet and outlet openings (18, 19), wherein the collecting reservoir (6) preferably comprises an outlet chamber (24) and a riser pipe (25), and wherein the outlet opening (19) opens into the outlet chamber (24), and wherein the outlet chamber (24) is connected to the riser pipe (25) and therefore the first flow path leads through the riser pipe (25) to the outlet opening (19), wherein the cooling pipes (2) preferably have a superheat region (11) for cooling the vaporous refrigerant, a condensing region (12) for condensing the refrigerant, and a supercooling region (13) for cooling the liquid refrigerant, wherein the supercooling region (13) is formed above the superheat region (11) and above the condensing region (12). In said refrigerant condenser assembly, it should be possible for a large amount of gas fractions, in particular at low filling levels and/or high mass flow rates, to be deposited in the collecting reservoir (6). Said aim is achieved in that a second flow path from the inlet opening (18) to the outlet opening (19) is formed by a bypass (14), in particular at the collecting reservoir (6), the second flow path bypassing the storage chamber (28) and preferably bypassing the riser pipe (25) at least partially, preferably completely.
