DESCRIPTION:
BRIEF SUMMARY
The invention relates to a condenser for a vehicle air-conditioning system, which condenser contains a pipe-rib block provided on both sides with collecting pipes which are divided by means of partitions in such a way that the pipe-rib block forms an upper condensing portion for gaseous refrigerant and a lower supercooling portion for liquid refrigerant, between which, paralled to a collecting pipe, there is disposed a collector.
In a known condenser of the type stated in the introduction (EP 0 480 330 A2), the collector, which serves as a type of intermediate store for liquid and gaseous refrigerant, is connected up to a connecting line between the condensing portion and the supercooling portion.
The object of the invention is to configure a condesner of the type stated in the introduction such that a relatively large design scope exists with regard to the configuration of the condensing portion and, in particular, of the supercooling portion.
This object is achieved, in a condenser of the generic type, by virtue of the features of claim 1.
The arrangement of the collector, which is connected by respectively dedicated connecting openings to the condensing portion and the supercooling portion, allows for greater design scope. In particular, it is possible to design the supercooling portion within the condenser such that the liquid coolant is fed to the supercooling section in the region of the lower end of the condenser, so that the liquid coolant, en route to an outlet socket, flows through the condenser from the bottom upward with a plurality of counter-running motions. The design of the collecting pipe having the parallel collector as a double pipe, in whose wall separating the two pipe chambers the connecting openings are placed, produces an extremely compact construction containing no junctions or connecting points which have to be outwardly sealed.
In a first embodiment, it is envisaged that the double pipe is joined together from at least two sheet-metal profiles.
In another embodiment of the invention, it is envisaged that the double pipe is composed of sheet-metal profiles and an extruded connecting profile. In both embodiments, a pre-assembly is initially carried out and then the individual elements are soldered together in a furnace.
In a further embodiment of the invention, it is envisaged that the double pipe is an extruded twin-chamber pipe.
In a further design of the invention, it is envisaged that the pipe chamber which serves as a collector is arranged offset relative to the plane of the pipe-rib block. This offset arrangement can give rise to considerable installation advantages, especially where the condenser is disposed between a fan guard and a radiator for the vehicle engine liquid in the engine compartment, in which there is usually only a small amount of construction space available.
Further features and advantages of the invention derive from the following description of the embodiment represented in the drawing, in which:
FIG. 1 shows a vertical section (along the line I--I of FIG. 2) through a condenser according to the invention,
FIG. 2 shows a top view of the condenser of FIG. 1,
FIG. 3 shows a top view of a modified embodiment of a condenser according to the invention, exhibiting its position, in which it is installed in a motor vehicle, relative to further elements,
FIGS. 4 and 5 show modified embodiments for a double pipe which is composed of sheet-metal profiles and serves as collecting pipe and collector,
FIGS. 6 and 7 show projections of double pipes which serve as collecting pipe and collector and are manufactured as extruded pipes,
FIGS. 8 and 9 show top views of the double pipes serving as collecting pipe and as collector, respectively comprising a connecting profile and sheet-metal profiles fastened thereto.
FIG. 10 shows a vertical part-section through the lower region of a modified embodiment of a condenser with integrated collector, and
FIG. 11 shows a cross section through collecting pipe and collector in the region of a connecting opening.
