Abstract

The collector (1) has a housing comprising connection openings for supplying or discharging a refrigerant and provided with a sealing plate (2) at its end side (6). The sealing plate is adhered with the housing and permanently secured with the housing by a mechanical connection. Another sealing plate is soldered or welded with the housing, and is detachably connected with the housing. The housing is closed by the sealing plates, which are arranged at the end sides of the housing. An independent claim is also included for a method for manufacturing a condenser.

Description

The The invention relates to a collector, in particular for a Refrigerant circuit of an air conditioning system of a motor vehicle, according to the preamble of claim 1.

such Collectors are known in the art and consist of a housing, which has an inlet opening and a drain port with a header of a condenser communicating, that means with the refrigerant circuit the air conditioning is connected. The collector takes a dryer / filter element on, for example, as a one-piece or multi-part plastic injection molded part is trained. Located inside the dryer / filter element a dryer granules which moisture the refrigerant (Water) withdraws. The collector is through two closure plates at both ends of the collector housing refrigerant tight completed to the environment.

Further It is known from the prior art that the closure plates detachable or unsolvable with the housing associated with the collector. In the latter case, the closure plates through a soldering or welding process with the housing connected to the collector. As the dryer granules of the dryer / filter element It must not be exposed to high temperatures during the soldering or welding process located near the closure plate. Therefore, that will Dryer element after the soldering or welding process used in the collector.

In the DE 103 06 192 A1 a closure plate is soldered to the housing of the collector simultaneously with the soldering of the tube / rib block of a capacitor. Subsequently, the dryer / filter element is inserted into the collector and finally soldered the second closure plate with the housing of the collector, welded or glued.

One Soldering or welding process is costly and due to the high temperatures to which the collector and the dryer / filter element are exposed There is a risk that the dryer / filter element destroyed becomes. In a sole bonding of the closure plate with the Housing of the collector there is a risk that the pressure tightness is no longer guaranteed.

It Object of the invention to produce a collector, in which with simple and inexpensive means an insoluble pressure-tight connection between the housing of the collector and a closure plate is produced without this Collector, especially the dryer / filter element high temperatures is suspended.

These Task is solved by a collector with the features of claim 1. Advantageous embodiments are the subject of Dependent claims.

According to one The basic idea of the invention is a collector, in particular for a refrigerant circuit of an air conditioner of a motor vehicle, with a housing with two connection openings designed to supply or discharge a refrigerant, wherein the housing at least on one end side with a first closure plate is provided, wherein the first closure plate glued to the housing of the collector and by another mechanical Connection with the collector is permanently secured.

The further mechanical connection is a form-fitting or a non-positive or a cohesive Connection or a combination of the latter types of connection.

By This arrangement becomes an insoluble one that is easy and quick to make Connection between the housing of the collector and a Closure plate achieved without the collector, especially the Dryer / filter element is exposed to high temperatures.

In An advantageous embodiment of the invention is a closure plate soldered to the housing of the collector undetachable or provided with a releasable closure plate and the other sealing plate glued to the housing of the collector and unsolvable by another mechanical connection secured with the housing of the collector.

In In a particularly preferred embodiment, this is mechanical Connection a screw connection.

In Another embodiment of the invention is the collector communicating with a manifold of a condenser and / or connected to a condenser communicating.

• – Einpressen der Verschlussplatte in das Gehäuse des Sammlers
• – Unlösbare Sicherung des Gehäuses des Sammlers mit der zweiten Verschlussplatte durch eine weitere mechanische Verbindung

In a further embodiment of the invention, a method for producing a capacitor is advantageous, which includes the following steps:

• - Soldering or welding a tube / rib block with the headers and the collector and soldering or welding a closure plate with the collector
• - Positioning of the dryer / filter element in the collector
• - Applying an adhesive to the edge of the second closure plate and / or on the housing of the collector
• - Pressing the closure plate into the housing of the collector
• - Undetachable securing of the housing of the collector with the second closure plate by another mechanical connection

alternative it is possible in a further process, both closure plates of the collector to be bonded to the housing of the collector and with another mechanical connection insoluble with each other connect to.

It it is understood that the above and the following yet to be explained features not only in each case specified combination, but also in other combinations or can be used in isolation, without the scope of the present To leave invention.

Further important features of the present invention will become apparent from the following detailed description in conjunction with the claims and the drawings.

following Be preferred embodiments of an inventive Described collector and closer reference to the accompanying drawings explained.

It demonstrate:

1 a portion of a condenser for a refrigerant condenser according to the present invention;

2 a section of a collector of another embodiment of the present invention;

3 a section of a collector of another embodiment of the present invention;

4 a section of a collector of another embodiment of the present invention;

1 shows a housing section 8th a collector 1 for a refrigerant condenser, not shown, according to the present invention. Such a collector consists of a tube, preferably made of aluminum, which has a lower open tube end 5 having. The pipe end 5 is connected to a pipe section, not shown, preferably extruded, which completes the collector. The latter pipe section is connected in a known manner with a manifold of a capacitor, not shown, mechanically and communicatively. Thus, the refrigerant has the lower pipe end 5 Access to the interior of the collector 1 ,

Further, the housing of the collector has an upper end side 6 on which by a closure plate 2 is closed. The closure plate 2 is with the housing of the collector 1 at the interface 4 bonded.

In addition, the housing is rolled up near the closure plate 3 , By this further mechanical connection, the pressure tightness is guaranteed.

2 shows a housing section 8th a collector 1 a further embodiment of the present invention. In contrast to the embodiment according to 1 will be the case of the collector 1 pressed in near the closure plate 3 , This can be done partially in the form of tabs or over the entire circumference of the collector. The glue applied to the bonding surface 4 between housing and closing plate ensures the appropriate tightness of the collector.

3 shows a housing section 8th a collector 1 a further embodiment of the present invention. In contrast to the embodiment according to 1 becomes the collector 1 near the lock plate with a circlip 3 Mistake. The housing must be equipped with a circlip 3 receiving groove 7 be executed. This will make the closure plate 2 against the circlip 3 pressed. The glue applied to the bonding surface 4 between housing and closing plate ensures the appropriate tightness of the collector.

4 shows a housing section 8th a collector 1 a further embodiment of the present invention. In contrast to the embodiment according to 1 becomes the collector 1 and the closure plate 2 partially with a short thread 3 Mistake. The housing is designed here with an internal thread and the closure plate with a corresponding external thread. This results in an enlarged adhesive surface 4 between housing and closure plate 2 , The closure plate may be due to the thread 3 no longer be pushed out. The glue applied to the bonding surface 4 between housing and closing plate ensures the appropriate tightness of the collector.
