Description

The The invention relates to an arrangement for fixing a first heat exchanger at a second heat exchanger according to the Preamble of claim 1.

The mutual attachment of heat exchangers is in so-called cooling modules, which are usually in the front engine compartment of a motor vehicle are known. Such a cooling module comprises, for example, a coolant radiator, a capacitor and / or a charge air cooler which to connect with each other to form an assembly.

Around Such a connection between the individual above Provide heat exchangers are in the state of Technique various attachment concepts known.

One first fastening concept provides a heat exchanger to be fastened at another, carrying heat exchanger with Help to attach holders or half shells, taking the connection z. B. by clip connections on the collecting container to be fastened Heat exchanger or by screw connections is reached. The holders are either fixed to the collection containers connected to the heat exchanger to be fastened or with half-shells or holders attached to the collecting container clipped the heat exchanger to be attached become. These half-shells or holders are in turn at one Collecting container of the bearing heat exchanger fastened by means of clip or screw connections.

One second attachment concept, on the other hand, the to be fastened Heat exchanger by means of holders or holders to be fastened in the storage tanks of the bearing Heat exchanger are integrated.

In DE 103 48 701 A1 For example, an arrangement for fixing a first heat exchanger to a second heat exchanger is described, wherein the first heat exchanger is arranged parallel to the second heat exchanger. The first heat exchanger has a heat exchanger block as well as mutually arranged manifolds with integrated collector. The second heat exchanger has a tube / rib block with plastic boxes mounted on both sides. In order to realize the connection between the first and second heat exchanger, the first heat exchanger is fastened by holding means, which are molded onto the collecting tanks of the second heat exchanger.

In DE 10 2005 40 607 A1 an arrangement for fixing a first heat exchanger to a second heat exchanger is described, wherein the connection between the two heat exchangers is achieved in that the first heat exchanger on the one hand by holding means, which are integrally formed with the first header of the second heat exchanger, and on the other Heat exchanger soldered holder are attached to the second heat exchanger.

at the above-described connections between the heat exchangers However, it is disadvantageous that an approximately equal block size of the respective Heat exchanger blocks in the horizontal is required to avoid failure of the holder. The assembly of heat exchanger blocks with different Block size is according to the above and not known from the prior art connection configurations.

According to one further known from the prior art third attachment concept is the heat exchanger to be fastened to a support frame attached. This support frame is then in turn on a supporting Heat exchanger attached.

at However, such a configuration is disadvantageous in that the additional bracing for the assembly the heat exchanger blocks with different Block dimensions more material must be used. Furthermore created by the support structure by means of holding frame a block the airflow.

Therefore It is the object of the present invention to provide an arrangement for Fixing a first heat exchanger to a second heat exchanger to create which different Dimensions, in particular in the horizontal, have.
