    15 20 25 It is previously known from DE 10 2007 006 928 A1 to mount two or more radiator devices on two rod-shaped support elements in order thereby to facilitate maintenance and service of the radiator devices. In this case, the brackets are mounted on the underside of the respective cooling device, these brackets being designed for engagement with respective rod-shaped support elements.
    OBJECT OF THE INVENTION The object of the present invention is to provide a radiator arrangement for a motor vehicle where the respective radiator device of the radiator arrangement is supported by a holding device in a new and advantageous manner.
    SUMMARY OF THE INVENTION According to the present invention, said object is achieved by means of a radiator arrangement having the features defined in claim 1.
    The radiator arrangement according to the invention comprises one or more radiator devices, the respective radiator device comprising: - an elongate first radiator tank, which forms a first end portion of the radiator device, - an elongate second radiator tank, which is arranged at a distance from the first radiator tank and forms a second end portion of the cooling device, and a cooling element, which is arranged between said cooling tanks and connected thereto for cooling a medium which passes via the cooling element between the cooling tanks.
    The cooler arrangement further comprises a holding device having three or more rod-shaped support elements for supporting said one or more cooler devices, these support elements being mutually parallel and arranged at a distance from each other.
    A first recess designed to receive a first of said support elements and a second recess designed to receive a second of said support elements are integrated in the first cooling tank of the respective cooling device. Furthermore, a third recess is designed to receive a third of said support elements integrated in the second cooling tank of the respective cooling device.
    Because the radiator devices are attached to the support elements via brackets which are designed as recesses integrated in the radiator tanks of the radiator devices, a stable construction is obtained, since it then becomes possible to dispense with the brackets in the form of separately designed components mounted on the radiator devices. from these. Since the cooling devices do not have to be provided with brackets in the form of separately designed components which are mounted on the cooling devices and project from them, the cooling devices can also be given a compact and space-saving design. The use of three or more rod-shaped support elements for supporting the cooling devices also means that the cooling devices can be anchored in the holding device in a stable and stable manner at at least three attachment points. According to an embodiment of the invention, a fourth recess is formed to receive a fourth of said support elements integrated in the second cooling tank of the respective cooling device. As a result, each cooling tank of the respective cooling device will be in engagement with at least two support elements, which provides a very stable and stable anchoring of the cooling devices in the holding device.
    According to another embodiment of the invention, the respective recesses have the shape of a through hole in the associated cooling tank or the shape of a laterally open channel which is designed as a depression in a longitudinal edge of the associated cooling tank facing away from the cooling element.
    According to another embodiment of the invention, the respective recesses of at least one of the cooling tanks of the respective cooling device have an elongated cross-sectional shape to allow uptake of shape changes of the cooling device caused by thermal expansion of the cooling element of the cooling device. In this way, temperature-related shape changes of the cooling device can be taken up in a simple and efficient manner. As an alternative, temperature-related deformations of the cooling device can be accommodated by means of bushings of elastic material which are arranged in the recesses and which extend around the mantle surface of the support elements received therein.
    Other advantageous features of the radiator arrangement according to the invention appear from the dependent claims and the description below. BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail below with the aid of exemplary embodiments, with reference to the accompanying drawings.
