Description

Radiator assembly for a motor vehicle

Technical Field

The present invention relates to a radiator assembly for a motor vehicle.

Background

The heat sink assembly generally comprises components via which heat exchange between the surroundings of the heat sink assembly and the fluid flowing through the respective components is ensured. As these components, condensers and heat exchangers (e.g., for air conditioning systems) are known, for example. In the condenser, a phase change of the fluid flowing through the components may occur with respect to the heat exchanger.

The heat exchanger may comprise a first and a second collecting tank and at least a plurality of tubes, which extend from the first collecting tank to the second collecting tank, for example along the y-axis, in each case, for conducting the fluid flowing through these components. The lines between the collecting tanks can be arranged at a distance from one another in the z-axis in such a way that they can be flowed through in the x-axis (for example, opposite the direction of travel of the motor vehicle) for a gaseous medium (for example, ambient air). Here, the heat exchange takes place between the fluid guided through the conduit and the medium flowing through the conduit along the x-axis.

In particular, such a radiator module has a fan shroud and is preferably arranged in the front region of the motor vehicle, wherein the heat exchanger is mounted in the direction of travel, for example, upstream of the drive unit of the motor vehicle and upstream of the fan shroud.

DE 102004058724 a1 discloses a radiator module (sometimes referred to as a cooling module) for a vehicle. The heat dissipation module includes a heat exchanger and a fan. The heat exchanger is fixed at the upper and lower frames.

DE 102014201991 a1 relates to a heat sink for a motor vehicle. The heat sink comprises at least two heat dissipating elements which are connected to one another via a plug connection. In order to assemble the heat dissipating elements, one of the heat dissipating elements is arranged on the floating bearing side and then swiveled about a swivel axis arranged on the floating bearing side toward the other heat dissipating element, so that the plug connection is locked on the fixed bearing side.

DE 202009011439U 1 discloses an assembly for fastening a first heat exchanger (W ä rme U bertrager, sometimes referred to as a heat exchanger) to a second heat exchanger. For the fixation of the heat exchangers to one another, slightly elongate profile elements are provided, at which each of the heat exchangers is fixed.

There is a continuing need to implement heat sink assemblies as simply and with less complexity as possible, wherein the assembly of the heat sink assembly should likewise be performed as simply as possible.

Disclosure of Invention

The object of the present invention is to at least partly solve the problems listed with reference to the prior art. In particular, the complexity of the heat sink assembly should be reduced, wherein preferably the assembly of the heat sink assembly should also be performed as simply as possible.

The features listed in the patent claims can be combined with one another in a technically meaningful manner and can be supplemented by explanatory facts according to the description and/or by details according to the drawings, wherein further embodiments of the invention are illustrated.

It proposes a radiator module for a motor vehicle. The radiator module comprises at least one first, second and third component, which are respectively embodied as one of a condenser and a heat exchanger. The first component has at least one first receptacle (Aufnahme, sometimes referred to as a receptacle) for fastening the second component to the first component, at least one second receptacle for fastening the third component to the first component, and at least one support element for fastening the first component to the motor vehicle. The second member is disposed between the third member and the first member.

In particular, a heat exchange between the surroundings of the heat sink assembly and the fluid flowing through the respective component can be achieved via each of the components. In particular, each of the components then has at least one inlet, one outlet and at least one flow channel for the respective fluid connecting the inlet and the outlet. In particular, each of the components can be flowed through by a gaseous medium, so that a heat exchange between the at least one flow channel for the respective fluid and the medium is possible. In particular, the components are arranged opposite one another in such a way that the gaseous medium flows through them in succession in the flow direction.

In particular, the third component is a condenser. In particular, the first and second components are correspondingly heat exchangers.

In particular, at least one support element for fixing the first component to the motor vehicle is provided. In particular, a plurality of support elements are provided, via which the first component is fixed to the motor vehicle. In particular, the radiator arrangement is arranged in a stationary manner in the motor vehicle only via the first component. In particular, a positionally fixed arrangement of the heat sink assembly is ensured only via the at least one supporting element.

The stationary arrangement means in particular that a geometrically fixed position, i.e. a defined positioning of the relevant component in the superordinate assembly or in the motor vehicle, is thus ensured. The fixed position means in particular that a movement of the relevant component relative to the superordinate assembly or the motor vehicle is not possible, i.e. neither a rotational nor a translational movement.

The proposed heat sink assembly comprises a combination of different functions to the first component. It is particularly known to provide a frame for fixing the radiator module to the motor vehicle. For this purpose, the frame usually has a receptacle for fastening the component to the frame and a support element for fastening the frame to the motor vehicle. At least these functions of the receptacle and the support element are then performed by the first component.

In particular, the heat sink assembly has at least one first covering element, via which at least the second component is joined in a positionally fixed manner to the first component.

In particular, the heat sink assembly has at least one second cover element, via which at least the second component is joined in a positionally fixed manner to the first component. The first and second cover elements are arranged spaced apart from each other.

In particular, the at least one cover element extends only along a side face of the radiator module, in particular along the y-axis, which preferably extends transversely to the longitudinal axis and the yaw axis of the motor vehicle.

Therefore, no annular frame is formed on the cover element in particular.

The at least one cover element is in particular only fixed to the radiator module and does not itself make possible a fixed fixing of the radiator module in position on the motor vehicle.

In particular, at least one cover element has a sealing element for fluid-sealing a gap existing between the first component and the second component with respect to the surroundings of the heat sink assembly.

The sealing element may in particular be formed by an elastically deformable membrane, by means of which at least partial sealing of the gap is achieved. In particular, the flow path for the gaseous medium can be limited in such a way that as far as possible the entire volume flow of the medium flowing through the first or second component is likewise guided through the respective other of the first and second component. As a result, in particular, a heat exchange as efficient as possible can be achieved at the component.

In particular, the heat sink assembly is arranged in a coordinate system with an x-axis, a y-axis and a z-axis, wherein these components extend in a y-z plane that is spanned by the y-axis and the z-axis.

In particular, the second component is arranged rotatably about the z-axis in one of the plurality of first receptacles during the assembly process, wherein the second component is arranged fixedly and non-displaceably (underroof) on the first component by means of the arrangement position of the at least one cover element.

In particular, the z axis runs parallel to the yaw axis of the motor vehicle, wherein the x axis runs parallel to the longitudinal axis of the motor vehicle.

The extension of the components is essentially predetermined by the position of the cross sections of the respective components provided for the heat exchange between the fluid and the medium, which cross sections extend in particular in the y-z plane and can be flowed through by the medium along the x axis.

In particular, all components are arranged substantially parallel to one another. In particular, the cross-sections of the individual components provided for the heat exchange are arranged substantially flush (sometimes referred to as aligned) with one another along the x-axis.

In particular, the second component can be arranged rotatably about the z axis in one of the plurality of first receptacles. The second component may be arranged at the first component at an angle and twisted towards the first component at the angle and about the z-axis after being arranged in the first receptacle. In particular, the second component is then fixed in a fixed position in at least four, preferably five, of the six possible degrees of freedom (three translational degrees of freedom and three rotational degrees of freedom).

The fifth and/or sixth degree of freedom of the second component is fixed by at least one covering element which connects the first component and the second component to one another.

In particular, the at least one cover element is fixed at least one of the first part and the second part only via the at least one stop and the at least one latching hook. In particular, the connection between the first part and the second part is established via at least one catch and at least one stop.

The embodiment of the opposite covering element applies in particular equally to the other covering element and preferably correspondingly to both covering elements.

In particular, at least the first and the second component extend in respective planes parallel to each other and transversely to the plane in the first cross section of the first component and in the second cross section of the second component, through which the gaseous medium for heat exchange can flow. The gap defined by these cross sections between the first component and the second component is sealed fluid-tightly against the surroundings of the heat sink assembly by at least one sealing element. The at least one sealing element is arranged at the first component.

In particular, all components are arranged substantially parallel to one another. In particular, the cross sections of the individual components provided for the heat exchange are arranged substantially flush with one another along the x axis and accordingly extend in the y-z plane.

The same applies here in particular for the above-described embodiments of the sealing element arranged at the covering element. In particular, the at least one sealing element at the at least one cover element can be used or provided for the fluidic sealing of the gap in addition to the at least one sealing element at the first component.

In particular, the first component has at least one third receptacle for fixing a fourth component to the first component, wherein the first component is arranged between the second component and the fourth component.

In particular, the fourth component is a fan shroud. In particular, the heat sink assembly comprises first the third component and then, in succession, the second component, the first component and the fourth component in the prescribed flow direction of the medium.

It proposes a method for assembling the described heat sink assembly. The method at least comprises the following steps:

a) providing a first component; then the

b) Arranging the second component at the first component and fixing the second component at the at least one first receptacle;

c) the third component is arranged at the assembly of at least the first and second components and is fixed at the at least one second receptacle.

In particular, at least one covering element is provided at least after step b), if possible after step c), and is arranged at the assembly of at least the first and second component (if possible additionally comprising a third component). At least the second component is connected to the first component in a fixed position via at least one cover element.

The fourth component may be arranged at the first component after each of steps a), b) and c).

In particular, steps a) to c) are performed in the listed order. Between steps a) and b) and c), further steps may be performed, such as the fixation of the fourth component at the first component. Between steps b) and c) or after step c), for example, at least one covering element can be fixed at the assembly of at least a first and a second component.

Accordingly, the concepts or components introduced accordingly are to be understood in such a way that they can be present at least once and in particular, but also several times.

Embodiments of the heat sink assembly may be particularly transposed to the method and vice versa.

For the sake of precaution, it is to be noted that the terms "first", "second", … … (used herein) are preferably used (merely) to distinguish a plurality of similar objects, dimensions, or processes, i.e. in particular the relation and/or the order of these objects, dimensions, or processes to each other is not mandatory to be given in advance.

The radiator module 1 includes a heat exchanger as a first block 3, a heat exchanger as a second block 4, a condenser as a third block 5, and a fan shroud as a fourth block 21. A frame 22 is provided for fixing the radiator modules 1 to one another and to the motor vehicle 2. For this purpose, the frame 22 and the

individual components

3,4,5 have

receptacles

6,7,20 for fastening the

The radiator module 1 comprises a first part 3, a second part 4 and a third part 5, which are respectively embodied as one of a condenser and a heat exchanger. The first component 3 (heat exchanger) has a plurality of first receptacles 6 for fastening the second component 4 (heat exchanger) to the first component 3, a plurality of second receptacles 7 for fastening the third component 5 (condenser) to the first component 3, and a plurality of support elements 8 for fastening the first component 3 to the motor vehicle 2. The second part 4 is arranged between the third part 5 and the first part 3.

The radiator module 1 is arranged in a stationary manner in the motor vehicle 2 only via the first component 3. The positionally fixed arrangement of the heat sink assembly 1 is ensured only via the supporting element 8.

The proposed heat sink assembly 1 comprises a combination of different functions to the first component 3. At least the function of the receiving means 6,7,20 and the support element 8 is then fulfilled by the first component 3.

The heat sink assembly 1 has a first cover element 9, via which the second component 4 is joined in a positionally fixed manner to the first component 3. The heat sink assembly 1 has a second cover element 10, via which the second component 4 is joined in a positionally fixed manner to the first component 3. The first 9 and the second 10 cover element are arranged spaced apart from each other.

The

cover elements

9,10 extend along the y-axis 14, respectively, only along the sides of the heat sink assembly 1. Thus, no annular frame 22 is formed on the

covering elements

9,10, see fig. 2.

The

cover elements

9,10 are only fixed at the radiator module 1 and do not themselves make possible a fixed fixing of the position of the radiator module 1 at the motor vehicle 2.

The heat sink assembly 1 is arranged in a coordinate system with an x-axis 13, a y-axis 14 and a z-axis 15, wherein the

components

3,4,5,21 extend in a y-z plane that is spanned by the y-axis 14 and the y-axis 15.

The extension of the

components

3,4,5,21 is approximately predetermined by the position of a

cross section

18,19 of the

respective component

3,4 provided for the heat exchange between the fluid and the medium, which cross section extends in the y-z plane and can be traversed by the medium along the x axis 13.

The fourth component 21 is a fan shroud. The heat sink assembly 1 comprises first the third component 5 and then, in turn, the second component 4, the first component 3 and the fourth component 21 along a defined flow direction of the medium, i.e. along the x-axis 13.

Fig. 8 shows, in a perspective view, a rotation of the second component 4 about the z-axis 15 during step b) of the method and after fig. 7 in time, the rotational axis 26 extending through the first receptacle 6. The second component 4 is fixed in position after twisting in five of the six possible degrees of freedom (three translational degrees of freedom and three rotational degrees of freedom), see also fig. 17.

Fig. 9 shows the assembly of the first component 3 and the second component 4 after step b) of the method and during the arrangement of the first covering element 9 in a perspective view. The first covering element 9 is transported along the z-axis 15.

The cover element 9 has a sealing element 11 for fluidically sealing a gap 12 present between the first component 3 and the second component 4 with respect to an ambient environment 25 of the heat sink assembly 1. The sealing element 11 is formed by an elastically deformable membrane, by means of which at least partial sealing of the gap 12 is achieved. The flow path for the gaseous medium can therefore be restricted in such a way that as much as possible of the entire volume flow of the medium flowing through the first component 3 or the second component 4 is likewise guided through the respective other of the first component 3 and the second component 4. As efficient a heat exchange as possible at the
