Description

[0001] The invention relates to a holding element for at least one heat exchanger for arrangement in a vehicle.

[0002] From DE 100 61 561 A1, a modular support for a heat exchanger of a motor vehicle engine is known. The modular support consists of a support frame to which a coolant air cooler and an air conditioning condenser are attached. The support frame comprises a lower part with a cross member as its base and two side parts projecting perpendicularly from it, the lower part having upwardly open compartments for inserting the coolant air cooler and the air conditioning condenser. These upwardly open compartments are closed off by an upper support, which connects the free ends of the side parts to each other to form the support frame and secures the inserted heat exchanger in its position.

[0003] The invention is based on the objective of providing a novel holding element for at least one heat exchanger for arrangement in a vehicle.

[0004] The problem is solved according to the invention by a holding element which has the features specified in claim 1.

[0005] Advantageous embodiments of the invention are the subject of the dependent claims.

[0006] According to the invention, a holding element for at least one heat exchanger for arrangement in a vehicle comprises - a U-shaped support frame element, along whose parallel legs a plurality of fastening points are provided, wherein the fastening points are arranged and / or formed in pairs at the same height on the inside of the legs opposite each other, and - another support frame element with additional attachment points for the form-fitting and / or force-fit attachment of the further support frame element to the two legs of the U-shaped support frame element.

[0007] Such a retaining element can be adapted to different sizes of heat exchangers by means of the multiple attachment points on the two support frame elements, which are designed as identical parts. In particular, the additional support frame element can be attached to the legs of the support frame element at different heights, depending on the size of the respective heat exchanger, using a form-fit and / or force-fit connection.

[0008] Exemplary embodiments of the invention are explained in more detail below with reference to drawings.

[0009] This shows: Fig. 1. Schematic perspective view of a mounting element for the arrangement of a heat exchanger in a vehicle, Fig. 2 schematically a perspective view of an exploded view of the retaining element, Fig. 3 schematically a view of the holding element with heat exchanger, Fig. 4 schematically shows a section of a possible design of the retaining element, Fig. 5 schematically shows a section of another possible design of the retaining element and Fig. 6 schematically shows an alternative embodiment of the retaining element.

[0010] Corresponding parts are marked with the same reference symbols in all figures.

[0011] Fig. Figure 1 shows a perspective view of a holding element 1 for a Fig. 3. Heat exchangers 2 shown as examples and in a highly simplified manner for arrangement in a vehicle not shown in detail, in particular for arrangement in an engine compartment of the vehicle.

[0012] In Fig. Figure 2 shows a perspective view of an exploded view of the multi-part retaining element 1.

[0013] The retaining element 1 is essentially designed in two parts and comprises a U-shaped support frame element T1 and a further support frame element T2, wherein the retaining element 1 is designed to hold at least one heat exchanger 2.

[0014] The two support frame elements T1, T2 are designed as identical parts and can therefore be used largely unchanged for different sized heat exchangers 2, whereby the further support frame element T2 can be positioned on the support frame element T1 according to the size of the heat exchanger 2 to be held.

[0015] The support frame element T1 is U-shaped and has two parallel legs S1, S2, which are of equal length and connected by a connecting web V, so that the heat exchanger 2 is enclosed on three sides by the support frame element T1. The distance between the two legs S1, S2 corresponds in particular to a width of the heat exchanger 2 and is fixed.

[0016] The further load-bearing element T2 is, as in a Fig. 2 shown embodiment is web-shaped and attached to the two legs S1, S2 of the supporting frame element T1 in a form-fit and / or force-fit manner.

[0017] For the form-fit and / or force-fit fastening of the two support frame elements T1, T2 depending on the size of the heat exchanger 2, these, in particular in the Fig. 4 and Fig. Five exemplary, corresponding forms F1, F2 are shown.

[0018] Several fastening points B1, in particular projections F1, are provided in pairs opposite each other along the inner sides of both legs S1, S2 of the support frame element T1. These mounting points are arranged and / or specifically formed on the two legs S1, S2. The further support frame element T2 has further projections F2 corresponding to these projections F1 as additional fastening points B2, so that the further support frame element T2 can be attached to the support frame element T1 in a form-fit and force-fit manner by means of its further projections F2 corresponding to the projections F1.

[0019] In an alternative embodiment of the connection between the two support frame elements T1 and T2, the fastening points B1 of support frame element T1 are designed as a continuous recess. The further support frame element T2, which according to Fig. 2 is designed in a web-like form, in particular has a recess on both end faces as further attachment points B2, wherein the two recesses in particular have the form of a blind hole.

[0020] For example, the recesses in the legs S1, S2 of the support frame element T1 and on the end faces of the further support frame element T1, T2 each have an internal thread. Thus, the two support frame elements T1, T2 can be screwed together, with each screw being inserted through the respective recess in legs S1, S2 and into the respective recess in the further support frame element T2.

[0021] Alternatively, only the recesses of support frame element T1 or the further support frame element T2 can be provided with an internal thread, so that the respective screw is only screwed into one of the support frame elements T1, T2, and the two support frame elements T1, T2 are thus still fastened to each other. In this case, the respective screw either protrudes through the recess of the respective leg S1, S2 and is screwed into the recess of the further support frame element T2, or the respective screw is screwed through the recess in the respective leg S1, S2 and inserted into the recess of the further support frame element T2 without being screwed into it.

[0022] Alternatively, only one recess can be formed as a fastening point B1 on the respective leg S1, S2, and extend as an elongated hole over a predetermined area of ​​the respective leg S1, S2. To create a positive and force-fit connection between the two support frame elements T1, T2, the respective recess of the further support frame element T2 then has an internal thread, so that the respective screw is passed through the elongated recess in the respective leg S1, S2 of the support frame element T1 and screwed into the recess of the further support frame element T2.

[0023] In particular, the heat exchangers 2, which can be received by means of the retaining element 1, are identical in width, while the height of the heat exchangers 2 can vary in such a way that the further support frame element T2 can be positively and / or force-fitted to the fastening points B1 of the support frame element T1 when the heat exchanger 2 is received. For this purpose, a plurality of fastening points B1 are arranged and / or formed along a predetermined area of ​​the respective leg S1, S2.

[0024] Additionally or alternatively, the positive and force-fit connection of the two support frame elements T1, T2 can be designed using clips and / or locking lugs and / or other suitable locking elements as exemplary forms F1, F2 for a locking connection.

[0025] It may also be provided that the fastening points B1 of the support frame element T1, designed as forms F1, and / or the further fastening points B2 of the further support element T2, designed as further forms F2, are arranged in a predetermined area of ​​the respective support frame element T1, T2 in a displaceable manner, for example telescopically displaceable.

[0026] Fig. Figure 3 shows a view of the assembled two-part retaining element 1 with the heat exchanger 2 incorporated.

[0027] Fig. Figure 4 shows a section of a possible embodiment of the two-part retaining element 1. The respective attachment point B1 of the two legs S1, S2 is, for example, designed as a wedge-shaped projection F1, whereas the further attachment point B2 is designed as a further projection F2, which corresponds to the shape of projection F1 of the respective leg S1, S2. For example, the further projection F2, in particular a form element, is slidably arranged on the web-shaped further support frame element T2. If the heat exchanger 2 is arranged in the retaining element 1, the form element as a further projection F2 is held in its position, for example by means of the heat exchanger 2, so that the further support frame element T2 is positively and force-fitted to the respective leg S1, S2 of the support frame element T1.

[0028] The further shape F2 can also be elastically deformable as a further attachment point B2 up to a predetermined dimension, so that when the retaining element 1 is mounted, the further shape F2 is initially pushed away from the leg S1, S2 of the support element T1 and, due to its resulting preload, locks into position in the shape F1 of the respective leg S1, S2 when the further support frame element T2 with the further shape F2 is positioned accordingly to the shape F1.

[0029] If the heat exchanger 2 has a lower height, the additional support frame element T2 is positioned in the direction of the connecting web V until a projection F1 corresponding to the height of the heat exchanger 2 is reached, into which the additional projection F2 of the additional support frame element T2 projects and the additional support frame element T2 is thus positively and force-fit attached to the support frame element T1.

[0030] In a Fig. In the further possible embodiment of the retaining element 1 shown in Figure 5, the further support frame element T2 is also U-shaped, with the legs S3 of the further support frame element T2 being shorter compared to the legs S1, S2 of the U-shaped support frame element T1.

[0031] In particular, it shows Fig. 5 an enlarged section of a connection area between the U-shaped support frame element T1 and the U-shaped further support frame element T2.

[0032] The two support frame elements T1, T2 are designed in such a way as to allow the legs S3 of the further support frame element T2 to be inserted into the legs S1, S2 of the support frame element T1 by a predefinable dimension in order to adapt the holding element 1 to the size of the heat exchanger 2 to be accommodated.

[0033] Alternatively, the legs S1, S2 of the support frame element T1 can be inserted into the legs S3 of the further support frame element T2 by a predefinable dimension in order to adapt the holding element 1 to the size of the heat exchanger 2 to be accommodated.

[0034] In particular, this form of the further support frame element T2 is chosen when the retaining element 1 is reduced in size relative to the heat exchanger 2 by shifting or inserting the legs S3 of the further support frame element T2, so that the required installation space for arranging the retaining element 1 with the heat exchanger 2 in a vehicle's engine compartment can also be reduced. The legs S1, S2 of the support frame element T1 therefore do not protrude.

[0035] For example, a connection between the two support frame elements T1, T2 can be made by means of a tongue and groove connection, so that the further support frame element T2 is arranged slidably, in particular slidably, on the support frame element T1.

[0036] Fig. Figure 6 shows an alternative embodiment of the retaining element 1, wherein the retaining element 1 in this embodiment is designed in such a way, particularly with regard to heat exchangers 2 to be accommodated, that heat exchangers 2 can be accommodated whose height is essentially the same, but whose width varies, wherein for this purpose the further support frame element T2 can be positioned and attached to the support frame element T1 on the two legs S1, S2, in particular by means of the attachment points B1, B2, according to a width of a heat exchanger 2.
