The invention relates to a heat exchanger assembly for a vehicle according to the preamble of claim 1. The invention relates in particular to a vehicle comprising at least one such heat exchanger assembly.
Heat exchanger assemblies of the above-mentioned type are described, for example, in U.S. Pat. No. 10,274,267 B1, DE 10 2018 116 452 A1, and DE 10 2009 031 695 A1. They generally have a heat exchanger as well as a holder for fixing or holding, which is to be understood synonymously hereinafter, said heat exchanger to a structural component of a vehicle. The known holders are of relatively large construction and often completely enclose the entire circumferential edge of a heat exchanger, so that they are complex, in particular from a structural point of view, and thus have to be installed on the heat exchanger as well as on the structural component with much effort. The manufacture and installation of the known heat exchanger assemblies thus becomes relatively time- and cost-intensive, even though more cost-efficient solutions are desired for in order to increase the competitiveness.
It is thus the object of the invention to specify an improved or at least another embodiment for a heat exchanger assembly. A vehicle comprising at least one such heat exchanger assembly is to in particular also be provided.
In the case of the present invention, this object is solved in particular by means of the subject matters of the independent claims. Advantageous embodiments are subject matter of the dependent claims and of the description.
It is the basic idea of the invention to replace the holders, which are being used in the case of such a heat exchanger assembly for holding (or fixing) the heat exchanger with two separate, quasi modularly constructed lateral enclosures, the components of which, which will be referred to hereinafter as plug-in parts and fixing parts, are manufactured cost-efficiently, can be fixed relatively easily and quickly to a heat exchanger as well as to a structural component of a vehicle.
According to this, a heat exchanger assembly for a vehicle is provided, which has a heat exchanger, which is preferably produced in an all-aluminum construction, for example a coolant radiator or a condenser, and two separate lateral enclosures, which are in particular not directly cohesive and which hold (or fix) the heat exchanger. The lateral enclosures are arranged on sides of the heat exchanger, which are opposite to one another, in particular in a main direction referred to as X direction, in particular on short or long sides of the heat exchanger, which are aligned horizontally or vertically with respect to a ground, on which the vehicle is parked and which each enclose a section of a circumferential edge of the heat exchanger, and they are configured to jointly hold or to fix the heat exchanger assembly on a structural component of the vehicle. According to the invention, the lateral enclosures thereby each have a first, in particular separate plug-in part, which is fixed in a positive manner to the heat exchanger, a second, in particular separate plug-in part, which is fixed in a positive manner to the heat exchanger, as well as an in particular separate fixing part, which is arranged on the first plug-in part and/or on the second plug-in part, for fixing the respective lateral enclosure to the structural component. The lateral enclosures are thus in particular constructed in a quasi-modular manner. In the installed state of the heat exchanger assembly, the first plug-in parts and/or second plug-in parts are advantageously attached to the heat exchanger. It is furthermore essential that the first plug-in parts can be locked or are locked in a positive manner with the second plug-in parts. Compared to conventional solutions for holding heat exchangers, in the case of which in particular frames are used, which are of relatively large construction and which enclose the heat exchanger all around, the lateral enclosures proposed by the invention for holding the heat exchanger can be provided cost-efficiently in large quantities, are relatively compact, lightweight, and can be installed easily and quickly. This is attained in particular in that the plug-in parts and fixing parts, which are used to form the lateral enclosures, are structurally not very complex, and the plug-in parts are fixed to the heat exchanger by means of a positive connection, so that in particular no additional aids, such as, for example, adhesives or fastening screws, are required for installing the plug-in parts on the heat exchanger, wherein these positive connections can be designed in a detachable or non-detachable manner. This is further also attained in that the plug-in parts of a lateral enclosure can be locked or are locked easily and quickly with one another in a positive manner, for example by means of a clip connection (also locking connection), which forms a positive connection, which provides for the installation of the proposed heat exchanger assembly in particular manually by hand. Said positive connections can also be designed in a detachable or non-detachable manner. Plug-in parts and fixing parts are, for example, plastic parts or plastic composite material parts, whereby a cost-efficient and lightweight realization of the heat exchanger assembly is possible.
In terms of the invention, the expression “enclosing” can advantageously mean that the lateral enclosures encompass the heat exchanger, in particular engaging in a u-shaped manner. In terms of the invention, the term “holding” can advantageously be used like “fixing”. The heat exchanger, which is enclosed to be held by the lateral enclosures, is in particular held so that the heat exchanger fixes relative to the lateral enclosures, is thus immobile.
It is advantageous when the first plug-in parts and/or the second plug-in parts of the lateral enclosures are fixed in a positive manner to the heat exchanger by means of caulking with the heat exchanger. In particular at least one positive connection can or will be realized thereby, which is formed between and/or on the respective first plug-in part and/or the respective second plug-in part and the heat exchanger by means of caulking a first plug-in part and/or a second plug-in part of the lateral enclosures with the heat exchanger. The respective positive connection can thereby be characterized in that the respective first plug-in part, which is made of softer material with respect to the heat exchanger and/or the respective second plug-in part, which is made of softer material with respect to the heat exchanger, is cut and/or partially peeled and/or plastically deformed by means of the heat exchanger, which is made of harder material, whereby the respective first plug-in part and/or the respective second plug-in part wedges in a positive manner with the heat exchanger detachably or non-detachably as well as without play. A preferred positive connection for the first plug-in parts and/or the second plug-in parts with the heat exchanger is thus specified. This has the advantage that said first and second plug-in parts and the heat exchanger can be fixed to one another cost-efficiently, in particular without additional fastening means, such as, for example, adhesives or fastening screws. This positive connection can be designed in a detachable or non-detachable manner. This positive connection of said plug-in parts to the heat exchanger additionally allows for the use of different materials, for example a plastic-aluminum material pairing is conceivable, so that the heat exchanger assembly can be optimized in particular with regard to its weight as well as the manufacturing costs.
It is thereby advantageously easy to understand for the person of skill in the art that the expressions “made of softer material” and “made of harder material” refer to the respective material hardnesses of the used materials of the first and/or second plug-in parts or of the heat exchanger, respectively. The person of skill in the art can determine a respective material hardness, for example, by means of a generally known hardness testing method, for example according to Rockwell.
The invention advantageously understands the term “caulking” to be a joining process, in the case of which a positive connection is or will be realized by means of caulking two joining partners and which is characterized in that the one joining partner, which is made of softer material, for example said plug-in parts, is cut and/or partially peeled and/or plastically deformed by the joining partner, which is made of harder material, for example the heat exchanger, whereby the two joining partners are wedged together in a positive manner detachably or non-detachably as well as without play. It could thus also be defined that by means of caulking with the heat exchanger, the first plug-in parts and/or the second plug-in parts form a caulking or positive connection with said heat exchanger, within which the first plug-in parts and/or the second plug-in parts are wedged together in a positive manner releasably or non-releasably as well as without play with the heat exchanger, whereby the first plug-in parts and/or the second plug-in parts are fixed in a positive manner detachably or non-detachably and without play to the heat exchanger.
It is further advantageous when the lateral enclosures are each of U-shaped design. It can in particular also be provided that the first plug-in parts and/or the second plug-in parts of the lateral enclosures are each of L-shaped design. Preferred embodiments for the lateral enclosures or for the first plug-in parts and/or second plug-in parts of the lateral enclosures, respectively, are thus specified, by means of which in particular a rectangularly designed heat exchanger can be enclosed relatively well.
It can furthermore be provided that the first plug-in parts and/or the second plug-in parts of the lateral enclosures each have two legs, which are perpendicular to one another, each comprising a u-shaped leg cross section profile. It is advantageous when the two legs of a first plug-in part and/or the two legs of a second plug-in part form or limit a leg plug-in receptacle, which is limited by the respective u-shaped leg cross section profile, wherein the leg plug-in receptacles of the two legs of a first plug-in part and/or of a second plug-in part optionally limit or form a common, cohesive plug-in part plug-in receptacle of the first plug-in part and/or of the second plug-in part for immersion of the heat exchanger, so that the first plug-in parts and/or the second plug-in parts can be attached to the heat exchanger or are attached to the heat exchanger in the installed state of the heat exchanger assembly. A further preferred embodiment is thus specified for the first and second plug-in parts. The two legs of a first and/or second plug-in part each also form or limit a plug-in receptacle opening, which is predetermined by the respective u-shaped leg cross section profile and through which one can engage with the respective leg plug-in receptacle or the plug-in part plug-in receptacle, respectively.
It can advantageously be provided that in the installed state of the heat exchanger assembly, the first plug-in parts and/or the second plug-in parts are attached to the heat exchanger, wherein the heat exchanger is immersed into said plug-in part plug-in receptacles of the first plug-in parts and/or of the second plug-in parts and abuts with contact and in particular in a fluid-tight manner on the legs of the first plug-in parts and/or of the second plug-in parts. A sealing means can thereby advantageously be interconnected.
At least one first plug-in part and/or at least one second plug-in part of the lateral enclosures can in particular have support ribs for supporting the heat exchanger. The support ribs are thereby advantageously arranged on one leg of the two legs or on both legs of the respective first plug-in part and/or of the respective second plug-in part within the respective leg plug-in receptacle and are integrally connected to the respective leg. In each case starting at the respective leg, the support ribs advantageously protrude into the plug-in receptacle, so that the heat exchanger, which is completely inserted through, for example, a respective plug-in receptacle opening, can support on these support ribs with contact. Said support ribs are further advantageously arranged in pairs and so as to run parallel to one another within the leg plug-in receptacle on a leg wall, which is located opposite the respective plug-in receptacle opening, of the respective leg.
It can advantageously be provided that at least a first plug-in part and/or at least a second plug-in part of the lateral enclosures has positive ribs for forming a positive connection, which is or will be formed between and/or on the respective first plug-in part and/or the respective second plug-in part and the heat exchanger by means of caulking the respective first plug-in part and/or the respective second plug-in part with the heat exchanger. It can furthermore be provided that said positive ribs are arranged on at least one said leg of the two legs or on both said legs of the respective first plug-in part and/or of the respective second plug-in part within the respective leg plug-in receptacle, and are integrally connected to the respective leg, and protrude into the respective leg plug-in receptacle. The positive ribs can furthermore be configured to be cut and/or peeled and/or plastically deformed by means of the heat exchanger when attaching a respective plug-in part onto the heat exchanger, whereby the first plug-in part and/or the second plug-in part are wedged on the heat exchanger detachably or non-detachably as well as without play. A preferred embodiment is thus specified, by means of which a positive connection between a first plug-in part and/or a second plug-in part and the heat exchanger is optimized.
To make the first and second plug-in parts, which are mechanically stressed in particular by their installation on the heat exchanger and/or handling, such as transport and storage, resistant, it can advantageously be provided that the first and second plug-in parts are each equipped with support struts, which connect the legs of the respective plug-in parts to one another, so that a mutual support of the legs and thus a reinforcement of the first and second plug-in part is attained. The support struts can thereby each be integrally connected to the legs. They can reach, for example, from one leg end of the one leg to the middle of the other leg of the respective first plug-in part and/or second plug-in part.
It is advantageous when the two lateral enclosures combined do not enclose the complete circumferential edge of the heat exchanger. In other words, the two lateral enclosures each only enclose a section of the circumferential edge of the heat exchanger, which is smaller than the complete circumferential edge of the heat exchanger. The circumferential edge of the heat exchanger can advantageously be formed by means of cohesive narrow surfaces of the heat exchanger. It can furthermore be provided that the two lateral enclosures combined enclose at least 25% of the circumferential edge of the heat exchanger, and/or that the two lateral enclosures combined maximally enclose 50% of the circumferential edge of the heat exchanger. It can also be provided that the lateral enclosures each completely enclose a section of the heat exchanger, which is aligned vertically with respect to a ground, on which the vehicle is parked, in particular a vertical narrow short surface of the heat exchanger, as well as each enclose at least 10% and maximally 20% of two sections, which are aligned horizontally with respect to the ground and which are arranged parallel to one another, in particular each a horizontal narrow long surface of the heat exchanger. A preferred design for the two lateral enclosures is thus specified.
In order to lock a first plug-in part in a positive manner with a second plug-in part, it can advantageously be provided that a pair of locking protrusions is arranged on the first plug-in part, and a pair of locking receptacles, which is formed complementary with respect to said locking protrusions, is arranged on the second plug-in part, or vice versa. Locking protrusions and locking receptacles can be locked or are locked with one another and form a first clip connection for connecting the first plug-in parts in a positive manner to the second plug-in parts. It is furthermore advantageous when, in the installed state of the heat exchanger assembly, at least one pair of locking protrusions is locked into position with a pair of locking receptacles. A positive locking, which is simple from a structural aspect, of a first plug-in part with a second plug-in part can thus be provided.
The first clip connection advantageously forms a locking connection, wherein the locking protrusions and the complementary locking receptacles are configured to form a positive, detachable or non-detachable connection by inserting and locking the locking protrusions into position with the locking receptacles. In particular the use of additional connecting means, such as, for example, adhesives or fastening screws, can thus be forgone.
During the installation of the heat exchanger assembly, a pair of locking protrusions is advantageously inserted into a complementary pair of locking receptacles in a joining direction, wherein locking lugs, which are integrally arranged on the respective locking protrusions and which protrude away from the respective locking protrusions, lock into position with a respective locking receptacle, so that said first clip connection is locked, and a removal of the locking protrusions from the locking receptacles opposite to the joining direction is blocked. The first clip connection can advantageously be unlocked by means of, for example, manual actuation.
It is advantageous when the lateral enclosures or the first plug-in parts and/or the second plug-in parts are arranged in a fluid-tight manner on the heat exchanger. The first plug-in parts and/or the second plug-in parts can advantageously have a sealing means, which is connected between the respective first plug-in part or the respective second plug-in part and the heat exchanger. Said plug-in parts are thus in each case equipped with a sealing function, so that fluid, for example, cannot unintentionally flow through between the respective plug-in part or the respective lateral enclosure, respectively, and the heat exchanger.
It can furthermore be provided that a passage for a connecting piece of the heat exchanger is limited or formed at least between a first plug-in part and a second plug-in part of a lateral enclosure. It can be provided thereby that said passage passes through a first clip connection of the respective lateral enclosure and/or that said passage is flanked on both sides by locking protrusions and locking receptacles of the respective lateral enclosure. An embodiment is thus specified for the lateral enclosures, which also takes into consideration connecting pieces of the heat exchanger. The lateral enclosures can thus be used flexibly.
It can advantageously be provided that the lateral enclosures or the first plug-in parts and/or the second plug-in parts and/or the fixing parts are made of:
Preferred embodiments for plug-in parts are thus specified, which are characterized in particular by a low dead weight and a relatively high mechanical strength.
It can in particular be provided that the first and second plug-in parts are each realized as monolithic components, they can be realized, for example, as injection molded parts.
It can advantageously be provided that the first plug-in parts or the second plug-in parts have an interface, which is referred to as second clip connection, by means of which the fixing part of a lateral enclosure and the respective first plug-in part or the respective second plug-in part can be locked or are locked with one another in a positive manner. The second clip connection can advantageously be equipped with a retaining means for the fixing part, which does allow for a mobility of the fixing part relative to the first plug-in part or second plug-in part, but which prevents a complete detaching from the first plug-in part or second plug-in part. The fixing part can thus not accidentally get lost, for example when it is pre-installed on the first plug-in part or second plug-in part on the supplier-side. The retaining means can be realized in particular by means of a ramp, which is arranged on the first plug-in part or second plug-in part and which is oriented at an angle with respect to the main extension of the first plug-in part or of the second plug-in part. Two mirror-symmetrical ramps, which are arranged on opposite sides of the first plug-in part or second plug-in part, are advantageously provided on the first plug-in part or second plug-in part. The fixing part can cooperate with the ramp or the two mirror-symmetrical ramps, respectively, wherein it is initially clipped onto the ramp or ramps, respectively, in an initial position. In the initial position, the fixing part is movably and captively secured on the first plug-in part or on the second plug-in part. The fixing part can be adjusted from the initial position into a fixing position, for example manually by hand. The fixing part thereby glides along the ramp or the two ramps, respectively, until it reaches a fixing position, in which the fixing part is jammed without play to the first plug-in part or the second plug-in part by means of the ramp or ramps, respectively.
Advantageously, the fixing part per se is a monolithic body, in particular on one end comprising a locking means for the clip-on and locking of the fixing part with an interface of a first plug-in part or of a second plug-in part, in particular the said second clip connection or a fixing part receptacle of a plug-in part, as well as, on the other end comprising a structural part interface for fixing the fixing part to the vehicle. The fixing part can furthermore be equipped with a catch lock, which secures the fixing part in said fixing position against unintentional actuation, a locking connection can advantageously be used, for example by means of a locking window arranged on the fixing part, and a locking lug, which is formed in a complementary manner and which is arranged on the first plug-in part or on the second plug-in part, or vice versa. The installation of the heat exchanger assembly can be simplified by means of the separate fixing part.
It can advantageously also be provided that the fixing parts are each arranged on a section, which is aligned vertically with respect to a ground, on which the vehicle is parked, of the first plug-in part and/or of the second plug-in part. In the installed state of the heat exchanger assembly, the fixing parts are thus quasi arranged laterally on the heat exchanger.
It can further advantageously be provided that the fixing parts are each arranged on a section, which is aligned horizontally with respect to a ground, on which the vehicle is parked, of the first plug-in part and/or of the second plug-in part. In the installed state of the heat exchanger assembly, the fixing parts are thus quasi arranged on the top or on the bottom of the heat exchanger.
It can furthermore be provided that the first plug-in parts are realized by means of identical parts or that the second plug-in parts are realized by means of identical parts. Alternatively, the first plug-in parts and the second plug-in parts can also be realized by means of identical parts. The first plug-in parts and/or the second plug-in parts can thus be provided relatively cost-efficiently.
It can advantageously be provided that the first plug-in parts and/or the second plug-in parts are equipped with additional functional parts, for example clipped-in or screwed-on or welded-on holders for additional functional components and/or electrical lines and/or fluidic lines or uncoupling elements. The first plug-in parts and/or the second plug-in part can furthermore be equipped with an internal spring element, which is in each case elastically tensioned onto the heat exchanger. The first plug-in parts and/or the second plug-in parts, thus quasi the lateral enclosures, can thus be equipped with additional functions.
It can furthermore be provided that at least one in particular metallic holder is soldered to the heat exchanger, by means of which at least one lateral enclosure can be fixed or is fixed to the heat exchanger. The lateral enclosures can additionally be fixed to the heat exchanger by means of the holding means. With their help, for example the positive connection between lateral enclosures and heat exchanger can be supported.
According to a further basic idea of the invention, it is provided to install at least one above-described heat exchanger assembly into a vehicle. For this purpose, a vehicle is proposed, which is equipped with at least one installed heat exchanger assembly according to the preceding description, the heat exchanger of which is realized by means of a coolant radiator or a condenser. The at least one heat exchanger assembly is fixed to a structural component of the vehicle by means of its two lateral enclosures. An advantageous vehicle comprising at least one heat exchanger assembly is thus specified.
It can also be provided that the locking of the plug-in parts by means of their locking protrusions and locking receptacles takes place simultaneously or as part of an operating step with the described caulking of the plug-in parts with the heat exchanger for realizing a positive connection.
In summary, it is important to note: The present invention advantageously relates to a heat exchanger assembly for a vehicle, having a heat exchanger and two lateral enclosures, which hold the heat exchanger and which are arranged on opposite sides of the heat exchanger in order to each enclose a section of a circumferential edge of the heat exchanger. The lateral enclosures each have a first plug-in part, which is fixed in a positive manner to the heat exchanger, a second plug-in part, which is likewise fixed in a positive manner to the heat exchanger, as well as a fixing part, which is arranged on the first plug-in part and/or on the second plug-in part, for fixing the respective lateral enclosure to the structural component. It is essential that the first plug-in parts can be locked or are locked in a positive manner with the second plug-in parts. The invention relates in particular to a vehicle comprising at least one such heat exchanger assembly.
Further important features and advantages of the invention follow from the subclaims, from the drawings, and from the corresponding figure description on the basis of the drawings.
It goes without saying that the above-mentioned features and the features, which will be described below, cannot only be used in the respective specified combination, but also in other combinations or alone, without leaving the scope of the present invention.
Preferred embodiments of the invention are illustrated in the drawings and will be described in more detail in the following description, whereby identical reference numerals refer to identical or similar or functionally identical components.
In Each Case Schematically,
In addition to the heat exchanger 3, the heat exchanger assembly 1 has two separate lateral enclosures 4, 5, which are designed in an approximately u-shaped manner and which are arranged on the heat exchanger 3 on sides 7 of the heat exchanger 3, which are opposite one another in the X direction 44, in particular in sections on said narrow surfaces 58, and which each extend in the Y direction 46, which could be referred to as main extension of the lateral enclosures 4, 5. They each enclose a section 9 of the circumferential edge 8 of the heat exchanger 3, one could also say they encompass the heat exchanger 3 in sections in such a way that the latter is held firmly. The heat exchanger 3 is thus completely immobile with respect to the lateral enclosures 4, 5. Viewed with respect to its length, a respective section 9 is smaller than the circumferential edge 8 of the heat exchanger 3. For example, its respective dimension, i.e. advantageously its length, is less than 50% of the dimension of the circumferential edge 8, its respective dimension is further for example more than 25% of the dimension of the circumferential edge 8. The lateral enclosures 4, 5 are configured to jointly fix the heat exchanger assembly 1 detachably or non-detachably to a structural component 10 of the vehicle 2, which, for reasons of simplicity, is suggested only by means of a symbolic, dashed line in
In an exemplary manner, the lateral enclosures 4, 5 are constructed modularly of a first, separate plug-in part 11, which is fixed in a positive manner to the heat exchanger 3, a second separate plug-in part 12, which is likewise fixed in a positive manner to the heat exchanger 3, as well as a separate fixing part 13, which is arranged in an exemplary manner on the second plug-in part 12 and which serves the purpose of fixing the respective lateral enclosures 4, 5 to said structural component 10. The first plug-in parts 11 and the second plug-in parts 12 are each of approximately L-shaped design. The first plug-in parts 11 are realized as identical parts herein. The second plug-in parts 12 as well as the fixing parts 13 are also realized as identical parts herein.
It can be seen in
To establish said positive connections between the plug-in parts 11, 12 and the heat exchanger 3, it is provided that the first plug-in parts 11 and the second plug-in parts 12 are each attached to the heat exchanger 3, in the Z direction 47 herein, wherein the first plug-in parts 11 and the second plug-in parts 12 are or will be fixed in a positive manner to the heat exchanger 3 by means of caulking with the heat exchanger 3. By means of the caulking, at least one positive connection 14 is provided on the heat exchanger assembly 1, which could also be referred to as caulking connection. In any event, the respective positive connection 14 is characterized in that the respective first plug-in part 11, which is made of softer material with respect to the heat exchanger 3 and the respective second plug-in part 12, which is likewise made of softer material with respect to the heat exchanger 3, is cut and/or partially peeled and/or plastically deformed by means of the heat exchanger 3, which is made of harder material and which is produced in all-aluminum construction, as mentioned above. As a result, said plug-in parts 11, 12 wedge or jam with the heat exchanger 3. The respective first plug-in part 11 and the respective second plug-in part 12 are thus held or fixed in a positive manner with the heat exchanger 3 detachably or non-detachably as well as without play with respect to the X direction 44, the Y direction 46, as well as the Z direction 47.
To make the first and second plug-in parts 11, 12, which are mechanically stressed in particular by their installation on the heat exchanger 3 and/or handling, such as transport and storage, resistant, the first and second plug-in parts 11, 12 are each equipped with support struts 26. They mutually reinforce the legs 15, 16 or realize a mutual support, respectively, see in particular
With reference to
One said pair of locking protrusion 28 is advantageously inserted into a complementary pair of locking receptacles 29 in a joining direction 62, which runs in parallel with the X direction 47 and the secondary axis 61 and which is suggested by an arrow in
It can be seen in particular in
The lateral enclosures 5, 6 or the second plug-in parts 12, respectively, additionally have a further interface, which is referred to herein as second clip connection 34, which are made up of fixing part receptacles 63 arranged on the plug-in parts 12 and the mentioned fixing parts 13 of a lateral enclosure 4, 5. The fixing parts 13 and the respective second plug-in parts 12 can be locked easily with one another in a positive manner by means of the second clip connections 34, for example manually by hand, see in particular
The fixing parts 13 are furthermore equipped in an exemplary manner with a tab-like catch lock 51, which can be deflected transverse to the secondary axis 61, comprising a locking window 66 and which can secure the respective fixing part 13 in an additionally described fixing position 39, against unintentional actuation in the direction of the secondary axis 61 by means of a complementary locking lug 65 of the second plug-in part 12. Said fixing part receptacles 63 are equipped in an exemplary manner with a retaining means 52 for a fixing part 13, which allows for a mobility of the fixing part 13 relative to the second plug-in part 12 in an initial position 38, but which prevents a complete detaching of the fixing part 13 from the second plug-in part 12 in the initial position 38, see in particular
The first plug-in parts 11 and/or the second plug-in parts 12 can furthermore be equipped with an internal spring element 42, which is in each case elastically tensioned onto the heat exchanger 3, see in particular
