Description

The invention relates to a capacitor for a vehicle, in particular for a motor vehicle, according to the preamble of patent claim 1.

Such capacitors for vehicles, in particular motor vehicles, are already well known from the general state of the art and in particular from the production of standard vehicles. The respective condenser is used to cool, for example, a fluid designed as a refrigerant and thereby to condense it. For this purpose, the capacitor has juxtaposed, spaced-apart and can be flowed through by the fluid flat tubes, via which the fluid can be cooled. Since the flat tubes are spaced from each other, respective gaps are provided between the flat tubes. The spaces can be traversed along a passage direction of air. In the interstices slats are arranged, which are also referred to as ribs or corrugated ribs. The lamellae can be flowed around by the air flowing through the intermediate spaces, with the air flowing through the intermediate spaces also flowing around and around the flat spaces.

In addition, the disclosed DE 10 2007 007 607 A1 a protective device for a heat exchanger of a motor vehicle.

Object of the present invention is to develop a capacitor of the type mentioned in such a way that the capacitor can be protected in a particularly simple manner from unwanted damage and resulting leaks.

This object is achieved by a capacitor having the features of patent claim 1. Advantageous embodiments with expedient developments of the invention are specified in the remaining claims.

In order to develop a capacitor specified in the preamble of claim 1 type such that the capacitor can be particularly effective and in a particularly simple and thus cost-effective manner from unwanted damage and resulting, also known as capacitor leakage leaks, it is according to the invention provided that in at least one of the intermediate spaces at least one support element is arranged, which projects beyond the flat tubes along the passage direction on both sides. In other words, the support elements along the passage direction on both sides over the flat tubes, so that a two-sided projection of the support member is provided with respect to the flat tubes. If, for example, force application occurs, in particular, at least along the passage direction, so that, for example, a first component of the vehicle arranged along the passage direction on a first side of the capacitor is displaced along the direction of passage in the direction of the condenser and in the direction of a second component which is located on a first component arranged along the passage direction of the first side facing away from the second side of the capacitor, so for example, the first component can be supported on the support element.

Direct contact between the first component and the flat tubes or between the first component and the fins can be avoided. If there is also a displacement of the capacitor in the direction of the second component, the capacitor can be supported on the second component via the support element, so that direct contact between the second component and the flat tubes or between the second component and the lamellae is avoided can. As a result, the accidental application of force can be transmitted or derived via the support element, bypassing the flat tubes and the slats. This means that the example formed as a socket support member is applied, that is loaded, so that excessive loads on the flat tubes and the fins can be avoided. This can prevent the flat tubes from being hit directly by the components and thus being crushed or deformed so much that leaks occur. In addition, the support element designed as a socket, for example, can prevent the penetration of foreign bodies into the tubes, so that the risk of leakage of the capacitor can be kept particularly low. As a result, it can be prevented that the fluid formed as, for example, a refrigerant emerges from the condenser. Furthermore, the invention makes possible a contribution to passive mitigation for the condenser designed, for example, as an air condenser. Especially with minor accidents, excessive damage to the capacitor can be avoided.

The support member may for example be formed of a metallic material, in particular of steel, so that the support element is formed for example as a steel bushing. Furthermore, it is conceivable that the metallic material is aluminum, so that the support element can be designed, for example, as an aluminum bushing. By using aluminum, unwanted corrosion can be avoided. Other materials from which the support member may be formed are readily possible. Also the geometry of the support element as well as the number of support elements can be made flexible.

The first component is, for example, a bending cross member, wherein the second component may be an example designed as an internal combustion engine drive motor. By means of the support element, it is possible to avoid that the capacitor is squeezed between the components. As a result, unwanted leakage of the capacitor can be avoided. Preferably, in the at least one intermediate space, in a plurality of the intermediate spaces or in all interspaces, a plurality of support elements, to which the previous and following statements can be transmitted to the at least one support element and vice versa. As a result, the capacitor can be protected in a particularly effective and cost-effective manner.

Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or in the figures alone can be used not only in the respectively specified combination but also in other combinations or in isolation, without the scope of To leave invention.

1 shows a detail in a schematic front view, for example, designed as an air condenser capacitor 10 for a motor vehicle, which is designed, for example, as a motor vehicle, in particular as a passenger car. In its completely produced state, the vehicle has, for example, at least one first component, not shown in the figures, which is designed, for example, as a bending cross member. Here is the capacitor 10 For example, in the vehicle longitudinal direction towards the front at least partially covered by the first component. Thus, the first component in the vehicle longitudinal direction on a first, in particular in the vehicle longitudinal direction forward facing side of the capacitor 10 arranged. Furthermore, the motor vehicle in its completely manufactured state comprises at least one second component which is not shown in the figures and which, for example, can be designed as a drive motor, in particular as an internal combustion engine, of the motor vehicle. The motor vehicle can be driven by means of the drive motor. The second component is on one of the first side in the vehicle longitudinal direction opposite or opposite the second side of the capacitor 10 arranged so that, for example, the capacitor 10 in the vehicle longitudinal direction towards the rear is at least partially covered by the second component.

The capacitor 10 has several, juxtaposed and spaced apart flat tubes 12 on, which can be traversed by an example of a refrigerant designed as an air conditioning fluid or during operation of the capacitor 10 be flowed through. The capacitor 10 is used to cool the fluid and thus cause condensation of the fluid. This can be the flat tubes 12 flowing fluid through the flat tubes 12 be cooled, which will be explained in more detail below. The flat tubes 12 are along a in 1 by a double arrow 14 illustrated direction next to each other or arranged successively and thereby spaced from each other, wherein, for example, in the installed position of the capacitor 10 by the double arrow 14 illustrated direction coincides with the vehicle vertical direction. It takes the capacitor 10 its installation position in the fully manufactured state of the vehicle. Because the flat tubes 12 are spaced apart, are between the respective flat tubes 12 respective gaps 16 arranged or formed. For example, the spaces are 16 along the by the double arrow 14 illustrated direction on both sides by the respective flat tubes 12 limited. The between the flat tubes 12 arranged spaces 16 can along a in 1 through an arrow 18 flow direction through which air flows. The passage direction extends, for example, perpendicular to the through the double arrow 14 illustrated direction, wherein the passage direction in installation position of the capacitor 10 For example, coincides with the vehicle longitudinal direction. In particular, during the forward travel of the vehicle can resulting from wind air resulting air along the passage direction and thereby in the vehicle longitudinal direction from front to back through the interstices 16 flow through, so that the spaces between them 16 air flowing through the flat tubes 12 flows around and around. As a result, for example, a particularly advantageous heat transfer from the fluid flowing through the flat tubes via the flat tubes 12 to the flat tubes 12 on and around and through the interstices 16 air flowing through. As a result, the fluid is cooled so that condensation of the fluid can be effected.

To a particularly large surface of the capacitor 10 realize and be able to cool the fluid particularly well in the sequence, are in the respective spaces 16 respective slats 20 of the capacitor 10 arranged. The slats 20 For example, heat transfer with the respective flat tubes 12 connected, so in a particularly advantageous manner heat from the fluid to the flat tubes 12 and from the flat tubes 12 to the slats 20 can go over. The the gaps 16 flowing air flows through the fins 20 or flows around the fins 20 so that the slats 20 and about these the flat tubes 12 and thus the fluid by means of the interstices 16 flowing air can be cooled particularly advantageous. In other words, the slats are 20 from the spaces between 16 flowing air flowing around and. The slats 20 are also referred to as ribs or corrugated ribs or are formed as ribs or corrugated ribs.

Order now the capacitor 10 In a particularly effective and cost-effective manner, in particular to protect against unwanted damage and consequent capacitor leaks, are in the respective spaces 16 respective support elements 22 arranged. How very good 2 can be seen, dominates the respective support element 22 the respective flat tubes 12 along the passage direction and thus along the vehicle longitudinal direction on both sides, whereby the flat tubes 12 can be protected particularly advantageous against unwanted damage. In 2 For example, the first side on which, for example, the first component is disposed is designated 24, the second side being designated 26. Under the feature that the respective support element 22 the flat tubes 12 is projected on both sides along the passage direction or along the vehicle longitudinal direction, it is to be understood that the respective support element 22 the flat tubes 12 along the passage direction both on the side 24 as well as on the side 26 surmounted. Thus, on both sides 24 and 26 a respective projection of the respective support element 22 with respect to the flat tubes 12 along the passage direction and thus provided along the vehicle longitudinal direction. If, for example, an accidental backward displacement of the first component occurs, then by means of the support elements 22 direct collisions between the first component and the flat tubes 12 be avoided. In such an accidental rearward displacement, the first component in the vehicle longitudinal direction to the rear of the support elements 22 supported. This results in an accidental return displacement of the capacitor 10 , so can also direct contact between the flat tubes 12 and the second component are avoided. The capacitor 10 can do this by means of the support elements 22 be supported in the vehicle longitudinal direction to the rear on the second components. As a result, a particularly advantageous transmission of accidental loads from the first component via the support elements 22 to the second component, so that excessive loads on the flat tubes 12 can be avoided. This can be avoided that the flat tubes 12 be clamped between the components and excessively deformed or otherwise damaged, so that unwanted leakage of the capacitor 10 can be avoided. As a result, leakage of the fluid from the condenser 10 be avoided.

How very good 1 and 2 can be seen, is the respective support element 22 preferably designed as a socket. It has proved to be particularly advantageous if the respective support element 22 is formed of a metallic material, wherein the metallic material is preferably a steel. Thus, the respective support element 22 preferably designed as a steel bushing.
