Description

[0001] The present disclosure relates to a deflection device for deflecting a fluid flow, as well as to a motor vehicle comprising a fluid line with at least one deflection device. The disclosure thus lies in the field of motor vehicles and, in particular, in the field of fluid lines in motor vehicles.

[0002] In motor vehicles, fluid lines are typically used to convey gases and / or liquids within the motor vehicle in the form of a fluid flow. Such fluid flows can include air, for example, for ventilation and / or air conditioning of the vehicle interior. Alternatively or additionally, fluid lines in motor vehicles can be designed to convey a liquid fluid flow, such as water, coolant, cleaning fluid, hydraulic fluid, oil, fuel, and / or lubricant.

[0003] In automotive development, accommodating conventional deflection devices can often be challenging due to the space required for the deflection device and its connections, and can even cause implementation problems. This may require modification of the originally planned vehicle design and result in additional costs and / or compromises in the vehicle design.

[0004] Standardized couplings or connectors are known in the prior art, such as VDA connectors and connectable deflection devices that can deflect a fluid flow by 90°. These usually have the disadvantage of a very large installation height, which entails a significant space requirement in the motor vehicle for the installation of the deflection device, such as the connector described in DE 10 2015 105 422 A1. In addition, special couplings for a 90° deflection of a fluid flow are known. These are optimized in terms of installation space, but do not allow the connection of standardized connectors and are therefore often unsuitable for fluid lines according to a given standardization, such as the transition piece described in DE 10 2009 035 558 A1. Furthermore, US Patent 6,161,876 describes a corner connector that has the aforementioned disadvantages.

[0005] Against the background of this prior art, the object of the present disclosure is to provide a deflection device which is suitable for enriching the prior art.

[0006] The problem is solved by the features of the independent claims. The subordinate claims and the dependent claims each contain optional developments of the disclosure.

[0007] According to this, the problem is solved by a deflection device for deflecting a fluid flow. The deflection device comprises a supply connection with a round line cross-section, wherein the supply connection is connectable to a standardized connector with a round line cross-section. Furthermore, the deflection device comprises a discharge connection with a round line cross-section, wherein the discharge connection is connectable to a standardized connector with a round line cross-section. The deflection device is further characterized in that the deflection device has a deflection nozzle connecting the supply connection and the discharge connection, said deflection nozzle having a line cross-section that is flattened compared to a round line cross-section, said deflection nozzle being designed to deflect the fluid flow by a deflection angle of at least 45° and at most 135°.The cross-sectional area of ​​the rectangular cable cross-section is at least 90% of the cross-sectional area of ​​the supply line connection.

[0008] A deflection device is a device designed to change the flow direction of a fluid stream by a predetermined angle. The deflection angle can be in a range of approximately 45° to 135°, and optionally approximately 90°.

[0009] A supply connection is a connection for the supply of the fluid flow, i.e., a connection through which the fluid flow can flow into the deflection device. Accordingly, a discharge connection is a connection for the discharge of the fluid flow, i.e., a connection through which the deflected fluid flow can flow out of the deflection device.

[0010] A line cross-section can refer to the internal cross-section of the respective connection or nozzle available for conducting the fluid flow. The line cross-section can lie in a cross-sectional plane extending perpendicular to the flow direction of the fluid flow. The line cross-section can be characterized by a cross-sectional shape and / or a cross-sectional area, which can significantly influence the ability to conduct a fluid flow. In particular, the cross-sectional area of ​​the line cross-section can be decisive for the size of the fluid flow that can be conveyed through the respective line.

[0011] A diverter nozzle can be a diverting element in which a flow direction of the fluid stream is changed by the predetermined deflection angle. For this purpose, the diverter nozzle can have a curved and / or angled line. The fact that the diverter nozzle has a line cross-section that is flattened compared to a round line cross-section can mean that the line cross-section has a non-circular cross-sectional shape with an unequal aspect ratio. In other words, a flattening of the line cross-section of the diverter nozzle can be designed such that the line cross-section has a greater extent along a first direction than along a second direction perpendicular to the first direction. In other words, a flattening of the line cross-section of the diverter nozzle can be characterized in that the line cross-section has a greater width than height.

[0012] The fact that the diverter connects the supply connection and the discharge connection can mean that the diverter diverts the fluid flow flowing in via the supply connection and then forwards it to the discharge connection. The diverter, the supply connection, and the discharge connection can be firmly connected to one another and / or formed as a single piece. In other words, the diverter, the supply connection, and the discharge connection can be formed as a single component.

[0013] The disclosure offers the advantage that the overall height of the deflection device can be kept low, yet standardized connectors can still be connected to the deflection device. This offers the advantage that the deflection device can be used together with conventional, standardized connectors and can be integrated into a conventional fluid line. Thus, a deflection device according to the disclosure can be characterized by compatibility with standardized connectors that have a round line cross-section. Furthermore, the deflection device according to the disclosure offers the advantage that the overall height of the deflection device can be kept low and optimized for a low overall height.This can offer the advantage of simplifying the space required for installing such a deflection device in a motor vehicle, for example, as part of a fluid line, and allowing the deflection device to be installed even in locations where space is at a premium. This can reduce or eliminate problems associated with limited space when planning a motor vehicle.

[0014] Possible further developments of the device described above are explained in detail below.

[0015] The cross-sectional area of ​​the rectangular pipe cross-section of the diverter nozzle can be larger than or equal to the cross-sectional area of ​​the round pipe cross-section of the supply connection and larger than or equal to the cross-sectional area of ​​the round pipe cross-section of the discharge connection. This can offer the advantage that there is no backflow of the fluid flow and no reduction in the flow in the diverter nozzle. Optionally, this can also offer the advantage that there is no mandatory increase or decrease in the flow velocity of the fluid flow in the diverter nozzle. Optionally, the cross-sectional area of ​​the rectangular pipe cross-section of the diverter nozzle can be smaller than the cross-sectional area of ​​the round pipe cross-section of the supply connection and / or smaller than the cross-sectional area of ​​the round pipe cross-section of the discharge connection.

[0016] The flattened cross-section of the diverter nozzle can optionally be rectangular or oval. This can offer the advantage of making the cross-section height smaller than its width. This allows the overall height of the diverter to be kept low. A rectangular cross-section can optionally have rounded corners.

[0017] The pipe cross-section of the diverter nozzle can be flattened such that the aspect ratio of the pipe cross-section is at least 2:1. In other words, the aspect ratio of the pipe cross-section can be designed such that the pipe cross-section of the diverter nozzle is at least twice as wide as it is high. This allows the overall height of the diverter device to be kept low.

[0018] The deflection device can be designed to deflect the fluid flow by a deflection angle of 90° ± 10°. This offers the advantage of achieving a frequently required right-angled deflection of the fluid flow.

[0019] The standardized connector that can be connected to the supply line connection and / or the standardized connector that can be connected to the discharge connection can be designed as one of the following connectors: a VDA connector, an SAE connector, a V-coupling, a Norma Quick coupling, and another conventional, proprietary coupling system. This can offer the advantage that the diverter device can be used in numerous standardized fluid lines. In particular, this can offer the advantage that the diverter device is compatible with connectors that are frequently used in the automotive sector, i.e., in motor vehicles.

[0020] The deflection device can be designed to deflect a fluid flow of at least one of the following fluids: air, gases, water, coolant, cleaning fluid, hydraulic fluid, oil, fuel, and lubricant. The deflection device can optionally be designed and / or optimized for the fluid to be conveyed with regard to its dimensions and / or material properties. Optionally, the deflection device can be designed such that it has at least sufficient chemical resistance and / or temperature resistance and / or mechanical resistance to conduct the intended fluid without being damaged and / or suffering excessive wear.

[0021] The deflection device can optionally be designed for use in a motor vehicle. The deflection device can optionally be adapted to the requirements for use in a motor vehicle with regard to its properties and / or dimensions. Optionally, the deflection device can be designed such that it is compatible with connectors according to one or more standards commonly used in motor vehicles.

[0022] The deflection device can optionally have one or more additional openings, which can be closed with a lid. This can facilitate or enable the manufacture of the deflection device using a casting process.

[0023] The above description can be summarized in other words and in a possible more concrete embodiment of the disclosure as described below, whereby the following description should not be interpreted as limiting the disclosure.

[0024] Installation space problems at the media connections of components and at the connection points of media lines can often lead to problems and doubts about the feasibility of a technical solution within a project when designing a motor vehicle with regard to its fluid lines. Standard couplings with a 90° outlet, such as VDA couplings, are known in the state of the art. Special couplings with a 90° outlet are also known in the state of the art, which optimize the installation space requirements in the area of ​​the coupling. Neither solution optimizes the media redirection. Standard couplings are tall. Special couplings require non-standardized assembly processes, safeguards, and interface components on the connecting component. Therefore, a combination of a standard coupling interface with a space-optimized media guide or redirection is proposed.The media guide can be converted from a round cross-section to a flat, free-form cross-section of the same or similar cross-sectional area. For example, the round cross-sections can have a cross-sectional area with a diameter of d = 20 mm, resulting in a cross-sectional area of ​​314 mm. 2 The rectangular cross-sectional area can optionally have an extension of 10 mm x 32 mm with a cross-sectional area of ​​320 mm 2 to which a standard connection with a round cross-sectional area with a diameter of d = 20 mm can be connected. This can be implemented using lost cores and / or using split and subsequently joined component halves and / or using an additional cover.

[0025] In a further aspect, a motor vehicle comprising a fluid line with at least one deflection device according to the disclosure is provided. All disclosures relating to the deflection device are also to be considered disclosed for the motor vehicle and vice versa. The above description with reference to the deflection device applies analogously to the motor vehicle and vice versa. The motor vehicle can be a passenger car, in particular an automobile, or a commercial vehicle, such as a truck. Furthermore, an aircraft, a construction machine and / or an industrial plant comprising a fluid line with at least one deflection device according to the disclosure is provided.

[0027] The Fig. 1A and Fig. 1B show a deflection device 10 for deflecting a fluid flow according to an optional embodiment in a perspective view ( Fig. 1A) and a cross-sectional view. The deflection device 10 has a supply connection 12 with a round line cross-section, wherein the supply connection 12 can be connected to a standardized connector with a round line cross-section 120. In addition, the deflection device 10 has a discharge connection 14 with a round line cross-section 140, wherein the discharge connection 14 can be connected to a standardized connector with a round line cross-section. The deflection device further has a deflection nozzle 16 connecting the supply connection 12 and the discharge connection 14 and having a line cross-section 160 that is flattened compared to a round line cross-section, wherein the deflection nozzle 16 is designed to deflect the fluid flow by a deflection angle of at least 45° and a maximum of 135°. The cross-sectional area of ​​the rectangular cable cross-section 160 is at least 90% of the cross-sectional area of ​​the supply line connection 12.

[0028] The cross-sectional area of ​​the rectangular line cross-section 160 of the diverter nozzle 16 can be larger than or equal to the cross-sectional area of ​​the round line cross-section 120 of the supply connection 12 and optionally larger than or equal to the cross-sectional area of ​​the round line cross-section 140 of the discharge connection 14. The flattened line cross-section 160 of the diverter nozzle can be rectangular or oval. Optionally, the line cross-section 160 of the diverter nozzle 16 is flattened such that an aspect ratio of the line cross-section is at least 2:1. Optionally, the line cross-section 160 of the diverter nozzle 16 is flattened such that an overall height 100 of the diverter device 10 is kept low.

[0029] The deflection device according to the optional embodiment shown is designed to deflect the fluid flow by a deflection angle of 90° ± 10°.

[0030] A standardized connector that can be connected to the supply port 12 and / or a standardized connector that can be connected to the discharge port 14 can optionally be designed as a VDA connector, an SAE connector, or a V-coupling.

[0031] The deflection device 10 can be designed to deflect a fluid flow of at least one of the following fluids: air, water, cooling fluid, cleaning fluid, hydraulic fluid, oil, fuel, and lubricant. Optionally, the deflection device 10 can be adapted for use in a motor vehicle 300 (see Fig. 3) be designed.

[0032] The Fig. 2A and Fig. 2B show a deflection device 10 according to a further optional embodiment. This differs from the embodiment according to the Fig. 1A and Fig. 1B in that the deflection nozzle has an opening 18, which is closed with a cover 20. This can simplify or enable the manufacture of the deflection nozzle 16 and thus of the deflection device 10 by means of a casting process and thereby reduce manufacturing costs.
