    BACKGROUND OF THE INVENTION Background of the Invention The present invention relates to a display unit for displaying image data on a display and a method for operating a display unit.
    In modern vehicles, display units with display data for travel data, such as driving speed or other driving parameters, are often displayed on the dashboard. More and more purely digital displays are used, such as TFT monitors or head-up displays, on which the corresponding information or parameters are recorded. However, the heat generated during the operation of the electronic unit for the production of image data (here referred to as image data processor) is problematic, which in the available cramped space for the display unit can only be removed with difficulty. Due to a too high temperature difference between the air in the vehicle's interior and the vehicle display, a precipitation can also appear on the vehicle display, which significantly reduces the readability of the display symbols shown on the vehicle display and thus possibly even negatively affects vehicle safety.
    Description of the invention With this background, the method presented here presents a display unit for displaying image data on a display and a method for operating a display unit according to the main claims. Advantageous designs appear from the respective dependency requirements and the following description.
    The approach presented here creates a display unit for displaying image data on a display, the display unit having the features of claim 1.
    A display unit can be understood, for example, as an (electronic) instrument for converting (electrical) image data into optically visible display symbols. These display symbols can be displayed optically by means of a display. With such a display, for example, a TFT monitor or an LED monitor can be understood. With a housing, for example, a plastic shell can be understood, which provides protection of the electronic construction parts arranged in the housing against mechanical damage or contamination. By an air line element can be understood an element which has a projection, a nose or a surface which constitutes a resistance to flowing air and thus can redirect the air part flow formed from this flowing air in a different direction. An air duct element can also be understood to mean an air window, an air guide duct, a guide vane or a hinge rib in a housing (lid). The air duct element can also comprise a plurality of elements separated from each other. within a tolerance range of, for example, 10%) 45 °, 90 ° or 180 ° is understood.
    The approach presented here is based on the insight that by redirecting the flow direction of the air stream, as large an area of the display as possible can be reached by the flowing air of the air stream. In this way, as large a part as possible of the display can be tempered sufficiently, in particular cooled, so that the probability of incorrect display of display symbols on the display can be greatly reduced or completely avoided. The approach presented here thus provides the advantage that through technically very simple and cost-effective realized measures can significantly improve the security of the display of display symbols on the display.
    An embodiment of the approach presented here is also advantageous, in which the display with respect to the flow direction of the air flow is arranged the intermediate air line element and the air outlet opening. Such an embodiment of the approach presented here gives the advantage that the air bypassing the air can be discharged directly via the air outlet opening, so that a high cooling effect can be achieved during the cooling of the display.
    An embodiment of the approach presented here is also conceivable, in which the air inlet opening (or a further) air inlet opening and the air outlet opening are arranged on opposite sides of the housing. Such an embodiment of the approach presented here enables in particular a convection and diversion of heated air, in particular when the air outlet opening is arranged at an upper area of the rejection unit (with respect to the built-in state of the display unit). In this case, one can to a large extent refrain from technically demanding measures to ensure the air flow, such as a fan.
    According to a further embodiment of the approach presented here, the air inlet opening can be arranged on a side of the housing opposite the display. Such an embodiment of the approach presented here provides the advantage of very efficient control of the air flow through the display unit, whereby on the one hand through a path as long as possible the air flow through the display unit a high heat amount is occupied by structural parts of the display unit and at the same time as efficient cooling of large areas of the display take place.
    The display unit according to claim 1 also shows that the air duct element is oriented in such a way that a main stretching plane of the air duct element is aligned substantially parallel to a plane and a main stretching plane of the display, respectively. The approach presented here gives the advantage of a very even cooling of large parts of the display, since the display unit conducts the air flow in a wide channel between the air line element and the display.
    Particularly effective is an embodiment of the approach presented here, in which at least a part of the air duct element is designed to effect a branching of the air bypassing the air duct element into different (sub) air streams, in particular for guiding the air of the different (sub) air streams. Such an embodiment of the approach presented here provides the advantage of being able to cool different elements (or areas of such elements) of the display unit by skillfully controlling the (entire) air flow with different cooling strength, depending on how exposed this element or area of such elements are exposed or "hit" by the air flow.
    According to a further embodiment of the method presented here, the air duct element can be designed to generate a surface air stream from the air stream, in particular to apply at least a main part of the surface of the display streamed by the air stream with air, which has a similar air velocity within a tolerance range. the approach presented here provides that advantage with particularly good planar cooling of a major portion of the airflow inflow display. It is taken into account that the air velocity within the tolerance range (of, for example, 10%) causes as little turbulence as possible and thus a low air resistance.
    When the display unit has an electronic module for providing the image data intended for display, a very advantageous embodiment of the approach presented here can be achieved by the air duct element being configured to direct the air flow with air to the electronic module and / or past the electronic module. In such an embodiment of the approach presented here, an efficient cooling of the electronic module can then also be realized through the air flow already provided. An electronic module can be present, for example, a signal processor for providing or processing the image data to be shown on the display.
    Particularly advantageous in this case is an embodiment of the approach presented here, in which the electronic module has at least one heat sink for cooling an electronic construction element, the air duct element being configured to direct the air flow to and / or past the heat sink. Such an embodiment causes the efficiency of the heat dissipation over the heat sink to rise significantly.
    A particularly high cooling effect has an embodiment of the approach presented here with a fan, which is arranged or directed to transport air from the air inlet opening past the air duct element to the air outlet opening.
    Equally advantageous is an embodiment of the approach presented here as a method for operating a display unit according to an embodiment presented here, the method having the following steps: directing the air flow from the air inlet opening to the air outlet opening past the display, using the air supply element for the line. Even through such an embodiment of the approach presented here, the advantages of the present invention are easily and efficiently realized.
    The approach presented here will be further elucidated with the aid of the accompanying drawings. They show: Fig. 1 a schematic side view of a vehicle with a display unit according to an embodiment of the present invention; Fig. 2 is a detailed cross-sectional view of the display unit of Fig. 1; Fig. 3 is a further cross-sectional view of the display unit according to an exemplary embodiment of the present invention; and Figs. 4 is a flow chart of a method according to an embodiment of the present invention. In the following description of advantageous embodiments of the present invention, the same or similar reference numerals are used for the elements shown and similar in the various figures, whereby a repeated description of these may be omitted. element.
    Fig. 1 shows a schematic side view of a vehicle 100 with a display unit 110 according to an embodiment of the present invention. The display unit 110 is hereby configured to graphically or optically display display symbols on a display 120 for a person 130 present in the vehicle, for example the driver of the vehicle 100. For this purpose, for example, an air inlet opening 140 of the display unit 110 and a housing 145 associated with the display unit 110 may be connected to an air conditioner 150. This air conditioner 150 may, for example, provide cooled air, which is passed through the air inlet port 140 as air stream 153 into the interior of the display unit 110, and is led there by an air line member 155 first to a bottom of the display unit 110 and then in a channel between the air line member 155 and the display 120 upwards. bypass display 120, to exit at least one air outlet opening 165 from the housing 145 of the display unit 110. By redirecting the flow direction of the air from the air stream 153, it can be achieved that the air stream 153 takes as large a path as possible through the housing 145 and and thus can absorb and transport as much waste heat as possible out of the display unit 110.
    In principle, it should further be pointed out that in the present description of the basics of the simpler description only an air inlet opening 140 and an air outlet opening 165 are described. However, without limitation of the technical function as air inlet opening 140 can be understood also a plurality of openings and analogously also as air outlet opening 165 a plurality of openings.
    Fig. 2 shows a detailed cross-sectional view of the display unit 110 from Fig. 1. In this case, the air duct element 155 can be seen, for example, has a main drawing plane, which extends substantially parallel to a main drawing plane of the display 120. Hereby it can be ensured that the air inlet opening 140 opposite the display 120 lying side of the display unit 110, the entry air stream 153 spreads as wide as possible in the duct intermediate air line element 155 and the display 120 and thus a main part crosses the back of the display 120. In this way, as large a heat transfer as possible can take place from the display 120 in the electronic display of the display symbol formed the waste heat in the air of the air stream 153, so that this waste heat can then be dissipated through at least air outlet opening 165. This makes the display 120 as efficient as possible. of only a simple structural part, namely the air duct element 155, is cooled and thus the fault-free function of the display 120 can be ensured as well as possible. The air duct element 155 can be made of metal or of plastic, whereby metal due to a higher thermal conductivity has advantages, however, plastic is technically simpler and thus more cost-effective to manufacture.
    Furthermore, for example, an electronic module 200 may be provided, which is arranged on the side 120 of the air line element 155 facing away from the display 120. The electronic module 200 may be, for example, an image data signal processor, which calculates the display symbols on the display 120 and transmits them over a corresponding interface 210 to the display 120. If the electronic module 200 contains some construction parts, which generate a particularly strong waste heat during operation, these construction parts can be provided with a corresponding cooling body 220, which should protrude as far as possible, in order to come into optimal contact with the air from the air stream 153.
    However, the device (not shown in Fig. 2) of the electronic module 200 on the side facing the display is also conceivable, so that the electronic module 200 is arranged in the duct between the air duct element 155 and the display 120 and is likewise cooled by the air from the air stream 153.
    Furthermore, a further embodiment of the present invention is also advantageous, in which further air inlet openings 230 are arranged in the bottom 160. Through this / these additional air inlet opening (s) 230, for example, additional ambient air can then be sucked in from the outside of the housing 145 into the duct between the air duct 15 and the display 120 (e.g. using the venturi effect). This has on the one hand the advantage that the air of the air stream 153 in the area between the air duct element 155 and the display 120 can be further cooled and on the other hand a larger amount of air passes on the display 120 in the air stream 153 than enters through the (first) air inlet opening 140 into the housing 145 the display unit 110. In this motto, the (further) air inlet opening 230 may be arranged on the side of the housing 145 opposite the air outlet opening 165.
    Alternatively, the additional air inlet opening 230 may also be used as an air outlet opening, for example when the gap between the air duct member 155 and the display 120 is so small that an overpressure would form in the area of the bottom 160 and thus some of the air flows out of the air stream 153. Also in this case an efficient cooling, for example of the electronic module 220 can take place, whereby also the display 120 can be cooled sufficiently.
    The air flow 153 can be effected, for example, by thermal convection, whereby the air in the gap between the air duct member 155 and the display 120 is heated, rises thereby and exits the air outlet opening or air outlet openings 165. The pressure thus formed leads to the air inlet opening 140 and the further air inlet an additional cooling function of the display 120 is performed.
    Alternatively, it is also conceivable to provide a blowing machine in the form of a fan 240, which supports or at all enables the flow of air in the air stream 153. The advantage is maintained that there remains sufficient space in the dashboard, in which the display unit 110 of the vehicle 100 will later be built, in the event of a possible lateral accident with the vehicle 100, the display unit 110 can be broken backwards and thus enabled greater forward movement space for the person 130 present in the vehicle. In this way, the risk of accident for the person 130 present in the vehicle can be further reduced.
    Fig. 3 shows a further cross-sectional view of the display unit 110, this time from a perspective from direction A according to Fig. 2 (in a non-tipped view). In this case, the male air inlet opening 140 is seen as a dashed circle in the middle of the housing 145, into which the air the discharge stream 153 enters. Alternatively or additionally, the air inlet opening 140 (or an additional air inlet opening) may be arranged in the upper area of the housing 145, i.e. on the opposite side of the housing 145 opposite the bottom area 160. This enables a further extension of the air flow path 153 through the passage unit, thereby further improving heat exchange. of the components of the display unit 110 and the air of the air stream 153 can be realized.
    After the entry of the air of the air stream 153 through the air inlet opening 140, the hits on the electronic module 200 and the air duct element 155, respectively, are directed towards the bottom 160 of the housing 145. By bypassing the air stream 153, the waste heat from the electronic module 200 components and from the heat sink 220 is absorbed. the bottom area 160 of the housing 145 enters the air of the air stream 153 into the rear area and rises again, this time in (not shown in Fig. 3) the duct between the duct element 155 and the display 110. To cause as flat air flow 153 as possible in the duct between the duct 155 and 120, ensuring as even a flow rate as possible in all places of this air flow 153, the air duct element may have parts such as air control elements or air guide rails 310, which divide and redirect the air of the air stream 153 in different directions.
    Fig. 4 shows a flow chart of an embodiment of the present invention as method 400 for operating a display unit according to one of the embodiments presented here. The method 400 includes a step 410 of directing the air flow from the air inlet port to the air outlet port past the display, using the air line element for directing the air stream.
    The embodiments described and shown in the figures are only selected as examples. Different embodiments can be combined with each other completely or with respect to individual criteria. An exemplary embodiment can also be supplemented by criteria of a further exemplary embodiment.
    Furthermore, the procedure steps presented here can be repeated and performed in a different manner than in the order described. If an exemplary embodiment comprises an "and / or" interconnection between a first criterion and a second criterion, this means that the exemplary embodiment according to one embodiment has both the first criterion and the second criterion and according to a further embodiment exhibits either only the first criterion or only the second criterion .
