Abstract

The heat created under the covers by solar radiation, is removed, and discharged outside (3) of the space to be protected from the heat. Removal is by the use of e.g. air, which is passed through hollow spaces (2) under the covers (1). These have good heat conducting characteristics. The instruments concerned are manufactured form separate parts. Some parts carry webs, forming channels. The other parts are suitably fastened to these. The hollow spaces are formed by distance pieces, e.g. pegs, between upper and lower sections. USE/ADVANTAGE - In dashboards of motor vehicles. Reduces heating-up of instruments.

Description

Oberflächen von Bauteilen die der Wärmeeinstrahlung ausgesetzt sind, insbesondere der Armaturenabdeckung in Kraftfahrzeugen.Surfaces of components exposed to heat radiation are, in particular the valve cover in motor vehicles.

Um die an den der Wärmeeinstrahlung, hauptsächlich hinter Verglasungen, ausgesetzten Flächen entstehende Aufheizung zu verhindern, gibt es, am Beispiel eines Kraftwagens, mehrere sehr unvollkommene Möglichkeiten. Die Fenster oder ein vorhandenes Schiebedach können geöffnet werden, mit der Folge von unangenehmer Zugluft und Lärm. Durch Staudruck oder ein Gebläse kann Außenluft zugeführt werden, wobei jeweils Abgase, Ruß und Staub mit eingebracht werden. Aufwendige Klimaanlagen werden ebenfalls eingesetzt, wodurch sich der Energieverbrauch erhöht. Auch ist Wärmeschutzverglasung bekannt, die aber eine geringere Durchlässigkeit für sichtbares Licht als Klarglas aufweist und dadurch besonders bei Dunkelheit nachteilig ist.In order to avoid heat radiation, mainly behind glazing, to prevent exposed surfaces from heating up, using the example of a motor vehicle, several very imperfect options. The windows or an existing sunroof can be opened with the consequence of unpleasant drafts and noise. By back pressure or a blower can be supplied with outside air, exhaust gases, soot and dust can be introduced. Elaborate air conditioners are also used, which increases energy consumption. Also thermal insulation glazing is known, but a lower one Has transparency for visible light as clear glass and is particularly disadvantageous in the dark.

Alle diese Einrichtungen vermögen die Aufheizung bei Sonneneinstrahlung nicht oder nur sehr wenig zu vermindern. Die bestrahlten Flächen sind im Verhältnis zum Innenraum eines Kraftwagens sehr groß. Es wird eine sehr hohe Lufttemperatur erreicht. Durch die Schrägstellung der vorderen und hinteren Verglasung wird die von den aufgeheizten Flächen ausgehende Wärmestrahlung in Richtung der Insassen reflektiert, wodurch die Wirkung einer Klimaanlage stark vermindert wird.All of these devices can heat up in direct sunlight not diminish or very little. The irradiated areas are very large in relation to the interior of a motor vehicle. It will be one very high air temperature reached. By tilting the front and rear glazing is the one emanating from the heated surfaces Heat radiation is reflected towards the occupants, causing the Effect of air conditioning is greatly reduced.

Die Erfindung hat die Aufgabe, die Aufheizung gering zu halten, ohne dadurch Nachteile entstehen zu lassen.The invention has the task of keeping the heating low without thereby creating disadvantages.

Dieses Problem wird durch die Ausbildung der betreffenden Teile nach Anspruch 1 gelöst.This problem is addressed by the training of the parts concerned Claim 1 solved.

Mit der Erfindung wird erreicht, daß die Temperatur an den der Wärmeeinstrahlung ausgesetzten Oberflächen niedrig bleibt. Die entstehende Wärme wird nach außerhalb abgeführt, wodurch die Anlage auch im Verkehrsstau oder hinter qualmenden Fahrzeugen ohne Beeinträchtigung der Insassen in Betrieb bleiben kann. Die Leistungsfähigkeit des Fahrzeugführers bleibt länger erhalten. Wärmeschutzverglasung kann, zumindest im Bereich der Frontscheibe, entfallen. Durch Wahl von nachgiebigem Werkstoff für die Teile der Er­ findung wird zusätzlich der Unfallschutz für die Insassen verbessert. With the invention it is achieved that the temperature to the Surfaces exposed to heat radiation remain low. The Any heat generated is dissipated outside, causing the system even in traffic jams or behind smoking vehicles without Impairment of occupants can remain in operation. The The driver's performance is maintained longer. Thermal insulation glazing can, at least in the area of the windscreen, omitted. By choosing resilient material for the parts of the Er accident protection for the occupants is also improved.  

Besonders bei Fahrzeugen mit dunkler Lackierung empfiehlt sich die Verwendung des Systems auch zwischen Dach und Innenverkleidung.Particularly recommended for vehicles with dark paint the use of the system also between the roof and the interior cladding.

Vorteilhaft ist der Betrieb des Systems zusammen mit einer Klimaanlage, die dann auch mit geringerer Leistung betrieben werden kann. Eine, im Interesse eines niedrigen Luftwiderstandes der Fahrzeuge erstrebenswerte, sehr starke Neigung der Windschutzscheibe und der Heckscheibe wird ebenfalls möglich, ohne daß eine wesentliche Aufheizung der darunter liegenden Flächen erfolgt, sofern diese nach der Erfindung ausgebildet sind. Thermostatische Schalter, mit Wärmefühlern an den betreffenden Oberflächen, können das System steuern. Die Stromversorgung des Gebläses kann auch durch fotovoltaische Einrichtungen erfolgen, die dann bei geparkten Fahrzeugen automatischen Betrieb ermöglichen. Wenn Warmluft durch die Kanäle des Systems geleitet wird, kann die Wirkung der Heizung verbessert werden, da dadurch die Oberflächen über den Kanälen sehr schnell erwärmt werden und die anfängliche "Kältestrahlung" in Wärmestrahlung übergeht. Beschlagene oder vereiste Scheiben werden schnell frei.It is advantageous to operate the system together with a Air conditioning, which then operated with lower power can be. One, in the interest of low drag of the vehicles desirable, very strong inclination of the Windshield and the rear window will also be possible without that a substantial heating of the underlying areas takes place if they are designed according to the invention. Thermostatic switches, with heat sensors on the concerned Surfaces can control the system. The power supply of the Blower can also be done by photovoltaic devices which then enable automatic operation in parked vehicles. If warm air is passed through the system ducts, the Effect of heating can be improved as this will make the surfaces can be warmed up very quickly over the channels and the initial "Cold radiation" changes into heat radiation. Studded or icy windows are released quickly.

Die Anwendung der Erfindung, an der Armaturenabdeckung in einem Kraftwagen, zeigt der Längsschnitt in der Zeichnung.The application of the invention to the valve cover in one Motor vehicle, shows the longitudinal section in the drawing.

Die bei (4) eintretende Außenluft wird durch Staudruck oder ein Gebläse durch die Kanäle (2) geführt. Dabei entzieht sie der gut wärmeleitend ausgebildeten Oberfläche (1) die dort entstehende Strahlungswärme und verläßt über Kanal (3) den Innenraum. Der Auslaß (3) wird zweckmäßig in dem Bereich angeordnet, in dem während der Fahrt Unterdruck auftritt.The outside air entering ( 4 ) is led through the channels ( 2 ) by dynamic pressure or a blower. In doing so, it extracts the radiation heat generated there from the surface ( 1 ), which has good thermal conductivity, and leaves the interior via channel ( 3 ). The outlet ( 3 ) is expediently arranged in the area in which underpressure occurs during the journey.
