Abstract

The vehicle heating system has special floor and wall panels inside which the heating fluid is ducted in arrays of pipes, which are covered with a thermally transmitting trim. The pipes are located in U-shaped ducts embedded in a heat retaining plastics foam, which forms the main body of the panels. The foam ensures that the heating effect drops off gradually when the vehicle is stopped, providing passenger comfort, e.g. at the ends of bus runs. The U-shaped ducts are in good thermal contact over half the surface of the pipes and are located by notches pressed into the outer side of the panels to hold the ducts away from the outer edges.

Description

"Fahrgastraumheizung für Kraftfahrzeuge',"Passenger compartment heating for motor vehicles",

Die Erfindung betrifft eine Fahrgastranmheizung für Kraftfahrzeuge, bei der der Wärmeträger in nach oben hin durch den wärmeabgebenden Fahrzeugboden abgedeckten Rinnen geführt wird, die auf einem unteren Bodenteil aufliegen, und wobei der Hohlraum zwischen den Rinnen durch einen Isolierstoff ausgefüllt isi.The invention relates to a passenger rail heater for motor vehicles, in which the heat transfer medium in upwards through the heat-emitting vehicle floor covered gutters, which rest on a lower floor part, and whereby the cavity between the grooves is filled with an insulating material.

Eine derartige Heizeinrichtung, bei der erwärmte Frischluft als Wärmeträger Verwendung findet, ist durch die DD-PS 10 230 bekannt. Da hierbei die Kanäle endseitig mit der Außenluft in Verbindung stehen und nach dem Abstellen der Brennkraftmaschine und dem Ausschalten des die Warmluft fördernden Geläses kein weiterer Wärmenachschub mehr erfolgt, kühlt der Innenraum trotz der vorgesehenen Isoliermaßnahmen verhältnismäßig rasch ab, was auch noch dadurch begünstigt wird, daß zwischen den unteren Kanalwänden und dem unteren Bodenteil große Wärmebrücken vorhanden sind Es ist Aufgabe der Erfindung, eine Heizeinrichtung zu schaffen, die aufgrund eines guten Wärmeüberganges eine rasche Aufheizung des Innenraumes erbringt und die sich durch einen geringen Wärmeverlust auszeichnet, so daß auch bei abgestellter Heizung wegen des das verwendete Heizmedium auszeichnenden hohen Wärmeinhaltes eine vorzeitige Auskühlung des Innenraumes verhindert wird.Such a heating device in which heated fresh air is used as a heat transfer medium Is used is known from DD-PS 10 230. Since here the channels are at the ends are in communication with the outside air and after switching off the internal combustion engine and the switching off of the hot air-promoting gel no further heat supply If more is done, the interior cools relatively despite the insulation measures provided quickly, which is also favored by the fact that between the lower channel walls and there are large thermal bridges in the lower part of the floor. to create a heating device that has a good heat transfer rapid heating of the interior and which results from a low heat loss so that even when the heating is switched off because of that The heating medium used is characterized by its high heat content and premature cooling the interior is prevented.

Deshalb wird eine Fahrgastraumheizung der eingangs genannten Art vorgeschlagen, die erfindungsgemäß die Kombination der folgenden Merkmale umfaßt: a) die Rinnen nehmen untereinander verbundene Rohre aus einem elastischen Material auf, die mit mindestens der Hälfte ihres Umfanges an der Rinnenwandung anliegen und in denen aufgeheizte Flüssigkeit, insbesondere Kühlwasser zirkuliert.Therefore, a passenger compartment heating of the type mentioned is proposed, which according to the invention comprises the combination of the following features: a) the channels take interconnected pipes made of an elastic material, with at least half of their circumference rest against the channel wall and in which heated liquid, especially cooling water, circulates.

b) als Fahrzeugboden dient im Bereich der nach oben hin offenen Rinnen ein wärmedurchlässiger Belag, der auch die übrige Fläche des Fahrzeugbodens bedeckt und c) der untere Bodenteil ist mit in Richtung der Unterseite der Rinnen hochragenden Absätzen, z. B. in Form herausgedrückter Warzen versehen, über die nur eine örtliche Verbindung mit den Rinnen erfolgt.b) serves as the vehicle floor in the area of the upwardly open grooves a heat-permeable covering that also covers the remaining area of the vehicle floor and c) the lower floor part protrudes towards the underside of the gutters Paragraphs, e.g. B. provided in the form of squeezed out warts, over which only a local Connection with the gutters takes place.

Eine große Tragfähigkeit und damit die Möglichkeit einer vormontierten Baugruppe ist gegeben, wenn-der Isolierstoff aus Polyurethan-Schaum besteht, der auch die seitlich durch die Absätze begrenzten Zwischenräume unterhalb der Unterseite der Rinnen ausfüllt.A large load capacity and therefore the possibility of a pre-assembled Assembly is given if-the insulating material consists of polyurethane foam, the also the spaces below the underside, bounded laterally by the heels fills the gutters.

Beim Einsatz der erfindungsgemäßen Fahrgastraumheizung in einem Großraumfahrzeug, insbesondere Omnibus ist eine Anhebung der Heizleistung auf einfache Weise dadurch möglich, daß auch in senkrecht verlaufenden Abschnitten des Fahrzeugbodens und/oder der Seitenwand Rinnen mit darin eingelassenen Rohren zu Heizzwecken angeordnet sind.When using the passenger compartment heating according to the invention in a large vehicle, In particular, the omnibus is a simple way of increasing the heating power possible that also in vertically extending sections of the vehicle floor and / or the side wall gutters are arranged with pipes embedded therein for heating purposes.
