Abstract
Description
Die Erfindung betrifft eine Kondenswasserauffangschale für eine Klimaanlage eines Kraftfahrzeuges mit einem zwischen einem Verdampfer und einem mit kurzem Abstand in Strömungsrichtung nachgeschalteten Heizwärmetauscher gelegenen Bodenabschnitt, der ausgehend von zwei außen angeordneten Ablaufstutzen in Fahrzeugquerrichtung dachförmig verläuft, wobei die wärmetauscherseitige Begrenzungswand als Schwallwand hochgezogen ist.The invention relates to a condensation collecting tray for an air conditioning system of a motor vehicle one downstream between an evaporator and a short distance in the direction of flow Heat exchanger located floor section, which is based on two externally arranged drainage nozzles runs in the shape of a roof in the transverse direction of the vehicle, the boundary wall on the heat exchanger side as a baffle is pulled up.
Eine derart ausgebildete Kondenswasserauffangscha-Ie für eine dachseitig angeordnete Klimaanlage ist durch die DE-OS 32 23 812 bekannt. Die beiden Ablaufstutzen sind unterhalb des Heizwärmetauschers angeordnet und die Schwallwand schließt sich mit Abstand von diesem Wärmetauscher an. Da, um eine Luftabströmung durch die Ablaufleitungen zu verhindern, in diesem stets ein gewisser Wasserstand herrschen muß, kann es zu einer Beaufschlagung zumindest der unteren Lamellen des Heizwärmetauschers durch bei bestimmten Fahrbedingungen hochsteigendes Kondenswassers kommen und außerdem kann nicht verhindert werden, daß es zu einer Unterströmung des Heizwärmetauschers kommt, so daß in beiden Fällen ein Beschlagen der Scheibeninnenseite auftreten kann.A condensation collecting tray designed in this way 32 23 812 is known from DE-OS 32 23 812 for an air conditioning system arranged on the roof side. The two drainage ports are arranged below the heating heat exchanger and the baffle closes at a distance from it Heat exchanger on. In order to prevent air outflow through the drain lines, always in this one If a certain water level has to prevail, at least the lower lamellas can be acted upon of the heating heat exchanger due to rising condensation water under certain driving conditions and in addition, it cannot be prevented that there is an underflow of the heating heat exchanger, so that fogging of the inside of the window can occur in both cases.
Es ist Aufgabe der Erfindung, die Auffangschale so auszubilden, daß selbst dann ein Beaufschlagen von Lamellen durch Kondenswasser und eine Unterströmung des Heizwärmetauschers verhindert wird, wenn es zu einer Ansammlung von Kondenswasser in der Auffangschale kommt.It is the object of the invention to design the drip tray in such a way that even then the lamellae are acted upon is prevented by condensation water and an underflow of the heating heat exchanger when it is too condensation builds up in the drip tray.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.
Eine noch bessere Abschirmung der Lamellen ohne deren Anströmung wesentlich zu verschlechtern wird erreicht, wenn die Oberkante der Begrenzungswand parabelförmig hochgezogen verläuft und der die dahinterliegenden Lamellen des Heizwärmetauschers abdekkende Bereich der Begrenzungswand entgegen der Anströmrichtung abgebogen ist. Die Begrenzungswand ist somit in der Fahrzeuglängsachse am niedrigsten und steigt nach außen hin an, damit auch bei Kurvenfahrt ein Überschwappen des Kondenswassers vermieden wird.An even better shielding of the lamellas without significantly impairing their flow achieved when the upper edge of the boundary wall is raised in a parabolic shape and that behind it The area of the boundary wall that covers the fins of the heating heat exchanger against the direction of flow has turned. The boundary wall is thus lowest in the vehicle's longitudinal axis and rises towards the outside so that the condensation water is prevented from spilling over when cornering.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.
Zur Aufnahme des bei einem Verdampfer 1 einer nicht näher dargestellten Klimaanlage eines Kraftfahrzeuges anfallenden Kondenswassers ist eine Kondenswasserauffangschale 2 vorgesehen, deren zwischen dem Verdampfer 1 und einem in Strömungsrichtung nachgeschalteten Heizwärmetauschers 3 sich erstreckender Bodenabschnitt 4 in Fahrzeugquerrichtung etwa dachförmig verläuft. Das anfallende Wasser strömt somit jeweils nach außen und wird durch zwei dort angesetzte Ablaufstutzen 5, von denen nur einer sichtbar ist, abgeleitet. In nicht dargestellter Weise ist zur Verhinderung einer Luftabströmung das Ende jeder an den Ablaufstutzen 5 angeschlossenen Leitung mit einem bekannten Lippenventil versehen, das sich dann selbsttätig öffnet, wenn eine bestimmte Wasserstandshöhe erreicht ist. Da diese Höhe stark von den Elastizitätsverhältnissen im Bereich der Lippe abhängt, wobei neben der Materialzusammensetzung und der Materialstärke auch die jeweils herrschende Temperatur einen Einfluß ausübt, kann es vorkommen, daß bei ungünstigen Bedingungen sich Wasser in der Kondenswasserauffangschale 2 ansammelt. Damit in einem solchen Fall keine Unterströmung des unteren Wasserkastens 6 des Heizwärmetauschers 3 und auch keine Beaufschlagung dessen Lamellen 7 mit Kondenswasser bei bestimmten Fahrbedingungen eintritt, ist die wärmetauscherseitige Begrenzungswand 8 der Kondenswasserauffangschale 2 als Schwallwand ausgebildet und parabelförmig hochgezogen. Die Oberkante 9 reicht dabei in ihrem mittleren Bereich etwa bis zu den Lamellen 7 hoch, während die überstehenden Außenbereiche zur Wasserrückhaltung und zur Verbesserung der Anströmverhältnisse der Lamellen 7 entgegen der mit Pfeilen angedeuteten Anströmrichtung abgebogen sind.To accommodate the, in the case of an evaporator 1, an air conditioning system (not shown in detail) of a motor vehicle Accumulating condensation water is a condensation collecting tray 2 is provided, which between the Evaporator 1 and a downstream heating heat exchanger 3 in the flow direction extending Floor section 4 runs approximately in the shape of a roof in the transverse direction of the vehicle. The resulting water thus flows each to the outside and is diverted through two drainage nozzles 5 attached there, only one of which is visible. In a manner not shown, the end of each is on the drain connection to prevent air outflow 5 connected line provided with a known lip valve, which then opens automatically, when a certain water level is reached. Since this height depends to a large extent on the elasticity ratios in the Area of the lip depends, in addition to the material composition and the material thickness, the respective prevailing temperature has an influence, it can happen that under unfavorable conditions water collects in the condensation collecting tray 2. So in such a case there is no undercurrent of the lower water tank 6 of the heating heat exchanger 3 and also no exposure to its fins 7 occurs with condensation under certain driving conditions, is the heat exchanger-side boundary wall 8 of the condensation water collecting tray 2 designed as a baffle and pulled up in a parabolic shape. The upper edge 9 extends in its middle area up to about the slats 7 high, while the protruding outside areas for water retention and to improve the inflow conditions of the lamellas 7 are bent against the direction of flow indicated by arrows.
