Abstract
(DE)
Die Erfindung betrifft die Anordnung eines Zusatzheizgerätes (20, 20a, 82, 83) für den Kühlmittelkreislauf einer Brennkraftmaschine eines Kraftfahrzeuges, welcher einerseits aus einem den Kühlmittel-/Luftkühler (1, 70) einschliessenden Kühlkreislauf und andererseits aus einem den Kühlmittel-/Luftwärmetauscher für die Beheizung des Fahrgastraumes einschliessenden Heizkreislauf besteht. Das technische Problem bei Kühlmittelkreisläufen von modernen Motoren, insbesondere Dieselmotoren besteht u.a. darin, daß zu wenig Wärme für die Heizung zur Verfügung steht - insofern werden sogenannte Zusatzheizgeräte, z.B. Brennstoffheizungen eingesetzt. Es wird vorgeschlagen, das Zusatzheizgerät (20, 20a, 82, 83), welches als Brennstoffheizung mit einem Brenner- (20) und einem Wärmetauscherteil (20a) ausgebildet ist, direkt am Kühlmittel-/Luftkühler des Fahrzeuges anzuordnen bzw. in den Kühler zu integrieren. Diese Anordnung hat den Vorteil, daß der Brenner (20) mit seinen Brennstoff- (21) und Abgasleitungen (22) ausserhalb des Fahrgastraumes des Kraftfahrzeuges liegt und somit den Komfort und die Sicherheit im Fahrgastraum nicht beeinträchtigt. Darüber hinaus ist die strömungstechnische Einbindung des Zusatzheizgerätes in den Kühlmittelkreislauf einfacher und kostengünstiger.
(EN)
The invention relates to the arrangement of an additional heater for the coolant circuit in an internal combustion engine of a motor vehicle consisting of a coolant circuit including the coolant/air radiator and a heating circuit including the coolant/air heat exchanger for heating the passenger compartment. The technical problem in coolant circuits in modern, especially diesel, engines lies in the fact there is too little heat available for the heating system; thus additional heaters, e.g. using fuel, are in use. It is proposed that the additional heater using fuel and consisting of a burner and a heat exchanger be fitted directly on the coolant/air radiator of the vehicle or be integrated into the radiator. This arrangement has the advantage that the burner with its fuel and exhaust pipes is outside the passenger compartment and thus does not adversely affect comfort and safety therein. In addition, the inclusion of the additional heater in the flow of the coolant circuit is simpler and more economical.

L'invention concerne la configuration d'un chauffage supplémentaire (20, 20a, 82, 83) pour le circuit de refroidissement du moteur à combustion interne d'une automobile, qui comprend d'une part un circuit de refroidissement intégrant le refroidisseur à réfrigérant/à air (1, 70) et d'autre part un circuit de chauffage intégrant l'échangeur de chaleur à réfrigérant/à air, pour chauffer l'habitacle du véhicule. Le problème technique que posent les circuits de réfrigérant de moteurs modernes, notamment ceux des moteurs Diesel, réside entre autres dans le fait que la chaleur disponible pour le chauffage n'est pas suffisante, ce qui implique l'utilisation de dispositifs de chauffage additionnels, . Il est prévu de monter le dispositif de chauffage additionnel (20, 20a, 82, 83) qui se présente sous forme de chauffage à combustible, avec un brûleur (20) et un échangeur de chaleur (20a), directement sur le refroidisseur à réfrigérant/à air du véhicule, ou de l'intégrer dans le refroidisseur. Cette configuration présente l'avantage qu'avec ses conduites de combustible (21) et de gaz brûlé (22), le brûleur (20) se trouve en dehors de l'habitacle de l'automobile et n'en altère ainsi ni le confort ni la sécurité. En outre, en termes de technique de circulation, l'intégration du dispositif de chauffage additionnel dans le circuit de refroidissement est plus simple et plus économique.
