Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Vorwärmung von Kühlmittel- und Ölkreisläufen, wobei jeweils ein Abschnitt der das Kühlmittel oder Öl führenden Leitungen durch eine Baugruppe geführt wird, der ein elektrisches Heizelement zugeordnet ist.The The invention relates to a device for preheating coolant and oil circuits, wherein each a section of the coolant or oil leading Leads are routed through an assembly that is an electrical Heating element is assigned.
Für verschiedenartige technische Anwendungen müssen in einem Kreislauf geführte flüssige Medien an Maschinen, Motoren, Getrieben und dergleichen erwärmt werden. Dies betrifft beispielsweise die Vorwärmung von Motor- und/oder Getriebeöl und/oder Kühlmittel an einer Brennkraftmaschine. Brennkraftmaschinen weisen nach einem Kaltstart zunächst einen verminderten Wirkungsgrad sowie gegebenenfalls eine erhöhte Schadstoffemission auf. Ursache hierfür ist neben anderen Aspekten die in diesem Betriebszustand hohe Viskosität der Öle, welche die Reibung zwischen den sich bewegenden ölgeschmierten Bauteilen noch nicht ausreichend vermindern können. Deshalb wird grundsätzlich eine schnelle Erwärmung des Kühlmittels und des Motor- bzw. Getriebeöls angestrebt. Hierbei ist es zumindest für extreme klimatische Einsatzbedingungen notwendig, eine entsprechende Erwärmung bereits vor dem Start der Brennkraftmaschine zu realisieren.For different types technical applications need guided in a cycle liquid media to be heated on machines, motors, gears and the like. This concerns, for example, the preheating of engine and / or transmission oil and / or coolant on an internal combustion engine. Internal combustion engines have a Cold start first a reduced efficiency and possibly an increased pollutant emission on. Cause for this Among other aspects is the high viscosity of the oils in this operating state the friction between the moving oil-lubricated components still can not reduce sufficiently. That's why basically a quick warming of the coolant and the engine or transmission oil sought. This is at least for extreme climatic conditions necessary, a corresponding warming already before the start to realize the internal combustion engine.
Für die Erwärmung des Kühlmittels werden Heizelemente bisher entweder in den Motorblock eingesetzt oder in vorhandene Schlauchleitungen integriert. Der Einbau in vorhandene Schlauchleitungen erfordert jedoch ein Gehäuse für das Heizelement, eine Abstützung für dieses Gehäuse sowie eine andere und aufwendigere Schlauchführung mit einem ersten Schlauch als Zulauf und einem zweiten Schlauch als Rücklauf. Unabhängig vom erheblichen Aufwand für das Heizgehäuse und die Verschlauchung sind solche Anordnungen ohnehin auf die Erwärmung des Kühlmittels begrenzt, eine Ölvorwärmung ist hingegen nicht vorgesehen. Ein weiterer Nachteil ist, dass eine derartige Ausführung mit starken Schwingungen von Brennkraftmaschine, Getriebe und Fahrzeug beaufschlagt wird.For the warming of the refrigerant Heater elements are previously used either in the engine block or integrated into existing hose lines. The installation in existing However, hoses require a housing for the heating element, a support for this casing and another and more expensive hose guide with a first hose as inlet and a second hose as return. Independent of considerable effort for the heater housing and the tubing are such arrangements anyway on the heating of the refrigerant limited, an oil preheating is however not provided. Another disadvantage is that one such embodiment with strong vibrations of internal combustion engine, transmission and vehicle is charged.

Somit wird eine einfache, kostengünstige und wenig Bauraum beanspruchende Ausführung erzielt.The inventive technical Solution enabled by a minor one Modification of an already available Assembly a combined preheating of coolant and oil circuits. By the structural integration of for a Heating necessary components in an existing heat exchanger is for the heating element no separate housing including the necessary for this Bracket and tubing needed. Thus, a simple, inexpensive and little space consuming execution achieved.
