Description
Die vorliegende Erfindung betrifft eine Heizeinrichtung gemäß dem Oberbegriff des Patentanspruches 1 sowie ein Fahrzeug gemäß dem Oberbegriff des Patentanspruches 2.The present invention relates to a heating device according to the preamble of claim 1 and a vehicle according to the preamble of
Eine entsprechende Heizeinrichtung bzw. ein entsprechendes Fahrzeug ist aus der
Heizeinrichtungen zur Vorwärmung von Verbrennungsmotoren sind seit langem bekannt. So können Standheizungen in der Regel nicht nur zur Vorwärmung des Fahrgastraums, sondern auch zur Vorwärmung des Verbrennungsmotors eingesetzt werden. Heizeinrichtungen zur Vorwärmung von Verbrennungsmotoren sind aber keinesfalls Standard. Dies liegt zum einen an den damit verbundenen Zusatzkosten. Zum anderen ist eine Vorwärmung des Verbrennungsmotors in warmen Ländern bzw. Regionen weniger geboten als dies bei Fahrzeugen der Fall ist, die in „Kaltländern” betrieben werden.Heaters for preheating internal combustion engines have long been known. As a rule, parking heaters can be used not only to preheat the passenger compartment, but also for preheating the engine. Heating devices for preheating internal combustion engines are by no means standard. This is due to the associated additional costs. On the other hand, preheating of the internal combustion engine in warm countries or regions is less than is the case with vehicles that are operated in "cold countries".
Aufgabe der Erfindung ist es, eine Heizeinrichtung zur Vorwärmung eines Verbrennungsmotors zu schaffen, die mit möglichst geringem Aufwand bei einem herkömmlichen Fahrzeug nachrüstbar ist.The object of the invention is to provide a heater for preheating an internal combustion engine, which can be retrofitted with the least possible effort in a conventional vehicle.
Diese Aufgabe wird durch die Merkmale des Patenanspruches 1 bzw. 2 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is achieved by the features of
Das Grundprinzip der Erfindung besteht in einer Heizeinrichtung, die dazu geeignet und vorgesehen ist, von außen an einen Kühlleitungsabschnitt, z. B. an einen Kühlmittelschlauch eines Kühlkreislaufs eines Verbrennungsmotors, montiert zu werden. Für die Installation der erfindungsgemäßen Heizeinrichtung braucht somit nicht in den bestehenden Kühlkreislauf eines Fahrzeugs „eingegriffen” werden. Vielmehr handelt es sich um eine technisch in einfacher Weise, d. h. mit geringem Montageaufwand nachrüstbare ”ad-on-Lösung.The basic principle of the invention consists in a heating device which is suitable and provided, from the outside to a cooling line section, for. B. to a coolant hose of a cooling circuit of an internal combustion engine to be mounted. For the installation of the heating device according to the invention thus does not need to be "intervened" in the existing cooling circuit of a vehicle. Rather, it is a technically simple, d. H. Can be retrofitted with low installation effort "ad-on solution.
Die Heizeinrichtung kann in der Form eines Schlauchs bzw. einer Manschette ausgebildet sein, welche den betreffenden Kühlmittelleitungsabschnitt von außen her eng anliegend umgreift. Zur Vereinfachung der Montage einer derartigen schlauch- bzw. manschettenartigen Heizeinrichtung kann diese „offen”, d. h. klammerartig bzw. in Längsrichtung „geschlitzt” sein, so dass sie sogar einfach von außen her auf den betreffenden Kühlmittelleitungsabschnitt ”aufgeclipst” werden kann, ohne dass der Kühlkreislauf geöffnet, d. h. ohne dass ein Kühlmittelschlauch abgezogen und Kühlmittel abgelassen werden muss.The heating device may be in the form of a hose or a sleeve which engages tightly around the relevant coolant line section from the outside. To simplify the assembly of such a hose or sleeve-like heater, this "open", d. H. be clip-like or "slotted" in the longitudinal direction, so that they can even be "clipped" from the outside on the relevant coolant line section without the cooling circuit is opened, d. H. without removing a coolant hose and draining the coolant.
Nach einer Weiterbildung der Erfindung wird die Heizeinrichtung mit Gleichstrom betrieben. Sie kann unmittelbar an das Bordnetz des Fahrzeugs angeschlossen sein.According to a development of the invention, the heating device is operated with direct current. It can be connected directly to the electrical system of the vehicle.
Alternativ oder ergänzend dazu kann auch ein Gleichrichter und eine elektrische Wechselstromschnittstelle vorgesehen sein, über die die Heizeinrichtung an ein stationäres Wechselstromnetz, z. B. an die Steckdose in der Garage, angeschlossen werden kann.Alternatively or additionally, a rectifier and an electrical AC interface can be provided, via which the heating device to a stationary AC power, z. B. to the socket in the garage, can be connected.
Um sicherzustellen, dass die von der Heizeinrichtung gelieferte Wärme in den Verbrennungsmotor gelangt und kritische Stellen im Motor möglichst gleichmäßig vorgewärmt werden, ist eine elektrische Wasserpumpe vorgesehen. Eine elektrisch angetriebene Wasserpumpe kann nämlich nicht nur bei laufendem Verbrennungsmotor, sondern auch bei stehendem Verbrennungsmotor und eingeschalteter Heizeinrichtung Kühlmittel im Kühlkreislauf umpumpen, wobei im ”Heizmodus” anstatt des Begriffs ”Kühlmittel” der dann zutreffendere Begriff ”Heizmedium” verwendet werden sollte.To ensure that the heat supplied by the heater gets into the engine and critical points in the engine are preheated as evenly as possible, an electric water pump is provided. An electrically driven water pump can circulate coolant in the cooling circuit, not only when the internal combustion engine is running, but also when the internal combustion engine and the heating device are switched on. In the "heating mode", then the more appropriate term "heating medium" should be used instead of the term "coolant".
Viele moderne Fahrzeuge, insbesondere Fahrzeuge mit Turboladern, weisen bereits heute zusätzlich zu einer mechanischen Wasserpumpe eine elektrische Kühlmittelpumpe auf. Bei Verbrennungsmotoren mit Turbolader sind derartige ”elektrische Zusatzwasserpumpen” Bestandteil der Turbolader-Lagerstuhlkühlung. Für die Vorwärmung des Verbrennungsmotors kann somit bei vielen Fahrzeugen auf eine bereits im Fahrzeug vorhandene elektrische Kühlmittelpumpe zurückgegriffen werden.Many modern vehicles, in particular vehicles with turbochargers, already have an electric coolant pump in addition to a mechanical water pump. In turbocharged internal combustion engines, such "auxiliary electric water pumps" are part of the turbocharger bearing block cooling. For the preheating of the internal combustion engine can thus be used in many vehicles on an already existing in the vehicle electric coolant pump.
Ein weiterer sich unmittelbar aus der Erfindung ergebender Vorteil ist darin zu sehen, dass mit einer derartigen Heizeinrichtung nicht nur der Verbrennungsmotor vorwärmbar ist, was dessen Verschleiß verringert, sondern dass darüber hinaus auch gleichzeitig ein Wärmeeintrag in den Heizungswärmetauscher des Fahrzeugs möglich ist, so dass bereits unmittelbar nach dem Start des Verbrennungsmotors Heizleistung zur Verfügung steht.Another advantage resulting directly from the invention is to be seen in that with such a heater not only the engine is preheated, which reduces its wear, but that also at the same time a heat input into the heater core of the vehicle is possible, so that already Heating power is available immediately after the start of the combustion engine.
Selbstverständlich kann vorgesehen sein, dass mittels eines entsprechenden Steuergeräts das Ein- und Ausschalten der Heizeinrichtung programmierbar ist. Beispielsweise kann vorgesehen sein, dass die Heizeinrichtung mittels einer Zeitschaltuhr zu einem vorprogrammierten Zeitpunkt eingeschaltet wird und dass sie nach einer bestimmten Vorwärmdauer und/oder bei Erreichen einer bestimmten Vorwärmtemperatur, die z. B. im Verbrennungsmotor oder an einer bestimmten Stelle des Kühlkreislaufs gemessen werden kann, wieder abgeschaltet wird. Ferner kann vorgesehen sein, dass die Heizeinrichtung über eine Fernbedienung ein- und ausschaltbar ist, was den Bedienkomfort weiter verbessert.Of course, it can be provided that by means of a corresponding control device, the switching on and off of the heater is programmable. For example, it can be provided that the heater is turned on by means of a timer at a pre-programmed time and that they after a certain preheating and / or upon reaching a certain preheating temperature, the z. B. in the internal combustion engine or at a certain point of the cooling circuit can be measured, is switched off again. Furthermore, it can be provided that the heating device can be switched on and off via a remote control, which further improves the ease of use.
