Abstract

The system has an electrically operated Peltier element (1) for cooling the fuel via a liquid heat exchanger. The resulting heat at the rear of the Peltier element is carried away via a second heat exchanger and a secondary cooling circuit. Alternatively, a cooling body can be applied directly to the rear of the Peltier element, or the Peltier element can be directly mounted on a radiator.

Description

Elektrisches Kühlsystem für Kraftstoffe von KraftfahrzeugenElectrical cooling system for automotive fuels

Stand der TechnikState of the art

Zurzeit werden Kraftstoffe unter Verwendung der vorhandenen Klimaanlage gekühlt. Dazu ist innerhalb der Klimaanlage ein Wärmetauscher vorgesehen, durch den der Kraftstoff fließt und dabei gekühlt wird.Currently, fuels are cooled using the existing air conditioning system. For this purpose, a heat exchanger is provided within the air conditioning system through which the fuel flows and is cooled in the process.

Problemproblem

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Kraftstoffkühlung zu schaffen, die unabhängig von einer vorhandenen Klimaanlage funktioniert.The invention specified in claim 1 is based on the problem of creating a fuel cooling system that functions independently of an existing air conditioning system.

LösungSolution

Dieses Problem wird mit den im Schutzanspruch 1.) aufgeführten Merkmalen gelöst.This problem is solved with the features listed in claim 1.).

Erreichte VorteileBenefits achieved

Mit der Erfindung wird erreicht, dass eine Kraftstoffkühlung auch ohne eingebaute Klimaanlage möglich ist. Eine vorhandene Klimaanlage muss nicht eingeschaltet sein (Kraftstoffeinsparung).The invention makes it possible to cool the fuel even without an air conditioning system installed. An existing air conditioning system does not have to be switched on (fuel saving).

Ausfuh rungsbeispielImplementation example

Ein Ausführungsbeispiel der Erfindung wird anhand der Figur 1.) erläutert. Die Wärmetauscher (2 und 3) bestehen aus massiven Metall mit eingearbeiteten Kanälen für die Flüssigkeit, die über jeweils zwei Anschlüsse zugeführt wird. Zwischen den beiden Wärmetauschern befindet sich das Peltierelement (1). Die Kaltseite des Peltierelement kühlt den Wärmetauscher (2) durch den der Kraftstoff vom Tank zum Motor fließt. Die Warmseite des Peltierelement wird vom Wärmetauscher (3) gekühlt. Die Wärme wird durch eine Pumpe (4) abtransportiert und durch einen Luftwasserkühler (5) gekühlt.An embodiment of the invention is explained using Figure 1.) The heat exchangers (2 and 3) are made of solid metal with incorporated channels for the liquid, which is supplied via two connections each. The Peltier element (1) is located between the two heat exchangers. The cold side of the Peltier element cools the heat exchanger (2) through which the fuel flows from the tank to the engine. The warm side of the Peltier element is cooled by the heat exchanger (3). The heat is transported away by a pump (4) and cooled by an air-water cooler (5).

Alternativ kann die Wärme von der Warmseite des Peltierelement mit einem Luftkühlkörper abgeführt werden. Der sekundäre Kühlkreislauf entfallt.Alternatively, the heat from the warm side of the Peltier element can be dissipated using an air heat sink. The secondary cooling circuit is no longer required.

Claims (2)

1. Elektrisches Kühlsystem für Kraftstoffe von Kraftfahrzeugen, dadurch gekennzeichnet, dass der Kraftstoff von einem elektrisch betrieben Peltierelement über einen Flüssigkeitswärmetauscher gekühlt wird. Die dabei entstehende Wärme auf der Rückseite des Peltierelement wird über einen zweiten Wärmetauscher und über einen Sekundärkühlkreislauf abgeführt. Der Sekundärkühlkreis besteht aus Wärmetauscher, Pumpe und einem Luft- /Wasserkühler.
Alternativ kann ein Kühlkörper direkt auf der Rückseite des Peltierelement angebracht werden, oder das Peltierelement direkt an einen Kühler montiert werden.
Die Temperaturregelung des Kraftstoffes kann über die Versorgungsspannung des Peltierelementes erfolgen. 1. Electrical cooling system for motor vehicle fuels, characterized in that the fuel is cooled by an electrically operated Peltier element via a liquid heat exchanger. The heat generated on the back of the Peltier element is dissipated via a second heat exchanger and a secondary cooling circuit. The secondary cooling circuit consists of a heat exchanger, pump and an air/water cooler.
Alternatively, a heat sink can be attached directly to the back of the Peltier element, or the Peltier element can be mounted directly to a cooler.
The temperature of the fuel can be controlled via the supply voltage of the Peltier element. 2. Kühlsystem nach Schutzanspruch 1, dadurch gekennzeichnet, dass die Kühlung über ein Peltierelement erfolgt. 2. Cooling system according to claim 1, characterized in that the cooling is carried out via a Peltier element.
