Technical Field

The invention relates to a motor vehicle according to the preamble of claim 1.

Background

In the tempering of the passenger compartment of motor vehicles of the same type, hot air for heating is usually introduced into the foot region in a tendency manner, while cold air for cooling is preferably introduced from a higher-positioned outflow into the head region or the upper limb region. In this case, a large part of the cold air is supplied for the rear via the intermediate outflow of the motor vehicle dashboard.

However, the air circulation in a motor vehicle is disturbed between the seats of the first row (front region) and the seats of the second row (rear region) by mountings in the vehicle, for example displays or partition walls. If such a partition wall or a larger display is suspended in the ceiling region, the cooling power in the rear is significantly reduced. Furthermore, the air flowing in from the front impinges on the partition wall or the display and falls there, and leads to a ventilation phenomenon in the head/back region of the first row of seats.

Disclosure of Invention

The object of the invention is therefore to create a motor vehicle of the type specified in the preamble of claim 1, which allows increased cooling power in the rear and at the same time preferably reduces the ventilation phenomena in the first row of seats or in the front region.

This object is achieved by the features of claim 1.

In particular, the motor vehicle according to the invention has a vehicle body with a front region (front seats) and a rear region (rear seats). A mounting member is disposed between the front region and the rear region. In order to avoid the problems mentioned at the outset with regard to reduced cooling capacity in the rear region and ventilation phenomena in the front region, according to the invention a fan is installed in the mounting part, which may be, for example, a display or a partition wall, which draws off the air quantity accumulated on the front side of the mounting part and guides it via one or more channels onto the rear side of the mounting part and thus cools the rear.

Although it is known from DE 19814581 a1 to provide a separate heat exchanger, optionally together with an associated fan, in each partial region, in particular also in the rear region, of the motor vehicle body, this publication neither describes the problem on which the invention is based nor does it describe a solution to this problem which is achieved by a fan which, as described above, draws off the air quantity which accumulates on the front side of the mounting part and guides it to the rear side of the mounting part.

The dependent claims contain advantageous further developments of the invention.

According to the invention, the fan can be designed as a centrifugal fan.

In a particularly preferred embodiment, the centrifugal fan is designed as a single-sided suction fan, and in a further preferred embodiment the centrifugal fan can be designed as a straight-flow fan.

According to the invention, it is possible for the fan to be integrated in the mounting part, i.e. to be mounted therein; or if it is for design-or space-related reasons possible that the ventilator is mounted on the mounting part.

Furthermore, it is possible according to the invention to provide a flow channel or a plurality of flow channels, depending on how large the mounting parts are and into which parts of the rear region cooling air or heating air is to be introduced.

If the mounting component is designed as an electronic component to be cooled or if the mounting component has such an electronic component to be cooled, it is also possible to use a part of the sucked air as cooling air for the electronic component. For this purpose, suction openings can be provided on the rear side of the electronic component or of the housing of the mounting component, via which suction openings cooling air can be supplied to the electronic component.

Drawings

Further details, features and advantages of the invention result from the following description of an embodiment according to the drawings. Here:

FIG. 1 shows a schematic, greatly simplified schematic diagram of a motor vehicle according to the invention, and

fig. 2 to 4 show examples of passive or active display circulation.

Detailed Description

Fig. 1 shows a motor vehicle 1 according to the invention, which is provided with a vehicle body 2, in a schematically greatly simplified illustration. A front region 3 is provided in the vehicle body 2, which front region corresponds to a front seat. Furthermore, the body 2 has a rear region 4 which corresponds to a rear seat, which is not shown in detail in fig. 1.

Between the front region 3 and the rear region 4, a mounting part 5 is schematically shown in a greatly simplified manner, which in the present case is a display suspended on a roof 8 of the vehicle body 2.

The mounting part 5 may be provided with a ventilator 6 which is in flow connection with one or more channels, which are indicated in fig. 1 by a single channel 7.

In this way, cooled air or heated air which accumulates on the mounting part 5 on its front side facing the front region 3 can be drawn off and conducted into the rear region 4 via the one or more cooling channels 7.

An example of passive mounting member circulation is shown in fig. 2 and 3, while fig. 4 illustrates active circulation.

In addition to the foregoing written disclosure of the invention, reference is hereby explicitly made to the diagrammatic illustration thereof in figures 1 to 4.
