Problems solved by technology

However, the disadvantage is that a relatively high noise load will be induced by such an axial fan
[0009] In addition, conventional cooling devices have a relatively low cooling capacity during charging operation due to the lack of headwind, which often necessitates reducing the current intensity of the charging current after a certain charging time in order to avoid overheating and degradation of the battery
This disadvantageously increases the charging time of the motor vehicle

Embodiment Construction

[0057] exist figure 1An electrically-driven or electric-motor-driven motor vehicle 2 , in particular an electric vehicle, is shown in schematic and simplified illustrations. Motor vehicle 2 has an electric motor 4 as a drive system and a battery 6 as an electrical energy store for powering electric motor 4 . In order to cool the electric motor 4 and / or the battery 6 , the motor vehicle also has a cooling module or cooling device 8 as a cooler system or a cooler fan system. By means of the cooling device 8 , the oncoming wind is increased or an airflow is generated when the motor vehicle 2 is stationary. The oncoming wind or air flow is shown schematically in the figure with arrows.

[0058] In the following, the descriptions with regard to the spatial directions are also given in particular in the coordinate system of the motor vehicle (vehicle coordinate system) with reference to an exemplary installation situation between the radiator grille and the electric motor or batte...

Abstract

The invention relates to a cooling device (8) for cooling an electrically driven or driveable motor vehicle (2), having a first heat exchanger (10) and a second heat exchanger (12), having an air-guiding channel (14) which connects the first heat exchanger (10) and the second heat exchanger (12) and which has two diametrically oppositely situated passage openings (16, 18) which are reversibly closable by means of a first air guide (20) and by means of a second air guide (22), and having a cooler fan (24) which is arranged downstream of the second heat exchanger (12) in terms of flow.

Description

technical field [0001] The invention relates to a cooling device for cooling an electrically driven or electrically propellable motor vehicle. A motor vehicle is to be understood here in particular as an electric vehicle having an electric motor fed by a rechargeable battery, or a hybrid vehicle having an electric motor and an internal combustion engine. Background technique [0002] In particular, cooling systems for internal combustion engine motors of motor vehicles dissipate mainly that heat which is dissipated on the combustion chamber or cylinder walls. Internal combustion engine motors must be cooled as excessive temperatures can damage the motor. Modern internal combustion engine motors, especially four-stroke motors in motor vehicles, are, with a few exceptions, liquid-cooled, in which a mixture of water and antifreeze and corrosion inhibitors is usually used as coolant to keep the internal combustion engine motor cool. operating temperature and is used for the op...
