Cooling Assembly for a Vehicle

ABSTRACT

The present solution relates to a cooling assembly for a vehicle arranged to enhance cooling efficiency of a power source of the vehicle in some operational conditions. The present solution further relates to a vehicle comprising a cooling assembly.

BACKGROUND

A vehicle comprises one or more power sources for propulsion of the vehicle, such as an electric propulsion system and/or an internal combustion engine. All these types of power sources generate heat during operation. In order to avoid overheating, this heat must be dissipated from the power source to the surroundings. Therefore, vehicles are usually provided with one or more radiators arranged to cool the power source.

It can be difficult to get sufficient cooling of the power source of a vehicle in case the ambient temperature is high. Insufficient cooling means that the operation of the vehicle in terms of topography and the like are limited and thereby not all markets can be offered the vehicle. Also, if the cooling air temperature is high as a result of high ambient temperatures, the cooling fan/s need to operate at high revolutions causing high fuel consumption and high noise levels.

TECHNICAL SOLUTION

Reference is made to the Fig. 1 below which schematically illustrates a top view of a vehicle 3, according to some embodiments of the present solution. According to the illustrated embodiments, the vehicle 3 comprises a power source 5 arranged to provide motive power to the vehicle 3. The power source 5 may comprise an internal combustion engine, an electric machine, or both. The vehicle 3 further comprises a radiator 13 arranged to cool the power source 5. The radiator 13 forms part of a cooling system 14 of the power source 5. The vehicle 3 further comprises an occupant compartment 9 configured to accommodate occupants. According to the illustrated embodiments, the vehicle 3 is a large sized vehicle 3 and the occupant compartment 9 of the vehicle 3 is configured to accommodate ten or more occupants.

The vehicle 3 comprises a cooling assembly 1, according to some embodiments of the present solution. The cooling assembly 1 comprises a cooling apparatus 7 arranged to cool the occupant compartment 9. The cooling apparatus 7 may comprise a refrigeration system operating in a refrigeration cycle so as to cool the occupant compartment 9. Moreover, according to the present disclosure, the cooling assembly 1 comprises a duct arrangement 11 configured to conduct air from the occupant compartment 9 to the radiator 13. In this manner, the cooling capacity of the power source 5 is increased in a simple and efficient manner. This because when driving in areas having high ambient temperatures, it is highly likely that the cooling apparatus 7 is used for cooling the air of the occupant compartment 9. As a result thereof, the temperature of the air in the occupant compartment 9 will be lower than the air outside of the vehicle 3. Thus, by conducting air from...
