Abstract
The invention relates to a cooling system for a motor vehicle comprising a radiator (1) through which a coolant for, in particular, cooling an engine (2) flows, and which is flowed through by a cooling air flow (7) that is influenced by a fan (4) according to the velocity of the motor vehicle. Said fan is situated between the radiator (1) and the engine (2). The projection of the fan surface toward the radiator surface is smaller than the radiator surface by a difference area, whereby this difference area of the cooler surface is covered by a fan cowl (25). In order to create cooling system that is improved with regard to aerodynamics, the fan cowl (25) is provided with at least one opening (27) on at least one side of the difference area.
Claims16
A cooling system for a motor vehicle, comprising:
- a radiator through which a coolant flows for cooling an engine, and through which flows a cooling air stream,
- a fan configured to be arranged between the radiator and the engine,
- a fan cowling configured to cover at least a portion of a surface of the radiator, wherein the fan cowling includes a first opening and at least a second opening,
- wherein the first opening is configured to direct at least a portion of the cooling air stream through the fan,
- wherein the second opening is arranged to a lateral side of the radiator and is configured to direct at least a portion of the cooling air stream in a lateral direction so that the portion of the cooling air stream flowing through the second opening does not pass through the fan,
- wherein the second opening is located between the fan cowling and the radiator.
A cooling system for a motor vehicle, comprising:
- a radiator through which a coolant flows for cooling an engine, and through which flows a cooling air stream,
- a fan configured to be arranged between the radiator and the engine,
- a fan cowling that extends to the radiator and is configured to cover at least a portion of a surface of the radiator, wherein the fan cowling includes a first opening and at least a second opening,
- wherein the first opening is configured to direct at least a portion of the cooling air stream through the fan,
- wherein the second opening includes a plurality of guide lamellas arranged essentially parallel to one another in the form of a guiding grill in the second opening,
- wherein the guide lamellas are fixed,
- wherein the second opening is configured to recirculate back to the radiator at least some of the portion of the cooling air stream that flows through the first opening and the fan.
