Problems solved by technology

[0013] Known automotive hoods do not allow adequate cooling when designing engines that are likely to generate more heat than today, since the service life of the hood and other non-heat-generating components in the engine compartment will decrease significantly with increasing engine temperature. free

Embodiment Construction

[0051] figure 1- image 3 , different embodiments of fins 12 of different geometries are disclosed, such as flat ( Figure 1a-Figure 1d ),bending( figure 2 ) or curved fins.

[0052] Figure 1a-Figure 1d An embodiment of a hood according to the invention is disclosed comprising flat fins.

[0053] Figure 1aA hood 10 comprising a body structure 11 is disclosed in . The peripheral shape of the hood disclosed in FIG. 1 is just one example of the shape of the hood according to the present invention. The bonnets according to the invention can have different shapes in different situations, each being optimally shaped to fit a different position within the engine of the car.

[0054] The body structure 11 comprises at least one section with cooling fins 12 distributed on the outer surface of the bonnet, which provides a cooling zone 13 ( Figure 1b shown). The body structure 11 and the heat sink 12 are made of any suitable material, preferably metal material, preferably magne...

Abstract

An automotive engine cover is provided that at least partly covers an automotive engine in an automotive engine compartment. The engine cover, includes, but is not limited to cooling fins that are made of a metallic or ceramic material. The automotive engine cover is provided with improved cooling effect as compared to known automotive engine covers. The improved cooling effect prolongs the life-time of the automotive engine cover. The improved cooling effect also help to increase the life-time of other components in the engine compartment, which otherwise may degrade, deform or even melt dueto heat transfer from heat-generating components in the engine. In turn, this paves the way for the design of engines which may generate even more heat than today.

Description

technical field [0001] The invention relates to a motor vehicle hood, such as a cover or housing, which at least partially covers a motor vehicle engine in the engine compartment of a motor vehicle. Background technique [0002] Automobile hoods are known to be used in automobile engine compartments for various reasons, such as to protect the components in the engine compartment from being exposed to dust, to reduce damage on components due to oil leakage in the engine, and to reduce damage from the engine For example, noise that may disturb passengers in the car. Furthermore, engine covers may be used for aesthetic reasons where it is recognized that a particular engine cover design may impart an aesthetic appearance to the engine and nacelle. [0003] When an automobile engine is running, such as when a passenger car or another motor vehicle is driving on the road, various heat-generating components within the engine generate heat. As heat builds it is transferred to oth...
