Problems solved by technology

[0008] The first solution is to use a higher performance fan, which allows the fan to draw more power, making the engine itself use more fuel
While this approach works, there is no advantage
[0009] The second solution is to increase the heat exchange surface by increasing the size of the radiator, however this method cannot be applied to ordinary vehicles with compact dimensions
In the engine compartment of such vehicles, there is very little space for the radiator and in fact said main radiator is limited in size by the overall protrusion of the vehicle and cannot be enlarged

Embodiment Construction

[0018] figure 1 The cooling system 1 of the invention is shown mounted on an internal combustion engine 2, in particular a cooling system mounted on a common industrial vehicle engine.

[0019] The cooling system of the present invention includes a main radiator 10 placed at the front of the vehicle, before the engine. After said main radiator there is arranged a fan 11, which is adapted to direct a fresh air flow from the outside due to the forward movement of the vehicle, in the figure 1 Indicated by the "air flow" arrow diagram. The task of said fan 11 is therefore to draw air from the area in front of the main radiator 10 and direct it to the area occupied by the engine. The direction of the airflow generated by the fan 11 is consistent with the direction of the airflow due to the forward motion of the vehicle itself.

[0020] Thus, the fan is placed behind the main radiator 10 and encompasses substantially the entire surface of the radiator. In this way, the airflow g...

Abstract

The present invention relates to an engine cooling system (1), particularly, but not only, for an average industrial vehicle, characterized in that it comprises a second additional radiator (12) placed downstream the main radiator (10) with respect to the direction of the cooling air flow generated by the forward movement of the vehicle and / or by a fan (11) placed behind the main radiator (10). The cooling system according to the present invention allows to increase of about one third the overall heat exchange surface, that results in an improved efficiency of the system itself, that remains extremely simple, as there is a very restricted number of additional elements, easy to install and very small.

Description

technical field [0001] The present invention relates to an engine cooling system, and more particularly to an engine cooling system for general industrial vehicles, which cooling system has improved heat exchange efficiency, and to a vehicle incorporating the system. Background technique [0002] Radiators for air / water heat exchange are well known in the field of cooling systems for vehicle engines. The water or coolant flows through the engine cooling system and then to the radiator where it is hit by the fresh air flow for the required heat exchange. [0003] As the vehicle moves forward, the radiator is hit by the air flow at the front, in order to improve the heat exchange efficiency, a fan is usually placed behind the radiator, which is usually connected to a viscous static joint or an electric motor to ensure that it is used for Airflow required for heat exchange. [0004] In fact, the fan is mounted behind the radiator so as not to interfere with the fresh air flow...
