Embodiment Construction

[0030] It should be noted that the drawings are given as examples and do not limit the invention. The drawings constitute schematic representations to aid in the understanding of the principles of the invention and are not necessarily to scale. In particular, the shown sizes and shapes of the various elements do not represent actual sizes and shapes, especially not the shape of the heat shield.

[0031] figure 1 and image 3 It has been described in the background section of this application.

[0032] by reference figure 2 and Figure 4 , the invention relates to a motorized fan assembly 1 for connection to a radiator 5 of a heat engine of a motor vehicle.

[0033] As is known, a motorized fan assembly 1 comprises a fan 2 arranged in an air duct 3 having an air guiding portion 3b. A heat shield 4 is provided eg in the area of ​​the air duct 3 protecting the area in the vicinity of a heat source which could damage the air duct 3 and at least partially melt the air duct. ...

Abstract

The invention relates to a fan unit (1) to be associated with a radiator (5) of a heat engine of a motor vehicle, the fan unit (1) comprising a fan (2) housed in a nozzle (3) comprising air-guiding portions (3b) and a thermal screen (4) for protecting an area of the nozzle (3), characterised in that the nozzle (3) does not have a guiding portion in the area protected by the thermal screen (4), the thermal screen (4) operating as a portion for guiding the air from the nozzle (3) to said area. The invention is applicable in the field of motor vehicles.

Description

technical field [0001] The invention relates to a motorized fan assembly comprising an air duct and a heat shield for connection to a radiator of a heat engine of a motor vehicle. Background technique [0002] As shown the motorized fan assembly according to the prior art figure 1 and image 3 As shown, this motorized fan assembly 1a includes a motorized fan 2 arranged in a funnel-shaped air duct 3a, and the motorized fan 2 is arranged in a narrowed opening or bayonet of the air duct 3a. [0003] In order to facilitate the heat exchange between the cooling liquid and the intake air, the motorized fan assembly 1a allows the intake of outside air at low vehicle speeds so that the outside air passes through the radiator described for cooling the cooling liquid of the heat engine 5. [0004] This design of the air duct 3a is advantageous, which ensures the guidance of the air through its parts 3b and 3c so that the air passes through the maximum area of ​​the exchanger and do...
