Abstract:
L'invention porte sur un conduit (1) d'air pour le refroidissement d'un accessoire de véhicule automobile, ledit conduit (1) comportant une entrée d'air (3), une sortie d'air (5) et un tronçon (7) reliant l'entrée à la sortie. Selon une caractéristique principale de l'invention le conduit (1) comporte un élément de filtration (9) de l'air destiné à refroidir l'accessoire.
Abstract:
The invention relates to a fan arrangement of a vehicle (2) in which the engine space (4) comprises inlets (10, 12) through which the fan arrangement (8) is adapted to drawing in ambient air in the form of cooling air flows (A, B), a cooling package (14) is situated in a first inlet (10) and the fan arrangement (8) comprises a first fan (16) adapted to drawing in (A) ambient air over the cooling package (14) to cool the latter, and to blowing out (C) warmed air from the engine space (4) to the surroundings (18) of the vehicle (2) via a first duct (20), the fan arrangement (8) further comprises a second fan (22) adapted to drawing in (B) ambient air over the engine (6) to cool the latter, and to blowing out warmed air (D) from the engine space (4) to the surroundings (18) of the vehicle (2) via a second duct (24), the first fan (16) is arranged on the same drive shaft (26) as the second fan (22), and a fan cowling (28) in the engine space (4) is adapted to separating the two air flows (A/C and B/D) from one another to prevent the air streams from affecting one another.
Abstract:
A cooling arrangement for a utility vehicle (310) is provided. A portion of the cool external ambient air, drawn into a radiator compartment (120) via an air intake unit (190), is supplied via a connecting duct (160) into an engine compartment (110) wherein the connecting duct bypasses a heat exchange unit (190). Advantageously, temperature sensitive components can be cooled by cool air which is not heated by the heat exchange unit (190).

Abstract:
A system for removing heat from the engine compartment (9) of a heavy duty truck (2). A first ventilating system (21) removes heat from the radiator (7). It is separated from a second ventilating system (51) that removes heat from the engine compartment (9). The first system takes heat from the radiator through a plenum (23) by centrifugal squirrel cage blowers (27), and is directs it out to ambient by ductwork. The second system draws ambient air generally from back to front of the engine compartment, preferably by cowl induction (53), without the use of ram air from the vicinity of the radiator. The exits of the two systems are into a slip stream of the heavy duty truck, and the exit of the second ventilating system is into a slip stream of the first, to scavenge air out of the engine compartment.
Abstract:
A heat exchange system for a power machine that has an engine compartment and a heat exchanger compartment is discussed. The heat exchange system includes a fan housing located between the heat exchanger compartment and the engine compartment. A fan assembly that includes an axial fan and a radial fan coupled to a center shaft having a longitudinal axis extending through the center shaft is positioned within the fan housing. The fan assembly is operably coupled to a fan drive mechanism that is configured to cause the fan assembly to rotate about the longitudinal axis in a first direction and a second direction. First and second control signals from a controller cause the drive mechanism to rotate in the first and second directions, respectively.
