Abstract: The instant invention pertains to a road vehicle's axial flow cooling fan which normally draws cooling air from in front of the vehicle and blows it into the engine bay. The instant invention includes a control circuit for the fan motor that provides variable speed and bi-directional, or reverse and normal, fan operation. Reverse fan operation blows air from the engine bay through the radiator and out the front of the vehicle, and normal fan operation blows into the engine bay. Two input sensors feed the control circuit, one for road speed of the vehicle and other for engine temperature. When the engine is below its operating temperature and the vehicle is moving, the fan is made to blows in reverse at a speed proportional to road speed so as to block cold ram air from entering and blasting onto a warming engine. This speeds engine warm-up to reduce emissions, improve fuel economy, and speed windshield defogging.

Separate spaced side tank portions are formed that are joined together with a front end tank to form a central opening with upper and lower ends. The opening is closed with a top plate that defines a plenum chamber and a lower fan support plate that forms a fan chamber in the central opening. A fan in the fan chamber creates an airflow from the exterior through the plenum chamber and out lateral ducts formed in the side tank portions.

Abstract: A carrier (1) is secured to a vehicle front end portion via a bracket (4) secured to side members (2) and a bumper reinforcement (3). The connecting portions of the carrier (1) to the bracket (4) are deviated from the side members (2) when viewed from the front side of a vehicle. The bracket (4) is provided with a reinforcing member portion (4a) to connect the left and right side members (2). Accordingly, the action of a large impact force on the carrier (1) can be prevented because only a collision force from the bumper reinforcement (3) acts on the carrier (1) and no reaction force, from the side members, acts on the carrier, when a collision occurs. Therefore, the carrier (1) can be prevented from being broken when a light collision occurs because the attaching portions of the carrier (1) are seldom broken. The rigidity of a vehicle body can be increased by the reinforcing member portion (4a), and the necessary rigidity of the carrier (1) can be reduced. Thus, the weight of the carrier (1) can be reduced.

Abstract: An engine cooling module 10 which includes a shroud 12, a heat exchanger 18, a fan 14, a motor 13 for driving fan 14, and a plurality of air dams 1. Shroud 12, circumscribing the fan, has a main opening to allow air to pass through the fan to or from a heat exchanger 18. Fan 14 is associated with the shroud 12 to be adjacent to the fan opening to permit air moved by the fan to pass through the heat exchanger. Air dams 1 allow air to flow more easily in one direction than the opposite direction. In the fan flow direction, air dams 1 provide relatively little resistance to the flow. In the direction opposite to fan flow direction, air dams 1 provide more resistance than as compared to the resistance when air flows in the fan flow direction. Under ram air conditions (e.g., when the vehicle is moving), the use of air dams can reduce the load on the fan's motor by cooling properties of ram air, while reducing recirculation, thereby increasing efficiency.

Abstract: The addition of emission control devices to engines of work machines has increased the cooling demands placed on the engine cooling system. This increased cooling demand can lead to the use of larger engine heat exchangers, thus requiring larger engine enclosures that may restrict the visibility of the machine operator.

An engine heat exchanger is mounted to a machine frame rearward of an operator cab and positioned so that an upper edge of the heat exchanger cooling core extends along a line that intersects the longitudinal axis of the machine frame at an angle other than 90°. This arrangement permits the use of a larger heat exchanger without substantially obstructing the view of the machine operator.
