A cooling arrangement for cooling components of a heavy-duty electric or hybrid electric vehicle, the cooling arrangement comprising a fan, a mount, an axial flux electric motor, and a control unit arranged to control the cooling arrangement. The control unit is configured to obtain a predicted cooling requirement of the vehicle for a future time by obtaining information about a speed of the vehicle at a future time and using a heat estimation model to estimate an amount of heat generated at the future time based on the speed of the vehicle, and/or obtaining information about a characteristic of a path of the vehicle at the future time and using the heat estimation model to estimate the amount of heat generated at the future time based on the characteristic of the path of the vehicle.

A utility vehicle such as an agricultural tractor includes an engine, a heat exchanger, and a fan located under a hood. The hood is pivotable between a closed position and an open position. The fan is mounted to the hood such that, when in the closed position, the hood covers the engine and heat exchanger and the fan is positioned in an operable position to generate a cooling airstream through the heat exchanger. When the hood is in the open position, the fan is displaced from the operable position.

An air-cooled internal combustion engine including a crankshaft rotating about a crankshaft axis, a first cylinder having a first cylinder head, a second cylinder having a second cylinder head, and a blower assembly. The blower assembly includes a blower housing, a first fan, and a second fan. The first fan is positioned proximate the first cylinder and the second fan is positioned proximate the second cylinder.

A counter-rotating fan assembly includes an upstream fan that rotates in a first direction about a common axis and a downstream fan that rotates in a second, opposed direction about the common axis. The assembly has an upstream motor that drives the upstream fan, and an upstream motor support that supports the upstream motor. The assembly also has a downstream motor that drives the downstream fan, and a downstream motor support that supports the downstream motor. The upstream motor support is located upstream of the upstream fan, and the downstream motor support is located downstream of the downstream fan.

An automotive cooling fan assembly includes fan driven by a motor. The motor supported by a motor support structure of a shroud. The motor support structure includes a motor carrier and support arms extend radially outward from an outer surface of the motor carrier. The fan includes a central hub and blades that extend radially outward from the side of the hub. An axial operating gap is disposed between an end of the hub and the motor support structure. The motor support structure includes a protrusion that protrudes axially into the operating gap and serves to govern an extent of deflection of the fan during a water fording event.

A fan assembly including a first cooling fan arranged with respect to an air flow direction downstream of a heat exchanger and a second cooling fan. The first cooling fan is a radial fan that draws cooling air axially and expels the cooling air radially and the second cooling fan is an axial fan that draws cooling air axially and expels the cooling air axially. The axial fan is arranged downstream of the heat exchanger and laterally adjacent to the radial fan in a plane parallel to the rear side of the heat exchanger in a plane parallel to the front side of the heat exchanger.

The invention relates to a cooling module (22) for a motor vehicle (10) with an electric motor (12), comprising: —at least one heat exchanger (30.sub.1-30.sub.4); —at least one tangential-flow turbomachine (28) capable of creating an air flow that comes into contact with the plurality of heat exchangers (30.sub.1-30.sub.4); —a plurality of flaps (36P, 36A) movable between a first position, referred to as the position opening the cooling module (22), and a second position, referred to as the position closing the cooling module (22), said plurality of flaps (36P, 36A) occupying a portion of the cooling module not occupied by said at least one tangential-flow turbomachine (28).
