The invention relates to a cooling system for a vehicle, the cooling system comprising a cooling fan comprising a ram air turbine disposed in an aperture of a fan shroud, the fan shroud comprising: an opening, a shutter mechanism movable between a closed position in which it closes the opening, and an open position in which it opens the opening so that a ram air flow can pass through the opening, wherein the fan shroud further comprises: a velocity sensor configured to measure ram air flow velocity, a temperature sensor configured to measure ram air flow temperature, and an actuator configured to move the shutter mechanism between the closed position and the open position based on measured ram air flow velocity and measured ram air flow temperature.

A vehicle includes a chassis, a cab coupled to the chassis, a prime mover coupled to the chassis and positioned at least one of beneath or behind the cab, and an accessory drive. The accessory drive includes an accessory and connecting shaft. The accessory is positioned forward of a front of the cab such that the accessory is spaced from the prime mover. The connecting shaft extends from the prime mover, past the front of the cab, and to the accessory. The connecting shaft is positioned to facilitate driving the accessory with the prime mover.

A rotary heat exchanger includes a hub configured to be rotatably driven by a shaft, a fan including a plurality of fan blades integrally coupled to the hub and extending radially outwardly therefrom, and a heat exchanger including a plurality of heat exchanger sections. The heat exchanger includes a plurality of cooling fins for receiving air from the fan. Each of the plurality of heat exchanger sections is located between two of the plurality of fan blades. The hub, the fan, and the heat exchanger are integrally formed as a single body by a three-dimensional printing process.

Disclosed are techniques for determining shroud size of a fan. The techniques receive by a computer processing system digital data of a three-dimensional representation of a shroud of an axial fan, partition the received data into a first partition corresponding to a shroud segment and a second partition corresponding to a fan segment. determine a shroud boundary ring for the shroud segment and a viewing angle of the shroud boundary ring, apply to an image of the first partition a beam shooting process to determine the shroud diameter, determine if there are pixels in the image, which have values that produce signals indicating that the pixels are coincident with portions of the shroud and when signal is detected, calculate the shroud diameter. One aspect includes using the determined should size opening for performing a flow simulation.

A cooling system includes a first cooler, a second cooler, a fan positioned to drive air through the first cooler and the second cooler, and a baffle system. The baffle system includes a baffle and an actuator. The baffle is positioned to facilitate selectively restricting airflow through at least a portion of the first cooler. The actuator is positioned to facilitate reconfiguring the baffle between (i) a first orientation where the baffle does not restrict the airflow through the portion of the first cooler and (ii) a second orientation where the baffle restricts the airflow through the portion of the first cooler, thereby diverting additional airflow through the second cooler.
