Problems solved by technology

However, these systems and devices tend to generate more heat that needs to be dissipated and thus an increase of the cooling system load.
However, the cooling fan is limited in its ability to cool the exhaust gas.
More power may be necessary to operate the cooling system, and fuel consumption may be increased.

Abstract

A cooling system for cooling a flow of fluid from a heat source includes a turbine configured to be fluidly connected to the heat source. The turbine is configured to receive the flow of fluid from the heat source. The cooling system also includes a fan configured to be driven by the turbine. The fan includes at least one channel for receiving the flow of fluid from the turbine.

Description

TECHNICAL FIELD[0001]The present disclosure relates generally to a cooling system, and more particularly, to a cooling system with an expansion driven fan.BACKGROUND[0002]Machines, such as on-highway vehicles and off-highway machines of a wide variety, may be powered by various types of engines, such as internal combustion engines. Internal combustion engines, the various systems associated with internal combustion engines in machines, and other components of a machine require a cooling system to dissipate heat. The size of a cooling system may vary based on a number of factors, including the amount of heat generated by the engine and its associated systems, and other machine components.[0003]The components of the cooling system may be located at the frontal area of the truck or other machine. For example, the cooling system may be designed to be accommodated at the frontal area of a machine. The cooling system may include components for cooling hydraulic oil, engine coolant, and en...
