Abstract
Apparatus and methods for cooling controller assemblies for electric utility vehicles are disclosed. Auxiliary implements powered by electric motors onboard a utility vehicle create airflow that is captured and directed to provide increased ambient airflow across heat sinks used to dissipate heat from heat generating components. Airflow across heated surfaces is further created by vehicle movement and vacuum pressure. Fins and other heat dissipating architecture are employed. Features of the cooling systems enable increased controller assembly functionality and/or decreased controller assembly package size.
