1. A heat transfer system for a vehicle, the system comprising:
a first duct on one side of the vehicle providing a passageway for air flowing through the first duct when the vehicle is moving, the first duct having an inlet located forward of a rear axle of the vehicle and an outlet located rearward of the rear axle;
a first surface heat exchanger positioned within an interior of the first duct;
a flow-through radiator located at a front of the vehicle and spaced apart from the first surface heat exchanger;
at least one vehicle component, wherein the at least one vehicle component includes an engine or motor in fluid communication with the flow-through radiator;
a heat transfer fluid reservoir in fluid communication with both the first surface heat exchanger and the flow-through radiator, wherein the heat transfer fluid reservoir stores fluid moving through the first surface heat exchanger, the at least one vehicle component, and the flow-through radiator;
a pump;
the first surface heat exchanger forming a heat transfer fluid flow circuit with the at least one vehicle component, the flow-through radiator, the heat transfer fluid reservoir, and the pump such that the fluid in the heat transfer fluid reservoir circulates through each of the first surface heat exchanger, the flow-through radiator, and the at least one vehicle component;
wherein the first surface heat exchanger forms an air flow pathway defined so that air flows through the inlet into the first duct, along an outer surface of the first surface heat exchanger within the interior of the first duct, and exits the first duct through the outlet.
 
9. The heat transfer system according to claim 1, wherein the first duct has an approximately ovoid or circular cross-sectional shape.
