An air-conditioning apparatus for an electric vehicle and a method of controlling the same, may include a heat exchanger performing heat exchange between a first fluid and a second fluid while the first fluid and the second fluid flow separately from each other therethrough; a heat source connected to the heat exchanger through a line through which the second fluid flows to allow the second fluid to circulate between the heat exchanger and the heat source, and heating or cooling the second fluid; a circulator imparting a circulation force to the second fluid such that the second fluid circulates between the heat exchanger and the heat source; and a controller determining a required flow rate of the second fluid by use of a flow rate of the first fluid flowing through the heat exchanger and controlling the circulator on the basis of the required flow rate of the second fluid.

An electric vehicle having a heat exchanger formed in an aerodynamic airfoil shape comprising one or more body panels disposed along an outer surface of the vehicle having one or more fluidic chambers or micro-channels. The heat exchanger is adapted to provide effective and highly efficient heat transfer, and also to provide substantially reduced or negligible contribution to the aerodynamic drag. The heat exchanger includes a supplemental heat exchange system wherein at least a portion of the heat exchange capacity is provided by an inner heat exchange surface of the heat exchanger exposed to an interstitial space within the vehicle. Airflow is forced, via a fan for example, from an aerodynamically-efficient inlet, over the inner heat exchange surface, and exhausted through an aerodynamically-efficient outlet, thereby providing a supplemental heat exchange system including substantially reduced or negligible contribution to the aerodynamic drag.
