1. A heat exchanger, the heat exchanger configured to divide fluid flow into two or more fluidically separated thermal circuits with each of the fluidically separated thermal circuits being configured to exchange heat with air through a single continuous face; wherein the two or more fluidically separated thermal circuits are located relative to one another in a configuration defined by one of the following:
i) in a stacked plate manifold that includes at least a first and second plate configured for inlet and outlet connections and to divide fluid flow into separate tubes by forming a wall between the thermal circuits, such that the fluid flows in the same direction through the separate tubes, with the exchange of heat with the air through the single continuous face;
ii) in a complex manifold comprising two or more distributors that separate fluid flow into each thermal circuit with the exchange of heat with the air through the single continuous face; and
iii) in a plurality of stacked evaporators; each evaporator comprising a plurality of coils with fins located there between, wherein the evaporators include at least one section of the coils in which fins are absent.
