Patent ID: 8069681

Claim:
A cross-flow heat exchanger comprising: an axial flow path extending through the heat exchanger from an inlet having a surface area to an outlet having a surface area; a transverse flow path oriented transversely to the axial flow path and extending through the heat exchanger from an inlet having a surface area to an outlet having a surface area, the transverse flow path being adjacent to and separate from the axial flow path; wherein the surface area of the inlet of the axial flow path is less than the surface area of the outlet of the axial flow path; and wherein the surface area of the inlet of the transverse flow path is less than the surface area of the outlet of the transverse flow path; an evaporator positioned adjacent to the outlet of the axial flow path; a condenser positioned adjacent the outlet of the transverse flow path; a fan moving air from the evaporator to the inlet of the transverse flow path; and a cross-sectional area of the heat exchanger that is a right trapezoid and is positioned such that the smallest angle of the right trapezoid is adjacent to both the evaporator and the condenser.
