Heat Exchanger for a Condenser Unit which Eliminate Corner and Concentric Eddies for High Energy Efficiency

Abstract

A heat exchanger coil for a condenser unit which eliminate corner and concentric eddies for high energy efficiency includes a continuous curvature of an oval shape profile across a cross sectional view. The heat exchanger coil includes a circular section, a first planar section, a second planar section, and a coil opening as the first planar section and the second planar section are adjacently connected and tangentially positioned with the circular section. The configuration between the circular section, the first planar section, and the second planar section delineate the continuous curvature of an oval shape and the coil opening. The heat exchanger coil is internally placed within a cabinet assembly and connected with other associated components of an outdoor condensing unit or outdoor unit so that the heat exchanger coil is able to eliminate corner and concentric eddies that are generally present within rectangular and circular shaped heat exchangers.
