Arcuate tubular evaporator heat exchanger

摘要

An indoor heat exchange unit and method of making same characterized by an arcuate coil shape heat exchange unit made by bending a planar heat exchange unit to fit within a limited space with an open inlet at one end and blocked at the other end so as to force air to flow past the coil and transfer heat through the fins and tubes of the coil in the process. Also disclosed are preferred embodiments in which an air circulation fan circulates air and where a thermostat controls the flow of heat exchange fluid through the coil as the air is passed through the arcuate coil to obtain a predetermined temperature, or the like, in the air.
