ABSTRACT:
An improved air flow enhancing stack for use with an air cooled heat exchanger designed for natural convection cooling. The stack includes a lower conical section having a larger end attached to the natural convection air exhaust from the heat exchanger and a smaller end positioned above the larger end. A central cylindrical section having a diameter equal to the diameter of the smaller end of the lower conical section is attached to the upper end of the lower conical section. An upper conical section, having a smaller end of diameter equal to the cylindrical section, is attached to the upper end of the cylindrical section and has its larger end positioned above its smaller end. A complete air enhancing stack provides improved convection cooling as compared to a conventional straight exhaust stack.
