Abstract
A heat exchanger is provided and includes a header, a tubular element and an expansion disc assembly. The expansion disc assembly includes a disc body and an actuator. The disc body includes two or more leaves fluidly interposed between the tubular element and the header and configured to cooperatively assume a closed condition by a first shuttering action at which the disc body exclusively inhibits a flow of the fluid, a fully open condition by a second shuttering action at which the disc body permits the flow of the fluid and partial open conditions between the closed and full open conditions by third shuttering actions at which the disc body exclusively inhibits a portion of the flow of the fluid. The actuator is controllable to cause the disc body to execute the first, second and third shuttering actions to assume the closed, fully open and partial open conditions.
