Abstract
Disclosed is a multiple heat exchanger system utilizing an inlet manifold to distribute the flow of thermoplastic material from an extruder to the inlet ends of each of the heat exchangers, and a discharge manifold to converge the flow of thermoplastic material from the discharge ends of each of the heat exchangers and to direct the flow to an extrusion die. The inlet and outlet manifolds include a main port in communication with a plurality of passageways within the manifold to allow flow between a main conduit in communication with the main port and a plurality of distribution conduits in communication with each of the heat exchangers. A flow control means positioned at each distribution port includes a sleeve, having a flow space therethrough, axially aligned within both the distribution port and distribution conduit. The distribution conduit includes a plurality of orifices about the circumference thereof in communication with the heat exchanger for the flow of thermoplastic material. The sleeve includes a plurality of flow control orifices about the circumference thereof for the flow of thermoplastic therethrough. Communication of varying portions of the sleeve flow orifices with the distribution orifices by axial movement of the sleeve regulates the flow of thermoplastic material into and out of the heat exchanger.
