摘要： A heater-cooler system for a barrel of an extruder is disclosed. The system includes a heater adapted to be in thermal communication with at least a portion of a barrel of an extruder. The system further includes a shroud assembly that defines a cavity. The shroud assembly encloses the heater. The shroud assembly has an intake port and an exhaust port. A valve is in fluid communication with the exhaust port. The valve is moveable between an open position and a closed position. When the valve is in the closed position the exhaust port is substantially sealed. When the valve is moved between the closed position and the open position or is in the open position the cavity is in fluid communication an area outside of the cavity through the exhaust port.
