ABSTRACT:
A cooling method that involves circulating a liquid coolant through the motor housings and mounting surfaces for electrical/electronic components, such as the electric motors and associated electronic drives, in electric plastic processing machines. Specifically, the motors are provided with a housing having an integral heat exchanger, such as stainless steel tubing cast into a cylindrical aluminum stator housing. The various electrical/electronic components are mounted to the surface of a plate type heat exchanger (chill plate) that is contained within the electrical cabinet for the primary electrical circuitry. In addition, the air within the electrical cabinet is continually circulated over the chill plate to provide a more uniform temperature distribution within the enclosure and minimize condensation on the surface of the plate. The heat generated by the motors and electronics is absorbed from the motor housings and chill plate by the circulating liquid and released through a heat exchanger.
