Title:
プラスチック処理機械用の液体冷却装置
Document Type and Number:
Japanese Patent JP3987572
Kind Code:
B2
Abstract:
A cooling system which circulates a liquid coolant through motor housings and mounting surfaces for electrical/electronic components. This system is particularly cost effective where there are multiple electric motors and associated electronic drives, as 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 compartment for the primary electrical circuitry. In addition, the air within the electrical enclosure 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. Electrical resistors are cast into the chill plate so that the heat transfer from these components is optimized and space is saved by making this an integral construction.
