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.

Abstract: A rack of electronic equipment is convection cooled. Each unit in the rack has oblique cooling fins oriented in a same direction, to cause heated air to flow to a hot air pathway by a chimney effect, and to draw surrounding air along a cool air pathway to each of the units. A preferred unit has two housing sections thermally insulated from each other. Each housing section has its cooling fins on a side surface, some of the fins being aligned with fins on the other section, so that cooling air flows first over the cooler section and then over the hotter section. The cooler section is arranged for enhanced heat transfer from a heat sensitive element, and heat liberating units are heat sinked to the hotter section.

Abstract: Attachment of electronics to optical devices is made by supporting the optical devices on a heat spreader card and the electronics on a separate circuit card. Each card has at least a first major surface, with an optical transducing subassembly mounted perpendicularly from the major surface of the heat spreader card. Electronics, except for transducing elements, are placed on the circuit card. The only direct attachment between the circuit card and the heat spreader card is one or more flexible cables attached to the respective major surfaces. This arrangement mechanically isolates the circuit card from the heat spreader card. The flexible cables include electrical conductors held positionally in a polyimide matrix, which provides for thermal isolation of the heat spreader card and the circuit card.
