Thermoelectrically cooled components for distributed electronics control system for gas turbine engines

摘要

A gas turbine engine control component includes at least one electronic device (48), electronics such as an integrated circuit (112) associated with the device (48), and a thermoelectric cooler (118) for cooling the electronics mounted in a compartment (116). The thermoelectric cooler (118) may be disposed in or on a wall (80) of the compartment (116) with a heat sink (82) connected to a hot side (84) of the thermoelectric cooler (118) and a cold side (86) of the thermoelectric cooler (118) exposed to an interior (88) of the compartment (116). Data about and/or operating instructions for the device may be stored in memory on the integrated circuit (112). The data may be calibration information for the device. A bus connecting means is connected to the integrated circuit for transferring operating instructions and/or data from the integrated circuit out and/or out of the component. A controller or control system incorporating these devices and components have the devices electronically connected to the integrated circuit.
