Abstract
A thermostatically controlled enclosure for a small computer device includes a housing and a control circuit connected to a temperature signal generator such as a transistor. A circulating fan controlled by the output of the control circuit is mounted to the housing. Also provided is an LED indicator or audible alarm responsive to an over temperature condition within the housing. The control circuit consists of six basic blocks: a temperature to voltage converter; a high current operational amplifier; a fan on/off control; an over temperature sensor network an oscillator; and an LED or alarm driver.
