Abstract
Abstract In a high-speed bus apparatus, a thermodetector having a Peltier device embedded in a casing of the apparatus senses a temperature around the casing and sends the resulting output thereof to a switch-equipped current detector. In response, the switch-equipped current detector compares the temperature around the casing with a predetermined reference temperature. Based on the result of comparison, the switch-equipped current detector causes a cooling fan to selectively turn on or turn off such that the temperature around the casing remains at the reference temperature. As a result, temperature around a device received in the casing and adaptive to a high-speed bus is maintained substantially at an optimal temperature for high-speed transmission over a bus.
