The semiconductor cooler is disposed on an inner surface of the protecting jacket body. The semiconductor cooler includes a Peltier element, a thermistor sensor, a PWM controller, and a switching element. The PWM controller is respectively coupled to the thermistor sensor and the switching element, and the switching element is coupled to the Peltier element. A circuit is connected by the switching element for making the semiconductor cooler work when a temperature of an electronic product is higher than a constant value. In distinct contrast, the circuit is disconnected by the switching element for stopping the semiconductor cooler working when the temperature of the electronic product is lower than the constant value. Therefore, the electronic product can maintain a longer working time, and conserving energy is achieved.

  • Publication number: 20120115059
    Abstract: An electricity output managing system for a fuel cell stack is disclosed. It includes a fuel cell stack, many power switches, an electricity adjusting module, multiple thermal sensors, and a controller. This electricity adjusting module is provided to combine the electricity outputs from these power switches into a single final output. The thermal sensors can detect the inner temperature values of the fuel cell units. The controller can receive the inner temperature values via these thermal sensors and calculate an average of all the inner temperature values which is a floating one. When one of the inner temperature values falls outside a normal range or one of the inner temperature value's variation rates exceeding a preset reference value, the controller turns off the power switch of the corresponding fuel cell unit and sends out a warning signal. So, it can effectuate the fuel cell management by monitoring the inner temperatures of these fuel cell units.
