Título: (EN) HEAT-DISSIPATING DEVICE OF PORTABLE ELECTRONIC APPARATUS
Resumen: front page image
(EN)

A heat-dissipating device of a portable electronic apparatus includes a heat-conducting plate disposed on a heat-generating element. One end of a heat-conducting pipe is disposed on the heat-conducting plate, and the other end of the heat-conducting pipe is disposed on a surface of a power generator to form a high-temperature source. The opposite surface of the power generator is fixedly disposed on a heat-dissipating body to form a low-temperature source. A heat-dissipating fan is provided on one side of the heat-dissipating body. The positive and negative lines of the heat-dissipating fan are electrically connected to the positive and negative lines of the power generator. Via the above arrangement, after the heat-conducting plate conducts the heat source to the heat-conducting pipe to perform a heat exchange, the heat source is then conducted to the other end of the heat-conducting pipe, so that the surface of the power generator contacting the end of the heat-conducting pipe becomes a high-temperature source, while the other surface acts as a low-temperature source. Thus, the heat due to the temperature difference can be converted into electricity correspondingly, thereby providing the necessary power for the operation of the heat-dissipating fan. Therefore, a self-powered heat-dissipating device can be achieved.
