Abstract
An electronic appliance includes a heat-dissipating apparatus mounted in a housing that has a heat-producing electronic component disposed therein. The heat-dissipating apparatus includes a thermoelectric semiconductor module operable so as to provide low and high temperature surfaces, a cool air blower unit including a first fan casing in heat-conductive contact with the low temperature surface, and a hot air exhaust unit including a second fan casing in heat-conductive contact with the high temperature surface. The cool air blower unit further includes a first fan mounted in the first fan casing and operable so as to draw air into the first fan casing via a first air inlet and so as to blow the air out of the first fan casing via a first air outlet. The air passing from the first air inlet to the first air outlet is cooled when the thermoelectric semiconductor module is operated due to contact between the first fan casing and the low temperature surface. The hot air exhaust unit further includes a second fan mounted in the second fan casing and operable so as to draw air into the second fan casing via a second air inlet and so as to blow the air out of the second fan casing and t…
