Abstract

A heat-dissipating device ( 1 ) includes a casing ( 10 ) and a thermal insulation plate ( 20 ) provided within the casing ( 10 ). The thermal insulating plate ( 20 ) divides the interior of the casing ( 10 ) into a first accommodating space ( 101 ) and a second accommodating space ( 102 ). A hot air outlet ( 121 ) and a first air inlet ( 122 ) of the casing ( 10 ) are in communication with the first accommodating space ( 101 ). A cold air outlet ( 110 ) and a second air inlet ( 123 ) of the casing ( 10 ) are in communication with the second accommodating space ( 102 ). A thermoelectric cooling chip ( 30 ) is disposed in a through-hole ( 200 ) of the thermal insulation plate ( 20 ) and has a hot-end surface ( 31 ) facing the first accommodating space ( 101 ) and a cold-end surface ( 32 ) facing the second accommodating space ( 102 ). A heat-dissipating module ( 40 ) is received in the first accommodating space ( 101 ). A cold-airflow supplying module ( 50 ) is received in the second accommodating space ( 102 ). The heat generated by the hot-end surface ( 31 ) is dissipated to the hot air outlet ( 121 ) by the thermal conduction of the heat-dissipating module ( 40 ). The cold generated by the cold-end surface ( 32 ) is conducted and distributed uniformly by the cold-airflow supplying module ( 50 ) to the cold air outlet ( 110 ).
