Heat-dissipating device for supplying cold airflow

摘要

A heat-dissipating device (1) including a casing (10), a thermal insulation plate (20), a thermoelectric cooling chip (30), a heat-dissipating body (40), super heat pipes (52), a cooler (53), a first fan (54) and a second fan (60). The thermal insulation plate (20) divides the interior of the casing (10) into a hot air zone (ZH) and a cold air zone (ZC). The thermoelectric cooling chip (30) is disposed on the thermal insulation plate (20) with its hot-end surface (32) facing the hot air zone (ZH). The heat-dissipating body (40) is disposed in the hot air zone (ZH) to contact the hot-end surface (32). The super heat pipes (52) and the cooler (53) thermally contact a cold-end surface (31) of the thermoelectric cooling chip (30). Thus, the cold generated by the cold-end surface (31) can be rapidly and uniformly conducted to other places to form a cold airflow.
