1. A heat dissipation device, comprising:
a package carrier, having a carrying surface and a disposing surface opposite to each other, wherein the disposing surface is divided into a first region and a second region surrounding the first region; a plurality of heat dissipating fins, disposed on the package carrier and located in the second region of the disposing surface, wherein the heat dissipating fins and the package carrier define an accommodating space, and an extending direction of the heat dissipating fins is perpendicular an extending direction of the package carrier; an atomizer, disposed on the heat dissipating fins and located in the accommodating space, the atomizer comprising an atomization unit, a liquid containing cavity and a fluid channel connected to the liquid containing cavity, wherein the liquid containing cavity, the heat dissipating fins and the package carrier define a fluid chamber, the atomization unit is connected to the liquid containing cavity, and a working fluid is stored in the liquid containing cavity; and a driving unit, electrically connected to the atomizer so that the working fluid is driven to the atomization unit and atomized into an atomization micro-mist, wherein the atomization micro-mist flows in the fluid chamber and flows back to the liquid containing cavity through the fluid channel. |
