Diffusive cooling device
A diffusive cooling device includes a plate body, on which a cavity recessed outwardly is formed and an opening is arranged; a web plate jointed at the upper side of the plate body correspondingly; a plurality of passing openings arranged on the web plate to act as air passages; a scroll fan arranged between the plate body and the web plate in corresponding to the opening; a shell body connected to the bottom of the plate body and jointed to the web plate correspondingly to enclose and prop up the plate body therein; and, an air inlet arranged at the front side of the shell body, through which an ambient air is flowed into the shell body by the extracting and thrusting forces of the fan. During operation, airflow is generated along the cavity and extended to corresponding area of web plate to diffusively pass through the plural passing openings to achieve a cooling objective.
