ABSTRACT:
An electronic assembly (1) includes a top cover (21), a bottom cover (22) and a thermal module (10). The thermal module includes a centrifugal blower (14) and a fin assembly (12). The blower includes a top lid (142) defining a first air inlet (146) therein, a bottom plate (147) defining a second air inlet (150) therein, and a sidewall (148). An air outlet (149) is defined in the blower in front of the sidewall. A first distance (H1) formed between the top cover and the top lid is greater than a second distance (H2) formed between the bottom cover and the bottom plate. A left edge (154) of the second air inlet adjacent to the air outlet offsets a distance from a corresponding left edge (155) of the first air inlet inwardly toward a rotation axis (A) of an impeller (143) of the blower.
