ABSTRACT:
A heat dissipation apparatus (100) includes a centrifugal blower (20) and a heat dissipater (10). The centrifugal blower includes a casing (22), a stator accommodated in the casing, and a rotor (24) rotatable disposed around the stator. The casing includes a base wall (224), a sidewall (226) surrounding the base wall and a cover (222) attached to the sidewall. The sidewall defines an air outlet (221) therein. An air channel (223) is formed between blades (242) of the rotor and an inner surface of the sidewall of the casing. The heat dissipater is made of porous material and disposed at the air outlet of the centrifugal blower. The heat dissipater has a tongue portion (12) extending into a part of the air channel.
