This report investigate the effect of different types of fins on the thermal performance heat sinks of notebook computers. The temperature distributions within the heat sink, the thermal resistance of the fin and the thermal resistance of the entire heat sink module is studied experimentally.
The experimental results show that:(1)Offset-strip fins type can reduce the thermal resistance since it can provide higher heat transfer coefficients.(2)Dimpled fins also can reduce the thermal resistance, but no as significant as that for offset-strip fins.(3)Tilted fins have better thermal performances when the tilted angle is 10o and 15o. For tilted angles between 20o ~ 45o, the thermal resistances become higher.(4)For mixed-type fins(by mixing different proportions of 10o and 15o tilted fins with 0o fins),the best proportion of titled fin 2/3
