| Abstract: | Heat sink consist of base and fin, the main parameters include the length of fin, the thickness of fin, the thickness of base and the width of base. Introduces the geometric structure of heat sink and researches on the geometric factors effecting the capability of heat sink. Investigate that thermal resistance can be lowered effectively by changing the geometric parameters of heat sink and get better effect. Provides the gist for the choice and the optimization of heat sink. |
