Title:
HEAT SINK APPARATUS
Document Type and Number:
Japanese Patent JP2002305273
Kind Code:
A
Abstract:
To provide a heat sink apparatus that can reduce the discharge of radiation noise by decreasing antenna effects.
In the heat sink apparatus, plural heat dissipation fins 2 are erected on a base section 1, and the base section 1 is brought into contact with the heat sink surface of a high heat generating element for cooling the high heat generating element. In the heat dissipation fin 2, a high heat transfer dissipation fin 2A and a high resistance dissipation fin 2B are mixed. The high heat transfer radiation fin 2A is formed by a material, having proper heat transfer properties, and the high resistance dissipation fin 2B is formed by a metal material having high conductive resistance.
