Abstract
A heat sink is attached to fixing plates of a shield case. When a circuit board is covered by the shield case, the heat sink comes into contact with a circuit component mounted on the circuit board through a heat conduction sheet. Further, clearance holes, which are approximately closed by first heat dissipation plates, are formed to the shield case.
Claims9
A heat dissipation device for electronic equipment comprising:
- a circuit board on which a circuit component is mounted;
- a heat conduction sheet attached to the circuit component;
- a heat sink coming into contact with the heat conduction sheet and having first heat dissipation plates disposed in parallel to the circuit board;
