Patent ID: 8289713

Claim:
A heat radiation structure of an electric apparatus that comprises an electric device including a heat source therein; a housing for the electric device; a casing disposed outside of the housing; and a circuit substrate received in the casing and having a plurality of electronic components mounted thereon, the heat radiation structure comprising a heat conductive member having an electrical insulating and heat conductive properties and flexibility, the heat conductive member disposed between the circuit substrate and the casing and closely attached to the casing, wherein: the plurality of electronic components are mounted on the circuit substrate; at least one of the electronic components is mounted on the circuit substrate via a lead terminal; and a heat-resistant protective sheet is attached to a surface of the heat conductive member that faces the circuit substrate, the heat-resistant protective sheet allowing heat conduction from the electronic components to the heat conductive member and not allowing the heat conductive member to contact the lead terminals to prevent the lead terminals from becoming corroded due to a corrosive material contained in the heat conductive member.
