Patent ID: 8593821

Claim:
A guillotine heat sink for an automotive audio system comprising: a heat sink structure defining opposed generally parallel guide surfaces; an audio system housing assembly including a case and a front closure member, said case having wall portions defining opposed cooperating guide slots within a cavity formed thereby, said guide slots configured for slidably receiving said heat sink; and at least one electrical assembly including a heat generating component disposed within said cavity in register with said guide slots wherein a leading contact surface of said heat sink abuts an exposed surface of said component to establish a thermally conductive path therebetween, wherein said housing assembly is formed of a composite of relatively rigid polymer material and electrically conductive material operable to shield said at least one electrical assembly from electrical anomalies including RFI (radio frequency interference), EMI (electromagnetic interference), BCI (bulk current injection), and ESD (electrostatic discharge), and wherein said electrically conductive material comprises a wire screen insert molded within said polymer material and extending substantially continuously along the wall portions of said case and said front closure member.
