Claim 5:
6. An electronic component, comprising: a heat sink chassis enclosing heat generating electronic components; and a sunshield including: a main plate configured to be positioned to cover a side of the heat sink chassis; a housing including a heat sink chassis having cooling fins in proximity to the main plate; a back plate attachable to the electronic component, the back plate having two side tabs that are angled perpendicularly from the back plate and formed a gap with the tabs of the main plate to allow an airflow, wherein the back plate and the main plate, when attached to the electronic component, enclose the heat sink chassis and the plurality of tabs fixed to both sides of the heat sink chassis; a vent in the main plate allowing air flow through the main plate to the heat sink chassis; a shutter rotatable between an open position allowing air flow through the vent, and a closed position blocking air flow through the vent; and a biasing mechanism providing force to bias the shutter in the closed position, wherein the force is overcome by a predetermined level of external flow of air on the shutter to rotate the shutter to the open position; and wherein the biasing mechanism is an extension spring having a first end attached to the shutter and a second end attached to the main plate, wherein the shutter rotates on a hinge attached to a bottom edge of the vent.
