US Patent 7397660 Method and apparatus for regulating airflow in a chassis

An airflow regulating apparatus includes a support frame for coupling to a chassis adjacent a heat producing component connector, the support frame defining a regulator channel, and also including an airflow regulator moveably coupled to the support frame and operable to be positioned in the regulator channel. A board including a heat producing component may be provided and the support frame coupled to the board, whereby the airflow regulator will move out of the regulator channel to allow airflow through the regulator channel and past the heat producing component. The heat producing component may then be removed, whereby the airflow regulator will move into the regulator channel to prevent airflow through the regulator channel.
