US Patent 11369036 Anti-reflow cover for a computer system component module

A component housing insertable in a chassis for a computing device blocking air flow when in a pulled out position is disclosed. The component housing has a front end and an opposite rear end. A pair of side walls are provided between the front end and the rear end. The side walls are slidably connected to the chassis to allow the component housing to be moved between an inserted position and the pulled-out position. A cover on the rear end has an open position allowing air flow through the rear end when the component housing is in the inserted position. The cover has a closed position blocking air flow through the aperture when the component housing is in the pulled out position.
