US Patent 7903405 Electronic device enclosures having improved ventilation to dissipate heat

Electronic device enclosures providing improved heat dissipation are described herein. An example enclosure for holding an electronic circuit board includes a housing having a first portion coupled to a second portion to form a cavity to hold the electronic circuit board. Each of the first and second portions comprises openings to direct convention airflow across opposing faces of the electronic circuit board at the same time. A baffle is coupled to the housing to substantially visually obscure the openings and to define a gap between the housing and the baffle to direct the convection airflow across the opposing faces of the electronic circuit board.
