ABSTRACT:
A housing for an electronic circuit board includes a housing member and identical top and bottom cover members. Inwardly extending ribs located on the interior sidewalls of the housing member align and support the circuit board, and provide convection cooling channels which allow air to circulate freely over the circuit board. The housing member is preferably an integrally cast member formed with integral fin surfaces which dissipate heat for the protection of temperature sensitive electronic components within the housing.
