Abstract
A passive cooled electronic chassis is used in a computer unit, or a display unit, or an actuator unit, or a like unit. The chassis overcomes the problem of the prior art chassis which has an active cooling system with parts that were difficult to operate, maintain and repair. The passive cooled electronic chassis includes an aluminum core member which has an electrical insulator sheet, a printed wiring board which bears against the electrical insulator sheet and which has a set of electrical components that are wired to the board, a housing which has a center wall that has recesses having potting material for receiving and embedding respective electrical components. The chassis provides a first heat flow path from such component through the printed circuit board and electrical insulator sheet and core member and center wall to exterior fins. The chassis also provides a second heat flow path from such component through the potting material and the center wall to the exterior fins. The housing has an end wall, which is integral with the end of the housing center wall, and which bears against the end of the core member, for the first heat flow path from the core member through the en…
