    Abstract: Apparatus for burn-in of printed circuit boards, particularly a hood with electrical connections, supporting the printed circuit boards or trays in superposed, staggered relationship, and angularly disposed from the horizontal, so that the semiconductors under test are exposed outwardly in ambient air and the power-dissipating load resistors are exposed inwardly. Heat shields below the individual boards reduces thermal interaction between trays. The heat from the load resistors rises vertically with entrained air through the top of the hood. Since the boards are staggered, and angularly disposed, fresh ambient air is enhancingly entrained at each level with the result that each board is thermally isolated from the other.

    Abstract: A transceiver handle heat dissipation airflow channeling system includes a transceiver device having a transceiver device chassis, at least one heat producing component that is housed in the transceiver device chassis, and a transceiver device handle that extends from the transceiver device chassis and that defines an airflow channel along its length. The transceiver device handle receives airflow at an airflow channel entrance defined by the transceiver device handle, directs the airflow through the airflow channel, and dissipates heat generated by the heat producing component(s) using the airflow directed through the airflow channel. For example, the airflow may be directed through the airflow channel and adjacent the heat producing component(s) in the transceiver device chassis, adjacent a heat dissipation device that is integrated with the transceiver device chassis, or adjacent a heat dissipation device that extends from a transceiver device port to which the transceiver device is connected.

    Abstract: A solid-state circuit breaker or a residential circuit breaker includes a base housing semiconductors, electronics and advanced software algorithms. The base has a first profile area. It further includes a ventilation system for cooling the solid-state circuit breaker. The ventilation system includes a main cover configured to be mounted on the base by covering the first profile area of the base. The main cover has a second profile area such that the second profile area has an array of holes built-in the main cover. The ventilation system further includes an outer cover configured to be mounted on the main cover by covering the second profile area of the main cover to form an assembly of multi-layered covers. The outer cover has a third profile area such that the third profile area has an array of ribs built-in the outer cover.

    Abstract: An electronic assembly includes a chassis having electronic module mounting positions. The electronic assembly also includes a respective electronic module received in each electronic module mounting position and having a module cooling gas passageway. Each electronic module has a module glide surface. The electronic assembly includes a respective sealing retainer coupled between the chassis and each electronic module. The sealing retainer has a cooling gas passageway aligned with a chassis cooling gas passageway and the module cooling gas passageway. The sealing retainer includes a retainer body having a retainer glide surface, and a gas sealing gasket carried by the retainer body. The module glide surface and the retainer glide surface have respective cooperating features so that the respective electronic module is maintained in spaced relation from the sealing gasket as the respective electronic module is slidably inserted into a seated position.
