An electronic assembly includes one or more electronic components, and an enclosure in which the one or more electronic components are located. The enclosure includes a vertically top surface, a vertically bottom surface, and a plurality of side portions extending between the top surface and the bottom surface. A cooling arrangement for thermal management of the one or more electronic components includes a cooling airflow inlet to admit a cooling airflow into the enclosure, a cooling airflow outlet to exhaust the cooling airflow from the enclosure, and one or more cooling pathways between the cooling airflow inlet and the cooling airflow outlet. One or more removable covers are positioned over the cooling airflow inlet to allow for airflow ingress into the cooling airflow inlet, while preventing impingement of debris into the cooling airflow inlet.

An electronic module assembly includes a circuit card assembly (CCA) including heat generating electronic components. A connector is electrically connected to the heat generating electronic components. The connector is positioned at a connection end of the CCA. A heatsink is mounted to the CCA and is connected in thermal communication with the electronic components. A wedge feature is defined along a lateral edge of the heatsink relative to the connector.

Heat transfer interfaces for circuit card assembly (CCA) modules

An electronic module assembly includes a circuit card assembly (CCA) with heat generating electronic components. A connector is electrically connected to the heat generating electronic components, wherein the connector is positioned at a connection end of the CCA. A heatsink is mounted to the CCA, connected in thermal communication with the electronic components. An undulating channel feature is defined along a lateral edge of the heatsink relative to the connector. One or more channels of the undulating channel feature are aligned with an insertion axis defined by the connector.

An assembly includes a circuit card assembly (CCA) module including a CCA with heat generating electronic components and a connector electrically connected to the heat generating electronic components. A chassis including an electrical interface is included. The connector of the CCA module is electrically connected to the electrical interface. The chassis includes a removable cover. A heat transfer element is included between the cover of the chassis and an edge of the CCA module for heat sinking heat from the heat generating electronic components through the heat transfer element to the cover of the chassis.

An integrated adapter configured to hold two first circuit card assemblies in a larger second circuit card assembly space includes a thermally-conductive frame and two vertical thermally-conductive guide rails in the inboard region of the frame front. A channel is formed in each of the two guide rails, extending from the guide rail top to the guide rail bottom on the respective outboard side, thereby defining a front rail and a back rail, each configured to receive and support an edge of a first circuit card assembly, and the frame is configured to be attached to a second circuit card assembly, thereby forming an integrated adapter circuit card. Various circuit card sizes can be adapted for use, including supporting two 3U circuit cards in a 6U circuit card space. A method of making the integrated adapter is also disclosed.
