Abstract: An air duct includes a base and a latching portion extending from the base. The base includes a resilient portion and two blocking plates. The latching portion is configured to receive a fan. The resilient portion is elastic deformable to fasten the base to the fan. The latching portion defines a ventilation hole for air flowing through in a first direction. The two blocking plates are configured to prevent the air from flowing back to the ventilation hole in a second direction opposite to the first direction. A cooling module with the air duct and an electronic device with the air duct are further disclosed.

Abstract: An electronic device enclosure includes a side plate and a strengthening plate. The side plate includes a main body, a first mounting flange extending from a first edge of the main body, and a second mounting flange extending from a second edge of the main body. The first mounting flange defines a first clipping hole, and the second mounting flange defines a second clipping hole. The strengthening plate includes a first securing flange and a second securing flange. The first securing flange includes a first clamping portion. The second securing flange includes a second clamping portion. The strengthening plate is moveable in a first direction that is substantially perpendicular to the main body, to engage the first clamping in the first clipping hole; and the strengthening plate is rotatable about an axis, to engage the second clamping portion in the second clipping hole.
