International Classification:

G06F 116

US Classification:

361726, 360137, 364 781, 3122231

Abstract:

A technique is provided for coupling and uncoupling modular devices with electronic and computing devices. A latch is coupled to a release member, which operates to release the latch from a mate latch by bending the release member to move the latch laterally away from the mate latch. The release member also may have grips for tool-lessly bending the release member to release the latch from the mate latch, and for removing the desired device. The technique also may embody a modular device having the latch and release member, or it may embody an overall system having the modular device disposed in a receptacle.

Abstract:

Reversible airflow in cooling systems of electronic devices is described. For example, an electronic device may include a reversible fan tray. The fan tray may include symmetric mounting features that allow the fan tray to be mounted in the electronic device in more than one orientation at the same location within the electronic device such that one or more fans in the fan tray either direct air into the electronic device or to pull air from electronic device. The fan tray may further include a symmetric arrangement of connectors that coincide with the symmetric arrangement of mounting features to allow the fan tray to be connected to a power source of the electronic device any of the more than one orientations. An arrangement of electronic devices including reversible fan trays may be configured so that inlet and outlet airflows are separated to increase cooling efficiency of the electronic devices.

Abstract:

A reversible fan tray device is provided for a power supply unit. The fan tray device includes a mounting panel to be removably mounted to the power supply, a fan unit secured to the mounting panel to provide airflow through the electronic device, and an interconnection board secured to the mounting panel to provide an electrical connection between the fan unit and the power supply unit. The mounting panel can be positioned in either of two orientations, the first orientation to draw external air into the power supply unit and the second orientation to force internal air out of the power supply unit. The interconnection board mates with a connector on the power supply unit when the fan tray cassette is in either of the two orientations. The interconnection board provides an airflow direction indication to the power supply unit for an existing orientation of the two orientations.
