Patent ID: 8873236

Claim:
An electronic device, comprising: a housing having a front and a back, and defining a receiving space; at least one heat-generating electronic component within the housing; and a fan module including at least one fan, the fan module being configured to direct cooling air over the at least one heat-generating electronic component; wherein the fan module is received within the receiving space of the housing and pivotably secured to the housing, and wherein the fan module is pivotable through 180° with respect to the housing, such that the cooling air can be directed in a front-to-back flow path or a back-to-front flow path through the housing; further comprising a rotation limiting mechanism that limits pivoting of the fan module with respect to the housing to 180°; wherein the rotation limiting mechanism comprises a first tab extending from the housing into the receiving space, a second tab extending from the housing into the receiving space, a first slot in the housing, and a second slot in the housing; and wherein when the fan module occupies a first orientation with respect to the housing in which the cooling air is directed in the front-to-back flow path, the first tab engages the first slot and the second tab is spaced from the second slot, and when the fan module occupies a second orientation with respect to the housing in which the cooling air is directed in the back-to-front flow path, the second tab engages the second slot and the first tab is spaced from the first slot.
