Abstract: A frame having a perimeter defines a planar opening. A set of louvers may span from a first edge of the opening to a second edge of the opening. Each louver may be capable of rotating between a closed position and an open position. A set of physical obstructions may prevent the louvers from rotating beyond the open position. Each louver may be offset from the planar opening by a first acute angle when in a closed position, and by a second, larger, acute angle when in the open position. A flow of air in a first direction through the opening may rotate the set of louvers to the closed position. A flow air in the opposite direction through the opening may rotate the set of louvers to the open position such that the flow of air in the opposite direction moves freely through the opening.

The latch may be disengaged from the cam by applying a disengagement motion to the cam and allow the latch to move relative to the chassis body and disengage from the enclosure. In this manner, the modular element is efficiently secured and removed from the enclosure with minimum obstruction to airflow to the electronic components.

The door resides at an air inlet or outlet side of an electronics rack, and includes an air-to-coolant heat exchanger with a heat exchanger core. The core includes a first coolant channel coupled to a coolant inlet manifold downstream from a second coolant channel, and the first channel has a shorter channel length than the second channel.
