A fan assembly comprises a fan and a movable fan support. The fan has a motor and a fan blade drivable by the motor to move air in an airflow direction through an opening. The movable fan support is configured to movably support at least the fan. The fan support is mountable adjacent the opening on a first side and comprises extension members extendable from an operating position on the first side of the opening to an access position on a second side of the opening opposite the first side. In the access position, the extension members extend through the opening from the first side to the second side to support the motor and fan blade on the second of the opening for access.

A heat dissipating module including a casing, a fan, a plurality of blades and at least one locking element is provided. The casing has a first positioning side and a second positioning side opposite each other, and the casing includes a sliding recess located on the first positioning side. The fan is disposed in the casing. The blades respectively slide into the sliding recess and are positioned on the first positioning side and the second positioning side. The locking element passes through the sliding recess to limit the blades from moving out of the sliding recess.

A blower includes a first extension having a first discharge port formed in a first wall, a second extension having a second discharge port formed in a second wall facing and spaced apart from the first wall, a fan provided below the first and second extensions to guide air toward each of the first tower and the second tower, a first gate provided inside the first tower or protruding from the first wall, a second gate provided inside the second tower or protruding from the second wall, a first guide motor to change a position of the first gate, and a second guide motor to change a position of the second gate.

A blower may include a lower case having a suction port, a fan provided inside the lower case, an upper case provided above the lower case and having a space through which air blown from the fan flows, a discharge port penetrating the upper case and formed to be elongated, and a flow guide provided in the space and extending in a direction crossing a longitudinal direction of the discharge port.

A fan package of an information handling system includes a rear cooling fan, a front cooling fan, and a fan fin package. The rear cooling fan generates a first airflow. The front cooling fan generates a second airflow. The fan fin package is in physical communication with the rear cooling fan and the front cooling fan. The fan fin package includes multiple fins. Based on the first airflow and the second airflow, the fins rotate between a closed position and an open position. The fins are biased toward the closed position.

Systems for controlling louver positions are described herein. Such systems may include: a louver frame; a louver coupled to the louver frame via a rotation member and adapted to rotate at a louver side around an axis of rotation at the rotation member. In one embodiment, the louver includes a spring member engagement feature. The system also includes a spring member coupled to the louver frame and adapted to engage with the spring member engagement feature of the louver and apply a force to the louver when a forward airflow is applied to the louver in a forward airflow direction.

An air shutter comprises a holder, two compressible elastic members, a plurality of blades, and two cover plates. The holder comprises a central hub, an outer frame and a plurality of connecting pieces, and the outer frame has two annular grooves for receiving the two compressible elastic members. Each of the plurality of blades locates between two adjacent connecting pieces and one end is pivotally connected to the central hub and the other end is pivotally connected to the two compressible elastic members. In a windless state, a gap between two adjacent connecting pieces is closed by one of the blades, and when the windless state changes to a windy state, each blade is rotated by a wind force and area of the gap expands with the increase of the wind force. A radiating fan comprising the air shutter is also provided.
