A fan module containing a fan is used to cool a computing device or system. The fan module is mounted within a chassis, and contains a housing, a locking body, and lever. The housing of the fan module contains a housing, a locking body, and lever. The housing of the fan module defines a hollow interior that houses the fan. The locking body is coupled to the housing and is moveable between a locked position and an unlocked position. When in the locked position, the locking body extends through a locking aperture in the floor of the chassis. When in the unlocked position, the locking body rises above the locking aperture in the floor of the chassis. Moving the lever from the first position to the second position causes the locking body to move from the locked position to the unlocked position.

A modular system for a small-scale data center may be manufactured offsite and assembled within the housing of a wind turbine. The modular configuration allows for more rapid design, construction, and operation of the system for turnkey projects. The modular system employs optimized features to take advantage of wind turbine power and is structured for effective cooling. The modular data center system also has connectivity for maintenance oversight, remote management, communication between multiple modular wind turbine and data center systems, and power backup to ensure consistent operation as needed.

A data center cooling system includes an air handler, a blower coupled to the air handler, and a thermal-polarization pipe coupled to the blower. The blower is configured to supply air through the thermal-polarization pipe. The system also includes at least one pressure box coupled to the thermal-polarization pipe, where the at least one pressure box is configured to house electronics. The thermal-polarization pipe includes an inner tube, an outer tube surrounding the inner tube and forming an annular cavity between the inner and outer tubes, and a thermal-polarization membrane carried by an outer surface of the inner tube.

A method for converting a computing device from a first configuration to a second configuration is provided. A power supply unit of the computing device is moved from a first location at a second end of the computing device to a second location at a first end of the computing device. The power supply unit is rotated such that a power interface of the power supply unit is visible from the first end of the computing device. A set of fans of the computing device is rotated such that airflow direction of the set of fans matches an airflow direction of the power supply unit at the second location. Converting the computing device from the first configuration to the second configuration can allow communication ports to be accessed from a front end or from a rear end of the computing device.

A battery system can provide backup power for information technology (IT) equipment. In response to a lithium ion based battery being inactive (not charging or discharging), a temperature of the battery can be maintained at or below an optimal storage temperature of the battery, using a primary cooling system. If the primary cooling system is insufficient, the temperature can be maintained at or below the optimal storage temperature with a secondary cooling system that runs in addition to the primary system. The optimal storage temperature of the battery is determined based on an effort to cool the battery and a degradation of the battery.

A computer system includes a chassis, one or more hard disk drives coupled to the chassis, and one or more air passages under at least one of the hard disk drives. The air passages include one or more air inlets and one or more air outlets. The inlets direct at least a portion of the air downwardly into the passages. The passages allow air to move from the air inlets to the air outlets.

One embodiment provides rotating shaft, including: a spindle comprising an internal first channel; a wheel casing operatively coupled to the spindle, wherein the wheel casing comprises an internal second channel; and a bearing housing the spindle, comprising a third channel located between the bearing and the spindle; wherein the first channel, the second channel, and the third channel are located to form an enclosed annular channel configured to hold a substance. Other aspects are described and claimed.

A fixing bracket includes a connecting plate, a top plate, and two side plates. The two side plates are parallel to each other and cooperatively define an accommodating space with the top plate and the connecting plate. The connecting plate, the top plate, and the two side plates are integrally formed. A cutout is defined in at least one of the connecting plate and the top plate for passing through a clamping spring.

A cooling system is disclosed for a server rack holding one or more servers. The cooling system includes a cooling module configured to condition coolant to provide cooling within the server rack. The cooling system further includes at least one evaporator configured to couple to an upstream side of the server rack, relative to airflow through the server rack, and cool the airflow flowing into the server rack with the coolant. The cooling system further includes at least one condenser configured to couple to a downstream side of the server rack, relative to the airflow through the server rack, and cool the coolant after the coolant passes through the at least one evaporator.
