摘要:
A computer system that includes a chassis and a removable module configured to be housed inside the chassis. The chassis includes an interface plate incorporated therewith. The interface plate is perforated to allow air to flow through the interface plate and along peripheral cards attached to the interface plate. The air that flows along the peripheral cards then flows through perforations in a cover that is used to secure the peripheral cards into their associated card slots. The cover then directs the air into a primary air passage used to exhaust air pulled through the chassis.

A cooling system for a high-end server includes four hot-pluggable fans plugged into a fan control board. The fans are arranged in two groups, with each group having two fans, one behind the other. One of the groups of fans is used to cool the processor boards and the other group is used to cool the system I/O board slots. Under normal operation, only one fan from each group is active, while the other fan freewheels, providing redundancy. A fan control board delivers power to each of the fans and further provides a signal, responsive to temperature sensors, to each of the fans to control their speeds. Each of the fans provides a fan fault signal and a fan not present signal to the fan control board. The temperature sensors are placed proximate the processors and I/O components to monitor the operating temperatures thereof, and communicate the respective temperatures back to the fan control board, via I.sup.2 C bus. An operating system is utilized to drive the fan controller but can be overridden by the fan controller during critical conditions. An air ramp is positioned between the processors to help direct the flow of air generated by the fans onto some of the processors. Additionally, each of the fans are configured with a quick installment device to facilitate single-hand insertion and removal of the fans from the computer system.

A cooling fan comprising a housing that connects to a chassis that is operable to support an electronic component. An axial duct runs through the housing. A blade assembly is rotatably disposed within the duct and comprises a plurality of fan blades that extend radially from a hub to a fan diameter. The axial duct has a chord length at least equal to the fan diameter. A motor assembly is disposed within the axial duct and coupled to said blade assembly. The cooling fan provides a cooling capacity of at least 1.5 air horsepower per cubic inch volume of the cooling fan.

A computer system comprising a plurality of electronic components disposed within a chassis. The electronic components generate a cooling load of at least 50 CFM at 2 inches of water or greater. An air mover is disposed within said chassis and is operable to generate airflow of at least 50 CFM at 2 inches of water or greater. An air distribution system is coupled to the air mover and is operable to distribute the airflow to the plurality of electronic components.

A fan assembly that can be easily inserted into a mating slot includes: a housing surrounding and supporting a fan, a least one grill positioned so as to restrict access to the fan, a grip surface on the housing, a latch on the housing and configured to engage the mating slot; and, and an electrical connector mounted in the housing. The grip surface is formed on a separate piece from the housing and is affixed to the housing by an integrally formed fastening device and the assembly including the housing, grill, grip surface, latch and connector can be assembled by hand without the use of separate fasteners.
摘要:
A fan docking collar for sealing between a fan housing of a fan and an enclosure wall to improve fan performance by preventing flow recirculation. The docking collar includes a pliable body that defines an opening for air flow. The body has a seal for mating with the fan housing and a rim for sealing against the enclosure wall.
