摘要:
An air mover comprising a motor and a plurality of fan blades coupled to the motor. The motor is operable to rotate the fan blades about a blade axis in order to generate an airflow. A housing is disposed about said fan blades and defines a free area through which the airflow can travel. A first end of the housing is proximate to said plurality of fan blades. A second end of the housing has a free area that is unevenly distributed about the blade axis.

An apparatus for separating and extracting printed circuit boards in a computer system. More specifically, a basket assembly is provided through which a number of printed circuit boards may be attached to a motherboard. A card divider and extractor assembly including a card divider and card extractor is coupled to the basket assembly between each of the printed circuit boards. The card dividers provide structural and electrical isolation between the printed circuit boards. The card extractors provide a mechanism whereby printed circuit boards can be easily removed from the system while the system is operational.

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.

A system and method for controlling cooling fans in a computing system using measured temperature and amperage load is disclosed. In one embodiment, a cooling fan control device (CFCD) includes a temperature sensing module for measuring an inside temperature of the computing system using a plurality of temperature sensors disposed within the computing system and for computing a temperature value during operation, a power measurement module for measuring amperage drawn by each of the plurality of cooling fans during operation, and a driving module coupled to the temperature sensing module and the power measurement module to adjust rotational speed of each of the plurality of cooling fans during operation to obtain a desired airflow across the inside of the computing system based on the computed temperature value, a desired temperature value, and a lookup table including temperature and amperage drawn versus airflow values associated with each cooling fan.
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.
摘要:
An electronic module enclosure has a frame with an airflow opening. A gate positioned within airflow opening pivots between open and closed positions, allowing a maximum and minimum amount of airflow, respectively, through the airflow opening.

A motor with improved bearing life has a shaft rotatably supported by a pair bearings. The motor further has a stator and a rotor, wherein one of the stator and the rotor is mounted to the shaft and the other of the stator and the rotor surrounds the shaft so that the stator and rotor can rotate with respect to one another. The motor has one or more features to protect at least one of the bearings from heat emitted by at least one of the stator and the rotor.
