A high cycle and speed valve () includes a body (), a valve seat () fixed within the body, and a diaphragm () that moves between a closed position in which the diaphragm is forced against the valve seat, and an open position in which the diaphragm is released from the valve seat. The valve seat includes a static section () that is secured within the body, and a dynamic section () that is compressed by the diaphragm when the diaphragm is in the closed position. The static section includes a radially extending flange () that is received in a recess () formed in the body to secure the static section in the body. The valve includes a body cavity relief space () into which the dynamic section compresses in the closed position. The valve further includes a cap () that has a dry film lubricant layer () that serves as a dry lubricant between the cap and the diaphragm.

A card shelf fire suppression system includes a card shelf having a backplane and a plurality of slots. The slots are each configured to receive an electronic card adapted for engagement with the backplane. The system also includes an airflow path for providing airflow adjacent the electronic card for dissipating thermal energy generated by the electronic card. The system further includes a damper system disposed proximate the slots and operable to passively activate to substantially prevent airflow through the slots and adjacent the electronic card. The damper system includes a damper, a support, and a thermal fuse. In response to an elevated temperature condition, the thermal fuse deforms causing the damper to become unsupported by the support, thereby accommodating movement of the damper from an open position to a closed position to substantially prevent airflow to the electronic cards.

Card shelf fire suppression system and method

A passive cooling system for cooling an enclosure containing electronic components. A hollowed portion of the enclosure is formed as an integral heat pipe containing a working fluid. The hollowed portion has an evaporator section located at the top and a condenser section located at the bottom. The enclosure also has hollowed side walls which serve as passage ways for the working fluid to flow through in between the evaporator and condenser sections. Gravity and the pressure of evaporation force the working fluid down to the condenser section. A wick is provided for returning the working fluid to the evaporator section by capillary action. Additionally, an ultrasonic transducer driven by the heat rejected from the condenser section may be used to help return the working fluid to the evaporator section. Finally, a check valve may be employed before the evaporator section for the working fluid to flow through.

Integral heat pipe enclosure

An enclosure which acts as a heat sink for dissipating heat generated by electronic components within the housing. The outer surface of the enclosure includes numerous cooling fins, preferably on all six faces of the enclosure, to help dissipate heat. The fins are diagonally oriented, rather than vertical or horizontal, to permit them to be effective whether the unit is mounted horizontally or vertically. In addition to dissipating heat, the enclosure is rain tight, EMI-tight and ESD-tight. The inside major surfaces of the enclosure include a number of pins extending inwardly to help increase the surface area for heat transfer into the enclosure material. The pins extend deeply into the interior of the enclosure, and are made shorter only where necessary to avoid large components on the printed circuit card. The spaces between the pins allow convection of the heated air whether the enclosure is vertically or horizontally mounted. The fins and pins together maximize heat dissipation from the electronics within the enclosure regardless of whether the enclosure is vertically or horizontally mounted.
