A fluid flow management system for enhancing cooling of a circuit pack. The system includes a bar extending transverse to the direction of fluid flow. The bar breaks up the otherwise laminar flow into a turbulent flow.

Fluid flow management system

An apparatus holds a feeler gage. The apparatus includes a shaft having an end to which the feeler gage is attached. A fixture aligns the shaft with an opening into which the feeler gage is inserted. The opening may be a gap of a connector. A portion of the shaft is a measuring section having a plurality of markers. The markers are stripes, grooves, or lands on a portion of the shaft. The fixture comprises a channel, sleeve or bearing that guides the shaft onto the fixture. The fixture includes a ridge for insertion of the fixture onto a track. The fixture may have an alignment arm that engages a side surface of the connector. The fixture has a latch that attaches the fixture to the track. The latch of the fixture comprises two substantially parallel elongate members separated by a distance approximately equal to a width of the track. The feeler gage may be attached to the shaft by a clamp that allows any of a plurality of feeler gages to be detachably mounted, the plurality of feeler gages including gages having respectively different shapes and sizes. Alternatively, the assembly may include a plurality of shafts, each shaft attached to a respective feeler gage having a respectively different dimension, such that only one of the plurality of shafts is received by the track at any one time.

A device for housing electronic components that produce heat and must be cooled. The device includes a housing having at least one vertical wall that has an interior surface and a corresponding exterior surface. Rows of vains are disposed on the interior surface of the wall. Each row of vains contains a plurality of parallel vains having the same general dimensions. Adjacent rows of vains are not aligned. As a result, the vains on one internal row do not lay in the same line as vains from adjacent internal rows. External vains are disposed on the exterior surface of the wall, opposite the internal vains. The external vains correspond in position and number with the internal vains. Heat absorbed by the internal vains is transferred to the external vains by conduction, wherein the external vains dissipate the absorbed heat to the surrounding environment with an efficiency that is made possible by the configuration of the vains.
