The present invention provides, for use in a chassis configured to alternatively house first or second planar boards hating different thicknesses and daughter board side surfaces, a universal planar mount for supporting the planar board within the chassis. The universal planar may consist of a planar support coupled to a wall of the chassis that has first and second shoulders, preferably more than two, associated therewith that may be stair-stepped with respect to each other. The planar support may consist of a plurality of planar supports. In another aspect, the shoulders are formed in opposite side edges of the support walls. The first shoulder is engagable with the first planar board to mount the daughter board side surface of the first planar board a predetermined distance from the wall. Alternatively, the second shoulder is engagable with the second planar board to mount the daughter board side surface of the second planar board the same predetermined distance from the wall, thereby allowing either of the first or second planar boards to be used in the same chassis without modification to the chassis or accessory parts, such as the daughter boards.

Planar mounts capable of mounting planars of varying thickness

A computer chassis has a cotton side wall upon which a two-section support plate structure is mounted. Each of the two support plate sections has, along a side edge periphery thereof, an upturned TEM shielding lip portion. The plate sections are supportingly securable to the underside of a printed circuit board, such as the computer motherboard, and are slidably adjustable relative to the underlying bottom chassis side wall to selectively adjust the overall size of the support plate structure so that different sizes of printed circuit boards may be alternatively secured thereto while maintaining proper spacing between the TEM shielding lip portions and adjacent side edge portions of the supported circuit board.

Computer chassis having a size-adjustable, TEM-shielded circuit board

The present invention provides a shroud for cooling a heatsink that is associated with a heat generating electrical component. Conventionally, the heatsink has a base portion with a first side and an oppositely disposed second side. The first side has cooling projections with outer ends that extend from the first side with the second side being attached to the heat generating electrical component. The shroud of the present invention comprises a wall that may be comprised of a thermoplastic or metallic material, The wall extends about and covers a portion of the cooling projections to form a passage for a flow of fluid about the cooling projections. The passage has a varying cross-sectional area to maximize the flow of the fluid about the cooling projections, to thereby enhance transfer of heat from the cooling projections to the fluid flowing through the passage. In one aspect, the varying cross-sectional area is formed by at least one of the walls surround the cooling projections having a concave shape projecting toward the cooling projections.
