Abstract: The present invention is for a vacuum imaging drum with vacuum holes for maintaining a boundary layer in an image processing apparatus (10). The image processing apparatus (10) with a vacuum imaging drum (300) for holding thermal print media (32) and donor sheet material (36) in registration on the vacuum imaging drum (300). A printhead (500) moves along a line parallel to the longitudinal axis (X) of the vacuum imaging drum (300) as the vacuum imaging drum (300) rotates. The printhead (500) receives information signals and produces radiation which is directed to the donor sheet material (36) which causes color to transfer from the donor sheet material (36) to the thermal print media (32). The vacuum imaging drum (300) provides vacuum on its surface by means of a first plurality of holes. A second plurality of holes maintains a boundary layer (336) of air along the drum surface.

Abstract: An extruded, tiered high fin density heat sink (10) uses extruded first base, second base and bridging elements (12, 16, 14) having an arrangement of closely spaced, parallel fins (20, 26, 32, 38) and recesses (22, 28, 34, 40) for receiving opposing fins in the elements. The fins (20, 38) in the first and second base elements (12, 16) are bonded to recesses (28, 34) in opposite common faces (24, 30) of bridging elements (14) while fins (26, 32) extending from both opposing faces (24, 30) of bridging element (14) are bonded in aligned recesses (22, 40) in the first and second base element (12, 16) forming an extruded, tiered, high fin density heat sink (10).

The image processing apparatus (10) comprises a vacuum imaging drum (300) for holding thermal print media (32) and dye donor sheet material (36) in registration on the vacuum imaging drum (300). A printhead (500) moves along a line parallel to the longitudinal axis (X) of the vacuum imaging drum (300) as the vacuum imaging drum (300) rotates. The printhead (500) receives information signals and produces radiation which is directed to the dye donor sheet material (36) which causes color to transfer from the dye donor sheet material (36) to the thermal print media (32). The vacuum imaging drum (300), having media contours (328) on the outer surface to facilitate holding media onto a vacuum imaging drum (300) revolving at high speeds.

Abstract: An improved heat exchanger (10) has an extruded, multi-tiered heat sink (22) having a very high heat transfer coefficient structurally associated with a compact, high air velocity air moving means (14). Heat sink (22) has a first tier (56) formed by first fins (34) in a first base element (24) closely spaced apart from third fins (40) in an extruded bridging element (30). A second tier (60) of heat sink (22) is formed by second fins (52) in a second base element (26) closely spaced from fourth fins (46) opposing the third fins (40) in the bridging element (30). Air moving means (16) of the invention employs a backward curved impeller (14) driven by a compact planar dc motor (80) adapted to yield higher than normal impeller speeds with superior thermal transfer performance.

Abstract: A high performance, high pin fin density heat sink (10) has mating first and second opposing base members (22, 24) having first and second pin fins (18, 20) extending generally perpendicularly therefrom. The pin fins (18, 20) are generally cylindrical and each bonded into recesses (30,32) formed on the opposing base member (22, 24). The spaces between nearest adjacent first and second pin fins (18, 20) form narrow fluid passageways (12) having a gas inlet in (14) for communicating with a heat generating body and gas out let end (16).
