Schematic diagram of the flow-through heat sink
Grahic Jump Location
Schematic diagram of the impingement heat sink
Grahic Jump Location
Schematic diagrams showing different fin shapes used in analysis cases (a) through (f) in Table 3, respectively
Grahic Jump Location
The velocity vectors (m/s) and pressure contours (N/m2) for analysis cases (a) through (f), respectively. The pressure contours are equally spaced over the total range from 0 to the value in Table 3.
Grahic Jump Location
(a) and (f) are the temperature contours (C) for analysis cases (a) and (f), respectively. 1822 W is applied at the base. The contours are equally spaced over the total temperature range shown in the figure.
Grahic Jump Location
(a) to (f) are the temperature profiles (C) at z=0, 10, 30, and 50 mm for analysis cases (a) through (f), respectively. The temperatures are shown for the air in the middle of the channel as well as for the corresponding fin temperature. The temperatures correspond to the bottom of the 5 mm thick heat sink base. The x direction refers to the distance from the centerline in meters.
